Description

Cable electrical connector

The present invention relates to a cable electrical connector, in particular to a cable electrical connector with a grounding structure.

The transmission interface specifications of the cable electrical connector are quite diverse, such as HDMI, USB, TYPE-C, DP and so on. The cable electrical connector is plugged into the socket electrical connector and transmits signals through this, but the electronic device electrically connected to the cable electrical connector will be affected by electromagnetic interference (EMI) and electrostatic discharge (ESD) from time to time, resulting in electronic components damage.

In order to prevent electromagnetic interference (EMI) and electrostatic discharge (ESD) from damaging electronic components, the prior art usually connects the cable electrical connector with the socket electrical connector after the electrical cable connector is connected to the electrical socket connector. The metal casing is electrically connected, and the EMI (electromagnetic radiation) and ESD (static electricity) are drained to the metal casing and then discharged through the ground wire of the power cord of the electronic device to meet the product radiation and static electricity regulations.

The above-mentioned method of electrically connecting the metal housing and the cable electrical connector to ground is, for example, by adding a locking ground lug to the metal housing to electrically connect with the metal housing of the cable electrical connector, or adding conductive to the metal housing The foam is electrically connected to the metal shell of the cable electrical connector, but the above-mentioned methods require extra time for processing after the cable electrical connector is connected to the socket electrical connector, resulting in the consumption of labor costs and time costs for the user.

Therefore, one of the objectives of the present invention is to provide a cable electrical connector with a grounding structure to solve the above-mentioned problems.

Therefore, in some embodiments of the new type of cable electrical connector, it includes an insulating body, a plurality of terminals, a metal shell, and an elastic grounding member. The insulating body has a base and a projecting forward from the base. Plug-in part. The terminals are arranged in the insulating body, and some of the terminals are used as signal terminals, and some of the terminals are used as ground terminals. The metal shell covers the insulating body. The elastic grounding element is mechanically and electrically connected to the metal shell and extends forward from the metal shell in the same direction as the plug-in part, so that it can elastically expand and contract in a plug-in direction.

In some embodiments, the elastic grounding member is a metal elastic sheet.

In some embodiments, the elastic grounding member is a pogo pin.

In some embodiments, the cable electrical connector further includes an insulating housing, the insulating housing covers the metal housing and the elastic grounding member partially extends out of the insulating housing.

The present invention has at least the following functions: by electrically connecting the elastic grounding member 4 of the electric cable connector 100 of the present invention to the metal casing, the grounding effect can be conveniently achieved without the need for additional processes to make the electric cable connector The 100 is electrically connected to the metal casing to achieve the effect of saving labor and time costs.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numbers.

1 and 2, a first embodiment of the new cable electrical connector 100 of the present invention. The cable electrical connector 100 includes an insulating body 1, a plurality of terminals 2, a metal shell 3, and an elastic grounding member 4 , An insulating shell 5 and a cable 6.

In this embodiment, the cable electrical connector 100 is, for example, a cable electrical connector with transmission specifications such as HDMI (High Definition Multimedia Interface), DP (DisplayPort), USB, Type-C, Mini DP, Mini HDMI, etc. , But not limited to the above examples. The cable electrical connector 100 is used to electrically connect with a socket connector (not shown) to transmit signals.

The insulating body 1 has a base 11 and an insertion portion 12 protruding forward from the base 11 along an insertion square line P. The terminals 2 are provided in the plug-in portion 12 of the insulating body 1, and some of the terminals 2 are used as signal terminals and some of the terminals 2 are used as ground terminals, which are electrically connected to the corresponding terminals of the socket connector.

The metal shell 3 covers the insulating body 1. The elastic grounding member 4 is mechanically and electrically connected to the metal shell 3 and extends forward from the metal shell 3 in the same direction as the insertion portion 12, and can elastically expand and contract in the insertion direction P. In this embodiment, the elastic grounding member 4 is mechanically and electrically connected to the metal shell 3 by welding, and the elastic grounding member 4 is a spring pin with elasticity, but the above examples are not limited.

The insulating shell 5 covers the metal shell 3, for example, it can be made by insert molding or sleeve, but it is not limited to this. The elastic grounding member 4 partially extends out of the insulating shell 5.

The cable 6 has multiple transmission lines, and some of the transmission lines are used as signal transmission lines, and some of the transmission lines are used as ground transmission lines. The signal transmission lines of the cable 6 are electrically connected to the signal terminals, and the ground transmission lines are electrically connected to the signal terminals and the metal shell 3.

When the cable electrical connector 100 is mated with the socket connector, the elastic grounding member 4 can be elastically pressed against the metal casing where the socket connector is arranged to be electrically connected to the metal casing, that is, the cable can be electrically connected to the metal casing. The electrical connector 100 is grounded through the metal casing, and there is no need to add other processes to electrically connect the cable electrical connector 100 to the metal casing, so that the grounding effect can be easily achieved.

Referring to FIG. 3, a second embodiment of the cable electrical connector 100 of the present invention is similar to the first embodiment, except that the elastic grounding member 4 of the second embodiment is a resilient metal spring sheet.

In summary, by electrically connecting the elastic grounding member 4 of the cable electrical connector 100 of the present invention to the metal casing, the grounding effect can be conveniently achieved without the need for additional processes to make the cable electrical connector 100 and The metal casing is electrically connected to save labor and time cost.

However, the above are only examples of the present model, and should not be used to limit the scope of implementation of the present model, all simple equivalent changes and modifications made in accordance with the patent scope of the present model application and the contents of the patent specification still belong to This new patent covers the scope.
