Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a waterproof floating connection component. Background Technology

[0002] Connectors are components frequently encountered by electronic engineers. Their function is quite simple: to bridge gaps in circuits or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. Connectors come in a wide variety of forms and structures, but they are primarily composed of four basic structural components: contacts, housing, insulator, and accessories. In the industry, they are commonly referred to as sheaths, connectors, or plastic shells.

[0003] In some fields, the insertion and extraction forces between connectors are relatively large to prevent loosening. For example, in the automotive industry, the direct insertion and extraction process can easily damage the product. To address this issue, the connector female socket is designed with a floating function. During the insertion of the male connector into the female socket, there is a certain amount of floating space in both the horizontal and vertical directions, which can distribute the insertion and extraction forces and alleviate mechanical rigidity-related damage. While this design effectively prevents damage to the female socket due to insertion, such connectors have poor waterproof performance. Furthermore, given the variable operating environments, water can easily enter in humid environments, causing the connector to malfunction. Therefore, it is necessary to improve existing connectors. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide a waterproof floating connection component, which can effectively solve the problem that existing connectors are prone to water ingress in environments with high moisture content, causing the connectors to malfunction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waterproof floating connection assembly includes a female and a male connector that are pluggable to each other;

[0007] The female connector includes a female connector panel, a female connector body, and multiple female connector terminals. The female connector panel has a female connector mounting position. The female connector body is installed and fixed in the female connector mounting position. The front end of the female connector body extends forward out of the female connector mounting position, and the rear end of the female connector body extends backward out of the female connector mounting position. A floating space is formed between the rear peripheral side of the female connector body and the inner wall of the female connector mounting position. The female connector body has a slot, and the multiple female connector terminals are all disposed on the female connector body.

[0008] The male connector includes a male connector panel, a male connector body, and multiple male connector terminals. The male connector panel has a male connector mounting position, and the male connector body is installed and fixed in the male connector mounting position. The male connector body has a plug-in portion that is adapted to the slot. The plug-in portion has multiple male connector terminal slots. A waterproof portion extends outward from the peripheral side of the male connector body. A first waterproof ring is provided on the front side of the waterproof portion. The front side of the waterproof portion and the first waterproof ring are tightly fitted to the male connector panel. The multiple male connector terminals are all disposed in the corresponding male connector terminal slots, and each male connector terminal is fitted with a second waterproof ring. The second waterproof ring is in close contact with the inner wall surface of the male connector terminal slot.

[0009] As a preferred embodiment, the female body includes a first body portion and a second body portion. The first body portion has the aforementioned slot, and the second body portion is assembled and fixed to the rear end of the first body portion. A floating space is formed between the rear peripheral side of the second body portion and the inner wall surface of the female body mounting position.

[0010] As a preferred embodiment, the bottom end of the slot has a plurality of terminal posts protruding forward, each of which has a female terminal slot with an opening facing forward. Each female terminal includes an integrally formed female contact part and a female wiring part, and each female contact part is located in the female terminal slot.

[0011] As a preferred embodiment, each female connector has a contact cavity with an opening facing forward and adapted to the male connector terminal.

[0012] As a preferred embodiment, the contact cavity is provided with a connector for making contact and conducting with the male terminal.

[0013] As a preferred embodiment, each male terminal slot has a first limiting portion. Each male terminal includes an integrally formed male contact portion, a male body portion, and a male wiring portion. The male contact portion, male body portion, and male wiring portion are all located within the male terminal slot. A retaining ring is fitted onto the male body portion, and the retaining ring has multiple elastic limiting ends. A second limiting portion protrudes outward from the peripheral side of the male body portion. The second limiting portion is located in front of the retaining ring. When the male terminal is assembled in place, the multiple elastic limiting ends abut against the first limiting portion, and the second limiting portion abuts against the first limiting portion.

[0014] As a preferred embodiment, the peripheral side of the male head body is provided with a third limiting part protruding outward, and the third limiting part and the second limiting part form a groove, in which the aforementioned second waterproof ring is embedded.

[0015] As a preferred embodiment, the female connector body has a guide post protruding forward, and the male connector body has a guide cavity adapted to the guide post. When the female connector and the male connector are inserted into the position, the guide post is inserted into the guide cavity.

[0016] As a preferred embodiment, the female connector body is provided with a first annular rib, which forms a slot. The female connector panel is provided with a second annular rib, which surrounds the first annular rib. The male connector panel is provided with a third annular rib. When the female connector and the male connector are inserted into place, the third annular rib is located between the first and second annular ribs.

[0017] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0018] By installing and fixing the female connector body in the female connector mounting position, the rear end of the female connector body extends backward into the female connector mounting position, and a floating space is formed between the peripheral side of the rear end of the female connector body and the inner wall of the female connector mounting position. This allows the insertion and removal force of the male and female connectors to be reduced, thus reducing the stress on the female connector body and preventing product damage. In addition, the front side of the waterproof part and the first waterproof ring are tightly fitted with the male connector panel, and each male connector terminal is fitted with a second waterproof ring. The second waterproof ring is in close contact with the inner wall of the male connector terminal slot, which greatly improves the waterproof performance. This makes it difficult for water to enter the connection component even in a humid environment, ensuring the normal use of the connector assembly.
