Description

Technical Field

[0001] This utility model relates to the field of electronic connector technology, and in particular to an anti-interference electronic connector. Background Technology

[0002] Electronic connectors, also known as circuit connectors or electrical connectors, are conductor devices that bridge two conductors in a circuit, allowing current or signals to flow from one conductor to the other. An electronic connector is a type of electrical system that provides a separable interface for connecting two secondary electronic systems. Simply put, a connector is a component used to complete the electrical connection between circuits or electronic machines, i.e., a bridge between the two.

[0003] Electronic connectors are widely used in daily life. However, existing electronic connectors have problems such as insufficient suppression of high-frequency interference by traditional single-layer shielding structures in complex electromagnetic environments, and easy distortion of signal transmission. Therefore, we propose an anti-interference electronic connector. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide an anti-interference electronic connector to solve the technical problem that the traditional single-layer shielding structure is insufficient in suppressing high-frequency interference and the signal transmission is prone to distortion.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] An anti-interference electronic connector includes a metal alloy shielding shell, a composite shielding layer structure mounted on the metal alloy shielding shell, a four-pin contact mounted on the metal alloy shielding shell, and the composite shielding layer structure surrounding the four-pin contact.

[0008] A rubber pad, wherein the rubber pad has a fitting hole adapted to the metal alloy shielding shell, and the rubber pad is fitted onto the metal alloy shielding shell through the fitting hole;

[0009] A cross-shaped connecting bolt is installed through the metal alloy shielding shell and the rubber pad.

[0010] As an improved technical solution, the metal alloy shielding shell has an integrally formed edge plate that fits onto the outer surface of the metal alloy shielding shell. The edge plate has a first through hole at each of its four corner edges that corresponds to the cross connecting bolt. The cross connecting bolt is adapted to the first through hole so that the cross connecting bolt can be installed through the metal alloy shielding shell.

[0011] As an improved technical solution, the rubber pad has a second through hole at each of its four corner edges, corresponding to the cross-shaped connecting bolt. The second through hole is adapted to the cross-shaped connecting bolt. The cross-shaped connecting bolt passes through the metal alloy shielding shell and the rubber pad through the first through hole and the second through hole, so that the cross-shaped connecting bolt can be installed on the rubber pad and the metal alloy shielding shell, thereby facilitating the fixing of the electronic connector using the cross-shaped connecting bolt.

[0012] As an improved technical solution, the composite shielding layer structure includes an outer magnetic permeability shielding layer, an intermediate conductive isolation layer, and an inner electromagnetic absorption layer, so as to suppress high-frequency interference and prevent signal transmission from being easily distorted.

[0013] As an improved technical solution, the outer surface of the four-pin contact is plated with a gold-palladium alloy composite coating to improve the stability of the contact force and extend the service life of the four-pin contact during insertion and removal.

[0014] As an improved technical solution, the inner wall of the metal alloy shielding shell is provided with multiple guide grooves for preventing misinsertion, and the multiple guide grooves are not equidistant along the axial / circumferential direction of the metal alloy shielding shell to prevent misinsertion.

[0015] As an improved technical solution, the outer surface of the metal alloy shielding shell is provided with external threads for locking, so as to facilitate locking connection.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. This utility model, by setting a composite shielding layer structure consisting of an outer magnetic permeability shielding layer, an intermediate conductive isolation layer and an inner electromagnetic absorption layer, can suppress high-frequency interference and prevent signal transmission from being easily distorted.

[0018] 2. This utility model improves the stability of contact force and extends the service life of the four-pin contact by plating a gold-palladium alloy composite coating on the surface of the four-pin contact.

[0019] 3. This utility model, by setting non-equidistant guide grooves on the metal alloy shielding shell, can prevent mis-insertion and improve the convenience of plugging and unplugging electronic connectors. Attached Figure Description
