Description

Micro connector

The utility model relates to a kind of micro connector, is meant a kind of ultra-thin micro connector that the circuit board arrangement space can be guaranteed its structural strength again of saving especially.

The development that electronics technology is maked rapid progress has made present electronic product, compact day by day as computer or computer peripheral, yet, reaching compact purpose for making electronic product, the spendable configuration space of this electronic product internal electrical components also correspondingly will reduce.With the host computer is example, current most popular notebook type or pocket computer inside have been crowded with various electronic building bricks, wherein the shared space of connector is very big, and most connector is again the standard configuration of industry, must install and can not omit, promptly be used to connect various ancillary equipment such as keyboard etc. as micro connector (MINI din connector) commonly used.Therefore the volume of connector is effectively reduced,, become the very important problem of current computer producer to improve the utilization rate of computer inner space or circuit board arrangement.

More current micro connectors commonly used are used for laptop and still dislike big; its problem is; the terminal of micro connector commonly used is divided into number row and is soldered on the circuit board; therefore can take more space; related insulation wall and the necessary corresponding lengthening of metallic shield housing wall face that makes the micro connector insulating body is to shield and to protect the terminal in it.Line up same row though have the design of some micro connectors commonly used to make to be welded on the number row terminal legs on the circuit board, yet its terminal structure is not too complicated, row's terminal bending structure differs or is not symmetrical together exactly, so not only increase the difficulty of its assembling, and because of terminal structure too complexity length is increased, cause the overall volume of this micro connector really to dwindle.Secondly, another reason that micro connector volume commonly used is difficult for reduction is, the volume of micro connector is littler, can also correspondingly reduce for the volume at the position of secure bond in the design between its insulating body and the shield shell, the stationarity variation, so that micro connector is after repeatedly plugging with butt connector, and this shield shell gets loose on the body that insulate easily.

Existing micro connector is found in the Taiwan patent application the 77208107th, 78204790,80104898,80208342,80211820,82111200,82201874 and No. 84201441, and United States Patent (USP) the 4th, 637,669,4,842,554,4,842,555,4,908,335,4,995,819,5,017,158 and 5,186, No. 633.

For solving prior art problems, main purpose of the present utility model provides a kind of micro connector, the extension of wherein most row's terminals can both extend in the mode of the back insulation wall of pressing close to insulating body, and comply with different rows and count the angle excursions that the terminal extension has different sizes, make angle excursion keep symmetry with row's terminal extension, can make terminal more or less freely in assembling like this, simultaneously also can make the terminal foot section that is disposed on the circuit board all is same linear array, reduces shared board area significantly.
