Description

Technical Field

[0001] This utility model relates to the technical field of connecting terminals, specifically a multifunctional spring connector. Background Technology

[0002] As a quick-connect connector for power transmission in home appliances, the demand for terminal blocks is gradually increasing with the increasing level of industrial automation and the increasingly stringent and precise requirements of industrial control. For example, there are applications in various fields such as compressor terminal blocks and children's rocking car switch terminal blocks. When using terminal blocks, they need to be plugged into other conductive parts, so their structure is very important and directly affects the subsequent connection method.

[0003] During the production process of springs, such as Figure 1 As shown, multiple equally spaced spring bodies 2 are typically arranged on a material strip 1. The spring bodies 2 are bent to form a connecting part 203. Later, each spring body 2 is cut to the material strip 1 to form an independent spring. However, because the slot direction of the connecting part 203 cannot be changed, the external conductive parts can only be inserted in one direction after being inserted into the connecting part. This limits the insertion method of the compressor spring. For example, a spring disclosed in patent application number 201720056007.4 has only one connecting part 203, which results in the insertion direction being limited to one direction. This ultimately affects the insertion method of the spring and makes it inconvenient to change the connection direction of the spring. Utility Model Content

[0004] The purpose of this utility model is to provide a multifunctional spring connector to solve the problem mentioned in the background art that the insertion direction of the existing spring is limited, which ultimately affects the insertion method of the spring and makes it inconvenient to change the connection direction of the spring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional spring connector strip, comprising a strip, on which one or more spring bodies are integrally formed. Each spring body includes a strip connecting portion, a wire sheath foot, a wire core foot, and a connector portion arranged sequentially. The end of the strip connecting portion away from the wire sheath foot is connected to the strip. Two insert tubes are arranged opposite each other at the end of the connector portion, forming a connector groove with both ends connected. A stop bar with a gap between it and the bottom of the connector portion is provided on the side of the insert tube away from the connector portion. A bent portion is integrally formed on the end of the connector portion away from the wire core foot. A conductive insert is integrally formed on the end of the bent portion away from the connector portion. The bent portion can be broken at any angle or cut off from the connector portion. When the bent portion is bent, the conductive insert can be inserted into the connector groove of another spring body.

[0006] Preferably, to facilitate bending and subsequent cutting, a bending groove extending along the bending line is provided on the upper surface of the bending portion, and the bending groove can serve as a cutting reference line, and the width W of the bending portion is smaller than the width W of the insertion portion.

[0007] Preferably, in order to improve the positioning effect of the external conductive components, a limiting strip is provided in the insertion slot. One end of the limiting strip is connected to the bottom of the exposed insertion part, and the other end of the limiting strip is raised and a limiting hook located outside the insertion slot is provided at the end. A snap-fit ​​protrusion is provided on the upper surface of the limiting strip.

[0008] As a preferred option, to improve overall mechanical strength, the core sheath is provided with a wire clamping ring to press down the conductor, and the wire clamping ring is provided with one or more outer ribs.

[0009] Preferably, in order to facilitate the positioning of the conductive insert, a positioning through hole that cooperates with the snap-fit ​​protrusion is provided at the conductive insert.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1:

[0026] Please see Figure 2-10This utility model provides a multifunctional spring connector strip, including a strip 1, on which one or more spring bodies 2 are integrally formed. Each spring body 2 includes a strip connecting portion 204, a wire sheath foot 201, a wire core sheath foot 202, and a connector portion 203 arranged sequentially. The end of the strip connecting portion 204 away from the wire sheath foot 201 is connected to the strip 1. Two insert tubes 2031 are arranged opposite each other at the end of the connector portion 203, forming a two-end connection between the two insert tubes 2031 and the connector portion 203. The insertion slot 2032 is open. The insertion tube 2031 is provided with a baffle 2033 on the side away from the insertion part 203, which is spaced apart from the bottom of the insertion part 203. The insertion part 203 is integrally formed with a bent part 3 at the end away from the wire core wrapping foot 202. The bent part 3 is integrally formed with a conductive insert 4 at the end away from the insertion part 203. The bent part 3 can be broken at any angle or cut off from the insertion part 203. When the bent part 3 is bent, the conductive insert 4 can be inserted into the insertion slot 2032 of another spring body 2.

[0027] In one embodiment of the present invention, in order to facilitate bending and subsequent cutting, a bending groove 301 extending along the bending line is provided on the upper surface of the bending portion 3. The bending groove 301 can serve as a cutting reference line, and the width W1 of the bending portion 3 is smaller than the width W of the insertion portion 203.

[0028] In one embodiment of the present invention, in order to improve the positioning effect of the external conductive component, a limiting strip 5 is provided in the insertion slot 2032. One end of the limiting strip 5 is connected to the bottom of the exposed insertion part 203, and the other end of the limiting strip 5 is raised and a limiting hook 6 located outside the insertion slot 2032 is provided at the end. A snap-fit ​​protrusion 501 is provided on the upper surface of the limiting strip 5. In this embodiment, by providing a limiting strip 5 with one end tilted and raised, it is possible not only to limit and snap the wire or connector inserted into the insertion slot 2032 (the external wire or connector is inserted from the insertion slot 2032) but also to provide a snap-fit ​​for the wire or connector inserted into the insertion slot 2032. Insert the end away from the limiting hook 6. Later, since the limiting hook 6 is located outside the insertion slot 2032, pressing down the limiting hook 6 will press down the entire limiting pressure strip 5, separating the limiting pressure strip 5 from the external wire or connector. This makes it easier to pull the external wire or connector out of the insertion slot 2032 later, facilitating disassembly. In addition, since the above structure has added a stop strip 2033, when the connector is inserted into the insertion slot 2032, the two upper stop strips 2033, together with the lower limiting pressure strip 5, can further limit and lock the connector in the insertion slot 2032, further preventing the connector from coming off.

[0029] In one embodiment of the present invention, to improve the overall mechanical strength, a wire clamping ring 2021 is provided on the wire core sheath 202 to press down the wire. One or more outer ribs 2022 are provided inside the wire clamping ring 2021, and the outer ribs 2022 extend along the shape of the wire clamping ring 2021. Furthermore, in this embodiment, as shown... Figure 4 The aforementioned line clamp ring 2021 has a U-shaped structure, and as shown... Figure 3 As shown, the shape of the wire sheath foot 201 is U-shaped, the height H2 of the wire sheath foot 201 is 5.1±0.2mm, the distance between the openings of the wire sheath foot 201 is 5±0.2mm, and the height H3 of the wire pressure ring 2021 is 3.4±0.2mm. In this embodiment, by providing three outer ribs 2022 on the wire pressure ring 2021, the overall mechanical strength of the wire pressure ring 2021 can be improved.

[0030] In one embodiment of the present invention, in order to facilitate the limiting of the conductive insert 4, a positioning through hole 7 is provided on the conductive insert 4 to cooperate with the snap-fit ​​protrusion 501. In this embodiment, by providing the positioning through hole 7 on the conductive insert 4, when the conductive insert 4 is inserted into the insertion through slot 2032, the snap-fit ​​protrusion 501 can be snapped into the positioning through hole 7 to achieve the snap-fit ​​limiting effect between the conductive insert 4 and the insertion through slot 2032, so as to avoid detachment and affect the conductive connection.

[0031] like Figure 6 As shown, in one embodiment of the present invention, in order to improve the overall mechanical strength, a reinforcing conductive plate 401 is provided on the upper surface of the conductive insert 4. In this embodiment, the mechanical strength of the overall component can be improved by providing a reinforcing conductive plate 401 on the upper surface of the conductive insert 4.

[0032] In one embodiment of the present invention, the width W of the plug-in portion 203 is 7.6mm ± 0.05mm, and the height H1 of the plug-in through slot 2032 is 3mm ± 0.1mm.

[0033] In this embodiment, the surface of the strip 1 is provided with a plurality of rectangular holes at equal intervals, and a through hole is provided between two adjacent rectangular holes. The hole design reduces the loss of metal material and saves costs.

[0034] Working principle: In this embodiment, a multifunctional spring connector bar is disclosed. During use, the connection point between the left side of each spring body 2 and the material strip 1 (i.e., the material strip connection part 204 is separated from the material strip 1) needs to be cut open to separate each spring body 2 from the material strip 1. The independent spring bodies 2 have the following connection methods:

[0035] 1. When only one direction of the external wire needs to be connected, the conductive tab 4 on the right side is not functional. It can be cut along the bending groove 301 using scissors, forming the following configuration: Figure 9 The structure shown can be used as a standard spring, applicable to refrigerator compressor springs or children's electric vehicle charging springs. Later, when an external wire or connector is inserted into the insertion slot 2032, the inclined limiting strip 5 within the slot 2032 will press down when the external wire or connector is inserted, and then try to return to its original position under force. This works in conjunction with the arc-shaped limiting part above the insertion slot 2032 (structural reference). Figure 7 Then, the wires or connectors inserted into the plug slot 2032 are limited within the plug slot 2032, preventing them from falling out at will;

[0036] 2. When it is necessary to change the insertion direction, multiple spring bodies 2 can be used. When inserting, simply bend the conductive insert 4 on one of the two adjacent spring bodies 2 according to the installation angle, and then insert it into the insertion slot 2032 of the other spring body 2; thereby changing the installation position of the insertion slot 2032.

[0037] Therefore, this structure can be used to connect to the existing spring-loaded connectors or wires as required, and the connection direction can be changed as required, thus achieving a multi-functional connection method, making it more applicable, easier to connect, and unrestricted in the connection direction.

[0038] Furthermore, by setting a limiting pressure strip 5 with one end tilted upwards, it can not only limit and lock the wires or connectors inserted into the plug slot 2032 to prevent them from coming loose after insertion, but also, since the limiting hook 6 is located outside the plug slot 2032, pressing down the limiting hook 6 will press down the entire limiting pressure strip 5, separating the limiting pressure strip 5 from the external wires or connectors, making it convenient to pull the external wires or connectors out of the plug slot 2032 later, facilitating disassembly.

[0039] It should also be noted that the material strip connecting part 204, wire sheath foot 201, wire core foot 202, plug-in part 203, conductive insert 4, reinforcing conductive plate 401, bending part 3 and limiting pressure strip 5 are all made of metal conductive material. The specific material used is a conventional technology in this field, so it will not be described in detail here.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
