Description

Technical Field

[0001] This utility model relates to the technical field of connectors, and specifically discloses a locking structure for an MSD switch and a connector having the locking structure. Background Technology

[0002] The locking structures of current MSD energy storage manual maintenance switch products are mainly divided into single-level and multi-level locking / unlocking structures.

[0003] Single-level locking / unlocking structures typically utilize buttons with elastic deformation properties for locking and unlocking. Their advantage is quick unlocking, but their disadvantage is the potential for accidental locking. Multi-level locking / unlocking structures, such as the locking mechanism for an MSD switch disclosed in patent CN222422563U, design a first and second locking part. During unlocking, the secondary locking member is pulled in the opposite direction to the pushing direction, causing the first abutment to release its pressure on the first locking part or reduce its pressure. Then, the root of the first locking part is pressed perpendicular to the housing direction. The elastic deformation of the first locking part causes the end locked to the second locking part to disengage from the second locking part, thus completing the unlocking. However, multi-level locking / unlocking structures have the disadvantage of a cumbersome locking / unlocking process, requiring a certain level of proficiency. In emergency situations, they may not unlock or may take a long time to unlock, which is detrimental to safety. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a locking structure for an MSD switch and a connector having the locking structure.

[0005] On the one hand, this utility model discloses a locking structure for an MSD switch, which adopts the following technical solution:

The two unlocking components are inserted into a sliding groove and can slide laterally. The top of the sliding groove has two limiting blocks distributed on the left and right. The limiting parts of the two unlocking components are aligned with the two limiting blocks in the longitudinal direction. An unlocking opening is left between the two limiting blocks to allow the two limiting parts to move longitudinally. When the pressing part of the two unlocking components is compressed by an external force, the two unlocking components slide towards each other, and the limiting parts of the two unlocking components move to the unlocking opening and disengage from the longitudinal limitation of the limiting blocks.

[0013] Preferably, the top of the limiting block of the plug housing is provided with an inclined guide slide, and the limiting part of the unlocking member is provided with a guide slope that cooperates with the guide slide.

[0014] On the other hand, this utility model discloses a connector that includes a plug assembly and a socket assembly, and has the above-mentioned locking structure for an MSD switch, the locking structure being used to lock and fix the plug assembly to the socket assembly.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] This invention features a locking handle with two sliding unlocking components. The plug housing is equipped with a limiting block and an unlocking opening. Simply pressing the pressing part simultaneously will disengage the limiting part from the longitudinal limit.

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] This embodiment discloses a locking structure for an MSD switch and a connector having the locking structure. The connector includes a plug assembly and a socket assembly, and the locking structure is used to lock and fix the plug assembly to the socket assembly. (Refer to...) Figure 1-2 The socket assembly includes a socket housing 1, the plug assembly includes a plug housing 2, and the locking structure includes a locking handle 3. The plug housing 2 is provided with a connecting shaft 21, and the locking handle 3 is rotatably connected to the connecting shaft 21 of the plug housing 2. The locking handle 3 is provided with a limiting arc groove 31, and the socket housing 1 is provided with a limiting slider 11 that is slidably connected within the limiting arc groove 31. The specific structure of the socket assembly and the plug assembly can be found in patent 202321576787.7, and will not be elaborated here.

[0036] As an improvement, refer to Figure 3-9The locking handle 3 of the locking structure is slidably connected to two unlocking parts 4 distributed on the left and right. Each unlocking part 4 has a pressing part 42, an elastic reset part 43, and a limiting part 44. The plug housing 2 is provided with a sliding groove 22. The limiting parts 44 of the two unlocking parts 4 are inserted into the sliding groove 22 and can slide laterally. The top of the sliding groove 22 has two limiting blocks 23 distributed on the left and right. The limiting parts 44 of the two unlocking parts 4 and the two limiting blocks 23 are directly opposite each other in the longitudinal direction. An unlocking opening is left between the two limiting blocks 23 to allow the two limiting parts 44 to move longitudinally. 24; When the pressing part 42 of the two unlocking parts 4 is compressed by external force to the elastic reset part 43, the two unlocking parts 4 slide towards each other, and the limiting part 44 of the two unlocking parts 4 moves to the unlocking opening 24 and disengages from the longitudinal limit of the limiting block 23; when the external force is removed, the elastic reset part 43 of the two unlocking parts 4 elastically drives the two unlocking parts 4 to slide away from each other, and the limiting part 44 of the two unlocking parts 4 resets to the locking position opposite to the two limiting blocks 23, thereby realizing double-locking single-level locking, which not only prevents mis-locking, but also ensures that the unlocking process is simple and quick.

[0037] As a preferred embodiment, the unlocking component 4 includes a main body 41, the locking handle 3 has a cavity for the main body 41 to be inserted, the elastic reset part 43 is disposed on one side of the main body 41 in the lateral direction, and the pressing part 42 is disposed on the other side of the main body 41 in the lateral direction. The main bodies 41 of the two unlocking components 4 are arranged vertically along the longitudinal direction. Of course, in other embodiments, the main bodies 41 of the two unlocking components 4 can also be designed to be distributed horizontally. However, in this embodiment, the main bodies 41 are preferably designed to be distributed vertically along the longitudinal direction, which makes full use of the longitudinal space of the locking handle 3 and makes the installation of the unlocking component 4 in the locking handle 3 more compact and reasonable.

[0038] As a preferred option, refer to Figure 7 The locking handle 3 has an anti-disengagement protrusion 32 on the inner wall of its cavity, and an anti-disengagement spring 411 on its main body 41. The free end of the anti-disengagement spring 411 abuts against the anti-disengagement protrusion 32. The anti-disengagement protrusion 32 has two upper and two lower protrusions corresponding to the anti-disengagement springs 411 of the two unlocking parts 4, respectively. By designing the cooperation between the anti-disengagement protrusion 32 and the anti-disengagement spring 411, not only is it effective to prevent the unlocking part 4 from falling out during the sliding process, thus improving the reliability of use, but it is also easy to assemble. During assembly, the main body 41 of the unlocking part 4 can be inserted into the cavity of the locking handle 3. The anti-disengagement spring 411 is first deformed by the compression of the inner wall of the cavity until it passes the anti-disengagement protrusion 32. Then, the free end of the anti-disengagement spring 411 elastically recovers and abuts against the anti-disengagement protrusion 32, thereby completing the assembly and fixation of the unlocking part 4 in the locking handle 3. The assembly efficiency is high.

[0039] As a preferred embodiment, the elastic reset part 43 is a spring. The main body 41 is provided with a first spring positioning groove into which one end of the spring is inserted. The locking handle 3 is provided with a positioning block 33, and the positioning block 33 is provided with a second spring positioning groove into which the other end of the spring is inserted. The positioning block 33 has two upper and lower parts corresponding to the springs of the two unlocking parts 4, respectively. The first spring positioning groove and the second spring positioning groove facilitate accurate spring installation and positioning, and smooth compression and reset processes. In other embodiments, the elastic reset part 43 can also be a spring sheet or other elastic element integrally formed with the main body 41. In this embodiment, the elastic reset part 43 is designed as a spring part, which is readily available and cheaper to manufacture.

[0040] As a preferred embodiment, the inner wall of the locking handle 3 cavity is provided with a laterally extending guide groove 34, and the side of the main body 41 is provided with a guide protrusion 412 that matches and slides with the guide groove 34. The guide protrusion 412 can preferably be provided on both the front and rear sides of the main body 41. Figure 9 The guide groove 34 and the guide protrusion 412 work together to effectively guide the unlocking component 4 to slide laterally, avoiding jamming and improving the smoothness of unlocking.

[0041] As a preferred solution, combined with Figure 7 The upper part of the pressing part 42 of the unlocking part 4 is connected to the main body part 41, and the lower part of the pressing part 42 is provided with a balancing block 421. The locking handle 3 is provided with a slot 35 for the balancing block 421 to be inserted. By designing the balancing block 421 at a position away from the main body part 41 on the pressing part 42, the cooperation between the balancing block 421 and the slot 35 makes the pressing action more even, so that the two main body parts 41 distributed at the top and bottom will not be tilted when subjected to force, thus improving the smoothness of the operation process.

[0042] As a preferred embodiment, the locking handle 3 has upper and lower cavities for the main bodies 41 of the two unlocking components 4 to be inserted into, and a reinforcing post 36 is provided on the inner wall between the upper and lower cavities, as shown in the reference. Figure 4 By designing the reinforcing column 36, the structural strength of the locking handle 3 is enhanced, preventing deformation after long-term use and improving product lifespan.

[0043] As a preferred option, refer to Figure 8The top of the limiting block 23 of the plug housing 2 is provided with an inclined guide slide 231, and the limiting part 44 of the unlocking member 4 is provided with a guide slope 441 that cooperates with the guide slide 231. Through the cooperative design of the guide slide 231 and the guide slope 441, during the unlocking process, the guide slope 441 slides along the guide slide 231, reducing frictional resistance and making the unlocking action more effortless and smooth. During the locking process, it is only necessary to press down the locking handle 3, so that the guide slope 441 of the limiting part 44 slides inclinedly along the surface of the guide slide 231 of the limiting block 23 of the plug housing 2 until the limiting part 44 crosses the edge of the limiting block 23. After the elastic reset part 43 is compressed, it releases the rebound force, and the limiting part 44 moves to the locking position directly opposite the limiting block 23. Locking can be completed without pressing the unlocking member, making the locking process easier.

[0044] The working principle of the locking structure of this utility model is as follows:

[0045] See Figure 7-8 In the initial state, the limiting part 44 is directly opposite the limiting block 23. At this time, the limiting block 23 restricts the longitudinal movement of the locking handle 3, and the locking handle 3 cannot rotate on the plug housing 2. The limiting slider 11 of the socket housing 1 is restricted in the limiting arc groove 31 of the locking handle 3, thereby realizing the locking between the plug housing 2 and the socket housing 1.

[0046] See Figure 10-11 When unlocking is required, press the pressing part 42 of the two unlocking parts 4 at the same time. At this time, the elastic reset part 43 is compressed, the two unlocking parts 4 move closer to each other, and the limiting part 44 of the two unlocking parts 4 moves closer to each other in the middle of the sliding groove 22 until the limiting part 44 is misaligned with the limiting block 23. At this time, the limiting part 44 can move upward from the unlocking opening 24 and get away from the longitudinal limit of the limiting block 23. The locking handle 3 can rotate on the plug housing 2.

[0047] See Figure 12 When the locking handle 3 rotates a certain angle on the plug housing 2, the opening of the limiting arc groove 31 of the locking handle 3 is directly opposite to the limiting slider 11 of the socket housing 1, at which point the plug housing 2 can be pulled out of the socket housing 1.

[0048] When it is necessary to lock the plug housing 2 and the socket housing 1, align the opening of the limiting arc groove 31 of the locking handle 3 with the limiting slider 11 of the socket housing 1, and then rotate the locking handle 3 until the unlocking part 4 of the locking handle 3 contacts the plug housing 2. At this time, press down the locking handle 3 so that the limiting part 44 of the unlocking part 4 moves to the position directly opposite the limiting block 23 of the plug housing 2 under the elastic force of the elastic reset part 43, thereby achieving the locking of the plug assembly and the socket assembly.

The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
