Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a tooling fixture for riveting power connector terminals. Background Technology

[0002] Power connectors are widely used in electronic fields such as computers due to their stable electrical performance. They are used to electrically connect chip modules and printed circuit boards to enable the transmission of data and signals between the two.

[0003] Power connectors typically consist of a one-piece insulated body and conductive terminals housed within it. The insulated body has a mating surface and an opposing assembly surface. In use, the insulated body is first soldered to a printed circuit board using the solder balls at one end of the conductive terminals. Then, the chip module is positioned on the mating surface, and the contacts of the power connector's conductive terminals are aligned with the conductive plates of the chip module. This establishes electrical conductivity between the chip module and the printed circuit board.

[0004] In the manufacturing process of power connectors, terminal crimping is one of the key steps. Currently, existing tooling fixtures for crimping power connector terminals are typically only compatible with a single size of power connector, unable to be adjusted for different sizes. Furthermore, the clamping process suffers from instability, difficulty in precise positioning, and poor versatility. These problems lead to positional shifts in the power connector during crimping, affecting crimping quality, reducing product yield, and increasing production costs.

[0005] Therefore, there is an urgent need for a tooling fixture for riveting power connector terminals that can stably clamp, accurately position, and has good versatility. Utility Model Content

[0006] In order to address the technical deficiencies mentioned in the background art, the purpose of this utility model is to provide a tooling fixture for riveting power connector terminals, so as to solve the problems of unstable clamping, inaccurate positioning and poor versatility of existing tooling fixtures in the process of riveting power connector terminals.

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

[0008] A tooling fixture for riveting power connector terminals includes a main base, a gripper assembly for holding the power connector, and a retractable adjustable assembly for controlling the clamping or loosening action of the gripper assembly. The gripper assembly is symmetrically arranged on the main base, and both sides of the gripper assembly are connected to the retractable adjustable assembly in a driving engagement. The retractable adjustable assembly includes an adjusting block, a screw, and a threaded sleeve. The adjusting block is located on both sides of the gripper assembly, and an elastic reset assembly is provided between the adjusting block and the gripper assembly. One end of the screw passes through the adjusting block and is connected to the gripper assembly, and the other end is threadedly connected to the threaded sleeve. By rotating the screw, the adjusting block pushes or pulls the gripper assembly to achieve the clamping or loosening action.

[0009] Preferably, the elastic reset assembly includes a reset spring and a connecting rod. Multiple connecting rods are provided, with one end of each connecting rod threadedly connected to a fixed base and an adjusting block, and the other end of each connecting rod having a hook hole. The two ends of the reset spring are hooked onto the hook holes.

[0010] Preferably, the screw is also provided with a handle for easy rotation, and the handle is one of round, square or hexagonal.

[0011] Preferably, the main body base has a block structure and is provided with multiple mounting holes for mounting the gripper assembly and the telescopic adjustment assembly; the top and bottom of the main body base are both flat, and the sides of the main body base are provided with interfaces for connecting to external devices.

[0012] Preferably, the gripper assembly includes at least two grippers and a fixed base. The grippers and the fixed base are integrally formed, and the grippers are arranged perpendicular to the fixed base. A sliding component is provided between the bottom end of the fixed base and the main body base. The fixed base is fixedly connected to the sliding component by bolts.

[0013] Preferably, each of the grippers has a gripping surface adapted to the shape of the power connector, and the side of the gripper near the gripping surface is provided with an anti-slip texture.

[0014] Preferably, the clamping surface is planar or arc-shaped.

[0015] Preferably, the sliding assembly includes a linear slide rail and a slider. The linear slide rail is arranged along the length direction of the main body base and is fixedly connected to the main body base. The slider is slidably connected to the linear slide rail, and one end of the slider is connected to the fixed base.

[0016] In summary, the beneficial effects of this utility model are as follows:

[0017] When clamping and fixing power connectors, the clamping jaw assembly holds the power connector, and the telescopic adjustment component accurately adjusts it to the appropriate position according to the power connector of different sizes. This allows for precise control of the clamping and releasing actions of the clamping jaw assembly, ensuring accurate positioning of the power connector terminal riveting, improving riveting quality and product qualification rate. In addition, the elastic reset component not only enables the automatic reset of the clamping jaw assembly, but also provides elastic buffering during the clamping process of the power connector, preventing the clamping jaw assembly from applying excessive rigid pressure to the power connector, preventing damage to the power connector surface or internal structure, and protecting the product quality of the power connector.

[0028] The following is in conjunction with the appendix Figure 1-5 The present invention provides a more detailed description of an embodiment of a tooling fixture for riveting terminals of a power connector.

[0029] A tooling fixture for riveting power connector terminals includes a main base 1, a gripper assembly 2 for holding the power connector, and a telescopic adjustment assembly 3 for controlling the clamping or loosening action of the gripper assembly 2. The gripper assembly 2 is symmetrically arranged on the main base 1, and both sides of the gripper assembly 2 are connected to the telescopic adjustment assembly 3 in a transmission engagement. The telescopic adjustment assembly 3 includes an adjustment block 31, a screw 32, and a screw sleeve 33. The adjustment block 31 is located on both sides of the gripper assembly 2, and an elastic reset assembly 4 is also provided between the adjustment block 31 and the gripper assembly 2. One end of the screw 32 passes through the adjustment block 31 and is connected to the gripper assembly 2 in a cooperating connection, and the other end is threadedly connected to the screw sleeve 33. By rotating the screw 32, the adjustment block 31 pushes or pulls the gripper assembly 2 to achieve the clamping or loosening action.

[0030] Specifically, the adjusting block 31 has a through hole for the screw 32 to pass through, and the inner diameter of the through hole matches the outer diameter of the screw 32, ensuring that the screw 32 can rotate smoothly within the through hole. The screw sleeve 33 is fixedly installed on the main body base 1, and its internal thread matches the thread of the screw 32. One end of the screw 32 passes through the adjusting block 31 and establishes a transmission connection with the gripper assembly 2. Specifically, the connection between the screw 32 and the gripper assembly 2 can be achieved by setting a corresponding threaded hole on the fixed base 22 of the gripper assembly 2, into which the screw 32 is screwed; or by using connecting parts such as pins and keys to circumferentially fix the screw 32 and the gripper assembly 2, so that when the screw 32 rotates, it can drive the gripper assembly 2 to produce linear motion. Through the precise transmission between the screw 32 and the adjusting block 31 of the telescopic adjustment component 3, the clamping and releasing actions of the gripper component 2 can be precisely controlled, thereby accurately adjusting the gripper component 2 to the appropriate position, ensuring the precise positioning of the power connector terminal riveting, and improving the riveting quality and product qualification rate.

[0031] In this embodiment, as Figure 2 , 3 As shown, the elastic reset assembly 4 includes a reset spring 41 and a connecting rod 42. Multiple connecting rods 42 are provided. One end of each connecting rod 42 is threaded to the fixed base 22 and the adjusting block 31, and the other end of the connecting rod 42 is provided with a hook hole 421. Both ends of the reset spring 41 are hooked onto the hook hole 421.

[0032] Specifically, when the screw 32 rotates, causing the adjusting block 31 to push the gripper assembly 2 to clamp the power connector, the return spring 41 is stretched or compressed, thereby storing elastic potential energy. When the screw 32 rotates in the opposite direction, the return spring 41 releases its elastic potential energy. When the gripper assembly 2 needs to be released, the return spring 41 releases the previously stored elastic potential energy and pulls the adjusting block 31 through the connecting rod 42, thereby causing the gripper assembly 2 to reset and release. This elastic reset mechanism not only makes the release action of the gripper assembly 2 smoother and more convenient, but also plays an elastic buffering role in the process of the gripper assembly 2 clamping the power connector, avoiding the gripper assembly 2 from applying excessively rigid pressure to the power connector, and effectively protecting the surface and internal structure of the power connector from damage.

[0033] To facilitate manual rotation of the screw 32 by the operator, such as Figure 1 As shown, a handle for easy rotation is also provided on the screw 32. The handle is one of round, square or hexagonal.

[0034] Specifically, operators can use tools such as wrenches and sockets in conjunction with the handle to easily rotate the screw 32, thereby opening and closing the gripper assembly 2. Furthermore, when the screw 32 rotates in the opposite direction, the return spring 41 of the elastic reset assembly 4 can quickly push the gripper assembly 2 to reset and release, eliminating the need for additional complex operations, greatly shortening the clamping and disassembly time, and improving work efficiency.

[0035] In this embodiment, as Figure 1 and Figure 5 As shown, the main base 1 has a block structure and multiple mounting holes 11 are provided on the main base 1. The mounting holes 11 are used to install the gripper assembly 2 and the telescopic adjustment assembly 3. The top and bottom of the main base 1 are both flat, and the side of the main base 1 is provided with an interface 12 for connecting to external devices.

[0036] Specifically, the main body base 1 is placed on a workbench or other predetermined installation position, and is firmly fixed to the workbench by bolts passing through the mounting holes 11 at the bottom of the main body base 1, ensuring that the main body base 1 will not shift during subsequent operations. At the same time, the tooling fixture can be connected and work in coordination with other devices through the interface 12 on the side of the main frame, thereby quickly completing the terminal riveting work.

[0037] In this embodiment, as Figure 3 As shown, the gripper assembly 2 includes at least two grippers 21 and a fixed base 22. The grippers 21 and the fixed base 22 are integrally formed, and the grippers 21 are set perpendicular to the fixed base 22. A sliding component 5 is provided between the bottom end of the fixed base 22 and the main body base 1. The fixed base 22 is fixedly connected to the sliding component 5 by bolts.

[0038] Specifically, the gripper 21 and the fixed base 22 are manufactured using an integral molding process, which effectively ensures structural strength and stability. Simultaneously, each gripper 21 has a clamping surface 211 adapted to the shape of the power connector, and the side of the gripper 21 closest to the clamping surface 211 is provided with anti-slip texture 212. The clamping surface 211 can be flat, curved, or other specific shapes. When the gripper 21 clamps the power connector, the anti-slip texture 212 effectively increases friction, ensuring that the power connector does not slip within the gripper 21, thus laying a solid and stable foundation for subsequent terminal crimping operations.

[0039] Depending on the shape characteristics of different power connectors, the clamping surface 211 can be flat (suitable for power connectors with regular shapes), arc-shaped (suitable for power connectors with circular or arc-shaped contours), or other specific shapes (such as special shapes designed specifically for irregularly shaped power connectors). On the side of the jaws 21 near the clamping surface 211, anti-slip textures 212, such as knurling or etching, are provided through machining or surface treatment processes to increase the friction between the jaws 21 and the power connector.

[0040] In this embodiment, as Figure 5 As shown, the sliding assembly 5 includes a linear slide rail 51 and a slider 52. The linear slide rail 51 is arranged along the length direction of the main body base 1 and is fixedly connected to the main body base 1. The slider 52 is slidably connected to the linear slide rail 51, and one end of the slider 52 is connected to the fixed base 22.

[0041] Specifically, the slider 52 cooperates with the linear slide rail 51 to slide smoothly on the linear slide rail 51, and one end of the slider 52 is connected to the fixed base 22 by a bolt. This design allows the gripper assembly 2 to be positioned on the main body base 1 along the direction of the linear slide rail 51 to accommodate power connectors of different lengths.

[0042] The working process of this utility model is as follows:

[0043] Clamping Preparation: When crimping the terminals of the power connector, first adjust the position of the clamp assembly 2 on the linear slide rail 51 according to the shape and size of the power connector, so that the distance between the clamps 21 can roughly accommodate the power connector. For example, if the power connector is long, the clamp assembly 2 can be moved appropriately towards both ends of the linear slide rail 51 to increase the distance between the clamps 21; if the power connector is short, the clamp assembly 2 can be moved towards the middle to reduce the distance. At the same time, check whether the return spring 41 of the elastic return assembly 4 is in a normal state to ensure that it can perform its elastic return function normally.

[0044] Clamping the power connector: The operator uses a tool (such as a wrench, socket, etc.) or holds the handle 5 directly by hand and rotates the screw 32 clockwise. Due to the threaded transmission relationship between the screw 32 and the threaded sleeve 33, the screw 32 moves axially while rotating. The movement of the screw 32 causes the adjusting block 31 to move closer to the gripper assembly 2. The adjusting block 31 pushes the gripper assembly 2 to overcome the elastic force of the return spring 41, causing the gripper 21 to rotate around the connection point with the fixed base 22, and the gripper 21 gradually closes. During this process, the return spring 41 is stretched or compressed, storing elastic potential energy. When the clamping surface 211 of the gripper 21 is tightly attached to the surface of the power connector and a suitable clamping force is applied, the rotation of the screw 32 is stopped. At this time, the gripper 21 stably clamps the power connector, preparing for the subsequent terminal riveting operation.

[0045] Terminal riveting operation: After the power connector is clamped and fixed, the tooling fixture is connected to the riveting equipment. The riveting equipment is started through the external control system, so that the riveting head performs the riveting operation on the terminals of the power connector according to the predetermined process parameters (such as riveting pressure, stroke, speed, etc.). During the riveting process, the gripper assembly 2, due to the constraint of the return spring 41 and the screw 32, can maintain a stable grip on the power connector, preventing the power connector from shifting or shaking, and ensuring the accuracy and quality of terminal riveting.

[0046] Removing the power connector: After the terminal riveting operation is completed, the operator rotates the screw 32 counterclockwise. As the screw 32 rotates in the opposite direction, it moves axially in the opposite direction within the screw sleeve 33. Under the action of the elastic potential energy of the return spring 41, the adjusting block 31 moves away from the gripper assembly 2. The return spring 41 pulls the adjusting block 31 through the connecting rod 42, thereby driving the gripper assembly 2 to reset. The gripper 21 rotates in the opposite direction around the connection point with the fixed base 22, and the gripper 21 gradually opens. When the gripper 21 opens to a sufficiently large gap, allowing easy removal of the power connector, the rotation of the screw 32 is stopped. At this point, the operator can remove the riveted power connector from between the grippers 21, completing one cycle of power connector terminal riveting.

[0047] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
