Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and in particular relates to a quick-lock connector that prevents oblique insertion and oblique withdrawal. Background Art

[0002] When the existing connectors are plugged in, the plug and the socket are prone to deformation, breakage, or pin stacking due to oblique insertion and withdrawal. The anti-oblique insertion function is often achieved by increasing the shell depth of the plug / socket, adding guide lines in the plug and socket, or providing a special external guide mechanism. In the prior art, although there are various guide structures, the operator needs to align them accurately before plugging them in, which is inconvenient to operate and reduces the operator's work efficiency. The existing connectors are respectively provided with locking structures and guide structures, which occupy a large space and cannot meet the situation of limited installation space. In addition, during the plug-in operation, it is necessary to align the plug-in before locking, which is inconvenient to operate and reduces the plug-in efficiency. It is urgent to develop a connector that can prevent oblique insertion and withdrawal and can be installed in a limited space and plugged in quickly. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a quick-lock connector that prevents oblique insertion and oblique withdrawal, which can realize the function of preventing oblique insertion and oblique withdrawal and has a quick and easy locking function.

[0004] The purpose of the utility model is to be achieved by adopting the following technical solutions. According to the utility model, an anti-oblique insertion and oblique withdrawal quick lock connector is proposed, including a plug and a socket, the plug including a plug housing, the outer side wall of the plug housing is provided with a guide groove extending in the insertion direction, the plug housing is provided with a shaft-like member, a locking plate is rotatably arranged on the shaft-like member, the locking plate is located on the outer side of the guide groove, an elastic member is sleeved on the shaft-like member, one end of the elastic member is against the inner side wall of the locking plate, and the other end is against the outer side wall of the plug housing, and the elastic member is used to provide the locking plate with a tendency to rotate from the unlocking position to the locking position; the socket includes a socket housing, both sides of the plug-in end of the socket housing are provided with protruding plug-in end faces and guide keys used to be nested in the guide groove, and the outer side wall of the socket housing is provided with a locking platform for clamping on the locking plate.

[0005] Compared with the prior art, the utility model is advantageous in that: when the plug and the socket of the utility model are plugged in, due to the elastic setting of the locking piece, if the oblique insertion angle of the plug is too large, the locking piece can be opened to expand the distance between the locking piece and the guide groove, so that the guide key can be inserted between the locking piece and the guide groove during operation, and under the restoring force of the elastic member, the distance between the guide groove and the locking piece tends to be reduced, which has a guiding effect on the oblique insertion operation of the operator. When the locking piece returns to its natural state, the inclination angle between the guide groove and the guide key is reduced to a normal range, and then, as the guide key is gradually nested in the guide groove, the inclination of the plug gradually returns to normal. The plug and the socket are aligned until there is no tilt between them, and then the plug and the socket are correctly plugged in. Therefore, the utility model can avoid oblique plugging and pulling out of the contacts and thus avoid damage to the connector, while being easy for the operator to operate, and avoids the problem in the prior art that there is a guide structure but it is difficult to align the operation; while plugging in, the locking piece can be opened under the action of the plugging force, and when the plug is in place, the locking piece returns to its original position to achieve locking, and the operation is convenient; the locking structure (locking piece, shaft-shaped piece, elastic piece) is located outside the guide structure (guide groove), and the two are integrated, occupying a small space, and the locking structure can achieve locking while guiding the plugging, and the operation is quick.

[0006] Furthermore, the insertion end of the guide groove is provided with a guide chamfer.

[0007] Compared with the prior art, the utility model is advantageous in that the guide chamfer enlarges the opening of the guide groove, making it easier to insert the guide key on the socket.

[0008] Furthermore, the locking piece has a vertically bent engaging wall at the engaging end thereof and is engaged with the locking platform.

[0009] Furthermore, a stop boss is provided at the front end of the locking piece close to the plug-in end, and when the locking piece is in the locking position, the stop boss abuts against the outer side wall of the plug housing.

[0010] Compared with the prior art, the utility model is advantageous in that it prevents the front end of the locking plate from being too close to the side wall of the plug housing under the elastic force of the elastic member, thereby preventing the cavity between the locking plate and the guide groove from being too small to allow the guide key to be inserted into the guide groove.

[0011] Furthermore, the rear end of the plug housing is inserted into the shield housing, and the plug housing and the shield housing are connected by screws.

[0012] Furthermore, the locking plate is provided with an avoidance hole for avoiding the screw.

[0013] Furthermore, a blocking plate is slidably arranged in the avoidance hole, and the blocking plate includes two mutually perpendicular side plates, wherein one side plate is slidably matched with the inner wall of the locking plate; the other side plate is slidably penetrated into the avoidance hole, and the width of the end of the other side plate extending out of the avoidance hole is greater than the width of the avoidance hole.

[0014] Compared with the prior art, the utility model is advantageous in that: when plugging in, the baffle is pushed forward to avoid it blocking the avoidance hole, so that the rear end of the locking plate is pressed down smoothly; after the plug and the socket are locked, the baffle is pulled backward to block the avoidance hole, and the baffle is squeezed and arranged between the screw and the rear end of the locking plate under the elastic force of the elastic member, so that the position of the baffle is fixed. At this time, the avoidance hole has been blocked. If the locking plate is accidentally touched, the rear end of the locking plate will not be pressed down and the front end of the locking plate will not be tilted because the baffle blocks the avoidance hole, thereby achieving stable locking of the plug and the socket; when unlocking, the baffle is pushed forward so that the baffle no longer blocks the avoidance hole, so that the rear end of the locking plate can be pressed down to achieve unlocking.

[0015] Furthermore, the shield shell is provided with an avoidance groove for avoiding the pressing and unlocking end of the locking piece.

[0016] Furthermore, the thickness of the guide key gradually decreases in the protruding direction, the inner side wall of the guide key is perpendicular to the insertion end face, and the outer side wall is inclined.

[0017] Compared with the prior art, the utility model is advantageous in that after the guide key is inserted into the guide slot, the inner side wall of the guide key can fit the bottom of the guide slot, ensuring that the plugging direction of the plug is not tilted.

[0018] Furthermore, a locking platform is protruded from the side wall of the socket housing, the thickness of which gradually decreases in the protruding direction, the locking platform is inclined toward the side wall of the plugging end, and the side wall away from the plugging end is perpendicular to the side wall of the socket housing.

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] The utility model provides an embodiment of an anti-oblique insertion and oblique withdrawal quick lock connector, as shown in Figures 1 to 11 As shown in FIG. 1 , the connector includes a plug and a socket that are locked together, and the plug-in end of the plug and the socket is used as the front end for explanation. Figures 1 to 4 As shown, the plug includes a plug housing 1, and both side walls of the plug housing 1 are provided with guide grooves 2, which extend along the insertion direction. The guide groove 2 extends backward from the front end surface, and the front end bottom of the guide groove 2 is provided with a guide chamfer 201, which enlarges the opening of the guide groove 2 to facilitate the insertion of the guide key on the socket.

[0047] The plug housing 1 is provided with an axial member, on which a locking piece 5 is rotatably arranged. The axial member may be a pin, a shaft, a pin, etc. In this embodiment, a pin is arranged on the plug housing 1. A mounting boss 3 is arranged on the side wall where the guide groove 2 is located. The mounting boss 3 is located on both sides of the guide groove 2. The mounting boss 3 protrudes from the side wall of the plug housing and extends in the front-to-back direction. The two mounting bosses 3 on the same side are penetrated and fixed with the same pin 4. A locking piece 5 is rotatably arranged on the pin 4. The locking piece 5 is located between the two mounting bosses 3. The locking piece 5 extends forward and backward in a natural state. An elastic member 6 is sleeved on the pin 4. The elastic member 6 in this embodiment is a spring, specifically a torsion spring. The two legs at both ends of the torsion spring are respectively against the side wall of the plug housing 1 and the inner wall of the locking piece 5, so that the locking piece 5 maintains the front-to-back extension in a natural state and is in a pre-tightened state.

[0048] The locking piece 5 extends forward and backward and is located outside the guide groove 2. The rear end of the locking piece 5 is plate-shaped, and the edge of the remaining part of the locking piece 5 is vertically bent toward one side of the plug housing, reducing the distance between the locking piece 5 at the plug end and the side wall of the plug housing 1, thereby reducing the space outside the guide groove 2, and preventing the plug from being excessively tilted in the plugging direction when the plug and the socket are plugged in. The vertically bent part at the front end of the locking piece 5 is a clamping wall 503, which is used to clamp on the locking platform of the socket to achieve locking. At the same time, due to the elastic setting of the locking piece 5, when the plug and the socket are plugged together, if the oblique insertion angle of the plug is too large, the guide key on the socket will open the locking piece 5, expand the distance between the locking piece 5 and the guide groove 2, and facilitate the insertion of the guide key between the locking piece and the guide groove. Under the restoring force of the elastic member 6, the distance between the guide groove 2 and the locking piece 5 tends to decrease, which has a guiding effect on the operator's oblique insertion operation. When the locking piece 5 returns to its natural state, the inclination angle between the guide groove and the guide key is reduced to a normal range. Then, as the guide key gradually nests in the guide groove 2, the inclination of the plug 1 gradually returns to normal until the plug and the socket are no longer tilted, and then the correct insertion of the plug and the socket is achieved.

[0049] The rear end of the plug housing 1 is inserted into the shield housing 7. After the plug housing 1 and the shield housing 7 are inserted, screws 8 are used to pass through the plug housing 1 and the shield housing 7 in sequence on the outer wall of the plug housing 1 to fix the two. The head of the screw 8 is located on the side wall of the plug housing 1 where the guide groove is located.

[0050] The screw 8 is located at the rear side of the pin 4, and the rear end of the locking plate 5 is provided with an avoidance hole 501. When the rear end of the locking plate 5 is pressed, the front end of the locking plate 5 is tilted and the rear end is pressed down to achieve unlocking or start locking. The screw 8 passes through the avoidance hole 501 to prevent the screw 8 from affecting the unlocking or locking of the locking plate 5.

[0051] A blocking piece 9 is slidably arranged in the avoidance hole 501, and the shape of the blocking piece 9 is L-shaped. The blocking piece 9 includes two perpendicular side plates. One side plate of the blocking piece 9 is slidably matched with the locking piece 5 toward the inner wall of the plug housing 1, and its extension direction is toward the front end; the other side plate is slidably penetrated into the avoidance hole 501, and the width of the end of the other side plate extending out of the avoidance hole 501 is greater than the width of the avoidance hole 501, so that the blocking piece 9 is stuck in the avoidance hole 501. When plugging in, push the blocking piece 9 forward to prevent it from blocking the avoidance hole 501, so that the rear end of the locking piece 5 can be pressed down smoothly. After the plug and the socket are locked, pull the blocking piece 9 backward to block the avoidance hole, and the blocking piece 9 is squeezed and set between the screw 8 and the rear end of the locking piece 5 under the elastic force of the elastic member 6, so that the position of the blocking piece 9 is fixed. At this time, the avoidance hole 501 has been blocked. If the locking piece 5 is accidentally touched, the rear end of the locking piece 5 will not be pressed down and the front end of the locking piece 5 will not be tilted because the blocking piece 9 blocks the avoidance hole, so that the plug and the socket are stably locked. When unlocking, push the blocking piece 9 forward so that the blocking piece 9 no longer blocks the avoidance hole, so that the rear end of the locking piece 5 can be pressed down to achieve unlocking.

[0052] The outer side wall of the shield housing 7 is provided with an escape groove 701 to provide an escape space for the rear end of the locking piece 5 to be pressed down. The rear end of the locking piece 5 is in a plate shape, which can reduce the overall thickness of the rear end of the locking piece 5 and provide sufficient space for the rear end of the locking piece 5 to be pressed down. The rear end of the locking piece is a press-unlock end 504, and the outer side wall of the press-unlock end 504 is provided with an anti-slip protrusion for easy pressing.

[0053] The vertically bent side walls on both sides of the front end of the locking plate 5 are provided with a stopping boss 502 extending toward the plug housing 1. In a natural state, the stopping boss 502 abuts against the outer wall of the plug housing to prevent the front end of the locking plate 5 from being too close to the side wall of the plug housing under the elastic force of the elastic member 6, thereby preventing the cavity between the locking plate 5 and the guide groove 2 from being too small to allow the guide key to be inserted into the guide groove 2.

[0054] The front end of the locking piece 5 is provided with a clamping wall 503, and the rear end is provided with a press-to-unlock end 504. When force F is applied to the press-to-unlock end 504, the front end of the locking piece 5 is tilted, so that the locking piece 5 is in the unlocked position. When the press-to-unlock end 504 is released, the locking piece 5 returns to the locked position under the action of the elastic member. At this time, the clamping wall 503 is clamped on the locking platform 12 of the socket.

[0055] The front end of the plug housing 1 is provided with an insertion boss 101, in which a contact is inserted, and the insertion boss 101 is used to be inserted into the insertion cavity of the socket housing. The cross-sectional shape of the insertion boss 101 is asymmetric in the length direction to prevent the plug from being inserted into the socket in reverse. In this embodiment, the locking piece 5 extends to the outside of the insertion boss 101.

[0056] The socket diagram is as follows Figures 5 to 8 As shown, the socket includes a socket housing 10, and guide keys 11 are arranged on both sides of the front end of the socket housing 10, and the guide keys 11 protrude from the front end surface of the socket housing 10. The guide key 11 is used to be inserted into the guide slot 2 on the plug housing. In order to facilitate insertion into the guide slot 2, the thickness of the guide key 11 gradually decreases in its protruding direction, and the inner side wall of the guide key 11 is perpendicular to the front end surface, and the outer side wall is inclined. After the guide key 11 is inserted into the guide slot 2, the inner side wall of the guide key 11 can fit the bottom of the guide slot 2, ensuring that the plugging direction of the plug is not inclined.

[0057] The width of the guide key 11 is close to the width of the socket housing, and correspondingly, the width of the guide groove 2 is close to the width of the plug housing. When plugging in, the plugging end of the plug housing is inserted as a whole between the two guide keys 11, which is convenient for the operator to identify. In addition, the width of the guide groove 2 and the guide key 11 is large, so the operator can easily plug the plug in the correct position and direction to avoid tilting.

[0058] The two side walls of the front end of the socket housing 10 are protruded to form locking platforms 12, the thickness of the locking platforms 12 gradually decreases in the protruding direction, and the front side walls of the locking platforms 12 are inclined and the rear side walls are vertical. When the plug is plugged into the socket, the locking piece 5 can be pressed, and the front end of the locking piece 5 is tilted. After the clamping wall 503 of the front end of the locking piece 5 passes over the locking platform 12, the locking piece 5 is released, and the locking piece 5 returns to its natural state. Since the rear side wall of the locking platform 12 is vertical, the clamping wall 503 of the locking piece 5 can be clamped on the locking platform 12.

[0059] An inserting cavity 1001 is provided at the front end of the socket housing 10 . A contact piece is provided in the inserting cavity 1001 . The inserting cavity 1001 matches the outer contour of the inserting boss 101 .

[0060] A mounting boss 13 is provided at the rear end of the socket housing 10 for fixing the socket to a corresponding device by screws.

[0061] The guide key 11, the locking platform 12 and the socket housing 10 on the socket are processed in one piece, which saves processing cost and space and is conducive to miniaturization of the connector.

[0062] In the utility model, at the plug end, the guide locking structure is composed of the guide groove, locking piece, pin, elastic member and other structures, and at the socket end, the guide locking structure is composed of the guide key, locking platform and other structures. When the plug and the socket are plugged in, the contact pieces can be plugged in only when the inner side wall of the guide key 11 and the matching side wall of the guide groove 2 begin to fit tightly. At this time, the plug and the socket are not tilted, and then the plugging boss 101 is inserted into the plugging cavity 1001, thereby preventing oblique insertion and pulling out. Under the elastic force of the elastic member 6, the locking piece 5 is hooked with the locking platform 12 when buckled to achieve locking. When the locking piece 5 is pressed to lift it, the socket can be pulled out smoothly, realizing the separation of the plug and the socket.

[0063] The simulation diagram of the plug and socket to prevent oblique insertion is as follows Fig. 9 , Fig.10 As shown, when plugging in, press the locking piece 5, and the guide key 11 on the socket housing first enters the gap between the locking piece 5 and the plugging boss 101. The gap between the locking piece 5 and the plugging boss 101 is large, which is convenient for the operator to align and plug in. Then the guide key 11 enters the guide groove 2 of the plug housing. At this time, the plugging boss 101 of the plug enters the plugging cavity 1001 of the socket. The guide groove 2 cooperates with the guide key 11 to standardize the relative position relationship between the plug and the socket, so that the plugging end of the plug will not collide with the plugging end face and the jack end face of the socket; continue to plug in, the locking piece 5 of the plug hooks the locking platforms 12 on both sides of the socket to achieve the locking of the product, such as Fig.11 As shown, the blocking piece 9 is then pulled back to block the avoidance hole 501 to prevent accidental contact with the locking piece 5 and unlocking, thereby achieving stable locking. When separating the products, the blocking piece 9 is pushed aside, and the locking piece 5 of the plug is pinched and pulled apart. Before the plug-in boss 101 is separated from the plug-in cavity 1001, the guide key is not separated from the guide groove, so that straight pulling is achieved, and the locking and unlocking method is relatively simple and convenient to operate.

[0064] In the plug and the socket, before the pin contact and the socket contact come into contact, the plug and the socket are already in an aligned vertical state under the restraint of the guide key and the guide groove, so there is no possibility of damage to the contact due to oblique insertion or withdrawal. Under the action of the guide key of the socket and the guide groove of the plug, when the socket and the plug are plugged in or out, the plugging boss 101 is restrained, and can only be plugged in or out straightly, avoiding the phenomenon of oblique insertion or withdrawal, thereby avoiding damage to the plug and the socket.

[0065] The anti-oblique insertion and oblique withdrawal quick lock structure of the utility model can be applied to rectangular connectors with different core numbers and sizes.

[0066] In other embodiments, the front side wall of the locking platform 12 has a larger inclination angle. When plugging in, the locking plate 5 is directly pushed. After the locking plate 5 contacts the front side wall of the locking platform 12, the locking plate 5 is gradually stretched open. When the locking plate 5 passes over the locking platform 12, the front side wall of the locking plate is stuck on the rear side wall of the locking platform 12. During this process, if the oblique insertion angle of the plug is too large, the guide key on the socket will stretch the locking plate 5, expand the distance between the locking plate 5 and the guide groove 2, and facilitate the insertion of the guide key between the locking plate and the guide groove. Under the action of the restoring force of the elastic member 6, the distance between the guide groove 2 and the locking plate 5 tends to decrease, which has a guiding effect on the operator's oblique insertion operation.

[0067] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
