Abstract

This utility model relates to the field of connector manufacturing tools, and more particularly to a connector housing finishing fixture. The connector housing finishing fixture provided by this utility model solves the technical problem that existing fixtures used for clamping connector housings easily damage the connector housing. A connector housing finishing fixture includes a base; clamping arms; and a drive mechanism, wherein the drive mechanism drives the two clamping arms to move closer or further apart. By setting a slide and a clamping block, and providing an elastic element between the clamping block and the slide, the elastic element allows the clamping block to move a certain distance relative to the slide. When clamping the connector housing, the elastic element pushes the clamping block to clamp the connector housing. When the slide continues to move, the elastic element undergoes elastic deformation. At this time, the position of the clamping block relative to the base is fixed and will not move due to the movement of the slide, thereby preventing the connector housing from being damaged or deformed, and optimizing the fixture's performance.

Description

Technical Field

[0001] This utility model relates to the field of tools for connector manufacturing, and in particular to a precision machining fixture for connector housings. Background Technology

[0002] Connectors are commonly used to connect two electronic devices, enabling electrical or communication connections between them. Connectors are widely used due to their simple structure and directional assembly.

[0003] Connectors in the prior art typically include a housing, which is usually made of a metal material, such as aluminum alloy. The connector housing requires finishing during the manufacturing process. In particular, the side walls of the connector housing often require different types of finishing, and since the wall thickness of the connector housing is usually relatively thin, a fixture is used to hold both ends of the connector housing before the outer wall is machined accordingly.

[0004] The existing clamping structures used to hold connector housings are unreasonable, lacking buffering function, and are prone to damaging or deforming the connector housings.

[0005] Therefore, existing clamps used to hold connector housings have the technical problem of easily damaging the connector housings. Utility Model Content

[0006] This utility model provides a connector housing finishing fixture, which solves the technical problem that existing fixtures used to hold connector housings are prone to damaging the connector housings.

[0007] Some implementation schemes for solving the above-mentioned technical problems include:

[0008] A connector housing finishing fixture, including a base;

[0009] The clamping arms are two in number, and both clamping arms are slidably connected to the base.

[0010] and a drive mechanism, which drives the two clamping arms to move closer to or further away from each other;

[0011] The clamping arm includes a slide block slidably connected to the base and a clamping block slidably connected to the slide block, and an elastic element is provided between the clamping block and the slide block to prevent the clamping block from damaging the connector housing;

[0012] The driving mechanism includes a threaded rod rotatably connected to the base. The threaded rod includes a positive thread section and a negative thread section. One of the slides is provided with a positive threaded hole that mates with the positive thread section, and the other slide is provided with a negative threaded hole that mates with the negative thread section.

[0013] Preferably, the slide block is provided with a sliding cavity, and a portion of the clamping block is located within the sliding cavity.

[0014] Preferably, the elastic element includes a first spring located inside the sliding cavity, one end of the first spring being fixed to the clamping block, and the other end of the first spring being fixed to the side wall of the sliding cavity.

[0015] Preferably, the elastic element further includes a second spring, a guide post is provided in the sliding cavity, the clamping block is provided with a guide groove that cooperates with the guide post, one end of the second spring is fixed to the guide post, and the other end of the second spring is fixed to the guide groove.

[0016] Preferably, the clamping block is provided with a convex ring that mates with the sliding cavity, the outer diameter of the convex ring being larger than the outer diameter of the clamping block, and the slide block is further provided with a limiting ring to prevent the convex ring from sliding out of the sliding cavity.

[0017] Preferably, the limiting ring is fixed to the slide block by screws. The limiting ring includes a cylindrical body extending into the slide cavity. The limiting ring also includes a flange disposed on the cylindrical body. The flange is provided with a through hole for installing the screw. The slide block is provided with a screw hole that mates with the screw. The flange and the cylindrical body are an integral structure.

[0018] Preferably, the base is provided with a guide groove, and the slide is provided with a guide block that cooperates with the guide groove.

[0019] Preferably, the guide block and the slide are an integral structure, and the cross-sectional shape of the guide block is a trapezoid that is narrower at the top and wider at the bottom.

[0020] Preferably, the base is provided with a limiting plate that limits the axial position of the threaded rod. There are two limiting plates, and a limiting cavity is formed between the two limiting plates. The threaded rod also includes a limiting part, which is located in the limiting cavity. The limiting plate is provided with a through hole through which the threaded rod passes.

[0021] Preferably, both ends of the threaded rod are provided with handles for easy rotation of the threaded rod, the handles are connected to the threaded rod by a key, and the limiting plate is fixed to the base by screws.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] By setting a slide and a clamping block, and setting an elastic element between the clamping block and the slide, the elastic element allows the clamping block to move a certain distance relative to the slide. When clamping the connector housing, the elastic element pushes the clamping block to clamp the connector housing. When the slide continues to move, the elastic element generates elastic deformation. At this time, the position of the clamping block relative to the base is fixed and will not move due to the movement of the slide, thereby preventing the connector housing from being pinched or deformed, and optimizing the performance of the clamp.

[0024] By incorporating a threaded rod, which includes a forward thread section and a reverse thread section, rotating the threaded rod allows the two clamping arms to move closer or further apart, thus facilitating the operation of the fixture and further optimizing its performance. Since the clamping arm position is driven by the threaded rod, once the clamping arms reach the target position, such as when the connector housing is loosened or clamped, there is no need for a separate locking mechanism to lock the clamping arms, simplifying the fixture's structure and reducing its manufacturing cost.

[0036] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0037] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0038] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0039] Reference Figures 1 to 6 As shown, a connector housing finishing fixture includes a base 1;

[0040] Clamping arms 2, there are two clamping arms 2, and both clamping arms 2 are slidably connected to the base 1;

[0041] and drive mechanism 3, which drives the two clamping arms 2 to move closer to each other or further away from each other;

[0042] The clamping arm 2 includes a slide 21 slidably connected to the base 1 and a clamping block 22 slidably connected to the slide 21. An elastic element is provided between the clamping block 22 and the slide 21 to prevent the clamping block 22 from damaging the connector housing.

[0043] The drive mechanism 3 includes a threaded rod 31 rotatably connected to the base 1. The threaded rod 31 includes a positive thread section 32 and a negative thread section 33. One of the slides 21 is provided with a positive threaded hole 23 that mates with the positive thread section 32, and the other slide is provided with a negative threaded hole that mates with the negative thread section 33.

[0044] Understandably, the threaded rod 31 can rotate relative to the base 1, but cannot be positioned along the axial direction, so that the two clamping arms 2 can move closer or further apart when the threaded rod 31 is rotated.

[0045] The thread pitch of the forward thread segment is equal to that of the reverse thread segment, but the direction is opposite.

[0046] Understandably, rotating the threaded rod 31 brings the two clamping arms 2 closer together, at which point the two clamping blocks 22 clamp the connector housing located between them. Due to different operator habits, the threaded rod 31 often rotates at different angles, which may result in the connector housing being clamped with appropriate force while the threaded rod 31 continues to rotate, meaning the displacement distance of the two clamping arms 2 is too large, causing excessive clamping force applied to the connector housing. However, by incorporating an elastic element, the elastic element clamps the connector housing using elastic force. After the connector housing is clamped with appropriate force, even if the threaded rod 31 continues to rotate, the elastic deformation of the elastic element after the displacement of the slide 21 results in a definite force applied to the connector housing by the clamping blocks 22. Therefore, the connector housing is less likely to be damaged or deformed.

[0047] In some embodiments, the slide block 21 is provided with a sliding cavity 24, and a portion of the clamping block 22 is located within the sliding cavity 24. The clamping block 22 and the sliding cavity 24 have a high connection strength, and the sliding cavity 24 guides the clamping block 22, enabling the clamping block 22 to have higher displacement accuracy relative to the slide block 21.

[0048] The cross-sectional shape of the sliding cavity 24 can be circular or polygonal.

[0049] Reference Figure 3 , Figure 6 As shown, in some embodiments, the elastic element includes a first spring 25 located within the sliding cavity 24, one end of the first spring 25 being fixed to the clamping block 22, and the other end of the first spring 25 being fixed to the side wall of the sliding cavity 24.

[0050] In some embodiments, the elastic element further includes a second spring 26, a guide post 27 is provided in the sliding cavity 24, the clamping block 22 is provided with a guide groove 11 that cooperates with the guide post 27, one end of the second spring 26 is fixed to the guide post 27, and the other end of the second spring 26 is fixed to the guide groove 11.

[0051] The guide post 27 can be integrated with the slide 21. The cross-sectional shape of the guide post 27 can be circular or polygonal.

[0052] In some embodiments, the clamping block 22 is provided with a convex ring 222 that cooperates with the sliding cavity 24. The outer diameter of the convex ring 222 is larger than the outer diameter of the clamping block 22. The slide block 21 is also provided with a limiting ring 28 to prevent the convex ring 222 from sliding out of the sliding cavity 24.

[0053] When the clamping block 22 is a polygon, the outer diameter of the clamping block 22 refers to the diameter of the outer circle of the clamping block 22.

[0054] Understandably, when the cross-sectional shape of the clamping block 22 is polygonal, the clamping block 22 cannot rotate relative to the slide block 21. When the cross-sectional shape of the clamping block 22 is circular, the clamping block 22 can rotate relative to the slide block 21. In this case, the first spring 25 and the second spring 26 only contact the corresponding parts and are not fixed. In practice, whether the clamping block 22 needs to rotate relative to the slide block 21 can be determined according to the requirements of the connector housing finishing.

[0055] Reference Figure 3 , Figure 6 As shown, in some embodiments, the limiting ring 28 is fixed to the slide block 21 by screws. The limiting ring 28 includes a cylindrical body extending into the slide cavity 24. The limiting ring 28 also includes a flange disposed on the cylindrical body. The flange is provided with a through hole for installing the screw. The slide block 21 is provided with a screw hole that mates with the screw. The flange and the cylindrical body are an integral structure.

[0056] There may be multiple screws, with multiple threads evenly distributed around the flange.

[0057] In some embodiments, the base 1 is provided with a guide groove 11, and the slide 21 is provided with a guide block 211 that cooperates with the guide groove 11.

[0058] There may be one or more guide grooves 11. Multiple guide grooves 11 should be arranged in parallel to each other.

[0059] In some embodiments, the guide block 211 and the slide 21 are an integral structure, and the cross-sectional shape of the guide block 211 is a trapezoid that is narrower at the top and wider at the bottom.

[0060] Reference Figures 1 to 6 As shown, in some embodiments, the base 1 is provided with a limiting plate 12 that limits the axial position of the threaded rod 31. There are two limiting plates 12, and a limiting cavity is formed between the two limiting plates 12. The threaded rod 31 also includes a limiting part 34, which is located in the limiting cavity. The limiting plate 12 is provided with a through hole through which the threaded rod 31 passes.

[0061] In some embodiments, both ends of the threaded rod 31 are provided with handles 35 for facilitating rotation of the threaded rod 31. The handles 35 are connected to the threaded rod 31 by a key, and the limiting plate 12 is fixed to the base 1 by screws.

[0062] A thrust bearing can be installed between the limiting part 34 and the limiting plate 12.

[0063] In some embodiments, the handle 35 may be fitted with a rubber sleeve to provide a better user experience.

[0064] In some embodiments, the clamp 22 may be made of a softer material than the connector housing to prevent the clamp 22 from scratching the connector housing.

[0065] In some embodiments, a core post may also be provided between the two clamping blocks 22. The core post is inserted into the connector housing to support the connector housing so that the connector housing is not easily deformed during processing.

[0066] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.

[0067] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine the above embodiments according to their needs to achieve a better application experience.

[0068] When implementing the subject matter technical solution of this utility model, those skilled in the art can obtain other detailed configurations or drawings based on the subject matter technical solution and the accompanying drawings. Obviously, these details are still within the scope of the subject matter technical solution of this utility model without departing from it.
