Description

Technical Field

[0002] Phoenix terminals are commonly used electrical interface components, widely applied in circuit connection scenarios. They offer advantages such as convenient wiring, high safety, strong compatibility, and improved work efficiency.

[0003] Patent application number 201922357460.0 discloses a wire lug, comprising: a crimping assembly having a crimping space for positioning the wire core; and a sealing assembly connected to the crimping assembly to seal at least a portion of the wire core within the crimping space when the crimping assembly positions the wire core. This wire lug solves the problem of unsafe crimping of wire cores in existing technologies.

[0004] Those skilled in the art have found in actual use of Phoenix terminals that existing wire lugs are not well adapted to Phoenix terminals for wire connection. If Phoenix terminals are used to connect directly to wires, in situations involving swaying or shaking, the conventional method of directly inserting the conductive part of the wire into the Phoenix terminal can cause the conductive part of the wire to sway, leading to metal fatigue and easy breakage, thus affecting the product's lifespan. Utility Model Content

[0005] In view of the above-mentioned problems in the prior art, the main purpose of this utility model is to provide a wire head connection device that can be used with Phoenix terminals to reduce metal fatigue, reduce the risk of breakage, and improve the service life of the product.

The interlocking structure includes at least two rows of protrusions arranged parallel to each other and at equal intervals along the circumferential direction of the inner wall of the C-shaped tube. The interlocking structure, the anti-slip structure and the C-shaped tube are integrally stamped and formed and are made of copper. The interlocking structure and the anti-slip structure protrude from the inner wall of the C-shaped tube at the same height.

[0007] Furthermore, the protrusion is a tetrahedron, a trihedron, or a triangular prism.

[0008] Furthermore, the anti-slip structure includes several geometric shapes arranged parallel to each other along the circumferential direction of the inner wall of the C-shaped tube.

[0009] Further, the geometric body is a triangular strip or a sawtooth strip.

[0010] Further, the outer wall of the C-shaped pipe body is provided with a resistance increasing structure.

[0011] Further, the resistance increasing structure is a plurality of recesses arranged on the outer wall of the C-shaped pipe body.

[0012] Preferably, the recesses are a plurality of parallel recesses arranged along the torus direction of the outer wall of the C-shaped pipe body.

[0013] Preferably, the recesses are a plurality of parallel recesses arranged along the length direction of the C-shaped pipe body.

[0014] Preferably, the recesses are meshed recesses arranged along the torus direction and the length direction of the outer wall of the C-shaped pipe body.

[0015] Further, the resistance increasing structure is a plurality of convex points arranged in a matrix on the outer wall of the C-shaped pipe body.

[0016] Compared with the prior art, the utility model has the beneficial effects that the utility model is used in cooperation with the wire and is plugged into the phoenix terminal jack, the occlusion structure can connect the conductive part of the wire and the utility model firmly, the anti-skid structure can increase the friction between the conductive part and the utility model to prevent slipping, the resistance increasing structure can increase the friction when the utility model is plugged into the phoenix terminal jack to prevent shaking and swinging, thereby slowing down the occurrence of metal fatigue, reducing the probability of breaking, and improving the service life of the product.

[0022] In order to make the purpose, technical scheme and advantages of the utility model embodiment clearer, the technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Embodiment

[0023] As shown in Figs. 1 to 4 A wire head connecting device comprises a C-shaped pipe body 1 with a certain length, a clamping structure 2 located on the inner wall of the C-shaped pipe body 1 and close to both ends, and an anti-skid structure 3 located on the inner wall of the C-shaped pipe body 1 and between the two clamping structures 2. The clamping structure 2 comprises at least two rows of convex blocks 21 arranged in parallel and at equal distances along the toroidal direction of the inner wall of the C-shaped pipe body 1. The clamping structure 2 and the anti-skid structure 3 are integrally stamped with the C-shaped pipe body 1 and are made of copper. The height of the clamping structure 2 protruding from the inner wall of the C-shaped pipe body 1 is the same as that of the anti-skid structure 3.

[0024] The convex block 21 is a four-sided pyramid, a three-sided pyramid or a triangular body.

[0025] The outer wall of the C-shaped pipe body 1 is provided with a resistance increasing structure 4.

[0026] In use, the insulating layer of the wire is peeled off, and then the conductive part of the wire is folded outward toward the insulating layer of the wire so as to be attached to the insulating layer of the wire from the outside. Subsequently, the utility model is sleeved on the conductive part and clamped by a pair of pliers. Since the convex block 21 is a four-sided pyramid, a three-sided pyramid or a triangular body with a sharp end, the conductive part can be tightly pressed against the insulating layer of the wire, thereby ensuring firm connection, so that the utility model is firmly connected with the wire to form a whole.

[0027] Then the utility model is inserted into the phoenix terminal jack. Since the clamping structure 2 firmly connects the conductive part of the wire with the utility model, and the anti-skid structure 3 can increase the friction between the conductive part and the utility model to prevent slipping, and the resistance increasing structure 4 can increase the friction when the utility model is inserted into the phoenix terminal jack to prevent shaking and swinging, thereby slowing down the occurrence of metal fatigue, reducing the probability of breakage, and improving the service life of the product. Embodiment

[0029] The geometric body 31 is a triangular strip or a sawtooth strip.

[0030] The resistance increasing structure 4 is a plurality of grooves 41 arranged on the outer wall of the C-shaped pipe body 1.

[0031] The grooves 41 can be designed as a plurality of parallel grooves 41 arranged along the torus direction of the outer wall of the C-shaped pipe body.

[0032] Or as a plurality of parallel grooves 41 arranged along the length direction of the C-shaped pipe body.

[0033] Or as a mesh-shaped groove 41 arranged along the torus direction and the length direction of the outer wall of the C-shaped pipe body. Embodiment

[0034] As shown in Figs. 3 to 4 As another preferred solution of Embodiment 1, the resistance-increasing structure 4 is a plurality of convex points 42 arranged in a matrix on the outer wall of the C-shaped pipe body 1.

[0035] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
