Abstract
The utility model discloses a wire holder comprising a connecting head and a wire cylinder connected in one body structure; the wire cylinder is a cylinder structure; the connecting head comprises a connecting ring and an inserting pipe; an outer diameter of the connecting ring is equal to the inner diameter of the wire cylinder; the connecting ring is on the bottom of the wire cylinder and connected in one body structure with the wire cylinder; the inserting pipe is a cylinder structure, an outer diameter of the inserting pipe is smaller than an inner diameter of a welding hole of a printed circuit board; the inserting pipe is connected in middle of the connecting ring and positioned below the wire cylinder; the wire holder of the utility model is firm, can prevent the wire from being damaged, and improves stability and reliability of the wire.
Description
Technical field
The utility model relates to a kind of fixing cord technology, particularly a kind of wire seat.
Background technology
In printed board, with signal between printed board is connected, the connection by wire is one of more common connected mode.Traditional wire does not add any protection and is directly welded in printed board, when line is many, when filament is thin, causes wire running before not connecting, and even occurs the situation of broken string.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of wire seat, and not running of guardwire, does not fracture, and improves the fastness of system wire.
In order to realize the object solving the problems of the technologies described above, a kind of wire seat that the utility model provides, by connector, line cylinder, formed, connector, line cylinder are structure as a whole, wherein, line cylinder be one columnar structured, connector comprises and connects annulus and insert cylinder, the external diameter that connects annulus is identical with the internal diameter of line cylinder, is positioned at line cylinder bottom, and into a single integrated structure with line tubular; Insert cylinder and be one columnar structured, external diameter is less than the internal diameter of the welding hole of printed board, is connected in the centre that connects annulus, and be positioned at line cylinder below.
Further concrete, the external diameter that inserts cylinder is less than the internal diameter 0.1 ~ 0.3mm of the welding hole of printed board.
The wire seat of this patent, its principle and using method are: wire and supporting line seat are matched, by wire wire stripping, wire stripping length 5-7 ㎜ is advisable, and the wire of warding off after tin is inserted in the line seat matching, and is inserted into the end, be welded, line seat and wire that plug-in mounting is good are welded in printed board, and line seat inserts thin the righting that will match with printed board pad of cylinder, is finally welded.
By adopting technique scheme, the utlity model has following beneficial effect:
The line seat of this patent is firm, can not damage by guardwire, has increased fastness, the reliability of wire.
Accompanying drawing explanation
Fig. 1 is the wire seat schematic diagram of this patent.
Fig. 2 is that the wire seat of this patent is used state diagram.。
In figure, 1-line cylinder, 2-inserts cylinder, 3-printed board, 4-pad, 5-connects annulus.
D1, d2, d3, d4 are respectively the internal diameter that inserts cylinder, external diameter, the internal diameter of line cylinder, the external diameter of line cylinder that inserts cylinder.
Embodiment
Below in conjunction with accompanying drawing, this patent is further explained.But the protection range of this patent is not limited to concrete execution mode.
As depicted in figs. 1 and 2, the wire seat of this patent, comprises that one is comprised of connector, line cylinder 1, line cylinder 1 be one columnar structured, the external diameter of the connection annulus 5 of connector is identical with the inner diameter d 3 of line cylinder, and forms integrative-structure with line cylinder 1; Insert the internal diameter that cylinder outside diameter d 2 is slightly less than the welding hole of printed board 3.The outside diameter d 2 of inserting cylinder is less than the welding hole 0.1 ~ 0.3mm of printed board 3.
The line seat of this patent as shown in Figure 1, by wire wire stripping, stranded after, from line seat butt end, insert line seat taper end, until stranded wire exposes from line seat taper end, be inserted into the end, be then welded in printed board 3, the righting that will match with printed board pad 4 of the taper end of line seat.
Claims (2)
1. a wire seat, it is characterized in that: by connector, line cylinder, formed, connector, line cylinder are structure as a whole, wherein, line cylinder be one columnar structured, connector comprises and connects annulus and insert cylinder, the external diameter that connects annulus is identical with the internal diameter of line cylinder, be positioned at line cylinder bottom, and into a single integrated structure with line tubular; Insert cylinder and be one columnar structured, external diameter is less than the internal diameter of the welding hole of printed board, is connected in the centre that connects annulus, and be positioned at line cylinder below.
2. wire seat according to claim 1, is characterized in that: the external diameter that inserts cylinder is less than the internal diameter 0.1 ~ 0.3mm of the welding hole of printed board.
