Abstract

The utility model relates to a bundle wire end-part clamping device. A plurality of wire cores are arranged at the end part of a bundle wire, wire skins of the wire cores are exposed, the wire cores are bundled together by a metal clamp, and a protection device used for assisting in clamping is further arranged outside the metal clamp. The protection device comprises an upper cover and a lower cover which are made of insulation materials, openings of the upper cover and the lower cover are butt-jointed to form a hollow cylinder body, a convex ring is arranged at the front end of the cylinder body, the convex ring is clamped on a locking arm of the metal clamp, and the rear part of the cylinder body is tightly wrapped outside the wire skins. The clamping device realizes the clamping protection of the metal clamp mainly by utilizing the upper cover and the lower cover which are made of the insulation materials; and the traditional protection structure of a thermal shrinkable sleeve is replaced. Relatively speaking, the clamping device achieves better insulating protection effect; meanwhile, the butt-jointing and detaching operations between the upper cover and the lower cover are simple as well as easy, the assembling and repairing are convenient, and the clamping device is beneficial for increasing the producing as well as assembling efficiency and reducing the cost.

Description

Bunch end clamping device

Technical field

The utility model relates to the bunch of electric equipment and ties up the connection area technology, refers in particular to the bunch end clamping device that a kind of production and assembly are convenient, have preferable insulation effect.

Background technology

In electronic machines ﹠ apparatus, usually need the core of bunch is carried out the bundling type connection.With reference to shown in Figure 1; its bunch that has demonstrated tradition is tied up the structure when connecting; it substantially all is that the core 12 that by a metal clip 20 the outlet skin is exposed in bunch 10 ends earlier bands together; and then cover is loaded onto a heat-shrinkable T bush 40; utilize this heat-shrinkable T bush 40 to encircle metal clip 20; play on the one hand the effect that the locking arm 21 that prevents metal clip 20 unclamps, can be used for the insulation protection of core 12 on the other hand.Yet, find that in actual production assembling the protection structure of this kind thermal shrinkable sleeve tubular type still has many weak points: the size Control difficulty of heat-shrinkable T bush 40 at first, bring the trouble in the assembling; Secondly packaging technology is more loaded down with trivial details, and it need assemble and heat two procedures, and man-hour is longer, inefficiency, and also the heat-shrinkable T bush after shrinking is difficult for taking apart, reprocesses difficulty; Moreover heat-shrinkable T bush 40 is thinner, has the hidden danger in the insulation.

The utility model content

In view of this, the utility model is at the disappearance of prior art existence, and its main purpose provides the bunch end clamping device that a kind of production and assembly are convenient, have preferable insulation effect.

For achieving the above object, the utility model adopts following technical scheme:

A kind of bunch end clamping device; this bunch end has many cores that expose the line skin; this core is banded together by a metal clip; outside this metal clip, further be provided with an auxiliary protective device that clamps usefulness; this protective device includes loam cake and the lower cover that insulating material is made, and the open butt joint of loam cake and lower cover forms the cylindrical shell of a hollow, is provided with bulge loop in the front end of this cylindrical shell; this bulge loop is clamped on the locking arm of aforementioned metal folder, and cylindrical shell rear portion hard-pressed bale is overlying on outside the line skin.

As a kind of preferred version, one lateral margin one of described loam cake and lower cover is connected, one is extended turnover brace on another lateral margin of lower cover, be provided with in this brace and collude groove, another lateral margin outer surface corresponding to loam cake is provided with raised line, when loam cake docked with lower cover, this colluded the groove snap close on this raised line.

As a kind of preferred version, on the both side edges of described lower cover respectively one extend turnover brace, be provided with in this brace and collude groove, be respectively arranged with raised line on the both side edges outer surface corresponding to this loam cake, when loam cake docked with lower cover, this colluded the groove snap close on this raised line.

After the utility model adopts technique scheme; its beneficial effect is; the clamping protection that loam cake that utilization is made by insulating material and lower cover are realized metal clip; the protection structure that has replaced the heat-shrinkable T bush of tradition comparatively speaking, the utlity model has better insulation protection effect; the butt joint of loam cake and lower cover simultaneously and take that operation is simple apart; assemble and reprocess conveniently, help improving production and assembly efficient, reduce cost.

Come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment:
