Description

Technical Field

[0001] The utility model relates to a multi-segment connector pin and belongs to the technical field of connectors. Background Art

[0002] A connector is also called a connector, and is also called a joint and socket in China. It generally refers to an electrical connector, that is, a device that connects two active devices to transmit current or signals. The male and female ends can transmit information or current after contact, and are also called connectors.

[0003] The interface of the connector needs to be installed with pins, and is connected to other components through the pins to achieve current transmission. In order to improve the conductive effect of the pin, a metal with good conductive effect is plated on the surface of the pin. However, the pin will produce a certain amount of wear each time it is plugged in and out during the plugging work. After long-term use, the metal on the surface may cause a decrease in conductivity due to wear. At this time, the entire pin needs to be replaced. However, when the pin is plugged in, only part of the position is in the plugged state, and most of the position is still inside the connector. The unplugged part is still intact. When the pin needs to be replaced, if the unworn part is replaced at the same time, it will cause waste of materials and increase the replacement cost.

[0004] To this end, a multi-segment connector pin is proposed. Utility Model Content

[0005] In view of this, the utility model provides a multi-segment connector pin to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0006] The technical solution of the utility model is implemented as follows: a multi-segment connector pin, comprising a main pin and a secondary pin, a threaded rod is fixedly installed at the bottom of the secondary pin, and insertion holes are opened around the surface of the threaded rod;

[0007] The inner cavity of the main needle is provided with a disassembly mechanism, and the disassembly mechanism includes a disc, which is arranged in the inner cavity of the main needle, and adjustment grooves are opened around the top of the disc, and connecting rods are movably connected in the inner cavities of the four adjustment grooves, and mounting frames are fixedly installed at the bottoms of the four connecting rods, and movable plates are fixedly installed at the bottoms of the four mounting frames, and plug rods are fixedly installed on the tops of the four movable plates. Hard springs are fixedly installed on the outer sides of the four movable plates, and a pull rod is fixedly installed on the top of the disc.

[0008] Further preferably, a movable groove is opened in the inner cavity of the main needle, and the disc is movably connected to the inner cavity of the movable groove.

[0009] Further preferably, movable grooves are provided around the bottom of the inner cavity of the main needle, and the bottoms of the four hard springs are slidably connected to the inner cavities of the four movable grooves through sliders.

[0010] Further preferably, slots are provided around the inner side of the main needle inner cavity, and the four insertion rods pass through the inner cavities of the four slots and are inserted into the inner cavities of the four insertion holes.

[0011] Further preferably, the four slots and the four jacks are in the same horizontal direction, and the four slots and the jacks are connected to each other.

[0012] Further preferably, a displacement groove is provided at the top of the main needle, and the pull rod passes through the inner cavity of the displacement groove and extends to the top of the main needle.

[0013] Further preferably, conductive sheets are fixedly mounted on the bottom of the threaded rod and the bottom of the inner side of the main needle, and the two conductive sheets are in contact with each other.

[0014] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0015] 1. The utility model can separately disassemble and replace the secondary needle by setting a disassembly mechanism. When the pull rod is pulled to move, the disc rotates, and the position of the adjusting groove is changed at this time, and the connecting rod is pushed outward to move. With the movement of the connecting rod, the mounting frame drives the moving plate and the insertion rod to move outward synchronously, so that the insertion rod is moved out of the inner cavity of the insertion hole. At this time, the hard spring is deformed due to the squeezing of the moving plate, and then the secondary needle is rotated to make the threaded rod move out from the inner side of the main needle, completing the disassembly of the secondary needle. Then, the new secondary needle is threadedly connected to the inner side of the main needle through the threaded rod, and then the pull rod is released. At this time, due to the disappearance of the force, the hard spring is deformed again. The movable plate is deformed and pushed inward by its own tension, and the movable plate drives the plug rod, the mounting frame and the connecting rod to move inward again. With the movement of the connecting rod, the disc rotates and drives the pull rod to move to the left. At this time, the plug rod is plugged into the inner cavity of the socket again to fix the secondary pin, thereby realizing the replacement of the worn part of the pin, avoiding the need to completely replace the entire pin due to the poor conductive effect after the surface coating of the pin is worn out due to repeated plugging and unplugging, so that the unworn area of ​​the pin also needs to be replaced, thereby saving material waste, reducing the cost of repairing and replacing the pin, and facilitating people's use.

[0016] Second, the utility model can provide a movable groove to support the disc and limit its position when it rotates, so as to avoid the position changing during rotation, which in turn affects the fixing or removal of the secondary needle by the insertion rod. By providing a movable groove, the moving direction of the hard spring can be limited, so as to avoid the disc rotating, due to the change of the position of the adjusting groove, which causes the position of the connecting rod to change synchronously, thereby causing the insertion rod to be unable to be inserted into the inner cavity of the jack, affecting the replacement of the secondary needle. By providing a slot, the moving direction of the insertion rod can be limited. To prevent the insertion rod from offsetting when it moves, thereby affecting the removal or installation effect of the secondary needle, by setting the slots and the holes, because they are in the same horizontal direction and are interconnected, the insertion rod will not be hindered by other components in its moving direction when it moves inward or outward, which will then lead to the problem that the insertion rod cannot remove or install the secondary needle. By setting the displacement groove, the moving direction of the pull rod can be limited to prevent the pull rod from offsetting when it moves, thereby affecting the rotation effect of the disc. By setting the conductive sheet, the conductivity of the secondary needle to the current can be improved when the main needle is connected to the secondary needle.

As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0026] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-5 As shown, the embodiment of the utility model provides a multi-segment connector pin, including a main pin 1 and a secondary pin 3, a threaded rod 4 is fixedly installed at the bottom of the secondary pin 3, and insertion holes 5 are opened around the surface of the threaded rod 4;

[0029] The inner cavity of the main needle 1 is provided with a disassembly mechanism 2, and the disassembly mechanism 2 includes a disc 201, which is arranged in the inner cavity of the main needle 1, and adjustment grooves 202 are opened around the top of the disc 201, and connecting rods 203 are movably connected in the inner cavities of the four adjustment grooves 202, and mounting frames 204 are fixedly installed at the bottom of the four connecting rods 203, and moving plates 205 are fixedly installed at the bottom of the four mounting frames 204, and insert rods 206 are fixedly installed on the top of the four moving plates 205. Hard springs 207 are fixedly installed on the outer sides of the four moving plates 205, and a pull rod 208 is fixedly installed on the top of the disc 201.

[0030] By setting up the disassembly mechanism 2, the secondary needle 3 can be disassembled and replaced separately. When the pull rod 208 is pulled to move, the disc 201 rotates. At this time, the position of the adjusting groove 202 changes, and the connecting rod 203 is pushed outward to move. As the connecting rod 203 moves, the mounting frame 204 drives the moving plate 205 and the insertion rod 206 to move outward synchronously, so that the insertion rod 206 is moved out of the inner cavity of the insertion hole 5. At this time, the hard spring 207 is deformed due to the squeezing of the moving plate 205, and then the secondary needle 3 is rotated to make the threaded rod 4 move out from the inner side of the main needle 1, completing the disassembly of the secondary needle 3, and then the new secondary needle 3 is threadedly connected to the inner side of the main needle 1 through the threaded rod 4, and then the pull rod 208 is released. At this time, due to the disappearance of the force, the hard spring 207 is deformed again, and through its own tension, it pushes the movable plate 205 to move inward, and at the same time, the movable plate 205 drives the insertion rod 206, the mounting frame 204 and the connecting rod 203 to move inward again. With the movement of the connecting rod 203, the disc 201 rotates and drives the pull rod 208 to move to the left. At this time, the insertion rod 206 is plugged into the inner cavity of the socket 5 again to complete the fixation of the secondary needle 3, so as to realize the replacement of the worn part of the pin, and avoid the need to completely replace the entire pin due to the deterioration of the conductive effect after the surface coating of the pin is worn out due to repeated plugging and unplugging, so that the unworn area of ​​the pin also needs to be replaced, which saves material waste, reduces the cost of repairing and replacing the pin, and is convenient for people to use.

[0031] Example 2

[0032] In one embodiment, a movable groove 211 is opened in the inner cavity of the main needle 1, and the disc 201 is movably connected in the inner cavity of the movable groove 211. Mobile grooves 209 are opened around the bottom of the inner cavity of the main needle 1, and the bottoms of the four hard springs 207 are slidably connected in the inner cavity of the four movable grooves 209 through sliders. Slots 210 are opened around the inner side of the inner cavity of the main needle 1, and four insertion rods 206 pass through the inner cavity of the four slots 210 and are inserted into the inner cavity of the four sockets 5. The four slots 210 and the four sockets 5 are in the same horizontal direction, and the four slots 210 and the sockets 5 are connected to each other. A displacement groove 212 is opened at the top of the main needle 1, and the pull rod 208 passes through the inner cavity of the displacement groove 212 and extends to the top of the main needle 1. The bottom of the threaded rod 4 and the bottom of the inner side of the main needle 1 are fixedly installed with conductive sheets 6, and the two conductive sheets 6 fit each other.

[0033] By setting the movable groove 211, the disc 201 can be supported and its position can be limited when it rotates, so as to avoid the position changing during rotation, thereby affecting the fixing or removal of the secondary needle 3 by the insertion rod 206. By setting the movable groove 209, the moving direction of the hard spring 207 can be limited, so as to avoid the position of the connecting rod 203 changing synchronously due to the change of the position of the adjusting groove 202 when the disc 201 rotates, thereby causing the insertion rod 206 to be unable to be inserted into the inner cavity of the jack 5, affecting the replacement of the secondary needle 3. By setting the slot 210, the moving direction of the insertion rod 206 can be limited. , to avoid the insertion rod 206 from being offset when moving, thereby affecting the removal or installation effect of the secondary needle 3. By setting the slot 210 and the hole 5, since they are in the same horizontal direction and are interconnected, the insertion rod 206 will not be hindered by other components in its moving direction when moving inward or outward, which will then cause the insertion rod 206 to be unable to remove or install the secondary needle 3. By setting the displacement groove 212, the moving direction of the pull rod 208 can be limited to avoid the pull rod 208 from being offset when moving, thereby affecting the rotation effect of the disk 201. By setting the conductive sheet 6, the conductivity of the secondary needle 3 to current when the main needle 1 is connected to the secondary needle 3 can be improved.

[0034] When the utility model is working: when the secondary needle 3 is worn out due to repeated plugging and unplugging, so that the conductive effect becomes worse, the pull rod 208 is pulled to move, and the disk 201 rotates, and the position of the adjusting slot 202 is changed. At this time, the adjusting slot 202 pushes the connecting rod 203 outward to move, and with the movement of the connecting rod 203, the mounting frame 204 drives the moving plate 205 and the insertion rod 206 to move outward synchronously, and the hard spring 207 is deformed due to the squeezing force generated when the moving plate 205 moves. At this time, the insertion rod 206 moves from the inner cavity of the socket 5, and then the secondary needle 3 is rotated to move it out from the inner side of the main needle 1, completing the disassembly of the secondary needle 3, and then replacing it. Replace the new secondary needle 3 and connect it to the inner side of the main needle 1 again through the threaded rod 4, then release the pull rod 208, at this time the hard spring 207 is deformed again due to the disappearance of the force, and pushes the movable plate 205 to move inward by its own tension, at this time the insertion rod 206, the mounting frame 204 and the connecting rod 203 move inward synchronously, the insertion rod 206 is again plugged into the inner cavity of the socket 5 to complete the fixation of the secondary needle 3, and the disc 201 is also moved in the inner cavity of the adjusting groove 202 due to the connecting rod 203, pushing the disc 201 to rotate, at this time the pull rod 208 moves in a circle to the left due to the rotation of the disc 201, and returns to the initial position, completing the replacement of the secondary needle 3 as a whole.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
