Description

Technical Field

[0001] The utility model relates to the technical field of terminal testing fixtures, in particular to a fixture for testing a terminal pressing device. Background Art

[0002] Automotive wiring harness terminals are key components that connect harness wires and connectors to establish conductive connections and ensure reliable transmission of signals and currents. Automotive wiring harness terminals are usually used with specific connectors to ensure correct plugging and connection and provide reliable electrical connections. When designing and manufacturing wiring harnesses, it is necessary to select appropriate wiring harness terminals according to the requirements of the wiring harness and connector to ensure the reliability and stability of the entire wiring harness system.

[0003] Automotive wiring harness terminals can be connected to wires by crimping, welding or plugging. Different connection methods are suitable for different applications and requirements, but they all need to ensure a strong and reliable electrical connection, that is, the crimping part of the harness terminal conductor must be completely closed and contain all core wires, without any core wire leakage, and the conductor end must be flush. Existing test equipment requires the outer layer of the harness terminal to be stripped and then connected to the corresponding test equipment for testing. The overall test takes a long time, which seriously slows down the small batch production test process. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0025] like Figure 1-Figure 3 As shown, in one embodiment, a test fixture for testing a terminal clamping device includes: a support base 1, a test end 2 is symmetrically arranged in the middle of the upper end surface of the support base 1, and the test end 2 includes a first abutment column 21 and a second abutment column 22. The two abutment columns are used to test the compression by abutting against the wiring harness terminal. Specifically, the support base 1 and the test end 2 are integrally formed, and the material of the support base 1 and the test end 2 is an aluminum plate.

[0026] Furthermore, fixing holes 11 are symmetrically provided on both sides of the support base 1, and these fixing holes 11 are used to fix the support base 1 on the test table by bolts to ensure stability and safety during testing. Anti-skid grooves 12 are provided at the edges of the support base 1, and these anti-skid grooves 12 are designed to enhance the friction when the operator holds it, thereby improving the stability and safety of the operation.

[0027] like Figure 1-Figure 3 As shown, in this embodiment, the first abutment column 21 extends upward from the end surface of the support seat 1 to connect with the second abutment column 22. The first abutment column 21 is in a flat key shape, and the second abutment column 22 is in a semicircular shape. Specifically, the height of the first abutment column 21 is at least twice the height of the support seat 1. The height of the second abutment column 22 is greater than or equal to the height of the first abutment column 21.

[0028] Furthermore, an abutment groove 23 is provided at the center of the top of the second abutment column 22, and the abutment groove 23 is used to accommodate the end of the wiring harness terminal. Specifically, the distance between the abutment groove 23 and the straight edge of the second abutment column 22 is 0-1 mm, and the depth of the abutment groove 23 is 1-2 mm.

[0029] Working principle: A test end 2 is symmetrically arranged in the middle of the upper end surface of the support seat 1, and the test end 2 includes a first abutment column 21 and a second abutment column 22. The operator can hold or fix the wiring harness terminal to abut the test end 2 for testing. During the abutment process, the flatness of the abutment is observed to determine whether the compression of the terminal meets the standard requirements. In order to improve efficiency, the test process is divided into two steps: first test a part of the terminals, then rotate the wiring harness 180°, and test the remaining terminals through the other test end 2. This method can not only ensure the accuracy of the test, but also avoid damage to the terminals, and effectively improve the detection efficiency when processing small batches of terminals.

[0030] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
