Description

Technical Field

[0001] The utility model relates to the technical field of wiring terminals, in particular to a solder-free wiring terminal. Background Art

[0002] The terminal block is a conductive component used to electrically connect a wire to a circuit board, such as connecting the end of the enameled wire in a motor coil to a circuit board. When the terminal blocks currently used on the market are connected to the end of the enameled wire, it is usually necessary to clamp the end of the enameled wire with the wire clamp of the terminal block, and then melt the lacquer layer of the enameled wire by high-temperature heating to expose the wire core and electrically connect it to the wire clamp of the terminal block. This method requires heating the connection, which is cumbersome and inefficient to operate, and it is difficult to achieve a quick connection. In addition, when these terminal blocks are plugged into the conductive sockets of the circuit board, due to the disadvantage of poor resistance to plastic deformation, the terminal blocks and the conductive sockets are prone to loosening or detachment, which in turn affects the reliability of the electrical connection between the terminal blocks and the circuit board. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a connection terminal which can be quickly installed and does not require soldering.

[0004] The technical solution of the utility model is to provide a solder-free terminal block with the following structure:

[0005] It includes a terminal body, a plug connector is provided at the top of the terminal body, and a wire clamp is provided on one side wall of the terminal body; the plug connector is shuttle-shaped and has a cavity inside for being plugged into a conductive socket; the wire clamp is provided with a puncture groove, and the wire clamp is used to clamp the enameled wire and puncture the paint coating of the enameled wire through the puncture groove.

[0006] After adopting the above structure, the solder-free terminal of the utility model has the following advantages compared with the prior art:

[0007] The utility model provides a wire clamping piece on one side wall of the terminal body and a puncture groove on the wire clamping piece. When the wire clamping piece clamps the end of the enameled wire, the lacquer layer of the enameled wire is punctured through the puncture groove and electrically connected to the wire core in the enameled wire. There is no need to melt the lacquer layer of the enameled wire at high temperature. The operation is simple, convenient and efficient. In addition, the plug connector is configured to be a shuttle with a cavity inside, which can improve the plug connector's resistance to plastic deformation, so that after the plug connector and the conductive socket are plugged in, the firmness of the wiring terminal and the conductive socket after plugging in can be improved, and the reliability of the electrical connection between the wiring terminal and the conductive socket can be improved.

[0008] Preferably, the cavity of the plug connector passes through its two side walls, and the two side walls form open ends. This arrangement is not only convenient for processing, but also reduces materials and costs while ensuring its ability to resist plastic deformation.

[0009] Preferably, an elastic block is provided in the cavity, and the upper and lower ends of the elastic block are respectively connected to the top wall and the bottom wall of the cavity through connecting blocks. The elastic block can further improve the plastic deformation resistance of the plug connector and prevent it from being over-extruded and deformed and unable to recover.

[0010] Preferably, a cut surface is provided at the top of the plug connector to facilitate the insertion of the plug connector into the conductive socket.

[0011] Preferably, the plug connectors are multiple and spaced apart along the length direction of the top of the terminal body. The cooperation of multiple plug connectors and the conductive socket can increase the conducting cross-sectional area between the terminal and the circuit board, thereby increasing the current carrying capacity.

[0012] Preferably, there are two wire clamping pieces, and one side wall of the two wire clamping pieces is connected to form a wire clamping groove for clamping the enameled wire.

[0013] Preferably, the piercing groove comprises a plurality of tooth grooves spaced apart along the length direction of the clamping piece, and the tooth grooves on the two clamping pieces mesh with each other. By squeezing the two clamping pieces together, the enameled wire can be clamped and the enameled wire can be easily pierced by the meshing tooth grooves.

[0014] Preferably, a plug-in portion is provided at the lower end of the terminal body for plugging into the plastic shell cavity. BRIEF DESCRIPTION OF THE DRAWINGS
