[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0032] Please refer to Figures 1-7 , the present utility model provides the following technical solutions:

[0033] Embodiment 1: In order to facilitate the limit treatment of the connector housing, reference can be made to the attached Figure 1 - attached Figure 4 , the limit mechanism includes a bidirectional threaded rod 4 rotatably connected to one side of the movable load-carrying plate 3. The outer side of the bidirectional threaded rod 4 is threadedly connected to one side of the limit block 5, and the other side of the limit block 5 is slidably disposed inside the movable load-carrying plate 3. The inner side of the limit block 5 is a conductor. The outer side of the air blowing head 10 corresponds to one side of the conductor. The inner sides of the two limit blocks 5 are attached to the outer side of the connector housing. One end of the elastic airbag 7 connected to the air delivery pipe 9 is provided with a one-way air outlet valve, and a one-way air inlet valve is provided on the outer side of the elastic airbag 7.

[0034] During the detection, first place the connector housing on the top of the movable load-carrying plate 3. At this time, by rotating the bidirectional threaded rod 4 rotatably provided on one side of the movable load-carrying plate 3, the limit block 5 threadedly connected to the outer side of the bidirectional threaded rod 4 will move on the top of the movable load-carrying plate 3. At this time, the connector housing is limited by the two relatively moving limit blocks 5.

[0035] Embodiment 2: Different from Embodiment 1, in order to solve the problem that when the connector detection device on the current market tightly limits the connector, a certain amount of dust is likely to remain on the surface of the connector housing, and there may be a problem of poor contact when connecting and conducting electricity to the connector, reference can be made to the attached Figure 1 - attachedFigure 5 , including a base 1, on one side at the top of the base 1, an electric push rod 2 is fixedly installed; further comprising: the output end of the electric push rod 2 is fixed on one side of the movable loading plate 3, a limiting mechanism is arranged on the top of the movable loading plate 3, and the limiting mechanism cooperates with the arranged cleaning mechanism to act on the conductive position of the connector for cleaning; the cleaning mechanism includes a guide block 6 fixedly arranged at the bottom of the limiting block 5, an elastic air bag 7 is fixed on one side of the guide block 6, a baffle 8 is fixed at the bottom position of the movable loading plate 3, the outer side of the elastic air bag 7 is connected to the head end position of an air delivery pipe 9, and the tail end of the air delivery pipe 9 is connected to one side of the limiting block 5 and communicated with a blowing head 10; on one side of the base 1 away from the movable loading plate 3, a group of fixing plates 14 are fixed, and a plurality of fixing plates 14 are rotatably arranged on the fixing plates 14. When the two groups of limiting blocks 5 move relatively, the guide block 6 fixed at the bottom of the limiting block 5 will move, so that the elastic air bag 7 fixed on one side of the guide block 6 will approach and contact one side of the baffle 8. In addition, when the elastic air bag 7 continues to move, through the cooperative arrangement of the baffle 8, the gas inside the elastic air bag 7 will be conveyed through the air delivery pipe 9. At this time, the gas can jet the blowing head 10 through the air delivery pipe 9, so that the gas jetted by the blowing head 10 will clean the position where the limiting block 5 contacts the connector, and the dust can be effectively cleaned, thus avoiding the phenomenon of poor contact.

[0036] Embodiment 3: In order to facilitate the conductivity detection of the pin 20, reference can be made to the attached Figure 1 - attached Figure 7 , on one side of the movable loading plate 3, a plurality of sockets 11 are arranged, and indicator lights 12 are arranged on the outer side of the middle of the sockets 11. On the bottom position of the movable loading plate 3, a group of docking rods 13 are arranged. The number of the docking rods 13, the number of the sockets 11 and the number of the pins 20 are set to be the same, and one side of the socket 11 is connected to a wire assembly 21 arranged inside the movable loading plate 3 through a conductor. A plurality of groups of receiving tubes 15 are opened at the lower position of the fixing plate 14. A piston block 16 is slidably arranged inside the receiving tube 15. The rear end position of the piston block 16 is fixed inside the fixing plate 14 and connected to a connecting air pipe 17. A connecting rack 18 is slidably arranged at the top position of the connecting air pipe 17. The outer side of the connecting rack 18 is meshed and connected to the inner side of a rotating gear 19. The outer side position of the rotating gear 19 is rotatably arranged inside the fixing plate 14, and a pin 20 is inserted into the center position of the rotating gear 19. A piston is fixed at the bottom position of the connecting rack 18, and the outer side of the piston is attached to the inner wall position of the connecting air pipe 17. The outer side of the fixing plate 14 corresponds to one side position of the docking rod 13. In addition, the piston block 16 is connected to one side of the receiving tube 15 through a spring.

[0037] In addition, when performing the detection work on the pin 11, first insert the pin 20 into the interior of the wire assembly 21 through the hole of the wire assembly 21, and embed the outer side of the pin 20 into the hole of the rotating gear 19. Subsequently, by moving the electric push rod 2, the output end of the electric push rod 2 will also drive the moving carrier plate 3 to move on the top of the base 1, so that one end of the socket 11 and the indicator light 12 will move towards the side of the fixed plate 14, and one end of the socket 11 will be docked to the outer side of the pin 20. At this time, the insertion process can be completed. In addition, during the movement of the moving carrier plate 3, one end of the docking rod 13 will fit against one side of the piston block 16, causing the piston block 16 to slide inside the receiving tube 15, so that the gas inside the receiving tube 15 will be transported through the connecting air tube 17. At this time, the piston provided inside the connecting air tube 17 will drive the connecting rack 18 to move, so that when the connecting rack 18 moves upward, the outer side of the connecting rack 18 will drive the meshing-connected rotating gear 19 to rotate, and the outer side position of the rotating gear 19 will drive the pin 20 to rotate inside the socket 11, avoiding the phenomenon of oxidation on the surface of the pin 20, which may cause poor contact. And the current forms a closed loop through the external power supply, the moving carrier plate 3, the indicator light 12, the docking rod 13, the wire assembly 21 and the pin 20. If all the indicator lights 12 are on, it proves that all the pins 20 are qualified. If any indicator light 12 is not on, it proves that the pins 20 in that part are unqualified.
