Abstract

The utility model relates to a composite multi-channel connecting terminal, which comprises a wire nose (10) and a wire lug (20), wherein, a wire connector (30) for connecting an auxiliary wire cable is also arranged on the wire nose (10), and the wire connector (30) comprises a wire connecting sleeve (31) or a platy connector; the wire connecting sleeve (31) can be provided with a tightening screw or a spring leaf; a plurality of wire connectors (30) can be arranged on the wire nose (10). The proposal of the utility model adopts the processes that after a main wire cable M is pressed and installed in the wire nose (10), an auxiliary wire cable N required to be connected on the terminal is fixed on the accessional wire connector (30), therefore, a plurality of wire cables can be simultaneously connected on one connecting terminal, the phenomena of the contact is loose and the thin wire cable is broken caused by the mutual disturbance of the wire cables can be avoided, and simultaneously the failure that the contact resistance is large and easy to be burnt caused by overlapping and pressing of a plurality terminals on one binding post is also avoided.

Description

Compound Multipath binding post

Technical field the utility model relates to arrangements of electric connection, particularly is used for the binding post that cable connects.

Background technology is present, in the rack series products of electric power, electronic applications, usually need draw a plurality of circuits at a conductive pole place, just want two of crimping or many cables, and the traditional method of this crimping/connection is all to press-fit binding post separately every cable ends, adopt the overlapping crimping in a plurality of terminations of a plurality of cables at this conductive pole place, the shortcoming of this mode is, the many overlapping crimping complex process in a plurality of terminations of cable, contact resistance is big, easily heating, crimping closely very easily do not cause scaling loss.Also have is exactly to adopt to fill in many cable crimping simultaneously in the crimp head of a standard bore, adopt many cables to be crimped on the interior method of a crimp head, often because size does not match, the Thin cable fragility causes pulling capacity not enough, the situation that Thin cable breaks, perhaps, cause loose contact because the Thin cable crimping is not tight, even the phenomenon that comes off.Above-mentioned two kinds of methods, not only assembling is relatively more difficult, and fail safe is also relatively poor.

Utility model content the utility model provides a kind of compound Multipath binding post, adopts the mode that increases the wiring joint on a terminal, solves uneven or overlapping crimping of a plurality of terminals and technical problem of poor safety of each cable crimping in the prior art; Further adopt disassembled fastening method, make things convenient for the separation between each cable on this terminal, provide convenience, improve design of the present utility model for maintenance.Employing is provided with the method for a plurality of joints on a terminal, further solve the technical problem of multi-thread connection.

Design of the present utility model is, designs a kind of compound Multipath binding post, comprises the coupled line ear that is used for the socket binding post of the line nose that is used for the interlock main cables; Also be provided with the electric wire connecting junction that is used for the auxiliary connection cable on the described line nose.This programme is after press-fiting main cables in the online nose, the by-pass cable that again needs is connected on this terminal is fixed on the additional electric wire connecting junction, like this, can on a binding post, connect a plurality of cables simultaneously, and each cable all has independently connecting portion, avoid the phenomenon that loose contact that causes interfering with each other or thin cable be pressed down to take place, simultaneously, also avoided overlapping the press-fiting of a plurality of cross-talks on same binding post and the contact resistance that causes is big, the fault of scaling loss easily.

This electric wire connecting junction comprises the wiring sleeve, and its endoporus can penetrate for the by-pass cable end.The open sleeve that can adopt the camber line sheet of button in two and surround or the sleeve of remaining silent of die cast, the form identical with the main line nose adopts the mode auxiliary connection cable that press-fits.Also can adopt the mode that adds cable fixer on the sleeve of remaining silent, after the by-pass cable penetrates endoporus, compress the by-pass cable with fixture, assurance contacts good and prevents to come off.

Cable fixer can adopt the fastening mode of screw, for example is arranged at screw and associated trip bolt on the wiring sleeve cylindrical shell, after the by-pass cable penetrates endoporus, screw screw, it is closely connected that by-pass cable and terminal are compressed, simultaneously, also fixed the by-pass cable, prevented to come off; Can also adopt the mode of spring compression, for example: be arranged at the spring leaf of the endoporus the inside of wiring sleeve, after the by-pass cable penetrates endoporus, rely on the recovery elastic force of spring leaf, it is closely connected that by-pass cable and terminal are compressed.

Described line nose is provided with a plurality of electric wire connecting junctions, on same terminal a plurality of switch elements can be set, and can connect more by-pass cable.

After the utility model adopts above-mentioned technical scheme, can make this novel compound binding post have the function that connects a plurality of circuits, broken away from the present situation that relies on many cables of a plurality of terminal crimping in the current enclosure product, also broken away from simultaneously the present situation that adopts the cable that standard aperture many thicknesses of terminal crimping do not wait, and, each cable connects separately, avoided the crimping inequality, loose contact and the phenomenon that comes off easily, can reduce and on same binding post, press-fit the quantity of terminal and reduce binding post quantity in the rack as far as possible, simultaneously, also improve fail safe and reliability.And, can separate easily between each cable in the same terminal, the cable that therefore has this place's connection can repeatedly be changed wire rod, and the characteristics of compatible different cross section cable, also is very easy to maintenance.Simultaneously, compound binding post of the present utility model can be used as independently union piece and produces in batches, has low contact resistance, simple in structure, production and characteristics easy to use.
