Description

Technical Field

[0001] The present invention relates to a puller, in particular to a puller for a high voltage electrical connector. Background Art

[0002] Electrical connectors are required when large equipment is connected to each other. For underground instruments, such as geological exploration instruments and underground drilling instruments, since their use environment is underground, high-voltage electrical connectors need to have the characteristics of pressure resistance, mud resistance, and anti-fouling. In order to make the electrical connector more pressure-resistant and anti-fouling, the high-voltage electrical connector needs at least two layers of sealing rings and outer shells to protect its inner core. Since there are at least two layers of sealing rings, the high-voltage electrical connector and its outer shell are tightly fitted to each other and are not easy to separate from each other. When the staff is conducting equipment inspection and equipment repair, the outer shell and inner core of the electrical connector need to be separated from each other. Because the sealing ring is clamped, the staff needs specific tools to separate the inner core and the outer shell of the high-voltage electrical connector.

[0003] Based on this background, the present invention provides a puller for separating an inner core and an outer shell of a high voltage electrical connector. Summary of the invention

DETAILED DESCRIPTION

[0022] A puller for an electrical connector described in the present invention is characterized in that it includes: a main frame 1, a three-claw hook 2, a needle 3, a limit pin 5, a spring 6, a needle handle 7, a handle 8, a rotating rod 9, a handle shaft 10, a press spring 11, a pin A12, a limit block 13, a spiral pin 14, a pin B15, and a hexagon socket screw 16, wherein the main frame 1 carries all the components of the puller, the handle 8 is fixed at one end of the rotating rod 9, the three-claw hook 2 can be locked with the lock 20 of the electrical connector, the needle handle 7 is located at one end of the needle 3, and when the needle handle 7 is pressed to insert the needle 3 into the pin hole 18 of the electrical connector, the positioning pin 19 of the electrical connector and the outer shell 21 of the electrical connector are no longer clamped, so that the electrical connector is separated from its outer shell 21.

[0023] The hexagon socket screw 16 is rotatably fixed on the rotating rod 9, and the hexagon socket screw 16 can fix the position of the push spring 11. The hexagon socket screw 16 can be rotated to move it in a direction perpendicular to the rotating rod 9. One end of the push spring 11 is located between the hexagon socket screw 16 and the rotating rod 9. The push spring can be loosened or fixed by adjusting the rotation of the hexagon socket screw 16. In practical applications, in order to facilitate screwing, the inventor selects the hexagon socket screw 16 with a diameter of 5 mm and a thread length of 18 mm without the nut as the optimal size of the hexagon socket screw 16.

[0024] The limit block 13 is fixedly connected to the rotating rod 9. The function of the limit block 13 is to allow the limit pin 5 to enter the hole of the main frame 1. When the limit pin 5 enters the hole of the main frame, the relative position of the rotating rod 9 and the main frame 1 is fixed.

[0025] The push spring 11 is fixedly connected to the limit pin 5 . Pressing the push spring 11 will cause displacement between the limit pin 5 and the limit block 13 , and then the limit pin 5 enters the hole located in the main frame 1 .

[0026] The spring 6 can drive the rotating rod 9 to rotate.

[0027] The spiral pin 14 can fix the position of the needle 3 and prevent the needle 3 from rotating.

[0028] The pin A12 is located on the rotating rod 9, and the pin A12 can fix the rotating rod 9 and the limit block 13 to prevent relative displacement. The pin B15 can limit the rotation range of the three-claw hook 2, so that the three-claw hook 2 can align with the lock 20 of the electrical connector.

[0029] The puller is provided with a marking groove 17 on its periphery. When the puller is inserted into the electrical connector housing 21 , the marking groove 17 is aligned with the housing marking groove 23 on the electrical connector housing, so that the puller can be smoothly pushed into the housing 21 .

[0030] In some embodiments, a threaded ring 4 is disposed on the periphery of the puller, and the threaded ring 4 is adapted to the housing thread 22 on the housing 21 of the electrical connector.

[0031] The puller of the electrical connector with the above structure has the characteristics of simple structure and can easily realize the pulling out and pushing back of the inner core of the electrical connector.

[0032] Since the puller has threads on its periphery, the puller can be rotated into or out of the housing of the electrical connector, making it easier to push the electrical connector into and out of the housing.

[0033] The use process of the puller of the electrical connector described in the present invention is as follows:

[0034] When pulling, align the marking groove 17 of the puller with the shell marking groove 23 on the shell of the electrical connector to ensure that the shell 21 and the puller can be smoothly docked. In some embodiments, the threaded ring 4 on the outer periphery of the puller can be used to screw the puller into the shell 21. In an embodiment where the puller does not have a threaded ring 4, the puller can be directly pushed into the shell 21. Push the needle 3 of the puller into the pinhole 18 of the shell 21 to achieve the fixation between the electrical connector and the puller. Subsequently, push the handle 8 in the direction of the electrical connector and rotate the handle 8 clockwise to achieve the locking between the three-claw hook 2 and the lock 20, and further fix the electrical connection and the puller. At this time, the handle 8 of the puller can be pulled out to pull the electrical connector. In some embodiments, the puller has a threaded ring 4 on the outer periphery. At this time, the electrical connector can be rotated and screwed out of the shell 21. In an embodiment where the puller does not have a threaded ring 4, the puller can be directly pulled out of the shell 21. The electrical connector is separated from the shell 21 along with the puller. At this time, the electrical connector is removed, and the spring 6 drives the rotating rod 9 to rotate counterclockwise and reset.

[0035] When pushing, dock the electrical connector and the puller, insert the needle 3 of the puller into the pinhole 18 of the electrical connector, rotate the handle 8 clockwise to lock the lock 20 of the electrical connector, align the marking groove 17 of the puller with the shell marking groove 23 on the shell of the electrical connector, and send the electrical connector plug into the shell. In the embodiment with the threaded ring 4, the puller can be screwed into the shell 21 by using the threaded ring 4, and in the embodiment where the puller does not have the threaded ring 4, the puller can be directly pushed into the shell 21. Then, press the spring 11, rotate the handle 8 counterclockwise to release the lock between the three-claw hook 2 and the lock 20, pull the needle handle 7 to pull the needle 3 out of the pinhole 18, and rotate the threaded ring 4 to separate the puller and the shell.
