Description

Technical Field

[0001] This utility model belongs to the field of automotive connector technology, specifically a shielding cover structure for automotive connectors. Background Technology

[0002] With the increasing level of automotive electronics, connectors are playing an increasingly important role in automotive electrical systems. As an indispensable component of electronic devices, connectors primarily ensure reliable connections between circuits and transmit current or signals. Automotive connectors typically have shielding covers, whose main function is to prevent electromagnetic interference, ensure the stability and reliability of signal transmission, protect internal components from external environmental damage, extend the connector's lifespan, and improve its performance. In existing technologies, automotive connector shielding covers often suffer from problems during installation and use, such as insecure connections between the insulating inner shell and the shielding cover, and difficulty in inserting external plugs, leading to unstable signal transmission or connector damage. To address this, we propose a new automotive connector shielding cover structure. Utility Model Content

[0003] The purpose of this utility model is to provide a shielding cover structure for automotive connectors, which can effectively ensure a reliable connection between the insulating inner shell and the shielding cover shell, and provide effective guidance for the insertion of external plugs, thereby improving the performance of the product.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model provides a shielding cover structure for an automotive connector, including an insulating inner shell, an outer shielding cover shell, and an upwardly curved connecting plate around the bottom of the shielding cover shell. A connecting collar is fitted onto the outer bottom of the shielding cover shell, and the connecting collar engages with the gap between the connecting plate and the shielding cover shell. A connecting buckle plate connected to the connecting collar is fixed to the bottom of the insulating inner shell. A plug sleeve is fixed to the upper end of the insulating inner shell, and an installation hole for the plug sleeve to pass through is formed on the shielding cover shell. The plug sleeve has a hollow cavity, and an outwardly expanding guide port is formed at the upper end of the plug sleeve, with the outer side of the guide port closely attached to the edge of the installation hole.

[0006] Preferably, the insulating inner shell has a clearance hole on its side, and the shielding cover shell has an elastic buckle plate connected to the insulating inner shell and an elastic contact plate corresponding to the position of the clearance hole on its side.

[0007] Preferably, the shielding cover housing, the elastic buckle plate, and the elastic contact plate are integrally formed. The insulating inner shell is provided with a slot suitable for engaging with the elastic buckle plate. The clearance hole penetrates the side wall of the insulating inner shell, and the end of the elastic contact plate extends into the interior of the insulating inner shell through the clearance hole.

[0008] Preferably, the mounting hole has a downwardly protruding limiting flange at its edge, and the outer side of the guide port is in close contact with the limiting flange.

[0009] Preferably, the insert and the insulating inner shell are snap-fitted together, the insulating inner shell and the two connecting buckles are injection molded as one piece, and the outer edges of both ends of the connecting collar are respectively engaged with the two connecting buckles.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model optimizes the design of the shielding cover structure of the automotive connector. Specifically, a connecting collar is installed on the outer side of the bottom of the shielding cover housing, and a connecting buckle is provided at the lower end of the insulating inner shell. The connecting buckle is fixedly connected to the connecting collar. In addition, by setting a plug sleeve and providing an outwardly expanding guide port at the upper end of the plug sleeve, the outer side of the guide port is closely attached to the edge of the mounting hole. This not only provides effective guidance when the external plug is inserted into the insulating inner shell, but also strengthens the connection between the insulating inner shell and the shielding cover housing through the plug sleeve. This effectively ensures the reliability of the connection between the shielding cover housing and the insulating inner shell and guarantees its performance. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1 to 4 As shown, the automotive connector shielding structure in this embodiment of the present invention includes an insulating inner shell 2, and a shielding shell 1 is mounted on the outside of the insulating inner shell 2. The bottom of the shielding shell 1 has upwardly curved connecting plates 11 around its perimeter. A connecting collar 3 is fitted onto the outer bottom of the shielding shell 1, and the connecting collar 3 engages with the gap between the connecting plates 11 and the shielding shell 1, thereby ensuring an effective connection between the connecting collar 3 and the shielding shell 1. A connecting buckle plate 4 is fixed to the bottom of the insulating inner shell 2, and the two connecting buckle plates 4 are respectively connected to both ends of the connecting collar 3. A plug sleeve 8 is fixed to the upper end of the insulating inner shell 2. The shielding shell 1 has a mounting hole 7 for the plug sleeve to pass through. The plug sleeve 8 has a hollow cavity, and an outwardly expanding guide is formed at the upper end of the plug sleeve 8. The guide port 81, or guide port 1, is flared, with its outer side closely attached to the edge of the mounting hole 7. In this embodiment, the structure of the automotive connector shield is optimized. Specifically, a connecting collar 3 is installed at the bottom of the outer side of the shield housing 1, and a connecting buckle 4 is provided at the lower end of the insulating inner shell 2. The connecting buckle 4 is fixedly connected to the connecting collar 3. In addition, a plug sleeve 8 is provided, and an outwardly expanding guide port 81 is provided at the upper end of the plug sleeve 8. The outer side of the guide port 81 is closely attached to the edge of the mounting hole 7. This provides effective guidance when the external plug is inserted into the insulating inner shell 2, and also strengthens the connection between the insulating inner shell 2 and the shield housing 1 through the plug sleeve 8. This effectively ensures the reliability of the connection between the shield housing 1 and the insulating inner shell 2 and guarantees its performance.

[0019] Furthermore, the insulating inner shell 2 has a clearance hole 20 on its side, and the shielding shell 1 has an elastic buckle plate 6 connected to the insulating inner shell 2 and an elastic contact plate 5 corresponding to the position of the clearance hole 20 on its side; the elastic buckle plate 6 is adapted to snap onto the insulating inner shell 2; by providing a clearance hole 20 on the side of the insulating inner shell 2 and designing an elastic buckle plate 6 and an elastic contact plate 5 on the side of the shielding shell 1, a stable connection between the shielding shell 1 and the insulating inner shell 2 is achieved, preventing loosening caused by vibration or external force.

[0020] Combination Figure 1 and Figure 3The shielding housing 1, the elastic buckle plate 6, and the elastic contact plate 5 are integrally formed. The insulating inner shell 2 is provided with a slot suitable for engaging with the elastic buckle plate 6. The slot and the elastic buckle plate 6 cooperate to achieve a reliable engagement. The clearance hole 20 penetrates the side wall of the insulating inner shell 2. The end of the elastic contact plate 5 extends into the interior of the insulating inner shell 2 through the clearance hole 20 to be suitable for direct connection with the internal shielding components, ensuring the continuity of the shielding effect and the stability of signal transmission.

[0021] See Figure 2 To better accommodate the connection between the edge of the mounting hole 7 and the sleeve 8, a downwardly protruding limiting flange 71 is formed on the edge of the mounting hole 7. The outer side of the guide port 81 is tightly attached to the limiting flange 71, so that the guide port 81 can be recessed into the shielding housing 1, thereby ensuring the flatness of the shielding housing 1. This design not only optimizes the tightness of the connection between the sleeve 8 and the shielding housing 1, but also avoids interference or unsightly appearance problems that may be caused by the exposed guide port 81, further improving the overall performance and aesthetics of the product.

[0022] To facilitate the connection between the insert 8 and the insulating inner shell 2, the insert 8 and the insulating inner shell 2 are designed to snap together. The insulating inner shell 2 and the two connecting buckles 4 are integrally formed by injection molding to ensure the integrity and strength of the structure. The outer edges of both ends of the connecting collar 3 are respectively connected to the two connecting buckles 4. The connecting buckles 4 are preferably "7" plates. The connecting buckles 4 are hooked on the outer edge of the connecting collar 3. This design not only achieves a firm positioning of the connecting buckles 4 and the connecting collar 3, but also facilitates loading and unloading. At the same time, it optimizes the load-bearing capacity and vibration resistance of the structure, ensuring the long-term stable operation of the product.
