Description

Technical Field

[0001] The present invention relates to a conductive structural member, in particular to a structural member and a relay socket with reliable connection. Background Art

[0002] An input structural member and an output structural member are provided in a relay socket. The clamping portion of the input structural member is used to clamp the lead-out foot of the relay. The output structural member serves as the output part of the relay socket and is used for electrically connecting with an external wire; a wire is electrically connected between the input structural member and the output structural member. Currently, the input structural member and / or the output structural member of the relay socket are generally connected to the wire by a snap connection. When connecting, the wire is pushed in from the wider end of the snap interface provided on the input structural member / output structural member and extends out from the narrower end of the snap interface, and is simultaneously clamped by the narrower end of the snap interface. Such a snap interface only realizes one-way limiting, making the wire non-loosening-proof in the pushing direction, so its connection with the wire is not reliable enough. Summary of the Invention

[0003] In view of the technical problems existing in the prior art, the present invention provides a structural member and a relay socket with reliable connection.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a structural member with reliable connection, including a conductive body, and the body is provided with a snap connection unit for electrically connecting with a wire; the snap connection unit forms a first snap interface and a second snap interface for clamping the same wire and allowing the wire to be laterally pressed in. The diameter of the first snap interface gradually increases from the first snap interface to the second snap interface, and the diameter of the second snap interface gradually increases from the second snap interface to the first snap interface, or the diameter of the first snap interface gradually decreases from the first snap interface to the second snap interface, and the diameter of the second snap interface gradually decreases from the second snap interface to the first snap interface.

[0005] Further, the snap connection unit includes at least two first cantilevers circumferentially spaced apart along the wire to be clamped and at least two second cantilevers circumferentially spaced apart along the wire to be clamped. The first snap interface is formed between at least two first cantilevers, and the second snap interface is formed between at least two second cantilevers.

[0006] Further, the first cantilevers and the second cantilevers are in one-to-one correspondence, and a connecting portion is respectively connected between each first cantilever and the corresponding second cantilever, and the connecting portion is connected to the body.

[0007] Further, the number of both the first cantilevers and the second cantilevers is two, and the two first cantilevers are oppositely arranged, and the two second cantilevers are oppositely arranged.

[0008] Further, the first snap interface and the second snap interface are in an up-and-down relationship.

[0009] Further, the body includes a substrate, and the clamping unit is disposed on the substrate.

[0010] Further, the body further includes a pair of reed clamping plates disposed on the substrate.

[0011] Further, the body further includes an L-shaped terminal board, and the horizontal portion of the terminal board is connected to the substrate.

[0012] The present invention further provides a relay socket, including a base, an input structural member, an output structural member, and a wire. The input structural member and the output structural member are respectively installed in the base, and both ends of the wire are electrically connected to the input structural member and the output structural member respectively; the input structural member and / or the output structural member has a clamping unit of the structural member with reliable connection as described in the present invention above, and clamps the wire through its first clamping interface and second clamping interface.

[0013] Further, it further includes a spring piece, which is disposed in the base and cooperates with the output structural member to press the inserted external wire against the output structural member.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Since the clamping unit forms a first clamping interface and a second clamping interface for clamping the same wire and allowing the wire to be laterally pressed in, the diameter of the first clamping interface gradually increases from the first clamping interface to the direction of the second clamping interface, the diameter of the second clamping interface gradually increases from the second clamping interface to the direction of the first clamping interface, or, the diameter of the first clamping interface gradually decreases from the first clamping interface to the direction of the second clamping interface, the diameter of the second clamping interface gradually decreases from the second clamping interface to the direction of the first clamping interface, so that the first clamping interface and the second clamping interface of the present invention can achieve two-way limiting of the wire, form an interlock, and limit the wire from being pulled or pushed, thereby enabling the structural member to firmly clamp the wire. In addition, the clamping unit of the present invention uses two clamping interfaces (i.e., the first clamping interface and the second clamping interface) to clamp the wire. Compared with the prior art using a single clamping interface, the clamping points of the present invention are doubled, making the electrical connection between the structural member and the wire more reliable.

[0016] 2. The clamping unit preferably includes at least two first cantilevers and at least two second cantilevers. The at least two discrete first cantilevers form the first clamping interface, and the at least two discrete second cantilevers form the second clamping interface, which is not only beneficial to saving material costs, but also beneficial to improving the clamping effect, and making the structure of the clamping unit simpler and easier to produce.

[0026] First embodiment

[0027] Please refer to Figures 1-3 As shown, a structural member with reliable connection of the present invention includes a conductive body 1, and the body 1 is provided with a clamping unit 2 for electrically connecting with a wire. The clamping unit 2 forms a first clamping interface 21 and a second clamping interface 22 for clamping the same wire and allowing the wire to be laterally pressed in. The diameter of the first clamping interface 21 gradually increases from the direction of the first clamping interface 21 to the second clamping interface 22, and the diameter of the second clamping interface 22 gradually increases from the direction of the second clamping interface 22 to the first clamping interface 21, but it is not limited thereto. In other embodiments, the diameter of the first clamping interface gradually decreases from the direction of the first clamping interface to the second clamping interface, and the diameter of the second clamping interface gradually decreases from the direction of the second clamping interface to the first clamping interface. The first clamping interface 21 and the second clamping interface 22 are specifically in an up-and-down relationship, but it is not limited thereto. In other embodiments, the first clamping interface and the second clamping interface are in a left-and-right relationship or a front-and-back relationship, etc. The "lateral direction" refers to the direction perpendicular to the center line of the first clamping interface 21 / second clamping interface 22.

[0028] In this embodiment, the clamping unit 2 includes at least two first cantilevers 23 circumferentially and spaced apart along the wire to be clamped and at least two second cantilevers 24 circumferentially and spaced apart along the wire to be clamped. A first clamping opening 21 is formed between at least two first cantilevers 23, and a second clamping opening 22 is formed between at least two second cantilevers 24. Specifically, the number of the first cantilevers 23 and the second cantilevers 24 is two each. Since the first clamping opening 21 and the second clamping opening 22 are in an up-and-down relationship, the two first cantilevers 23 and the two second cantilevers 24 are also in an up-and-down relationship, and the two first cantilevers 23 are opposite to each other left and right, and the two second cantilevers 24 are opposite to each other left and right. At the same time, the first clamping opening 21 formed between the two first cantilevers 23 is similar to an inverted V shape, and the second clamping opening 22 formed between the two second cantilevers 24 is similar to a V shape. The diameter of the first clamping opening 21 is the distance between the two first cantilevers 23, and the diameter of the second clamping opening 22 is the distance between the two second cantilevers 24.

[0029] In this embodiment, the first cantilevers 23 and the second cantilevers 24 correspond to each other one by one, and a connecting portion 25 is respectively connected (the connection includes an integrally connected form or other non-integrally connected forms) between each first cantilever 23 and the corresponding second cantilever 24, and the rear end of the connecting portion 25 is connected (the connection includes an integrally connected form or other non-integrally connected forms) to the body 1. The arrangement of the connecting portion 25 makes it easier for each first cantilever 23 and the corresponding second cantilever 24 to be connected to the body 1.

[0030] In this embodiment, the body 1 includes a vertical substrate 11, and the clamping unit 2 is arranged on the substrate 11: the connecting portions 25 between each first cantilever 23 and the corresponding second cantilever 24 are respectively connected to the left and right side surfaces of the substrate 11, so that each first cantilever 23 and the second cantilever 24 are located on the front side of the front plate. Specifically, the connecting portion 25 extends from the substrate 11 and forms a 90° angle with the substrate 11, and each first cantilever 23 and the second cantilever 24 extend from the corresponding connecting portion 25 and form an approximately 45° angle with the connecting portion 25.

[0031] In this embodiment, the body 1 further includes a pair of reed clamping plates 12, which are arranged on the top of the substrate 11. A limiting boss 111 is respectively arranged on the left and right side surfaces of the substrate 11, and the two limiting bosses 111 are opposite to each other left and right and are located between the reed clamping plates 12 and the clamping unit 2.

[0032] A structural member with reliable connection of the present invention can form an input structural member (also called an input clip spring) of a relay socket. When connecting the connecting wire 3 (the wire is a single-strand hard round copper wire), one end of the wire 3 is simultaneously pressed laterally (specifically, in the rearward direction) into its first clamping opening 21 and the second clamping opening 22, as Figure 3As shown, at this time, the tops of the two first cantilevers 23 are inserted into the wire 3 under the action of the inherent elastic force of the structural member, and the width of the contact section between it and the wire 3 is D. At the same time, the bottoms of the two second cantilevers 24 are also inserted into the wire 3 under the action of the inherent elastic force of the structural member, and the width of the contact section between it and the wire 3 is also D. Therefore, the present invention can realize two-way limit of the wire in the up and down directions, form an interlock, and limit the wire from being pulled or pushed, so that the structural member firmly clamps the wire. In addition, the structural member of the present invention uses two card interfaces (i.e., the first card interface 21 and the second card interface 22) to clamp the wire. Compared with the prior art using a single card interface, the card contact points of the present invention are doubled, making the electrical connection between the structural member and the wire more reliable.

[0033] Embodiment 2

[0034] Please refer to Figure 4 As shown, a structural member with reliable connection of the present invention is different from the first embodiment above in that: the body 1 further includes an L-shaped terminal board 13, and the horizontal part of the terminal board 13 is connected to the top end of the substrate 11. Specifically, the horizontal part of the terminal board 13 is provided with an L-shaped notch 133, and the substrate 11 and the card connection unit 2 thereon are located in the L-shaped notch 133.

[0035] A structural member with reliable connection of the present invention can form an output structural member of a relay socket. The top end of the vertical part of the terminal board 13 is provided with a limit block 131 bent outward for installation limit of the whole structural member. The inner side of the vertical part of the terminal board 13 is provided with an inclined block 132 inclined downward to improve the anti-pulling ability of the inserted external wire. The inner side of the vertical part of the terminal board 13 can further be provided with a rib for separating the two inserted external wires.

[0036] A structural member with reliable connection of the present invention, its first card interface 21 and second card interface 22 can also realize up and down limit of the wire in the up and down directions, form an interlock, so as to limit the wire from being pulled or pushed.

[0037] Embodiment 3

[0038] Please refer to Figures 5-8As shown in the figure, a relay socket of the present invention includes a base 4, an input structural member 5, an output structural member 6, and a wire 3. The input structural member 5 and the output structural member 6 are respectively installed in the base 4. The wire 3 is a single-strand rigid round copper wire, and its two ends are respectively electrically connected to the input structural member 5 and the output structural member 6. The input structural member 5 and / or the output structural member 6 has a clamping unit 2 of the structural member with reliable connection as described in the above-mentioned Embodiment 1 and Embodiment 2, and clamps the wire 3 through its first clamping interface 21 and second clamping interface 22. Specifically, the input structural member 5 adopts the structural member with reliable connection as described in the above-mentioned Embodiment 1, and this input structural member 5 can also be called an input clip spring, etc.; the output structural member 6 adopts the structural member with reliable connection as described in the above-mentioned Embodiment 2, and this output structural member 6 can also be called a lead-out end or an output terminal board, etc.

[0039] In this embodiment, the present invention further includes a spring piece 7. The spring piece 7 is arranged in the base 4 and cooperates with the output structural member 6 to press the inserted external wire against the vertical part of the output structural member 6. In this way, the relay socket of the present invention constitutes a direct plug-in relay socket.

[0040] In this embodiment, the number of the bases 4 is at least two. These at least two bases 4 have the same structure and are spliced together. Specifically, the adjacent bases 4 are spliced by the way of inserting and matching a splicing shaft and a splicing hole. The number of the bases 4 is specifically two, but it is not limited thereto. In other embodiments, the number of the bases is one or more than two. The two bases 4 have basically the same structure and are basically symmetrical. As Figure 7 shown, on the relative inner sides of the two bases 4, one is provided with a splicing shaft 41 and the other is provided with a splicing hole 42. The splicing shaft 41 and the splicing hole 42 are inserted and matched. The number of the output structural member 6, the spring piece 7, the input structural member 5, and the wire 3 on each base 4 is multiple and corresponds one by one. Therefore, the present invention is applicable to a two-way relay (only one base 4 is used), and is also applicable to a four-way relay (two bases 4 are used). Moreover, when the number of the bases 4 is further increased, the present invention is also applicable to relays with more ways.

[0041] In this embodiment, as Figure 8 shown, the present invention further includes a housing 8. The housing covers the two bases 4 spliced together.

[0042] For a relay socket of the present invention, its input structural member 5 and output structural member 6 respectively use the first clamping interface 21 and the second clamping interface 22 to clamp the wire, which can form an interlock, restrict the wire 3 from being pulled or pushed, and make the electrical connection between the input structural member 5, the output structural member 6 and the wire 3 more reliable.

[0043] The above embodiments are only used to further illustrate a structural member and a relay socket with reliable connection according to the present invention. However, the present invention is not limited to the embodiments. Any simple modification, equivalent change and modification 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.
