The Phalanx syringe cylinder structure, for example 4*16 probe syringe is combined in a cube with constant spacing, apart from two kinds of syringe arrangement modes are arranged, a kind of be the needle mould formula of arranging usually at each, corresponding single double arrange interface more; A kind of is interleaving mode, corresponding DB9 15 25.Can insert probe according to actual conditions, draw the signal measurement of 2*10 port as need, can insert 2*10 probe, the cube top and bottom are fluted, can embed between specific clamping plate, the rectangle frame, and the Phalanx syringe is provided with the external interface of X*Y; Rectangle frame is provided with and screws nut, can cube is closely fixing, and plug and rectangle frame are an integral body, can insert probe holder and fix.The 4*16 signal wire boundling that connects can be fixed on the probe mechanical arm by band.

Rectangle frame length is slightly larger than cubical length, and the rectangle frame both sides have guide rail restriction clamping plate to slide at guide rail.

Bottom surface auxiliary needle battle array: constitute by main mechanical arm, probe mechanical arm, pedestal, probe holder, main mechanical arm and probe mechanical arm can be realized positioning of rotating in the plane, probe holder can be inserted the signal of different probe structure realization PCBA and draw, whole riveted joint and pedestal, mechanism not the time spent recoverable in pedestal.

Main mechanical arm: can rotate at surface level, can pass through screw means, be fixed in the demand position.

The probe mechanical arm: can rotate at surface level, an end and the riveted joint of main mechanical arm, the other end connects probe holder for the cover head mechanism.

Pedestal: main mechanical arm is riveted on pedestal, and there is the corresponding signal output interface pedestal front portion.

Probe holder: can insert various probe, pressure bar, Phalanx syringe.

The beneficial effects of the utility model are:

The simple and easy anchor clamps of multi-usage described in the utility model take up an area of little, and the time spent is not recoverable; Corresponding different PCBA draws by the traveling probe position different signal of realization; Anchor clamps lead-in wires overlaps the recycling that can realize anchor clamps with relevant test instrumentation or feature board.

Embodiment

Described anchor clamps have additional Phalanx syringe and bottom surface auxiliary needle battle array.

Fig. 1 is the Phalanx syringe cylinder structure, is made up of three parts, and for example 4*16 probe syringe is combined in a cube 101 with constant spacing, and apart from two kinds of syringe arrangement modes are arranged, a kind of be the needle mould formula of arranging usually at each, corresponding single double arrange interface more; A kind of is interleaving mode, corresponding DB9 15 25.Can insert probe according to actual conditions, draw the signal measurement of 2*10 port as need, can only insert 2*10 probe, cube top and bottom fluted 104, can embed between clamping plate 201, the rectangle frame 202,4*16 signal wire boundling 102 can be fixed on the probe mechanical arm 303 by band, and the Phalanx syringe is connected with the external interface 103 of 4*16.

Rectangle frame 202 length are slightly larger than the length of cube 101, and rectangle frame 202 both sides have guide rail restriction clamping plate 201 to slide at guide rail.

Rectangle frame 202 is provided with and screws nut 203, can cube 101 is closely fixing, and plug 204 is an integral body with rectangle frame 202, can insert probe holder and fix.
