[0002] A connector is an electrical and electronic device used to establish a temporary or permanent electrical connection between circuits. It enables the current or signal between devices to be transmitted smoothly and efficiently. Connectors usually consist of a plug and a socket, and the connection between the two parts is achieved by insertion or docking.

[0003] At the same time, in order to prevent the connector from accidentally disconnecting or falling off, a corresponding locking structure needs to be designed to ensure that the connector can maintain a stable and continuous contact state after connection, avoiding connection failure due to vibration, pulling or other external forces.

DETAILED DESCRIPTION

[0040] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0041] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, device, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0042] In one embodiment of the present invention, a connection structure is provided, such as Figures 1 to 5 As shown, the connection structure includes a first connector 1, a locking component 2 and a second connector 3. The second connector 3 is connected to the first connector 1, the locking component 2 is sleeved on the outside of the first connector 1 and the second connector 3 and is connected to the first connector 1 and the second connector 3 respectively, and the relative position of the first connector 1 and the second connector 3 is locked or unlocked by the locking component 2.

[0043] Specifically, the first connector 1 and the locking component 2 are connected by threads, and a first locking structure is provided between the first connector 1 and the locking component 2, and the first locking structure is configured with a locked state and an unlocked state. When the first locking structure is configured in the locked state, the axial and / or radial relative positions of the first connector 1 and the locking component 2 are locked; when the first locking structure is configured in the unlocked state, the first connector 1 and the locking component 2 are separable. The connection structure provided by the utility model is that the first connector 1 and the locking component 2 are connected by threads, and the axial and / or radial relative positions of the two are locked by the first locking structure, which can prevent the two from being unlocked due to misoperation, or the connection from being loosened due to vibration or shaking. A second locking structure is provided between the locking component 2 and the second connector 3, and the second locking structure is configured to lock the second connector 3 relative to the locking component 2 in a direction away from the first connector 1.

[0044] See also Figure 3 and Figure 5 The second locking structure includes a boss 31 disposed on the outer wall of the second connector 3 and a clamping platform 22 disposed inside the locking component 2. Preferably, the boss 31 is a circular ring structure extending outward from the outer wall of the second connector 3. The clamping platform 22 is a circular ring structure extending from the inner wall of the locking component 2 toward the center of the locking component 2.

[0045] like Figure 5 The lower end of the second connector 3 shown in the figure passes through the first end face 23 and the second end face 24 of the locking component 2 in sequence until the boss 31 abuts against the clamping platform 22. Specifically, the first surface of the boss 31 abuts against the second surface of the clamping platform 22, the first surface is the surface of the boss 31 away from the first end face 23 and the first connector 1, and the second surface is the surface of the locking component 2 close to the second locking component 21. As a result, the locking component 2 and the second connector 3 can rotate relative to each other around their axial direction, but the second connector 3 is not rotated relative to the locking component 2 along the axis shown in the figure. Figure 3 and Figure 5 The axial downward direction shown in FIG.

[0046] In one embodiment of the present invention, a housing 4 is further included, and an end of the second connector 3 away from the first connector 1 extends into the interior of the housing 4 and is connected to the housing 4. Figure 5 As shown, the second connector 3 is provided with an external thread 32; Figure 6As shown, an internal thread 41 is provided on the inner wall of the housing 4 , and the internal thread 41 and the external thread 32 are matched and connected to achieve a fixed connection between the housing 4 and the second connector 3 .

[0047] like Figure 4 The lower end of the first connector 1 shown in the figure passes through the first end face 23 of the locking component 2 and is connected to the second connector 3. The locking component 2 is sleeved on the outside of the first connector 1 and is configured to be able to rotate around its axial direction relative to the first connector 1. The relative position locking between the two is achieved by threaded connection and the first locking structure. Since the position of the second connector 3 relative to the locking component 2 in the direction away from the first connector 1 is also locked, the relative position of the first connector 1 and the second connector 3 is locked.

[0048] See also Figures 1 to 4 The first locking structure includes a first locking component 11 arranged on the outside of the first connector 1 and a second locking component 21 arranged on the locking component 2. The first locking component 11 has an elastic component that can move in the radial direction of the first connector 1. Specifically, the first locking component 11 includes a fixed end 111, a free end 112 and a connecting portion 113. The fixed end 111 is fixedly arranged on the outer wall of the first connector 1. The free end 112 constitutes the elastic component, which is configured to be able to move in the radial direction of the first connector 1 and has a protruding portion extending outward. One end of the connecting portion 113 is connected to the fixed end 111, and the other end is connected to the free end 112. The fixed end 111, the connecting portion 113 and the free end 112 are arranged circumferentially along the outer wall of the first connector 1. Correspondingly, a groove 12 is arranged on the outer wall of the first connector 1. The position of the groove corresponds to the position of the free end 112, and it is configured to accommodate the free end 112. That is, the free end 112 is suspended in the free state, and can move toward the groove 12 under pressure.

[0049] The second locking member 21 includes a receiving groove 211, and the receiving groove 211 is configured to receive the protrusion. Figure 3As shown, the receiving groove 211 is preferably a through hole structure, and the shape of the through hole is preferably consistent with the root shape of the protrusion. Preferably, the second locking component 21 also includes a guide surface 212, which is arranged on one side of the receiving groove 211 and arranged along the circumference of the locking component 2, and the distance between the guide surface 212 and the central axis of the locking component 2 increases in the direction close to the receiving groove 211. The guide surface 212 enables the protrusion to slide smoothly into the receiving groove 211 when the first locking mechanism is locked; and the protrusion can slide smoothly out of the receiving groove 211 when the first locking mechanism is unlocked. The first locking structure is one or more. If the first locking structure is multiple, preferably multiple first locking components 11 are evenly distributed on a virtual circumference with the axis of the first connector 1 as the central axis, and the second locking components 21 are arranged one-to-one with the first locking components 11. Alternatively, the first locking component includes one first locking component 11 and one or more second locking components 21. The number of the first locking component 11 is preferably one, and one or two second locking components 21 are correspondingly provided. Figure 3 and Figure 4 In the illustrated embodiment, there is one first locking component 11, which is distributed on a virtual circle with the axis of the first connector 1 as the central axis, and two second locking components 21 are arranged in a circumferential manner on the locking component 2, and any second locking component 21 is used to lock a free end 112 of the first locking component 11. The arrangement of one first locking component 11 and a plurality of second locking components 21 can more conveniently perform locking and unlocking operations on the first connector 1 and the locking component 2.

[0050] In addition, a first external thread 13 is provided on the outer wall of the first connector 1, and a first internal thread 25 is provided on the inner wall of the locking component 2, and the first external thread 13 is matched and connected with the first internal thread 25. When the first connector 1 and the locking component 2 are configured to be in a locked state, the protrusion of the free end 112 is clamped in the receiving groove 211. When the first connector 1 and the locking component 2 are configured to be in an unlocked state, the protrusion of the free end 112 is in contact with the inner wall of the locking component 2.

[0051] During use of the connection structure provided by the utility model, the second connector 3 passes through the locking component 2 and is threadedly connected to the housing 4. The core shafts of the first connector 1 and the second connector 2 are butted, and the radial relative positions of the two are fixed. The locking component 2 rotates relative to the first connector 1, so that the first internal thread 25 rotates along the first external thread 13, and the protrusion of the free end 112 is pressed by the inner wall of the locking component 2 toward the direction of the groove 12. When the free end 112 rotates to the receiving groove 211, the pressure on the free end 112 disappears, and under the action of elastic force, the protrusion of the free end 112 rebounds and is locked in the receiving groove 211. Since the protrusion of the free end 112 is locked in the receiving groove 211, and the locking component 2 and the first connector 1 also include a threaded connection, the first connector, the second connector and the locking component in the connection structure can be connected very reliably and will not be unlocked due to external forces such as vibration and shaking or misoperation.

[0052] When the first connector 1 and the second connector 2 need to be unlocked, the raised portion of the free end 112 is pressed toward the groove 12, and the locking component 2 is rotated. The inner wall of the locking component 2 is in contact with the raised portion of the free end 112, so that the first connector 1 is withdrawn from the locking component 2 to complete the unlocking.

[0053] As mentioned above, the connection structure proposed by the utility model cleverly utilizes the connection relationship between the first connector, the second connector and the locking component, and designs a second locking structure with a very simple structure to limit the second connector from being away from the first connector, and locks the relative position of the first connector and the locking component through the first locking structure. The locking structure is reliable and will not be separated due to vibration, misoperation, etc., especially in the case where the first connector and the locking component have a double locking structure with a thread and a first locking structure, the reliability of the locked connection between the first connector and the second connector can be further improved, and safety can be increased. In addition, the first locking structure is also convenient for unlocking.

[0054] In one embodiment of the utility model, a connector is provided, the connector comprising the connection structure as described above, wherein the first connector 1 is any one of a male plug or a female plug of the connector, the second connector 3 is the other, and the locking component 2 is used to lock the relative positions of the first connector 1 and the second connector 3.

[0055] In one embodiment of the present invention, a locking component is provided. The locking component includes the first locking structure as described above.

[0056] It should be noted that the above-mentioned connector and locking component embodiments and the connection structure embodiments belong to the same inventive concept, and the entire contents of the connection structure embodiments are incorporated into the connector and locking component embodiments by reference.

[0057] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0058] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
