[0002] Cable connectors are suitable for various network systems, machinery or energy or signal transmission applications. Through cable connectors, conductors (wires) can be connected to appropriate matching components to achieve the circuit connection and disconnection functions. The cable connector includes an insulating module and a core wire. The end of the core wire is connected to a pin, and the pin is embedded in the insulating module. In order to make the pin firmly embedded in the insulating module, it is usually necessary to use a pin pusher to push the pin into the insulating module; in order to detect whether the pin is stuck on the insulating module, it is necessary to use a pin detector to perform a thrust test on the pin; when the pin needs to be removed, it is necessary to use a pin remover to assist in removing the pin from the insulating module. This requires the use of a variety of disassembly and assembly tools during the disassembly and assembly process of the pin, resulting in a large number of disassembly and assembly tools and a high tool cost. Summary of the invention

[0009] Furthermore, the connecting unit is provided with a through second through groove, the second through groove includes a first groove section and a second groove section, the first groove section is provided with a second internal thread, and the connector is provided with a second external thread adapted to the second internal thread, so that the connector can be detachably connected to the first groove section; the needle tube is passed through the second groove section and extends toward the outside of the shell.

[0010] Furthermore, the disassembly and assembly unit includes a push rod, which is inserted into a first through slot of the shell, a first end of the push rod is slidably inserted into the needle tube, and a second end of the push rod passes through a second end of the shell.

[0011] Furthermore, the disassembly and assembly unit includes a spring, the spring is inserted into the push rod, a limiting portion is provided in the middle of the push rod, and the spring can be placed between the limiting portion and the second end of the shell.

[0016] The connector pin disassembly and assembly mechanism of the present invention has the following advantages over the prior art:

[0017] 1. The disassembly unit and the shell are detachably connected through a connecting unit, so that the disassembly unit can be replaced with the needle tube actually needed. For example, when it is necessary to push the needle, replace it with a disassembly unit with a needle pushing function; when it is necessary to detect whether the pin is stuck on the insulating module, replace it with a disassembly unit with a needle detection function; when it is necessary to remove the pin, replace it with a disassembly unit with a needle withdrawal function. One mechanism has multiple functions, which can save tool costs and reduce the number of tools.

[0018] 2. The same disassembly and assembly unit is used for needle detection and needle withdrawal, which can save tool costs. When the spring is placed between the limit part and the second end of the shell, the disassembly and assembly unit performs the needle detection function, the push rod rests on the pin, the push rod is pushed back, the spring is in a compressed state, and the second end of the push rod moves back so that the nut is away from the second end of the shell. The operator can read the detection force value from the scale near the second end of the push rod to know whether the pin is clamped on the insulating module. When the spring is placed between the limit part and the joint, the spring can push the limit part to rest on the step. When the needle tube is inserted into the clamping part of the pin, the nut is pushed, so that the push rod moves forward to push the pin, and the pin is removed from the insulating module to achieve the purpose of withdrawing the pin.

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0035] See attached Figures 1 to 11The connector pin disassembly and assembly mechanism of the present invention is used for disassembling and assembling cable pins, and can be used as a pin pusher, a pin detector, and a pin remover according to actual needs. The cable connector includes an insulating module 100 and a core wire 101, and the end of the core wire 101 is connected to a pin 102. The pin 102 has a wing 103 on both sides, and the free end of the wing 103 extends obliquely outward. When the pin 102 passes through the through hole on the insulating module 100 from the head, the wing 103 rests on the boss in the through hole of the insulating module 100 to prevent the pin 102 from retreating. The pin 102 is detachably embedded in the insulating module 100. The connector pin disassembly and assembly mechanism of the present invention includes: a shell 1, the shell 1 is cylindrical, and the shell 1 includes a first end 11 and a second end 12 opposite to each other. Knurling 111 is respectively provided on the outer surfaces of the first end 11 and the second end 12 to increase friction and prevent slipping during use. The shell 1 includes a first through groove 13 that passes through the first end 11 and the second end 12; a disassembly unit 2, which can act on the pin for disassembly and assembly of the pin; a connecting unit 3, which is detachably connected to the first end 11 of the shell, and the disassembly unit 2 is detachably embedded in the connecting unit 3.

[0036] In this embodiment, the connection unit 3 is a threaded structure. The inner side of the first end 11 of the housing 1 is provided with a first internal thread 14. The connection unit 3 is provided with a first external thread 31 adapted to the first internal thread 14, so that the connection unit 3 can be detachably connected to the first end 11 of the housing. The disassembly unit 2 includes a joint 21 and a needle tube 22. The needle tube 22 can directly act on the insertion pin for disassembly of the insertion pin; the joint 21 is detachably embedded in the connection unit 3. The connection unit 3 is provided with a through second through groove 32. The second through groove 32 includes a first groove section 321 and a second groove section 322. The first groove section 321 is provided with a second internal thread 323. The joint 21 is provided with a second external thread 211 adapted to connect the second internal thread 323, so that the joint 21 can be detachably connected to the first groove section; the needle tube 22 is provided in the second groove section 322 and extends toward the outside of the housing. The joint 21 includes a third through groove 212, and one end of the needle tube 22 is fixed in the third through groove 212.

[0037] The disassembly unit 2 of the present invention is detachable, so the disassembly unit 2 can be replaced according to actual needs. The number of the disassembly units 2 is at least two, and the needle tubes of the two disassembly units are different. In this embodiment, the connector pin disassembly mechanism includes three usage states, namely, a needle pusher state, a needle detector state, and a needle remover state. The disassembly unit 2 includes two, namely, a first disassembly unit 201 and a second disassembly unit 202. When the first disassembly unit 201 is installed, the connector pin disassembly mechanism is used as a needle pusher, and the needle tube 22 of the first disassembly unit 201 has a groove 221, which is convenient for placing the core wire, see Figures 1 to 4. Since the core wire is usually soft and a large number of core wires are usually arranged on an insulating module 100, in order to facilitate and better embed the plug pin on the insulating module, a pin pusher is required to push the plug pin into the insulating module. The end of the core wire 101 is connected to the plug pin 102, the core wire 101 is placed on the groove 221, the end of the needle tube 22 is against the plug pin 102, and then the needle tube 22 is inserted into the hole of the insulating module until the plug pin 102 is against the hole and the wing 103 is against the boss in the through hole of the insulating module 100, completing the pin pushing step.

[0038] When it is necessary to detect whether the pin 102 is clamped on the insulating module 100, a pin detector is required to perform a thrust test on the pin. Figures 4 to 7 The needle tube of the second disassembly and assembly unit 202 is different from the needle tube of the first disassembly and assembly unit 201. The needle tube 22 of the second disassembly and assembly unit 202 is a hollow column without a groove. In addition to the connector 21 and the needle tube 22, the second disassembly and assembly unit 202 also includes a push rod 23. The push rod 23 is inserted into the first through groove 13 of the shell 1. The first end of the push rod 23 can be slidably inserted into the needle tube 22. The second end of the push rod 23 passes through the second end 12 of the shell 1. The second end of the push rod is detachably connected to the nut 4. The push rod 23 is provided with a scale near the second end, which can be used to read the value. The disassembly and assembly unit 2 also includes a spring 24. The spring 24 is sleeved and inserted on the push rod 23. A limiting portion 231 is provided in the middle of the push rod 23. The limiting portion 231 protrudes from the push rod 23. The spring 24 can be placed between the limiting portion 231 and the second end 12 of the shell 1. Under normal conditions, the nut is pressed against the second end 12 of the housing 1 under the action of the spring 24 .

[0039] When the pin 102 needs to be removed from the insulating module 100, a pin remover is required to assist in removing the pin from the insulating module. At this time, remove the disassembly unit 2, place the spring 24 between the limit portion 231 and the connector 21, see Figure 4 , Figures 8 to 11 The first through slot 13 is provided with a step 131, and the limiting portion 231 of the push rod 23 can be stopped on the step 131. Under normal conditions, under the action of the spring 24, the nut is away from the second end 12 of the housing 1 by a certain distance.

[0040] In actual operation, when the needle pusher is needed, the first disassembly unit 201 is installed on the housing 1. Specifically, the connector 21 with the needle tube 22 fixed thereon is first screwed and connected to the first groove section 321 of the connecting unit 3, and then the connecting unit 3 is screwed and connected to the first end 11 of the housing 1, and the installation of the first disassembly unit 201 is completed, and the disassembly mechanism becomes a needle pusher. The core wire 101 is placed on the groove 221 of the needle tube 22, and the end of the needle tube 22 is pressed against the pin 102. Then, the needle tube 22 is inserted into the hole of the insulating module 100 until the pin 102 is clamped in the hole and the wing 103 is pressed against the boss in the through hole of the insulating module 100, and the pin pushing step is completed.

[0041] When the needle detector needs to be used, the first disassembly unit 201 is disassembled and replaced with the second disassembly unit 202. Specifically, the connection unit 3 is first disassembled from the first end 11 of the housing 1, and then the connector 21 of the first disassembly unit 201 is disassembled from the connection unit 3, and then the connector 21 of the second disassembly unit 202 is screwed and connected to the first slot section 321 of the connection unit 3, and then the first end of the push rod 23 is inserted into the needle tube 22, and then the spring 24 is sleeved on the push rod 23, and the push rod 23 is inserted into the first through slot 13, so that the second end of the push rod 23 passes through the second end 12 of the housing 1, and then the nut 4 is screwed on the second end of the push rod 23. At this time, the spring 24 is located between the limit portion 231 and the second end 12 of the housing 1. Under the thrust of the spring 24, the nut 4 presses against the second end 12 of the housing 1, that is, the needle detector is installed. Align the disassembly and assembly unit 2 with the pin 102 so that the needle tube 22 is placed outside the pin 102, hold the shell 1 and push it forward, the push rod 23 presses against the pin 102 and retreats relative to the needle tube 22, and the nut 4 moves away from the second end 12 of the shell 1. At this time, the operator can read the value from the scale near the second end of the push rod 23, and understand whether the pin 102 is firmly fixed on the insulating module 100 based on the value. Figure 7 It is a schematic diagram showing that the push rod 23 just abuts against the insertion pin 102 . When the housing 1 is pushed, the push rod 23 can move backward relative to the needle tube 22 , and the nut 4 also moves away from the second end 12 of the housing 1 .

[0042] When the needle remover is needed, the nut 4 is removed from the second end of the push rod 23, the connecting unit 3 is removed from the first end 11 of the housing 1, the second disassembly unit 202 is removed from the housing 1, the first end of the push rod 23 is removed from the needle tube 22, the spring 24 is placed on the other side of the stop block 231, and the first end of the push rod 23 is inserted into the needle tube 22 again. At this time, the spring 24 is pressed between the stop portion 231 and the joint 21, and the second disassembly unit 202 is reconnected to the housing 1. Under the thrust of the spring 24, the nut 4 is moved away from the second end 12 of the housing 1 for a distance, and the needle remover is installed. Align the disassembly unit 2 with the pin 102 so that the needle tube 22 is placed on the outside of the pin 102. Hold the shell 1 and push it forward until the needle tube 22 is inserted into both sides of the wing 103 of the pin 102. The wing 103 is retracted under the clamping of the needle tube 22. Then push the nut 4 to move the push rod 23 forward to push the pin to move, thereby removing the pin from the insulating module.
