Abstract

A terminal connector for switch plug consists of a bolt 1, a wire frame 2 and a wire board 3, wherein the wire frame 2 is formed by bending a metal sheet, end pieces of both ends of the metal sheet are overlapped to form a top side of the wire frame, the bottom side of the wire frame 2-3 is cone shaped; the wire board(3 is a w-shaped metal sheet, a top plate 3-1 arranged in the middle of the wire board is encased into the wire frame, the bolt 1 is screwed into the wire board to pull the wire frame to make a translation motion, when the bottom side of the wire frame moves closer to the top plate, the external wire terminal which is arranged on the bottom side of the wire frame 2-3 is tightly clamped, thereby, the external wire is tightly clamped. The terminal connector has the advantages of being uneasily damaged, along with close and firm connection and good contact between terminals and wires. The utility model is widely applied to the connection of wires or wire combinations with different wire sizes. The bolts of the terminal connector for switch plug are firmly locked in a position and can not be screwed out, thereby avoiding the falling off and losing of the bolts. The utility model can be applied to all types of electric connectors.

Description

The binding post of combined socket and switch

Technical field

The utility model relates to the binding post of the spare and accessory parts of a kind of switch or socket, particularly a kind of combined socket and switch.

Background technology

In existing switch or socket, use a kind of copper binding post in a large number, this kind terminal places the base of switch or socket, and the terminals of external wire, penetrate in this base, be electrically connected with binding post, thus the electric loop of formation combined socket and switch.Existing binding post has three kinds of patterns basically, and a kind of is the elastic clip chip, connects fast fast simply, only is applicable to the sub-thread thick copper lines, is not suitable for the multiply copper cash, especially the copper cash that differs of thickness; A kind of is the screw clamp template, connection space is narrow, the incompatibility heavy gauge wire also has a kind of screw/cylinder type, is to be made of a little intercept cylindrical drum and a brass screw, on the side of cylindrical drum, have a screw, screw is screwed in this screw, and screw head is pushed up the external wire that penetrates in this cylindrical drum, pushes its terminals, make on its inwall that is close to cylindrical drum, thereby realize being electrically connected of external wire and binding post.This electric connecting mode because conductor wire end is expressed on the barrel by screw, might be loose by crowded by the tiny copper wire of a part, has reduced contact area; Copper wire that also might a part of binding post has been squeezed off through extruding repeatedly, has damaged lead.The increase that these all cause contact resistance is difficult to guarantee the good electrical contact of binding post on the combined socket and switch.And above-mentioned screw also is easy to drop in disassembly process and loses.

Summary of the invention

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provide a kind of electric contact well, firmly, can not the damage wires end, be used for the binding post on the combined socket and switch.

The purpose of this utility model can reach by following measure:

Binding post on a kind of switch or the socket includes screw, wire frame, and wherein screw is from wiring

Binding post on a kind of switch or the socket includes screw, wire frame, and wherein screw screws in this frame from a lip-deep screw of wire frame.The terminal block that also has " mountain " font of forming this terminal, this terminal block constitutes " mountain " font by top board in the middle of it and each wing plate of both sides.Top board in the middle of this terminal block, when being nested in the wire frame from the side, the wing plate of its both sides then is limited in the outside of wire frame.Also can be provided with a fritter baffle plate on the direction vertical on the terminal block, penetrate the degree of depth in the wire frame in order to the restriction top board with top board.Screw screws in wire frame by screw, and at top board by the top of screw institute roof pressure, and when making the terminal block translation; Perhaps with regard to relative motion, under top board is fixed situation, screw in screw, the translation of pulling wire frame, by at the bottom of the wire frame with the furthering of top board, with placing the terminals of the external connection lead in the wire frame, closely contact with wire frame.

Above-mentioned wire frame is to be formed by the bending of sheet metal, is superimposed into the end face of frame by its two dististyle, forms the column casing of a hollow, has the screw that can screw in screw on the end face; And at the bottom of being the frame of a taper with respect to the bottom of end face.Like this, be more convenient for compressing the terminals of the external wire that is in this bottom.And double-deck end face is not reason perforate and lower its intensity also.Make also very simple and efficient.

The utility model binding post has following advantage than prior art:

1, be electrically connected closely, firmly, reliable.Owing to abolished the direct fashion of extrusion of prior art, change the terminals that push lead by screw indirectly, both made contact closely, can not damage terminals again.

2, after the utility model binding post was disposed in the base of combined socket and switch, the position of screw was fixed, and screw need not to screw out and leave wire frame in the assembling and dissembling process.During the turn screw, only wire frame translation in each part, terminal block and screw all do not leave the origin-location, the average case of having avoided screw to lose because of dropping; Also can't see the screw that exposes, it is whole specious to assemble the back.

3, applicability is wide, both has been applicable to sub-thread or multi cord, no matter also the thickness of external wire is not of uniform size, all can clamps and does not get loose.

The utility model is described in further detail below in conjunction with drawings and Examples.
