Description
Technical field
The utility model belongs to PCB circuit board manufacture field, more particularly, to a kind of pcb board welding resistance exposure aligning pin.
Background technology
Printed circuit board (PCB) (pcb board) is made of the pad of insulating base, connecting wire and erection welding electronic component, tool
There is the double action of conducting wire and insulating base, be a kind of extremely important assembling parts in electronic equipment.
The pin bottom area used at present is all bigger, because the thickness of the bottom of pin in 0.2 millimeter, is hindering
It is more that defect is underdeveloped during weldering exposure.Such pin there are the problem of：For the narrow product of blanket edges of boards, because pin from figure compared with
Closely, it is easy to cause and underdevelops；During each converted products, pin and film need to be reinstalled, waste of time.
The content of the invention
The purpose of the utility model is to overcome the shortcomings that the prior art, providing a kind of pcb board welding resistance exposure aligning pin,
It can prevent from causing to underdevelop because of pin.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of pcb board welding resistance exposure aligning pin
Nail, including nut, pin and egative film, is provided with pin fixing groove, the pin is arranged on the pin and fixes in the nut
In slot, external screw thread is provided on the pin, mounting hole is provided on the egative film, internal thread, institute are equipped in the mounting hole
It states egative film to be arranged on the pin, and passes through the internal thread and external screw thread mating connection, the length of pin compares institute
State pin fix groove depth it is 1-5 millimeters long, the pin lower end is provided with 45 ° of cone angle circular conical surfaces.
Further, the pin is interference fitted with the pin fixing groove.
Further, the egative film is a diameter of 6 millimeters of circular configuration.
Further, the nut outer surface is provided with anti-skidding embossing.
Further, the nut is quadrilateral structure.
The utility model has the advantages and positive effects of：Due to the adoption of the above technical scheme, prevent from causing because of pin
It underdeveloping, pin is mounted directly on film, without removing, easy to operate, saving man-hour；And with simple in structure, behaviour
Make the advantages that convenient, efficient.
Description of the drawings
Fig. 1 is utility model works structure diagram
Fig. 2 is the utility model structural decomposition diagram
In figure：
1st, nut 101, pin fixing groove 102 it is anti-skidding embossing,
2nd, 202,45 ° of pin 201, external screw thread cone angle circular conical surfaces
3rd, egative film 301, mounting hole 301, internal thread

Specific embodiment
The utility model is described further with reference to embodiment and attached drawing.
As shown in Figure 1 to Figure 2, the present embodiment provides a kind of pcb board welding resistance exposure aligning pin, including nut 1, pin 2
With egative film 3, pin fixing groove 101 is provided in nut 1, and pin 2 is arranged in pin fixing groove 101, and pin, 2 fix with pin
Slot 101 is interference fitted, and external screw thread 201 is provided on pin 2, and mounting hole 301 is provided on egative film 3, is equipped in mounting hole 301 interior
Screw thread 302, egative film 3 are arranged on pin 2, and pass through internal thread 302 and external screw thread 201 is connected, and 2 length of pin compares pin
101 depth of fixing groove is 1-5 millimeters long, and 2 lower end of pin is provided with 45 ° of cone angle circular conical surfaces 202.
Egative film 3 is a diameter of 6 millimeters of circular configuration.
Easy to use in order to increase frictional force, 1 outer surface of nut is provided with anti-skidding embossing 102, and nut 1 is quadrangle knot
Structure.
The course of work of this example：In use, being first connected pin 2 with 1 interference of nut, pin 2 passes through glue after connection
Egative film 3 from 2 bottom of pin is inserted in, and is connected with the external screw thread 201 on pin 2 by the hole on piece 4, at this point, being clipped in egative film 3
Film 4 between nut 1 is fixed.Pin 2 is inserted into the hole of pcb board 5 afterwards, film 4 is made to navigate on pcb board 5, most
Manual target contraposition is carried out afterwards.Overall structure from pcb board 5 need to only be taken out after work, directly carry out next
The contraposition operation of pcb board 5, pin 2 are fixed on film 4, save man-hour.
The beneficial effects of the utility model are：Due to the adoption of the above technical scheme, prevent from causing to underdevelop because of pin, sell
Nail is mounted directly on film, without removing, easy to operate, saving man-hour；And with simple in structure, easy to operate, efficiency
The advantages that high.
One or more embodiments of the utility model are described in detail above, but the content is only this practicality
New preferred embodiment, it is impossible to be construed as limiting the scope of the utility model.It is all according to present utility model application model
Made all the changes and improvements etc. are enclosed, should all still be belonged within the patent covering scope of the utility model.
