Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of force detectors, and in particular relates to an insertion and extraction force detector for a CPA connector of an automobile. Background Art
[0002] Automotive connector CPA refers to the secondary locking structure of the connector, which is a snap-on structure that increases the strength of the connector locking device. Its working principle is that when the main locking structure is locked, CPA assists in locking. At this time, the main locking structure will not be easily loosened by the external environment. When unlocking, the CPA needs to be unlocked to unlock normally. This can meet the requirements of a locking structure used under harsh conditions. The insertion and extraction force tester is a device used to detect the force when inserting and removing the connector. By using the insertion and extraction force tester, the operating force of inserting and removing the connector can be quantified to evaluate the performance and user experience of the connector. These instruments are commonly used in automobiles, aerospace, communication technology, medical equipment and other fields that require high reliability, safety and consistency.
[0003] The patent with application number 202211390891.7 discloses a multi-connector plug-in and pull-out force testing machine, which realizes the plug-in of multiple connectors by arranging multiple plug-in connectors on the upper workbench, thereby realizing simultaneous detection of multiple connectors and improving the efficiency of plug-in and pull-out force detection. The setting of the disassembly and assembly components can facilitate the replacement of the plug-in connectors, so that the appropriate plug-in connectors can be selected according to the type of detection cable. However, when using the detector in the application for detection, due to the different shapes of different connectors, if the connector has a certain length and the connector end is irregular, the plug-in and pull-out alignment may be affected during the clamping and plug-in detection, and the plug-in and pull-out process may be tilted and offset, thereby affecting the practicability of the device. For this reason, we propose an automotive connector CPA insertion and pull-out force tester. Utility Model Content

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Example 1
[0022] See also Figure 1 , Figure 2 and Figure 3The utility model provides a technical solution: the function of the automotive wiring harness CPA is to ensure that the buckle of the locking mechanism will not be easily withdrawn after the plastic shell and the electrical interface are assembled in place. During use, a force detector is usually used to detect the insertion and extraction force of the detector. A car connector CPA insertion and extraction force detector includes a detection base 100, a support column 101 is fixedly installed on the top of the detection base 100, a plug-in upper slide 102 is arranged on the top of the support column 101, and a plug-in lower slide 103 is installed on the bottom of the plug-in upper slide 102. An upper clamping seat 104 is fixedly arranged on the bottom of the plug-in upper slide 102. The top of the lower sliding seat 103 is provided with a lower clamping seat 105 corresponding to the upper clamping seat 104, and a retaining frame 200 is also installed on the lower clamping seat 105. A clamping plate 203 is installed on the inner side of the retaining frame 200. A screw 201 is rotatably installed on one end of the clamping plate 203. The screw 201 is installed on the side wall of the retaining frame 200 through a thread. When the screw 201 is rotated, the clamping plate 203 can be driven to move and clamp. At the same time, limiting rods 202 are fixedly installed on both sides of the clamping plate 203, and the limiting rods 202 penetrate the side walls of the retaining frame 200 to play a limiting role, thereby ensuring the stability of the clamping plate 203 during movement and clamping. A clamping plate 203 is provided on the inner side of the clamping plate 203 The inner surface of the clamping plate 203 is provided with a limiting groove 205, and the edge of the clamping block 204 is provided with an integrated limiting protrusion 206. The clamping plate 203 and the clamping block 204 are embedded and installed through the limiting groove 205 and the limiting protrusion 206, which is convenient for the disassembly and assembly of the clamping block 204. When the force detector in the application is used for detection, the two ends of the connector are respectively installed on the upper clamping seat 104 and the lower clamping seat 105 for alignment clamping and fixing. After the connector is installed, if the connector has a certain height, the port of the connector can be auxiliary clamped and fixed by the retaining frame 200. When clamping, the screw 201 is rotated, and the screw 201 drives the inner clamping plate 203 of the retaining frame 200 to move toward each other through the thread, so as to clamp and fix the port of the connector. When clamping, if the fracture of the connector is rectangular, the clamping block 204 can be embedded in the clamping plate 203. The clamping block 204 and the clamping plate 203 are installed in alignment through the limiting protrusion 206 and the limiting groove 205. The clamping stability can be ensured by the clamping block 204 with a planar structure. If the fracture is an arc structure, in order to ensure stable clamping, it can be clamped directly by the clamping plate 203, so as to better ensure the stability of the device during clamping detection, prevent the connector from shaking unsteadily during detection and use, and better measure the force during plugging and unplugging.
[0023] Specifically, the retaining frame 200 is a U-shaped structure, and two groups of clamping plates 203 are symmetrically arranged on the inner side of the retaining frame 200 to better clamp and fix the connector. One side surface of the clamping plate 203 is an arc structure, and one side surface of the clamping block 204 is a flat structure, which is convenient for clamping connectors of different shapes, thereby providing better clamping and fixing.

The fixed and adjustable retaining frame 200 can be raised and lowered for better fixed installation. The upper clamping seat 104 is equipped with a retaining frame 200 with the same structure as that on the lower clamping seat 105. When the device is used to detect different types of connectors, it can also be adjusted according to the height of the connector. When adjusting, loosen the hand bolt 302, adjust the height of the retaining frame 200 by lifting the support rod 300, and then tighten the hand bolt 302 to fix it. The retaining frame 200 with adjustable height can be used for clamping and fixing different types of connector ports, thereby improving the practicality of the device.
