Description

Technical Field

[0001] This invention belongs to the field of connector technology, specifically relating to a gear-driven push-pull connector. Background Technology

[0002] In existing technologies, as the number of contacts (or terminals) in ultrasonic probe connectors increases, the insertion force required for connector mating also increases, making connector mating operations difficult. Therefore, the industry has developed connectors with low insertion force.

[0003] Existing low-insertion-force electronic connectors all employ a pre-insertion and then locking scheme: Existing technology one discloses a head assembly and its socket (application number: CN201711350486.1). When this connector is engaged, the terminal contacts are hidden inside the socket cover until the plug is fully inserted; then, a wrench is used to rotate the shaft, causing the shaft to drive the terminals to laterally shift and expose them to the socket insulation cover. As the shaft rotates, the lateral shift of the terminal contacts increases until electrical contact is made with the terminals on the plug. Simultaneously, the shaft also has a part with a hook-and-groove feature. After the shaft rotates, the hook-and-groove can engage the pin on the plug to achieve locking. Existing technology two discloses a rack-and-pinion zero-insertion-and-extraction-force connector (application number: CN202311065159.7). This technology requires a button to push to drive the rack to rotate the shaft. After the shaft rotates, the hook-and-groove can engage the pin on the plug to achieve locking.

[0004] The drawbacks of existing technology are as follows: Connectors require two separate actions during use. First, the plug must be inserted into place; second, a mechanism must be driven to rotate the shaft, achieving electrical contact and locking. This operation introduces the following problems: First, the insertion and separation efficiency is low, typically requiring two hands and placing high demands on the user. Second, if the shaft is not locked after insertion, the product is unusable. Third, if the shaft is not unlocked, the product cannot be separated, and forced separation will damage the plug and / or socket. Fourth, the driving mechanism makes the connector bulky, occupying space in the user's equipment. Fifth, in existing technology, the electrical contacts only make contact after the head and socket are inserted, resulting in little or no friction distance between the contacts. This makes the product sensitive to contamination (e.g., dirt on the electrical contacts can lead to poor contact), potentially causing a decline in contact performance. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art and provide a gear-driven push-pull connector. When this device is used, it only requires simple plugging and unplugging to realize the electrical switching and locking separation of the product; at the same time, it reduces the size of the product.

[0006] One objective of this invention is to provide a gear-driven push-pull connector, comprising a connector plug and a connector socket. The connector socket includes a socket housing and a socket signal element disposed within the socket housing. A camshaft is also disposed within the socket housing. The camshaft, by rotating, pushes the contact position of the socket signal element to shift, thereby enabling signal contact with the plug signal element of the connector plug. A rack is also disposed within the socket housing, which drives the camshaft to rotate. A pin is fixedly disposed on the camshaft. A pin adapted to the pin is disposed within the plug housing. One end face of the rack is the driving surface; When the head and socket are engaged, the connector plug can abut against the drive surface to push the rack to move along the engagement direction of the connector plug, thereby driving the camshaft to rotate synchronously, so that the plug signal element and the socket signal element make electrical contact, and at the same time the pin hook rotates synchronously with the camshaft to hook onto the pin. When the head unit separates, the pin can push the hook to rotate, thereby driving the camshaft to rotate synchronously in the opposite direction, so that the plug signal component and the socket signal component are separated, and the pin and the hook are simultaneously disengaged.

[0007] As a preferred embodiment, the driving surface is positioned opposite to the mating direction of the connector plug.

[0008] As a preferred embodiment, the plug housing has a plug end forming an abutment portion that mates with the drive surface, the abutment portion being used to drive the rack to move by abutting with the drive surface.

[0009] As a preferred embodiment, the plug housing is further provided with a shielding plate at the insertion end, which can drive the rack to move by abutting against the driving surface.

[0010] As a preferred embodiment, the pin can drive the rack to move by abutting against the drive surface.

[0011] As a preferred embodiment, a pin groove corresponding to the pin position is formed on the driving surface.

[0012] As a preferred embodiment, the rack is installed inside the socket housing and slides in engagement with the socket housing, so that the rack can move within the socket housing along the insertion / removal direction of the headstock.

[0013] As a preferred embodiment, the inner wall of the socket housing is provided with a sliding groove along the insertion direction, and the two sides of the rack are installed in the sliding groove; The rack includes two parallel and fixedly connected rib racks. The opposite sides of the rib racks are provided with external teeth II along the length direction, and the opposite sides of the rib racks are provided with rib slides along the length direction. The rib slides are slidably engaged with the slide grooves.

[0014] As a preferred embodiment, a locking platform is provided at the end of the rib rack away from the driving surface, and a locking plate adapted to the locking platform is fixedly provided inside the socket housing. When the head is inserted or removed, the locking platform can cooperate with the locking plate to lock or unlock.

[0015] As a preferred embodiment, the locking platform includes a guide surface facing the locking plate side and a locking surface facing away from the locking plate side.

[0016] As a preferred embodiment, the locking plate includes a mounting portion and spring portions extending to both sides from the mounting portion. The spring portions engage with the locking table to lock or unlock. The spring portions include a support section, an elastic section, and a sliding section connected in sequence. The mating surface between the sliding section and the locking table is a rounded surface transition.

[0017] As a preferred embodiment, a protruding post is provided at one end of the rib rack away from the driving surface, and a locking piece adapted to the protruding post is fixedly provided inside the socket housing. Clamping spring assemblies are provided on both sides of the locking piece, and the clamping spring assemblies are provided with elastic gaps for the protruding post to enter.

[0018] As a preferred embodiment, the clamping elastic component includes a first clamping spring and a second clamping spring arranged opposite to each other. An elastic gap is formed between the first and second clamping springs, through which a protrusion enters. When the protrusion enters the elastic gap, the first and second clamping springs are squeezed and separated outward. After the protrusion enters the elastic gap, the first and second clamping springs move closer to each other under their own elastic force to prevent the protrusion from detaching.

[0019] As a preferred embodiment, a locking platform is provided at the end of the rib rack away from the driving surface, and an elastic pin adapted to the locking platform is fixedly provided inside the socket housing. The elastic pin includes a sleeve and elastic pin heads that can extend outward from both ends of the sleeve. The opposite sides of the two elastic pin heads respectively abut against the two ends of a spring provided inside the sleeve.

[0020] As a preferred embodiment, the ends of the two convex toothed racks are connected by a connecting bridge. An auxiliary separation spring adapted to the connecting bridge is fixedly installed inside the socket housing. When the head is inserted, the connecting bridge squeezes the auxiliary separation spring to deform it and store the deformation energy. When the head is separated, the auxiliary separation spring is used to provide a pre-separation force in the separation direction for the connector head.

[0021] As a preferred embodiment, the pin includes a hook portion and a gear portion, the hook portion and the gear portion are integrally formed, the outer edge of the gear portion is provided with external teeth I, one side of the hook portion is provided with a hook groove, the hook groove is engaged with the pin, one side of the hook groove is provided with an inclined surface, the pin is engaged with the inclined surface to push the pin to rotate, thereby realizing the unlocking and separation of the head seat.

[0022] As a preferred embodiment, two camshafts are arranged in parallel, with each camshaft located between the two rows of socket terminals of each set of socket signal components. The outer shaft surface of the camshaft abuts against the two rows of socket terminals. When the camshaft rotates and drives the two rows of socket terminals closer together, the socket signal component and the plug signal component are separated. When the camshaft rotates and pushes the two rows of socket terminals away from each other, the socket signal component and the plug signal component make electrical contact.

[0023] As a preferred embodiment, at least one of the two camshafts extends outward to form an extension section. The rotation of the extension section causes the rack to slide within the socket housing, thereby driving the pin to rotate.

[0024] A second objective of this invention is to provide a connector socket, which is the connector socket of the gear-driven push-pull connector described in any of the above claims.

[0025] A third objective of this invention is to provide a connector plug, which is the connector plug of the gear-driven push-pull connector described in any of the above claims.

[0026] Beneficial effects This invention, through structural improvements, allows the product to achieve electrical connection / disconnection and locking separation between the head and socket simultaneously with a single insertion / removal action during use. The operation is simple and user-friendly. During head-socket separation, the pin shaft drives the hook to rotate, directly achieving separation and reducing the risk of damage to the plug and socket due to failure to unlock before operation. It eliminates the need for an additional camshaft drive structure, resulting in a smaller product size and less space required by the user's equipment. Furthermore, because the electrical connection / disconnection and locking separation actions are simultaneous, there is a certain friction distance between the socket and plug signal components along the insertion / removal direction during the insertion / removal process. This friction self-cleans the contact points of the signal components during insertion and removal, making the product less sensitive to dirt and effectively improving the reliability of the insertion / removal process.

[0029] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0030] It should be noted that, unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "a," "an," or "the," and similar words used in the specification and claims of this patent application do not express a limitation of quantity, but rather indicate the presence of at least one. Terms such as "comprising" or "including" indicate that the elements or objects preceding "comprising" encompass the elements or objects listed following "comprising" or "including" and their equivalents, but do not exclude other elements or objects having the same function.

[0031] Example 1 like Figure 1-14 As shown, this embodiment provides a gear-driven push-pull connector, including a connector plug 2 and a connector socket 1 adapted to be plugged into it. The connector socket 1 includes a socket housing 11 and a socket signal element 12 disposed in a cavity 112 of the socket housing 11. A camshaft 13 is also disposed in the socket housing 11. The camshaft 13 contacts the inner side of the socket signal element 12. Each camshaft 13 is located between two rows of socket terminals 121 of the corresponding socket signal element 12. The axial surface of the camshaft 13 abuts against the opposite end of the two rows of socket terminals 121 of the socket signal element 12. Through the rotation of the cam structure of the camshaft 13, the horizontal width of the camshaft 13 in the radial direction (the horizontal width is the camshaft 13 along the...) is shown in the figure. Figure 8 , 10 When the width in the D direction changes, it can push the contact position of the socket signal element 12 to shift to both sides, thereby causing the socket signal element 12 to abut and separate from the plug signal element 22 of the adapter connector plug 2. Specifically, when the camshaft 13 rotates and pushes the two rows of socket terminals 121 closer, it can achieve separation from the plug terminals 221. When the camshaft 13 rotates and pushes the two rows of socket terminals 121 away, it can achieve electrical contact with the plug terminals 221.

[0032] In this embodiment, a rack 14 is also provided inside the socket housing 11. The rack 14 can drive the camshaft 13 to rotate, thereby causing the camshaft 13 to rotate around its axis. A pin 15 is also fixedly provided on the camshaft 13. The pin 15 is provided with a hook part 151 and a gear part 154. A pin 23 corresponding to and adapted to the pin 15 is provided inside the plug housing 21. After the pin 15 rotates with the camshaft 13, the hook part 151 will be hooked at the pin 23, thereby realizing the locking of the head seat.

[0033] In this design, the end face of the rack 14 near the insertion end is the driving surface 141. The connector plug 2 abuts against this driving surface 141, thereby providing driving force for the rack 14 to drive the camshaft 13 to rotate. When the head and seat are inserted, the connector plug 2 abuts against the driving surface 141 and pushes the rack 14 to move into the cavity 112 of the socket housing 11 along the insertion direction, thereby driving the camshaft 13 to rotate, so that the plug signal element 22 and the socket signal element 12 make electrical contact. The pin hook 15 rotates synchronously with the rotation of the camshaft 13 and finally hooks onto the pin 23. When the head and seat are separated, the pin 23 moves in the opposite direction (along the direction of pull-out of the connector plug 2), thereby pushing the pin hook 15 to rotate in the opposite direction, thereby driving the camshaft 13 to rotate synchronously in the opposite direction. The socket signal element 12 swings in the opposite direction, so that the plug signal element 22 and the socket signal element 12 are separated. At the same time, the pin 23 and the pin hook 15 are simultaneously disengaged. Through the above structural improvements, this solution enables electrical connection and disconnection between the head and the base, as well as synchronous locking and separation, with only one plug-in / plug-out operation. This reduces the difficulty of operation, avoids product damage that may be caused by misoperation, and is more user-friendly.

[0034] In this design, the protective cover 19 is located at the port of the socket housing 11. The contacts of the socket terminal 121 extend into the interior of the protective cover 19 and can extend outward from the windows arranged on the side of the protective cover 19, thereby making electrical contact with the corresponding plug terminal 221 extending into the cavity 112. The two ends of the protective cover 19 are provided with shaft grooves 192, which cooperate with the shaft grooves of the socket housing 11. The protective cover 19 and the socket housing 11 are fixedly connected by screws 191 to form a complete shaft cavity for installing the end of the camshaft 13. The shaft cavity is clearance-fitted with the end of the camshaft 13 to realize the rotation of the camshaft 13.

[0035] This design allows for single-handed, single-step operation. Connecting and locking the headstock is achieved simply by pushing the connector plug 2 into the connector socket 1. Unlocking is achieved by simply pulling out the connector plug 2. This structure also eliminates the need for the camshaft 13 to extend beyond the socket housing 11, resulting in a smaller product size and saving installation space. Furthermore, based on this structure, the socket signal element 12 and the plug signal element 22 have already made initial contact before the headstock is fully locked. As the headstock signal elements make contact and remain fully engaged, there is still a short insertion distance. The contact friction between the socket signal element 12 and the plug signal element 22 provides a self-cleaning effect on the contact surfaces during the insertion and removal process. Therefore, the contact points of this design are not sensitive to dirt, improving contact reliability.

[0036] In this solution, the pin 15 can be implemented as follows: The pin 15 is fixed on the camshaft 13. The pin 15 includes a hook portion 151 and a gear portion 154, wherein the hook portion 151 and the gear portion 154 are integrally formed. The outer edge of the gear portion 154 is provided with external teeth I 155, which are used to mesh with external teeth II 143 of the rack 14. A hook groove 153 is provided on one side of the hook portion 151. The hook groove 153 is used to hook the pin 23 when the head seat is inserted into place. On the hook portion 151, a slope 152 is provided on one side of the hook groove 153. The function of the slope 152 is to allow the pin 23 to push the pin 15 to rotate when the pin 15 is disengaged from the pin 23, thereby achieving the unlocking and separation between the head seat and the pin 23. It should be noted that the structure of the pin 15 in this solution is not limited to the above structure.

[0037] In a typical embodiment of the present invention, the rack 14 may be implemented as follows: the rack 14 includes two parallel rib racks 142, which are connected by a connecting part. The rib racks 142 are provided with external teeth II 143 along their length direction. Preferably, the external teeth II 143 are located on the opposite end faces of the two rib racks 142. The end face of the rack 14 near the insertion end is a driving surface 141. The function of the driving surface 141 is to abut against the connector plug 2, thereby pushing the rack 14 to slide along the insertion direction through the connector plug 2.

[0038] In this invention, the connector plug 2 has a pin 23 at its insertion end. The pin 23 is positioned along the length of the connector plug 2 and engages with the driving surface 141. When the connector head is inserted, the pin 23 and the driving surface 141 move from a separated state to a contact state. During continued insertion, the pin 23 pushes the rack 141 to slide into the socket housing 11 along the insertion direction. Since the rack 141 meshes with the gear part 154, it can drive the camshaft 13 to rotate. At this time, the pin hook 15 on the camshaft 13 rotates, and the hook part 151 hooks onto the pin 23, achieving hook connection between the hook groove 153 and the pin 23. To achieve better engagement between the pin 23 and the driving surface 141, the driving surface 141 is also provided with a pin groove 147, where the pin 23 abuts against the pin groove 147, thereby achieving stable engagement between the pin 23 and the driving surface 141 of the rack 14.

[0039] In this design, the two sides of the rack 14 have raised ribs 142 with opposite sides forming raised rib slides 149. The inner wall of the cavity 112 of the socket housing 11 is provided with a slide groove 111. The length of the slide groove 111 is set along the insertion direction. The raised rib slides 149 and the slide groove 111 can slide together to ensure the stability of the sliding direction of the rack 14 during the process of being pushed by the connector plug 2. In order to facilitate the assembly of the rack 14 into the slide groove 111, a V-shaped opening is formed at the entrance of the slide groove 111 to facilitate the assembly of the rack 14. In addition, in order to avoid the rack 14 from obstructing the rotation of the pin 15, a relief groove 148 is provided on one side of the drive surface 141 of the rack 14. The function of the relief groove 148 is that when the pin 15 rotates, its hook part 151 passes through the drive surface 141 through the relief groove 148, thereby realizing the hooking of the pin 15 and the pin 23. In order to fit the structure of the connector plug 2, a rib groove 140 that mates with the rib of the connector plug 2 is also provided on one side of the clearance groove 148. In an embodiment without drawings, the clearance groove 148 and the rib groove 140 can also be flush with each other to form a complete square groove, depending on the design requirements.

[0040] In this embodiment, before the head seat is inserted, the camshaft 13 is not rotated under force, and the pin hook 15 is hidden inside the rack 14, specifically between the two protruding rib racks 142. When insertion begins, the pin 23 of the connector plug 2 will abut against the driving surface 141 and enter the pin groove 147 of the rack 14. Then, driven by the insertion force of the connector plug 2, the rack 14 slides along the direction of the slide groove 111 and enters the socket housing 11 more deeply. The rack 14 drives the pin hook 15 to rotate through its external teeth II 143. When the pin hook 15 rotates, the hook part 151 will extend from the relief groove 148, and the camshaft 13 rotates. The axial surface of the outer wall camshaft 13 abuts against the socket signal element 12 and pushes it to wobble, so that its contact point will be laterally offset as shown in the figure and make electrical contact with the plug signal element 22. During the further insertion of the head unit, since the socket signal element 12 and the plug signal element 22 have already made contact, the contacts will generate relative friction during the subsequent insertion process until the insertion is complete and the friction stops. When the hook groove 153 of the pin 15 and the pin 23 make contact and fit together, the insertion of the head unit is completed.

[0041] In this embodiment, in order to better achieve the locking effect of the head-end connection between the connector plug 2 and the connector socket 1, a locking plate 16 is also installed inside the socket housing 11. A locking platform 144 is also provided at the end of the protruding rib rack 142 away from the driving surface 141. The locking platform 144 is located at the end of the protruding rib rack 142. The locking platform 144 includes a guide surface 1441 and a locking surface 1442. After the guide surface 1441 abuts against the locking plate 16, it squeezes the locking plate 16 to deform and then passes over the sliding section 164 of the locking plate 16, so that the locking platform 144 and the locking plate 16 are locked, thereby improving the locking force between the head-ends.

[0042] In this design, the locking piece 16 adopts the following structure: The locking piece 16 includes a mounting part 161, which is used to fix the locking piece 16 to the inner wall of the socket housing 11. The mounting part 161 extends to both sides to form a spring piece, which is suspended on both sides. The spring piece can cooperate with the locking table 144. The spring piece has a support section 162, an elastic section 163 and a sliding section 164 formed sequentially from one side of the mounting part 161 outward. An angle structure is formed at the connection of the mounting part 161, the support section 162 and the elastic section 163. The sliding section 164 is located at the end of the elastic section 163 and is used to directly contact the locking table 144. Therefore, the outer circular surface of the sliding section 164 is a smoothly transitioned sliding surface to cooperate with the guide surface 1441, thereby facilitating sliding locking when the head seat is inserted. After the locking platform 144 passes the sliding section 164, the locking surface 1442 abuts against the locking platform 144. Compared with the locking force obtained by the hook 15 and pin 23 alone, the locking force obtained by the locking platform 144 and the locking plate 16 can maintain a stronger locking force between the head and the base.

[0043] In this embodiment, to better illustrate the mating relationship between the locking platform 144 and the locking plate 16, the following description is provided in conjunction with the accompanying drawings: When the rack 14 slides along the engagement direction, the guide surface 1441 of the locking platform 144 on the rack 14 contacts the sliding surface of the locking plate 16, causing the locking plate 16 to undergo elastic deformation and store elastic potential energy. The sliding section 164 is oriented towards the product center (the product center refers to the position of the product's axis of symmetry, which is...). Figure 7The position indicated by point E in the middle moves. As the rack 14 continues to slide, when the protrusion of the sliding surface of the locking piece 16 passes the protrusion of the locking platform 144 of the rack 14, the sliding section 164 moves away from the center of the product under the drive of elastic force. The sliding surface of the locking piece 16 fits against the locking surface 1442 of the rack 14 and stores elastic potential energy. When the engagement is completed, the locking piece 16 and the rack 14 remain in contact under the elastic potential energy, realizing product locking. To meet different usage needs, when a large insertion force and a small extraction force are required, the acute angle α between the guide surface 1441 of the locking platform 144 and the insertion direction can be made larger than the acute angle b between the locking surface 1442 of the locking platform 144 and the separation direction, and the angle B between the elastic segment 163 of the locking plate 16 and the insertion direction can be an obtuse angle; conversely, when a small insertion force and a large extraction force are required, the acute angle α between the guide surface 1441 of the locking platform 144 and the insertion direction can be made smaller than the acute angle b between the locking surface 1442 of the locking platform 144 and the separation direction, and the angle B between the elastic segment 163 of the locking plate 16 and the insertion direction can be an acute angle (e.g., Figure 12 (As shown). In addition, in this solution, the angle A between the support section 162 and the mounting surface of the mounting part 161 (the mounting surface refers to the plane at which the mounting part 161 is fixed) is an acute angle, which is beneficial for the elastic section 163 of the locking piece 16 to move towards the center of the product when it is inserted, and prevents the elastic section 163 from hard interference with the locking platform 144 of the rack 14, which would lead to locking failure.

[0044] In this design, when the connector head separates, the connector plug 2 is pulled outward along the separation direction, and the pin 23 of the connector plug 2 retracts. The angle C between the inclined surface 152 of the pin hook 15 and the separation direction is an acute angle (refer to...). Figure 14 The pin 23 pushes the inclined surface 152 of the pin hook 15, generating a component force facing the center of the product, which drives the pin hook 15 to rotate. When the pin hook 15 rotates, it drives the camshaft 13 to rotate, causing the contacts of the connector head to separate; at the same time, it drives the rack 14 to slide in the separation direction. When the separation force overcomes the locking force of the locking plate 16, the locking platform 144 of the rack 14 separates from the locking position of the locking plate 16, and the connector head is separated.

[0045] Example 2 Based on the connector head of Embodiment 1, in order to increase the locking force between the connector heads, the rack 14 can also adopt another implementation method: such as... Figure 15As shown, a protruding post 145 is provided at the end of the ribbed rack 142 away from the driving surface 141. The protruding posts 145 of the two ribbed racks 142 are arranged opposite to each other. The protruding post 145 has a cylindrical structure. The locking piece 16 includes a mounting part 161 and a clamping spring assembly 165 provided on the mounting part 161. The clamping spring assembly 165 corresponds to the position of the protruding post 145. The clamping spring assembly 165 forms a gap for the protruding post 145 to enter. Specifically, the clamping spring assembly 165 includes a first clamping spring and a second clamping spring. A gap is formed between the first and second clamping springs. The elastic gap through which the protrusion 145 enters causes the first and second clamping springs to be squeezed outwards and separated when the protrusion 145 enters the elastic gap. The protrusion 145 pushes against the clamping springs on both sides. After the protrusion 145 enters, the first and second clamping springs move closer to each other under their own elastic force, thus clamping and confining the protrusion 145 between the two clamping springs. When the head seat needs to be separated, a certain pull-out force is required to push the clamping springs against each other and separate them, thereby overcoming the locking force of the clamping spring assembly 165. The protrusion 145 then disengages from the clamping spring assembly 165. To better achieve the cooperation between the clamping springs and the protrusion 145, the opposite ends of the clamping springs are close together and each is provided with a rolled structure 166. The width of the elastic gap between the two parallel rolled structures 166 is smaller than the cross-sectional diameter of the protrusion 145 when not subjected to other external forces, thus forming a limiting lock for the protrusion 145. Meanwhile, the rolled structure 166 and the protruding post 145 can facilitate the operation of head seat insertion to a certain extent, so that the locking force is kept within an appropriate range.

[0046] Example 3 Based on the connector head in Embodiment 1, the locking plate 16 that mates with the locking plate 144 can also be replaced by other methods, such as... Figure 16 As shown, for example, the locking piece 16 is replaced by a resilient pin 17, which runs along the width direction of the connector socket 1 (the width direction is the same as the locking piece 16). Figure 10 The elastic pin 17 is configured in the same direction as D in the figure. It includes a sleeve 171 with both ends through it. The sleeve 171 is fixed inside the socket housing 11. The elastic pin head 172 is located at both ends of the sleeve 171 and can protrude outward. A spring (not shown in the figure) is also provided inside the sleeve 171. The spring is arranged along the length of the sleeve 171. The two ends of the spring 173 abut against the elastic pin head 172. When the elastic pin head 172 is compressed, it can retract into the sleeve 171. The elastic pin 17 can cooperate with the rack 14 with the locking platform 144. When the head seat is inserted, the elastic pin head 172 can abut against the guide surface 1441. When compressed, the elastic pin head 172 retracts into the sleeve 171. When the elastic pin head 172 passes the locking platform 144, the elastic pin head 172 abuts against the locking surface 1442 to lock the head seat.

[0047] Example 4 Based on the connector head in Embodiment 1, when the head is inserted, the driving method of the pin 13 engaging with the driving surface 141 can be replaced by engaging with the rack 14 through other parts of the connector plug 2, for example... Figure 17-20 As shown, the plug housing 21 of the connector plug 2 is in contact with the drive surface 141. This method has the following advantages: when the connection between the pin 23 and the plug housing 21 is achieved by interference fit, the long-term pushing of the drive surface 141 by the pin 23 may cause the fixed connection at the root of the pin 23 to loosen. However, by directly engaging the plug housing 21 with the drive surface 141, the pin 23 is only needed to push the pin hook 15 to rotate when unlocking, thus extending the product's service life.

[0048] When driven by the plug housing 21, the rack 14 is adapted as follows: the shape of the driving surface 141 of the rack 14 is adapted to the plug housing 21, and the rib rack 142 forms a protrusion adapted to the plug housing 21 near the driving surface 141. The end face of this protrusion and the end face of the connecting part together constitute the driving surface 141. In addition, when the plug housing 21 is provided with a shielding plate 24, if the height of the shielding plate 24 exceeds the end face of the plug housing 21, the shielding plate 24 will directly contact the driving surface 141 of the rack 14. In this case, the shielding plate 24 will directly contact the rack 14 and drive the rack 14 to move.

[0049] Example 5 In this embodiment, it is also considered that when the user has a lower requirement for the locking force of the head seat and needs to reduce the pull-out force, the locking piece 16 in embodiments 1-4 can be removed, and an assist separation spring 18 can be installed in the socket housing 11 to provide separation assistance, such as Figure 21-24As shown, in order to cooperate with the assist separation spring 18, the rack 14 adopts the following structure: the rack 14 includes two rib racks 142, which are connected by a connecting part. The rib racks 142 are provided with external teeth II 143 along their length direction. Preferably, the external teeth II 143 are located on the opposite end faces of the rib racks 142. A rib slide 149 is formed on the opposite side of the rib racks 142. The end face of the rack 14 near the insertion end is the driving surface 141. The function of the driving surface 141 is to abut against the connector plug 2, thereby pushing the rack 14 to slide along the insertion direction through the connector plug 2. The end of the ribbed rack 142 is connected by a connecting bridge 146. After the rack 14 slides into the socket housing 11, the connecting bridge 146 engages with the assisted separation spring 18. The assisted separation spring 18 includes a support portion 181, a deformable portion 182, and an abutment portion 183 connected in sequence. The support portion 181 is fixedly connected to the socket housing 11. The deformable portion 182 includes a vertical section and an inclined section connected together. Preferably, the vertical section and the inclined section form an obtuse angle. The vertical section is connected to the support portion 181. The inclined section ends are connected to the abutment portion 183. After the headstock is inserted, the connecting bridge 146 will press against the assisted separation spring 18. After the connecting bridge 146 contacts the abutment portion 183, the assisted separation spring 18 will deform. When the headstock is fully inserted, the spring stores deformed state energy, generating a pre-separation force in the separation direction on the connecting bridge 146. When the connector plug 2 is pulled out to achieve headstock separation, the assisted separation spring 18 will release deformed state energy. The pre-separation force assists the connector plug 2 in being pulled out. Figure 25 , 26 As shown, compared with the prior art which sets the assisted separation spring 18 on the cover 19, the prior art requires the design of a spring slot 194 on the cover 19. The spring slot 194 is used to install the assisted separation spring to assist the head seat in separation. However, under this structure, the strength of the cover 19 will be reduced to a certain extent due to the design of the spring slot 194. In this solution, there is no need to reserve a spring slot on the cover 19. The assisted separation spring 18 is designed and installed in the socket housing 11 and forms a cooperation with the rack 14. The solid diagram 193 in the cover 19 of this solution (there is no need to design a hollow spring slot here), thereby improving the structural strength of the cover 19.

[0050] Example 6 When the user equipment does not have high requirements for connector size, the following implementation method can be adopted, which can be compatible with existing technical solutions while maintaining the structure of the above embodiments, such as... Figure 27As shown, this invention achieves a one-step locking or unlocking operation while being compatible with existing two-step locking or unlocking separation schemes. Specifically, one end of the camshaft 13 extends outward to form an extension section 131. This extension section 131 drives the locking or unlocking separation. The camshaft 13 with the extension section 131 acts as the drive shaft, while the other camshaft 13 acts as the driven shaft. The extension section 131 can be used to drive the camshaft 13 to rotate, similarly achieving locking and unlocking separation of the headstock. When the camshaft 13 rotates, it drives the gear section 154 to rotate, causing the pin hook 15 to separate from the pin 23. The external teeth I 155 on the pin hook 15 drive the rack 14 to move in the unlocking direction and push out the connector plug 2, thus achieving unlocking and separation. The operator can choose between a one-step locking / unlocking separation method or a two-step locking / unlocking separation method according to their operating habits and application scenarios. The one-step locking and unlocking separation method involves directly plugging and unplugging the connector plug 2. The two-step locking and unlocking separation method involves driving the camshaft 13 to rotate through the extension section 131, thereby achieving locking or unlocking separation of the head seat. In specific cases, such as when the user requires a high locking force, the angle C between the separation direction and the inclined plane 152 in the figure is designed to be a right angle or an obtuse angle. This type of pin hook structure requires a large separation force, and it is difficult to achieve head seat separation by direct pulling. Therefore, in this case, when head seat separation is required, the above two-step unlocking separation method can be implemented, and the head seat can be unlocked and separated by using a wrench through the extension section 131.
