Detailed Description

As shown in fig. 1-5, a jointing clamp includes a clamp body 1, an insertion hole 2 for inserting a wire is provided at an end of the clamp body 1, a cavity chamber 3 is provided in the clamp body 1, a clamping member 4 and a conductive member 5 are provided in the cavity chamber 3, and the cavity chamber 3 is communicated with the insertion hole 2. The clamp body 1 is further provided with a connector testing hole, which is not described herein. The wire is inserted into the clamp body 1 from the jack 2, goes deep to the cavity chamber 3, and is electrically connected through the conductive piece 5, and the clamping piece and the conductive piece 5 play a clamping effect together.

Clamping piece 4 has last stiff end 6, elasticity portion 7 and colludes even end 8 on with, electrically conductive piece 5 has down stiff end 9, conductive part 10 and colludes even end 11 down, cavity chamber 3 leans on being equipped with on 2 one side lateral walls of jack and inlays hole 12 and inlay hole 13 down, go up stiff end 6 and inlay between the hole 12 on, down stiff end 9 and inlay the socket joint formula cooperation between the hole 13 down, and clamping piece 4 and electrically conductive piece 5 restrict the wire through last stiff end 6 and stiff end 9 down respectively and draw reversely. The upper embedding hole 12 and the lower embedding hole 13 are arranged at the inlet of the lead of the cavity chamber 3, which prevents the reverse drawing of the lead, and simultaneously plays a certain protection role for the clamping piece and the conductive piece 5, and avoids the drawing to make the clamping piece and the conductive piece separate from each other.

The clamping piece 4 and the conductive piece 5 form a seamless assembly through an upper hooking end 8 and a lower hooking end 11, and the clamping piece 4 is made of an elastic material. At the beginning, the upper hooking end 8 and the lower hooking end 11 are mutually abutted or mutually staggered and abutted with other parts. This point enables a seamless structure that slightly blocks the insertion of the wire, facilitating a greater and stable clamping force on the wire thereafter.

A positioning hole 14 is arranged between the jack 2 and the cavity chamber 3, the front end of the lead is clamped and fixed by the clamping piece 4 and the conductive piece 5, and the rear end of the lead is limited and fixed by the positioning hole 14 with similar size. Through two-point positioning and fixing, the connection stability is greatly improved.

The diameter of the jack 2 is gradually reduced from outside to inside, so that smooth insertion of the wires is facilitated, and the wire collecting and guiding effects are achieved.

An included angle is formed between the upper hooking end 8 and the elastic part 7, and an included angle is formed between the lower hooking end 11 and the conductive part 10. The clamping piece 4 and the conductive piece 5 are of a fold line structure, and the upper hooking end 8 and the lower hooking end 11 are bent oppositely. Similar to a hook shape, ensures smooth insertion of the wire and a corresponding stable clamping force.

The clamp body 1 consists of a base 15 and a clamping cover 16, and the base 15 and the clamping cover 16 are fixedly assembled. The split structure is beneficial to assembly and improves production efficiency, and a clamping fixing structure or a threaded connection structure can be arranged between the base 15 and the clamping cover 16, so that the practical production is the standard, and the description and the limitation are not excessive.

Elastic part 7 and collude even end 8 on and be equipped with a plurality ofly along 6 width extending direction on the stiff end, make things convenient for stranded conductor to insert, clamping piece 4 can be simultaneously and stable centre gripping stranded conductor simultaneously.

The lower hooking ends 11 are arranged along the width extension direction of the conductive part 10, and the application range and the use stability can be improved in the same way.

The outer walls of the upper embedding hole 12 and the lower embedding hole 13 are provided with reinforcing ribs 17, when the embedding holes are exposed and are not completely integrated into the clamp body 1 and flush with the surface of the clamp body, wires are easy to be damaged for a long time, and therefore the reinforcing ribs 17 are designed to increase structural strength.

The diameter of the positioning hole 14 is smaller than that of the insertion hole 2, and the wire has gradation or steps in the axial direction, so that the wire is prevented from being excessively inserted through the positioning hole 14.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, and are only for convenience of description, and are not intended to indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific orientation, and therefore, are not to be considered as limitations of the present invention, and the fundamental principles, main features, and advantages of the present invention have been shown and described above, as would be understood by those skilled in the art.
