For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0046] Example 1

[0047] like Figures 2 to 5 As shown, this embodiment discloses an elastic wire clamping structure, including a spring-type wire clamping terminal 1 and a plug-in terminal 2. The spring-type wire clamping terminal 1 includes a positioning section 11, an extrusion section 12 and a clamping section 13 connected in sequence, and an unclosed extrusion ring is formed between the positioning section 11 and the extrusion section 12, and a first convex plate 15 is provided at the end of the positioning section 11 that is not connected to the extrusion section 12. The plug-in terminal 2 is connected to the positioning section 11, and a positioning hole 23 is opened on the plug-in terminal 2, and the first convex plate 15 is fitted in the positioning hole 23. A wire insertion position is formed between the positioning section 11 and the plug-in terminal 2, that is, when the wire is inserted into the wire insertion position and the spring-type wire clamping terminal 1 is not squeezed, the wire can be locked, and when the spring-type wire clamping terminal 1 is squeezed, the wire insertion position expands, and the wire can be taken out at this time.

[0048] The above-mentioned elastic wire clamping structure can directly embed the first protruding plate 15 of the spring-type wire clamping terminal 1 into the positioning hole 23 of the plug-in terminal 2 when positioning between the spring-type wire clamping terminal 1 and the plug-in terminal 2, thereby strengthening the connection strength between the spring-type wire clamping terminal 1 and the plug-in terminal 2, making the assembly of the spring-type wire clamping terminal 1 and the plug-in terminal 2 more secure and preventing loosening.

[0049] In this embodiment, the spring-type clamping terminal 1 is designed with a first protrusion 15 (small protrusion) embedded in the plug-in terminal. Regardless of the stress of the spring-type clamping terminal or the number of life tests, the spring-type clamping terminal is firmly clamped in the plug-in terminal, which is safe and reliable.

[0050] In some embodiments, a through hole 14 is provided on the extrusion section 12, and the positioning section 11 moves through the through hole 14 and has a spacing with the through hole 14 along the extrusion direction. In this embodiment, when the spring-type clamping terminal 1 is squeezed by an external force, the positioning section 11 does not move, and the extrusion section 12 can move along the length direction of the through hole, so that the spring-type clamping terminal 1 can change its shape when squeezed. When the spring-type clamping terminal 1 is not subjected to an external force, the spring-type clamping terminal 1 will return to its original position due to its own elastic force.

[0051] In some embodiments, the first convex plate 15 is disposed at the end of the positioning section 11 extending out of the through hole 14, and the portion of the positioning section 11 extending out of the through hole 14 and the first convex plate 15 are bent toward the direction of the plug-in terminal 2. In this embodiment, because the portion of the positioning section 11 extending out of the through hole 14 and the first convex plate 15 are arranged in a bent shape, the first convex plate 15 is more easily positioned inside the positioning hole 23, thereby enhancing the assembly tightness of the spring-type clamping terminal 1 and the plug-in terminal 2.

[0052] In some embodiments, the plug terminal 2 includes a plug terminal body 21 and a positioning plate 22. The plug terminal body 21 is suitable for being positioned inside the housing 3. The positioning plate 22 is integrally arranged on the top of the plug terminal body 21, and the length of the positioning plate 22 is less than the length of the plug terminal body 21. The positioning plate 22 passes through the through hole 14, and the positioning hole 23 is opened on the positioning plate 22.

[0053] In some embodiments, a second convex plate 16 is provided downwardly extending from the through hole 14 of the extrusion section 12, and the second convex plate 16 is bent into a barb shape. In this embodiment, the second convex plate 16 is close to the wire 5 relative to the positioning section 11. On the one hand, the second convex plate 16 cooperates with the positioning section 11 to form a clamping position, and the positioning plate 22 can be clamped and positioned more firmly by passing through the clamping position. On the other hand, the second convex plate 16 pre-compresses and clamps the wire, and a barb structure is formed after the wire is inserted, which clamps the wire and prevents the wire from being easily pulled out.

[0054] In some embodiments, the positioning plate 22 is bent toward the positioning section 11 to better contact the end of the positioning section 11 and enable the first protrusion 15 to be better clamped into the positioning hole 23, making the clamping of the spring-type wire terminal 1 and the plug-in terminal 2 more secure.

[0055] In some embodiments, at least one elongated hole 24 is provided on the side wall of the plug terminal body 21 opposite to the wire, and the elongated hole 24 is suitable for increasing the friction between the wire and the plug terminal body 21. The inner side wall of the elongated hole 24 can be an inclined side wall to further increase the friction between it and the plug terminal body 21, making it easier to clamp the wire.

[0056] In some embodiments, a third convex plate 25 is provided on the side wall of the plug terminal body 21 opposite to the wire. In this embodiment, the third convex plate 25 protrudes from top to bottom, and the third convex plate 25 pre-compresses the wire. After the wire is inserted, a barb structure is formed to clamp the wire, and the wire is not easily pulled out.

[0057] The wiring process of the wire of the utility model is as follows: insert the wire into the wire insertion position formed between the clamping section 13 and the plug-in terminal 2. After the wire is inserted, the clamping section 13 of the spring-type clamping terminal 1 shrinks and moves toward the plug-in terminal 2 to clamp the wire, and the bosses on the spring-type clamping terminal 1 and the plug-in terminal 2 form barbed structures respectively, which form a more firm and stable contact with the wire, and the wire is not easy to be pulled out. The spring-type clamping terminal 1 is embedded in the plug-in terminal 2, and the spring-type clamping terminal 1 is firmly and tightly assembled without loosening.

[0058] Example 2

[0059] like Figure 6 As shown, this embodiment discloses a quick wiring mechanism, including a housing 3, a toggle structure 4 and an elastic wire clamping structure of embodiment 1. The housing 3 has at least one wire insertion hole 31 suitable for inserting a wire 5. The elastic wire clamping structure is arranged on the housing 3, and has an unlocked state and a locked state; when the elastic wire clamping structure is in the unlocked state, the elastic wire clamping structure provides a reserved space for the wire 5, and the reserved space is suitable for allowing the wire to be inserted into the housing 3 from the wire insertion hole 31; when the elastic wire clamping structure is in the locked state, the elastic wire clamping structure is suitable for squeezing the wire 5 inserted into the housing 3 to lock the wire 5. A part of the toggle structure 4 is arranged inside the housing 3 and abuts against the elastic wire clamping structure, and another part of the toggle structure 4 extends out of the housing 3, and the toggle structure is suitable for controlling the switching of the unlocked state and the locked state of the elastic wire clamping structure.

[0060] This embodiment uses the toggle structure 4 extending out of the housing to control the operating state of the elastic wire clamping structure, which is convenient for operators to operate. The movement of the toggle structure 4 drives the elastic wire clamping structure to move, and the elastic wire clamping structure squeezes the wire to achieve the locking function of the wire. Compared with the traditional method of locking the wire with screws, the utility model does not require any wiring tools. The operator only needs to drive the toggle structure 4 to achieve the locking of the wire. Ordinary family members can easily connect the wires, which improves the wiring efficiency and saves labor.

[0061] It should be noted that the housing 3 in this embodiment can be a socket housing or other product housings, and this embodiment can be applied to socket products, but is not limited to socket products. When the housing 3 is a socket housing, the plug-in terminal 2 is a socket terminal.

[0062] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
