Waterproof connector with blind bolt structure

Abstract

The utility model provides a waterproof connector with a blind bolt structure. The waterproof connector comprises a connector body and a blind bolt. A silica gel waterproof ring is arranged in the connector body, and a plurality of terminal through holes are formed in the silica gel waterproof ring and used for containing and sealing terminals in the connector. The whole blind bolt is cylindrical, an annular groove is formed in the middle of the blind bolt, and the annular groove surrounds the periphery of the blind bolt by a circle. When the blind bolt is inserted into the terminal hole of the connector, the annular groove of the blind bolt and the terminal through hole of the silica gel waterproof ring form an inverted hanging table, so that the blind bolt is not easy to loosen from the terminal hole of the connector body.

Description

Technical Field

[0001] The present application relates to the field of connectors, and in particular to a waterproof connector with a blind bolt structure. Background Art

[0002] In the electronic equipment sector, waterproof connectors are critical components for ensuring stable operation in a variety of environments. Traditional waterproof connectors typically employ various methods to achieve waterproofing, with blind plugs being a common design. Blind plugs are primarily used to seal the connector's terminal openings, preventing moisture or other liquids from seeping into the connector, thereby protecting circuits and electronic devices from damage.

[0003] However, existing waterproof connectors have some shortcomings in their blind bolt design. On the one hand, some connectors secure the blind bolt by providing a complex interference structure between the blind bolt and the plastic body. While this approach improves the stability of the blind bolt to a certain extent, the complex structure not only increases manufacturing costs but can also cause difficulties during assembly, reducing production efficiency. On the other hand, if there is no effective restraining structure between the blind bolt and the plastic body, the blind bolt can easily detach from the connector when subjected to external forces. This not only affects the waterproof performance of the connector but can also pose a threat to the safe operation of the device. Utility Model Content

[0004] The purpose of the present application is to provide a waterproof connector with a blind bolt structure that is simple in structure, stable and reliable, and easy to plug and unplug.

[0005] In order to achieve the above objectives, this application provides the following technical solutions:

[0006] A waterproof connector with a blind bolt structure includes a connector body and a blind bolt. A silicone waterproof ring is provided in the connector body, and a plurality of terminal through-holes are provided on the silicone waterproof ring. The blind bolt is cylindrical as a whole, and an annular groove is provided in the middle of the blind bolt. The annular groove is arranged around the outer circumference of the blind bolt. When the blind bolt is inserted into the terminal hole of the connector, the annular groove of the blind bolt and the terminal through-hole of the silicone waterproof ring form an inverted hanging platform, so that the blind bolt is not easily loosened from the terminal hole of the connector body.

[0007] In one embodiment, an inclined sealing surface is provided on the side of the annular groove near the tail of the blind plug.

[0008] In one embodiment, a limiting portion is provided near the tail end of the blind bolt, and the limiting portion is used to limit the length of the blind bolt inserted into the connector body.

[0009] In one embodiment, a tapered guide portion is provided at the front end of the blind bolt.

[0010] The beneficial effects of this application are:

[0011] (1) The waterproof connector of this application forms an inverted hanging platform by designing an annular groove in the middle of the blind bolt and the terminal through-hole on the silicone waterproof ring, which effectively fixes the blind bolt without the need for a complex interference structure. This design simplifies the overall structure of the connector, reduces manufacturing costs, and improves production efficiency.

[0012] (2) The inverted hanging platform structure formed by the annular groove and the terminal through-hole provides a reliable limit for the blind bolt, effectively preventing the blind bolt from detaching from the connector when subjected to external force. This design improves the waterproof performance and safety of the connector, ensuring the stable operation of circuits and electronic equipment in harsh environments.

[0020] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, the waterproof connector with a blind plug 2 in this embodiment includes a connector body 1 and a blind plug 2. A silicone waterproof ring 3 is disposed within the connector body 1. The silicone waterproof ring 3 is provided with multiple terminal holes 4 for accommodating and sealing the terminals within the connector. The blind plug 2 is generally cylindrical in shape, with an annular groove 21 disposed in the center. The annular groove 21 surrounds the outer circumference of the blind plug 2.

[0022] like Figure 4As shown, when the blind bolt 2 is inserted into the terminal hole of the connector, the annular groove 21 of the blind bolt 2 and the terminal through hole 4 of the silicone waterproof ring 3 form an inverted hanging platform, so that the blind bolt 2 is not easy to loosen out of the terminal hole of the connector body 1.

[0023] In practice, the depth and width of annular groove 21 are rationally designed based on the material and thickness of silicone waterproof ring 3 to ensure the stability and sealing of the inverted mounting bracket. Furthermore, the materials used for connector body 1 and blind plug 2 are waterproof and mechanically strong, meeting the requirements of electronic devices for waterproof connectors.

[0024] like Figure 1 As shown, the blind plug 2 of this embodiment is provided with an inclined sealing surface 22 on the side of the annular groove 21 near the rear end of the blind plug 2. The inclined sealing surface 22 is provided to improve the sealing performance between the blind plug 2 and the silicone waterproof ring 3, preventing moisture or other contaminants from penetrating into the connector through the small gap between the blind plug 2 and the silicone waterproof ring 3.

[0025] like Figure 1 As shown, the blind bolt 2 of this embodiment is provided with a limit portion 23 near the tail end. The limit portion 23 is used to limit the length of the blind bolt 2 inserted into the connector body 1 to prevent the blind bolt 2 from being inserted too deep and damaging the terminals or other components inside the connector.

[0026] like Figure 1 As shown, the front end of the blind bolt 2 of this embodiment is provided with a tapered guide portion 24. The provision of the tapered guide portion 24 is intended to simplify the insertion and removal process of the blind bolt 2, improving insertion and removal convenience. The tapered guide portion 24 also serves as a guide during the insertion and removal process, preventing the blind bolt 2 from drifting or getting stuck during insertion.
