The utility model discloses a base convenient to contact pin components and parts welding or change paster, including base body, the inside supplementary intercommunicating pore that is provided with of base body, base body bottom is provided with reference column, base body's side and bottom surface and has seted up "L" type recess.

Preferably, the auxiliary communication holes are arranged in two groups, three groups, four groups or six groups, and the like, and the auxiliary communication holes are in a circumferential array.

Preferably, the auxiliary communication hole is an outer inclined hole or a vertical hole which is trumpet-shaped and is communicated with the top surface and the bottom surface.

Preferably, the positioning column is arranged as a column protruding downwards from the bottom surface.

Preferably, the "L" -shaped groove is connected to the auxiliary communication hole at the bottom surface.

Compared with the prior art, the beneficial effects of the utility model are that: it can insert the contact pin of components and parts to supplementary feed through in the hole, can conveniently carry out the separation of great degree with the contact pin of contact pin components and parts according to required crooked direction, can fix contact pin components and parts on the circuit board through its reference column, and it is all more convenient for follow-up manual welding or change paster technology welding into to improve production efficiency, reduce and occupy the circuit board area, reduce the waste to the circuit board.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in figures 1 to 6, a base convenient for welding pin components or changing patches comprises a base body 1, wherein an auxiliary communication hole 2 is formed in the base body 1, a positioning column 3 is arranged at the bottom of the base body, and an L-shaped groove 4 is formed in the side surface 7 and the bottom surface 6 of the base body. The base body 1 is made of plastic, nylon, ABS and other high-temperature resistant materials without conductivity.

Specifically, the base body 1 is in a cylindrical shape. The shape can provide the function of the gasket for the pin element and can also play a good supporting role.

Specifically, the auxiliary communication holes 2 may be two, three, four or six holes, and the like, and are distributed in a circumferential array, and when the implementation is specific, the number of the auxiliary communication holes 2 is set according to the number of pins of the pin device, and when the number of the pins of the pin device is 3, the auxiliary communication holes 2 are set to be 3, and the pins of the pin device are respectively inserted into the corresponding auxiliary communication holes 2.

Specifically, the auxiliary communicating hole 2 is formed as an outer inclined hole or a vertical hole, is trumpet-shaped, and communicates the top surface 5 and the bottom surface 6. Concrete implementation, after inserting contact pin components and parts into supplementary intercommunicating pore 2, can make contact pin components and parts's pin carry out the separation of great degree, outwards buckle more easily, supplementary intercommunicating pore 2 is big at the diameter of top surface 5, to 6 diameters that reduce gradually of bottom surface, is the loudspeaker form, can be more convenient insert supplementary intercommunicating pore 2 with contact pin components and parts's pin.
