Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of connectors, in particular to a plug and a connector. Background Art
[0002] The connector includes a plug and a socket. There are many existing locking structures for plugs and sockets. The scheme of using a sliding structure to achieve locking is as follows Figures 7 to 9 shown.
[0003] The plug comprises a plug housing 1, a handle 2 rotatably arranged on the plug housing 1, a lock 21 arranged on the handle 2 and a hanging platform 11 arranged on the plug housing 1 to lock the lock 3. A limited sliding groove 22 is arranged on the handle 2.
[0004] The socket includes a socket housing 31 and a locking post 32 disposed on the socket housing 31 .
[0005] With the above structure, first rotate the handle 2 to Figure 7 When the plug and the socket are plugged in, the locking column 32 slides into the limiting slide groove 22, and the handle is pulled to rotate in the direction of the hanging table 11. After the plug is completed, the locking column 32 slides to the end of the limiting slide groove 22, and the handle 2 is in a horizontal position, such as Fig. 9 By engaging the lock buckle 21 with the hanging platform 11, the plug and the socket can be locked in the plug-in state, which can ensure that the plug and the socket will not be disconnected during vibration and impact.
[0006] However, the above structure has the following problems:
[0007] The limiting slide groove 22 realizes the movement limit of the socket relative to the plug. Therefore, when designing, it is necessary to strictly calculate the sliding stroke of the plug and the socket to determine the length of the limiting slide groove 22. If there is a calculation error, it will lead to unreliable locking and disconnection. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0033] The utility model provides a plug and a connector. The connector comprises the plug and a socket matching the plug.
[0034] like Figures 1 to 6 As shown, the plug includes a plug housing 1 and a handle assembly. The end of the plug housing 1 for inserting into a socket is the socket insertion end, and a first locking structure 13 is provided on the plug housing 1; the handle assembly includes a handle 2 rotatably connected to the socket insertion end of the plug housing 1 and a gear structure 4 coaxially rotating with the handle 2, and the gear structure 4 is placed between the handle 2 and the plug housing 1.
[0035] Correspondingly, such as Figure 3 As shown, the socket comprises a socket housing 31, a rack structure 34 arranged on the socket housing 31, and a moving guide and limiting structure for moving and guiding the rack structure 34. The gear structure 4 is meshed with the rack structure 34.
[0036] The socket housing 31 is provided with a mounting hole 311 for mounting a wire assembly, wherein the number of wire assemblies is set according to the requirements of the connector. The rack structure 34 is arranged parallel to the axial direction of the mounting hole 311, so that when the gear structure drives the rack structure 34 to move under the guiding and limiting action of the moving guide and limiting structure, it can only move along the axial direction of the mounting hole 311.
[0037] With the above structure, when plugging in, the rack structure 34 meshes with the gear structure, and the handle is turned to control the gear structure to rotate, thereby driving the socket to be inserted and locking the socket, and then fixing the second locking structure 23 and the first locking structure 13. With this structure, since the gear rack is used for moving drive and locking, the locking reliability will not be affected by the design accuracy, and the connection stability of the connector is improved.
[0038] The movable guide limiting structure can be directly arranged on the rack structure 34, or directly fixed on the socket housing 31. Figure 3 As shown, in order to enhance the structural stability, the movable guide limiting structure is fixed to the socket housing 31 while connecting the rack structures 34 on both sides of the mounting hole 311 .
[0039] In order to improve the stability of the connector plugging, there are two rack structures 34 which are respectively arranged on both sides of the mounting hole 311 . Correspondingly, there are also two gear structures which are respectively arranged on both sides of the plug housing 1 .
[0040] Generally, for the convenience of fixing, a fixing flange 35 is provided on the socket housing 31. Screw holes are provided on the fixing flange 35 to facilitate the installation of bolts.
[0041] The second locking structure 23 and the first locking structure 13 realize the fixation of the handle and the plug housing 1, and there are many ways to achieve this, for example, fixing with bolts, or using the existing hanging platform and lock buckle structure, or using the existing Figure 2 , 4 The structure shown. Figure 2 , 4 As shown, the first locking structure 13 is a locking hole, and the second locking structure 23 is a sliding member. A locking tongue that can be clamped in the locking hole is provided on the sliding member. A sliding groove structure is provided on the handle 2. The sliding member is placed in the sliding groove and moved, so that the locking tongue can be controlled to be disengaged from the locking hole or placed in the locking hole, thereby realizing unlocking and locking of the handle respectively.
[0042] On the basis of any of the above structures, in order to achieve the stability of the movement of the socket during insertion and improve the reliability of the connector connection, a guide structure 14 for guiding and limiting the movement of the socket is provided on the plug housing 1. Figure 2 As shown, the guide structure 14 is a guide groove. Correspondingly, the movable guide plate 33 on the socket is placed in the guide groove. After the movable guide plate is placed in the guide groove, under the action of the guide groove, it is only allowed to move along the axial direction of the plug housing.
[0043] Since the length of the insertion end of the socket is relatively small when it is plugged in, the gear structure 4 does not need to be a full-tooth structure, that is, it does not need to be a gear with all teeth in the circumferential direction, such as Figure 6 As shown, only teeth corresponding to the process amount need to be machined on the disc. The handle 2 rotates coaxially with the gear structure 4, and the gear structure 4 can be directly fixed on the rotating shaft of the handle, or a structure as shown in 6 can be adopted, in which the gear structure 4 is directly integrally formed with the handle. The integrally formed structure is easy to install and fix.
[0044] On the basis of any of the above structures, in order to prevent the handle from rotating to the axis perpendicular to the plug housing and rotating arbitrarily when not plugged into the socket, a relevant limit structure can be set on the handle assembly and the plug housing. When plugged into the socket, the handle should be kept in a suitable position so that the socket can be properly plugged into place when the handle is rotated to fit the plug housing. For this purpose, the limit structure includes two directions of limit. The first direction is to limit the rotation of the handle away from the plug housing 1 socket insertion end, such as Figure 1The state shown is the limit of the handle rotating counterclockwise; the second is the limit of the rotation toward the socket insertion end of the plug housing 1, such as Figure 1 The state shown is the limit of the clockwise rotation of the handle.
[0045] In this regard, for limiting the first direction, a first limiting structure 15 is provided on the plug housing 1, and a second limiting structure 41 is provided on the handle assembly to cooperate with the first limiting structure 15 so as to limit the rotation of the handle assembly when the movable end of the handle 2 is rotated to the socket insertion end.
[0046] The first limiting structure 15 and the second limiting structure 41 can be implemented using a variety of structures.
[0047] Example 1: The first limiting structure 15 and the second limiting structure 41 are both fixing holes, the two fixing holes are located in corresponding positions, and limiting is achieved by inserting a pin shaft.
[0048] Example 2: Figure 2 , 6 As shown, the first limiting structure 15 is a protruding structure, and the second limiting structure 41 is a convex strip arranged on the gear structure 4. Since the gear structure 4 is not full of teeth, the convex strip is arranged at a position avoiding the teeth. The convex strip is an elastic convex strip, and the thickness of the convex structure is slightly greater than the distance between the plug housing and the convex strip. With this structure, during the plugging process, only a little force needs to be applied to the handle to deform the convex strip and break away from the limiting effect of the convex structure on it.
[0049] For the limitation in the second direction, a third limiting structure 16 is directly provided on the plug housing 1 to limit the rotation amount of the handle 2 toward the socket insertion end. Figure 1 , 2 , the limiting protrusion can be directly processed on the plug housing 1.
[0050] With the above structure, before plugging the socket, turn the plug handle to a vertical position. Figure 1 As shown, at this time, the handle maintains this state under the action of the limit structure. For the plug socket, the rack structure 34 on the socket is engaged with the teeth of the gear structure. At this time, the handle is rotated counterclockwise to drive the gear structure to rotate, and then the rack structure 34 is driven to move until the operating end of the handle rotates to fit with the plug housing. At this time, the socket and the plug are connected, and the first locking structure 13 and the second locking structure 23 are locked.
[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
