Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more specifically, to a connector with a linkage unlocking structure. Background Art

[0002] In a high-voltage connector, in order to assist the connection between the plug and the socket and ensure a stable connection, a rotatable handle is usually provided on the plug, a gear structure is provided on the handle, and a rack structure extending along the insertion direction is provided on the socket. Thus, when the plug and the socket are connected, the handle is rotated from the pre-installed position to the locked position, and during this period, the gear structure is driven to engage with the rack structure to promote the stable connection between the plug and the socket.

[0003] In some prior arts, the handle is locked in the pre-installed position through a buckle structure. For example, an elastic arm is provided on the inner side of the handle, and a groove is provided on the outer side of the plug housing. When the handle is in the pre-installed position, the free end of the elastic arm is snapped into the groove to lock the handle. However, when using this structure, a certain force needs to be applied to the handle to force the elastic arm to leave the groove, thereby forcing the handle to leave the pre-installed position, and the operation is relatively inconvenient, and the application effect is not ideal. Summary of the Utility Model

[0004] The utility model provides a connector with a linkage unlocking structure to solve the problem of inconvenient operation in the prior art.

[0005] A connector with a linkage unlocking structure provided by the utility model includes a plug and a socket adapted for insertion. A handle is rotatably provided on the plug, a first tooth part is provided on the handle, and a second tooth part meshing with the first tooth part is provided on the socket. Rotating the handle can drive the plug and the socket to move relatively along the insertion direction. The handle has a pre-installed position and a locking position on the plug. A positioning part is provided on the handle, and an elastic hook is formed on the outer wall of the plug on one side of the handle. When the handle is in the pre-installed position, the elastic hook is engaged with the positioning part to position the handle in the pre-installed position. An unlocking part is provided on the elastic hook. When the plug and the socket are inserted, the unlocking part interferes with the end of the socket facing the plug. When the plug and the socket are inserted, the end of the socket facing the plug pushes the unlocking part to lift the free end of the elastic hook, thereby realizing the separation of the elastic hook and the positioning part.

[0006] Optionally, a retaining ring is circumferentially provided on the outer side of the end of the plug facing the socket. One end of the elastic hook is connected to the retaining ring, and the other end extends along the direction in which the plug withdraws from the socket. A gap is provided between the elastic hook and the outer wall of the plug. When the plug and the socket are inserted, a part of the end of the socket facing the plug enters the gap between the elastic hook and the plug and pushes the unlocking part to lift the free end of the elastic hook, thereby realizing the separation of the elastic hook and the positioning part.

[0007] Optionally, an unlocking portion and a hook portion that is engaged and cooperated with the positioning portion are provided on one end face of the elastic hook facing the plug, and the unlocking portion and the hook portion are sequentially arranged along the direction in which the plug withdraws from the socket.

[0008] Optionally, when the socket pushes against the unlocking portion to separate the hook portion from the positioning portion, the first tooth portion and the second tooth portion start to mesh.

[0009] Optionally, both the unlocking portion and the hook portion are protruding structures protruding from the end face of the elastic hook.

[0010] Optionally, a receiving groove is provided on the outer wall of one end of the socket facing the plug. After the elastic hook is separated from the positioning portion, when the handle is rotated to make the plug and the socket continue to move towards each other until the plug and the socket are plugged in, the unlocking portion and the hook portion are jointly received in the receiving groove.

[0011] Optionally, at least the groove wall at one end of the receiving groove close to the plug is a bevel structure to facilitate the hook portion and the unlocking portion to withdraw from the receiving groove when the plug withdraws from the socket.

[0012] Optionally, the positioning portion is a cantilever structure located in front of the first tooth portion in the rotation direction of the handle. There is a mutually cooperating bevel between the hook portion and the positioning portion, and a predetermined angle of 80° - 85° is provided between the bevel provided on the hook portion and the plugging direction of the connector.

[0013] Optionally, both the elastic hook and the retaining ring are integrally formed on the plug.

[0014] Optionally, a buckle portion is further provided on the handle, and a clamping platform is provided on the outer wall of the plug at the rotation path of the buckle portion. When the handle is in the locked position, the buckle portion is engaged and cooperated with the clamping platform to position the handle in the locked position.

[0015] The utility model has the following beneficial effects:

[0016] The utility model can position the handle at the pre-installed position through the elastic hook and the positioning portion. When the plug is plugged into the socket, the socket can release the positioning portion of the elastic hook by pushing against the unlocking portion on the elastic hook, without the need for an operator to provide an external force to force the handle to leave the pre-installed position. Therefore, the handle in the pre-installed position can be self-unlocked when the plug and the socket are plugged in, and the operation is convenient.

[0032] Now, various exemplary embodiments of the present utility model will be described in detail with reference to the accompanying drawings. It should be noted that: Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present utility model.

[0033] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present utility model or its application or use.

[0034] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said techniques, methods, and devices should be regarded as part of the specification.

[0035] In all examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0036] As Figures 1-9 shown, an embodiment of the present utility model provides a connector with a linkage unlocking structure, including a plug 1 and a socket 3 that are adaptively plugged. A handle 2 is rotatably provided on the plug 1. A first tooth portion 21 is provided on the handle 2. A second tooth portion 32 that meshes with the first tooth portion 21 is provided on the socket 3. Rotating the handle 2 can drive the plug 1 and the socket 3 to move relative to each other along the plugging direction. The handle 2 has a pre-installed position and a locking position on the plug 1.

[0037] A positioning portion 22 is provided on the handle 2. An elastic hook 13 is formed on the outer wall of the plug 1 on one side of the handle 2. When the handle 2 is in the pre-installed position, the elastic hook 13 is engaged with the positioning portion 22 to position the handle 2 in the pre-installed position.

[0038] An unlocking portion 132 is provided on the elastic hook 13. The unlocking portion 132 interferes with the end of the socket 3 facing the plug 1 when the plug 1 and the socket 3 are plugged. When the plug 1 and the socket 3 are plugged, the end of the socket 3 facing the plug 1 pushes against the unlocking portion 132 to lift the free end of the elastic hook 13, thereby realizing the separation of the elastic hook 13 from the positioning portion 22.

[0039] In the above solution, the handle 2 can be positioned in the pre-installed position through the elastic hook 13 and the positioning portion 22. When the plug 1 and the socket 3 are plugged, the socket 3 can release the positioning portion 22 by pushing against the unlocking portion 132 on the elastic hook 13, without the need for an operator to apply an external force to force the handle 2 to leave the pre-installed position. Therefore, the handle 2 can be self-unlocked when the plug 1 and the socket 3 are plugged, which is convenient for operation.

[0040] Further, in order to facilitate the setting of the elastic hook 13 and facilitate the socket 3 to push against the unlocking portion 132 on the elastic hook 13, as Figure 1 、 3, as shown in Figures 4 and 7, in this embodiment, a retaining ring 11 is disposed around the outer side of one end of the plug 1 facing the socket 3. One end of the elastic hook 13 is connected to the retaining ring 11, and the other end extends along the direction in which the plug 1 withdraws from the socket 3. There is a gap between the elastic hook 13 and the outer wall of the plug 1. When the plug 1 is inserted into the socket 3, a part of the end of the socket 3 facing the plug 1 enters the gap between the elastic hook 13 and the plug 1 and pushes against the unlocking portion 132 to lift the free end of the elastic hook 13, thereby realizing the separation of the elastic hook 13 from the positioning portion 22.

[0041] As Figure 5 , 7 , as shown in Figures 7 and 9, in this embodiment, a retaining wall 31 extending towards the plug 1 is integrally formed on the socket 3. When the plug 1 is inserted into the socket 3, in fact, the retaining wall 31 of the socket 3 enters the inner side of the retaining ring 11, and the corresponding part of the retaining wall 31 enters the gap between the elastic hook 13 and the plug 1.

[0042] Further, considering factors such as the insertion direction, smooth unlocking, simple, effective and reasonable structural design, as Figure 4 shown, in this embodiment, an unlocking portion 132 and a hook portion 131 that is engaged with the positioning portion 22 in a snap-fit manner are provided on the end face of the elastic hook 13 facing the plug 1, and the unlocking portion 132 and the hook portion 131 are arranged in sequence along the direction in which the plug 1 withdraws from the socket 3; more specifically, as a simple, reasonable and easy-to-process structure, both the unlocking portion 132 and the hook portion 131 are protruding structures protruding from the end face of the elastic hook 13. In order to facilitate demolding during injection molding, two hook portions 131 are arranged side by side, and one unlocking portion 132 is provided and corresponds to the gap between the two hook portions 131 in the insertion direction.

[0043] Further, in order to enable the handle 2 to immediately assist in the insertion of the plug 1 into the socket 3 after the handle 2 is disengaged from the pre-installed position and to prevent the ineffective rotation of the handle 2, in this embodiment, when the socket 3 pushes against the unlocking portion 132 to separate the hook portion 131 from the positioning portion 22, the first tooth portion 21 and the second tooth portion 32 start to engage.

[0044] Further, in order to enable the elastic hook 13 to return after the plug 1 and the socket 3 are inserted in place, and to prevent the elastic hook 13 from protruding and affecting the appearance and other adjacent parts at the installation location, as Figure 5 , 7 , as shown in Figures 7 and 9, in this embodiment, a receiving groove 33 is provided on the outer wall of one end of the socket 3 facing the plug 1. After the elastic hook 13 is separated from the positioning portion 22, when the handle 2 is rotated to move the plug 1 and the socket 3 towards each other until the plug 1 and the socket 3 are completely inserted, the unlocking portion 132 and the hook portion 131 are jointly received in the receiving groove 33. The receiving groove 33 is actually located on the side wall of the above-mentioned retaining wall 31.

[0045] In this embodiment, in order to make the positioning of the handle 2 more stable, elastic hooks 13 are formed on the outer wall of the plug 1 at positions corresponding to both sides of the handle 2. Two positioning portions 22 are correspondingly provided on the handle 2, and two accommodating grooves 33 are also correspondingly provided on the socket 3.

[0046] Further, as shown in Figure 7 , 9 In this embodiment, at least the groove wall at one end of the accommodating groove 33 close to the plug 1 is a slope structure 331, so as to facilitate the hook portion 131 and the unlocking portion 132 to exit the accommodating groove 33 when the plug 1 is withdrawn from the socket 3.

[0047] Further, as a simple, reasonable and easy-to-process structure, as shown in Figure 2 , 4 In this embodiment, the positioning portion 22 is a cantilever structure located in front of the first tooth portion 21 in the rotation direction of the handle 2. In order to make the cooperation between the hook portion 131 and the positioning portion 22 more stable and prevent the hook portion 131 and the positioning portion 22 from being easily disengaged when the unlocking portion 132 is not pushed, there are mutually cooperating slopes between the hook portion 131 and the positioning portion 22, and the slope provided on the hook portion 131 has a predetermined angle of 80°-85° with the insertion direction of the connector. The specific predetermined angle α in this embodiment is 82.5°. When the retaining wall 31 of the socket 3 pushes the unlocking portion 132 to rotate the free end of the elastic hook 13 and drive the hook portion 131 to rotate, the predetermined angle within the above range can also ensure the smooth separation of the slopes between the hook portion 131 and the positioning portion 22, so that the hook portion 131 and the positioning portion 22 can be separated smoothly.

[0048] Further, for the convenience of processing and manufacturing, in this embodiment, the elastic hook 13 and the retaining ring 11 are integrally formed on the plug 1.

[0049] Further, in order to position the handle 2 in the locked position, as shown in Figure 1 , 2 , 6, 8, in this embodiment, the handle 2 is further provided with a buckle portion 23, and a boss 12 is provided on the outer wall of the plug 1 at the rotation path of the buckle portion 23. When the handle 2 is in the locked position, the buckle portion 23 is engaged with the boss 12 to position the handle 2 in the locked position.

[0050] During specific use, when the plug 1 and the socket 3 are separated from each other, as shown in Figure 1 , the handle 2 on the plug 1 is rotated to the pre-installed position. At this time, the positioning portion 22 on the handle 2 is engaged with the hook portion 131 of the elastic hook 13, thereby preventing the handle 2 from rotating towards the locked position, and the handle 2 is held in the pre-installed position; when the plug 1 and the socket 3 are inserted, as shown in Figure 6 , 7As shown, the enclosure 31 of the socket 3 enters the inner side of the retaining ring 11 of the plug 1. The part of the enclosure 31 corresponding to the elastic hook 13 enters the gap between the elastic hook 13 and the plug 1, and pushes against the unlocking part 132 to lift the free end of the elastic hook 13, thereby disengaging the positioning part 22 from the engagement with the hook part 131, realizing the automatic release of the handle 2 from the pre-assembled position. At this time, the handle 2 can be manually rotated. At the same time, the part of the enclosure 31 corresponding to the elastic hook 13 can also push against the positioning part 22 to assist in rotating the handle 2, so as to promote the continuous engagement of the first tooth part 21 and the second tooth part 32 to assist in the insertion of the plug 1 into the socket 3; when the plug 1 is inserted into the socket 3 in place, as Figure 8 and 9 shown, the hook part 131 and the unlocking part 132 of the elastic hook 13 are both received in the receiving groove 33 on the side wall of the enclosure 31. The elastic hook 13 elastically returns to its original state. At this time, the handle 2 is rotated to the locked position, and the buckle part 23 is engaged with the clamping platform 12 to position the handle 2 in the locked position; when disassembling the plug 1 and the socket 3, the above steps can be referred to, and the reverse operation and movement can be carried out.

[0051] Although some specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration and not for limiting the scope of the present invention. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
