The utility model content:
The purpose of the utility model is exactly to the deficiency of prior art existence a kind of power and high proving installation of precision of connecting into to be provided.
To achieve these goals, the technical scheme of the utility model employing is:
Proving installation; It includes holder, the floating seat be connected the holder bottom of floating, be fixed on circuit board on the floating seat, be fixed on testing needle on the floating seat, be slidingly arranged in the reference column on the floating seat; The upper end of testing needle is connected with circuit board; The floating seat bottom is stretched out in its lower end, and the floating seat bottom is stretched out in the bottom of reference column, is provided with spring between reference column and the floating seat.
Be provided with a plurality of balls between said holder and the floating seat, the holder bottom offers a plurality of mounting grooves corresponding with ball, and the top of ball is arranged in the mounting groove.
The bottom of said floating seat is provided with a plurality of stop collars that vertically run through floating seat, and sliding in the stop collar is provided with limited screw, and the thread end of limited screw passes stop collar and is threaded in the holder bottom.
Said floating seat is provided with the copper sheathing corresponding with reference column, and reference column is slidingly arranged in the copper sheathing.
Said reference column and copper sheathing are respectively two.
The top card of said reference column is connected to jump ring.
The utility model beneficial effect is: the utility model includes holder, the floating seat be connected the holder bottom of floating, be fixed on circuit board on the floating seat, be fixed on testing needle on the floating seat, be slidingly arranged in the reference column on the floating seat, and the upper end of testing needle is connected with circuit board, and stretch out bottom the floating seat its lower end; The floating seat bottom is stretched out in the bottom of reference column, is provided with spring between reference column and the floating seat, two objects that needs connect; The part of one of them object is fixed on the equipment, and another part is fixed on the floating seat, and another has pilot hole and the test point that is used to be electrically connected above object; When two objects connected, the reference column on the floating seat contacted with the pilot hole of another object, receives the thrust of side direction; Floating seat can float in the vertical plane of closure, thereby the electrical appliance part of the electrical appliance part of guiding on the floating seat and another object overlaps accurately, can be automatically the contact portion of two connection objects be coupled together with position accurately; Easy to use; Connect fast, improved the utilization factor and the production efficiency of testing apparatus, reduced the waste of manpower and materials; Practice thrift cost, increase the service life.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the decomposing schematic representation of the utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described; See shown in Fig. 1~2; Proving installation; It includes holder 1, the floating seat 2 be connected holder 1 bottom of floating, be fixed on circuit board 3 on the floating seat 2, be fixed on testing needle 4 on the floating seat 2, be slidingly arranged in the reference column 5 on the floating seat 2, and the upper end of testing needle 4 is connected with circuit board 3, and floating seat 2 bottoms are stretched out in its lower end; Floating seat 2 bottoms are stretched out in the bottom of reference column 5, are provided with spring 6 between reference column 5 and the floating seat 2.
Be provided with a plurality of balls 7 between holder 1 and the floating seat 2, holder 1 bottom offers the corresponding mounting groove 11 of a plurality of and ball 7, and the top of ball 7 is arranged in the mounting groove 11, and ball 7 makes the steady and smooth of sliding between floating seat 2 and the holder 1.
The bottom of floating seat 2 is provided with a plurality of stop collars 8 that vertically run through floating seat 2, and sliding in the stop collar 8 is provided with limited screw 9, and the thread end of limited screw 9 passes stop collar 8 and is threaded in holder 1 bottom.
Floating seat 2 is provided with the copper sheathing 10 corresponding with reference column 5, and reference column 5 is slidingly arranged in the copper sheathing 10.Reference column 5 is respectively two with copper sheathing 10, and the top card of reference column 5 is connected to jump ring 12, prevents that reference column 5 breaks away from from copper sheathing 10.
Two objects that needs connect, the part of one of them object is fixed on the equipment, and another part is fixed on the floating seat 2; Another has pilot hole and the test point that is used to be electrically connected above object, when two objects connected, the reference column 5 on the floating seat 2 contacted with the pilot hole of another object; Receive thrust and the support of ball 7 and the restriction of stop collar 8 of side direction; Floating seat 2 can float in the vertical plane of closure, thereby the electrical appliance part of the electrical appliance part of guiding on the floating seat 2 and another object overlaps accurately, can be automatically the contact portion of two connection objects be coupled together with position accurately; Easy to use, connect fast.
Use with being connected in test, improved the success ratio of connection greatly, reduced waste.In the test of conventional mobile phone mainboard test; The module average test success ratio of traditional structure is at 1600PPM; The module of utilizing the utility model is not to bad product occurring, and the life-span of test module obtains very big prolongation, has improved the utilization factor and the production efficiency of testing apparatus; Reduce the waste of manpower and materials, practiced thrift substantial contribution.
Certainly, the above only is the preferred embodiment of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
