Description

Technical Field

[0001] This utility model relates to the field of contacts for electrical connectors, and more particularly to a plate socket and connector. Background Technology

[0002] With the development of new energy vehicle technology, surface mount high-current connectors are favored by OEMs due to their lower cost and higher current carrying capacity compared to round pin / round hole high-current connectors. Surface mount high-current connectors include plug connectors and socket connectors, one of which contains a surface mount pin, and the other contains a surface mount socket. Chinese invention patent application CN111564720A discloses a double-spring surface mount socket structure and connector, including a copper busbar and insert plate assemblies disposed on both sides of the copper busbar. The insert plate assembly includes an inner spring, an outer spring, and a spring clip. One end of the insert plate assembly is connected to the copper busbar, and the other end extends beyond the end of the copper busbar and is spaced apart, forming a mating space for the surface mount pin to be inserted. This double-spring surface mount socket structure has reliable current carrying capacity and good stability. However, the stacking of the two sets of insert plate assemblies and the copper busbar results in a larger thickness at the connection position of the two sets of insert plate assemblies and the copper busbar, occupying a large space when installed in the connector housing, resulting in a larger overall connector size. Utility Model Content

[0003] The purpose of this invention is to provide a surface-mount socket to solve the problem of large size in existing surface-mount sockets while ensuring current flow and stability. Simultaneously, the purpose of this invention is also to provide a connector to solve the problem of large size in existing connectors while ensuring current flow and stability.

[0004] The present invention relates to a plate-type socket comprising a plug-in plate assembly arranged opposite to each other. The plug-in plate assembly includes an inner spring and a pressure spring stacked on the outside of the inner spring. The inner spring includes a tail connecting section and a front contact section. The pressure spring includes a tail fixing section and a front pressure section. The tail fixing section is fixedly connected to the tail connecting section. The front pressure section elastically presses against the front contact section from the outside to the inside. The front contact sections of the two inner springs are spaced apart and form a mating space for inserting the plate-type pin. The tail connecting sections of the two inner springs are fitted and fixed. The edge of the tail connecting section of the inner spring extends straight with an extension portion for connecting external cables or conductors.

[0005] Furthermore, the outer extensions of the two inner springs extend straight backward and fit together. The width of the outer extension is greater than the width of the plug-in assembly on its front side. A forward-facing stop step is formed at the junction of the outer extension and the tail connection section. The pressure spring is provided with a locking claw extending backward and upward. The stop step is used to stop and cooperate with the positioning surface on the connector housing, and the locking claw is used to cooperate with the locking groove on the connector housing.

[0006] Furthermore, the locking claw is positioned at the middle of the width of the pressure spring.

[0007] Furthermore, the rear end of the locking pawl extends above the tail fixing section.

[0008] Furthermore, when the outer portions of the two inner spring sheets are fitted together, they are positioned and inserted through several pairs of positioning holes and positioning posts.

[0009] Furthermore, the positioning holes and positioning pins are located at the edge of the extension portion.

[0010] Furthermore, the tail fixing section is attached to the outside of the tail connecting section, and the inner springs and pressure springs of the two insert plate assemblies are fixedly connected by a connector that passes through both the tail fixing section and the tail connecting section, thereby keeping the tail connecting section of the two inner springs and the external connecting end in contact.

[0011] Furthermore, both the inner spring and the pressure spring include forward-extending parallel spring arms in the width direction, with an equal number of spring arms on both, and the spring arms of the pressure spring press inward against the spring arms of the corresponding inner spring.

[0012] Furthermore, the two plug-in components are arranged symmetrically.

[0013] This invention provides a novel plate-type socket. The plate-type socket's connector assembly includes an inner spring and a pressure spring stacked on the outside of the inner spring. This increases current-carrying capacity and ensures stable contact with the compatible plate-type pins. Simultaneously, the tail connecting sections of the two inner springs are fitted and fixed together. The edges of the tail connecting sections of the inner springs extend straight outwards with an extended portion for connecting external cables or conductors. This eliminates the need for a connecting copper busbar between the two connector assemblies to connect external cables; instead, cables or conductors are directly connected through the extended portion on the tail connecting section. Thus, the thickness of the plate-type socket can be minimized while maintaining current-carrying capacity and stability, thereby reducing the overall size of the plate-type socket.

[0014] The connector of this utility model includes a connector housing and a plate socket installed in the connector housing. The plate socket includes a mating piece assembly arranged opposite to each other. The mating piece assembly includes an inner spring and a pressure spring stacked on the outside of the inner spring. The inner spring includes a tail connecting section and a front contact section. The pressure spring includes a tail fixing section and a front pressure section. The tail fixing section is fixedly connected to the tail connecting section. The front pressure section elastically presses against the front contact section from the outside to the inside. The front contact sections of the two inner springs are spaced apart and form a mating space for the insertion of the mating pin. The tail connecting sections of the two inner springs are fitted and fixed. The edge of the tail connecting section of the inner spring extends straight with an extension portion for connecting an external cable or conductor.

[0015] Furthermore, the outer extensions of the two inner springs extend straight backward and fit together. The width of the outer extension is greater than the width of the plug-in assembly on its front side. A forward-facing stop step is formed at the junction of the outer extension and the tail connection section. The pressure spring is provided with a locking claw extending backward and upward. The stop step is used to stop and cooperate with the positioning surface on the connector housing, and the locking claw is used to cooperate with the locking groove on the connector housing.

[0016] Furthermore, the locking claw is positioned at the middle of the width of the pressure spring.

[0017] Furthermore, the rear end of the locking pawl extends above the tail fixing section.

[0018] Furthermore, when the outer portions of the two inner spring sheets are fitted together, they are positioned and inserted through several pairs of positioning holes and positioning posts.

[0019] Furthermore, the positioning holes and positioning pins are located at the edge of the extension portion.

[0020] Furthermore, the tail fixing section is attached to the outside of the tail connecting section, and the inner springs and pressure springs of the two insert plate assemblies are fixedly connected by a connector that passes through both the tail fixing section and the tail connecting section, thereby keeping the tail connecting section of the two inner springs and the external connecting end in contact.

[0021] Furthermore, both the inner spring and the pressure spring include forward-extending parallel spring arms in the width direction, with an equal number of spring arms on both, and the spring arms of the pressure spring press inward against the spring arms of the corresponding inner spring.

[0022] Furthermore, the two plug-in components are arranged symmetrically.

[0023] This invention improves upon existing connectors, particularly by redesigning the plate-type socket. The plate-type socket's contact assembly includes an inner spring and a pressure spring stacked on the outer side of the inner spring. This increases current-carrying capacity and ensures stable contact with the mating plate-type pins. Simultaneously, the tail connecting sections of the two inner springs are fitted and fixed together. The edges of the tail connecting sections of the inner springs extend straight outwards with an extended portion for connecting external cables or conductors. This eliminates the need for a connecting copper busbar between the two contact assemblies to connect external cables; instead, cables or conductors are directly connected through the extended portion on the tail connecting section. Thus, the thickness of the plate-type socket can be minimized while maintaining current-carrying capacity and stability, thereby reducing the overall size of the plate-type socket.

[0028] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0029] The connector of this utility model adopts a new type of plate socket. By changing the structure of the plate socket for connecting external cables, the intermediate copper busbar used for wiring in the prior art is eliminated, the overall thickness of the plate socket is reduced, the space occupied by the plate socket is reduced, and thus the size of the connector is reduced.

[0030] Specifically, the following provides embodiments of the connector of this utility model:

[0031] As a more basic embodiment: such as Figure 1-3 As shown, the connector includes a connector housing with a mounting cavity containing a plate-type socket. The plate-type socket includes two symmetrically arranged contact assemblies. Each contact assembly includes an inner spring 1 and a pressure spring 2 stacked on the outer side of the inner spring 1. In this context, "outer side" refers to the side of the symmetrically arranged contact assemblies that is furthest from each other. The inner spring 1 includes a tail connecting section 10 and a front contact section 11. The tail connecting section 10 connects to the pressure spring 2, and the front contact section 11 contacts the plate-type pins of the adapter connector to establish a circuit. The pressure spring 2 includes a tail fixing section 20 and a front pressure section 21. The tail fixing section 20 is used to fix it to the tail connecting section 10 of the inner spring 1. The front pressure section 21 presses against the outside of the front contact section 11 from the outside to provide an elastic pressure against the front contact section 11 towards the inside, ensuring reliable contact between the front contact section 11 and the plate pin of the adapter connector.

[0032] The front contact sections 11 of the two inner spring contacts 1 are spaced apart and are generally Y-shaped, forming a mating space 12 between them for the insertion of the plate pins of the adapter connector. After the plate pins are inserted, the front contact sections 11 of the two inner spring contacts 1 contact the two sides of the plate pins. The tail connecting sections 10 of the two inner spring contacts 1 are fitted and fixed, and the edges of the tail connecting sections 10 of the inner spring contacts 1 extend straight outwards with an extension portion 19 for connecting external cables or conductors.

[0033] In this embodiment, the connector's plate socket is fixed by the tail connecting sections 10 of the two inner springs 1, and the front contact section 11 forms a mating space 12. Furthermore, the edge of the tail connecting section 10 of the inner spring 1 extends straight with an extended portion for connecting external cables or conductors. Compared with the prior art, this eliminates the need for copper busbars for wiring, reduces the thickness of the plate socket, and reduces the overall size of the connector.

[0034] Based on the above embodiments, in some embodiments, the extension portion extends perpendicularly to the insertion direction towards one side of the width direction of the tail connecting segment, and the extension directions of the extension portions on the two tail connecting segments are the same; or, the extension portion extends perpendicularly to the insertion direction towards one side of the width direction of the tail connecting segment, and the extension directions of the extension portions on the two tail connecting segments are opposite. Figure 1-3 In the illustrated embodiment, the edge of the tail connecting section 10 extends rearward to form an extension portion 19. The extension portion 19 and the tail connecting section 10 are sheet structures on the same plane. Since the tail connecting sections 10 of the two inner springs 1 are attached and fixed together, the extension portions 19 are also attached together. The opposite sides of the extension portions 19 of the two inner springs 1 are used for connecting external cables, and the specific connection method can be soldering. Since the overall structure formed after the extension portions 19 of the two inner springs 1 are attached is located in the middle of the thickness direction of the plate socket, wiring can be done on either side of the extension portion 19. No error-proofing is required when the plate socket is installed inside the connector housing.

[0035] Based on the above embodiments, in a more preferred embodiment, the outer extension portion 19 of the two inner spring sheets 1 is provided with positioning inserts through a plurality of positioning holes 13 and positioning posts 14. The insertion of the positioning holes 13 and positioning posts 14 ensures reliable contact between the two outer extension portions 19, thus preventing warping and deformation of the outer extension portion 19 when welding cables, which would cause high temperatures during current flow. Specifically, the positioning holes 13 and positioning posts 14 are preferably distributed discretely and uniformly. In one embodiment, the positioning holes 13 and positioning posts 14 are distributed at the edge of the outer extension portion 19. By positioning and inserting at the edge, deformation at the edge, which is prone to warping, can be effectively prevented. Of course, in other embodiments, the positioning insert points can be evenly arranged throughout the entire outer extension portion 19. The positioning hole 13 and the positioning post 14 can be set in different ways. In some embodiments, the positioning hole 13 is set on one of the two extension portions 19, and the positioning post 14 is set on the other of the two extension portions 19. Or in other embodiments, the two extension portions 19 are provided with positioning holes 13 and positioning posts 14 at the same time, so that when they are fastened together, the positioning hole 13 on one side can be inserted into the positioning post 14 on the other side.

[0036] Based on the above embodiments, in a more specific embodiment, the tail fixing section 20 of the pressure spring 2 can be welded to the outer surface of the tail connecting section 10, and the tail connecting sections 10 of the two inner springs 1 are welded together. Figure 1-3 In the illustrated embodiment, the tail fixing section 20 is fitted to the outside of the tail connecting section 10. The inner spring 1 and pressure spring 2 of the two insert plate assemblies are fixedly connected by a connector that passes through both the tail fixing section 20 and the tail connecting section 10, thereby keeping the tail connecting section 10 of the two inner spring 1 and the external connecting end in contact. The connector can be a bolt and nut assembly or a rivet 4. Locking the inner spring 1 and pressure spring 2 of the two insert plate assemblies together with rivets 4 is simpler and cheaper from a manufacturing perspective, and this method is less prone to deformation, making it easier to maintain the shape of the insert plate assembly.

[0037] Based on the above embodiments, in a more specific embodiment, the connector housing includes a rectangular mounting cavity. The edge of the inner spring 1 in the width direction and / or the edge of the outer extension 19 in the width direction are provided with strong barbs facing the tail. The plate-type socket is inserted into the mounting cavity from back to front and is fixed in the mounting cavity by the strong barbs. Figure 1-3 In the illustrated embodiment, the extension portion 19 extends straight backward from the rear edge of the tail connecting section 10. The width of the extension portion 19 is greater than the width of the plug-in assembly on its front side. A forward-facing stop step 5 is formed at the junction of the extension portion 19 and the tail connecting section 10. The pressure spring 2 is provided with a locking claw 22 extending backward and upward. The mounting cavity has a rearward positioning surface. The cavity wall of the mounting cavity corresponding to the pressure spring 2 is provided with a locking groove. When the plate socket is inserted into the mounting cavity from back to front, the stop step 5 and the positioning surface stop and position it. At this time, the locking claw 22 is locked into the locking groove. In this way, the stop step 5 and the positioning surface can prevent the plate socket from moving forward. The cooperation of the locking groove and the locking claw 22 can prevent the plate socket from coming out backward, thereby realizing the fixed installation of the plate socket in the mounting cavity of the connector housing and effectively limiting the amount of deflection of the plate socket in the connector mounting cavity.

[0038] In one embodiment, the locking claws 22 are disposed on both sides of the width direction of the pressure spring, such as... Figure 1-3 In the illustrated embodiment, the locking claw is disposed on one side of the pressure spring in the thickness direction. The number of locking claws can be set as needed, and can be one or more. In the embodiment shown, there is one locking claw on the pressure spring, located at the middle position in the width direction of the pressure spring. Moreover, preferably, the rear end of the locking claw 22 extends above the tail fixing section 20, so that the space between the upper side of the tail fixing section and the upper side of the pressure claw can be utilized.

[0039] In some embodiments, the stop step 5 may also be chamfered or rounded to facilitate mold processing and assembly of the chip socket and connector, while also helping to improve the stability of mass production of the chip socket.

[0040] Based on the above embodiments, a more specific embodiment describes the structure of the inner spring 1 and the pressure spring 2. Both include forward-extending spring arms 3 arranged side by side in the width direction. The number of spring arms 3 on both is equal. The spring arm 3 of the pressure spring 2 presses inward against the corresponding spring arm 3 of the inner spring 1. Its specific structure is similar to that in the prior art and will not be described again here. Of course, in other embodiments, the number of spring arms 3 on the pressure spring 2 may be different from the number of spring arms on the inner spring 1. For example, one spring arm on the pressure spring may have a larger width, thus being able to simultaneously press against two or more spring arms on the inner spring 1.

[0041] The specific structure of the plate socket embodiment of this utility model is the same as that of the plate socket in the connector described above, and will not be repeated here.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
