Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings. In the specification, the same or similar reference numerals denote the same or similar components. The following description of the embodiments of the present invention with reference to the accompanying drawings is intended to explain the general inventive concept of the present invention and should not be construed as limiting the invention.

Furthermore, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in schematic form in order to simplify the drawing.

According to one general technical concept of the present invention, there is provided a connector for connecting a cable assembly with an outer shield. The connector includes: a housing; and a shield member, at least a part of which is provided in the housing, the shield member penetrating the housing from the inside to the outside in an axial direction of the housing, the shield member having a shield connecting portion located outside the housing, a radially outer surface of the shield connecting portion being adapted to be in contact with and electrically connected to an outer shield of the cable assembly. FIG. 1 shows an exploded perspective view of a connector assembly according to an exemplary embodiment of the present invention; fig. 2 shows a longitudinal cross-sectional view of the connector 100 of the connector assembly shown in fig. 1.

As shown in fig. 1 and 2, in the illustrated embodiment, the connector 100 includes a housing 110 and a shield 120. The housing 110 is an insulating housing made of an insulating material. The shield 120 is made of a conductive material, for example, may be made of metal. A portion of the shield 120 is disposed in the housing 110.

As shown in fig. 1-2 and 8, in the illustrated embodiment, the shield 120 penetrates the housing 110 from inside to outside in the axial direction of the housing 110, and the shield 120 has a shield connecting portion 121 extending to the outside of the housing 110. The radially outer surface of the shield connection portion 121 is adapted to be in contact with and electrically connected to the outer shield 1 of the cable assembly. Thus, the outer shield 1 of the cable assembly can be electrically connected to the shield connection part 121 of the shield member 120 with ease, and thus, an additional outer shield case does not need to be provided for the connector, simplifying the structure of the connector. In addition, in the illustrated embodiment, most of the shielding element 120 is still located inside the housing 110, and is not affected by the external environment, thereby improving the shielding effect.

As shown in fig. 1 and 2, in the illustrated embodiment, the housing 110 is an injection molded part that is insert molded over the shield 120 such that a portion 123 of the shield 120 is embedded and engaged in a wall portion of the housing 110. The manufacture is very convenient, and the reliable joint between the shell 110 and the shielding piece 120 can be ensured through injection molding, so that the waterproof and dustproof functions are achieved to a certain extent. In an exemplary embodiment of the present invention, in order to improve the bonding strength, a mesh-shaped score 121b, a protrusion, or a recess may be formed on a radially outer surface of the shield connection part 121 of the shield 120. In this way, the coupling strength between the shield 120 and the outer shield 1 of the cable assembly can be improved.

Note that the manufacturing of the housing 110 of the present invention is not limited to the foregoing embodiment, for example, in another exemplary embodiment of the present invention, the housing 110 may be an injection molded part molded separately from the shield 120, and the housing 110 is assembled to the shield 120.

As shown in fig. 1 and 2, in the illustrated embodiment, the shield 120 is cylindrical. The housing 110 includes a peripheral wall 111 located outside the shield 120 and a terminal support 112 located inside the shield 120. The aforementioned part 123 of the shield 120 is embedded and engaged between one end of the outer peripheral wall 111 and the terminal support body 112. Therefore, the shield 120 is supported between the inside of one end of the outer peripheral wall 111 and the terminal support body 112.

As shown in fig. 1 and 2, in the illustrated embodiment, due to the different materials of the shield 120 and the housing 110, a gap may occur therebetween when the shield expands with heat or contracts with cold. Therefore, in order to ensure reliable waterproof performance, sealing surfaces are formed on the outer end 112a of the terminal support body 112 and the shield member 120, respectively, for radial contact with the first seal member 131 to seal the mating interface therebetween.

As shown in fig. 1 and 2, in the illustrated embodiment, the connector 100 further includes a first seal 131. The first seal 131 is radially disposed between the terminal supporter 112 of the housing 110 and the shield 120 to seal a mating interface between the terminal supporter 112 and the shield 120. In this way, moisture and dust can be prevented from entering the connector 100 from the inside of the shield member 120.

As shown in fig. 1 and 2, in the illustrated embodiment, a groove 101 is formed between the outer end 112a of the terminal support 112 and the shield 120, and a first sealing member 131 is disposed in the groove 101. In the illustrated embodiment, the first seal 131 is an elastic seal, such as an elastic seal ring or an elastic gland, which is radially compressed between the outer circumferential surface of the outer end 112a of the terminal support 112 and the inner circumferential surface of the shield 120. However, the present invention is not limited to the illustrated embodiment, and for example, the first sealing member 131 may be a sealant filled in the groove 101.

Fig. 3 shows a longitudinal cross-sectional view of a mating connector 200 of the connector assembly shown in fig. 1; fig. 4 shows a schematic view of the connector 100 shown in fig. 2 mated with the mating connector 200 shown in fig. 3.

In the illustrated embodiment, the shield 120 is shaped with its inner end 122 spaced from the peripheral wall 111 of the housing 110, i.e., as shown in fig. 2 and 4, there is a gap 102 between the inner end 122 of the shield 120 and the peripheral wall 111 of the housing 110 that allows insertion of the mating housing 210.

As shown in fig. 1 to 4, in the illustrated embodiment, sealing surfaces are provided on the outer peripheral surfaces of the inner end portion 122 of the shield 120 and the outer peripheral wall 111 of the housing 110, respectively, for radial contact with the second seal 132 to seal the mating interface between the mating housing 210 and the inner end portion 122.

As shown in fig. 1-4, in the illustrated embodiment, the connector further includes a second seal 132 disposed on the outer peripheral surface of the inner end portion 122 of the shield 120. The second seal 132 serves to seal the mating interface between the counterpart housing 210 and the shield 120, thereby preventing moisture and dust from entering the connector 100 and the counterpart connector 200 from between the shield 120 and the counterpart housing 210.

As shown in fig. 1-4, in the illustrated embodiment, the second seal 132 is an elastomeric seal, such as an elastomeric seal ring or elastomeric seal cartridge. As shown in fig. 4, when the connector 100 and the counterpart connector 200 are mated together, the second seal 132 is radially compressed between the inner peripheral surface of the counterpart housing 210 and the outer peripheral surface of the inner end portion 122 of the shield 120, so that the mating interface between the counterpart housing 210 and the shield 120 can be sealed. However, it should be noted that the present invention is not limited to the illustrated embodiment, for example, in another exemplary embodiment of the present invention, the second sealing member 132 may be a sealant filled between the mating housing 210 and the shielding member 120.
