[technical field]

The utility model relates to a kind of electric connector, refers in particular to a kind ofly to be made of public connector and female connectors, electrically connects the Board-to-Board Electrical Connector of two circuit boards simultaneously.

[background technology]

Along with the development of electronic product towards weak point, little, light, thin direction, each type electric connector also develops to miniaturization accordingly, especially the Board-to-Board Electrical Connector that has less external configuration is used widely owing to it can dwindle taking up room of circuit board greatly.

United States Patent (USP) announces the 5th, 975, disclosed a kind of Board-to-Board Electrical Connector for No. 916 with less external configuration, this electric connector is made up of the plug and socket of butt joint, plug comprises some conducting terminals that are parallel to each other and the insulating body of accommodating this conducting terminal, and each conducting terminal is contained in respectively in the terminal containing slot on the insulating body; Wherein terminal containing slot is " コ " shape slot configurations, each conducting terminal comprises a contact arm and a fixing arm, the relative both sides of fixing arm outwards are convexly equipped with a strip projection and a cornu respectively, wherein the strip projection is inserted in the fluting on sidewall of aforementioned terminal containing slot, and cornu is resisted against on another opposing sidewalls.Because aforementioned terminal containing slot is " コ " shape slot configurations, conducting terminal only depends on holding mutually of strip projection on the fixing arm and the fluting on the terminal containing slot sidewall, and conducting terminal is retained in the insulating body.

Because low profile Board-to-Board Electrical Connector external configuration is less, and, make that the spacing between terminal is very little along with the development of high density conducting terminal, thus aforementioned terminal containing slot sidewall do very thin, it is excessive that the strip projection on the conducting terminal can not be done.In the process that plug and socket plugs mutually, the contact arm of plug terminal can be subjected to the effect of longitudinal frictional force, thereby be passed on the strip projection on the fixing arm, make and have the effect of power between strip projection and the fluting, because this two structure is comparatively weak, thereby under the effect of power, easily cause the two damage, and influence fixing effect, further influence electrical contact the between plug terminal and female terminal.

[summary of the invention]

The purpose of this utility model is to provide a kind of Board-to-Board Electrical Connector with less external configuration, has improved the fixing effect of conducting terminal in insulating body, has guaranteed the reliable contact between the male and female terminal.

For achieving the above object, the utility model adopts following technical scheme: a kind of Board-to-Board Electrical Connector, the public connector and the female connectors that comprise butt joint, public connector comprises first insulating body and is housed in some first conducting terminals in first insulating body, first conducting terminal is the audio prong like substantially, comprise first welding foot, first contact arm and the first fixing arm, female connectors comprises second insulating body and is housed in some second conducting terminals in second insulating body, second conducting terminal becomes the serpentine structure substantially, comprises second leg, second contact arm and the second fixing arm.

Compared to prior art, the utility model first conducting terminal is the audio prong like substantially, the one-body molded setting of insulating body of the first fixing arm and public connector on it, improve the fixing effect of male terminal in insulating body, guaranteed reliable contact the between first conducting terminal and second conducting terminal.

[embodiment]

Please refer to Fig. 1 to shown in Figure 4, a kind of Board-to-Board Electrical Connector that is used to connect two printed circuit board (not shown), constitute by public connector 30 and female connectors 10, wherein the structure of each connector is flat, so that have less height during the butt joint of male and female connector, and help firm being welded on the printed circuit board (PCB) of each connector.

Please refer to Fig. 1, Fig. 3 and shown in Figure 5, aforementioned public connector 30 comprises first insulating body 31 of being made by insulating material, and group is provided with first conducting terminal 40 that two rows are parallel to each other on this first insulating body 31.First conducting terminal 40 is to be stamped to form by sheet metal, cardinal principle audio prong like, comprise that one connects base portion 45, by connecting base portion 45 horizontal-extendings one first welding foot 41, in order to public connector 31 is welded in (not shown) on first printed circuit board (PCB), upwards vertically be extended with the first parallel each other contact arm 42 and the first fixing arm 43 by connecting base portion 45, wherein one guidance part 46 is set at first contact arm, 42 front ends, this guidance part 46 is an inclined surface, second contact site 25 with guiding female connectors 10 slides with respect to this inclined surface, contiguous this guidance part 46 outwards vertically is convexly equipped with one first contact site 47, outwards vertically convexes with cornu 44 respectively in the first fixing arm, 43 both sides.

Aforementioned first insulating body 31 comprises that one is the embedding boss 32 of flat rectangular shape, accommodate two in the vertical both sides that embed boss 32 and ranked first conducting terminal 40, the first fixing arm 43 of this first conducting terminal 40 is to be made of one piece with embedding boss 32, and be housed in the holding slot 34 (as shown in Figure 5) that embeds on the boss 32, first contact arm 42 of first conducting terminal 40 is housed in the accepting groove 33 that embeds boss 32 vertical both sides.Because fixing arm 43 is made of one piece with embedding boss 32, and the first fixing arm, 43 both sides are provided with cornu 44, therefore can make 40 firm being retained in the holding slot 34 of first conducting terminal.

Please refer to Fig. 2, Fig. 4 and shown in Figure 5, aforementioned female connectors 10 comprises second insulating body 11 of being made by insulating material, and group is provided with second conducting terminal 20 that two rows are parallel to each other on this second insulating body 11.Second conducting terminal 20 is to be stamped to form by sheet metal, becomes the serpentine structure substantially, this serpentine structure by one just " U " shape structure 23 and fall " U " shape structure 22 and form, and this two structure is by common linking arm 27 connections; Another of " U " shape structure 22 branches into the second fixing arm 28, and its both sides outwards vertically convex with hangnail 26 respectively, in order to second conducting terminal 20 is retained on second insulating body 11; Perpendicular to the second fixing arm, 28 horizontal-extendings second welding foot 21 is set, in order to female connectors 11 is welded on second printed circuit board (PCB) (not shown); Another of aforementioned just " U " shape structure 23 branches into an elastic contact arm 24, and these elastic contact arm 24 ends outwards vertically are convexly equipped with one second contact site 25, in order to be connected with 45 electric connections of first contact site or the signal of aforementioned first conducting terminal 40.
