Description

Technical Field

[0001] This invention relates to an electrical connection structure, and more particularly to a snap-fit ​​electrical connection structure and a relay socket. Background Technology

[0002] Relay sockets feature a spring clip and a lead-out tab. The spring clip holds the relay pins, while the lead-out tab serves as the output terminal of the relay socket. Traditionally, the spring clip and lead-out tab are riveted, welded, or integrally molded together. However, riveting or welding adds extra steps and requires careful control over the bonding force and expansion, and can result in missed riveting or welding. Integrating the spring clip and lead-out tab into a single unit leads to low material utilization, high component cost, and deformation during electroplating or electroless plating, potentially causing component failure or assembly difficulties. Therefore, some have proposed connecting the spring clip and lead-out tab with wires. However, finding a convenient and effective way to connect the spring clip and wires remains a problem that needs to be solved. Summary of the Invention

[0003] The purpose of this invention is to address the technical problems existing in the prior art by providing a snap-fit ​​electrical connection structure and a relay socket.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a snap-fit ​​electrical connection structure, including a clamping spring and a wire. The clamping spring is provided with a clamping part and a snap-fit ​​part. The snap-fit ​​part includes a socket and a plurality of snap-fit ​​pieces distributed circumferentially along the socket. One end of the wire passes through the socket, and each snap-fit ​​piece snaps the wire.

[0005] Furthermore, each of the snap-fit ​​pieces is formed by bending, and the tail end of each snap-fit ​​piece is embedded in the wire.

[0006] Furthermore, the clamping spring includes a main spring and an auxiliary spring. One end of the main spring is provided with the clamping part, and the auxiliary spring is integrally connected to the other side of the main spring. The auxiliary spring is bent to form the insertion port with the main spring.

[0007] Furthermore, one of the snap-fit ​​pieces is cut and bent from a corresponding part of the main spring, while the remaining snap-fit ​​pieces are integrally connected to the auxiliary spring.

[0008] Furthermore, each of the snap-fit ​​pieces is integrally connected to the auxiliary spring piece.

[0009] Furthermore, the clamping spring includes a main spring and an auxiliary spring. One end of the main spring is provided with the clamping part, and the other end of the main spring is integrally connected to the auxiliary spring. Each snap-fit ​​piece is cut and bent from the corresponding part of the auxiliary spring, and the hollowed-out part of the auxiliary spring after cutting forms the insertion port.

[0010] Furthermore, the clamping part includes two clamping plates arranged opposite to each other, wherein the root of one clamping plate is integrally connected to one end of the main spring plate, and the side of the root of the other clamping plate is integrally connected to the side of one end of the main spring plate.

[0011] Furthermore, there are two auxiliary springs, which are integrally connected to the opposite sides of the main spring.

[0012] Furthermore, each of the two clamping pieces has a slit, which divides the clamping piece into two parts.

[0013] Furthermore, the plurality of snap-fit ​​tabs are located on the side of the socket corresponding to the insertion direction of the wire; the number of snap-fit ​​tabs is at least three.

[0014] Furthermore, the number of the snap-fit ​​pieces is at least four, and the clamping point of each snap-fit ​​piece with the wire is at the same height as or has a height difference from the clamping point of the adjacent snap-fit ​​piece with the wire.

[0015] The present invention also provides a relay socket, including a socket body and a lead-out piece disposed on the socket body; it also includes a snap-fit ​​electrical connection structure as described above, wherein the clamping spring is disposed on the socket body and the other end of the wire is electrically connected to the lead-out piece.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Because the clamping spring also has a snap-fit ​​part, which includes a socket and several snap-fit ​​pieces distributed circumferentially along the socket, with one end of the wire passing through the socket and each snap-fit ​​piece snapping the wire in place, this invention enables a quick and effective connection between the clamping spring and the wire. This allows the clamping spring to be connected to the lead-out piece via the wire, thereby reducing riveting or welding processes, avoiding missed riveting or welding, saving material costs, and preventing part deformation caused by electroplating. Furthermore, this invention can standardize clamping springs for different products by simply replacing the wire, thus reducing the number of parts and saving on parts management costs.

[0018] 2. The tail ends of each snap-fit ​​piece are respectively embedded in the wire. On the one hand, this eliminates the need for additional auxiliary structures for the snap-fit ​​piece and / or the wire, making the overall structure very simple. On the other hand, it can effectively prevent the wire from detaching in the opposite direction of the wire insertion. Furthermore, the larger the contact area between the snap-fit ​​piece and the wire, the greater the force that restricts the wire from separating in the opposite direction, and the more reliable the snap-fit.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the snap-fit ​​electrical connection structure and relay socket of the present invention are not limited to the embodiments. Attached Figure Description

[0026] Example 1

[0027] Please see Figure 1 , Figure 2 As shown, a snap-fit ​​electrical connection structure of the present invention includes a clamping spring 1 and a wire 2. The clamping spring 1 is provided with a clamping part and a snap-fit ​​part. The snap-fit ​​part includes a socket 14 and a plurality of snap-fit ​​pieces 13 distributed circumferentially along the socket 14. One end of the wire 2 passes through the socket 14, and each snap-fit ​​piece 13 snaps into the wire 2. Specifically, each snap-fit ​​piece 13 is formed by bending, and the tail end of each snap-fit ​​piece 13 is embedded in the wire 2.

[0028] In this embodiment, the clamping spring 1 includes a main spring 11 and an auxiliary spring 12. One end of the main spring 11 has the clamping portion, and the auxiliary spring 12 is integrally connected to the other side of the main spring 11, forming the insertion port 14 with the main spring 11 through bending. Specifically, there are two auxiliary springs 12, which are integrally connected to opposite sides of the main spring 11, forming a roughly triangular insertion port 14 with the main spring 11. In other embodiments, there is one auxiliary spring.

[0029] In this embodiment, one snap-fit ​​piece 13a is cut and bent from a corresponding portion of the main spring piece 11, and the remaining snap-fit ​​pieces 13b are integrally connected to the end of the auxiliary spring piece 12 near the clamping part. The plurality of snap-fit ​​pieces 13 are located on the side of the socket 14 corresponding to the insertion direction of the wire 2, and specifically, there are three snap-fit ​​pieces 13. Therefore, the remaining two snap-fit ​​pieces 13b are integrally connected to the two auxiliary spring pieces 12 respectively. In other embodiments, each snap-fit ​​piece is integrally connected to the end of the auxiliary spring piece near the clamping part.

[0030] In this embodiment, the clamping part includes two clamping pieces 15 arranged opposite to each other. The root of one clamping piece is integrally connected to one end of the main spring 11, and the side of the root of the other clamping piece is integrally connected to one end of the main spring 11. The terms "integral connection" and "integral connection" both refer to integral molding.

[0031] In this embodiment, the two clamping pieces 15 are respectively provided with a cut 151, which divides the clamping piece 15 into two parts.

[0032] In this invention, a snap-fit ​​electrical connection structure is assembled by first inserting one end of the wire 2 into the socket 14 from the side away from the clamping part. Then, corresponding portions of the main spring 11 and auxiliary spring 12 are bent inwards towards the socket 14 to form snap-fit ​​pieces 13, with the tail ends of each snap-fit ​​piece 13 embedded in the side of the wire 2. This is because the wire 2 is generally made of copper, which is relatively soft. Therefore, the portion of the wire 2 that contacts the snap-fit ​​piece 13 will have an indentation pressed into the tail end of the snap-fit ​​piece 13, thus allowing the tail end of the snap-fit ​​piece to interlock with the side of the wire 2, making it difficult for the wire 2 to detach from the clamping spring 1.

[0033] The present invention provides a relay socket, comprising a socket body, a lead-out piece disposed on the socket body, and a snap-fit ​​electrical connection structure of the present invention as described in Embodiment 1 above. The clamping spring is disposed on the socket body, and the other end of the wire is electrically connected to the lead-out piece. Specifically, the other end of the wire and the lead-out piece can be connected by welding, riveting, or screw fixing.

[0034] Because this invention enables a quick and efficient connection between the spring clip and the wire, allowing the spring clip to be connected to the lead-out piece via the wire, it reduces the riveting process between the spring clip 1 and the lead-out piece, avoids missed riveting, saves material costs, and prevents part deformation caused by electroplating. Furthermore, this invention can standardize spring clips for different products by simply replacing the wire, thus reducing the number of parts and saving on parts management costs.

[0035] Example 2

[0036] Please see Figure 3 , Figure 4As shown, the snap-fit ​​electrical connection structure of the present invention differs from the first embodiment described above in that: the socket 14 is approximately square, and there are four snap-fit ​​pieces, which are positioned on the four sides of the socket 14. The snap-fit ​​point of each snap-fit ​​piece and the wire 2 has a height difference from the snap-fit ​​point of the adjacent snap-fit ​​piece and the wire 2, thus avoiding interference between adjacent snap-fit ​​pieces.

[0037] In this embodiment, as in Embodiment 1, one snap-fit ​​piece 13a is cut and bent from a corresponding part of the main spring piece 11. Among the remaining three snap-fit ​​pieces, two opposite snap-fit ​​pieces 13b are integrally connected to the two auxiliary spring pieces 12 respectively. The remaining snap-fit ​​piece 13c is divided into two parts, one part is integrally connected to one of the auxiliary spring pieces 12, and the other part is integrally connected to the other auxiliary spring piece 12.

[0038] Example 3

[0039] Please see Figure 5 , Figure 6 As shown, the snap-fit ​​electrical connection structure of the present invention differs from the above embodiments in that: the other end of the main spring 11 is integrally connected to the auxiliary spring 12, and the two are approximately at a 90° angle. Each snap-fit ​​piece 13 is cut and bent from a corresponding part of the auxiliary spring 12, and the hollowed-out part of the auxiliary spring 12 forms the socket 14. That is, each snap-fit ​​piece 13 extends from the edge of the socket 14 towards the center, and each snap-fit ​​piece 13 is bent along the direction in which the wire 2 is inserted. The socket 14 is circular.

[0040] In this embodiment, each snap-fit ​​piece 13 is approximately fan-shaped with a narrow tail and a wide root, and the snap-fit ​​point of each snap-fit ​​piece 13 and the wire 2 is at the same height as the snap-fit ​​point of the adjacent snap-fit ​​piece and the wire 2. The number of snap-fit ​​pieces 13 is four, but not limited to this.

[0041] The above embodiments are only used to further illustrate a snap-fit ​​electrical connection structure and relay socket of the present invention. However, the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the technical solution of the present invention.
