Description

Wire end cable connector improved structure

The present invention relates to a connector module related technology, and particularly relates to an improved structure of a cable end cable connector with fast assembly and good electromagnetic interference prevention effect.

According to the coaxial cable, the signal transmission of various electronic products is widely used. As the electronic product develops toward miniaturization, the size of the connector for the coaxial cable inside the electronic product is also required to be greatly reduced.

The general line end connector should be connected to the coaxial cable. For example, the electrical connector of the Republic of China Announcement No. 579110 mainly crimps the coaxial cable into the crimping groove provided in the terminal portion and is fixed through the outer casing. However, the conventional structure has the following disadvantages: (1) Since the coaxial cable has a relatively small wire diameter, the position and precision of the combination through the crimping are relatively low, which greatly reduces the yield of the product; (2) the coaxial cable only passes through the outer casing and the pressure. The groove is fixed easily and loosened, and the subsequent unnecessary heavy work program is derived.

The main purpose of the improved cable end connector of the present invention is to provide a connecting end in the shielded lower casing. When the coaxial cable is combined in the insulating base, the metal grounding layer of the coaxial cable is connected by welding. The shielded lower case is joined, whereby the assembly process can be simplified and the coaxial cable can be fixed at the same time.

A structure that can achieve the above object includes: an insulating base, at least one An upper end terminal, at least one coaxial cable, a shielded lower casing, and a shield upper casing; the insulating base is provided with a body, the body is provided with a slot and a mating slot, the slot and the mating A fixing portion is disposed between the slots, the fixing portion is configured to fix the wire end terminals, such that the wire terminal ends are fixed to the slot, the other side is fixed to the mating slot, and the wire end terminals are closely connected The side of the slot is formed with a contact portion; the coaxial cable is sequentially provided with a conductor, an inner insulating layer, a metal ground layer and an outer insulating layer from the inside to the outside, and the guiding system penetrates the shielding upper casing; The shielding lower casing and the shielding upper casing are used for covering the insulating base, wherein the shielding lower casing is provided with one or more bent connecting ends corresponding to one side of the matching groove.

By the way, the conductor of the coaxial cable is soldered to the contact portion of the wire terminal, and the metal ground layer is soldered to the connection end of the shielded lower casing, thereby completing the electrical connection between the coaxial cable and the terminal, and the coaxial cable. The electrical connection is made with the grounding of the shielded lower case. Therefore, the present invention has the advantages of being easy to manufacture and assemble, and having good anti-electromagnetic interference effect.

In the embodiment of the present invention, a plurality of fastening protrusions are disposed on the two sides of the main body, and the shielding lower housing is provided with a plurality of fastening slots corresponding to the fastening protrusions. The engaging protrusions are fastened to the fastening slots, so that the insulating base is combined with the shielding lower casing; the assembly personnel do not need to use a combination bolt such as a screw, and the assembly is quite fast and convenient.
