Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically to a cable testing fixture anti-misinsertion guide device. Background Technology

[0002] In the 3C industry, cables are frequently tested using cable testing fixtures to assess their quality and compliance with requirements. A cable consists of connector terminals and the cable body connected to those terminals. During testing, the connector terminals are inserted into a test board within the cable testing fixture, allowing the test board to measure relevant cable parameters.

[0003] A known Chinese patent (application number 202420782131.9) discloses a cable testing fixture, which includes a test plate and a support frame. The test plate is provided with a mating interface, and connector terminals are used to be inserted into the mating interface in a set direction. The support frame includes a support column, a connecting seat, and a limiting seat. The support column extends in a set direction, and the connecting seat and the limiting seat are spaced apart in a set direction. The support column is connected between the connecting seat and the limiting seat. The connecting seat is connected to the test plate. The limiting seat is provided with a limiting groove, and the limiting groove extends through the limiting seat in a set direction. The limiting groove is used to pass through the cable body. When testing the cable, the cable body passes through the limiting groove. The groove wall of the limiting groove can assist in limiting the cable body, so as to prevent the part of the cable body between the connecting seat and the limiting seat from tilting under its own weight, thereby reducing the impact on the connector terminals and ensuring that the connector terminals and the mating interface do not become loose.

[0004] However, in implementing the relevant technology, the above-mentioned cable testing fixture has the following problems: Existing technology makes it difficult to detect mis-insertion during testing. Consequently, even if the cable has serious defects such as short circuits, open circuits, or poor insulation, the mis-insertion test may detect an incorrect path, leading to a "qualified" report for a defective cable. If this cable enters the market and is installed in equipment, it will cause end-product malfunctions, resulting in huge after-sales costs and brand reputation losses. Therefore, a mis-insertion prevention guide device for cable testing fixtures is proposed. Utility Model Content

[0005] This invention proposes an anti-misinsertion guide device for cable testing fixtures, solving the problem that existing technologies struggle to detect misinsertion during testing. Consequently, even if a cable has serious internal defects such as short circuits, open circuits, or poor insulation, the misinsertion test may detect an incorrect path, leading to a "qualified" report for a faulty cable. This cable, once on the market and installed in equipment, can cause end-product malfunctions, resulting in significant after-sales costs and damage to brand reputation.

[0006] The technical solution of this utility model is as follows: A cable testing fixture anti-misinsertion guide device, comprising:

[0007] Test box and controller;

[0008] The mounting plate is fixedly installed on the inner bottom wall of the test chamber, and the top of the mounting plate is provided with a test plate, and the top of the test plate is provided with multiple test interfaces.

[0009] A voice module is located on one side of the inner wall of the test chamber;

[0010] A vision module is installed on the inner top wall of the test chamber, and the controller is electrically connected to the voice module and the vision module respectively.

[0011] Preferably, the baffle is slidably connected to one side of the top of the test chamber via an opening groove;

[0012] A groove is formed on the top of the baffle.

[0013] Preferably, two mounting slots are formed opposite to each other on both sides of the baffle;

[0014] The spring is fixedly installed inside the two mounting slots.

[0015] Preferably, the limiting pin is fixedly installed at one end of the spring;

[0016] Two limiting holes are provided on opposite sides of the test box, and the limiting pin is inserted into the two limiting holes.

[0017] Preferably, the handle is fixedly installed on the top of the test box;

[0018] An anti-slip sleeve is fitted onto the outer wall of the handle.

[0019] Preferably, four anti-slip pads are disposed at the bottom of the test chamber, and the four anti-slip pads are distributed at the four corners of the bottom of the test chamber.

[0020] The working principle and beneficial effects of this utility model are as follows:

[0021] Before testing the cables, a vision module collects data on the cables to be tested and performs connection tests on different cables and test interfaces. After data collection, the testing begins. Staff insert the cables into the test interfaces, and the vision module detects the cables during insertion. If a cable is detected as not being connected to the correct test interface, the information is transmitted to the controller. The controller then activates the voice module, which issues a voice announcement to alert the staff to the incorrect connection and prompt timely adjustments. This achieves the goal of preventing incorrect connection detection and effectively prevents the transmission of incorrect connection information to staff, thus avoiding the problem of substandard cables entering the market.

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0030] Please see Figure 1 - Figure 5A cable testing fixture with a mis-insertion prevention guide device, comprising:

[0031] Test box 1 and controller;

[0032] Mounting plate 2 is fixedly installed on the inner bottom wall of test chamber 1. Test plate 3 is provided on the top of mounting plate 2. Multiple test interfaces 4 are provided on the top of test plate 3.

[0033] Voice module 5 is located on one side of the inner wall of test chamber 1;

[0034] The vision module 6 is located on the inner top wall of the test chamber 1, and the controller is electrically connected to the voice module 5 and the vision module 6 respectively.

[0035] The technical solution provided by this utility model is as follows: Before testing the cable, the vision module 6 collects data on the cable to be tested and performs connection tests on different cables and test interfaces 4. After the data collection is completed, the cable testing begins. The operator inserts the cable to be tested into the test interface 4 for testing. During the insertion process, the vision module 6 detects the cable. If the cable is detected as not corresponding to the test interface 4, the information is transmitted to the controller. The controller then activates the voice module 5, which issues a voice broadcast to remind the operator of the incorrect insertion into the test interface 4, allowing for timely adjustment of the operation. This achieves the purpose of preventing incorrect insertion detection of the cable and effectively prevents the transmission of incorrect insertion detection information to the operator, thus preventing unqualified cables from entering the market.

[0036] Furthermore, the baffle 7 is slidably connected to one side of the top of the test chamber 1 via a groove, the groove 8 is formed on the top of the baffle 7, two mounting slots 9 are formed opposite to each other on both sides of the baffle 7, the spring 10 is fixedly installed inside the two mounting slots 9, the limiting pin 11 is fixedly installed at one end of the spring 10, and two limiting holes 12 are formed opposite to each other on both sides of the test chamber 1, with the limiting pin 11 and the two limiting holes 12 interlocking.

[0037] Specifically, by pressing the limiting pin 11, the spring 10 retracts, and the limiting pin 11 disengages from the limiting hole 12. At the same time, the limiting pin 11 enters the mounting groove 9. Then, by pressing down the baffle 7, the baffle 7 moves downward. When the limiting pin 11 and the limiting holes 12 on both sides of the test box 1 are on the same horizontal line, the spring 10 pushes the limiting pin 11 outward under the action of elastic restoring force, so that the limiting pin 11 automatically inserts into the corresponding position of the limiting hole 12 for limiting and fixing. Thus, the test plate 3 is in a closed state, which prevents dust from entering the test plate 3 when it is not in use.

[0038] Furthermore, the handle 13 is fixedly installed on the top of the test box 1, and the anti-slip sleeve 14 is fitted onto the outer wall of the handle 13.

[0039] Specifically, the handle 13 on the test box 1 makes it easy to lift the test box 1, and the anti-slip sleeve 14 on the handle 13 prevents the test box 1 from slipping accidentally when lifting it.

[0040] Furthermore, four anti-slip pads 15 are set at the bottom of the test chamber 1, and the four anti-slip pads 15 are distributed at the four corners of the bottom of the test chamber 1.

[0041] Specifically, the anti-slip pad 15 is used to increase the friction between the test box 1 and the table, so that the test box 1 is placed stably on the table and prevents accidental slippage.

[0042] The working principle of this utility model is as follows: Before testing the cable, the vision module 6 collects data on the cable to be tested and performs connection tests on different cables and test interfaces 4. After the data collection is completed, the cable testing begins. The operator inserts the cable to be tested into the test interface 4. During the insertion process, the vision module 6 detects the cable. If the cable is not detected to be in the corresponding test interface 4, the information is transmitted to the controller. The controller then activates the voice module 5, which issues a voice broadcast to remind the operator of the incorrect insertion into the test interface 4, allowing for timely adjustment of the operation. This achieves the purpose of preventing incorrect insertion of cables and effectively prevents the transmission of incorrect insertion detection information to the operator, thus preventing unqualified cables from entering the market.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
