Description

Technical Field

[0001] This utility model relates to an electrical connector, and more particularly to an electrical connector that is easy to assemble and disassemble quickly and reliably. Background Technology

[0002] Electrical connectors are used in electromechanical equipment to achieve rapid electrical connection and disconnection. They generally consist of plugs and sockets that are connected by interlocking contacts (pins or sockets). Electrical connectors should have characteristics such as good contact, reliable operation, and easy maintenance. In the circuits of critical equipment such as aerospace equipment, electrical connectors must have even more reliable connection stability, meaning that the plug and socket should not be separated due to external forces during use.

[0003] To ensure a more reliable connection between the plug and socket of an electrical connector, and to facilitate assembly and disassembly, a locking structure is often installed between the plug and socket. The traditional locking structure is usually a locking ring, which is fitted onto the housing of the plug or socket and prevented from detaching by a convex ring. The locking ring is connected to the external thread on the housing of the socket or plug through an internal thread, thereby achieving the locking function between the plug and socket.

[0004] The traditional locking structure of the aforementioned electrical connector has the following drawbacks: locking and unlocking operations require manual rotation of the locking ring, making assembly and disassembly cumbersome. Furthermore, for high-performance electrical connectors, an anti-rotation structure must be installed between the housing and the locking ring, further complicating the structure. Utility Model Content

[0005] The purpose of this invention is to provide an electrical connector that is easy to assemble and disassemble quickly and reliably in order to solve the above problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] An electrical connector for quick and reliable assembly and disassembly includes a plug and a socket. The plug includes a plug housing and plug contacts, with multiple plug contacts mounted within the plug housing via a plug insulator. The socket includes a socket housing and socket contacts, with multiple socket contacts mounted within the socket housing via a socket insulator. Each plug contact is individually plugged into a corresponding socket contact. A first end of the plug housing is positioned within the socket housing cavity near the first end. The socket further includes a first annular clamping ring, a second annular clamping ring, a second annular clamping ring, a third annular "V"-shaped toothed ring, a fourth annular unlocking ring, and a sealing ring. The first and second clamping rings are mounted within the socket housing cavity, with the first clamping ring positioned near the first end. The plug, the "V"-shaped toothed ring includes a support ring and multiple toothed pieces. The multiple toothed pieces are connected to the same end of the support ring and are evenly distributed in the circumferential direction. Each toothed piece and the support ring form a "V" shape in the radial direction of the support ring. The support ring of the "V"-shaped toothed ring is installed between the first clamping ring and the second clamping ring and is fixedly clamped. One end of the unlocking ring is placed in the first clamping ring and contacts the multiple toothed pieces. The unlocking ring is axially movable. The sealing ring is installed at the bottom of the inner cavity of the socket housing. An annular groove is provided on the outer circumferential wall of the plug housing near the first end. The first end of the plug housing passes through the central through hole of the unlocking ring and is in close contact with the sealing ring. The suspended ends of the multiple toothed pieces are placed in the annular groove.

[0008] Preferably, in order to facilitate reliable fixation of the clamping support ring and leave room for the toothed plate to move during unlocking, and to prevent the unlocking ring from disengaging from the first clamping ring to abut against the toothed plate and keep the electrical connector locked, the inner wall of the first clamping ring is thinned twice from the end near the unlocking ring to the end near the second clamping ring to form a first annular "L"-shaped step and a second annular "L"-shaped step, respectively. The second clamping ring has an annular boss at the end near the first clamping ring, and the central through hole of the annular boss is a conical hole, and the diameter of the conical hole at the end near the first clamping ring is larger than the diameter at the other end. The support ring of the "V"-shaped toothed ring is installed between the second "L"-shaped step and the annular boss. The outer circumference of the unlocking ring near the toothed plate has an unlocking ring boss, and the unlocking ring boss is located inside the first "L"-shaped step.

[0009] Preferably, in order to facilitate the direct insertion of the unlocking ring into the first clamping ring for quick assembly, the outer circumferential wall surface of the unlocking ring boss is a conical surface, and the diameter of one end of the conical surface near the tooth is smaller than the diameter of the other end. The ring wall of the unlocking ring is provided with a plurality of opening slots evenly distributed along the circumferential direction, and the opening slots are open at one end near the tooth.

[0010] Preferably, to facilitate the unlocking operation, the unlocking ring has an operating protrusion that protrudes outward in the peripheral direction at the end away from the toothed plate.

[0011] Preferably, in order to facilitate the reliable installation of the first clamping ring, the second clamping ring, and the sealing ring inside the socket housing cavity, the first clamping ring is threadedly connected to the circumferential cavity wall of the socket housing cavity, and the second clamping ring is pressed against the bottom of the socket housing cavity. The sealing ring is located inside the second clamping ring and is attached to the bottom of the socket housing cavity.

[0012] Preferably, in order to facilitate the rapid disengagement of the toothed plate from the annular groove during the unlocking operation, the groove wall surface near the opening end on the side of the annular groove closest to the sealing ring is a conical surface, and the diameter of the opening end of the conical surface is larger than the diameter of the other end.

[0013] Preferably, in order to improve the overall strength of the "V" shaped toothed ring, the plurality of toothed pieces are integrally formed with the support ring.

[0014] Preferably, in order to facilitate the installation of the plug on electrical equipment, the middle section of the outer circumferential wall of the plug housing is provided with a mounting protrusion protruding in the outward direction, and the mounting protrusion is provided with a mounting hole.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention involves installing a first clamping ring, a second clamping ring, a "V"-shaped toothed ring, an unlocking ring, and a sealing ring on the socket, and setting an annular groove on the plug housing. When connecting the plug and socket, simply insert the plug housing directly into the socket housing. When the teeth of the "V"-shaped toothed ring enter the annular groove, mechanical locking and positioning between the plug and socket is achieved. To unlock, simply push the socket and plug closer together to compress the sealing ring, creating a gap between the suspended end of the toothed ring and the groove wall near the sealing ring in the annular groove. Then, push the unlocking ring to squeeze the toothed ring, causing the suspended end of the toothed ring to bend and disengage from the annular groove, thus completing the unlocking function. The plug and socket can then be directly separated. The entire assembly and disassembly process (connecting and separating the plug and socket) is simple and efficient, especially convenient when connecting the plug and socket. Moreover, the locking is firm and reliable, eliminating the need for an anti-rotation structure in threaded locking. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1-3 As shown, the electrical connector of this utility model, which facilitates quick and reliable assembly and disassembly, includes a plug and a socket. The plug includes a plug housing 10 and plug contacts 13. Multiple plug contacts 13 are installed inside the plug housing 10 via plug insulators 11. The socket includes a socket housing 27 and socket contacts 29. Multiple socket contacts 29 are installed inside the socket housing 17 via socket insulators 28. Multiple plug contacts 13 are respectively plugged into multiple socket contacts 29 in a one-to-one correspondence (the figure shows the pins of plug contacts 13 inserted into the socket holes of socket contacts 29). The first end of the plug housing 10 is placed in the socket housing cavity (not marked in the figure) of the socket housing 27 near the first end of the two ends. The socket also includes a first annular clamping ring 22, a second annular clamping ring 25, a second annular clamping ring 24, a third annular "V" shaped toothed ring 24, a fourth annular unlocking ring 21, and a sealing ring 26. The first clamping ring 22 and the second clamping ring 25... 5. The first clamping ring 22 is installed in the inner cavity of the socket housing and is close to the plug. The "V"-shaped toothed ring 24 includes a support ring (not marked separately in the figure) and multiple toothed pieces (not marked separately in the figure). The multiple toothed pieces are connected to the same end of the support ring and are evenly distributed in the circumferential direction. Each toothed piece and the support ring form a "V" shape in the radial direction of the support ring. The support ring of the "V"-shaped toothed ring 24 is installed between the first clamping ring 22 and the second clamping ring 25 and is fixedly clamped. One end of the unlocking ring 21 is placed in the first clamping ring 22 and contacts the multiple toothed pieces. The unlocking ring 21 can move axially. The sealing ring 26 is installed at the bottom of the inner cavity of the socket housing. The plug housing 10 has an annular groove 14 on the outer circumferential wall near the first end. The first end of the plug housing 10 passes through the central through hole of the unlocking ring 21 and is in close contact with the sealing ring 26. The suspended ends of the multiple toothed pieces are placed in the annular groove 14.

[0022] like Figures 1-3 As shown, this utility model also discloses the following more optimized specific structures:

[0023] To facilitate reliable fixation of the support ring and provide space for the toothed plate to move during unlocking, and to prevent the unlocking ring 21 from disengaging from the first clamping ring 22 to hold the toothed plate in place and keep the electrical connector locked, the inner wall of the first clamping ring 22 is thinned twice from the end near the unlocking ring 21 to the end near the second clamping ring 25 to form a first annular "L"-shaped step (not marked separately in the figure) and a second annular "L"-shaped step (not marked separately in the figure). The second clamping ring 25 has an annular boss (not marked separately in the figure) at the end near the first clamping ring 22, and the central through hole of the annular boss is a conical hole, and the diameter of the conical hole at the end near the first clamping ring 22 is larger than the diameter at the other end. The support ring of the "V"-shaped toothed ring 24 is installed between the second "L"-shaped step and the annular boss. The outer circumference of the unlocking ring 21 near the toothed plate has an unlocking ring boss 23, and the unlocking ring boss 23 is located inside the first "L"-shaped step.

[0024] To facilitate quick assembly by directly inserting the unlocking ring 21 into the first clamping ring 22, the outer circumferential surface of the unlocking ring boss 23 is a conical surface, and the diameter of the end of the conical surface near the tooth is smaller than the diameter of the other end. The ring wall of the unlocking ring 21 is provided with a plurality of opening slots evenly distributed along the circumferential direction (not visible in the figure, but easy to understand; the opening slots are used to make the ring wall of the unlocking ring 21 elastic, so that the unlocking ring boss 23 can be pushed into the first clamping ring 22), and the opening slot is open at the end near the tooth.

[0025] To facilitate the unlocking operation, the unlocking ring 21 has an operation protrusion 20 that protrudes outward in the peripheral direction at the end away from the toothed piece.

[0026] To facilitate the reliable installation of the first clamping ring 22, the second clamping ring 25, and the sealing ring 26 within the inner cavity of the socket housing, the first clamping ring 22 is threadedly connected to the circumferential cavity wall of the inner cavity of the socket housing, and the second clamping ring 25 is pressed tightly against the bottom of the inner cavity of the socket housing. The sealing ring 26 is located inside the second clamping ring 25 and is attached to the bottom of the inner cavity of the socket housing.

[0027] In order to facilitate the quick disengagement of the toothed plate from the annular groove 14 during the unlocking operation, the groove wall surface near the opening end on the side of the annular groove 14 close to the sealing ring 26 is a conical surface (not marked in the figure), and the diameter of the opening end of the conical surface is larger than the diameter of the other end.

[0028] To improve the overall strength of the "V"-shaped toothed ring 24, multiple toothed pieces are integrally formed with the support ring.

[0029] To facilitate the installation of the plug on electrical equipment, the middle section of the outer circumference of the plug housing 10 is provided with a mounting protrusion 12 that protrudes outward in the circumferential direction, and the mounting protrusion 12 is provided with a mounting hole (not visible in the figure).

[0030] like Figures 1-3 As shown, in use, the plug is installed on the electrical equipment via the mounting ring 12, and connected to the corresponding pin on the electrical equipment through the socket at the end of the plug contact 13 away from the socket. The solder cup at the end of the socket contact 29 away from the plug is soldered to the wire. When the socket and plug need to be connected, the socket contact 29 is aligned with the plug contact 13, and the unlocking ring 21 is aligned with the first end of the plug housing 10 and inserted. During the insertion process, the unlocking ring 21 first aligns with and is inserted into the first end of the plug housing 10, and then multiple socket contacts 29 and multiple plug contacts 13 contact and align with each other and are inserted. When the suspended ends of multiple teeth contact the first end of the plug housing 10, the teeth will bend and deform under their own elasticity, without affecting the continued movement of the socket towards the plug. The sealing ring 26 is pressed against the first end of the plug housing 10. Subsequently, the suspended ends of multiple toothed plates begin to enter the annular groove 14. Under the elastic action of the toothed plates themselves, the suspended ends of the toothed plates reset and contact the bottom of the annular groove 14. At this time, a contact sound will be emitted, indicating that the socket and plug are connected in place. At this time, the electrical connection and mechanical locking between the socket and plug are completed. If the socket is subjected to an external force away from the plug during use, the suspended ends of the toothed plates will tend to push the corresponding groove wall of the annular groove 14. At the same time, the toothed plates will be subjected to a reverse force to push the locking ring 21. However, because the middle section of the toothed plates is abutted by the corresponding end of the locking ring 21 and the locking ring 21 cannot move away from the toothed plates due to the locking ring boss 23, the socket and plug cannot move away from each other and cannot be separated, thus maintaining the locked state and avoiding accidents caused by electrical disconnection.

[0031] When it is necessary to connect the socket and the plug, first push the socket towards the plug to forcefully compress the sealing ring 26, so that there is a certain gap between the suspended ends of the multiple teeth and the groove wall of the annular groove 14 near the sealing ring 26. Then push the unlocking ring 21 away from the plug. The unlocking ring 21 squeezes the teeth, causing the suspended ends of the teeth to bend and detach from the annular groove 14. Then the plug and the socket can be directly separated.

[0032] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
