Description
[technical field]
The utility model relates to a kind of electric connector, is meant a kind of electric connector with the short-circuit function of preventing especially.
[background technology]
Development along with electronic industry, electric connector is more and more important in the effect of electron trade performance, therefore the demand of electric connector high-quality performance also highlights day by day, under equal conditions, wants to make efficiency of transmission to be improved, the way that industry is general is the quantity that increases terminal, yet under the more and more littler situation of mainboard, the space of the shared mainboard of electric connector that is bound to also diminishes thereupon, thereby make described terminal need densification to arrange, so just go out the design of a series of associated electrical connectors at the sound.
Early stage a kind of electric connector, it comprises an insulating body, offer into most accepting holes of horizontal and vertical arrangement on the described insulating body, most terminals correspondence respectively are installed in most described accepting holes, and each described terminal has a base portion, and described base portion is located in the described accepting hole, one elastic arm extends upward from described base portion and forms, and partly extending described accepting hole, a contact site is located at the end of described elastic arm, and a weld part forms from the extension downwards of described base portion.The described accepting hole of back row that vertical front-seat described accepting hole of arranging is adjacent is positioned on the same longitudinal direction, and the described elastic arm of the described terminal of back row also is positioned on the same longitudinal direction with the described elastic arm of the adjacent described terminal in front row.
Described electric connector is used for a chip and is packed into, when described chip is installed on the described insulating body, described chip carries out the crimping contact to the described contact site of described terminal, at this moment, be positioned at same vertical row and two adjacent described terminals, the described elastic arm of the described terminal of back row is positioned at the described elastic arm top of front-seat described terminal, and described chip correspondence connects mutually with described contact site.But there are some problems in so described electric connector, because the comparatively dense that described terminal is arranged in the described electric connector, when described chip presses down excessive or malfunction, front-seat described elastic arm is touched mutually with easy between the adjacent described elastic arm of back row, thereby can cause the interference of short circuit or signal.
Problem at above-mentioned described electric connector appearance, industry derives another electric connector again, described electric connector comprises an insulating body, offer into most accepting holes of horizontal and vertical arrangement on the described insulating body, most terminals correspondence respectively are installed in most described accepting holes, each described terminal has a base portion, described base portion is located in the described accepting hole, one elastic arm extends upward from described base portion bending inclination and forms, and part is extended described accepting hole, one contact site is located at the end of described elastic arm, and a weld part forms from the extension downwards of described base portion.The described accepting hole of back row that vertical front-seat described accepting hole of arranging is adjacent is positioned on the same longitudinal direction.
Described electric connector is used for a chip and is packed into, when described chip is installed on the described insulating body, described chip carries out the crimping contact to the described contact site of described terminal, at this moment, be positioned at same vertical row and two adjacent described terminals, the described elastic arm of the described terminal of back row is between the described elastic arm of the adjacent two described terminals in front row, and described chip correspondence connects mutually with described contact site.Though solve the problems such as short circuit that occur easily in the early stage described electric connector like this, but brought new problem, roughly as follows:
1. the described elastic arm of described terminal is from the oblique extension of described base portion, because described elastic arm all has bigger elasticity, so easy beat of described elastic arm, and described contact site is in the end of described elastic arm, when described chip presses down described contact site, the phenomenon of loose contact appears easily like this.
2. the described elastic arm of described terminal upward deflects angle by described base portion and extend to be provided with, as careless manipulation a little then still can make adjacent as described in terminal cause the phenomenon of short circuit.
3. under the little situation of described terminal constancy of volume, the volume of described accepting hole does not diminish yet, and arrangement mode still is the arrangement of array transverse and longitudinal, improve the efficiency of transmission of described electric connector if desired, so then need to increase the quantity of described terminal, and then the volume of described insulating body must increase, and it is then more that described electric connector takies the space of mainboard simultaneously.
4. when described chip is installed on the described insulating body, owing to can be provided with assemblies such as buckling device and radiator on the described chip, can apply bigger pressure to described chip, and described chip is directly to be crimped on the described contact site of described terminal, and there is not other supporting construction can bear above-mentioned pressure, so described terminal is easy to damage or tired, thereby influences electrically conducting of described electric connector.
Therefore, be necessary to design a kind of new electric connector, to overcome the problems referred to above.
[utility model content]
Creation purpose of the present utility model be to provide a kind of both had to utilize shift to install to prevent short circuit, can reach the electric connector of the purpose that takes up space less again.
In order to achieve the above object, adopt following technical scheme at electric connector of the present utility model:
A kind of electric connector, it comprises an insulating body, before and after being, described insulating body is provided with most accepting grooves to row, each described accepting groove is to run through on the described insulating body to be provided with one first accommodation section, horizontal side extension in described first accommodation section is provided with one second accommodation section, rear side extension in described first accommodation section is provided with one the 3rd accommodation section, described second accommodation section of the described accepting groove of back row is positioned at the rear side of described the 3rd accommodation section of the front-seat described accepting groove that is adjacent, in addition, the convex at least two protection pieces that are provided with of described insulating body, and multi-conducting terminals, correspondence is located in most described accepting grooves respectively, each described conducting terminal has a base portion, and described base portion is across being positioned at described first accommodation section and described second accommodation section; One strip connecting portion, described strip connecting portion extend on a side direction of described base portion and enter described second accommodation section, the more described strip connecting portion of described protection piece height; One elastic arm, described elastic arm from a side of described base portion earlier backwards more forward and integral body extend upward, described elastic arm is adjacent with described strip connecting portion and cross described strip connecting portion, and enter described the 3rd accommodation section by described first accommodation section and extend upward described accepting groove again, simultaneously, the described elastic arm of back row's described conducting terminal is between the adjacent two described elastic arms at front row.
