Description

Technical Field

[0001] This utility model relates to the technical field of connectors, and in particular to a coupling guide structure. Background Technology

[0002] In a conventional D-SUB connector mating structure, both the male and female components' housings and inserts are secured with screws. When the male and female components mate, they rely on the housing and insert for guidance, resulting in a large gap and ineffective restriction of horizontal movement. Therefore, when the male and female components mate at a small angle, they can move relative to each other horizontally, causing misalignment. The male insert cannot be inserted into the female insert, and the male insert may bend or retract, leading to mating failure. Utility Model Content

[0003] Therefore, it is necessary to provide a coupling guidance structure to solve the above-mentioned technical problems.

[0004] A coupling guide structure includes a male terminal assembly and a female terminal assembly. The male terminal assembly includes a first housing and a male connector, the male connector being disposed within the first housing. The female terminal assembly includes a second housing and a female connector, the female connector being disposed within the second housing. The structure further includes:

[0005] A connecting assembly includes a guide and a connector, the guide and the connector being connected. A first housing has a first mounting groove, the guide is partially disposed within the first mounting groove, the connector passes through the male connector and is connected to the first housing, the bottom surface of the guide protrudes beyond the bottom surface of the male connector in the mating direction, and a female end assembly has a second mounting groove. When the male end assembly and the female end assembly are mated, the guide can move along the second mounting groove.

[0006] Optionally, the diameter of the connector is smaller than the diameter of the guide.

[0007] Optionally, the guide and the connector are integrally formed.

[0008] Optionally, the guide member is provided with a relief groove, which is located at the end of the guide member away from the connector.

[0009] Optionally, the guide and the connector are separate components. The guide has a connecting hole and a clearance groove, which are connected. The connector is disposed in the clearance groove and passes through the connecting hole and the male connector to connect with the first housing.

[0010] Optionally, the connector includes a first connecting part and a second connecting part, the diameter of the first connecting part is larger than the diameter of the second connecting part, the first connecting part is disposed in the relief groove, and the second connecting part passes through the connecting hole and the male connector and is connected to the first housing.

[0011] Optionally, the number of connecting components is at least two, and the two connecting components are respectively disposed at both ends of the male connector.

[0012] Optionally, the number of connecting components is at least two, and the two connecting components are respectively disposed at both ends of the male connector.

[0013] This invention provides a coupling guide structure. Because the bottom surface of the guide protrudes beyond the bottom surface of the male connector in the mating direction, when the male and female connectors are inserted relative to each other, the guide will preferentially contact the female connector. When the guide contacts the second mounting groove, it can move along the second mounting groove, thus providing a guiding function and simultaneously restricting the horizontal movement of the male and female connectors, allowing the male connector to be smoothly inserted into the female connector. Therefore, this invention solves the problem of horizontal relative movement between the male and female connectors during mating, which leads to pin bending and retraction failure of the male connector, improving safety, reliability, and durability.

[0030] refer to Figures 1 to 10 This utility model provides a coupling guide structure, which includes a male end component 1, a female end component 2, and a connecting component 3. The male end component 1 includes a first housing 11 and a male insert 12, with the male insert 12 disposed within the first housing 11. The female end component 2 includes a second housing 21 and a female insert 22, with the female insert 22 disposed within the second housing 21. The connecting component 3 includes a guide member 31 and a connector 32, which are connected. The first housing 11 has a first mounting groove 13, and the guide member 31 is partially disposed within the first mounting groove 13. The connector 32 passes through the male insert 12 and connects to the first housing 11. The bottom surface of the guide member 31 protrudes beyond the bottom surface of the male insert 12 in the mating direction. The female end component 2 has a second mounting groove 23. When the male end component 1 and the female end component 2 are mated, the guide member 31 can move along the second mounting groove 23.

[0031] This invention provides a coupling guide structure. Since the bottom surface of the guide member 31 protrudes beyond the bottom surface of the male connector 12 in the mating direction, when the male connector 1 and the female connector 2 are mated, the guide member 31 will preferentially contact the female connector 2. When the guide member 31 contacts the second mounting groove 23, it can move along the second mounting groove 23, thereby providing a guiding function and simultaneously restricting the horizontal movement of the male connector 1 and the female connector 2, allowing the male connector 12 to be smoothly inserted into the female connector 22. Therefore, this invention solves the problem of horizontal relative movement between the male connector 1 and the female connector 2 during mating, which leads to pin bending and retraction failure of the male connector 12, improving safety, reliability, and durability.

[0032] Specifically, the second housing 21 and the female insert 22 enclose each other to form two second mounting grooves 23, which are located at the two ends of the second housing 21 respectively.

[0033] refer to Figure 1 and Figure 2The number of connecting components 3 is at least two, and the two connecting components 3 are respectively disposed in two first mounting slots 13.

[0034] Specifically, the size of the connecting component 3 is smaller than that of the male connector 12, and the connecting component 3 matches the second mounting slot 23. The connecting component 3 and the second mounting slot 23 of the female connector 2 have a small clearance fit, which can effectively limit the relative movement of the male connector 1 and the female connector 2 in the horizontal direction.

[0035] refer to Figure 1 and Figure 3 The female end assembly 2 also includes a fixing member 24, which is disposed in the second mounting groove 23 and passes through the female insert 22 to connect with the second housing 21.

[0036] Specifically, the fastener 24 is a screw, which is used to lock the female insert 22 and the second housing 21 together.

[0037] Furthermore, the number of fasteners 24 is two.

[0038] refer to Figures 1 to 4 In Embodiment 1, the guide 31 and the connector 32 are integrally formed.

[0039] Specifically, the guide member 31 has a clearance groove 33, which is located at the end of the guide member 31 away from the connector 32. The clearance groove 33 is used to avoid the fixing member 24. The diameter of the connector 32 is smaller than the diameter of the guide member 31, and the outer surface of the connector 32 is threaded. The first housing 11 and the male connector 12 are fixedly connected by threaded connection with the first mounting groove 13.

[0040] Furthermore, the clearance groove 33 is provided through the bottom surface of the guide member 31.

[0041] refer to Figures 5 to 10 The difference between Embodiments 2 and 3 and Embodiment 1 is that the connecting component 3 is different. In Embodiments 2 and 3, the guide 31 and the connector 32 are separately provided. The guide 31 has a connecting hole 34 and a clearance groove 33, which are connected. The clearance groove 33 is used to avoid the fixing member 24. The connector 32 is disposed in the clearance groove 33, and the connector 32 passes through the connecting hole 34 and the male connector 12 to connect with the first housing 11.

[0042] Specifically, the connecting hole 34 is located in the middle of the guide member 31, and the clearance groove 33 is provided through the bottom surface of the guide member 31.

[0043] Specifically, the connector 32 includes a first connecting part 321 and a second connecting part 322. The diameter of the first connecting part 321 is larger than the diameter of the second connecting part 322. The first connecting part 321 is disposed in the relief groove 33, and the second connecting part 322 passes through the connecting hole 34 and the male plug 12 to connect with the first housing 11.

[0044] Specifically, connector 32 is a screw.

[0045] refer to Figures 5 to 7 In embodiment two, the guide member 31 is a cylindrical structure with an opening on its bottom surface and a connecting hole 34 on its top surface. (See reference) Figures 8 to 10 In embodiment three, the guide member 31 is a cuboid structure with an opening on the bottom surface and an opening on the side adjacent to the bottom surface. The connecting hole 34 is located on the top surface of the cuboid structure.

[0046] Therefore, the guide member 31 of this utility model contacts the female end assembly 2 before the male connector 12 and guides it, ensuring stable mating of the products. The guide member 31 and the second mounting groove 23 of the female end assembly 2 have a small clearance fit, which can effectively limit the relative movement of the male end assembly 1 and the female end assembly 2 in the horizontal direction. The guide member 31 can effectively protect the male connector 12 and prevent the risk of pin bending or retraction failure when the male connector 12 is mated.

[0047] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
