Embodiment
At first please refer to Fig. 1 to shown in Figure 5, be a preferred embodiment of the present invention schematic diagram.Electric connector of the present invention includes an insulating body 10, it has a fitting portion 11 can be in order to mutually chimeric with the other side's connector and reach electric connection, its both sides respectively are provided with a latching device 12, respectively be provided with a step 13 in latching device 12 inner edges, step 13 is provided with plural lower fixed hole 131 and a positioning block 132, be embedded with a plurality of terminals 14 on insulating body in addition, each terminal all has contact site 141 and elastic portion 142, and contact site 141 is exposed on fitting portion 11 1 sides;
Flexible flat cable 20 is to coat the structure that complex lead constituted by insulating barrier, and it is simultaneously gone up in end and forms the plural contact 21 that exposes, and on the another side of these contacts 21, forming a metal level 22; Loam cake 30, can from top to bottom cooperate on the step 13 that is assembled in insulating body 10, its both sides are provided with the last fixing hole 31 corresponding to lower fixed hole 131, reach groove 32 corresponding to locating piece 132, what loam cake 30 can be stable by this is positioned on the insulating body 10, in addition, loam cake 30 also is provided with at least one breach 33.In the present invention, loam cake 30 is to be used for pressing flexible flat cable 20, contact 21 elastic portion 142 formation can be stable and terminal 14 of flexible flat cable 20 are contacted, before assembling loam cake 30, can earlier the one side of flexible flat cable 20 in contrast to contact 21 be sticked on the loam cake 30, together be assembled on the insulating body 10; At last, utilize a metallic casing 40 cover to be overlying on loam cake 30 tops again and form with insulating body 10 and to interfix.Please be simultaneously with reference to Fig. 4 and Fig. 5, shell 40 is provided with plurality of fixed sheet 41, at least one shell fragment 42 and fin 43.Stator 41 can pass fixing hole 31 and lower fixed hole 131, again stator 41 front ends are bent, use the three is fixed, shell fragment 42 can pass the breach 33 of loam cake 30 and contact with metal level 22 formation of flexible flat cable 20, make this electric connector combination can reach stable earth-continuity, fin 43 can be used for strengthening compressing the strength of loam cake 30, makes contact 31 can fully reach pressing with the elastic portion 142 of terminal 14 and contacts.
In addition, the latching device 12 that is formed at insulating body 10 both sides at least respectively comprises an operating portion 121, a holder 122 and a locking bar 123, locking bar 123 is contained in the holder 122, make the fixing point 124 of locking bar 123 protrude in fitting portion 11 both sides, and the protuberance 125 of locking bar 123 is positioned at the position of corresponding operating portion 121, the user can make fixing point 124 form resilient movement by press operating part 121 drive protuberances 125, uses to constitute fixing fixing with releasing with the other side's connector.
The present invention utilizes the preferable terminal 14 of structural strength, dimensional accuracy as the conductor between flexible flat cable 20 and the other side's connector, avoid the more weak flexible flat cable contact 21 of intensity because of plug is impaired repeatedly, and when the terminal of both sides' connector is in contact with one another, can have more accurate polarization; In addition, when the demand of transmission system has change, for example: in the time of must removing the part electrical contact, structure of the present invention can cooperate and removes partly terminal at any time with the compliance with system actual needs, if then can't remove contact arbitrarily as the flexible flat cable of conventional approaches.
Moreover, the present invention utilize loam cake 30 from top to bottom the mode of pressing flexible flat cable 20 replace the fixed form of drawing formula, make flexible flat cable 20 more accurate on the location, be difficult for deviating from, and be easy to retrieve replacing.
Next introduce second preferred embodiment of the present invention, compared to last preferred embodiment, this second preferred embodiment purpose is at the electric connector structure of the flexible flat cable combination that a kind of applicable different structure sample attitude is provided.Please refer to Fig. 6 to shown in Figure 8, the electric connector combination mainly is that sheet metal 50 is constituted under being reached by insulating body 10, flexible flat cable 20, loam cake 30, shell 40.Insulating body 10 has a fitting portion 11 can be in order to mutually chimeric with the other side's connector and reach electric connection, its both sides respectively are provided with a latching device 12, respectively be provided with a step 13 in latching device 12 inner edges, step 13 is provided with a plurality of lower fixed holes 131, a positioning block 132 and a guide channel 133, on insulating body, be embedded with a plurality of terminals 14 in addition, each terminal all has contact site 141 and elastic portion 142, and contact site 141 is exposed on fitting portion 11 1 sides.
Flexible flat cable 20 is to coat the structure that complex lead constituted by insulating barrier, and it is simultaneously gone up in end and forms the plural contact 21 that exposes, and can form a metal level 22 simultaneously on any one side of flexible flat cable 20 or two sides.
At last, with following sheet metal 50 is that the side direction assembling is fixed in the guide channel 133 of insulating body 10, make down sheet metal 50 relative positionings in the below of flexible flat cable 20, in forming at least one shell fragment 51 on the sheet metal 50 down towards flexible flat cable 20 projections, making shell fragment 51 directly form ground connection with the metal level 22 of flexible flat cable 20 contacts, in addition, the following sheet metal 50 of being located at flexible flat cable 20 belows must form with shell 40 and contact, and makes the ground connection signal shell 40 that can lead smoothly.
Design in this second preferred embodiment, be that metal level 22 is located on the two sides of flexible flat cable 20, making metal level 22 form quiet earth simultaneously with the shell fragment 42,51 of shell 40 and following sheet metal 50 simultaneously contacts, anti-, even flexible flat cable 20 only has the monolateral metal level 22 that is provided with, also can reach stable ground connection contact.Thus, electric connector of the present invention combination be applicable to the flexible flat cable with different structure sample attitude (metal level 22 can be located on the arbitrary face), do not need the variation because of metal level 22 positions again, and the structure of change connector.Moreover structural design that can be is as shown in Figure 9 only forming shell fragment 51 on the sheet metal 50 down, and is omitting the shell fragment 42 on the shell 40, also is a kind of design variation of the present invention.
