Description

Technical Field

[0001] This utility model relates to the field of connector housing processing tools, and in particular to a connector housing tooling fixture. Background Technology

[0002] Connectors are used to connect two electronic devices and transmit current or signals between them. A connector typically consists of a connector housing and electronic components housed within the housing. These electronic components are usually connected to a cable to enable the transmission of current or signals.

[0003] In the existing technology, after the electronic components are assembled into the connector housing during the assembly process, the cables need to be soldered to the electronic components. During the soldering process, the operator needs to hold the connector housing with electronic components, the cables, and the soldering tool. In practice, two people are needed to complete the soldering operation. In addition, two people need to work together to complete the connection of the connector, which makes the connector soldering inconvenient and the labor intensity of the operators high.

[0004] Therefore, there is a technical problem in the prior art that the connector shell cannot be positioned when soldering connectors. Utility Model Content

[0005] This utility model provides a connector housing tooling fixture, which solves the technical problem of being unable to position the connector housing during connector welding in the prior art.

[0006] Some implementation schemes for solving the above-mentioned technical problems include:

[0007] A connector housing tooling fixture, including a base;

[0008] A clamping cylinder, which is fixed to the base;

[0009] A drive cylinder is sleeved outside the clamping cylinder, and the drive cylinder drives the clamping cylinder to clamp the connector housing;

[0010] A drive mechanism is disposed on the base, and the drive mechanism clamps or releases the connector housing by driving the drive cylinder to displace relative to the clamping cylinder;

[0011] The clamping cylinder includes multiple elastic clamping arms, which together form a clamping cavity. There is a gap between two adjacent elastic clamping arms that communicates with the clamping cavity. The inner cavity of the driving cylinder is a frustum shape that is larger at the top and smaller at the bottom. By positioning the driving cylinder at different positions relative to the elastic clamping arms, the elastic clamping arms can be released or clamped onto the connector housing.

[0012] The drive cylinder also includes a positioning seat for positioning the connector housing relative to the height of the clamping cylinder. The positioning seat is disposed on the drive cylinder via a connecting rod that passes through the gap.

[0013] Preferably, the lower end face of the drive cylinder is an inclined surface, and the base is slidably provided with a drive block. The drive block has a drive surface that cooperates with the inclined surface, and the drive surface drives the drive cylinder by changing the position of contact with the inclined surface.

[0014] Preferably, the driving mechanism includes a lead screw that drives the driving block to move, the driving block is provided with a screw hole that cooperates with the lead screw, and the lead screw is rotatably connected to the base.

[0015] Preferably, the base is provided with a vertical plate for mounting the lead screw, the vertical plate and the base are an integral structure, the lead screw rotates on the vertical plate, and a handle is provided at the end of the lead screw away from the drive block.

[0016] Preferably, the upright plate is provided with mounting holes for mounting the lead screw, the lead screw is mounted in the mounting holes via a deep groove ball bearing, the outer ring of the deep groove ball bearing is interference-fitted with the mounting holes, and the inner ring of the deep groove ball bearing is interference-fitted with the lead screw.

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

[0023] By incorporating a clamping cylinder and a driving cylinder, precise positioning of the connector housing is achieved. The elastic clamping arms of the clamping cylinder, under the action of the driving cylinder, firmly hold the connector housing, preventing displacement or wobbling during welding. Simultaneously, the positioning seat on the driving cylinder further ensures the accurate height of the connector housing within the clamping cylinder, making welding operations more convenient and efficient. Operators no longer need to manually adjust the position of the connector housing, significantly improving work efficiency.

[0024] With the use of tooling fixtures, operators no longer need to hold the connector housing for extended periods while soldering, significantly reducing labor intensity. Operators can then focus more on the soldering operation itself, improving soldering quality and accuracy. Furthermore, the use of tooling fixtures reduces direct contact between operators and the solder joints, lowering safety risks such as burns and improving overall operational safety.

[0025] The precise positioning function of the tooling fixtures ensures the stability of the connector housing during welding, thereby improving welding quality. Welding points are more accurate and robust, reducing welding defects and defective products. Simultaneously, the use of tooling fixtures makes welding operations more standardized and consistent, effectively controlling differences in welding quality between different operators.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] Reference Figures 1 to 6 As shown, a connector housing tooling fixture includes a base 1;

[0041] Clamping cylinder 2, the clamping cylinder 2 being fixed to the base 1;

[0042] A drive cylinder 3 is sleeved outside the clamping cylinder 2, and the drive cylinder 3 drives the clamping cylinder 2 to clamp the connector housing;

[0043] A drive mechanism 31 is disposed on the base 1. The drive mechanism 31 drives the drive cylinder 3 to move relative to the clamping cylinder 2 to clamp or release the connector housing.

[0044] The clamping cylinder 2 includes multiple elastic clamping arms 21, which together form a clamping cavity 22. There is a gap 23 between two adjacent elastic clamping arms 21 that communicates with the clamping cavity 22. The inner cavity of the driving cylinder 3 is a frustum shape with a larger upper part and a smaller lower part. By positioning the driving cylinder 3 at different positions relative to the elastic clamping arms 21, the elastic clamping arms 21 can be released or clamped onto the connector housing.

[0045] The drive cylinder 3 also includes a positioning seat 32 for positioning the connector housing relative to the height of the clamping cylinder 2. The positioning seat 32 is disposed on the drive cylinder 3 via a connecting rod 33, which passes through the gap 23.

[0046] Specifically, when the drive mechanism 31 pushes the drive cylinder 3 upward, the drive cylinder 3 causes the elastic clamping arm 21 to deform, thereby clamping the connector housing for easy operation. When the elastic clamping arm 21 is not under force, the shape of the clamping cavity 22 can be a frustum shape, which is larger at the top and smaller at the bottom, to facilitate the connector housing entering the clamping cavity 22.

[0047] After the welding operation is completed, the drive cylinder 3 is moved downward. At this time, the positioning seat 32 moves downward together with the drive cylinder 3. The positioning seat 32 can open the elastic clamping arm 21 to release the connector housing.

[0048] Understandably, when the drive cylinder 3 moves downward, the elastic clamping arm 21 can also release the connector housing by utilizing its own elastic deformation capability.

[0049] Reference Figures 1 to 6 As shown, in some embodiments, the lower end face of the drive cylinder 3 is an inclined surface, and the base 1 is slidably provided with a drive block 311. The drive block 311 has a drive surface that cooperates with the inclined surface, and the drive surface drives the drive cylinder 3 by changing the position of contact with the inclined surface.

[0050] In some embodiments, the drive mechanism 31 includes a lead screw 312 that drives the drive block 311 to move. The drive block 311 is provided with a screw hole that cooperates with the lead screw 312. The lead screw 312 is rotatably connected to the base 1.

[0051] In some embodiments, the base 1 is provided with a vertical plate 313 for mounting the lead screw 312. The vertical plate 313 and the base 1 are integral structures. The lead screw 312 rotates on the vertical plate 313. A handle 3121 is provided at the end of the lead screw 312 away from the drive block 311.

[0052] A rib can be provided between the upright plate 313 and the base 1. The handle 3121 can be installed on the lead screw 312 via a key connection.

[0053] In some embodiments, the upright plate 313 is provided with a mounting hole for mounting the lead screw 312. The lead screw 312 is mounted in the mounting hole via a deep groove ball bearing. The outer ring of the deep groove ball bearing is interference-fitted with the mounting hole, and the inner ring of the deep groove ball bearing is interference-fitted with the lead screw 312.

[0054] Reference Figures 1 to 6 As shown, in some embodiments, the positioning seat 32 includes an upper seat 321 and a lower seat 322, the lower seat 322 is mounted on the connecting rod 33, and the upper seat 321 is mounted on the lower seat 322 via a height adjuster.

[0055] In some embodiments, the upper seat 321 is provided with a stud 3211, and the lower seat 322 is provided with a threaded hole that mates with the stud 3211. The stud 3211 is also provided with a locking nut 3212 that locks the stud 3211 into the threaded hole. The height of the upper seat 321 relative to the lower seat 322 can be adjusted by changing the engagement length between the stud 3211 and the threaded hole.

[0056] The stud 3211 can be integrated with the upper seat 321. A cylindrical body can be provided in the lower seat 322, and the screw hole is provided in the inner wall of the cylindrical body, so that the stud 3211 and the screw hole have a longer engagement length, and there is no need to thicken the lower seat 322.

[0057] Reference Figures 1 to 6 As shown, in some embodiments, the clamping cylinder 2 is disposed on the base 1 via a support rod 11, and the driving block 311 is provided with a notch to prevent interference with the support rod 11.

[0058] The cross-sectional shape of the support rod 11 can be polygonal, and the drive cylinder 3 can be provided with a through hole that mates with the support rod 11 to prevent the drive cylinder 3 from rotating.

[0059] In some embodiments, a connecting ring is provided at the lower end of the elastic clamping arm 21, and the elastic clamping arm 21 and the connecting ring are integral structures. The lower ends of all the elastic clamping arms 21 are provided on the connecting ring, and the connecting ring and the elastic clamping arm 21 together constitute the clamping cylinder 2.

[0060] The number of elastic clamping arms 21 is not limited. When the cross-sectional shape of the connector housing is a regular polygon, each sidewall of the connector housing corresponds to one elastic clamping arm 21.

[0061] In some embodiments, the clamping cylinder 2 is shaped like a frustum, wider at the top and narrower at the bottom.

[0062] The outer wall of the clamping cylinder 2 is a frustum shape, wider at the top and narrower at the bottom, and the inner cavity of the clamping cylinder 2, i.e., the clamping cavity 22, is also a frustum shape, wider at the top and narrower at the bottom. This allows the elastic clamping arm 21 to clamp the connector housing when the drive cylinder 3 moves upward. When the drive cylinder 3 moves downward, the elastic clamping arm 21 can be opened using the positioning seat 32.

[0063] Understandably, the height of the upper end of the drive cylinder is lower than the height of the lower end of the upper seat.

[0064] 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.

[0065] 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.

[0066] 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.
