Thinned electrical connector structure

The present invention relates to an electrical connector structure, and in particular to a thinned electrical connector structure.

With the advancement of the information electronics industry, portable electronic devices are becoming more and more popular. Some portable electronic devices, such as the commonly known flash drive, thumb USB disk, etc., these electronic devices are usually connected to the host end (such as a personal computer or a notebook computer) through a specific data transmission interface for data transmission, which is The Serial Serial Bus (USB) interface is the most common. Therefore, many portable electronic devices adopt USB as a transmission interface, and the advantage is that the use of USB as a transmission interface can have greater compatibility with current computer systems.

The conventional USB socket connector and the circuit board are combined by soldering or the like to realize circuit connection. However, limited by the thickness and structure of the existing USB connector housing, the electronic device to which the USB connector is applied is thicker and less portable. At present, the existing USB part plug structure has also been changed, and the metal casing is removed from the joint portion of the socket connector. As shown in FIG. 6, the current key-shaped thin U disk 6 and the commonly used thin plug 8 have a plug portion. Both 60 and 80 have been structurally simplified. The plug-in portions are exposed, and a plurality of contact points 61, 81 are disposed thereon. When the plug-in portions 60, 80 are respectively plugged and coupled with the USB receptacle connector 10, only the space between the bottom wall 103 of the connector metal case and the tongue portion 102 is occupied, and data transmission can be realized, and at this time, the tongue portion is realized. The space between 102 and the top wall 101 of the metal casing is idle. As a result, the trend toward thinning portable electronic devices using the USB receptacle connector is limited.

In view of this, it is indeed necessary to improve the structure of the prior art USB socket connector to solve the above drawbacks.

The main purpose of this creation is to provide a thinned electrical connector structure to reduce The electrical connector space occupancy makes the portable electronic device to which the electrical connector is applied thinner.

The present invention mainly provides a thinned electrical connector structure, comprising an insulating body, a plurality of conductive terminals fixed to the insulating body, and a metal casing, wherein the insulating system extends forward to form a tongue and is at the tongue A plurality of channels are arranged, the conductive terminals are fixed on the insulating body, and each of the conductive terminals is provided with a resilient contact portion suspended in the channel, and the metal shell has a top wall, a bottom wall and two connecting the top wall and the bottom wall The sidewall is sleeved on the periphery of the insulative housing, and the tongue of the insulative housing is attached to the bottom wall of the metal casing, and the top wall, the side wall and the tongue portion together form a receiving space, and the elastic contact portion protrudes from the receiving space.

The authoring connector reduces the overall height of the connector by bonding the tongue of the insulating body to the bottom wall of the metal casing, thereby achieving the development of thinning.

The above-mentioned objects, advantages and features of the present invention will be described in detail in the following description of the preferred embodiments.

Referring to the first figure, a thinned electrical connector 5 structure includes an insulative housing 1, a plurality of conductive terminals 2 fixed to the insulative housing 1, and a metal housing 3. The insulative housing 1 has a main body portion 12 and a tongue portion 11 formed by the front portion of the main body portion 12. The tongue portion 11 is provided with a plurality of channels 14 which are vertically penetrated and the main body The portion 12 is provided with a plurality of channels 13 corresponding to each of the channels 14 for the conductive terminals 2 to be fixed. At the same time, a card slot 15 is provided on both sides of the main body portion 12 of the insulative housing 1, and the metal casing 3 is thereby fixed to the metal casing 3.

Each of the conductive terminals 2 is provided with a fixing portion 21, and is bent forwardly at the fixing portion 21 to form an elastic contact portion 22, and is bent backward to form a welded portion 23.

The metal casing 3 defines a top wall 31, a bottom wall 35, and two side walls 33 connecting the top wall 31 and the bottom wall 35. The bottom wall 35 is provided with at least one through hole 36 corresponding to each channel 14, which is implemented in the present invention. In the example, the through holes 36 are plural. When the metal casing 3 is sleeved on the insulative housing 1, each of the channels 14 has a wider space in the upper and lower spaces, and is more spacious when the elastic contact portion 22 is elastically resisted and displaced up and down. Space. The side walls 33 of the metal casing 3 are horizontally bent and extended to form the soldering legs 34, so that the connector is soldered and fixed to the circuit board 4 (as shown in the fourth figure), and the sidewalls 33 are torn to form the barbs 37 for metal. The outer casing 3 is fixedly sleeved on the insulating body 1 slot 15 . The metal casing 3 is provided with a plurality of dome-shaped protrusions 32 extending into the inner side of the top wall 31 to provide a clamping force for the mating plug connector (not shown) to be inserted into the connector.
