Description

Technical Field

[0001] The utility model relates to the field of clamp equipment, and more specifically to a connector sheath clamping clamp. Background Art

[0002] In the production process of modern brushless motors, the connector is an important component that connects the three-phase line of the motor with the three-phase output line of the controller. The commonly used connector is the MR-30 series connector, which consists of a connector body and a connector sheath. During the motor production process, employees need to press the connector sheath together with the connector body. The specific operation steps are to first weld the lead to the connector body, and then press the sheath onto the connector body.

[0003] However, this operation is difficult due to the tight fit between the connector body and the sheath, and the small size of the connector. If employees use manual operation, they often feel fatigued due to long-term repetitive work, and their work efficiency is low. At the same time, manual operation has poor stability, which is prone to loose connections, thus affecting the quality of the final product. If employees use tools such as pliers for press-fitting operations, the mechanical force of the pliers can easily damage the connector sheath, causing the sheath to deform or even break, exposing the internal leads. This will not only affect the stability of the connection, but may also cause the motor to short-circuit during subsequent use, posing a safety hazard.

[0004] The current solutions of the prior art are mainly focused on improving the design of the connector and optimizing the production process. For example, the prior art CN201820893673.8 attempts to solve the problem that the cable line is easy to shake during use and creates a gap with the connector by improving the structure of the connector, and locks it by positioning the assembly to reduce the difficulty of assembly. Although the improved design can reduce the difficulty of press-fitting, it may also bring new problems, such as increasing material costs or affecting the electrical performance of the connector. If a complex press-fit fixture is used, although the efficiency is improved, it requires additional equipment investment, the sheath is easily crushed, and the operator's skills are required to be high. Utility Model Content

[0005] The utility model provides a connector sheath clamping fixture to overcome the defects of low press-fitting efficiency and easy crushing of sheaths in the prior art, which has compact press-fitting and high efficiency.

[0006] In order to solve the above technical problems, the technical solution of the utility model is as follows:

[0007] A connector sheath clamping fixture comprises a movable pressing block, a lower die seat, a stopper and a handle; the movable pressing block is connected with the lower die seat, a spring is arranged inside one end of the movable pressing block, and the handle is connected with the lower die seat;

[0008] The stopper is arranged on one side of the lower die base and blocks the other end of the spring and the movable pressing block;

[0009] The movable pressing block and the lower die seat form a groove for placing the connector sheath to be clamped;

[0010] The handle is rotated to compress the spring and drive the movable pressing block to move toward the stop block, thereby clamping the connector sheath.

[0011] Furthermore, the movable pressing block is an L-shaped structure.

[0012] By adopting the above technical solution, the movable pressing block can better realize relative movement with the lower die base in the horizontal direction.

[0013] Furthermore, the movable pressing block is provided with a toothed groove for fixing the connector main body line body.

[0014] By adopting the above technical solution, the wire of the connector body can be fixed by the toothed groove. The design of the toothed groove can improve the clamping force. The toothed groove can evenly distribute the clamping force on the clamped object, reduce local stress concentration, avoid deformation and damage, and enhance the overall stability and durability.

[0015] 1) Increase the contact area: The toothed groove increases the contact area between the pressure block and the clamped object, thereby increasing the clamping force and making the lead or other fixed object more stable;

[0016] 2) Anti-slip effect: The toothed design provides additional friction to prevent the clamped object from sliding or shifting during operation, ensuring processing accuracy and stability.

[0017] Furthermore, the lower die seat is convex and is provided with a stepped boss; a through hole is provided in the stepped boss to cooperate with the movable pressing block;

[0018] The movable pressing block and the stepped boss form a groove for accommodating the connector body and the connector sleeve.

[0019] By adopting the above technical solution, the stepped boss and convex design of the lower die seat can ensure automatic alignment with the movable pressure block, improve the spatial flexibility of the movable pressure block extrusion spring, and provide a placement platform for the connector body during the press-fitting process, thereby reducing the time and error of manual adjustment, improving assembly efficiency and facilitating disassembly and assembly for daily maintenance.

[0020] Furthermore, a slot hole is provided inside one end of the movable pressing block, and the spring is arranged in the slot hole.

[0021] By adopting the above technical solution, the following effects are achieved: 1) Maintaining the stability of the spring: The slot design effectively fixes the position of the spring, so that it remains stable during compression and recovery. The spring is confined to a specific position and will not slide or deflect due to external force or vibration, thereby ensuring that the device maintains consistent performance during operation; 2) Reducing spring wear: By fixing the spring in the slot, wear of the spring caused by friction during operation is avoided. This not only extends the service life of the spring, but also reduces the maintenance frequency and cost of the equipment; 3) Improving the reliability of the device: The spring fixed in the slot can maintain stable compression and recovery action when subjected to external force, thereby ensuring that the movable pressure block can move smoothly and accurately, improving the overall reliability of the device.

[0022] Furthermore, the movable pressing block is provided with a through hole matched with one end of the handle.

[0023] Furthermore, the lower die base is provided with a groove for assembling the handle.

[0024] By adopting the above technical solution, it is possible to achieve: 1) The design of the through hole makes the connection between the handle and the movable pressure block more stable, provides a larger contact surface and higher friction, and prevents the handle from loosening or falling off during operation; 2) The through hole can evenly distribute the force transmitted through the handle, so that the movable pressure block can be stably stressed when operated by the handle, reducing the risk of deformation and damage caused by local stress concentration; 3) Precise operation: After the handle is connected to the movable pressure block through the through hole, the movement path and force of the movable pressure block can be more accurately controlled, ensuring precise clamping and releasing actions during operation, thereby improving the accuracy and consistency of the operation.

[0025] Furthermore, the handle is L-shaped, and a through hole is provided at a corner of the handle.

[0026] Furthermore, the handle is provided with a latch connected to a groove of the lower die base.

[0027] By adopting the above technical solution, the handle can be flexibly rotated, thereby achieving tight press-fitting of the connector body and the connector sleeve.

[0028] Furthermore, the connector sheath clamping fixture further comprises a bottom plate, and the lower surface of the lower die seat is connected to the bottom plate.

[0029] By adopting the above technical solution, the device can be placed and moved smoothly, and the device can be prevented from tilting due to uneven force on the lower die seat during the press-fitting process.

[0030] Compared with the prior art, the beneficial effects of the technical solution of the utility model are:

[0031] The utility model provides a connector sheath clamping fixture, comprising a movable pressing block, a lower die seat, a stopper and a handle; the movable pressing block is connected with the lower die seat, a spring is arranged inside one end of the movable pressing block, and the handle is connected with the lower die seat;

[0032] The stopper is arranged on the lower die seat and blocks the other end of the spring and the movable pressure block; the movable pressure block and the lower die seat form a groove for placing the connector sheath to be clamped;

[0033] The handle is rotated to compress the spring and drive the movable pressing block to move toward the stop block, thereby clamping the connector sheath.

[0034] When in use, the staff puts the connector sheath to be pressed into the connector body, and fixes each wire of the connector body in the toothed groove of the movable pressure block. At the same time, the handle is connected to the lower die seat through a pin, and the staff compresses the spring by pressing the handle down. During the compression of the spring, the handle drives the movable pressure block to be squeezed toward the block. Under the squeeze of the movable pressure block, the connector sheath is successfully matched and connected with the connector body.

[0047] Example 1

[0048] like Figure 1-7 As shown, this embodiment discloses a connector sheath clamping fixture, including a movable pressing block 1, a lower die base 2, a stopper 3 and a handle 5; the movable pressing block 1 is connected with the lower die base 2, a spring 4 is provided inside one end of the movable pressing block 1, and the handle 5 is connected with the lower die base 2;

[0049] The stopper 3 is arranged on one side of the lower die base 2 and blocks the other end of the spring 4 and the movable pressing block 1;

[0050] The movable pressing block 1 and the lower die base 2 form a groove for placing the connector sheath 8 to be clamped;

[0051] The handle 5 is rotated to compress the spring 4 and drive the movable pressing block 1 to move toward the stop block 3, thereby clamping the connector sheath 8.

[0052] The lower die seat 2 is convex and is provided with a stepped boss; a through hole is provided in the stepped boss to cooperate with the movable pressing block 1; the movable pressing block 1 and the stepped boss constitute a groove for placing the connector body 7 and the connector sheath 8.

[0053] The wires of the connector body 7 can be fixed by the toothed grooves. The design of the toothed grooves can improve the clamping force, evenly distribute the clamping force on the clamped object, reduce local stress concentration, avoid deformation and damage, and enhance the overall stability and durability of the device.

[0054] The design of the stepped boss and convex groove of the lower die base 2 can ensure the automatic alignment of the lower die base 2 and the movable pressure block 1, improve the spatial flexibility of the movable pressure block 1 to squeeze the spring 4, and provide a platform for placing the connector body 7 during the press-fitting process of the connector body 7, thereby reducing the time and error of manual adjustment, improving assembly efficiency and facilitating disassembly and assembly for daily maintenance.

[0055] Example 2

[0056] like Figure 1-7 As shown, this embodiment provides a connector sheath clamping fixture, and the technical solution is similar to that of embodiment 1, except that:

[0057] A slot hole is provided inside one end of the movable pressing block 1, and a spring 4 is arranged in the slot hole; the movable pressing block 1 is provided with a through hole matched with one end of the handle 5; and the lower die base 2 is provided with a groove for assembling the handle 5.

[0058] The slot is used to place the spring 4 so that the spring 4 can maintain a stable position during compression and recovery, thereby preventing the spring 4 from sliding or disengaging, and further improving the reliability of the device.

[0059] The handle 5 is connected to the movable pressing block 1 through the through hole, so that the movable pressing block 1 can be controlled more stably, ensuring the accuracy of the movement path and force of the movable pressing block 1 during operation.

[0060] The rotation of the handle 5 in the above technical solution is achieved by manpower. A small drive motor and a control switch can be externally connected to the handle 5 to drive the rotation of the handle through the control switch, thereby improving the pressing efficiency of the device.

[0061] In the specific implementation process, the press-fitting process of the connector is as follows:

[0062] The staff first matches and connects the movable pressing block 1 with the convex groove position of the lower die seat 2, then places the flexibly removable spring 4 in the slot, then assembles the stopper 3 to limit the horizontal movement space of the spring 4, and then connects the handle 5 with the movable pressing block 1 through the through hole;

[0063] When the staff presses the connector sheath 8, they need to first pass the connector sheath 8 through the motor lead and press it into the welding point of the connector body 7, and then press the motor lead of the connector body 7 into the toothed groove of the movable pressing block 1. After the connector body 7 and the connector sheath 8 are connected, they are placed on the stepped boss of the lower mold base 2.

[0064] Finally, the staff compresses the spring 4 by pressing down the handle 5. During the process of compressing the spring 4, the handle 5 drives the movable pressure block 1 to be squeezed in the direction of the stop block 3. Under the squeezing action of the movable pressure block 1, the connector sheath 8 is successfully matched and connected with the connector body 7.

[0065] Example 3

[0066] like Figure 1-7 As shown, this embodiment provides a connector sheath clamping fixture, and the technical solution is similar to that of embodiment 1, except that:

[0067] The connector sheath clamping fixture also includes a bottom plate 6, and the lower surface of the lower die seat 2 is connected to the bottom plate 6, which can realize the stable placement and movement of the device and prevent the device from tilting due to uneven force on the lower die seat 2 during the press-fitting process.

[0068] The handle 5 is L-shaped, and a through hole is provided at a corner of the handle 5 ; a latch is provided in the through hole of the handle 5 to connect with a groove of the lower die base 2 .

[0069] The design of the L-shaped handle 5 can effectively increase the torque, making it easier for the operator to apply force and making it easier to tighten and release the movable pressing block 1. At the same time, the design of the L-shaped handle 5 conforms to ergonomic design, is comfortable to hold, saves more effort during operation, and reduces fatigue on the hands caused by long-term operation.

[0070] The L-shaped handle 5 can also be further replaced by a V-shaped double-handle lever. The fulcrum of the lever is also designed as a through hole that can be connected to the lower mold base 2 through a pin. The middle part of the lever is designed with an arc-shaped short rod extending from the fulcrum. The arc-shaped short rod is connected to the movable pressure block 1. The two ends of the lever can be rotated by the staff to realize the horizontal left and right movement of the movable pressure block 1 on the lower mold base 2.

[0071] The selection of the through hole position at the corner of the handle 5 can better disperse the force application point, ensure uniform force transmission, and avoid deformation or damage of the handle 5 caused by concentrated force. The handle 5 is fixed to the lower die base 2 by a latch, and the connection is tight and reliable, avoiding the problem of the handle 5 loosening or falling off during use, enhancing the stability and reliability of the entire device, and at the same time, the latch connection method improves the convenience of installation and removal of the handle 5, enhances the maintenance efficiency of the equipment, and reduces maintenance time.

[0072] The movable pressing block 1, the lower die seat 2 and the handle 5 can be made of stainless steel, and the baffle 3 and the bottom plate 6 can be made of aluminum. The density of stainless steel and aluminum is relatively low, which can meet the requirements of the press-fit connector body 7 and the connector sheath 8 while reducing the weight of the device and improving the convenience of disassembly and assembly.

[0073] The staff compresses the spring 4 by pressing down the handle 5. During the process of compressing the spring 4, the handle 5 drives the movable pressure block 1 to be squeezed in the direction of the stop block 3. Under the squeezing action of the movable pressure block 1, the connector sheath 8 is successfully fixedly connected with the connector body 7.

[0074] How it works

[0075] The staff puts the connector sheath that needs to be pressed into the connector body, and fixes each wire of the connector body on the movable pressure block. At the same time, the movable pressure block is connected with the lower die seat, and the handle is connected with the lower die seat through a latch. The staff compresses the spring by pressing the handle down. During the compression of the spring, the handle drives the movable pressure block to squeeze in the direction of the block. Under the squeezing action of the movable pressure block, the connector sheath is successfully connected with the connector body. After releasing the handle, the spring resets and drives the movable pressure block back to its original position.

[0076] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
