Abstract

This invention concerns an electric connector, which comprises the metal casing with splinter, the insulator, and the signal terminal. The metal casing is wrapped around the insulator. In the middle of the insulator is a slot. The front end of the signal terminal is inserted into the slot. The splinter is inside the slot and wrapped around the connecting plate outside the insulator. The splinter is the metal casing formed from the random curve on at least one side of the two sides of the slot. The upper and lower sides of the metal casing have at least one soldering foot. The rear end of the soldering foot protrudes the metal casing and is in line with the rear end of the signal terminal. This invention provides an integral splinter and a metal casing, which effectively strengthens the connection of the slot and the socket, and facilitates the assembly by saving grounding components. In addition, the entire structure is more intact with better strength, and is of low cost, user-friendly, and has higher reliability.

Description

Electrical connector

The invention is an electrical connector, especially an electrical connector for computers, household appliances, digital electronic products and the like.

LVDS interface (low voltage differential signal interface) is widely used in motherboards of LCD screens for computers, communication equipment, consumer electronics (such as various types of liquid crystal displays, LCD screen computers, LCD TVs, cameras, etc.). It features ultra-low voltage swing and high-speed differential transmission data, which can realize point-to-point or point-to-multipoint connection. It has the advantages of low power consumption, low bit error rate, low crosstalk and low radiation. Therefore, the application of LVDS is increasingly widely. At present, such connectors on the market have the following disadvantages: the grounding terminal (mask terminal) requires a separate component, such as the Chinese utility model patent of application number 201120331577.2, which is provided with a separate grounding terminal, so it is not easy to assemble; The total surface roughness of the tin feet is not easy to control, the solder joints are prone to up and down, resulting in unstable soldering; the connection between the plug and the socket is not strong enough, which may cause poor contact.

SUMMARY OF THE INVENTION A primary object of the present invention is to provide an electrical connector that is robust, reliable in construction, easy to assemble, and less costly.

In order to achieve the above object, the technical means adopted by the electrical connector of the present invention comprises a metal casing with a connecting elastic piece, an insulator and a signal terminal, the metal casing is covered on the insulator, the socket is in the insulator, and the front end of the signal terminal is inserted into the socket. In the slot, the elastic piece is located in the slot and is covered with the outer connecting plate of the insulator; the elastic piece is formed by bending the metal shell at any position on the upper and lower sides of the slot, at least one place; metal At least one soldering leg protrudes from any position on the upper and lower sides of the outer casing, and a portion of the rear end of the soldering foot projecting from the metal outer casing is aligned with the rear end portion of the signal terminal.

Further, the metal casing is bent at one side of the slot to the inside of the slot to form at least one U-shaped hook, and the other side of the metal casing at the slot is bent toward the inside of the slot to form at least one The 7-shaped hook is attached; the U-shaped hook and the 7-shaped hook are bent toward each other; the U-shaped hook and the 7-shaped hook are respectively fastened to the upper and lower sides of the insulator. This prevents the plastic insulator from warping when the solder plate is too hot.

Further, an end hook is formed by bending at at least one end of the metal casing. In this way, the soldering feet of both ends can be prevented from rising and falling, and the metal shell feet can be prevented from being soldered when the soldering plate is too high.

The utility model has the beneficial effects that: firstly, the elastic piece and the metal outer casing are integrally formed, which effectively enhances the connection firmness after the plug and the socket are butted, and the metal outer casing is used as the grounding component, thereby saving the grounding parts and being easier to assemble; Second, the overall structure is more stable and stronger; third, lower cost, more convenient to use, and higher reliability.

Referring to FIG. 1 , FIG. 2 , FIG. 3 , FIG. 4 and FIG. 5 , the electrical connector of the embodiment is a socket, and the electrical connector of the present invention comprises a metal casing with an elastic piece, an insulator, a signal terminal and a spring 11 . The metal casing is covered on the insulator, the insulator is a slot, the front end of the signal terminal protrudes into the slot, the elastic piece 11 is located in the slot and covers the outer connecting plate of the insulator; the elastic piece 11 is a metal casing located at the slot of the slot The lower side (which may also be the upper side) is bent at any position, and the number of the bent portions is at least one; the upper side of the metal casing (which may also be the lower side) protrudes at least one of the welding legs 21 at any position. The portion where the rear end of the soldering foot 21 protrudes from the metal case is identical in structure to the rear end portion of the signal terminal and is aligned with each other. In this way, when the plug 1 is inserted into the socket 2, the insertion force is increased, and the connection stability after the docking is effectively enhanced.

Referring to Figures 1, 2 and 6, the metal casing is bent at the side of the slot toward the inside of the slot to form at least one U-shaped hook 41, and the other side of the metal casing is located at the slot opening. The inner portion of the groove is formed with at least one 7-shaped hook 31; the U-shaped hook 41 and the 7-shaped hook 31 are bent toward each other; the U-shaped hook 41 and the 7-shaped hook 31 respectively catch the upper and lower sides of the insulator. This prevents the plastic insulator from warping when the solder plate is too hot.

Referring to Figures 1 and 5, an end hook 51 is formed by bending at least one end of the metal casing. In this way, the soldering feet of both ends can be prevented from rising and falling, and the metal shell feet can be prevented from being soldered when the soldering plate is too high.

The present invention has been described in detail above, and the foregoing is only a preferred embodiment of the present invention, and the scope of the present invention is not limited, and all changes and modifications according to the scope of the present application should still be The scope of the invention is covered.
