CN103887633A - Socket and strip with multiple perpendicular metal sheets serving as conductive contacts - Google Patents

Abstract

Two or three metal sheets used for making contact with metal insertion rods of a plug are arranged inside a common socket and strip, and surface modeling is mainly adopted for the metal sheets. In the actual use process, a quite small number of contacts exist between the metal insertion rods of the plug and the bent metal sheets inside the socket and strip, and therefore the contact area is small, when the current is large, the metal insertion rods of the plug and the metal sheets inside the socket and strip will emit heat, and even a plastic shell of the socket and strip can be melt; in addition, due to the fact that arcs are generated due to separation of the contact faces between the metal insertion rods of the plug and the metal sheets inside the socket and strip, and the heat emitting speed is higher. A socket and strip with the multiple perpendicular metal sheets serving as conductive contacts solves the technical problem of increasing the number of the conducive contacts and enlarging the conductive contact area between the metal insertion rods of the plug and the metal sheets inside the socket and strip by increasing the number of the metal sheets inside the socket and strip.

Description

Utilize socket and the insert row of multiple vertical metal sheets as conductive contact

Technical field

Belong to appliance field.

Background technology

Common socket is inner with insert row is all two or three for the sheet metal contacting with the metal inserted link of plug, and sheet metal adopts surface modeling more; In the time that reality is used, sheet metal contact point bending in the metal inserted link of plug and socket and insert row is little, so contact area is very little, in the time that electric current is larger, sheet metal in metal inserted link and socket and the insert row of plug can generate heat, and even can melt the plastic casing of socket and insert row; In addition, between the metal inserted link of plug and the sheet metal of bending, produce electric arc because contact-making surface divides defection, the temperature of socket and insert row raises rapidly, can initiation fire.

Summary of the invention

Technical problem to be solved is:

By increasing the quantity of sheet metal in socket and insert row, play and increase the metal inserted link of plug and the quantity of conductive contact point and the effect of enlarge active surface of socket and insert row interior metal sheet.

Technical scheme:

Utilize socket and the insert row of multiple sheet metals as conductive contact, it is characterized in that: the contact chip of socket or insert row inside is made up of sheet metal and the short sheet metal of long sheet metal, moderate-length, the sheet metal of long sheet metal, moderate-length is connected with metab is vertical respectively with short sheet metal, and the sheet metal of long sheet metal, moderate-length and the end of short sheet metal have crotch.

Brief description of the drawings

Fig. 1 is the profile of socket and insert row, the detail structure figure that multiple sheet metals and the metab that Fig. 2 is socket or insert row forms.

Numeral and letter on figure are represented as:

1, plug, 2, the metal inserted link of plug, 3, the shell of socket or insert row, 4, the long sheet metal of socket or insert row, 5, the sheet metal of the moderate-length of socket or insert row, 6, the short sheet metal of socket or insert row, 7, the metab of socket or insert row inside, 8, the wire of socket or insert row, 9, the crotch of sheet metal end.

Embodiment

The sheet metal 5 of long sheet metal 4, moderate-length is connected with metab 7 is vertical respectively with short sheet metal 6, and the end of sheet metal has crotch 9, and the metal inserted link 2 of being convenient to plug freely plugs, and the terminal hook 9 of all sheet metals can contact with the metal inserted link 2 of plug; Metab 7 is fixed on the outer casing inner wall of socket or insert row, and wire 8 and the metab 7 of socket or insert row interconnect.

Claims (1)

1. utilize socket and the insert row of multiple vertical metal sheets as conductive contact, it is characterized in that: the contact chip of socket or insert row inside is made up of sheet metal and the short sheet metal of long sheet metal, moderate-length, the sheet metal of long sheet metal, moderate-length is connected with metab is vertical respectively with short sheet metal, and the sheet metal of long sheet metal, moderate-length and the end of short sheet metal have crotch.
