[0002] Connectors enable the transmission of electrical energy and signals between two or more different electrical components, and therefore, they are widely used in various fields.

[0003] Sealed connectors are an important type of connector. They have certain sealing properties such as waterproof, oil-proof, and dustproof. In harsh environments such as immersion in water, humidity, and dust, the use of sealed connectors can effectively prevent liquids and dust from entering the interior of the connector, thereby avoiding problems such as short circuits, open circuits, and loose connections.

[0004] In existing sealed connectors, one or more sealing rings are usually placed inside the connector housing, and the sealing rings are compressed by the connector housing / mating structure. When the sealing rings are compressed, they are squeezed against the connector housing / mating structure to achieve sealing performance.

[0005] The aforementioned sealed connectors suffer from problems such as aging, corrosion, and dislocation of the sealing rings. Their sealing performance is still insufficient for extreme and harsh environments such as dusty environments (e.g., construction sites and outdoor areas), deep water environments, and sports environments.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This embodiment provides a sealed connector for transmitting electrical energy and signals between two or more different electrical components. This embodiment takes one end of the connector (i.e., the male end or the female end) as an example to specifically illustrate the technical solution of this utility model.

[0023] Please refer to Figures 1-4. The sealed connector of this embodiment includes a connector body 10 and a sealing cap component 20.

[0024] The sealing cap component 20 is an integrally injection-molded engineering plastic cap-shaped component.

[0025] The connector body 10 includes at least a connector housing component 101, which is an integrally injection-molded engineering plastic shell component used as the structural support base and functional support base of the sealed connector in this embodiment; the end of the connector housing component 101 is configured as a plug end 101a, which is adapted to be plugged into the other end of the connector.

[0026] The sealing cap component 20 is adapted to be sleeved on the connector housing component 101 of the connector body 10.

[0027] The sealing cap component 20 is adapted to be fixedly connected to external components, and when the sealing cap component 20 is fixedly connected to external components, the following applies:

[0028] The sealing cap member 20 can cover the insertion end 101a of the connector housing member 101, and the sealing cap member 20 can apply force to the connector housing member 101 in the axial direction so that the connector housing member 101 can apply force to its insertion end 101a in the axial direction further outward.

[0029] Specifically, a first sealing rib 101b is formed on the surface of the connector housing component 101. The first sealing rib 101b is an integrally formed rib structure on the surface of the connector housing component 101. A second sealing rib 202 is disposed in the inner ring of the sealing cap component 20. The second sealing rib 202 is an integrally formed rib structure in the inner ring of the sealing cap component 20. When the sealing cap component 20 is fixedly connected to an external component, the second sealing rib 202 of the sealing cap component 20 can apply force to the first sealing rib 101b of the connector housing component 101 in the axial direction, so that the connector housing component 101 can apply force to the outer side of its insertion end 101a in the axial direction.

[0030] More specifically, the inner ring of the sealing cap component 20 is provided with an internal thread body 201, which is integrally injection molded with the sealing cap component 20; the internal thread body 201 of the sealing cap component 20 is adapted to mate with the external thread body of an external component (such as the housing, flange, or external threaded connecting disc at the other end of the connector) to fix the sealing cap component 20 to the external component; when the sealing cap component 20 is tightened, the second sealing rib 202 of the sealing cap component 20 can apply force to the first sealing rib 101b of the connector housing component 101 in the axial direction.

[0031] Furthermore, the sealed connector in this embodiment also includes a sealing ring 30, which is made of rubber, silicone, or elastic plastic. The sealing ring 30 is sleeved on the surface of the insertion end 101a of the connector housing component 101.

[0032] Furthermore, the first sealing rib 101b is positioned at the root of the insertion end 101a of the connector housing member 101; when the connector housing member 101 applies force in the axial direction toward the outer side of its insertion end 101a, the two sides of the sealing ring 30 are respectively pressed by the external component and the first sealing rib 101b of the connector housing member 101.

[0033] In this embodiment of the sealed connector, during use, the insertion end 101a of the connector housing component 101 is inserted and engaged with the other end of the connector. Then, the sealing cap component 20 is pushed forward and rotated, causing the internal thread 201 of the sealing cap component 20 to engage with the external thread of an external component (e.g., the housing, flange, or external threaded connecting disc at the other end of the connector), thus fixing the sealing cap component 20 to the external component. At this time, the sealing cap component 20 covers the insertion end 101a of the connector housing component 101, providing a first sealing protection. When the sealing cap component 20 is tightened, the second sealing engagement rib 2 of the sealing cap component 20... 02 can apply force along the axial direction to the first sealing rib 101b of the connector housing component 101, so that the connector housing component 101 can apply force in the axial direction to the outer side of its plug end 101a. The two sides of the sealing ring 30 are respectively pressed by the external component (i.e. the other end of the connector) and the first sealing rib 101b of the connector housing component 101, providing a second sealing protection. If the plug end 101a of the connector housing component 101 also abuts against the external component (i.e. the other end of the connector), a third sealing protection can be provided through the abutment and engagement between the plug end 101a of the connector housing component 101 and the external component.

[0034] This embodiment also provides a wire harness assembly, which includes the aforementioned sealed connector.

[0035] The wiring harness assembly of this embodiment also includes a wiring harness body 40, which includes at least a plurality of cables, which can be power lines or signal lines. The wiring harness body 40 is covered with an outer sheath, which is used for insulation and signal shielding. The wiring harness body 40 is connected to the connector body 10 according to the wiring sequence. Specifically, the cores of the cables of the wiring harness body 40 are crimped / soldered to the terminals of the connector body 10. A portion of the outer sheath of the wiring harness body 40 is wrapped and fixed by the connector housing member 101 of the connector body 10.

[0036] In this embodiment, the sealed connector and the wire harness assembly using it have a sealing cap member 20 that can cover the insertion end 101a of the connector housing member 101. Furthermore, the sealing cap member 20 can apply force to the connector housing member 101 in the axial direction, so that the connector housing member 101 can apply force to its insertion end 101a in the axial direction. In this way, a stable and reliable sealing structure can be provided for the connector, thereby improving the sealing performance, stability, safety and service life of the connector.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
