Description
Technical field
The utility model is related to circuit board production techniques field, especially a kind of PCB thimbles.
Background technology
Nowadays ic manufacturing technology is very ripe, for many high density integrated circuit plates of component, usually use
Chip mounter carries out patch to circuit board.For double-sided PCB, two sides is all fixed with component, in order to facilitate patch and upper
Tin needs to jack up double-sided PCB, it will usually thimble is used, thimble can be inserted into the preset jack of double-sided PCB,
Whole circuit board jack-up to be raised.Existing this thimble, position are relatively fixed, it is difficult to are adjusted, due to two-sided electricity
The position of preset jack can not change on the plate of road so that a kind of thimble of structure arrangement is only applicable to a kind of circuit board, works as circuit
When the size of plate changes, then it is difficult to adjust.
Utility model content
The utility model provides a kind of PCB thimbles, facilitates the position of adjustment thimble, with the various sizes of circuit board of fixation.
A kind of PCB thimbles, including bottom bar, the bottom of the bottom bar is equipped with magnet；Connection is connected at the top of the bottom bar
Bar, the top side detachable formula of the connecting rod are socketed with sleeve；The top of the connecting rod is equipped with the putting hole axially extended,
Thimble is equipped in the putting hole, perforative through-hole is additionally provided on the sleeve, the thimble passes through the through-hole；The placement
Spring is additionally provided between the bottom in hole and thimble.
Preferably, the radius of the thimble is gradually reduced from bottom to top, and the aperture of the through-hole is less than thimble lower end
Radius.
Preferably, the madial wall of the sleeve is equipped with internal thread, and the top of the connecting rod is equipped with external screw thread, the sleeve
It is threadedly coupled each other with connecting rod.
Preferably, the bottom bar is in cone tubbiness.
Preferably, the bottom of the bottom bar is fixed with fixed disk, and the radius of the fixed disk is more than the radius of bottom bar, described
Magnet is embedded in the bottom of the fixed disk.
In the utility model, since the bottom of bottom bar is equipped with magnet, easily the absorption of entire PCB thimbles can be fixed to
Any position, to adapt to various sizes of circuit board.Sleeve and connecting rod detachable connection, can at any time remove sleeve,
To replace thimble, thimble is made to match with preset jack various sizes of on circuit board.Therefore, the PCB thimbles of the utility model
Applicability it is stronger, be more convenient for adjusting.
Description of the drawings
Fig. 1 is a kind of structure diagram of the PCB thimbles of embodiment of the utility model.
Specific embodiment
The utility model is described in further detail below by specific embodiment combination attached drawing.
The utility model embodiment provides a kind of PCB thimbles, as shown in Figure 1, part-structure component is observed for convenience, adopts
With the technique of painting of perspective.The PCB thimbles include vertically arranged bottom bar 1, and the bottom of the bottom bar 1 is equipped with magnet 5, and magnet 5 can
To be adsorbed onto on guide metal.The top of the bottom bar 1 is connected with connecting rod 2, and the extending direction of connecting rod 2 is parallel with bottom bar 1,
Sleeve 3 is socketed in the top side detachable formula of the connecting rod 2, the lower end of sleeve 3 forms opening, so as to envelope connecting rod 2
Top.The top of the connecting rod 2 is equipped with the putting hole 20 axially extended, and thimble 4 is equipped in the putting hole 20.It is described
Perforative through-hole is additionally provided on sleeve 3, thimble 4 upwardly extends, and across the through-hole and extends to except sleeve 3, and thimble 4 is inserted
Enter in the preset jack onto circuit board.Spring 21 is additionally provided between the bottom of the putting hole 20 and thimble 4, spring 21 carries
For elastic force, thimble 4 when pressed, has enough elastic reset power.
Entire PCB thimbles can be absorbed and fixed at the gold on chip mounter or tin cream machine by magnet 5 by the utility model
Belong to guide plate on, easily PCB thimbles can also be disassembled, to adjust the position of PCB thimbles, make its with it is preset on circuit board
The location matches of jack.Sleeve 3 and 2 detachable connection of connecting rod, can at any time remove sleeve 3, to replace radius difference
Thimble 4, thimble 4 is made to match with preset jack various sizes of on circuit board.
In one embodiment, the radius of the thimble 4 is gradually reduced from bottom to top, in cone shape.The set
The aperture of through-hole on cylinder 3 is less than the radius of 4 lower end of thimble, and the upper end of thimble 4 is then reached except sleeve 3, and this structure is set
It puts, sleeve 3 can be made to cover fixed thimble 4, thimble 4 is prevented to be detached from.
In one embodiment, the madial wall of the sleeve 3 is equipped with internal thread, and the top of the connecting rod 2 is equipped with outer spiral shell
Line, the sleeve 3 and connecting rod 2 are threadedly coupled each other, and the mode being connected through a screw thread can with realize sleeve 3 and connecting rod 2
It is detachably connected with.
In one embodiment, the bottom bar 1 is in cone tubbiness, when placing entire PCB thimbles so that bottom plate 1 is more steady
Gu.
In one embodiment, the bottom of the bottom bar 1 is fixed with fixed disk 11, and the radius of the fixed disk 11 is more than bottom
The radius of bar 1 so that 1 chassis of bottom bar is more firm, and the magnet 5 is embedded in the bottom of the fixed disk 11.
The above content is combine specific embodiment further detailed description of the utility model, it is impossible to assert
The specific implementation of the utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field
For, without departing from the concept of the premise utility, several simple deduction or replace can also be made.
