The locking piece is matched with the locking buckle 11 and used as a first heavy locking structure to realize anti-falling locking between the connector and the adaptive connector 8.
The end part of the second extension part 7 of the first locking part is bent into a convex part which is exposed through the second edge side 32 of the flat box-shaped shell 1 and is used as an operation part of the locking part for pressing operation by an operator to push the first locking part 3 to rotate from the locking position to the unlocking position around the rotation axis, the second locking part 28 is linked with the first locking part 3 through the second extension part 31 of the second locking part, and when the first locking part 3 rotates to the unlocking position, the second locking part 28 also rotates to the unlocking position to realize unlocking with the adapter connector 8. In the present embodiment, in order to keep a large distance between the operation portion of the lock member and the lead wires and prevent the operator from accidentally touching the lead wires when performing the unlocking operation, the first edge side 25 and the second edge side 32 are opposite edge sides of the flat box-shaped housing 1. In other embodiments, the back side surface of the locking hook may not be an arc surface, when the connector is plugged, the operating part is pressed by hand to enable the locking part to be in the unlocking position, after the connector is plugged in place, the operating part is released, and the locking hook and the locking buckle are locked and matched under the action of the elastic resetting part. In other embodiments, a locking member may be provided on only one of the two housings, provided that only one locking member is engaged with the locking catch to ensure that the connector can be stably inserted into the mating connector without being accidentally disengaged. As shown in fig. 3 and 4, in addition, a first wire passing groove 33 is formed in the first housing 4, a second wire passing groove 34 is formed in the second housing 5, and after the first housing 4 and the second housing 5 are buckled, the first wire passing groove 33 and the second wire passing groove 34 surround a wire passing hole.
In order to prevent the locking member 3 from being unlocked by accidental rotation, the connector is further provided with a restricting member 12, and the structure of the restricting member 12 is as shown in fig. 6 and 7, and includes an operating end 13, a connecting plate 14, a restricting shutter 15, and an elastic catch 16. The operation end 13 and the connecting plate 14 are connected through a connecting arm 17 to form an I shape, and the limiting baffle 15 and the elastic buckle 16 are positioned on the end surface of the connecting plate 14, which is back to the operation end 13, and are arranged in parallel along the thickness direction of the flat box-shaped shell 1.
In order to mount the limiting component 12, as shown in fig. 3 and 4, through grooves penetrating along the wall thickness direction of the housing are formed in the side faces of the corresponding edges of the first housing 4 and the second housing 5, the through groove on the first housing 4 is a first through groove 35, the through groove on the second housing 5 is a second through groove 36, the opening directions of the two through grooves face the buckling direction of the two housings and are used for avoiding the connecting arm 17, after the first housing and the second housing are buckled, the through grooves on the two housings enclose an avoiding hole 37, the limiting component 12 partially exposes out of the flat box-shaped shell from the avoiding hole 37, and the limiting component forms the operation end 12 of the limiting component 12. The edge sides of the first shell 4 and the second shell 5, which are provided with the through slots, form the edge side of the flat box-shaped shell 1 between the first edge side and the second edge side. The edge side face and the edge side face of the contact member, which is used for being plugged with the mating connector and whose one end is exposed from the flat box-shaped housing 1, are opposite faces.
In other embodiments, the operation end of the restriction member may be exposed through the second edge side of the flat box-shaped case, and correspondingly, a through groove may be formed in the edge side of the second edge side of the first and second cases constituting the flat box-shaped case. Of course, the through groove may be formed only on the edge side surface of one of the first housing and the second housing, and the edge side surface of the other housing is blocked from the opening of the through groove by the engagement of the two housings, so as to restrict the movement stroke of the restriction member in the thickness direction of the flat box-shaped housing.
The operation end 13 is used for the force application operation of the operator, and the operator pushes the operation end 13 to enable the limiting component 12 to move along the thickness direction of the flat box-shaped shell 1, as shown in fig. 6, for the force application of the operator, the surface of the operation end 13 for the operator to press is made into a non-smooth surface. The moving stroke of the limiting part 12 is restrained by the stop matching of the groove bottom of the through groove and the connecting arm 17. Along the thickness direction of the flat box-shaped shell 1, the size of the connecting plate 14 is larger than that of the operating end 13 and larger than that of the avoiding hole 37 along the direction, so that the connecting plate 14 plays a role in blocking the avoiding hole 37 and prevents dust from entering the flat box-shaped shell 1 through the avoiding hole.
In order to ensure that the limiting component 12 can slide smoothly, as shown in fig. 6 and 7, the end surface of the connecting plate 14 facing the operation end 13 is further integrally formed with a convex rib 18 on both sides of the connecting arm 17, the length of the convex rib 18 extends along the thickness direction of the flat box-shaped housing 1, correspondingly, the hole of the avoiding hole 37 is provided with an overhanging portion 22 extending between the operation end and the connecting plate 14, the side of the overhanging portion 22 facing the connecting plate 14 is provided with a sliding groove matched with the convex rib 18, and the limiting component 12 is installed on the flat box-shaped housing 1 in a guiding manner along the thickness direction of the flat box-shaped housing 1 by matching the sliding groove with the convex rib 18. The convex ribs and the sliding grooves are used as guide structures, so that the limiting component is installed on the flat box-shaped shell in a guiding and matching mode along the thickness direction of the flat box-shaped shell 1.
During assembly, the limiting component 12 is matched and inserted with the suspension part 22 on the first shell 4 or the second shell 5 along the direction of the flat box-shaped shell 1, and then the two shells are buckled and fixed. In other embodiments, the rib may also be provided on an end surface of the operating end facing the connecting plate, correspondingly, the sliding groove is provided on an end surface of the overhanging portion facing the operating end. It is also possible to arrange one rib on the operating end and one on the connecting plate. The guide structure may also be a protrusion disposed on the end surface of the connection plate facing the operation end, and the protrusion and the hole of the avoidance hole are in blocking fit in a direction perpendicular to the thickness of the flat box-shaped casing. Of course, the connection arm and the hole of the avoidance hole can be directly matched in a blocking mode along the direction perpendicular to the thickness of the flat box-shaped shell.
The limiting member 12 has a stop position and an avoidance position on the moving stroke, and in the present embodiment, the limiting member 12 is at the bottom position of the second through groove 36 as the stop position, and at the bottom position of the first through groove 35 as the avoidance position. As shown in fig. 3 and 9, when the limiting member 12 is in the stop position, the limiting member is in stop engagement with the end 23 of the second overhang portion 7 of the locking member 3 through the limiting baffle 15, and at this time, the operator cannot push the operation portion of the locking member 3, thereby preventing the connector from being unlocked by mistake.
When the connector is unlocked, as shown in fig. 8 and 10, the restricting member 12 is slid to the escape position, the restricting shutter 15 avoids the end 23 of the second overhang 7, and the operator can press the operating portion of the lock member 3 to rotate the lock member 3 to the unlock position, thereby releasing the lock between the connector and the mating connector 8. The restricting member 12 serves as a second re-locking structure for locking and restricting the movement of the locking member 3.
Because the limiting part 12 moves 1 along the thickness direction of the flat box-shaped shell 1, during unlocking operation, an operator can press the bottom surface of the first shell 4, which is back to the second shell 5, with one finger as a force application point, and the other finger pulls the operating end 13 to unlock the limiting part 12, in the process, the finger of the operator cannot be close to the outgoing line, so that the operator cannot mistakenly touch the outgoing line to cause operation violation.
In order to enable the limiting component 12 to be stably positioned at the stop position or the avoidance position after the position adjustment, as shown in fig. 8, a locking block 19 is further installed in the first housing 4, the locking block 19 is provided with two locking grooves 20 which are arranged in parallel along the thickness direction of the flat box-shaped housing, correspondingly, the elastic buckle 16 is provided with a locking protrusion 24 which is matched with the locking grooves 20, and the locking protrusion 24 locks the limiting component 12 at the stop position or the avoidance position by being locked in different locking grooves 20. When the limiting component 12 is moved, the elastic force of the elastic buckle 16 needs to be overcome to deform the limiting component, so that the clamping protrusion 24 can slide from one clamping groove 20 to the other clamping groove 20, and the position of the limiting component 12 is changed between the stopping position and the avoiding position. In other embodiments, the locking piece may be integrally formed with the first housing. The elastic buckle can also be a reed arranged on the end face of the operation end facing the connecting plate, the reed stretches towards the connecting plate and is matched with the clamping groove to lock the position of the limiting part.
When the locking protrusion 24 slides from one card slot 20 to the other card slot 20, a click sound can be emitted, and when the operator cannot directly observe the limiting component 12 due to the fact that the connector is shielded by other components, whether the limiting component 3 moves to the target position can be judged through the click sound.
In addition, in order to further improve the stability and reliability of the locking connection of the connector, in the present embodiment, the end surface of the locking member 3 that engages with the limiting member 12 is an inclined surface that is inclined toward the first housing 4, and when the connector is subjected to a shock impact so that the locking member 3 rotates toward the unlocking position, the locking member 3 has a component force toward the second housing 5 by a thrust force that is applied to the limiting member 12 by the inclined surface, and the component force causes the limiting member 12 to be stably held in the blocking position.
Based on the fact that the size of the connecting plate 14 in the thickness direction of the flat box-shaped shell 1 is larger than that of the operating end 13, in order to facilitate visual and quick confirmation of whether the limiting component 12 is in the stopping position by a maintainer, the part, close to the second shell 5, of the plate surface of the connecting plate 14 facing the operating end 13 and the edge of the through groove of the second shell 5 are painted red as marks, when the limiting component is in the stopping position, the marks on the connecting plate 14 are located in the flat box-shaped shell 1 and cannot be seen, meanwhile, the operating end 13 blocks the marks on the second shell 5, that is, if the red marks cannot be seen, the limiting component 12 is in the stopping position, otherwise, if the marks are seen in the routing inspection process, the limiting component 12 of the connector is not in the stopping position, and at this time, the limiting component 12 needs to be shifted to the stopping position. In other embodiments, it is also possible to provide a mark on the connecting plate at a portion of the plate surface of the connecting plate 14 toward the operating end 13 near the first housing 4, and the mark can be viewed when the restricting member is in the position to stop the locking member.
The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention, the scope of the present invention is defined by the appended claims, and all structural changes that can be made by using the contents of the description and the drawings of the present invention are intended to be embraced therein.
