Description

Technical Field

[0001] This application relates to the field of wire harness testing technology, and in particular to a wire harness sequence determination device. Background Technology

[0002] With the rapid development of electronic devices, accurate testing of terminal wiring sequence has become a crucial step in ensuring product quality, especially in fields such as automotive electronics, home appliances, and communication equipment, where the accuracy of terminal wiring sequence directly affects product performance and safety.

[0003] Existing wire sequence testing instruments typically include a main body and a reader arranged inside the main body. The area on the main body directly below the reader is designated as the wire harness terminal placement and testing area.

[0004] The testing area is typically equipped with slots, plates, or blocks to constrain the placement of wire harness terminals within a certain range, thereby improving testing accuracy. However, wire harness terminals come in many sizes, and the aforementioned slots, plates, or blocks are usually not suitable for the precise positioning of multiple sizes of wire harness terminals simultaneously, which is a significant drawback. Utility Model Content

[0005] To improve the applicability of testing wire harness terminals of different sizes, this application provides a wire harness sequence determination device.

[0006] The wire harness sequence determination device provided in this application adopts the following technical solution: A wire harness sequence determination device includes a body and an identifier located inside the body. A positioning reflector is placed on the body below the identifier. The positioning reflector has a positioning slot for placing wire harness terminals. A locking member is arranged on the body to lock the position of the positioning reflector.

[0007] By adopting the above technical solution, workers manually adjust the position of the positioning backing plate and then lock it in place using locking components. During testing, wire harness terminals of different sizes can be placed in the positioning slots, thereby improving applicability.

[0008] Optionally, the positioning backing plate has an adjustment groove along its adjustment direction, and the locking element includes a fastening bolt threaded onto the frame. The fastening bolt is located in the adjustment groove and is used to press against the positioning backing plate.

[0009] By adopting the above technical solution, workers can loosen the fastening bolts, then manually adjust the position of the positioning backing plate, and then tighten the fastening bolts again to press it firmly onto the positioning backing plate, which is convenient to operate.

[0010] Optionally, a groove is provided on the positioning reflector plate at a position relative to the positioning slot, and a reflector plate is inserted into the groove.

[0011] By adopting the above technical solution, when inspecting wire harness terminals of different sizes, workers can manually change the substrate, so that the color of the substrate is clearly different from the color of each wire in the wire harness, which helps to improve the accuracy of the identifier in identifying each wire.

[0012] Optionally, the machine body is provided with a lifting groove and a support groove communicating with the lifting groove along the adjustment direction of the positioning backing plate. A bottom strip slides vertically in the lifting groove, and a support arm slides vertically in the support groove. The support arm is connected to the bottom strip. The locking member includes a column head that slides vertically through the positioning backing plate. An elastic suction cup is arranged at the bottom of the column head and fastens to the machine body. The bottom strip passes through the elastic suction cup.

[0013] By adopting the above technical solution, the worker manually presses the column head, squeezing out the air between the elastic suction cup and the machine body, thus adhering it to the machine body. During adjustment, the worker presses down on the support arm, which moves the bottom strip downwards, allowing air to enter the elastic suction cup from the support groove and lifting groove, releasing the negative pressure adsorption state, making operation convenient.

[0014] Optionally, the machine body is provided with a guide groove, and the positioning reflector plate extends into the guide groove and slides therein.

[0015] By adopting the above technical solution, the guide groove plays a guiding role in the sliding adjustment of the positioning reflector plate on the machine body.

[0016] Optionally, the machine body is connected to a vertical rod relative to the bottom wall of the support groove, the support arm is slidably sleeved on the vertical rod, and an elastic ball supporting the support arm and the bottom wall of the support groove is also slidably sleeved on the vertical rod.

[0017] By adopting the above technical solution, the elastic ball pushes the bottom strip to achieve reset, which is conducive to the smooth formation of a closed space between the elastic suction cup and the body.

[0018] Optionally, the support arm and the vertical rod are fitted with a clearance.

[0019] By adopting the above technical solution, it is beneficial to improve the smoothness of the lifting and lowering of the outrigger on the vertical pole.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The worker manually adjusts the position of the positioning backing plate, and then locks it in place using locking devices. During testing, wire harness terminals of different sizes can be placed in the positioning slots, thus improving applicability; 2. The worker manually presses the column head, squeezing out the air between the elastic suction cup and the machine body, thus adhering it to the machine body. During adjustment, the worker presses down on the support arm, which moves the bottom strip downwards, allowing air to enter the elastic suction cup from the support groove and lifting groove, releasing the negative pressure adsorption state. Operation is convenient. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] This application discloses a wire harness sequence determination device.

[0027] Example 1 Reference Figure 1 and Figure 2 The wire harness sequence determination device includes a body 1 and an identifier installed inside the body 1. A positioning reflector 3 is placed on the body 1 below the identifier 2. The positioning reflector 3 has a positioning slot 31 for placing the wire harness terminals.

[0028] Reference Figure 1 and Figure 2 A groove 32 is provided on the positioning reflector plate 3 at a position relative to the positioning slot 31, and a reflector plate 5 is inserted into the groove 32.

[0029] Since the identifier 2 determines whether the wire sequence is accurate by recognizing the color of the wires, the worker manually replaces the substrate 5 with different colors so that the color of the substrate 5 is clearly distinguishable from the color of each wire in the wire harness, reducing the possibility that the identifier 2 will make a mistake due to similar colors.

[0030] Reference Figure 1 and Figure 2 The machine body 1 is provided with a locking component for locking the position of the positioning reflector plate 3. The locking component includes a fastening bolt 4 threaded onto the machine body 1. The positioning reflector plate 3 has an adjustment groove 33 along its adjustment direction. The fastening bolt 4 is located in the adjustment groove 33 and is used to press against the positioning reflector plate 3.

[0031] The implementation principle of Example 1 is as follows: The worker manually moves the positioning backing plate 3 according to the size of the wire harness terminal, thereby moving the positioning slot 31 to the appropriate position. Then, the fastening bolt 4 is tightened to press it firmly onto the positioning backing plate 3. During testing, the worker manually places the wire harness terminal into the positioning slot 31. Each wire of the wire harness terminal is located on the backing plate 5. The identifier 2 identifies the color of each wire to determine if the wire sequence is accurate.

[0032] Example 2 Reference Figure 3 The difference between this embodiment and embodiment 1 is that: a guide groove 104 is provided on the body 1 along the adjustment direction of the positioning backing plate 3, and the positioning backing plate 3 extends into the guide groove 104 and slides with it.

[0033] Reference Figure 3 The machine body 1 is also provided with a lifting groove 102 parallel to the guide groove 104 and a support groove 103 perpendicular to the guide groove 104. The support groove 103 is connected to the lifting groove 102. A bottom strip 6 slides vertically in the lifting groove 102, and a support arm 7 slides vertically in the support groove 103. The support arm 7 and the bottom strip 6 are integrally formed.

[0034] Reference Figure 3 The body 1 is threadedly connected to the bottom wall of the support groove 103 with a vertical rod 10. The support arm 7 is slidably sleeved on the vertical rod 10 with a clearance fit. An elastic ball 11 is also slidably sleeved on the vertical rod 10. The elastic ball 11 supports the support arm 7 and the bottom wall of the support groove 103.

[0035] Reference Figure 3 The locking component includes a column head 8 that slides vertically through the positioning backing plate 3, and an elastic suction cup 9 that is bonded to the bottom of the oil-filled part. The elastic suction cup 9 is fastened to the body 1, and the bottom strip 6 passes through the elastic suction cup 9.

[0036] The implementation principle of Example 2 is as follows: After the worker manually adjusts the positioning backing plate 3 to a suitable position, the worker manually presses the column head 8, the elastic suction cup 9 moves downward and the air between it and the machine body 1 is squeezed out, thereby forming a negative pressure between the two, so that the elastic suction cup 9 is attached to the machine body 1, thereby locking the position of the positioning backing plate 3.

[0037] When readjustment is needed, the worker presses down on the support arm 7, which drives the bottom strip 6 to move downward. Air enters the elastic suction cup 9 from the support groove 103 and the lifting groove 102, releasing the negative pressure adsorption state, and the positioning reflector plate 3 can be moved again.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
