Description

Technical Field

[0001] This invention relates to the field of connector technology, and in particular to a secondary unlocking connector. Background Technology

[0002] Two-stage unlocking connectors typically refer to connector designs in some electronic devices or circuit boards that require an additional step to fully unlock and remove the connector after initial connection. In existing connectors, the moment the plug and socket separate, the excessive current can easily cause arcing or breakdown, threatening the safety of personnel. Two-stage unlocking connectors prevent high-current hot-plugging and unplugging, reducing the chance of arcing or breakdown and extending the connector's lifespan. However, current two-stage unlocking connectors only add an intermediate step to the unlocking process, such as multi-stage travel, with some prompts during this intermediate travel, such as clicking sounds between components. This method lacks adequate protective measures, and if the intermediate step is ignored during unlocking, there is a safety hazard. Therefore, this invention proposes a two-stage unlocking connector that provides protection during the unlocking process, preventing operators from ignoring the intermediate unlocking step and causing safety hazards. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides protection during the unlocking process, preventing operators from overlooking intermediate unlocking steps and thus avoiding potential safety hazards.

[0004] The present invention utilizes the following solution: a secondary unlocking connector, comprising a plug and a socket. The plug includes a housing; a spring pin assembly is provided in the central region of the housing; a pin is telescopically provided in the outer circumferential region of the housing, the end of the pin having a beveled area, and the central region of the beveled area having a stepped surface; the socket includes an outer sleeve, the central region of the outer sleeve having a female pin hole, and a female pin being provided inside the female pin hole; the spring pin assembly is mated with the female pin hole and contacts the female pin; an unlocking cylinder is rotatably provided on the outer sleeve, the inner side of the unlocking cylinder having a spiral groove, a waist hole being provided on the spiral path of the spiral groove, and the spiral path being divided into two segments by the waist hole, and an end hole being provided at the end of the spiral path; the pin can mate with the waist hole and the end hole for limiting; a first pusher and a second pusher are telescopically provided on the waist hole and the end hole respectively, for pushing the pin; a pressure ring is also rotatably provided on the outer sleeve, and a pressure block is arranged on the inner side of the pressure ring for controlling the first pusher and the second pusher.

[0005] As a preferred embodiment, the outer inner region of the outer shell is provided with a pin, and the outer inner region of the outer sleeve is provided with a socket, with the pin and the socket being inserted into each other.

[0006] As a preferred embodiment, the spring needle assembly includes a syringe disposed in the central region inside the housing, a spring needle telescopically disposed on the syringe, and a spring four for providing elastic force between the spring needle and the syringe.

[0007] As a preferred embodiment, the pin has a groove on its circumference, and the pin is telescopically mounted on the outer casing through the groove. A spring is connected between the end of the pin and the outer casing to provide elastic force.

[0008] As a preferred embodiment, the socket further includes a wire clamp and a tail sleeve. The wire clamp is used to fix the cable. The end of the outer sleeve is provided with a threaded portion. The tail sleeve is installed on the outer sleeve through the threaded portion. A sealing ring is provided on the outer sleeve at the end of the threaded portion.

[0009] As a preferred embodiment, the end of the pressure ring is provided with an arc shaft, which is rotatably engaged with the outer side of the outer sleeve; a second spring is sleeved on the arc shaft to provide a restoring elastic force.

[0010] As a preferred embodiment, the first pushing component includes a push plate slidably mounted on the waist hole, and the second pushing component includes a push plate slidably mounted on the end hole. Both the first and second push plates are provided with push rods, which are pushed and controlled by pressure blocks.

[0011] As a preferred embodiment, both push plate one and push plate two are provided with push shafts, and spring three is sleeved on the push shafts to provide a reset elastic force; the push shafts are used to contact the stepped surface on the push inclined area; the pin is located on the waist hole, and the push member one can be pushed by the pressure block to make the pin pop out of the waist hole; the pin is located on the end hole, and the push member two can be pushed by the pressure block to make the pin pop out of the end hole.

[0012] The beneficial effects of this invention compared with the prior art are: (1) During the separation process, when the pin moves to the waist hole and engages with the waist hole, the spring pin first separates from the end face of the mother pin. At this time, the current is disconnected, realizing the separation of the large current; and the pin is still engaged with the socket, realizing the second unlocking; (2) During the unlocking process, the pin is engaged in the middle path. The operator cannot ignore it. Only by pushing the pin with pusher one and pusher two can the unlocking continue, which plays a protective role; (3) Pusher one and pusher two are respectively engaged in the waist hole and the end hole, which can block the waist hole and the end hole and prevent impurities and dust from causing blockage; (4) Since the end face of the pin has a beveled area, during the connection process, when the pin is engaged in the waist hole, the outer sleeve can be rotated directly without the need for pusher one and pusher two to push the pin. The beveled area can be stretched and contracted by the side of the waist hole; and during the unlocking, the pin is completely limited and cannot be unlocked directly. Attached Figure Description

The plug includes a housing 1; a spring pin assembly 6 is provided in the central region of the housing 1; a pin 7 is telescopically provided in the outer circumferential region of the housing 1, the end of the pin 7 has a beveled area 701, and the central region of the beveled area 701 has a stepped surface 702; the socket includes an outer sleeve 10, the central region of the outer sleeve 10 has a female pin hole 12, and a female pin 9 is provided inside the female pin hole 12; the spring pin assembly 6 is mated with the female pin hole 12 and contacts the female pin 9; an unlocking mechanism is rotatably provided on the outer side of the outer sleeve 10. The inner side of the cylinder 4 is provided with a spiral groove 401. The spiral path of the spiral groove 401 is provided with a waist hole 402, which divides the spiral path into two segments. The end of the spiral path is provided with an end hole 403. The pin 7 can cooperate with the waist hole 402 and the end hole 403 for limiting. Pushing member one and pushing member two are respectively telescopically provided on the waist hole 402 and the end hole 403 for pushing the pin 7. A pressure ring 13 is also rotatably provided on the outer side of the outer sleeve 10. A pressure block 16 is arranged on the inner side of the pressure ring 13 for controlling pushing member one and pushing member two.

[0028] The outer side of the inner shell 1 is provided with a pin 5, and the outer side of the inner shell 10 is provided with a socket 11. The pin 5 and the socket 11 are inserted into each other. The spring needle assembly 6 includes a syringe 603 located in the central area inside the shell 1. A spring needle 601 is telescopically provided on the syringe 603. A spring 602 for providing elastic force is provided between the spring needle 601 and the syringe 603. A groove is provided on the circumference of the pin 7. The pin 7 is telescopically provided on the shell 1 through the groove. A spring 8 for providing elastic force is connected between the end of the pin 7 and the shell 1.

[0029] The socket also includes a wire clamp 2 and a tail sleeve 3. The wire clamp 2 is used to fix the cable. A threaded part 1001 is provided at the end of the outer sleeve 10. The tail sleeve 3 is installed on the outer sleeve 10 through the threaded part 1001. A sealing ring 1002 is provided on the outer sleeve 10 and at the end of the threaded part 1001. An arc shaft 15 is provided at the end of the pressure ring 13. The arc shaft 15 is rotatably engaged with the outer side of the outer sleeve 10. A spring 14 is sleeved on the arc shaft 15 to provide a return spring force.

[0030] Pushing component one includes a push plate 404 slidably mounted on the waist hole 402, and pushing component two includes a push plate 405 slidably mounted on the end hole 403. Both push plate 404 and push plate 405 are provided with push rods 406, which are pushed and controlled by pressure block 16. Both push plate 404 and push plate 405 are provided with push shafts 408, and springs 407 are sleeved on push shafts 408 to provide reset elastic force. Push shafts 408 are used to contact the stepped surface 702 on the pushing inclined area 701. The pin 7 is located on the waist hole 402 and can be pushed by pressure block 16 to make the pin 7 pop out of the waist hole 402. The pin 7 is located on the end hole 403 and can be pushed by pressure block 16 to make the pin 7 pop out of the end hole 403.

[0031] Operating principle: When the plug and socket are connected, pin 5 mates with socket 11, spring pin assembly 6 mates with female pin hole 12, and spring pin 601 contacts female pin 9, thus connecting the current. In the connected state, pin 7 engages with end hole 403 to achieve limiting and fixing. When disassembling, first rotate pressure ring 13 to push pressure block 16 against push rod 406, causing push plate 405 to move, spring 407 to be compressed, and push shaft 408 contacts step surface 702 on inclined area 701, which can push pin 7 out of end hole 403. Then, by rotating outer sleeve 10... The pin 7 moves on the spiral groove 401, thereby separating the plug and socket. During the separation process, when the pin 7 moves to the waist hole 402 and engages with the waist hole 402, the spring pin 601 first separates from the end face of the female pin 9. At this time, the current is disconnected, realizing the separation of the large current; and the pin 5 is still engaged in the socket 11. By rotating the pressure ring 13 again, the pressure block 16 pushes the push plate 404, and the push shaft 408 contacts the stepped surface 702 on the push inclined area 701, causing the pin 7 to disengage from the waist hole 402. By rotating the outer sleeve 10, the plug and socket are unlocked.

[0032] It should be noted that during the unlocking process, the operator must ensure that the pin 7 is engaged in the middle path. Unlocking can only continue by pushing the pin 7 with pusher one and pusher two. At the same time, pusher one and pusher two are respectively installed on the waist hole 402 and the end hole 403, which can block the waist hole 402 and the end hole 403 to prevent impurities and dust from causing blockage. Furthermore, since the end face of the pin 7 has a beveled area 701, during the connection process, when the pin 7 is engaged in the waist hole 402, the outer sleeve 10 can be rotated directly without the need for pusher one and pusher two to push the pin 7. The beveled area 701 can be extended and retracted by the compression of the side of the waist hole 402. However, during unlocking, the pin 7 is completely limited and cannot be unlocked directly.

[0033] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
