Description

Technical Field

[0001] This invention belongs to the field of connector technology, specifically relating to a multi-signal on / off switching connector and connector assembly. Background Technology

[0002] Signal conversion connectors generally refer to connectors that short-circuit between designated contacts inside a single socket. When a matching plug is inserted, the short-circuit relationship changes, thereby controlling whether the signal is "on" or "off". They are often used during transportation and storage to ensure the safety of the ignition circuit or to transmit signals during ignition.

[0003] Currently, the signal conversion area of ​​signal conversion connectors is a single-layer structure, typically only controlling the on / off function of specific signals. For example, some contacts in a single socket may be interconnected or connected in pairs, but these contacts disconnect when the plug is inserted. Therefore, existing signal conversion connectors can only achieve simple "on" or "off" switching between signals, and cannot meet users' requirements for switching specific signal conduction or disconnection relationships. The layer board and contact arrangement of the signal conversion area need to be designed according to the signal definition.

[0004] In summary, a connector needs to be developed that can convert the conduction and disconnection relationships between multiple signals as required. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a multi-signal on / off switching connector and connector assembly.

[0006] The objective of this invention is achieved through the following technical solution. A multi-signal on / off switching connector according to this invention includes a socket housing, a socket insulator disposed within the socket housing, a plurality of pin components disposed on the socket insulator, and a conductive component slidably disposed within the socket housing along the mating direction at the front end of the socket insulator. The conductive component includes a plurality of short-circuit plates stacked along the mating direction, with the projections of the holes distributed on each short-circuit plate overlapping on the connector mating end face so that the pin components can be mated with the corresponding holes. Each short-circuit plate includes a short-circuit insulator and a plurality of conductive sheets nested on the short-circuit insulator. The holes on the short-circuit plate include conductive holes disposed on the conductive sheets and insulating holes disposed on the short-circuit insulator. At least two conductive holes are provided on the same conductive sheet, and the conductive holes on the same short-circuit plate form a conductive hole array. The projections of the conductive hole arrays of at least two short-circuit plates on the connector mating end face are not completely overlapping, and the conductive sheets of adjacent short-circuit plates are insulated. The front end of the pin component is a mating end capable of mating and making conductive contact with the conductive holes on different short-circuit plates.

[0007] Compared with the prior art, the advantages of the present invention are: The conductive component slides within the socket housing. When it slides to different positions, the short-circuit board conductive sockets at different positions engage with the pin components to achieve the switching requirements of certain specific signal conduction or disconnection. This solves the technical problem that existing connectors can only achieve independent signal conduction and disconnection, and cannot achieve the switching of specified contact conduction or disconnection relationships.

[0008] Furthermore, an intermediate insulator is provided between adjacent short-circuit boards, and the sockets on the intermediate insulator are all insulated sockets. The projections of the insulated sockets on the intermediate insulator and the sockets on the short-circuit boards on the connector mating end face coincide.

[0009] Compared with the prior art, the advantages of the present invention are: Insulation between conductive plates on adjacent short-circuit boards is achieved through an intermediate insulator, ensuring normal signal conversion and transmission.

[0010] Furthermore, the conductive component also includes a fixing frame, a short-circuit plate and an intermediate insulator nested and fixed inside the fixing frame, a fixing sleeve inside the socket housing, and a sliding hole on the fixing frame that is slidably fitted onto the fixing sleeve.

[0011] Compared with the prior art, the advantages of the present invention are: By sliding the conductive component with the fixed sleeve, the conductive component is prevented from deflecting during sliding.

[0012] Furthermore, there is an insertion hole between the outer wall of the front end of the fixing sleeve and the inner wall of the front end of the socket housing for insertion with the plug. The outer wall of the front end of the fixing sleeve is provided with an anti-rotation groove extending in the insertion direction, and the anti-rotation groove slides in cooperation with the anti-rotation platform on the adapter plug.

[0013] Compared with the prior art, the advantages of the present invention are: The plug is inserted through a mating hole, and the anti-rotation slot and anti-rotation platform work together to prevent the plug from rotating during the insertion process.

[0014] Furthermore, a sealing ring I is nested on the inner wall of the front end of the socket housing for sliding sealing with the plug.

[0015] Compared with the prior art, the advantages of the present invention are: The sealing ring I ensures a seal between the plug and socket when the head is inserted.

[0016] Furthermore, the front end face of the fixed frame is nested with a sealing ring III for sealing and engaging with the inner wall of the front end of the socket housing, and the inner wall of the sliding hole is nested with a sealing ring II for sliding and sealing engagement with the fixed sleeve.

[0017] Compared with the prior art, the advantages of the present invention are: The sealing rings III and II are used to seal the socket mating end, and the mating of the plug and socket is achieved by the cooperation of the sealing ring II and the sealing ring I.

[0018] Furthermore, a locking mechanism is provided inside the fixing sleeve for locking with the plug.

[0019] Compared with the prior art, the advantages of the present invention are: The locking mechanism secures the head and base together after insertion, preventing unstable signal transmission caused by changes in the position of the head and base.

[0020] Furthermore, a positioning pin is provided on the short-circuit plate that is attached to the bottom wall of the fixed frame. When the short-circuit plate and the intermediate insulator are stacked, the positioning pin passes through the positioning hole on the short-circuit plate and the intermediate insulator to achieve accurate positioning.

[0021] Compared with the prior art, the advantages of the present invention are: By using the positioning pins and positioning holes, the short-circuit board and intermediate insulator are stacked in the correct orientation to achieve correct signal switching.

[0022] Furthermore, the conductive component is provided with two short-circuit plates: a bottom short-circuit plate and an upper short-circuit plate. The bottom short-circuit plate includes a bottom plate insulator and a bottom plate conductive sheet disposed within the bottom plate insulator. The upper short-circuit plate includes an upper plate insulator and an upper plate conductive sheet disposed within the upper plate insulator. Both the bottom plate insulator and the upper plate insulator are short-circuit insulators, and both the bottom plate conductive sheet and the upper plate conductive sheet are conductive sheets. An intermediate insulator is disposed between the bottom short-circuit plate and the upper short-circuit plate.

[0023] Furthermore, the conductive sheet is in the shape of a stepped column, the bottom plate insulator is provided with a bottom plate stepped hole that matches the bottom plate conductive sheet, and the upper plate insulator is provided with an upper plate stepped hole that matches the upper plate conductive sheet. The side with the larger diameter of the bottom plate stepped hole and the upper plate stepped hole both face the middle insulator.

[0024] Compared with the prior art, the advantages of the present invention are: Before stacking the short-circuit boards, the conductive sheets are inserted into the corresponding insulators. Then, during stacking, the conductive sheets are stopped by the intermediate insulators. The assembly is simple and the fixing is firm.

[0025] Furthermore, the insertion pin component is a component with a split insertion end and an elastic expansion hole.

[0026] Compared with the prior art, the advantages of the present invention are: The mating end is divided into several spring pieces, giving it elasticity. When not mated, the spring pieces expand outwards. When mated, under the action of the mating force, the spring pieces elastically contract and, under their own restoring force, can fit tightly against the inner wall of the socket, achieving stable signal transmission.

[0027] Furthermore, the middle part of the pin component is an insulating part used to insulate it from the conductive socket.

[0028] Compared with the prior art, the advantages of the present invention are: The insulating part insulates the pin assembly from the conductive sockets of other shorting boards, ensuring that the pin assembly only engages with and conducts with the conductive socket on one of the shorting boards.

[0029] Furthermore, an elastic element I is provided between the conductive component and the socket insulator to reset the conductive component when the headstock is separated.

[0030] Compared with the prior art, the advantages of the present invention are: After the head and seat separate via elastic element I, the conductive components reset to their original positions, thereby enabling signal switching.

[0031] Furthermore, the conductive component is provided with a guide pin for slidingly engaging with a guide pin hole on the socket insulator to guide the sliding of the conductive component.

[0032] Compared with the prior art, the advantages of the present invention are: When the pin assembly slides into the socket, the guide pin slides into the guide pin hole on the socket insulator to guide the sliding between the pin assembly and the socket, thus preventing the pin assembly from deflecting when sliding into the socket due to the elasticity of the mating end.

[0033] A connector assembly includes a socket and a plug that are mutually compatible and mating. The plug includes a plug housing, and the socket is the aforementioned multi-signal on / off conversion connector. When the head and socket are mated, the plug housing slides into the mating hole at the front end of the socket and can push the conductive parts.

[0034] Compared with the prior art, the advantages of the present invention are: This invention provides a connector assembly that, through the insertion and disconnection of a plug and socket, enables the conversion between on / off states of multiple signal pairs. The socket of this connector assembly is designed with conductive components, including multiple layers of shorting boards. During the insertion and disconnection process, the conductive components move under the push of the plug. During this process, the conductive pieces that contact the conductive components with the pins inside the socket change. Through the arrangement of the conductive pieces on the shorting boards and the multi-layer shorting board configuration, the conversion between on / off states of certain specific signals is achieved, solving the technical problem that existing connectors can only achieve independent signal on / off states and cannot achieve the conversion between on / off states of specified contacts.

[0035] Furthermore, a locking screw is rotatably mounted on the plug housing, and a locking hole is provided on the locking mechanism for cooperating with the locking screw. A locking pin is provided on one of the inner wall of the locking hole and the outer wall of the locking screw, and a locking groove is provided on the other for sliding cooperation with the locking pin. A retaining groove is provided at the rear end of the locking groove for engaging the locking pin.

[0036] Compared with the prior art, the advantages of the present invention are: Rotate the locking screw to ensure a stable connection between the plug housing and the socket.

[0037] Furthermore, a handle is provided at the rear end of the locking screw, and an elastic element II is sleeved on the locking screw between the handle and the outer wall of the plug housing. The locking screw is provided with a step that can abut against the inner wall of the plug housing under the elastic force of the elastic element II.

[0038] Compared with the prior art, the advantages of the present invention are: The elastic force of elastic element II itself can keep the locking pin in the slot, preventing loosening caused by vibration.

[0039] Furthermore, a sealing ring IV is provided between the plug housing and the locking screw to achieve rotational sealing between the plug housing and the locking screw.

[0040] Compared with the prior art, the advantages of the present invention are: The sealing ring IV achieves a seal between the plug housing and the locking screw, which, in conjunction with the sealing structure on the socket, achieves a complete seal for the connector assembly.

[0041] The above description is merely an overview of the technical solution of the present invention.

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] An embodiment of a connector assembly according to the present invention, such as... Figures 1 to 15 As shown, the connector assembly includes a socket and a plug. The socket is as follows... Figures 1 to 4 As shown, the socket includes a socket housing 1, a socket insulator 2, a pin assembly 3, an elastic element 4, a conductive component 5, a retaining sleeve 6, and a locking mechanism 7. The key structure of the socket is the conductive component 5. The plug is as follows... Figures 11 to 13 As shown, the plug includes a plug housing 8, a handle 9, and a locking screw 10. Both the plug and socket are described with the plug-in and socket-connected ends as the front end.

[0046] Conductive component 5 includes an upper plate insulator 54, an intermediate insulator 53, a bottom plate insulator 52, a conductive sheet, a fixing frame 51, and a guide pin 57, such as Figure 5 As shown. The upper plate insulator 54, the intermediate insulator 53, the bottom plate insulator 52, and the conductive sheets on the upper plate insulator 54 and the bottom plate insulator 52 constitute an insulating component. Conductive sheets 515 are provided on both the upper plate insulator 54 and the bottom plate insulator 52. The upper plate insulator 54, the bottom plate insulator 52, and their corresponding conductive sheets 515 respectively form short-circuit plates 513. The two short-circuit plates 513 are separated by the intermediate insulator 53 to prevent the conductive sheets 515 on different short-circuit plates 513 from contacting and conducting, thereby achieving insulation between the conductive sheets 515 of the short-circuit plates 513. The insulating component is nested in the fixing frame 51, and the opening of the fixing frame 51 faces the rear end. Each layer of short-circuit plates 513 and the intermediate insulator 53 in the insulating component can be sequentially put into the fixing frame 51 through the opening of the fixing frame 51. The bottom plate insulator 52 is put into the fixing frame 51 first and fits against the bottom wall of the fixing frame 51. The upper plate insulator 54 and the lower plate insulator 52 are used to nest conductive sheets 515, so that the upper plate insulator 54 and the lower plate insulator 52 both serve as short-circuit insulators 514 to insulate and fix the conductive sheets 515. A sliding hole 59 is provided at the center of the fixing frame 51, and a cavity for nesting the insulator component is provided around the sliding hole 59 in the fixing frame 51. After the insulator component is nested in the cavity, it is fixed at the cavity opening of the fixing frame 51 by riveting and closing. In other embodiments, a retaining ring can also be nested on the inner wall of the cavity opening to stop and fix the insulator component, or the insulator component can be fixed in the fixing frame 51 by force. The cavity opening of the fixing frame 51 faces the rear end, and the lower plate insulator 52, the middle insulator 53, and the upper plate insulator 54 are sequentially stacked in the cavity.

[0047] The insulator component has several sockets 58 distributed on it. These sockets 58 penetrate the upper plate insulator 54, the intermediate insulator 53, the bottom plate insulator 52, or the conductive sheet on the corresponding insulator, allowing the pin component 3 on the socket insulator 2 to pass through the entire insulator component. Specifically, the projections of the sockets 58 on the short-circuit plate 513 and the intermediate insulator 53 on the connector mating end face coincide. The sockets 58 on the short-circuit plate 513 are divided into insulating sockets 581 and conductive sockets 582. The insulating sockets 581 are located on the short-circuit insulator 514, and the conductive sockets 582 are located on the conductive sheet 515. All sockets 58 on the intermediate insulator 53 are conductive sockets 582. In this embodiment, the sockets 58 on the insulator component are distributed on six concentric circles on the insulator component. Metal conductive sheets 515 are installed in both the upper plate insulator 54 and the bottom plate insulator 52. The conductive sheets 515 installed on the upper plate insulator 54 are upper plate conductive sheets 56, and the upper plate insulator 54 and its corresponding upper plate conductive sheets 56 form an upper plate short-circuit plate 524. The conductive sheets 515 installed on the bottom plate insulator 52 are bottom plate conductive sheets 55, and the bottom plate insulator 52 and its corresponding bottom plate conductive sheets 55 form a bottom plate short-circuit plate 523. The conductive sheets 515 are arranged in specific hole positions on the two short-circuit insulators 514, and the conductive sheets 515 are nested within the corresponding short-circuit insulators 514.

[0048] In this embodiment, the arrangement of the conductive sheets 55 on the base plate is as follows: Figure 6 As shown, in the direction from the inside out, the insertion holes 58 distributed on the second concentric circle and the adjacent insertion holes 58 on the third concentric circle are disposed on the same base plate conductive sheet 55, and the two adjacent insertion holes 58 on the fifth concentric circle are disposed on the same base plate conductive sheet 55. In this embodiment, the arrangement of the upper plate conductive sheet 56 is as follows: Figure 7As shown, in the direction from the inside out, the sockets 58 distributed on the first concentric circle and the adjacent sockets 58 on the second concentric circle are disposed on the same upper plate conductive sheet 56; the sockets 58 distributed on the third concentric circle and the adjacent sockets 58 on the fourth concentric circle are disposed on the same upper plate conductive sheet 56; and the sockets 58 distributed on the fifth concentric circle and the adjacent sockets 58 on the sixth concentric circle are disposed on the same upper plate conductive sheet 56. The interconnecting holes on the two shorting plates are different. When the pin component 3 is connected to the holes on different shorting plates, the mutual conversion of the on / off relationship between multiple sets of signals (two sets of signals in this embodiment) can be realized, that is, converting one set of signals being on and the other set being off to one set of signals being off and the other set being on. In other embodiments, the arrangement of the sockets 58 and conductive pieces 515 on the corresponding shorting boards 513 can be changed as needed, as long as the projections of the conductive pieces 515 on the mating end faces of the two shorting boards 513 do not completely overlap, and thus the projections of the conductive sockets 58 on the mating end faces of the two shorting boards 513 do not completely overlap, thereby realizing the mutual conversion of the conduction and disconnection relationships between multiple sets of signals.

[0049] In this embodiment, the conductive sheet 515 is a stepped columnar body, such as... Figure 12 , Figure 13 The figures shown are two stepped conductive sheets Ⅰ518 and Ⅱ519 with different structural dimensions, representing conductive sheet 515. Stepped conductive sheet Ⅰ518 has a stop Ⅰ521 at one end, protruding from the side wall of the main body of stepped conductive sheet Ⅰ518. The length of stop Ⅰ521 is equal to the length of the main body of stepped conductive sheet Ⅰ518, but the width of stop Ⅰ521 is greater than the width of the main body of stepped conductive sheet Ⅰ518. Stepped conductive sheet Ⅱ519 has a stop Ⅱ522 at one end, protruding from the side wall of the main body of stepped conductive sheet Ⅱ519. The length of stop Ⅱ522 is equal to the length of the main body of stepped conductive sheet Ⅱ519, and the width of stop Ⅱ522 is greater than the width of the main body of stepped conductive sheet Ⅱ519. Select conductive sheet 515 of different sizes according to the location of conductive sheet 515. When the product has a limit on the diameter, for conductive sheet 515 whose length direction is parallel to the radial direction, stepped conductive sheet I 518 can be selected to reduce the space occupied in the radial direction.

[0050] The base plate insulator 52 has a stepped hole 516 that matches the base plate conductive piece 55 and is used to install the base plate conductive piece 55. The upper plate insulator 54 has a stepped hole 517 that matches the upper plate conductive piece 56 and is used to install the upper plate conductive piece 56. The larger diameter side of the stepped hole 516 and the upper plate stepped hole 517 faces the intermediate insulator 53. The base plate conductive piece 55 is inserted into the base plate insulator 52 from the side closest to the intermediate insulator 53 and is confined within the base plate insulator 52. The upper plate conductive piece 56 is inserted into the upper plate insulator 54 from the side closest to the intermediate insulator 53 and is confined within the upper plate insulator 54. Then, the base plate insulator 52, the intermediate insulator 53, and the upper plate insulator 54 are stacked, while the conductive piece 515 is confined to the corresponding short-circuit insulator. The conductive piece 515 has an oblong cross-section, leaving enough space to provide two insertion holes 58 on the conductive piece.

[0051] The shape of the conductive sheet 515 is not limited to the shape described in this embodiment, and the position of the conductive socket 582 on the shorting plate 513 is not limited to the orientation described in this embodiment. All conductive sockets 582 on the same shorting plate 513 form a conductive socket array. As long as the projections of the conductive socket arrays on the two shorting plates 513 on the mating end face are not completely overlapping (including both completely non-overlapping and partially overlapping), the signal switching is completed when the conductive component 5 slides.

[0052] Four guide pins 57 are also installed on the conductive component 5. In this embodiment, the guide pins 57 are circumferentially distributed on the upper plate insulator 54 and extend rearward from the fixing frame 51, facilitating the sliding of the conductive component 5 in the socket along the insertion direction. In other embodiments, the guide pins 57 can be provided on the bottom plate insulator 52. When the bottom plate insulator 52, the intermediate insulator 53, and the upper plate insulator 54 are stacked, the guide pins 57 pass through the positioning holes on the intermediate insulator 53 and the upper plate insulator 54, thereby ensuring accurate positioning of the bottom plate insulator 52, the intermediate insulator 53, and the upper plate insulator 54, with a portion of the guide pins 57 serving as positioning pins 520. Of course, in this embodiment, a separate positioning pin 520 can be provided on the bottom plate insulator 53, with the positioning pin 520 passing through the positioning holes on the intermediate insulator 53 and the upper plate insulator 54, achieving accurate positioning of the bottom plate insulator 52, the intermediate insulator 53, and the upper plate insulator 54.

[0053] A socket insulator 2 is fixedly installed at the rear end inside the socket housing 1. A pin component 3 is assembled in the hole of the socket insulator 2. In this embodiment, the pin component adopts a flexible expansion hole component with a mating end 31. See Figure 9 , Figure 10The front end of the pin component 3 is a mating end 31 for conductive contact. The mating end 31 is divided into several spring pieces, giving it elasticity. When not mated, the spring pieces of the mating end 31 expand outwards. When mated, under the action of the mating force, the spring pieces of the mating end 31 elastically contract, and under the action of its own restoring force, it can tightly fit with the inner wall of the socket, achieving stable signal transmission. The middle part of the pin component 3 is an insulating part 32. When the mating end 31 is mated and connected to the conductive socket 582 on the corresponding shorting board, the insulating part 32 prevents the pin component 3 from contacting and connecting with the conductive socket 582 on other shorting boards. In this embodiment, the insulating part 32 can be an insulating layer provided in the middle part of the pin component 3. The rear end of the pin component 3 is a wiring terminal, which passes through the socket insulator 2 and is used to connect to the wire on the back of the socket. The pin components 3 on the socket insulator 2 correspond one-to-one with the socket holes 58 on the insulator components, allowing the pin components 3 to be inserted into the socket holes 58. When the mating end 31 on the pin component 3 mates with the socket hole 58 on one of the conductive plates on the short-circuit board, the pin component 3 makes contact and conduction with the corresponding conductive plate, thereby achieving conduction between pin components 3 that are connected to the same conductive plate. When the pin component 3 slides with the socket hole 58, the guide pin 57 slides with the guide pin hole on the socket insulator 2 to guide the sliding between the pin component 3 and the socket hole 58, preventing the pin component 3 from deflecting when sliding with the socket hole 58 due to the elasticity of the mating end 31.

[0054] A locking mechanism 7 is fixedly installed at the middle position of the socket insulator 2 inside the socket housing 1. The locking mechanism 7 extends towards the front end of the socket housing 1 and penetrates through the socket housing 1. The locking mechanism 7 is used to cooperate with the plug to achieve locking. The front end of the locking mechanism 7 is provided with a locking hole 71. Two locking pins 72 are symmetrically provided on the inner wall of the locking hole 71, and the locking pins 72 protrude from the inner wall of the locking hole 71. A fixing sleeve 6 is fixedly fitted on the locking mechanism 7, so that the fixing sleeve 6 is relatively fixed to the socket housing 1. In other embodiments, the fixing sleeve 6 can also be directly fixed to the socket housing 1, and the locking mechanism 7 can be fixedly nested in the fixing sleeve 6. An annular insertion hole 11 for plug insertion is provided between the outer wall of the front end of the fixing sleeve 6 and the inner wall of the front end of the socket housing 1. Two anti-rotation grooves 61 extending in the insertion direction are symmetrically provided on the outer wall of the front end of the fixing sleeve 6 for limiting the plug when it is inserted and screwed. A sealing ring I12 is nested on the inner wall of the front opening of the socket housing 1 to achieve sealing when the plug and socket are inserted and after insertion, and to achieve sliding sealing between the socket and the plug.

[0055] The conductive component 5 is slidably fitted onto the fixed sleeve 6, which passes through the sliding hole 59. The sliding range is located between the inner wall of the socket insulator 2 and the front end of the socket housing 1. A sealing ring II 510 is nested within the inner wall of the sliding hole 59 on the fixed frame 51, achieving a sliding seal between the conductive component 5 and the fixed sleeve 6. A sealing ring III 511 is nested within the front end face of the fixed frame 51, achieving a seal between the conductive component 5 and the socket housing 1. When the headstock is not inserted, the front end of the socket is sealed by sealing rings II 510 and III 511. When the headstock is inserted, sealing is achieved during and after insertion by sealing rings II 510 and I 12.

[0056] An elastic element I4 is provided inside the socket housing 1. In this embodiment, the elastic element I4 is a corrugated spring. The elastic element I4 is sleeved on the conductive component 5 and the socket insulator 2. The front end of the fixing frame 51 is provided with a stop 512. One end of the elastic element I4 abuts against the socket insulator 2, and the other end abuts against the stop 512. When the head seat is not inserted, the elastic force of the elastic element I4 causes the front end face of the conductive component 5 to abut against the inner wall of the rear end of the socket housing 1. When the head seat is disengaged, the elastic element I4 is used to reset the conductive component 5.

[0057] plugs such as Figures 11-13 As shown, a locking screw 10 is rotatably mounted on the rear end of the plug housing 8. The locking screw 10 passes through the rear end of the plug housing 8, and a sealing ring IV 82 is nested in the inner wall of the through hole at the rear end of the plug housing 8 to achieve a rotational seal between the locking screw 10 and the plug housing 8. A handle 9 is fixedly mounted on the rear end of the locking screw 10, and an elastic element II 101 is provided between the handle 9 and the rear end face of the plug housing 8. In this embodiment, the elastic element II 101 is a helical spring, which is sleeved on the rear end of the locking screw 10. In this embodiment, the locking screw 10 and the handle 9 are fixed by a pin. The front end of the locking screw 10 passes through the inner cavity of the plug housing 8 and extends forward out of the plug housing 8. Under the elastic force of the elastic element II 101, the step on the locking screw 10 can abut against the inner wall of the plug housing 8. The front end of the locking screw 10 is provided with two spiral grooves 102 for sliding engagement with the corresponding locking pins 72 in the locking mechanism 7, and the rear end of the spiral grooves 102 is provided with a slot 103.

[0058] Insert the locking screw 10 into the locking hole 71, causing the locking pin 72 to insert into the corresponding spiral groove 102. Operate the handle 9 to rotate the locking screw 10, allowing the locking pin 72 to enter the spiral groove 102. As the locking screw 10 enters the locking hole 71, it drives the plug housing 8 to mate with the socket. The inner wall of the plug housing 8 is symmetrically provided with two anti-rotation platforms 81, which extend in the mating direction. When the plug housing 8 is inserted into the mating hole 11, the plug housing 8 slides into the mating hole 11, and the anti-rotation platform 81 slides into the anti-rotation slot 61, thus preventing rotation when the head and socket are mated. When the handle 9 is rotated during head and socket mating, the plug housing 8 is prevented from rotating, thereby allowing the plug housing 8 to mate smoothly with the socket. When the locking pin 72 moves to the rear end of the spiral groove 102, the plug housing 8 is fully engaged. At this time, the elastic element I4 is compressed. Under the elastic restoring force of the elastic element I4, the locking pin 72 is engaged in the slot 103 at the rear end of the spiral groove 102, thus achieving locking and preventing loosening. To unlock, press the handle 9 to disengage the locking pin 72 from the slot 103, and then rotate the handle 9 in the opposite direction to disengage the plug from the socket.

[0059] By engaging the elastic element II 101 with the step 104 on the locking screw 10, the step 104 can abut against the inner wall of the plug housing 8, achieving elastic limiting between the locking screw 10 and the plug housing 8 in the insertion direction, thus ensuring stable rotational engagement between the locking screw 10 and the plug housing 8. Through the elastic limiting of the elastic element II 101, during head-mount insertion, first slowly rotate the handle 9 while pressing it down. During rotation, only when the opening at the front end of the locking groove 102 aligns with the locking pin 72 can the locking pin 72 be pressed into the locking groove 102. At this point, the elastic force of the elastic element II 101 can be overcome, allowing the locking screw 10 to slide forward a certain distance. This indicates that the locking pin 72 and the locking groove 102 are aligned, and only the handle 9 needs to be rotated to allow the locking pin 72 to enter the locking groove 102, thus achieving head-mount insertion and locking. After locking, the elastic element II 101 has its own elastic pre-tightening force, and the locking pin 72 is stuck in the slot 103 at the rear end of the spiral groove 102. Through the elastic pre-tightening effect of the elastic element II 101, the loosening prevention under vibration environment can be achieved.

[0060] The mating and disassembly process of a connector assembly is as follows: When the socket is in an unplugged state, the conductive component 5 is pushed against the inner wall of the front end of the socket housing by the elastic component I4. At this time, the socket 58 of the upper plate conductive sheet 56 on the upper plate insulator 54 is plugged into the corresponding plug end 31 of the pin component 3, realizing mutual conduction between the designated holes, that is, realizing the conduction between the two plug components 3 that are plugged into the socket 58 of the same upper plate conductive sheet 56.

[0061] When the plug housing 8 is inserted into the mating hole 11 and the handle 9 of the plug is rotated and pressed, the locking pin 72 enters the spiral groove 102. Under the cooperation of the locking screw 10 of the plug and the locking mechanism 7 of the socket, the front end face of the plug housing 8 moves downward against the conductive part 5 of the socket. When it is screwed in place and locked, the mating end 31 of the pin part 3 passes through the intermediate insulator 53 and enters the bottom plate insulator 52. The insertion hole 58 of the upper plate conductive plate 56 on the upper plate insulator 54 is mated with the insulating part 32 of the corresponding pin part 3, so that the conduction relationship between the two pin parts 3 mated with the insertion hole 58 on the upper plate conductive plate 56 is broken. At this time, the insertion hole 58 of the bottom plate conductive plate 55 on the bottom plate insulator 52 is mated with the mating end 31 of the corresponding pin part 3, so that the designated hole positions are mutually connected, that is, the two pin parts 3 mated with the insertion hole 58 on the bottom plate conductive plate 55 are connected.

[0062] When the handle 9 of the plug is rotated in the opposite direction, the plug separates from the socket. The conductive component 5 inside the socket returns to its initial position under the action of the elastic component I4, and returns to the state where the two pin components 3 that are engaged with the socket 58 on the same upper plate conductive sheet 56 are connected. At this time, the two pin components 3 that are engaged with the socket 58 on the bottom plate conductive sheet 55 are disconnected.

[0063] The plug housing 8 is provided with a hanging hole structure 83, which is used to connect a marker or to hang the plug by connecting a rope.

[0064] This invention provides a connector assembly that enables the conversion of conduction and disconnection relationships between multiple signal groups through the insertion and disconnection of a plug and a socket. The socket of this connector assembly is designed with a conductive component 5, which includes multiple short-circuit boards (two short-circuit boards in this embodiment) and an intermediate insulator 53 separating adjacent short-circuit boards. During the insertion of the plug and socket, the conductive component 5 moves under the push of the plug. During this process, the conductive sheet in contact with the expansion hole component 3 inside the socket changes. Through the arrangement of the conductive sheets on the short-circuit boards and the configuration of multiple short-circuit boards, the conversion of conduction or disconnection relationships for certain specific signals is achieved. This solves the technical problem that existing connectors can only achieve independent signal on / off states and cannot achieve the conversion of conduction or disconnection relationships for specified contacts (i.e., pairs of conduction or disconnection pin components 3).

[0065] In other embodiments of the present invention, improvements are made based on the above embodiments. The pin component 3 can also be a common pin component, and the insertion end 31 of the pin component is a whole.

[0066] In other embodiments of the present invention, improvements are made based on the above embodiments. Two or more sockets 58 can be provided on the same conductive sheet, such as three or four sockets 58. Correspondingly, the same conductive sheet 515 can conduct three or four pin components 3.

[0067] In other embodiments of the present invention, improvements are made based on the above embodiments, and the shape of the conductive sheet 515 can be set as needed, without limitation.

[0068] In other embodiments of the present invention, improvements are made based on the above embodiments. The short-circuit board 513 can be configured with two or more layers, such as three or four layers. An intermediate insulator 53 is provided between two adjacent short-circuit boards 513. The conductive pieces 515 on each short-circuit board are distributed in different positions, that is, the projections of the conductive pieces 515 on each short-circuit board 513 on the connector mating end face do not completely overlap. This ensures that the projections of the conductive socket array composed of conductive sockets 58 on each short-circuit board 513 on the mating end face do not completely overlap. This allows the mating end 31 of the pin component 3 to be mated with the sockets 58 of the conductive pieces 515 on different short-circuit boards, enabling the mutual conversion between the conduction and disconnection relationships of two or more sets of signals. In addition, when three, four or more layers of short-circuit boards 513 are provided, it is sufficient to ensure that the conductive socket arrays on at least two short-circuit boards 513 do not completely overlap and can complete one signal switching. To ensure the mating end 31 is securely engaged with the sockets 58 on different shorting boards, the locking screw 10 and the locking mechanism 7 can be threaded together. This allows the mating end 31 to stop and remain engaged whenever it reaches a socket 58 on any shorting board. To facilitate identification of the mating end 31's position, several graduations can be distributed along the mating direction on the outer wall of the plug housing 8. Each graduation corresponds to a shorting board, and the distance between adjacent graduations represents the distance between adjacent shorting boards. The front face of the socket housing 1 can serve as a pointer to these graduations. When the operator inserts the plug housing 8 into the socket, they can determine the engagement of the mating end 31 with a socket 58 on a specific shorting board based on the graduations. The multi-layer shorting board 513 can be detachable or integrally integrated. In the integrated configuration, the short-circuit insulator is integrally integrated, and the conductive sheet 515 is fixed to the short-circuit insulator via injection molding.

[0069] In other embodiments of the present invention, improvements are made based on the above embodiments. The intermediate insulator 53 may be omitted from the insulator component. The conductive sheet 515 is nested within the corresponding short-circuit insulator 514, with both ends of the conductive sheet 515 located within the short-circuit insulator 514, avoiding contact and conduction with the conductive sheets 515 on adjacent short-circuit plates 513. When the conductive sheet 515 is placed within the short-circuit insulator 514, injection molding can be used. The inner wall of the insertion hole on the short-circuit insulator 514 coincides with the inner wall of the insertion hole on the conductive sheet 515. When the insertion end 31 of the pin component 3 is inserted into the insertion hole 58, the pin component 3 can conduct with the insertion hole 58.

[0070] In other embodiments of the present invention, improvements are made based on the above embodiments. The two locking pins 72 in the locking hole 71 can be replaced with spiral grooves 102, and the spiral grooves 102 on the locking screw 10 can be replaced with two symmetrically arranged locking pins 72. During the rotation of the locking screw 10, the locking pins 72 slide in the corresponding spiral grooves 102 to achieve insertion locking or unlocking.

[0071] In other embodiments of the present invention, improvements are made based on the above embodiments. The locking screw 10 and handle 9 can be omitted from the plug, or the handle 9 can be fixed to the plug housing 8. The locking mechanism 7 can be omitted from the socket. The fixing sleeve 6 is fixed to the socket. The inner wall of the plug housing 8 is provided with internal threads, and the front end of the fixing sleeve 6 is provided with external threads. The plug housing 8 is threadedly connected to the fixing sleeve 6. By screwing the plug housing 8, the plug housing 8 is inserted into the socket, thereby pushing the conductive component 5.

[0072] In other embodiments of the present invention, improvements are made based on the above embodiments. The conductive component 5 may omit the fixing frame 51, and the short-circuit plate 513 and the intermediate insulator 53 may be bonded together using an adhesive method. Alternatively, the intermediate insulator 53 may be omitted, and the short-circuit plate 513 may be directly bonded. One end of the elastic member I abuts against the rear end face of the conductive component 5, and the other end abuts against the front end face of the socket insulator 2. In other embodiments of the present invention, improvements are made based on the above embodiments. The front end face of the plug housing 8 is fixed on the front end face of the conductive component 5, or the front end of the socket housing 8 is rotatably mounted on the conductive component 5, so that the relative position of the plug housing 8 and the conductive component 5 remains unchanged in the insertion direction. In this case, the elastic element I4 can be omitted, and the plug and socket can be integrated. The conductive component 5 can be slid back and forth by the plug housing 8.

[0073] In other embodiments of the present invention, improvements are made based on the above embodiments. The insulating part 32 can be omitted from the pin component 3. The diameter of the insertion end 31 is larger than the diameter of the middle part of the pin component 3. When the insertion end 31 is inserted into the conductive socket 582 on the corresponding short circuit board, there is a gap between the middle part of the pin component 3 and the conductive socket 582 on other short circuit boards, which can achieve insulation through air.

[0074] In other embodiments of the present invention, improvements are made based on the above embodiments, such that the elastic element II101 can be omitted, so that the locking screw 10 can achieve axial limiting of the locking screw 10 through its own step and the retaining ring nested on its own outer wall.
