Description

SAFETY WIRE CONNECTOR
Technical Field The present invention relates to a safety wire connector that can be safely used by overcoming drawbacks of a conventional insert-type connector that has been used to connect cords, cables, wire harness and other electrical wires.
Background Art FIG. 1 is an exemplary view illustrating a conventional wire connector. The wire connector has a plug 11 and a receptacle 13 each attached to the end of each of two groups of wires. The plug 11 and the receptacle 13 have conductive pins or terminals 15 mounted within the housings thereof, respectively, so that the plug 11 is inserted into the receptacle 13 to allow them to be electrically connected to each other. However, it is not easy to decouple the plug and the receptacle of the insert-type connector of FIG. 1 from each other once they are coupled to each other. Due to this, this type of the connector is disadvantageous in that it is unsuitable for a place where the connector must be frequently attached or detached.
Furthermore, this conventional connector is not adequate for a use where it is preferred that the two groups of connected wires are to be separated in time of need. For example, it may include a case where the connector must be separated so that the two groups of wires do not get damaged due to tension occurring when one group of wires are pulled against the counterpart group of wires, or a case where the safety may be endangered. For instance, in the case where one turns over in sleep while having a headphone or an earphone worn on his or her head, there is a risk that an accident may happen since the wires of the headphone or the earphone are wound up around the neck. Moreover, if an acoustic device becomes greater apart than the length of the earphone wire with a plug of the earphone being inserted into a jack of the acoustic device, there are problems in that the coupled portion of the jack and the plug which are being connected to each other is damaged, etc.
There is therefore a need for a new wire connector that can overcome the problems of the conventional insert-type wire connector and that can be easily coupled/decoupled.
Disclosure of Invention
Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a safety wire connector that can be easily coupled/decoupled in a contact type using a magnet and that can secure the safety of a user using the connector.
Another object of the present invention is to provide a safety wire connector having permanent magnets attached to its both ends unlike a conventional insert-type connector, thereby reducing a contact resistance between a contact pin and a terminal.
In order to achieve the above objects, the present invention has its basic principle in constructing the wire connector in the contact type unlike the conventional insert-type connector. In other words, respective permanent magnets are attached to both ends of the connectors for connecting the two wires. In this state, if these two connectors approach each other, they are coupled to each other by means of a magnetic force of the permanent magnets. Points to be considered when fabricating the connector of the contact type may include the following:
First, if the connector is fabricated in the contact type as in the present invention unlike the conventional forced-insertion type, there is a possibility that a contact resistance between the terminals to be connected may be increased. It is thus required to solve this problem in structure.
Next, in the case where a plurality of wires are connected, the connector must have a structure in which each wire can be easily and independently connected even when the two connectors come into contact with each other with no special effort of a user, like that the insertion direction of the plug and the receptacle is decided depending on the shape of the housing.
Brief Description of Drawings
Further objects and advantages of the invention can be more fully understood from the following detailed description taken in conjunction with the accompanying drawings in which:
FIG. 1 is an exemplary view illustrating a conventional wire connector, FIG. 2a and FIG. 2c are cross-sectional views illustrating safety wire connectors according to one embodiment of the present invention, FIG. 2b is a detailed view illustrating a contact pin 106 shown in FIG. 2a, and
FIG. 3 a to and FIG. 3 b illustrate safety wire connectors according to another embodiment of the present invention.
Preferred Embodiment for Carrying out the Invention The present invention will now be described in detail in connection with preferred embodiments with reference to the accompanying drawings.
Embodiment 1 FIG. 2a is a longitudinal cross-sectional view illustrating a safety wire connector using a magnet according to one embodiment of the present invention.
The safety wire connector includes a first housing 100 and a second housing 200. The first housing 100 and the second housing 200 are coupled to each other so that one group of wires from the first housing 100 and the other group of wires from the second housing 200 are connected to each other. The first housing 100 and the second housing 200 are machined to have internal hollow spaces, into each of which the respective group of wires can be inserted. A concave depression portion 102 and a convex protrusion portion 202 are formed, respectively, at free ends of the first housing 100 and the second housing 200 which are in contact with each other. The depression portion 102 and the protrusion portion 202 ensure that the first housing 100 and the second housing 200 are correctly coupled to each other when both the housings are brought into close contact with each other.
Permanent magnets 104 and 204 are mounted within the respective housings with them abutting the depression portion 102 and the protrusion portion 202. At this time, if both the magnets are the permanent magnet, it is required that they have different polarities. If the two magnets have the same polarity, they will have a repulsive force.
According to a basic concept of the present invention, however, there is no problem if one of the two magnets is a permanent magnet and the other is a magnetic substance made of iron, nickel, etc. In this embodiment, it is assumed that both the magnets are the permanent magnets in order to enhance a contact force of the first and second housings. A great contact force can thus be obtained even with the permanent magnets of a relatively small size.
A plurality of contact pins 106 are partially buried into the depression portion 102 of the first housing 100. Further, a plurality of terminals 206 are partially buried into the protrusion portion 202 of the second housing 200. It can be seen from FIG. 2a that the contact pins 106 are slightly protruded outwardly from an end face of the first housing 100 whereas the terminals 206 are slightly depressed inwardly from an end face of the second housing 200. For this purpose, the end face of the second housing 200 is slightly grooved to be coaxially with the terminals to form grooves, so that the ends of the contact pins 106 fit into the grooves to be connected to those of the terminals 206.
FIG. 2b is a detailed view illustrating the contact pins 106 buried in the first housing 100.
A movable pin 110 is inserted into a pin cylinder 108, at which time, the movable pin 110 is always applied with a force that pushes it outwardly by means of a resilient force of a spring 112. If it is needed to push the movable pin 110 from the right to the left in FIG. 2b, it is required that a constant force be applied to the pin 110 by means of the resilient force of the spring 112. In other words, in a state where the movable pin 110 is once inserted, a force that pushes the pin 110 outwardly (from the left to the right in FIG. 2b) always exists. Such contact pins shown in FIG. 2b are called "Pogo pins" that have been widely used in a semiconductor test jig, etc.
With this arrangement, when the first housing 100 and the second housing 200 are coupled to each other, the contact pins 106 may come into firm contact with the terminals 206. FIG. 2c illustrates a state where both the housings 100, 200 are coupled to each other. The depression portion 102 and the protrusion portion 202 are firmly coupled to each other by means of the two permanent magnets 104 and 204. The contact pins 106 are brought into firm contact with the terminals 206 by means of the spring.
Embodiment 2
It has been described in the first embodiment that the number of each of the contact pins and the terminals is two: one is disposed above and the other below. In actual applications, however, a plurality of the contact pins and the terminal are used. It should be noted that the structure in this case is the same as that in the first embodiment. If the plurality of the contact pins and the terminals need to be connected with each other, the separate group of a kind whose contact pins and terminals are matched with each other must be brought into contact. Accordingly, it is required that the first housing 100 and the second housing 200 be brought into contact with each other only in one direction.
To this end, various modes below can be adopted.
As shown in FIG 3a, projection keys 114 are formed in a depression portion 102 of the first housing 100 in such a manner that each of them is projected inwardly from a part of the inner circumferential surface of the depression portion 102 toward the center of the depression portion 102. Key grooves 214 are formed in the protrusion portion 202 of the second housing 200 to allow the projection keys 114 to be received therein in such a manner that each of them is grooved inwardly from a part of the outer circumferential surface of the protrusion portion 202 toward the center of the protrusion portion. The first housing 100 and the second housing 200 will be accordingly coupled to each other only when the projection keys 114 and the key grooves 214 are coincident with each other in their engagement direction and angle.
Furthermore, a plurality of key pins 114' are formed within the depression portion 102 at given locations deviated from the center of the depression portion. A plurality of key pinholes 214' are formed on the protrusion portion 202 at given locations deviated from the center of the protrusion portion, so that each of the plurality of key pins 114' is inserted into a corresponding one of the plurality of key pin holes 214'. It can be seen from the above description that the first housing 100 and the second housing 200 will be coupled only when the key pins 114' and the key pinholes 214' are coincident with each other in their locations.
The above case is feasible when the first housing 100 and the second housing 200 are brought into contact with each other in a state where the engagement direction and angle thereof are made identical to each other. For this reason, there is a disadvantage in that a little time is required to allow the first and second housings to contact each other. In order to overcome this problem, the housing may have a shape as shown in FIG.
3b. By doing so, even if the first housing 100 and the second housing 200 are brought into contact at any location, they will be coupled at their exact location with slight movement. As shown in FIG. 3b, the depression portion 102 of the first housing 100 and the protrusion portion 202 of the second housing 200 are each machined to have a claw shape of a known machine element, that is, an engagement clutch. Similarly to the operation of the claw clutch, the first housing 100 and the second housing 200 will be exactly coupled to each other via the claw even if they come into rough contact with each other.
As described above, according to the present invention, the safety wire connector can be constructed in the contact type by the magnetic force of the permanent magnet. Therefore, the safety wire connector of the present invention can be more easily coupled/decoupled even with a small force, compared to the conventional insert-type connector. Accordingly, the present invention has a new effect in that it can safely protect users, devices, etc. from a danger occurring due to wires being pulled.
Furthermore, the safety wire connector of the present invention can be effectively applied to a portable cassette recorder, a CD player, a MP3 player, a mobile phone, a sound-to-vibration converter, a hands-free device installed inside a vehicle, and the like.
While the present invention has been described with reference to the particular illustrative embodiments of the safety wire connector using a magnet, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
