Description

Technical Field

[0001] This utility model relates to the field of plug connector housing production technology, and in particular to a plug connector housing alignment device. Background Technology

[0002] As electronic devices rapidly evolve towards miniaturization and high density, connectors, as core components for circuit signal transmission, directly determine the stability of the entire device through their performance and reliability. Especially in fields such as 5G communication, new energy vehicles, and consumer electronics, connectors must meet stringent requirements such as high-frequency, high-speed transmission, waterproofing, dustproofing, and vibration resistance, which places even higher standards on the precision of housing mating alignment.

[0003] The alignment process of traditional plug-in connector housings mainly relies on manual operation. This approach has the following shortcomings: 1. Insufficient precision: The human eye has limited resolution, especially when aligning micro-connectors (such as 0.4mm pitch board-to-board connectors), the human error rate can be as high as 5% to 10%; 2. Low efficiency: It takes skilled workers more than 30 seconds to complete a single alignment, and their efficiency is prone to fluctuations due to fatigue, making it difficult to meet the cycle time requirements of automated production lines; 3. Poor consistency: Manual operation makes it difficult to ensure the consistency of the alignment angle and pressure each time, which can easily cause damage to the contact surface or deformation of the housing, shortening the service life of the connector.

[0004] To address these issues, some companies have attempted to use semi-automatic alignment devices. For example, Chinese patent CN219394001U discloses a connector housing alignment mechanism. This mechanism mounts two connector housings requiring alignment onto corresponding connector housing carriers. The angle of the carriers is adjusted by a drive motor, and alignment is completed by a cylinder. However, if the two connector housings are misaligned, one of the housings needs to be adjusted by rotating a handle to achieve alignment. While this structure addresses the three shortcomings mentioned above, it still has some drawbacks. For instance, the motor-driven mounting bracket is required to rotate and adjust the angle of the connector housing carrier before fixing it. This necessitates not only the motor but also other components such as a brake to adjust the carrier angle, resulting in high manufacturing and operating costs. Furthermore, when alignment requires adjusting one of the housings by rotating a handle, the cylinder's push may cause the two misaligned housings to collide and be damaged.

[0005] To address this, we designed a low-cost and highly secure connector housing alignment device. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model discloses a plug connector housing alignment device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A connector housing alignment device includes a processing base. The top surface of the processing base is provided with two rotatable mounting plates spaced apart along its length. The processing base is provided with a magnetic vertical positioning block at a position corresponding to the inner side of the mounting plate, which is used to attract the mounting plate and keep it in a vertical state.

[0009] An adjusting shaft is vertically inserted through the outer end of the mounting plate, and the adjusting shaft is connected to the mounting plate in a damped rotational manner. A carrier for fixing the connector housing is provided at the upper end of the adjusting shaft, and a flexible component is sleeved on the shaft body between the mounting plate and the carrier.

[0010] The processing base is also provided with a driving mechanism, which is used to drive at least one mounting plate to move along the length direction of the processing base to achieve the alignment and insertion of the two connector housings.

[0011] Furthermore, the magnetic vertical positioning block includes a base, and the top of the base is provided with a magnetic part that contacts the corresponding mounting plate.

[0012] Furthermore, the base has a recess on the side near the corresponding mounting plate, and a buffer is installed in the recess.

[0013] Furthermore, the top surface of the processing seat is provided with a groove along its length, and at least one sliding block is provided in the groove. The sliding block is fixedly connected to the mounting plate and the corresponding magnetic vertical positioning block.

[0014] Furthermore, the outer end of the mounting plate is provided with a vertical through mounting hole, and a damping sleeve is installed in the cavity of the mounting hole, through which the adjusting shaft passes.

[0015] Furthermore, the mounting hole is a stepped hole, with the section near the vehicle being a large-diameter section, and the damper is sleeved on this large-diameter section.

[0016] Furthermore, the damping sleeve is made of polyurethane or rubber material, and its inner wall forms frictional damping with the adjusting shaft.

[0017] Furthermore, the flexible component is a spring or a silicone sleeve.

[0018] Furthermore, the processing base is provided with a magnetic horizontal positioning block at the position corresponding to the outer side of the mounting plate, which is used to attract the mounting plate and keep it in a horizontal state.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. Due to the design of the mounting plate, as well as the magnetic vertical positioning block and the magnetic horizontal positioning block, the mounting plate can be easily flipped when disassembling and assembling the connector housing, and the vertical and horizontal states of the mounting plate can be fixed by magnetic attraction. Compared with the existing technology that uses motors and other equipment to flip and fix the mounting plate, the manufacturing and operating costs are reduced.

[0021] 2. The buffer component in the magnetic vertical positioning block can buffer the mounting plate when it is flipped to the vertical position, preventing the mounting plate from colliding with the magnetic vertical positioning block and causing the connector housing to shift under inertia, which would affect the alignment and insertion operation and improve the accuracy of the alignment and insertion.

[0022] 3. Due to the flexible component, the connector housing can be prevented from being damaged by compression of the flexible component in case of misalignment. Attached Figure Description

[0031] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

It should be understood that if terms such as "end", "side", "end portion", "side part", "lateral", "longitudinal", etc. indicate orientation or positional relationship, they are only corresponding to the length and width of the corresponding component. That is, "end" indicates the head and tail area in the length direction of the corresponding component, and "side part" indicates the head and tail area in the width direction of the corresponding component. They are used for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation.

[0032] Example 1, in conjunction with Appendix Figure 1-7 A connector housing alignment device, comprising:

[0033] Machining base 1: A groove 11 is provided on the top surface along its length, and a sliding block 12 is installed in the groove 11, with the sliding block 12 slidably connected to the groove 11. Depending on the requirements, the machining base 1 is made of aluminum alloy, and the surface of the groove 11 is hardened to enhance wear resistance. Preferably, a guide shaft is provided in the groove 11, and the guide shaft slides through the sliding block 12.

[0034] Mounting plate 2: There are two, one is a fixed mounting plate 2 that cannot move linearly, and the other is a movable mounting plate 2 that can move horizontally along the slide groove 11. The fixed mounting plate 2 is located at the right end of the machining base 1 and is rotatably connected to the top surface of the machining base 1 by hinges, etc.; the movable mounting plate 2 is rotatably connected to the sliding block 12 and can move horizontally along the slide groove 11.

[0035] Both mounting plates 2 have stepped mounting holes 21 at their outer ends. The section near the carrier 5 is a large-diameter section and is embedded with a polyurethane damping sleeve 22. The adjusting shaft 4 passes through it and forms a damping rotation connection.

[0036] Magnetic vertical positioning block 3: Two blocks are provided, each located inside one of the two mounting plates 2. They are held vertically by magnetic attraction 32. Depending on the requirements, each block includes a base 31, magnetic attraction 32, and a buffer 33 within a recess 311. The magnetic attraction 32 is an electromagnet used to attract the mounting plate 2 and keep it vertical; the buffer 33 is a silicone pad used to reduce the impact when the mounting plate 2 is flipped to a vertical position.

[0037] Specifically, the buffer 33 extends out of the recess 311, and a deformation accommodating space is provided between its top and the inner top surface of the recess 311 to prevent the buffer 33 from shifting between the magnetic suction part 32 and the mounting plate 2 after deformation, thus affecting the verticality of the mounting plate 2.

[0038] Magnetic horizontal positioning block 8: There are two of them, located on the outside of the two mounting plates 2 respectively, for holding the mounting plates 2 in place.

[0039] It should be noted that the magnetic vertical positioning block 3 and the magnetic horizontal positioning block 8 corresponding to the fixed mounting plate 2 are both fixedly installed on the sliding block 12.

[0040] Drive mechanism 7: adopts a stepper motor and ball screw transmission system, the screw is connected to the sliding block 12, and drives the sliding block 12 to move along the slide groove 11.

[0041] Adjusting shaft 4 and carrier 5: The adjusting shaft 4 passes through the damping sleeve 22 and forms a damped rotational connection with the mounting plate 2. The carrier 5 is fixed to the upper end of the adjusting shaft 4 for clamping the connector housing. A spring 6 is sleeved on the shaft body of the adjusting shaft 4 as a flexible element to buffer the axial pressure during insertion and absorb the collision energy during misalignment insertion.

[0042] Operating procedures:

[0043] Initial state: The two mounting plates 2 are respectively attracted by the corresponding magnetic horizontal positioning blocks 8 and kept horizontal.

[0044] Clamping connector housings: Fix the two connector housings onto the carriers 5 of the two mounting plates 2 respectively.

[0045] Drive alignment: Flip the mounting plate 2 upwards, so that the mounting plate 2 changes from being magnetically attracted horizontally to the positioning block 8 to being magnetically attracted vertically to the positioning block 3. Start the drive mechanism 7, and the stepper motor pushes the sliding block 12 through the lead screw to move the corresponding mounting plate 2 to the right along the slide groove 11, closer to the other mounting plate 2.

[0046] When the two connector housings are in the correct position, the alignment and insertion are completed directly. When the two connector housings are in the wrong position, the flexible part 6 is compressed to prevent damage to the two connector housings. Then, the carrier 5 is rotated by rotating the adjusting shaft 4 to make the two connector housings in the correct position.

[0047] Example 2: A connector housing alignment device, which differs from Example 1 in that: two sliding blocks 12 are installed in the slide groove 11, and two mounting plates 2 are slidably connected to the slide groove 11 through the sliding blocks 12 respectively. The lead screw in the drive mechanism 7 is a bidirectional lead screw, which is connected to the two sliding blocks 12 respectively, and is used to drive the mounting plates 2 to move along the slide groove 11 to achieve the alignment of the two connector housings.

[0048] In other embodiments, the flexible element 6 can be a silicone sleeve.

[0049] In other embodiments, the drive mechanism 7 may be a cylinder.

[0050] In other embodiments, the damping sleeve 22 may be a damping sleeve 22 made of rubber material.
