Description
[technical field]
The utility model relates to a kind of test connector, refers to a kind of circuit daughter board test electric connector especially.
[background technology]
Now, various electronic products such as computer equipment etc. have become indispensable some in people's work and the life, increase along with its demand, also or else disconnected the increasing of demand of its corresponding intraware and extension facility (as various circuit daughter boards etc.), for guaranteeing the quality of intraware and extension facility (various electronic cards etc.), manufacturer needs its performance is tested before dispatching from the factory.
There is a kind of being used for that the circuit daughter board is carried out the test trough connector now, as shown in Figure 6.Described test connector electrically connects circuit daughter board (not icon) to testing circuit board (not icon), comprise a upper body a and body b once, an insertion groove a1 who provides described circuit daughter board to peg graft is provided described body, described insertion groove a1 two opposite side walls inner surface is concaved with a plurality of terminal groove a2, the described terminal groove a2 of described insertion groove a1 lateral communication; A plurality of conducting terminal c are arranged in the described terminal groove a2, and each described conducting terminal c is equipped with a fixed part c1, grip by described upper body a and described body b down, described fixed part c1 upper end extension is provided with one first contact site c2, the described first contact site c2 is revealed in the described insertion groove a1, when described circuit daughter board was plugged in described insertion groove a1, described first contact site c2 and described circuit daughter board electrically connected; Described fixed part c1 lower end is extended and to be provided with one second contact site c3, and the described second contact site c3 is revealed in bottom the body b that descends of institute, in order to connect mutually with described testing circuit board.
Yet there is following shortcoming in this kind test connector:
1. described first contact site and described second contact site are extended to form respectively by the two ends of described fixed part, and telecommunication signal is very long by the transmission path between described first contact site and described second contact site, and then influence the high frequency characteristics of described test connector;
2. after described first contact site extends bending for several times by described fixed part, be revealed in the described insertion groove, through after the repeatedly plug of described circuit daughter board, described first contact site is easy to distortion, and then generation elastic fatigue, so the stability and the anti-plug of described test connector have much room for improvement, with useful life extended period.
Therefore, the test that industry is released a kind of circuit daughter board as shown in Figure 7 again is electrically connected, in terminal groove a2, be provided with an elastomer d of insulation, described terminal is provided with a fixed part c1 and is held on described upper body a and described down between the body b, described fixed part c1 is bent to form one second contact site c3 towards described elastomer d extension on every side, the described second contact site c3 be revealed in the body b that descends bottom, in order to connect mutually with described testing circuit board; Extend and be provided with one first contact site c2, the described first contact site c2 is revealed in the described insertion groove a1, when described circuit daughter board is plugged in described insertion groove a1, described first contact site c2 and described circuit daughter board electrically connect, addressing the aforementioned drawbacks, yet, bring following point again:
1. the monolateral described upper body and described down between the body that is clamped and fastened on of described fixed part, when described circuit daughter board is plugged in described insertion groove, described first contact site is subjected to that described circuit daughter board inserts extruding and when stepping down to described terminal groove, described second contact site also can the generating unit displacement component, thereby scrape and decrease described testing circuit board, cause the described testing circuit board life-span to reduce.
2. described elastomer is generally the plastic material of insulation or for the silica gel material, and is easily aging and lose original elasticity for a long time under the high temperature test environment, thereby causes described terminal chucking power deficiency, can't guarantee to provide excellent electrical property to connect.
3. the described fixed part of described test connector all by described upper body and body clamping down, need be offered two molds respectively to produce, and has increased the additional mold cost; In addition, described terminal needs earlier described terminal to be placed in described upper body bottom when mounted, described lower body is installed is again fixed clamping, has increased extra assembly cost, so its cost is very expensive.
Therefore, need a kind of new test connector of design, to overcome above defective.
[utility model content]
