Description

Technical Field

[0001] The utility model relates to the technical field related to connecting wires, in particular to a single-branch wire hook welding terminal. Background Art

[0002] The wire is generally connected to the PCB board by tinning. The specific connection method is that the wire core at one end is exposed, the exposed end of the wire is inserted into the through hole on the PCB board, and then the wire and the PCB board are tinned. Since there is a certain gap between the exposed wire core and the through hole on the PCB, the tin liquid will fall off when tinning at the connection position between the two. After the tin liquid falls off, it needs to be tinned again, affecting production efficiency; in addition, the wire may float up during tinning, causing the wire core to be exposed too much, causing the product to be scrapped, resulting in a high defective rate. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of the utility model is to provide a single-wire hook welding terminal to solve the above technical problems.

[0004] The technical solution adopted by the utility model to solve the technical problem is as follows:

[0005] According to one aspect of the utility model, a single-wire hook welding terminal is designed, comprising: a wire body, the end of the wire body having a bare wire core, a connector fixedly connected to the bare wire core, and at least one elastic barb is provided on the connector.

[0006] By adopting the above technical scheme, a connector is fixedly connected to the exposed core of the conductor body, and an elastic barb is arranged on the connector. When the end of the conductor body is connected to the PCB board, one end of the conductor body with the elastic barb passes through the through hole on the PCB board. When passing through the through hole, the elastic barb is squeezed and gathered close to the exposed core. After passing through the through hole, the elastic barb automatically opens and resets. When tin liquid is applied to the connection position between the exposed core and the PCB board, the elastic barb is located at the lower position of the PCB board to support the tin soldering liquid flowing down from the gap between the exposed core and the through hole on the PCB, preventing the tin soldering liquid from falling off, completing the tinning at one time, and improving the production efficiency. In addition, the elastic barb can also prevent the conductor body from floating up during tinning, that is, the conductor body moves up, preventing the upper part of the exposed core from being exposed too much, and improving the qualified rate of the product.

[0007] In order to better solve the above technical defects, the utility model also has a better technical solution:

[0008] In some embodiments, the two ends of the wire body respectively have exposed wire cores, the connector is fixedly connected to the exposed wire core at one end of the wire body, and a connection terminal is fixedly connected to the exposed wire core at the other end.

[0009] In some embodiments, the two ends of the wire body have exposed wire cores respectively, the exposed wire cores at both ends of the wire body are fixedly connected to the connecting pieces, and elastic barbs are provided on the two connecting pieces.

[0010] In some embodiments, the connecting piece is made of metal and is C-shaped or circular.

[0011] In some embodiments, the elastic barb and the connecting piece are an integral structure, and two elastic barbs are provided in a symmetrical structure.

[0012] In some embodiments, the elastic barb and the connecting member are an integral structure, and three or four elastic barbs are provided and evenly distributed around the circumference.

[0013] In some embodiments, the connector and the elastic barb are provided with a chrome coating.

[0014] In some embodiments, an insulating rubber sleeve is sleeved on the connection position between the wiring terminal and the wire body. BRIEF DESCRIPTION OF THE DRAWINGS
