Abstract

The utility model provides a roll up and restraint free accommodation metal sinle silk in conductor crimping district, and insulating riveting district coordinates with one section insulating skin riveting at least that connection structure of terminal and wire, terminal are equipped with conductor crimping district and insulating riveting district, and the insulating skin segmentation of wire sets up, is naked metal sinle silk between two sections adjacent insulating skins, the terminal. Conductor crimping district does not excessively oppress with the contact of metal sinle silk, has avoided plain conductor to influence the ability of overflowing because of deformation, and conductor crimping district presss from both sides between the insulating skin in both ends in addition, can be with the help of complex firmness between adhesive force improvement terminal between insulating skin and the metal sinle silk and the wire.

Description

The syndeton of terminal and wire

Technical field

The utility model relates to the syndeton of a kind of terminal and wire. This structure had both been applicable to forceful electric power field, was also suitable for the field of low-voltage, high-current or the little electric current of low pressure.

Background technology

Existing terminal generally comprises conductor crimping district and insulation riveting district, when terminal is connected with wire, conventionally by the insulated hull strip off of wire front end, make the metal wire core retainer plate of wire enter terminal conductor crimping district compression, and the rear end part of conductor strip insulated hull compress in insulation riveting district. this crimping mode compresses wire effectively, but likely the metal core of wire is pressed to obtain to distortion simultaneously, specifically, in conductor crimping district crimping process, likely there is the situation that flies silk or break in metal core, and crimping process can cause the roundness deficiency of metal core, and likely cause compression joint area to tail off, so not only reduce the conveyance capacity between wire and terminal, cause between terminal and wire and generate heat, increase wire due to the temperature electric energy loss causing that raises, and likely cause the danger of the caused on fire or short circuit of rising due to temperature. there are numerous producers for overcoming these shortcomings, use the wire of reinforced insulation or use protecting high temperature, cause manufacturing cost to increase. for overcoming these defects, spy improves the syndeton of terminal and wire.

Summary of the invention

Technical problem to be solved in the utility model is the syndeton that a kind of terminal and wire will be provided, and it not only connects reliably, and can effectively ensure conveyance capacity, reduces potential safety hazard.

The technical scheme that the utility model solves its technical problem employing is: terminal is provided with conductor crimping district and insulation riveting district, the insulated hull subsection setup of wire, between adjacent two sections of insulated hulls, it is exposed metal core, the conductor crimping district of terminal rolls and encases metal core, and insulation riveting district at least coordinates with one section of insulated hull riveting. Conductor crimping district contacts with metal core and not excessively compressing, avoid plain conductor to affect conveyance capacity because of deformation, and conductor crimping district is clipped between the insulated hull of two ends, can improve the firmness coordinating between terminal and wire by the adhesive force between insulated hull and metal core.

An example of the present utility model is that the cross section in described conductor crimping district is annular. The rolling of conductor crimping district circularizes, and is conducive to ensure the roundness of metal core, forms the conveyance capacity ensureing between wire and terminal, reduces potential safety hazard.

An example of the present utility model is that the cross section in described insulation riveting district is down the B font of side. Insulation riveting district riveting becomes B font to be conducive to the tautness that ensures that terminal coordinates with wire.

An example of the present utility model is that the insulated hull of described wire is two sections, coordinates with insulation riveting district riveting near one section of insulated hull of terminal.

Various examples above, both can, separately as an embodiment, also can ensure under reconcilable prerequisite, each example any combination forms combined type embodiment.

Detailed description of the invention

Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish. Exemplary below by the embodiment being described with reference to the drawings, only for explaining the utility model, and can not be interpreted as restriction of the present utility model, on the contrary, embodiment of the present utility model comprises all changes, amendment and the equivalent within the scope of spirit and the intension that falls into additional claims.

As shown in Fig. 1 (a) and Fig. 2 (a), the present embodiment terminal 1 is provided with conductor crimping district 11 and insulation riveting district 12, and the insulated hull 21 of wire 2 is divided into two sections of settings, is exposed metal core 22 between two sections of insulated hulls 21. Before terminal 1 is connected with wire 2, the cross section in conductor crimping district 11 and insulation riveting district 12 is U-shaped, as shown in Fig. 1 (b) and Fig. 1 (c).

By wire 2 near one section of insulated hull 21 of terminal 1 be placed in insulation riveting district 12, metal core 22 is placed in conductor crimping district 11, makes it fixing with special frock clamp. As shown in Fig. 2 (a) and Fig. 3, after terminal 1 is connected and fixed with wire 2, conductor crimping district 11 rolls, and its ring-shaped section and ring-shaped encases metal core 22, to guarantee the roundness of metal core 22, as shown in Fig. 2 (b). Meanwhile, after insulation riveting district 12 rivetings, cross section is down the B font of side, as shown in Figure 2 (c).

In the present embodiment, after terminal 1 is connected with wire 2, the diameter of wire 2 metal cores 22 is consistent or approaches consistent with the diameter that does not connect front metal core 22, this can not only effectively ensure conveyance capacity, reduce the temperature rise that link position causes because crimping is bad, and used under the wire diameter of similarity condition, reduced the material that uses reinforced insulation or protecting high temperature, reduce manufacturing process, provided cost savings and improved production efficiency.
