[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0022] See also Figure 1-4 A highly applicable wire harness continuity test bench includes a test bench body 1, a plurality of receiving slots 11 are arranged on the upper surface of the test bench body 1, a plurality of filling modules 3 and a plurality of socket modules 2 are detachably arranged in the plurality of receiving slots 11, and the plurality of socket modules 2 and the filling modules 3 are arranged one by one corresponding to the plurality of receiving slots 11;
[0023] Specifically, the test bench body 1 is a transversely arranged quadrangular prism structure, and a plurality of receiving grooves 11 are arranged on the upper surface of the quadrangular prism test bench body 1, each receiving groove 11 is a quadrangular prism groove with a square cross section, and a plurality of quadrangular prism receiving grooves 11 are arranged on the upper surface of the test bench body 1 in a horizontal and vertical array with respect to each other, and each quadrangular prism receiving groove 11 is arranged in abutment with adjacent receiving grooves 11; at the same time, each filling module 3 and each socket module 2 are quadrangular prisms with a square cross section, and the square cross section of the quadrangular prism socket module 2 or the filling module 3 is consistent with the cross-sectional shape of the quadrangular prism receiving groove 11, at this time, whether it is the filling module 3 or the socket module 2, it can be smoothly inserted into the receiving groove 11 and fit with the inner wall of the receiving groove 11;
[0024] At the same time, the quadrangular prism-shaped filling module 3 and the quadrangular prism-shaped socket module 2 are equal in size in the axial direction, and the surface of the filling module 3 is a smooth surface, and a socket 22 is provided at the center of the top surface of the socket module 2. Specifically, at this time, when a plurality of filling modules 3 and the socket modules 2 are arranged in the receiving groove 11, a plurality of top surfaces are flush with each other to form a plane, and a plurality of sockets 22 are provided at the positions of the plurality of socket modules 2 in the plane, and each socket 22 constitutes a fixture for accommodating the wiring harness to be tested;
[0025] At the same time, the socket 22 is used to accommodate the wiring harness to be tested, and the socket module 2 is used to test the wiring harness in the socket 22. Specifically, each socket module 2 can perform high voltage, current and resistance tests on the wiring harness in the socket 22. At the same time, the test bench body 1 is provided with an insulation performance tester and a waterproof performance tester, which are used to perform insulation performance tests and waterproof performance tests on several wiring harnesses connected to several socket modules 2, respectively;
[0026] When in use, after the pre-shaped wire harness is set on the surface of the conduction test bench, the operator sets the socket module 2 at the position of several ports, and sets the filling module 3 in the remaining receiving slots 11, so that a socket 22 is formed to match the workbench plane of the end of the wire harness. The operator inserts the wire harness into the socket 22 to complete the test;
[0027] Specifically, a connection port 12 is provided at the bottom of each accommodating slot 11, and a connector 21 is provided at the bottom of each socket module 2. The connection port 12 is provided at the middle position of the square bottom surface of the accommodating slot 11, and the connector 21 is provided at the middle position of the square bottom surface of the socket module 2. At this time, when the socket module 2 is provided in the accommodating slot 11, the connector 21 is inserted into the connection port 12, and the socket module 2 and the test bench body 1 are electrically connected to each other through the connector 21 and the connection port 12. At this time, when the wiring harness is inserted into the socket 22 of the socket module 2, it can be electrically connected to the test bench body 1.
[0028] During the above process, the conductivity test bench needs to perform conductivity tests on wiring harnesses of different pre-shaped shapes. The end positions of wiring harnesses of different pre-shaped shapes are different. At this time, the position of the socket 22 needs to be changed. At this time, the operator pulls out the socket 22 from the current receiving slot 11, and at the same time pulls out the filling module 3 at the corresponding position of the new wiring harness end to free up space in the receiving slot 11, and then inserts the socket module 2 into the position that matches the end of the new wiring harness, and puts the filling module 3 in the remaining vacant receiving slots 11 to complete the adaptation of the conductivity test bench to different wiring harnesses.
[0029] In the above process, after the socket module 2 is placed in the receiving groove 11, there is a probability that it cannot be completely placed in the receiving groove 11. At this time, the connector 21 at the bottom of the socket module 2 cannot be tightly connected with the connector 12, and the connection between the socket module 2 and the test bench body 1 is not tight. In order to remind the operator whether the socket module 2 is installed in place in the receiving groove 11, a first contact 13 is provided at the bottom of any receiving groove 11, and a second contact 23 is provided at the bottom of any socket module 2. The first contact 13 and the second contact 23 are arranged in coordination. The first contact 13 and the second contact 23 contact each other after the socket module 2 is arranged in the receiving groove 11, and the second contact 23 is connected to the first contact 13 after contacting each other. A prompt circuit and an alarm light are provided in any socket module 2, and the prompt circuit, the alarm light and the second contact 23 are connected in series with each other;
[0030] Specifically, each socket module 2 is provided with a prompt circuit structure, which includes a power supply connected in series, a second contact 23 and an alarm light, the second contact 23 is two contacts set separately from each other, and the two ends of the prompt circuit are respectively connected to the two contacts of the second contact 23. At this time, the entire prompt circuit structure is in a disconnected state in a natural state due to the provision of the second contact 23, and only after the two contacts of the second contact 23 are connected to each other, the entire prompt circuit is energized, and the alarm light lights up under the drive of the power supply;
[0031] At the same time, for the first contact 13, the first contact 13 includes two metal contacts arranged at the bottom of the receiving groove 11, and the two contacts of the first contact 13 are connected in series with each other. The setting position of the first contact 13 ensures that when the socket module 2 is correctly placed in the receiving groove 11, the two contacts of the second contact 23 and the two contacts of the first contact 13 are in contact with each other.
[0032] When the socket module 2 is correctly set, the second contact 23 abuts against the first contact 13, and the two first contacts 13 connected to each other connect the two ends of the second contact 23 that are disconnected, indicating that the circuit is connected, and the alarm light is on. After the operator observes the alarm light that is on, it can be known that the socket module 2 is correctly set in the receiving slot 11. On the contrary, when the setting position of the socket module 2 deviates, resulting in the first contact 13 not abutting against the second contact 23, since the second contact 23 cannot be connected, it indicates that the circuit is disconnected, and the alarm light is off. At this time, the operator can judge that the socket module 2 is not accurately set by observing that the alarm light is not on;
[0033] By setting the first contact 13 and the second contact 23 so as to contact each other only after being correctly set, and at the same time setting the alarm light and the second contact 23 in series with each other in the prompt circuit, the alarm light is only lit when it is correctly installed, that is, the second contact 23 is in contact with the first contact 13, so that the operator can judge whether the socket module 2 is installed in place by observing the lighting of the alarm light of each socket module 2.
[0034] To prevent the socket module 2 or the filling module 3 from falling out after being locked, any accommodating slot 11 is provided with a locking buckle, which is used to lock or unlock the filling module 3 or the socket module 2 in the accommodating slot 11. Specifically, the locking buckle is a protrusion protruding from the side wall of the accommodating slot 11, and the protrusion is made of flexible material. At the same time, the socket module 2 or the filling module 3 is provided with a depression on the side wall to cooperate with the protrusion. When the operator puts the socket module 2 into the accommodating slot 11, the protrusion and the depression cooperate with each other to prevent the socket module 2 or the filling module 3 from moving in its own axial direction, thereby completing the locking.
[0035] The working principle and use process of this utility model:
[0036] When in use, after the pre-shaped wire harness is set on the surface of the conduction test bench, the operator sets the socket module 2 at the position of several ports, and sets the filling module 3 in the remaining receiving slots 11, so that a socket 22 is formed to match the workbench plane of the end of the wire harness. The operator inserts the wire harness into the socket 22 to complete the test;
[0037] When it is necessary to test wire harnesses with different pre-shaped shapes, the end positions of wire harnesses with different pre-shaped shapes are different. At this time, it is necessary to change the position of the socket 22. At this time, the operator pulls out the socket 22 from the current receiving slot 11, and at the same time pulls out the filling module 3 at the corresponding position of the new wire harness end to free up space in the receiving slot 11, and then inserts the socket module 2 into the position that matches the end of the new wire harness, and puts the filling module 3 in the remaining vacant receiving slot 11 to complete the applicability of the conduction test bench to different wire harnesses.
