Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, and in particular to a shielding structure for a connector and a connector. Background Technology
[0002] A shielding structure is a special structure used in connector design to reduce or eliminate the impact of external electromagnetic interference on the internal signal transmission of the connector. Through a well-designed shielding structure, the connector can ensure stable and reliable signal transmission in various complex electromagnetic environments.
[0003] A common shielding structure in the prior art can be found in the elastic conductive member used in the cable connector disclosed in Chinese invention patent application CN117937147A. The elastic conductive member includes a cover and a pressing part. The cover is configured to cover a braided sleeve supported by a generally arc-shaped section in the middle of the cable support part. The generally arc-shaped section supports a portion of the outer periphery of the braided sleeve through its inner surface.
[0004] The shielding structure (elastic conductive member) in the invention patent application CN117937147A is a slide-in type shielding cover. This installation method is relatively simple and convenient, but it has certain potential problems in terms of stability. For example, when assembling the connector, various operations are involved, such as insertion, removal, and twisting. Since the shielding structure is slide-in and the wire harness direction is not fixed, the forces generated by these operations can easily cause the shielding structure to detach from its original installation position, resulting in the shielding structure falling off or becoming misaligned. Moreover, the shielding structure can only be fixed after the connector is fully installed, which requires operators to spend more effort to restrict the position of the shielding structure during the assembly process. Utility Model Content
[0005] The first technical problem to be solved by this utility model is to provide a shielding structure for a connector that can be pre-fixed during the assembly process, in contrast to the above-mentioned prior art.
[0006] The second technical problem to be solved by this utility model is to provide a connector with the above-mentioned shielding structure in contrast to the prior art.
[0007] The technical solution adopted by this utility model to solve the first technical problem is: a shielding structure for a connector, characterized in that it includes a first shielding shell and a second shielding shell spaced apart, both of which are axially hollow and are used to respectively wrap around the outside of different wire bundles, the first shielding shell and the second shielding shell are connected by a connecting part located between them, and an anti-rotation structure is provided on the connecting part.
[0008] Specifically, the axial direction of the first shielding shell is parallel to the axial direction of the second shielding shell, and the plane located on the connecting part for connecting the two shielding shells is perpendicular to the axial direction of either shielding shell.
[0009] Preferably, the anti-rotation structure is an anti-rotation latch formed on the connecting part, which is used to cooperate with the anti-rotation latch strip of the connector.
[0010] To further prevent the shielding structure from rotating, preferably, the connecting part has four anti-rotation slots, each anti-rotation slot is strip-shaped, and the four anti-rotation slots are distributed around the center of the connecting part at intervals, and the strip-shaped anti-rotation slots radiate outward from the center.
[0011] Furthermore, the width of the strip-shaped anti-rotation slot gradually increases outward from the axis.
[0012] To facilitate the alignment and installation of the anti-rotation bayonet with the anti-rotation strip of the connector, preferably, a positioning hole is provided on the connecting part at the center position of the axis around which the anti-rotation bayonet surrounds. This positioning hole is used to cooperate with the positioning protrusion of the connector.
[0013] Preferably, a contact spring is formed on the connection portion and extends along the wire inlet direction, the contact spring being used to contact the plug housing of the connector.
[0014] To limit the forward and backward displacement of the wire bundle, preferably, the inner side of the first shielding shell and the inner side of the second shielding shell are both formed with wire clamping springs extending inward along their respective tangential directions. The wire clamping springs are used to press down and limit the corresponding wire bundles.
[0015] The technical solution adopted by this utility model to solve the first technical problem is: a connector, characterized in that it uses the shielding structure of the connector described in any one of the above.
[0016] To prevent forward displacement of the shielding structure during assembly, the connector further includes a plug and a socket that are assembled with each other. The plug includes a tail connection housing for wire entry, which has two parallel wire entry channels. The first shielding housing and the second shielding housing of the connector's shielding structure are respectively disposed in their respective corresponding wire entry channels. Limiting ribs are provided on the front side of both wire entry channels, and the limiting ribs limit the shielding housing within the corresponding wire entry channel.
[0017] Compared with the prior art, the advantages of this utility model are:
[0018] Firstly, this invention optimizes the slide-in mounting shielding cover structure into a shielding structure where a first shielding shell and a second shielding shell are connected. The first and second shielding shells are connected by a connecting part, which is equipped with an anti-rotation structure. This effectively prevents the shielding structure from rotating during connector assembly due to insertion, removal, twisting, or other operations.
[0019] In addition, the present invention also provides a limiting rib on the front side of the incoming line channel. The limiting rib can restrict the forward movement of the first shielding shell and the second shielding shell. In addition, the connecting part itself abuts against the front side of the tail connecting shell. That is to say, the tail connecting shell restricts the backward movement of the connecting part. Therefore, the displacement of the entire shielding structure in the front and rear directions is restricted. The present invention achieves the pre-fixation of the shielding structure during assembly. Attached Figure Description

[0025] Figure 6 for Figure 1 The connector shown is a cross-sectional view. Detailed Implementation
[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0027] like Figures 1-6 The diagram shows a preferred embodiment of the shielding structure and connector of this utility model.
[0028] Please refer to Figure 1 The connector in this embodiment includes a plug 1 and a socket 2 that are assembled with each other. The plug 1 includes a tail connection housing 11. A wire harness passes through the tail connection housing 11 and connects to the inside of the plug 1. A shielding structure 12 for electromagnetic interference is provided inside the tail connection housing 11.
[0029] like Figure 2As shown, the tail connection housing 11 has two parallel inlet channels 111. Correspondingly, the shielding structure 12 has a first shielding housing 121 and a second shielding housing 122 respectively disposed in the two inlet channels 111. The first shielding housing 121 and the second shielding housing 122 are both axially hollow and respectively wrap around the outside of the wire bundle in the corresponding inlet channel 111.
[0030] Both incoming cable channels 111 are equipped with limit ribs 114 on their front sides. Please refer to [reference needed]. Figure 2 and Figure 5 The limiting rib 114 confines the first shielding shell 121 and the second shielding shell 122 within their respective incoming line channels 111.
[0031] The axial direction of the first shielding shell 121 is parallel to the axial direction of the second shielding shell 122. The first shielding shell 121 and the second shielding shell 122 are connected by a connecting portion 126 located between them. The plane located on the connecting portion 126 and used to connect the two shielding shells is perpendicular to the axial direction of either shielding shell. The connecting portion 126 is provided with an anti-rotation structure, thereby effectively preventing the shielding structure 12 from rotating due to insertion, removal, twisting, or other operations during connector assembly. The limiting rib 114 can limit the forward movement of the first shielding shell 121 and the second shielding shell 122. In addition, the connecting portion 126 itself abuts against the front side of the tail connecting shell 11, that is, the tail connecting shell 11 restricts the backward movement of the connecting portion 126. Therefore, the displacement in the front-rear direction and the rotation in the circumferential direction of the entire shielding structure 12 are restricted, thereby achieving pre-fixation of the shielding structure 12 during assembly.
[0032] like Figure 3 and Figure 4 As shown, in this embodiment, the anti-rotation structure is an anti-rotation latch 124 formed in the connecting part 126. The tail connecting housing 11 has a corresponding anti-rotation latch 112, which can be inserted into the anti-rotation latch 124 to prevent the shielding structure 12 from rotating. The anti-rotation latch 124 is strip-shaped, and there are four of them. The four anti-rotation latches 124 are distributed around the center of the connecting part 126 at intervals, and the strip-shaped anti-rotation latches 124 radiate outward from the axis. The width of the strip-shaped anti-rotation latch 124 gradually increases from the axis outward, and the anti-rotation latch 112 is also set as a corresponding wedge shape.
[0033] Please continue to refer to this. Figure 3 and Figure 4 To facilitate the alignment and installation of the anti-rotation latch 124 with the anti-rotation latch strip 112 of the connector, a positioning hole 125 is provided on the connecting part 126 at the axis position surrounding the anti-rotation latch 124, and a positioning protrusion 113 is provided on the tail connecting housing 11 to cooperate with the positioning hole 125. The positioning protrusion 113 can pass through the positioning hole 125.
[0034] On the connecting portion 126, a contact spring 123 extends along the wire inlet direction and forms a contact spring 123. The contact spring 123 is used to contact the plug housing 13 of the connector, thereby fully realizing the shielding function of the shielding structure 12. Figure 6 As shown.
[0035] In addition, to limit the forward and backward displacement of the wire harness, such as Figure 3 As shown, the first shielding housing 121 and the second shielding housing 122 each have a wire clamping spring 127 extending tangentially inward within their respective housings. The wire clamping spring 127 is used to clamp and restrict the corresponding wire bundle. The wire clamping spring 127 is bent along the wire inlet direction, so when the wire bundle passes through, it will be clamped by the wire clamping spring 127 and will not easily come out, but when it enters, it will not be excessively restricted by the wire clamping spring 127.
