Description

The binding post of termination

The utility model relates to the binding post of a kind of components and parts of electric equipment, particularly a kind of termination.

In various terminations, binding post is important components and parts, play a part to be fastenedly connected, connection closely whether, directly have influence on the function of use and the life-span of electric/electronic device again.Other components and parts in binding post and the termination, for example cooperation between terminal screw, wire frame, the terminal block and assembly relation are the factors that influences the binding post design.People always wish the simple in structure of this terminal, are easy to processing, but wish that its intensity is higher, and bending resistance is withstand voltage, can not be squeezed when tightening termination and are out of shape.Shortcoming is to some extent considered in the design of existing binding post aspect the resistance to compression bending strength of strengthening terminal.

The purpose of this utility model is to provide a kind of simple in structure, handling ease, connection closely and the binding post of can bending resistance withstand voltage termination.

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

The utility model binding post is to use the binding post in various terminations, be specially adapted to the termination of circuit breaker, for example by last terminal screw, in molecular first termination of last wire frame and terminals, and by following terminal screw, in molecular second termination of following wire frame and terminals.The utility model binding post can pack into from the side indentation, there of last wire frame in this wire frame, makes screw/be threaded with the last terminal screw that passes wire frame then; Also can pack into this time wire frame, wire frame is finalized the design at last, the following terminal screw that passes down wire frame be screwed in the screw of this binding post, thereby form second termination from the indentation, there on the following wire frame side.

The utility model binding post is by a sheet metal, and for example common straightcarbon steel is bent into a square frame, plates the anticorrosion metal at last and makes.The sheet metal two ends of above-mentioned bending overlap at the end face place of square frame, and are closely overlayed together.Wherein a top end of sheet metal end face stretches out the tongue piece 1-1 of a fritter major part, this tongue piece 1-1 be pressed into leave on the square frame side with the same shape of tongue piece and the size breach in, being attached at this tongue piece 1-1 on the end face after imbedding becomes the part of side, like this, encircle into once the whole square frame of circle very firmly, and process simple and efficient.

Have the screw 1-2 that screws in for terminal screw at the square frame top of binding post, on the inner surface of square frame bottom surface, offer the striped 1-3 of some roads projection.

The utility model binding post, simple in structure, both be convenient to processing and assembling, can improve the strong degree of wiring again, be applicable to two or more terminations, do dual wiring and use, because the end face of terminal and bottom surface, cooperate with wire frame all to can be used as a wiring position.For example, between the bottom surface and wire frame bottom surface of terminal, just be suitable for inserting external wire; And, making the intensity of terminal itself greatly strengthen because the end face and the side of terminal have a fritter tongue piece to rabbet mutually, resistance to compression is anti-curved, not yielding, is particularly suited for using in the time will strengthening the wiring contact friction force.

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

Description of drawings;

Fig. 1 is the stereogram of first termination;

Fig. 2 is its front view;

Fig. 3 is the second termination front view;

Fig. 4 is its stereogram;

Fig. 5 is the binding post right view of (comprising the binding post in first termination and second termination);

Fig. 6 is the front view of this binding post;

Fig. 7 is the left view of this binding post;

Fig. 8 is the vertical view of this binding post.

Among each figure, 1 is the binding post in first termination, the 2nd, and last wire frame wherein, the 3rd, last terminal screw wherein; 4 is the binding posts in second termination, the 5th, and following wire frame wherein, the 6th, following terminal screw wherein, 1-1 are the tongue pieces on the binding post, and 1-2 is the screw on the terminal, and 1-3 is the striped of terminal bottom surface upper process.

Embodiment:

As shown in drawings,, be bent into the square frame of the binding post 1 of a hollow, (for the purpose of standardization, binding post 4 is made the structure identical with terminal 1) with machining process with a #45 carbon steel.The two ends of this steel disc overlap at the end face of square frame, and quilt is overlayed into a composite sheet, top a slice is stretched out the tongue piece 1-1 of a fritter major part, to 90 ° of angles of bending, side, be pressed in the breach on this side, the shape of breach size is the same with tongue piece, make tongue piece and breach complementation, tongue piece 1-1 and this side pressing become one, and the phase embedding of this tongue piece has greatly improved the intensity of square frame.End face at square frame has screw 1-2, and on the inner surface of square frame bottom surface, then processes the striped 1-3 of some roads projection.At last binding post 1 or binding post 4 are plated the anticorrosion metal.The binding post of making thus both can be socketed into first termination mutually with last wire frame 2 and last terminal screw 3, also can be socketed into second termination mutually with following wire frame 5 and following terminal screw 6.The utility model is not limited to specifically described execution mode.

Claims (2)

1, a kind of binding post of termination, comprise the binding post (1) that combines first termination with last wire frame (2) and last terminal screw (3) socket, or combine the binding post (4) of second termination with following wire frame (5) and following terminal screw (6) socket, it is the square frame that is pressed into by the sheet metal two ends overlapping of a bending, the end face of square frame has screw (1-2), it is characterized in that, a top end of above-mentioned sheet metal end face stretches out and bends the tongue piece (1-1) of a fritter major part, this tongue piece (1-1) is embedded in the breach that shape is all the same with size on the above-mentioned square frame side, is linked to be with this square frame side to be one.

2, the binding post of termination according to claim 1 is characterized in that, the striped (1-3) of some roads projection is arranged on the bottom surface of described square frame.
