Description
Technical Field
[0001] The utility model relates to the technical field of wire connection, in particular to a wire connection structure and a quick-acting switch. Background Art
[0002] Many electrical products in the prior art, such as snap-action switches, require the use of wires, which are electrically connected to corresponding conductive parts in the electrical products (such as static springs of snap-action switches, etc.) to supply power to the conductive parts. At present, the connection methods of the wires and the conductive parts mainly include the following two methods: one is that a notch is provided on the conductive part, and the wire core head at one end of the wire is electrically connected to the conductive part at the notch; the other is that the wire core head at one end of the wire is directly electrically connected to the surface of the conductive part. The above two wire connection methods both have the following shortcomings: when the wire is pulled or twisted by external force, the connection between the wire and the conductive part is easy to disengage or produce a gap, resulting in unreliable connection. In order to solve the above problems, some prior art will additionally set up a wire fixing sleeve for further positioning the wire. However, the use of an additional wire fixing sleeve not only increases the cost, but also increases the assembly process of the wire fixing sleeve. Utility Model Content
[0003] The utility model aims at the technical problems existing in the prior art and provides a wire connection structure and a quick-acting switch, which can solve the problem of unreliable connection caused by external pulling or twisting of the wire without adding a wire fixing jacket.
[0004] The utility model adopts the following technical solution to solve the technical problem: a wire connection structure, comprising a wire and a conductive part, wherein the wire comprises a conductive core and an insulating layer wrapped around the conductive core, and a core head at one end of the conductive core is electrically connected to the conductive part; the conductive part is provided with a wire clamping opening, which clamps the end of the insulating layer corresponding to the core head.
[0005] Furthermore, the wire clamping opening is in the shape of a notch, and a protrusion capable of pressing against the insulating layer is provided on the inner wall of the wire clamping opening.
[0006] Furthermore, the number of the protrusions is two, and the two protrusions are located on two opposite sides of the wire clamping port and are arranged opposite to each other; the protrusion is an inverted structure that can pierce the insulating layer.
[0007] Furthermore, the conductive member is also provided with a core clamping opening, which clamps the wire core head.
[0008] Furthermore, the clamping core opening is in a notch shape, and at least one side of the clamping core opening can be elastically deformed to clamp the wire core head.
[0009] Furthermore, limiting protrusions are respectively provided at both ends of the core opening to limit the wire core head from exiting from an opening formed between the two ends of the core opening.
[0010] Furthermore, the conductive member is connected to the wire core head by soldering, and the solder material formed by soldering is located at an opening formed between two ends of the clamping core opening.
[0011] Furthermore, the wire clamping opening and the core clamping opening are arranged in parallel, and the wire core head is in a bent shape.
[0012] Furthermore, a plurality of hollow holes for reducing heat conduction are provided at the portion where the conductive member is connected to the wire, and one of the hollow holes is in the shape of a notch and is close to the card core opening.
[0013] The utility model further provides a snap-action switch, comprising the wire connection structure as described in the utility model, wherein the conductive member is a static spring of the snap-action switch.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] 1. Since the utility model has a wire clamping opening on the conductive part, the wire clamping opening clamps the end of the insulating layer corresponding to the wire core head, so that the utility model can use the wire clamping opening of the conductive part to further position the wire, thereby solving the problem of unreliable connection between the wire and the conductive part when the wire is pulled or twisted by external force. In particular, the utility model directly sets the wire clamping opening on the conductive part, so that the utility model does not need to set up a wire fixing jacket separately, which is conducive to reducing costs and simplifying the assembly process of the product.
[0016] 2. The wire clamping opening is in the shape of a notch, which is convenient for the insulating layer of the wire to be clamped therein. In particular, a protrusion that can press against the insulating layer is provided on the inner wall of the wire clamping opening, which can further improve the clamping degree of the wire clamping opening on the insulating layer.
[0017] 3. The protrusion is an undercut structure capable of piercing the insulating layer, which can further improve the clamping degree of the wire clamping port on the insulating layer.
[0018] 4. The conductive part of the utility model is further provided with a clamping core opening, which clamps the wire core head of the wire, making the electrical connection between the wire and the conductive part simpler and more reliable. In particular, the two ends of the clamping core opening are respectively provided with limiting convex parts, which can limit the wire core head from exiting from the opening formed between the two ends of the clamping core opening, and can scrape the wire core, which can increase the soldering qualification rate when using the soldering process.
[0019] 5. The conductive part is also provided with hollow holes, which reduces the local cross-sectional area of the conductive part, thereby effectively reducing heat conduction and increasing the soldering pass rate. In particular, at least one hollow hole is in the shape of a notch and is close to the core opening, which can improve the elastic deformation capacity of the core opening.
[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments; however, the wire connection structure and the snap-action switch of the utility model are not limited to the embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1-Figure 5 As shown, a wire connection structure of the utility model includes a wire 1 and a conductive member 2, wherein the wire 1 includes a conductive wire core 12 and an insulating layer 11 covering the conductive wire core 12, and a wire core head 121 at one end of the conductive wire core 12 is exposed outside the insulating layer 11 and is electrically connected to the conductive member 2. The conductive member 2 is provided with a wire clamping opening 21, and the wire clamping opening 21 clamps one end of the insulating layer 11 corresponding to the wire core head 121.
[0028] In this embodiment, the wire clamping opening 21 is in the shape of a notch, and a protrusion 211 capable of pressing against the insulating layer 11 is provided on the inner wall of the wire clamping opening 21. Figure 2 As shown, there are two protrusions 211, which are located on opposite sides of the wire-holding opening 21 and are arranged opposite to each other. Each protrusion 211 is an undercut structure capable of piercing the insulating layer 11. In other embodiments, the wire-holding opening is in the shape of a through hole.
[0029] In this embodiment, the conductive member 2 is further provided with a core opening 22, and the core opening 22 is used to clamp the wire core head 121. Figure 3 As shown. Figure 2 As shown, the clamping core opening 22 is in the shape of a notch, and at least one side of the clamping core opening 22 can be elastically deformed to clamp the core head 121. In addition, limiting protrusions 221 are respectively provided at both ends of the clamping core opening 22 to limit the core head 121 from exiting from the opening formed between the two ends of the clamping core opening 22. On the basis of the clamping core opening 22 clamping the core head 121, the core head 121 can be further connected to the conductive member 2 by soldering, and the solder material 3 formed by soldering is located at the opening formed between the two ends of the clamping core opening 22, as shown in FIG. Figure 4 As shown. The setting of the core opening 22 can provide positioning when the wire core head 121 is connected to the conductive member 2 by soldering, making the soldering process easier to implement. In addition, the limiting protrusions 221 set at both ends of the core opening 22 can scrape the wire core head 121, which can increase the soldering pass rate when the soldering process is adopted. In other embodiments, the core opening is in the shape of a through hole.
[0030] The wire clamping opening 21 and the core clamping opening 22 are arranged in parallel. Specifically, the conductive member 2 is in sheet shape, and the wire clamping opening 21 and the core clamping opening 22 are distributed along the width direction of the conductive member 2. Therefore, the wire core head 121 is bent and roughly forms a U shape with one end of the insulating layer 11.
[0031] The portion where the conductive part 2 of the utility model is connected to the wire 1 is also provided with a plurality of hollow holes for reducing heat conduction, and one of the hollow holes 23 is in the shape of a notch and is close to the card core opening 22. Specifically, the opening of the notch-shaped hollow hole 23 and the opening of the card core opening 22 are located on adjacent sides of the conductive part 2, and the opening directions of the two are perpendicular to each other, so that the conductive part 2 forms a relatively independent clip 25 with good elastic deformation ability at the portion between the card core opening 22 and the hollow hole, and the clip 25 corresponds to one side of the card core opening 22, so that the elastic clamping ability of the card core opening 22 is better. The number of hollow holes is specifically two, but not limited to this. The other hollow hole 24 is a waist-shaped hole, and is arranged along the width direction of the conductive part 2.
[0032] The utility model provides a wire connection structure, wherein the wire clamping opening 21 can clamp one end of the insulating layer 11, and the protrusion 211 on the wire clamping opening 21 pierces the insulating layer 11, thereby increasing the clamping degree of the wire clamping opening 21 on the insulating layer 11, so that the wire clamping opening 21 of the conductive member 2 can firmly clamp one end of the insulating layer 11. When the wire 1 is pulled or twisted by an external force, the clamping force between one end of the insulating layer 11 and the wire clamping opening 21 can offset these external forces and will not be transmitted to the wire core head 121, so that the wire core head 121 of the wire 1 can be firmly matched with the clamping opening 22 of the conductive member 2, thereby preventing the wire core head 121 from being disengaged from the conductive member 2 or generating a gap. In particular, the utility model directly uses the wire clamping opening 21 of the conductive member 2 to clamp the insulating layer 11 of the wire 1, thereby solving the problem of unreliable connection when the wire 1 is pulled or twisted by an external force, so that the utility model does not need to set up a wire fixing jacket separately, thereby helping to reduce costs and simplify the assembly process of the product.

[0034] The utility model is a snap-action switch. For the wire connection structure and the construction and connection principle of the snap-action switch, please refer to the above description, which will not be repeated here.
[0035] The utility model provides a wire connection structure and a quick-acting switch, and the unrelated parts are the same as the prior art or can be implemented by using the prior art.
[0036] The above embodiments are only used to further illustrate a wire connection structure and a quick-acting switch of the utility model, but the utility model is not limited to the embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model fall within the protection scope of the technical solution of the utility model.
