Description

Technical Field

[0001] The present invention relates to a connector and a connector assembly including the connector. Background Technology

[0002] In the prior art, shielded cables typically include a conductor core, an inner insulation layer wrapped around the conductor core, a shielding layer wrapped around the inner insulation layer, and an outer insulation layer wrapped around the shielding layer. The connector connected to this cable typically includes a housing and a shielding element mounted within the housing. One end of the cable is inserted into the connector housing. The shielding layer at one end of the cable is electrically connected to the shielding element via a shielding connector located within the connector housing.

[0003] However, in existing technologies, users sometimes need to use unshielded ordinary cables, which typically lack a shielding layer. To achieve shielding, an additional external shield must be fitted onto the outside of the ordinary cable. However, the shielding of existing cable connectors is located inside the connector housing and cannot connect to this external shield. Therefore, an additional shielding shell needs to be installed outside the connector housing to connect with the external shield. This results in a complex connector structure, and the shielding shell is directly exposed to the external environment, leading to significant resistance variations throughout its lifespan and affecting the shielding effectiveness.

[0035] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. In this specification, the same or similar reference numerals indicate 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 overall inventive concept of the present invention and should not be construed as a limitation thereof.

[0036] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of the embodiments disclosed herein. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the figures.

[0037] According to a general technical concept of the present invention, a connector is provided for connecting a cable assembly with an outer shield. The connector includes: a housing; and a shielding member, at least a portion of which is disposed within the housing, the shielding member extending axially from the inside to the outside of the housing, the shielding member having a shielding connection portion located outside the housing, the radially outer surface of the shielding connection portion being adapted to contact and electrically connect with the outer shielding of the cable assembly. Figure 1 An exploded perspective view of a connector assembly according to an exemplary embodiment of the present invention is shown; Figure 2 show Figure 1 The longitudinal sectional view of connector 100 of the connector assembly shown.

[0038] like Figure 1 and Figure 2 As shown, 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, it may be made of metal. A portion of the shield 120 is disposed within the housing 110.

[0039] Figure 8 A schematic diagram showing a cable assembly according to an exemplary embodiment of the present invention.

[0040] like Figure 1-2 and Figure 8As shown in the illustrated embodiment, the shield 120 extends from the inside to the outside of the housing 110 along its axial direction. The shield 120 has a shielding connection portion 121 extending to the outside of the housing 110. The radially outer surface of the shielding connection portion 121 is adapted to contact and electrically connect with the outer shield 1 of the cable assembly. Thus, the outer shield 1 of the cable assembly can be conveniently electrically connected to the shielding connection portion 121 of the shield 120, eliminating the need for an additional outer shielding shell for the connector and simplifying its structure. Furthermore, in the illustrated embodiment, most of the shield 120 remains inside the housing 110, unaffected by the external environment, thus improving the shielding effect.

[0041] like Figure 1 and Figure 2 As shown in the illustrated embodiment, the housing 110 is an injection-molded part formed on the shielding member 120 by embedding injection molding, such that a portion 123 of the shielding member 120 is embedded and joined to the wall of the housing 110. This manufacturing method is very convenient, and through injection molding, a reliable connection between the housing 110 and the shielding member 120 can be ensured, providing a certain degree of waterproof and dustproof functionality. In an exemplary embodiment of the present invention, to improve the bonding strength, mesh-like grooves 121b, protrusions, or recesses can be formed on the radial outer surface of the shielding connection portion 121 of the shielding member 120. This improves the bonding strength between the shielding member 120 and the outer shield 1 of the cable assembly.

[0042] Please note that the manufacture of the housing 110 of the present invention is not limited to the foregoing embodiments. For example, in another exemplary embodiment of the present invention, the housing 110 may be an injection molded part separately formed from the shield 120, and the housing 110 may be assembled onto the shield 120.

[0043] like Figure 1 and Figure 2 As shown, in the illustrated embodiment, the shield 120 is cylindrical. The housing 110 includes an outer peripheral wall 111 located outside the shield 120 and a terminal support 112 located inside the shield 120. The aforementioned portion 123 of the shield 120 is embedded and engaged between one end of the outer peripheral wall 111 and the terminal support 112. Therefore, the shield 120 is supported between the inner side of one end of the outer peripheral wall 111 and the terminal support 112.

[0044] like Figure 1 and Figure 2As shown in the illustrated embodiment, since the shield 120 and the housing 110 are made of different materials, gaps may appear between them when they expand and contract with heat. Therefore, in order to ensure reliable waterproof performance, sealing surfaces are formed on the outer end 112a of the terminal support 112 and the shield 120, respectively, for radial contact with the first seal 131 to seal the mating interface between them.

[0045] like Figure 1 and Figure 2 As shown in the illustrated embodiment, the connector 100 further includes a first seal 131. The first seal 131 is radially disposed between the terminal support 112 and the shield 120 of the housing 110 to seal the mating interface between the terminal support 112 and the shield 120. This prevents moisture and dust from entering the connector 100 from the interior of the shield 120.

[0046] like Figure 1 and Figure 2 As shown 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 seal 131 is disposed in the groove 101. In the illustrated embodiment, the first seal 131 is an elastic seal, such as an elastic sealing ring or elastic sealing sleeve, that is radially pressed between the outer peripheral surface of the outer end 112a of the terminal support 112 and the inner peripheral surface of the shield 120. However, the present invention is not limited to the illustrated embodiment; for example, the first seal 131 may also be a sealant filled in the groove 101.

[0047] Figure 3 show Figure 1 A longitudinal sectional view of the mating connector 200 of the connector assembly shown; Figure 4 show Figure 2 The connector 100 shown and Figure 3 The diagram shows the mating connectors 200 mated together.

[0048] like Figures 1 to 4 As shown, in the illustrated embodiment, the connector 100's housing 110 has an internal receiving cavity enclosed by its outer peripheral wall 111, and the shield 120 has an inner end portion 122 extending into the internal receiving cavity of the housing 110. In the illustrated embodiment, the shield 120 is shaped such that its inner end portion 122 is spaced apart from the outer peripheral wall 111 of the housing 110, i.e., as... Figure 2 and Figure 4 As shown, there is a gap 102 between the inner end 122 of the shield 120 and the outer peripheral wall 111 of the housing 110, which allows the mating housing 210 to be inserted.

[0049] like Figures 1 to 4As shown in the illustrated embodiment, sealing surfaces are respectively provided on the outer peripheral surface of the inner end portion 122 of the shield 120 and the outer peripheral wall 111 of the housing 110, for radial contact with the second sealing member 132 to seal the mating interface between the mating housing 210 and the inner end portion 122.

[0050] like Figures 1 to 4 As shown 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 is used to seal the mating interface between the mating housing 210 and the shield 120, thereby preventing moisture and dust from entering the connector 100 and the mating connector 200 from between the shield 120 and the mating housing 210.

[0051] like Figures 1 to 4 As shown, in the illustrated embodiment, the second seal 132 is an elastic seal, such as an elastic sealing ring or an elastic sealing sleeve. Figure 4 As shown, when connector 100 and mating connector 200 are mated together, the second seal 132 is radially pressed between the inner circumferential surface of mating housing 210 and the outer circumferential surface of the inner end portion 122 of shield 120, thereby sealing the mating interface between mating housing 210 and shield 120. However, please note that the present invention is not limited to the illustrated embodiment. For example, in another exemplary embodiment of the present invention, the aforementioned second seal 132 may also be a sealant filled between mating housing 210 and shield 120.

[0052] Figure 5 A perspective view of a connector 100 according to an exemplary embodiment of the present invention is shown; Figure 6 show Figure 5 The longitudinal sectional view of connector 100 shown; Figure 7 show Figure 5 An exploded view of connector 100 is shown.

[0053] like Figures 5 to 7 As shown in the illustrated embodiment, the aforementioned connector 100 further includes shielding supports 140 and 150. The shielding supports 140 and 150 are inserted into the radially inner side of the shielding connection portion 121 and contact the inner wall of the shielding connection portion 121 to support the shielding connection portion 121. Sealing contact surfaces are provided on the shielding supports 140 and 150 for contacting the first sealing member 131 to position the first sealing member 131 in the groove 101.

[0054] like Figures 5 to 7As shown in the illustrated embodiment, the aforementioned shielding supports 140 and 150 include an outer end cap 140 and a positioning seat 150. The outer end cap 140 is inserted into and snapped onto the shielding connection portion 121 of the shielding member 120. The positioning seat 150 is inserted into the shielding member 120 and held between the outer end cap 140 and the terminal support 112.

[0055] like Figures 5 to 7 As shown, in an exemplary embodiment of the present invention, a support portion may be provided on the radially inner side of the shielding connection portion 121 of the shielding member, the support portion being used to contact and cooperate with the shielding support members 140 and 150.

[0056] like Figures 5 to 7 As shown in the illustrated embodiment, the positioning seat 150 includes a positioning flange 152 that axially presses against the first seal 131 to position the first seal 131 in the groove 101. This restricts the axial displacement and deformation of the first seal 131, thereby improving the radial sealing performance of the first seal 131.

[0057] like Figures 5 to 7 As shown in the illustrated embodiment, a protrusion 140a is formed on the outer end cover 140, and a slot 121a is formed on the shielding connection portion 121 of the shielding member 120. The protrusion 140a is snapped into the slot 121a to snap the outer end cover 140 onto the shielding connection portion 121 of the shielding member 120.

[0058] like Figures 5 to 8 As shown, in the illustrated embodiment, allowable cables 10 are formed on the outer end cap 140, the positioning seat 150, and the terminal support 112, respectively (see Figure 112). Figure 8 The first through hole 141, the second through hole 151, and the third through hole 1121 are passed through. If there are multiple cables 10, multiple first through holes 141, multiple second through holes 151, and multiple third through holes 1121 need to be formed, and each cable 10 is inserted into the connector 100 through a corresponding set of through holes 141, 151, and 1121.

[0059] like Figures 5 to 8 As shown in the illustrated embodiment, the positioning base 150 further includes a first positioning portion 150a inserted into the first through hole 141 and a second positioning portion 150b inserted into the third through hole 1121. The second through hole 151 passes through the first positioning portion 150a and the second positioning portion 150b.

[0060] like Figures 5 to 7As shown in the illustrated embodiment, the connector 100 further includes a protective sleeve 160. This protective sleeve 160 is fitted onto the inner end portion 122 of the shield 120 and includes a radial extension for protecting the axial end face of the inner end portion. Furthermore, the protective sleeve 160 also serves to position the second seal 132. In the illustrated embodiment, a positioning step 111a is formed on the inner side of the outer peripheral wall 111 of the housing 110. The second seal 132 is axially positioned between the positioning step 111a and the end portion of the protective sleeve 160. This restricts the axial displacement and deformation of the second seal 132, thereby improving the radial sealing performance of the second seal 132.

[0061] like Figures 1 to 4 As shown, in an exemplary embodiment of the present invention, a connector assembly is also disclosed, which mainly includes: a connector 100 and a mating connector 200 adapted to mate with the connector 100. The mating connector 200 includes a mating housing 210 and a mating shield 220 installed in the mating housing 210.

[0062] like Figures 1 to 4 As shown in the illustrated embodiment, when connector 100 and mating connector 200 are mated together, mating shield 220 makes electrical contact with shield 120. In the illustrated embodiment, one end of mating shield 220 of mating connector 200 is adapted to be inserted into shield 120 of connector 100, and a first contact spring 221 adapted to make electrical contact with the inner surface of shield 120 is formed on one end of mating shield 220.

[0063] like Figures 1 to 4 As shown in the illustrated embodiment, a second contact spring 222 adapted for electrical contact with the housing of an electrical device (not shown) is formed at the other end of the mating shield 220. When the mating housing 210 of the mating connector 200 is mounted onto the housing of the electrical device, the second contact spring 222 of the mating shield 220 makes electrical contact with the housing of the electrical device. Thus, the outer shield 1 of the cable assembly can be electrically connected to the housing of the electrical device via the shield 120 and the mating shield 220.

[0064] like Figures 1 to 8 As shown, in another exemplary embodiment of the invention, a connector assembly is also disclosed, which includes a connector 100 and a cable assembly. Figure 8 As shown, the cable assembly mainly includes at least one cable 10 and an outer shield 1 fitted onto the at least one cable 10. The outer shield 1 of the cable assembly is electrically connected to the shield connection portion 121 of the shield 120 of the connector 100.

[0065] like Figure 8As shown, in the illustrated embodiment, the outer shield 1 of the cable assembly is a braided mesh shield, and this braided mesh shield can be bundled onto the shielding connection portion 121 of the shielding member 120. The cable 10 is a standard cable without a shielding layer. Figure 8 As shown, the cable 10 only includes a conductor core 11 and an outer insulation layer 12 wrapped around the conductor core 11, and does not include a shielding layer itself.

[0066] like Figures 5 to 8 As shown in the illustrated embodiment, in practical application, cable 10 is inserted into connector 100 and secured to connector 100 via a corresponding set of through holes 141, 151, 1121. Although not shown, in an exemplary embodiment of the invention, mating connector 200 further includes an insulating base (not shown) mounted in mating shield 220 and conductive terminals (not shown) mounted in the insulating base. When connector 100 and mating connector 200 are mated together, the conductive terminals in mating connector 200 are electrically connected to the conductor core 11 of cable 10 inserted into connector 100.
