Description

Technical Field

[0001] The utility model relates to the field of circuit components, in particular to a wire-free connecting nose. Background Art

[0002] Reference Figure 1 And Figure 2 As shown in FIGS. 1 and 2, generally, for the connection between two components, the connection ends of the two components are respectively connected to the first terminal piece 310 and the second terminal piece 320 that are electrically connected to each other through a connector 300. And the first terminal piece 310 is generally electrically connected through a wire 340 with connecting noses 330 respectively installed at both ends. Specifically, one end of the connecting nose 330 is bite-connected to the wire 340, and the other end of the connecting nose 330 is fixedly connected to the first terminal piece 310 by means of screwing. However, due to the different resistance values of the wire 340 and the connecting nose 330, the connecting nose 330 is prone to excessive heat generation due to the bite force problem, resulting in a circuit break. In addition, the crimped copper wire is prone to breakage or affect the electrical conductivity quality due to insufficient crimping, which generates copper oxide. Content of the Utility Model

[0004] To achieve the above purpose, the technical solution of the utility model is: providing a connecting nose including a nose body and an insulating protective jacket. The nose body includes multiple strip-shaped high-conductivity copper sheets that are in contact and stacked with each other. Both ends of the multiple high-conductivity copper sheets are respectively bonded and fixed to form mounting ends. The nose body forms a flexible bending part between the two mounting ends. The protective jacket is sleeved outside the flexible bending part.

[0005] Preferably, mounting holes are formed in the mounting ends.

[0006] Preferably, the protective jacket includes an insulating heat-shrinkable tube and two insulating wear-resistant tubes. The heat-shrinkable tube is sleeved outside the middle part of the flexible bending part. The two wear-resistant tubes are respectively sleeved outside the flexible bending part on the two outer sides of the heat-shrinkable tube.

[0007] Preferably, the thickness of the high-conductivity copper sheet is between 0.5 mm and 1.5 mm.

[0008] Preferably, the thickness of the high-conductivity copper sheet is 0.1 mm.

[0009] Preferably, both ends of the multiple high-conductivity copper sheets are respectively welded to form the mounting ends.

In addition, the installation end of the present utility model is directly connected to the second connection end piece of the connector, and the connector does not need to set up a connection end piece anymore, indirectly reducing the manufacturing cost of the connector.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Refer to Figures 3 to 5, the wire-free connection nose 100 of the present utility model includes a nose body 10 and an insulating protective jacket 20.

[0022] The nose body 10 includes a plurality of long strip-shaped high-conductivity copper sheets 11 that are in contact and stacked with each other. Both ends of the plurality of high-conductivity copper sheets 11 are respectively bonded and fixed to form mounting ends 111, and mounting holes 1111 are provided on the mounting ends 111. A flexible bending portion 112 is formed between the two mounting ends 111 of the nose body 10. The protective jacket 20 is sleeved outside the flexible bending portion 112. In this embodiment, both ends of the plurality of high-conductivity copper sheets 11 are respectively welded to form the mounting ends 111.

[0023] Specifically, the protective jacket 20 includes an insulating heat-shrinkable tube 21 and two insulating wear-resistant tubes 22. The heat-shrinkable tube 21 is sleeved outside the middle of the flexible bending portion 112, and the two wear-resistant tubes 22 are respectively sleeved outside the flexible bending portion 112 on the two outer sides of the heat-shrinkable tube 21.

[0024] Preferably, the thickness of the high-conductivity copper sheet is between 0.5 mm and 1.5 mm. In this embodiment, the thickness of the high-conductivity copper sheet is 0.1 mm.

[0025] When the wire-free connection nose 100 of the present utility model is in use, in combination with Figures 6 to 7 , one mounting end 111 is inserted downward through the insertion hole 431 of the insulating upper connection seat 430 of the connector 400 and bent to the bottom of the upper connection seat 430, and then the mounting end 111 is locked and fixed to the second connection end piece 420 of the connector 400 through a screw 450. The connector 400 does not need to be provided with a first connection end piece anymore. The mounting end 111 is formed by welding the ends of a plurality of high-conductivity copper sheets 11, with high strength and hardness, and is more stable during installation. And the high-conductivity copper sheets 11 are not welded to each other at the flexible bending portion 112, making the flexible bending portion 112 soft and flexible to bend, referring to Figure 8 , which is more conducive to the connection between components.

[0026] The wire-free connection nose of the present utility model does not need to connect wires, avoiding the situation that due to the different resistance values of the wires and the connection nose, the connection nose is prone to excessive heat generation due to the bite force problem and causing a circuit break, and also avoiding the situation that the copper wire is easily broken during crimping or the conductivity quality is affected due to insufficient crimping and the generation of copper oxide. In addition, the mounting end of the present utility model is directly connected to the second connection end piece of the connector, and the connector does not need to be provided with a connection end piece anymore, indirectly reducing the manufacturing cost of the connector.

[0027] The above describes the present utility model in combination with the best embodiments, but the present utility model is not limited to the disclosed embodiments above, and should cover various modifications and equivalent combinations made according to the essence of this embodiment.
