Description
Technical field:
The utility model belongs to a kind of electronic equipment pick-up unit, particularly a kind of detection docking apparatus of laser sound pickup.
Background technology:
Laser sound pickup is also referred to as laser head, is parts commonly used in the present digitizing audio-visual equipment, uses very extensive.In the manufacturing process of laser sound pickup, test and the adjustment program that is absolutely necessary, that test and adjusting needs is stable, reliably product and checkout equipment are linked up.The finished product interface is the winding displacement of a 40pin, this winding displacement width is little, and is very fragile again, is easy to damage, but the connection that in test, all will aspire for stability to 40 signal line, thus cooperate with it pick-up unit interface requirement precision height, peg graft reliable, can repeated multiple times use loosening.
At present the connection of manufacturer's proving installation commonly used is the anchor clamps of contact pin type, or directly substitutes with the plug connector of product itself.In the practical application, the contact pin type anchor clamps are easy to generate contact pilotage pine, partially and the situation of loose contact and cause mistake to be surveyed, and are serious even can damage product and equipment, and cost is very high.When substituting with the connector of product own, it is high that the employee is operated requirement, inserts partially easily, can cause loose contact to cause damage equally, and the fixed sturcture of the connector of product itself all is disposable design, is not suitable for repeatedly using.
Summary of the invention:
The utility model is in order to overcome the described shortcoming of background technology, designs a kind ofly can repeated multiple times use, connect laser sound pickup pick-up unit reliable, easy to use, with low cost.
The utility model is made of base plate, gathering sill, product connector, anchor clamps, and gathering sill is located at the base plate front end, and gathering sill is both sides height, middle low groove, and bottom land is connected with base plate and maintains an equal level, and groove width is consistent with connector.Near the gathering sill place, be provided with the product connector on the base plate, with gathering sill at same straight line and parallel, establish anchor clamps on the base plate, the chuck width of anchor clamps and gathering sill close fit are pressed in connector the place ahead, the gathering sill.The base plate afterbody is provided with solder joint, and the contact of connector has circuit to be connected with these solder joints, and circuit connection is at the base plate upward wiring.
The preferred concrete structure of anchor clamps: clamping plate are arranged, and the clamping plate front end is a chuck, and the middle part crosswise fixed has a pin, base plate is provided with 1 pair of bracing frame, have pin-and-hole on the bracing frame, pin penetrates pin-and-hole, clamping plate are positioned in the middle of two bracing frames, and whole clamping plate are that the center is the seesaw structure with the pin.The tail end of clamping plate, and a spring is set between the base plate, spring is given elastic force of clamping plate tail end, makes clamping plate that the downward pressure of pair gathering sill be arranged.
Base plate preferably uses pcb board, and the circuit connection between the solder joint of base plate rear end and the product connector is directly at the pcb board upward wiring.
The utility model cost simple in structure is low, and is easily manufactured, but can the repeated multiple times utilization and do not influence the reliable and stable of connection, and it is also easy to operate, can maloperation.Can reduce the cost that manufacturing enterprise detects, debugs laser sound pickup greatly, increase work efficiency.
Description of drawings:
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is the front view (FV) that the utility model base plate does not have anchor clamps.
Embodiment:
In conjunction with Fig. 1 and Fig. 2 concrete structure of the present utility model is described.Base plate 1 adopts pcb board to make, front end is provided with design flexible circuit board (FCC) gathering sill 2, and these gathering sill 2 groove widths are consistent with the winding displacement width of product to be measured, guarantee that winding displacement just in time keeps flat into this gathering sill 2, bottom land is the plane, is connected and is same surface level with base plate 1.Product connector 3 is located on the base plate 1, nestles up the bottom land of gathering sill 1, and is parallel with bottom land, and in gathering sill 2 on same straight line.
Anchor clamps are made of clamping plate 4, bracing frame 5, pin 6 and spring 7, and clamping plate 4 heads are chuck 41, and chuck 41 width and gathering sill 2 close fit, clamping plate 4 middle part crosswise fixed have a pin 6, and clamping plate 4 are connected with bracing frame 5 by pin, and forming with the pin is the seesaw structure at center.Bracing frame 5 is fixed on the base plate 1, thereby reaches the stationkeeping of anchor clamps and base plate 1, concrete fixed position with chuck 41 can be parallel near connector 3, be pressed into gathering sill 2 and be as the criterion.For the pressure that guarantees anchor clamps reliable, the afterbody 42 of clamping plate 4, an and spring 7 is set between the base plate 2, spring 7 contact clamps 4 and base plate 1 utilize elastic force 42 perks of clamping plate afterbody, by the leverage of pin 6, chuck 41 are pressed in the gathering sill 2.Spring pressure is controlled at about 0.5N just can satisfy request for utilization.
Show that according to Fig. 2 connector 3 connects the circuitry lines 8 of coming out, and at base plate 1 upward wiring, is connected to the solder joint 9 of the rear end of base plate 1, and amplifies its spacing, so that connect other testing apparatuss.
During use, the contact 9 of apparatus of the present invention end is connected with relevant apparatus circuit for testing, connector 3 of the present utility model just has been connected with test and debugging equipment, depresses anchor clamps tail end 42, with chuck 41 perks, with the winding displacement of laser sound pickup to be measured or to be debugged from the utility model device front end, keep flat insertion connector 3 through gathering sill 2, unclamp anchor clamps tail 42, chuck 41 is depressed, winding displacement is pressed into gathering sill 2 fixing, just can guarantee that winding displacement has been electrically connected with the reliable of connector 3.
