Description

Technical Field

[0001] The utility model relates to the technical field of circuit terminal detection equipment, in particular to a wiring terminal detection conduction jig. Background Art

[0002] As is well known, with the development of industrial modernization and automation technology, circuits are applied more and more widely. For example, the circuits of equipment such as numerical control machine tools, agricultural machinery, and automobiles are more and more numerous and complex, and their wiring terminals are also more and more. The quality of the wiring terminals is directly related to the stability of the use performance and the service life of the equipment.

[0003] A wiring terminal generally includes a terminal fixing shell, a terminal wire, a terminal plug, and a wire pressing plate. A wire pressing plate mounting hole is provided on the side of the terminal fixing shell. The terminal plug is fixedly connected to the front side of the terminal fixing shell. The terminal wire is inserted into the terminal fixing shell, and the end of the terminal wire is connected to the terminal plug. The wire pressing plate is mounted on the wire pressing plate mounting hole on the side of the terminal fixing shell. The terminal wire in the terminal fixing shell is pressed and positioned by the wire pressing plate to prevent the terminal wire from loosening and then detaching from the terminal plug, which affects subsequent use. Currently, the existing conduction jigs can only detect the circuit conduction of the wiring terminal and cannot detect the installation condition of the wire pressing plate on the side of the terminal fixing shell. After the wire pressing plate is not installed in place and warps, although the circuit of the wiring terminal is conductive, due to the warping of the wire pressing plate, the terminal wire in the terminal fixing shell loosens and then detaches from the terminal plug, reducing the service life of the subsequent terminal plug.

[0028] Furthermore, an outer guide rod 16 is connected to the wiring terminal fixing seat 31. The other end of the outer guide rod 16 is inserted into a linear guide hole of the probe fixing seat 4. An outer return spring 17 is sleeved on the outer guide rod 16, and the linear sliding between the wiring terminal fixing seat 31 and the probe fixing seat 4 is realized through the outer guide rod 16.

[0029] Furthermore, a spring post hole is provided in the middle of the guide rail 3. The spring ball hole extends into the guide rail base 2 below the guide rail 3.

The upper part of the locking spring 18 is connected to the spring post 26. A locking groove cooperating with the spring post 26 is provided at the bottom of the wiring terminal fixing seat 31. A card slot 19 for driving the spring post 26 to move up and down is provided on the side surface of the spring post 26.

[0030] Furthermore, pneumatic operation holes are provided on the guide rail base 2 and the probe fixing seat 4 on one side surface of the hole of the spring post 26. A pneumatic operation rod 20 is provided in the pneumatic operation holes. A pneumatic operation spring 21 is sleeved on the pneumatic operation rod 20. One end of the pneumatic operation rod 20 extends into the card slot 19 on the side surface of the spring post 26. The other end of the pneumatic operation rod 20 is connected to a pneumatic joint 22. The pneumatic joint 22 is fixed on the probe fixing seat 4.

[0031] Furthermore, a manual operation hole is provided on the guide rail base 2 on the other side surface of the hole of the spring post 26. A manual operation rod 23 is provided in the manual operation hole. One end of the manual operation rod 23 extends into the card slot 19 on the side surface of the spring post 26. The other end of the manual operation rod 23 extends out of the guide rail base 2.

[0032] Furthermore, the guide rail 3 is provided as a dovetail-shaped convex platform. A dovetail-shaped groove cooperating with the dovetail-shaped convex platform is provided at the lower end of the wiring terminal fixing seat 31.

[0033] Furthermore, the spring post 26 includes a cylinder body 24 and a ball head body 25. The cylinder body 24 and the ball head body 25 are fixedly connected as a whole. A card slot 19 is provided on the side surface of the cylinder body 24.

[0034] The detection base 12 described above is in a square frame shape. The detection insertion plate 13 is fixed on one side wall of the square frame-shaped detection base 12.

[0035] The wiring terminal includes a terminal fixing shell 27, a terminal wire 28, a terminal plug, and a wire pressing plate 29. A wire pressing plate mounting hole is provided on the side surface of the terminal fixing shell 27. The terminal plug is fixedly connected to the front side of the terminal fixing shell 27. The terminal wire 28 is inserted into the terminal fixing shell 27. The end of the terminal wire 28 is connected to the terminal plug. The wire pressing plate 29 is mounted on the wire pressing plate mounting hole on the side surface of the terminal fixing shell 27. The terminal wire 28 in the terminal fixing shell 27 is pressed and reset by the wire pressing plate 29.

[0036] In the above solution, since the terminal fixing shell 27 of the terminal block is inserted into the terminal block insertion slot 5, the wire pressing plate 29 on the terminal fixing shell 27 of the terminal block faces the position of the pressing plate detection slot 6 on the side of the terminal block insertion slot 5. When detection is carried out, the terminal block fixing seat 31 moves towards the probe fixing seat 4. When the wire pressing plate 29 is not properly installed and warps, the detection insertion plate 13 on the probe fixing seat 4 contacts the warped wire pressing plate 29. During the continuous movement of the terminal block fixing seat 31, the pressing plate detection sleeve 9 is subjected to a pressure towards the rear by the detection insertion plate 13, thereby driving the pressing plate detection sleeve 9 to move into the probe detection slot 7. Therefore, it can be clearly seen that the pressing plate detection sleeve 9 moves backward. At this time, it indicates that the wire pressing plate 29 is not in contact properly and needs to be reinstalled. If the wire pressing plate 29 is properly installed, then the detection insertion plate 13 bracket inserts into the bottom of the straight pressing plate detection slot 6 and will not squeeze the pressing plate detection sleeve 9, and thus the pressing plate detection sleeve 9 will not move backward. Therefore, through this device, in addition to detecting the conduction of the circuit, it can also detect the connection condition between the wire pressing plate 29 of the terminal block and the terminal fixing shell 27, whether the connection is in place. Moreover, during the movement of the terminal block fixing seat 31, both ends of the terminal fixing shell 27 of the terminal block in the terminal block insertion slot 5 of the terminal block fixing seat 31 impact the detection base 12 and the wear-resistant plate 15 in the pressing plate detection seat respectively. Since both the detection base 12 and the wear-resistant plate 15 are made of wear-resistant aluminum metal material, the wear-resistant effect can be improved. At the same time, both the detection base 12 and the wear-resistant plate 15 are detachable. When worn, the individual parts can be replaced, increasing the service life. After the terminal block fixing seat 31 and the probe fixing seat 4 are butted and the on-off of the detection circuit is checked, the spring post 26 can be separated from the terminal block fixing seat 31 by pressing the manual operating rod 23 or actuating the pneumatic operating rod 20, and the terminal block fixing seat 31 is ejected, thereby completing the detection process. Since the present utility model adopts the above structure, it has the advantages of simple structure, long service life, and the ability to detect the situation of the wire pressing plate 29 of the terminal fixing shell 27 of the terminal block, etc.
