Description

Technical Field

[0001] This utility model relates to the field of wire harness terminal testing technology, and in particular to a wire harness terminal clamp. Background Technology

[0002] With the rapid development of the new energy industry, miniaturization and integration have become important development directions. All-in-one integrated products, due to their high space utilization and superior system efficiency, are gradually becoming the mainstream trend. In this integrated design, individual modules no longer exist as independent units but are tightly connected to form a complete system. For cost optimization, the power transfer method between modules is also gradually shifting from traditional connector adapters to direct connection schemes using crimp terminal harnesses.

[0003] In the product development and production process, to ensure the reliability of the final integrated product, each module must undergo multiple rigorous performance tests before leaving the factory. Currently, the factory's individual unit testing stage commonly uses screw-fastened adapters as a temporary connection solution, mechanically connecting the product's output wiring harness terminals to the testing equipment via screw tightening. This connection method has revealed several limitations in actual operation: First, the screw tightening process requires precise control of torque parameters. Excessive torque can cause mechanical damage to the plating on the terminal surface, affecting not only the product's appearance but also leading to oxidation of the copper substrate, ultimately affecting the contact thermal resistance stability of the integrated product during long-term use. Insufficient torque, on the other hand, leads to insufficient contact pressure, reducing the effective contact area, causing a decrease in current carrying capacity and abnormal local temperature rise. Second, for products with short wiring harnesses or open structures, frequent screw removal and installation can easily generate metal shavings. These conductive particles pose a risk of falling into the product's interior, potentially causing safety hazards. In addition, there is a possibility of tool slippage during operation, leading to accidental damage to the product. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] like Figures 1-5 As shown, the wire harness terminal clamp provided in this embodiment has an overall structure including a clamping and locking component 100 and a power transmission component 200. The clamping and locking component 100 and the power transmission component 200 are interconnected and work together to achieve fast and reliable clamping and electrical conduction of the wire harness terminal 10.

[0024] The clamping and locking assembly 100 is used to provide controllable clamping force to stably fix the wire harness terminal 10 under test onto the power transmission assembly 200; the power transmission assembly 200 serves as an electrical connection bridge, enabling the fixed wire harness terminal 10 to establish a stable electrical path with external testing equipment, thereby completing subsequent testing or power-on testing tasks.

[0025] Specifically, the clamping and locking assembly 100 includes a driving member 110 and a clamping member 120, and is mounted as a whole via a bracket 130. The bracket 130 is fixed to the power transmission assembly 200, and forms the supporting skeleton of the entire fixture. The driving member 110 is mounted on the bracket 130 and forms a rotatable connection with the bracket 130, allowing the driving member 110 to rotate around the bracket 130 during operation. The clamping member 120 is also hinged to the bracket 130 and can swing around a fulcrum under the action of driving force, thereby realizing the clamping and releasing action of the wire harness terminal 10.

[0026] When the driving component 110 is activated, the driving force is transmitted to the clamping component 120, causing the clamping component 120 to rotate relative to the power transmission component 200. This causes the clamping component 120 to move downward and firmly press the wire harness terminal 10 onto the surface of the power transmission component 200, ensuring sufficient pressure between the contact surfaces and achieving a low-impedance, high-reliability electrical connection.

[0027] Furthermore, the driving component 110 includes a driving screw 111, a driving connection part 112, and a rotating connection part 113. The driving connection part 112 specifically includes a sleeve and a rotating shaft. The end of the sleeve is connected to the rotating shaft, which is rotatably connected to the bracket 130. The sleeve has an internal threaded hole inside, through which the driving screw 111 passes and forms a helical connection with the internal threaded hole. That is, the driving screw 111 can generate linear displacement along its own axis during rotation, converting the rotational motion into a precise and controllable linear propulsion force.

[0028] A rotating connection 113 is connected to one end of the drive screw 111 near the power transmission assembly 200. The rotating connection 113 is specifically a hinge shaft structure, and it is hinged to the connecting rod structure 121 in the clamping member 120. When the drive screw 111 rotates forward, it pushes the rotating connection 113 to move, thereby pulling or pushing the clamping member 120 to rotate around its hinge point with the bracket 130, realizing a lever-type clamping action.

[0029] To facilitate manual operation, the drive component 110 is also equipped with a drive handle 114. The drive handle 114 is fixedly connected to the end of the drive screw 111 away from the rotating connection part 113, located on the outside of the clamp for easy gripping. The user can drive the drive screw 111 to rotate by rotating the drive handle 114, without the need for additional tools, making operation simple, labor-saving, and efficient. The entire clamping process can be adjusted by controlling the number of rotations to regulate the clamping stroke and pressure, providing good controllability and repeatability.

[0030] The clamping member 120 includes a connecting rod structure 121 and a clamping block structure 122. One end of the connecting rod structure 121 is hinged to the bracket 130, forming a rotation fulcrum; the middle part of the connecting rod structure 121 is hinged to the rotating connection part 113, and the driving force of the drive screw 111 acts on the connecting rod structure 121; the other end of the connecting rod structure 121 is connected to the clamping block structure 122. When the drive system is working, the connecting rod structure 121 swings around its connection point with the bracket 130, causing the clamping block structure 122 to press vertically downward onto the surface of the wire harness terminal 10.

[0031] An insulating pad 123 is attached to the side of the clamping structure 122 facing the power transmission component 200. The insulating pad 123 is made of elastic insulating material, such as silicone or polytetrafluoroethylene, which can prevent short circuit risk during the clamping process and distribute pressure evenly through elastic deformation, protecting the surface plating of the wire harness terminal 10 from scratches or crushing, effectively improving product yield.

[0032] The power transmission assembly 200 includes a substrate 210 and a conductive block 220. The substrate 210, serving as a support platform, is made of high-strength insulating material, providing excellent mechanical stability and electrical isolation. A bracket 130 is fixed to the substrate 210, while the conductive block 220 is positioned at a specific location on the surface of the substrate 210 for direct contact with the conductive parts of the wiring harness terminal 10. The conductive block 220 is typically made of a highly conductive metal material (such as a copper alloy) to ensure low contact resistance and a stable connection. The conductive block 220 is mounted on the substrate 210 via bottom embedding or side limiting, and can be further secured by a pressure plate 230.

[0033] To further improve positioning accuracy and connection reliability, the conductive block 220 is provided with an insulating guide post 221. The insulating guide post 221 protrudes from the surface of the conductive block 220 and is used to insert into the terminal hole on the wire harness terminal 10, serving as a pre-positioning and anti-misinsertion function. Correspondingly, the clamping block structure 122 has a through hole 124, the position of which corresponds to the insulating guide post 221, allowing the guide post to pass smoothly through the clamping block structure 122 without interference during the clamping process. This design not only improves assembly alignment efficiency but also keeps the terminal position unchanged during the clamping process, avoiding misalignment that could lead to poor contact.

[0034] In multi-channel applications, two or more conductive blocks 220 can be arranged on the substrate 210, each corresponding to a terminal of different polarity or signal line. To uniformly fix these conductive blocks 220, a pressure plate 230 is provided on the substrate 210. The pressure plate 230 spans multiple conductive blocks 220 and extends into the snap-fit ​​grooves provided on the sidewalls of each conductive block 220, thereby locking all conductive blocks 220 in a predetermined position. The pressure plate 230 and the substrate 210 are connected in a detachable manner, for example, by bolts or screws, which facilitates maintenance and replacement. When it is necessary to adapt to different types or specifications of wire harness terminals 10, simply loosen the screws, remove the pressure plate 230, and the original conductive block 220 can be removed and replaced with a matching new specification conductive block 220, greatly enhancing the versatility and flexibility of the fixture.

[0035] In addition, the power transmission assembly 200 also includes a junction box 240, which is mounted on the bottom of the substrate 210 and fixedly connected to it. The junction box 240 has internal space reserved to accommodate the test wiring harness 20 of external testing equipment. The test wiring harness 20 is introduced from the bottom of the junction box 240 and electrically connected to the bottom pins of the conductive block 220 inside, for example, through soldering, crimping, or spring contact. The design of the junction box 240 concentrates all electrical connections within an enclosed space, which is both aesthetically pleasing and safe. To enhance protection, a protective cover 250 is provided at the bottom opening of the junction box 240. This cover is detachably installed under the junction box 240, effectively covering the connection area between the test wiring harness 20 and the conductive block 220, preventing dust and foreign objects from entering and preventing accidental contact that could cause short circuits or open circuits. It also improves the overall neatness and safety of the structure.

[0036] In summary, this wire harness terminal clamp uses a drive component 110 to move a clamping component 120, achieving automatic clamping of the wire harness terminals 10 via mechanical transmission. This replaces the traditional manual tightening method that relies on screws, ensuring sufficient contact pressure while avoiding terminal damage caused by over-tightening or tool scratching. It is particularly suitable for testing precision connectors sensitive to surface plating. The entire device is compact, easy to operate, and highly versatile, combining excellent electrical performance and mechanical reliability. It can significantly improve testing efficiency and product yield, meeting the demands of modern electronics manufacturing for automated, high-precision testing fixtures.

Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
