Description

Technical Field

[0001] This utility model relates to the field of connector housing technology, and more specifically, it relates to a connector structure that is easy to assemble. Background Technology

[0002] In the field of electrical connections, connectors are key components widely used to achieve electrical connections between circuit boards or between cables and equipment. The core of a connector typically includes conductive pins that need to be precisely secured and protected.

[0003] In existing technology, a protective housing is typically placed around the precision pins to protect them from dust and impacts, and to provide mechanical support. A separate pin holder cover is also used to secure the pins and ensure their relative position. A common solution for ensuring reliable assembly between the pin holder cover and the housing is to incorporate a mechanical interlocking structure between them.

[0004] Specifically, a locking block is typically provided on the pin holder cover, and a corresponding latch is provided on the inner wall of the housing. During assembly, the pin holder cover is pressed into the housing, causing the locking block and the latch to engage, forming a "click" lock in place. This locking block and latch mechanism is simple in structure, convenient in assembly, and effectively achieves initial fixation of the pin holder cover and the housing.

[0005] However, this assembly method has a significant drawback: disassembly is extremely inconvenient. Because the locking blocks and clips are typically designed with a one-way locking or interference fit, once assembled, they are tightly engaged. When maintenance, replacement of individual pins, or inspection of internal connections is required, it is difficult for operators to separate them without damaging the fragile plastic locking blocks or clips. Forced prying often leads to clip breakage or block wear, rendering the parts unusable and increasing maintenance costs and time. Therefore, providing a connector structure that is both easy to assemble and easy to disassemble has become a pressing technical problem in this field. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a connector structure that can be quickly assembled and disassembled.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a conveniently assembled connector structure, comprising a bracket cover and a housing that is detachably and fixedly fitted with the bracket cover. A pin is inserted into the bracket cover, extending from both ends of the bracket cover. Connectors are provided on both sides of the bracket cover. A slot adapted to the connector is provided on the housing. The connector is elastic and includes an extension extending forward from the connector; a rotating portion formed by rotating the extension, with an acute angle between the extension and the rotating portion; and an arc-shaped pressing portion disposed on the rotating portion and protruding outward. The connector achieves elastic engagement with the corresponding connector through the arc-shaped pressing portion.

[0008] The present invention is further configured such that the extension, the rotating part and the arc-shaped pressing part are integrally formed, wherein the included angle between the extension and the rotating part is 20-30 degrees.

[0009] The present invention is further configured such that: the bracket cover includes a cover plate, an insertion interface is provided on the upper end face of the cover plate, and a guide plate is provided on the lower end face, wherein the insertion interface and the guide plate are coaxially arranged, and an annular locking groove adapted to the outer shell port is provided along the periphery of the lower end face of the cover plate, and a sealing element is also provided in the annular locking groove.

[0010] The present invention is further configured such that: the inner wall of the outer shell port is provided with three protruding rings, the protruding rings are distributed in a stepped manner along the port axis, and the height of each protruding ring gradually increases from top to bottom.

[0011] The present invention is further configured such that: the sealing element is elastic, and an annular continuous protrusion is provided on the end face that abuts against the outer shell port, and the protrusion is integrally formed with the sealing element.

[0012] By adopting the above technical solution, the elastic connector and the outer shell slot cooperate to realize the two-way locking mechanism of elastic engagement and reverse retraction. During assembly, the arc-shaped pressing part is pressed inward, and the positive force applied to it by the side wall of the slot is converted into elastic potential energy by the acute angle structure of the rotating part. After reaching the locking position, it is released instantly to achieve self-locking. During disassembly, the separation can be completed by pulling out the connector, making the assembly of the bracket cover and the outer shell simpler. Attached Figure Description

[0019] Reference Figures 1 to 5 The embodiments of this utility model will be further described below.

[0020] A conveniently assembled connector structure includes a bracket cover 1 and a housing 2 that is detachably and fixedly fitted to the bracket cover 1. Pins 3 are inserted into the bracket cover 1, extending from both ends of the bracket cover 1. Connectors 4 are provided on both sides of the bracket cover 1. The housing 2 has slots 20 adapted to the connectors 4. Each connector 4 is elastic and includes an extension 40 extending forward from the connector 4; a rotating portion 41 formed by rotating the extension 40, forming an acute angle with the extension 40; and an arc-shaped pressing portion 42 disposed on the rotating portion 41 and protruding outward by 50 degrees. The connector 4 achieves elastic engagement with the corresponding connector 4 through the arc-shaped pressing portion 42. The extension 40, rotating portion 41, and arc-shaped pressing portion 42 are integrally formed, with the angle between the extension 40 and the rotating portion 41 being 20-30 degrees.

[0021] The bracket cover 1 includes a cover plate 10. An insertion interface 11 is provided on the upper end face of the cover plate 10, and a guide plate 12 is provided on the lower end face. The insertion interface 11 and the guide plate 12 are coaxially arranged. An annular locking groove 13, adapted to the port of the outer shell 2, is provided along the periphery of the lower end face of the cover plate 10. A sealing element 5 is also provided within the annular locking groove 13. Three raised rings 21 are provided on the inner wall of the port of the outer shell 2. The raised rings 21 are distributed in a stepped manner along the axial direction of the port, with the height of each raised ring gradually increasing from top to bottom. The sealing element 5 is elastic, and an annular continuous protrusion 50 is provided on the end face that abuts against the port of the outer shell 2. The protrusion 50 is integrally formed with the sealing element 5.

[0022] During assembly of the bracket cover 1 and the outer casing 2, the bracket cover 1 is fastened towards the port of the outer casing 2, thus closing the port of the outer casing 2. The port of the outer casing 2 is inserted into the annular locking groove 13 of the cover plate 10. The continuous protrusion 50 on the sealing element 5 and the raised edge ring 21 on the inner wall of the port of the outer casing 2 achieve a sealing fit. At the same time, the elastic connector 4 is inserted into the slot 20 of the outer casing 2 for engagement. After the acute angle is compressed and reduced, it rebounds and applies force. The rotating part 41 and the arc-shaped pressing part 42 tightly abut against the inner wall of the slot 20, thus achieving a fixed assembly of the bracket cover 1 and the outer casing 2. During disassembly, force is applied to pull out the bracket cover 1, causing the elastic connector to be pulled out of the slot 20, which enables quick separation and improves the efficiency of the next power supply assembly procedure.
