Technical Field
[0001] This utility model relates to the field of connector technology, specifically to connectors for wire harness interfaces. Background Technology
[0002] HDMI (High-Definition Multimedia Interface) is a fully digital video and audio transmission interface that can send uncompressed audio and video signals. HDMI can be used in devices such as set-top boxes, DVD players, personal computers, televisions, game consoles, integrated amplifiers, digital audio systems, and televisions. HDMI can transmit audio and video signals simultaneously, and because audio and video signals use the same cable, it greatly simplifies system wiring installation.
[0003] During the transmission of audio and video signals, electromagnetic interference can directly affect the quality of the HDMI connector, thus impacting the user experience. Furthermore, the connection between the connector and the signal transmission cable is quite tight, making it difficult for users to quickly replace a damaged connector, which also affects their experience. Therefore, we propose a connector for cable harness interfaces. Utility Model Content

[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] 1. The connector for this wire harness interface, through the setting of a grounding ring and a spring, ensures that the grounding ring remains in contact with the equipment casing during use due to the spring's rebound force. This allows the connector to be grounded through the equipment casing, preventing external electromagnetic waves from affecting the internal signals of the connector and giving it a certain degree of anti-interference capability. Furthermore, the shielding ring further reduces the impact of external electromagnetic waves on the connector, improving its connection performance.
[0012] 2. The connector for this wire harness interface, through the setting of the wire fixing structure, allows the wire to be quickly fixed or separated from the connector, which facilitates the replacement of the connector and improves its practicality. In addition, the setting of the end of the shielding plate and the end of the fixed half ring being staggered improves the sealing performance of the wire fixing structure and facilitates the fixing of the wire.

[0018] 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.
[0019] Please see Figures 2 to 4 The connector for the wire harness interface includes a connector body 1. Limiting tubes 8 are welded to the middle of the left and right sides of the front end of the connector body 1. A spring 9 is welded to the middle of the inner cavity of the limiting tube 8. The other end of the spring 9 is welded to the grounding ring 2. The grounding ring 2 is in a movable sleeve state with the outer ring of the connector body 1. Through the setting of the grounding ring 2 and the spring 9, the position of the grounding ring 2 can be deformed. During the connection of the connector with the equipment, the grounding ring 2 will be squeezed by the equipment shell. Under the action of the spring 9, the grounding ring 2 can fit tightly with the equipment shell, which can reduce the influence of external electromagnetic waves on the connector and facilitate signal transmission.
[0020] The middle of the left and right ends of the grounding ring 2 is provided with a movable groove. The limiting tube 8 is movably connected to the inner cavity of the movable groove. A limiting block is welded to the outer side of the limiting tube 8 near the end of the grounding ring 2. A limiting groove adapted to the limiting block is provided on the outer side of the inner cavity of the movable groove. When the spring 9 does not deform, the limiting block contacts the rear end of the limiting groove. The setting of the limiting block can play a limiting role and prevent the grounding ring 2 from separating from the connector body 1.
[0021] A shielding ring 11 is embedded in the middle of the side wall of the connector body 1. The shielding ring 11 is made of conductive rubber. By setting the shielding ring 11, the shielding ring 11 can reduce the influence of external electromagnets on the internal signal of the connector, which can further enhance the performance of the connector and facilitate its use.
[0022] Please see Figure 1 and 3 The connector body 1 has a wire groove in the middle of its rear end. The wire groove facilitates the contact between the wire and the components inside the connector body 1. The wire groove also has a wire fixing structure on its rear side. The wire fixing structure allows the wire to be quickly fixed or separated from the connector body 1, which facilitates the replacement of the connector or the wire and improves the practicality of the connector.
[0023] The wire fixing structure includes a fixed half-ring 3 and a movable half-ring 4 adapted to the fixed half-ring 3. One end of the fixed half-ring 3 is welded to the connector body 1. Shielding plates 6 are fixedly connected to the inner walls of both the fixed half-ring 3 and the movable half-ring 4. The shielding plates 6 are made of conductive rubber. Sealing plates 7 are fixedly connected to the inner walls of the shielding plates 6. Sealing plates 7 are made of silicone. The ends of the shielding plates 6 and the sealing plates 7 are offset from the ends of the fixed half-ring 3 and the movable half-ring 4. By setting the positions of the shielding plates 6 and the sealing plates 7, the sealing performance between the wire fixing structure and the wire can be improved, making it easier to fix the wire to the connector.
[0024] The fixed half-ring 3 and the movable half-ring 4 are made of magnets. Both ends of the fixed half-ring 3 and the movable half-ring 4 are provided with sliding grooves 10. A connecting ring 5 is movably connected in the inner cavity of the sliding groove 10. The fixed half-ring 3 and the movable half-ring 4 can be connected together through the connecting ring 5. The connecting ring 5 is made of iron, and the outer surfaces of the connecting ring 5, the fixed half-ring 3 and the movable half-ring 4 are covered with silicone pads. A protrusion is connected in the middle of the connecting ring 5. The protrusion facilitates the movement of the connecting ring 5, that is, the fixed half-ring 3 and the movable half-ring 4 can be quickly fixed or separated, which facilitates the fixing or separation of the wire from the connector.
[0025] Working principle: During use, when the connector is connected to the equipment, the grounding ring 2 is squeezed by the equipment shell, and the spring 9 is in a compressed state. The grounding ring 2 and the equipment shell can fit tightly, so that the connector has the function of grounding, eliminating the influence of external electromagnetic waves on the internal signal of the connector, facilitating signal transmission. When it is necessary to separate the wire from the connector body 1, the user pulls the connecting ring 5 outward. After the connecting ring 5 separates from the fixed half ring 3 and the moving half ring 4, the user pulls the moving half ring 4 upward. The moving half ring 4 can be quickly separated from the wire, which facilitates the separation of the wire from the connector body 1.

Although embodiments of this utility model 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 this utility model.
