Description
[technical field]
The utility model relates to the docking facilities of the movable identification key of a kind of tool.
[background technology]
Because the variation of computer function, for satisfying the user its computer equipment is done expansion on the function, therefore computer maker is reserved several docking facilitiess again after basic outfit is provided on computer main frame panel, be convenient to the user according to its circuit daughter board that need peg graft different, expand its computer function.
Because the difference of circuit daughter board is the various circuit daughter board of pegging graft, so computer maker must install multiple docking facilities on motherboard, could satisfy user's needs.Yet the space on the motherboard is limited after all, therefore obviously can't arbitrarily increase the quantity of edge connector; Moreover user regular meeting is subject to the specification of docking facilities on the motherboard, can't choose at random the circuit daughter board that its desire is pegged graft, and this will expand to computer function and bring difficulty; In addition, in order to adapt to different circuit daughter boards, so must have docking facilities and its coupling of different size on the motherboard, and this increases also and makes and development cost.
In addition, for the circuit daughter board to various different sizes carries out performance test, computer maker must be installed multiple docking facilities on test board, could satisfy the needs of test.
Yet, space on the test board is limited after all, therefore obviously can't arbitrarily increase the quantity of docking facilities, and the multiple docking facilities gesture of installing need be selected to discern corresponding kind of docking facilities and carries out corresponding circuit daughter board and carry out performance test on the test board, this certainly will influence the speed and the efficient of test; Moreover user regular meeting is subject to the specification of docking facilities on the test board, can't arbitrarily test the circuit daughter board of its required detection, and this will bring difficulty to the detection of circuit daughter board; In addition, in order to adapt to the testing requirement of different circuit daughter boards, so must have docking facilities and its coupling of different size on the test board, and this increases also and makes and development cost.
In order to improve these defectives, a kind of docking facilities of circuit daughter board of the different size that can be used for pegging graft has appearred in industry, for example the patent No. is 97103093.6 Chinese patent, it has disclosed a pair of tipping and has put 2, it has a movable identification key 15, can be inserted in the relevant position of the terminal slots 11 of docking facilities 2 from top to bottom, to reach can the peg graft purpose of different circuit daughter boards of a docking facilities.
Yet there is following shortcoming in this kind docking facilities: 1. the identification key from top to bottom is inserted in the terminal slots when movable, and is not easy to plug, generally needs bigger power or it could be extracted by relevant aid; 2. be difficult for accurately location when the identification key is inserted in terminal slots from top to bottom when movable, unpunctual when locating, inclined to one side phenomenon appears inserting probably, and then collide conducting terminal in the terminal containing slot that is arranged at the terminal slots lateral communication, thereby the damage conducting terminal, and then influence the good serviceability of whole docking facilities.
Therefore, be necessary to design a kind of new docking facilities, to overcome above-mentioned defective.
[summary of the invention]
The purpose of this utility model is to provide a kind of docking facilities, it has movable identification key, can cooperate the choice of location ground of the positioning recess of different circuit daughter boards to insert docking facilities, this movable identification key has the dismounting of being easy to, replace easy advantage, and this movable identification key accurate positioning can not collide or damage conducting terminal partially because of inserting.
The utility model docking facilities, a circuit daughter board is used to peg graft, described circuit daughter board bottom is provided with at least one positioning recess, comprise: an insulating body, described insulating body offers a terminal slots for described circuit daughter board grafting, described insulating body offers at least one positioning through hole in described terminal slots side, described positioning through hole laterally runs through the two sides of described insulating body, and when described circuit daughter board was plugged in described terminal slots, at least one described positioning through hole was just overlapping for described positioning recess correspondence; At least one movable identification key selectively is inserted in the described positioning through hole of one of described insulating body.
The utility model docking facilities, described insulating body offers at least one positioning through hole in described terminal slots side, described positioning through hole laterally runs through the two sides of described insulating body, and when described circuit daughter board is plugged in described terminal slots, at least one described positioning through hole is just overlapping for described positioning recess correspondence, at least one movable identification key, selectively be inserted in the described positioning through hole of one of described insulating body, be that described movable identification key selectively inserts or extracts in described positioning through hole from the side direction of described insulating body, so if when need to change inserting the position of key, the object at only with hand or the sharp-pointed position of any tool is on every side replaced an ora terminalis of described movable identification key slightly, make its another relative ora terminalis protrude from the lateral margin of insulating body slightly, grasp the end that described movable identification key protrudes from the lateral margin of insulating body 1 then, can easily its level be extracted, then, select other slotting key position to insert again.So described movable identification key is easy to dismounting, replacing is easy, and has avoided setting up specific auxiliary body by specific aid or on described movable identification key, and increases the difficulty of dismounting or the difficulty and the cost of manufacturing; And described movable identification key alternative is inserted or is extracted in described positioning through hole from the side direction of described insulating body, so described movable identification key accurate positioning, can not collide or damage conducting terminal partially, and then influence the good serviceability of whole docking facilities because of inserting.
