Abstract
The utility model discloses a surface mounting connector possessing an installation positioning function. The surface mounting connector includes a housing. The lower end of the housing is provided with surface mounting pins. The points are that the housing is provided with an installing hole and guiding positioning bolts; the guiding positioning bolts are pressed on the housing in an interference fit mode. The surface mounting pins on the lower end of the connector are in a horizontal surface mounting structure. The bolt adopts an interference press mounting structure, so the occupied space is small, and the connection is reliable and accurate. The front end of the guiding positioning bolt is in a cone structure, so the guiding positioning bolt is easy to pass through a positioning hole of a printed plate. A cylindrical part on the rear is in a transition fit with the positioning hole of the printed plate to prevent the movement of the connector, and consequently the precise positioning is reached. The technical problem of positioning difficulty in the welding of a conventional surface mounting connector is solved.
Description
Technical field the utility model belongs to technical field of electric connectors, is specifically related to a kind of surface pasting connector technology of tape guide installing and locating.
The general system installing hole of only on shell, opening of background technology conventional surface placing connectors; For eliminating the dimensional discrepancy of screw and user installation perforate; The size of installing hole is general all many greatly than the screw of installing; This must cause the position after connector is installed unfixing, and this causes very big trouble for the welding of surface pasting connector.Surface pasting connector generally adopts Reflow Soldering; The connector pinout that all requires before the welding to mount must align with the printed board pad; And conventional surface pasting connector does not have positioner, can only observe the position of pin and pad and adjusts with bore hole during practical operation, when adopting the screw installation; Screwing force very easily causes the connector deflection to not positive pad, and this causes very big difficulty for the welded and installed of connector.Particularly closely spaced surface pasting connector requires positioning accuracy high, and conventional surface pasting connector causes waste product easily when welding.
The purpose of summary of the invention the utility model provides a kind of surface pasting connector with installing and locating, has solved the technical problem that the prior art surface pasting connector is installed location difficulty when welding.
The surface pasting connector of the utility model band installing and locating; Comprise shell; The lower end of shell is provided with the Surface Mount pin; Its main points are that shell is provided with installing hole and guide-localization pin, and said guide-localization pin adopts the mode of interference fit to be fitted on the shell, and the Surface Mount pin of said connector lower end is that horizontal surface mounts structure; The structure that pin adopts interference to press-fit; Not only occupation space is little, and connection is reliable, precision is high, and said guide-localization pin front end is a tapered configuration; Be beneficial to the location hole that guiding penetrates printed board; The column part of back segment and the location hole of printed board form interference fits, prevent that the connector string is moving, thereby reach pinpoint purpose.
Guide positioning pin nail dimension precision on the utility model shell is high, and the horizontal Surface Mount pin of connector lower end as the shaping benchmark, has guaranteed the dimensional accuracy of connector pinout with shop bolt; Connector when mounted; Open system accurate localization hole according to the size of shop bolt in the printed board, after connector inserted the location hole of printed board with guide pin, it was moving not produce string; The relative position of pin and pad is unique, loaded down with trivial details adjustment when having avoided conventional surface pasting connector to install.In addition, owing to there is shop bolt to position, when installing hole that passes connector shell with screw and printed board were installed, the screwing force in the process can not make the position of connector produce and squint, and has guaranteed accurately aligning of connector pinout and printed board pad.
Description of drawings Fig. 1 is the utility model master TV structure sketch map;
Fig. 2 be among Fig. 1 A-A to cutaway view;
Fig. 3 is the utility model plan structure sketch map.
Among the figure: 1. shell 2. guide-localizations 3. Surface Mount pins of pinning
Embodiment is with reference to Fig. 1, Fig. 2 and Fig. 3; The surface pasting connector of the utility model band installing and locating; Comprise shell 1, the lower end of shell 1 is provided with Surface Mount pin 3, and shell 1 is provided with installing hole and guide-localization pin 2; Said guide-localization pin 2 adopts the mode of interference fit to be fitted on the shell 1, and the Surface Mount pin 3 of said connector lower end mounts structure for horizontal surface; Said guide-localization 2 front ends of pinning are tapered configuration.
Among Fig. 2; Guide-localization pin 2 is an interference fit with shell 1, adopts the mode that press-fits shop bolt 2 to be encased in the hole of shell 1, and shop bolt 2 front ends are tapered configuration; Not only be beneficial to the assembling mode that interference press-fits; And be beneficial to when installing and the guide-localization of printed board location hole, and connector lower end Surface Mount pin 3 adopts special-purpose moulding frock to carry out bending and molding, and the positioning reference of bending and molding is the shop bolt 2 on the shell 1; Can guarantee the relative positional accuracy of shop bolt 2 and Surface Mount pin 3 like this; After connector leaned on shop bolt 2 to be installed in the printed board, Surface Mount pin 3 can align the printed board pad, thus the expectation function that the realization Surface-mount connector exempted to adjust when installing.
