[0001] This utility model belongs to the field of connector technology, specifically relating to a spring-type electrical connector that prevents buttons from popping out and disengaging. Background Technology
[0002] Spring-loaded electrical connectors that prevent button detachment are a common type of electrical connector, offering advantages such as simple connection and ease of use. These connectors contain a button for pushing the spring back to its original position. During use, when the spring presses against the wire, it may collide with the button, pushing it outwards. Over time, the button may spring off the connector body, leading to connector failure.
[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0004] The purpose of this invention is to provide a spring-loaded electrical connector to solve the problem of button stability.
[0005] To achieve the above objectives, a specific embodiment of this utility model provides a spring-loaded connector for preventing button detachment, comprising a housing, a conductive sheet, a spring, and a button. The housing has an internal mounting space, and the housing has a first channel and a second channel communicating with the mounting space. The first channel is used to insert a wire. A first stop protrudes from one side wall of the second channel. The first stop includes a main body and a protrusion extending from the main body towards the mounting space; the protrusion has a different size from the main body. One end of the conductive sheet extends into the mounting space. The spring is made of an elastic material and is used to press the inserted wire against the conductive sheet. The button is disposed within the second channel and can move up and down along the second channel, used to press the spring to disengage the wire from the conductive sheet. One side wall of the button has a first groove for accommodating the first stop and a second groove extending from the end of the first groove, the second groove accommodating the protrusion.
[0006] In one or more embodiments of the present invention, the spring includes a connecting portion extending toward the first channel, a fixing portion for fixing the connecting portion, and a pressing portion extending from the fixing portion for being pressed by a wire.
[0007] In one or more embodiments of this utility model, the fixing part includes two hooks, and the connecting part is provided with an inwardly recessed section on both sides. When the wire squeezes the squeezing part, the inwardly recessed section is hooked by the hooks, so that the connecting part is fixed to the fixing part.
[0008] In one or more embodiments of this utility model, the length of the end of the protrusion away from the main body is greater than the length of the end connected to the main body.
[0009] In one or more embodiments of the present invention, the opening distance of the second groove is greater than the bottom length, and the opening distance of the second groove is greater than the maximum length of the protrusion, and the bottom length of the second groove is greater than the minimum length of the protrusion.
[0010] In one or more embodiments of this utility model, a second stop protrudes from the other side wall of the second channel, and a third stop protrudes from the button. The second stop and the third stop cooperate to limit the distance the button can move in the direction of the mounting space.
[0011] In one or more embodiments of this utility model, the first stop and the second stop are disposed on two opposite side walls of the second channel.
[0012] In one or more embodiments of the present invention, the second stop and the third stop are configured such that when the second stop and the third stop abut, the end of the button away from the spring enters the second channel.
[0013] In one or more embodiments of this utility model, the end of the first stop block facing away from the installation space is provided with an inclined guide surface, and the end of the button facing the installation space is provided with an arc-shaped surface that cooperates with the guide surface.
[0014] In one or more embodiments of this utility model, a gap exists between the button and the second channel.
[0015] Compared with the prior art, the spring-type electrical connector of this utility model for preventing button detachment adopts a two-stage anti-detachment structure, which greatly improves the stability between the button and the housing and effectively prevents the button from being ejected.

Detailed Implementation
[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort should fall within the protection scope of this utility model.
[0028] like Figure 1-4As shown, a spring-loaded electrical connector 100 for preventing button detachment in one embodiment of this utility model includes a housing 10, a conductive sheet 20, a spring 30, and a button 40. The housing 10 has an internal mounting space, and a first channel 11 and a second channel 12 communicating with the mounting space are provided on the housing. The first channel 11 is used to insert a wire, and the button 40 is disposed in the second channel 12 and can move up and down within the second channel 12 to reset the spring 30. One end of the conductive sheet 20 extends into the mounting space within the housing 10. Figure 2 The conductive sheet 20 is entirely abutted against the inner wall of the housing 10, with one end extending to the opening of the first channel 11. The spring sheet 30 is made of elastic material and is used to press the inserted wire against the conductive sheet 20.
[0029] When the wire is inserted into the first channel 11, it triggers the spring 30. When the spring 30 is triggered, it presses the wire against the conductive sheet 20, which in turn pushes the button 40 upward. Typically, a limiting structure is provided between the second channel 12 and the button 40 to prevent the button 40 from being bounced off. However, under prolonged use, the spring 30 will repeatedly impact the button 40, and the limiting structure may fail after repeated impacts, causing the button 40 to still be bounced off.
[0030] To avoid the above situation, the spring-loaded electrical connector 100 for preventing button detachment in this embodiment adopts an improved limiting structure, including a first stop 13 protruding from one side wall of the second channel 12, and a first groove 41 recessed in one side wall of the button 40 to accommodate the first stop 13. Both the first stop 13 and the first groove 41 adopt a two-section design. The first stop 13 includes a main body 131 and a protrusion 132 extending from the main body 131 toward the mounting space. The main body 131 and the protrusion 132 have different dimensions. A second groove 411 extends from the end of the first groove 41. The second groove 411 is used to accommodate the protrusion 132. It is roughly similar in shape to the protrusion 132 and its depth is less than the protrusion height of the protrusion 132, so that there is a gap between the end of the main body 131 and the first groove 41.
[0031] The above configuration ensures that when button 40 is pushed upward by spring 30, the protrusion 132 first contacts the bottom of the second groove 411. Only when the protrusion 132 and / or the second groove 411 are damaged, causing the blocking effect to fail, does the blocking effect continue to be provided by the main body 131 and the ends of the first groove 41. Therefore, the protrusion 132 and the second groove 411 provide a buffer for button 40 and the first stop 13, greatly improving the stability between button 40 and housing 10 and effectively preventing button 40 from being bounced off housing 10.
[0032] The spring 30 includes a connecting portion 31 extending toward the first channel 11, a fixing portion 32 for fixing the connecting portion 31, and a pressing portion 34 extending from the fixing portion 32 for being pressed by a wire. In the initial state, the connecting portion 31 is fixed to the fixing portion 32. After the wire is inserted, it contacts and presses the pressing portion 34. The pressing portion 34 causes the fixing portion 32 to deform, thereby releasing the connecting portion 31. The connecting portion 31 returns to its original shape and presses the wire against the conductive sheet 20.
[0033] exist Figure 4 In the illustrated embodiment, the fixing part 32 includes two hooks, while the connecting part 31 is provided with an inwardly recessed section 33 on both sides. In the initial state, the inwardly recessed section 33 is engaged with the two hooks, subjected to a certain amount of compression, and stores energy (e.g., Figure 3 As shown in the figure, when the wire (not shown) is inserted through the first channel 11, the wire contacts and pushes the squeezing part 34. The squeezing part 34 is pressed, causing the fixing part 32 to move downward. The hook deforms and disengages from the concave section 33, thereby releasing the connecting part 31. The connecting part 31 releases its stored energy and recovers its deformation, squeezing the wire against the conductive sheet 20, so that the wire and the conductive sheet 20 are attached together, achieving the final connection (as shown in the figure). Figure 2 (As shown). When it is necessary to pull out the wire, it cannot be pulled out smoothly due to the compression of the spring piece 30. At this time, press down on the button 40, which can contact and squeeze the connecting part 31 to cause it to elastically deform, pushing the connecting part 31 towards the fixing part 32 until the concave section 33 is re-locked on the hook (as shown). Figure 3 As shown in the figure, the wire is detached from the spring piece 30 and can be pulled out smoothly.
[0034] It should be noted that other spring-loaded structures that can achieve the above-mentioned function of preventing buttons from disengaging are also within the protection scope of this utility model.
[0035] Preferably, the protrusion 132 adopts a trapezoidal structure, and the length of the end away from the main body 131 is less than the length of the end connected to the main body 131.
[0036] Correspondingly, the second groove 411 adopts a trapezoidal structure similar in shape to the protrusion 132, that is, the distance of its opening is greater than the length of its bottom. In order for the protrusion 132 to be correctly inserted into the second groove 411, the distance of the opening of the second groove 411 is greater than the maximum length of the protrusion 132 (the length on the side connected to the main body 131), while the length of the bottom of the second groove 411 is greater than the minimum length of the protrusion 132 (the length on the side away from the main body 131).
[0037] Preferably, to prevent the button 40 from moving downwards excessively and excessively compressing the spring 30, which could cause plastic deformation of the spring 30 and thus lead to the failure of the spring-type electrical connector 100 that prevents the button from disengaging, a mechanism for limiting the inward movement distance of the button 40 is provided between the button 40 and the second channel 12, in addition to the limiting structure that prevents the button 40 from disengaging. For example... Figure 6 As shown, a second stop 14 protrudes from the other side wall inside the second channel 12, and a third stop 42 that cooperates with the second stop 14 is provided on the button 40. When the second stop 14 and the third stop 42 come into contact, the button 40 cannot continue to move inward.
[0038] In such Figure 7 In the embodiment shown, the first stop 13 and the second stop 14 are disposed on two opposite side walls of the second channel 12, and the corresponding first groove 41 and the third stop 42 are disposed on two opposite side walls of the button 40.
[0039] In one embodiment, the second stop 14 and the third stop 42 are configured such that when the two stop blocks abut against each other, the button 40 just presses and fixes the connecting part 31 to the fixing part 32. At this time, the button 40 cannot continue to move in the direction of the installation space, thus avoiding the situation where the spring piece 30 is over-pressed and fails.
[0040] In another embodiment, the second stop 14 and the third stop 42 are configured such that when they abut against each other, the end of the button 40 away from the spring 30 enters the second channel 12, that is, the entire button 40 is submerged in the second channel 12, thereby improving the overall integrity and aesthetics of the spring-type electrical connector 100 that prevents the button from disengaging.
[0041] In one embodiment, the outer shell 10 is integrally formed. Therefore, in order to facilitate the insertion of the button 40 into the second channel 12, there is a gap between the button 40 and the second channel 12. An inclined guide surface 133 is provided on the first stop 13. The guide surface is provided at the end of the first stop 13 away from the installation space, while an arc-shaped surface 43 is provided at the end of the button 40 facing the installation space. When inserted into the second channel 12, the arc-shaped surface 43 and the guide surface 133 cooperate with each other to correctly insert the button 40 into the second channel 12.
[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
