Abstract

The utility model relates to a SMD connector, including gluing the shell, glue the top of shell and draw forth more than one binding post, glue the below of shell and arrange the paster pin according to binding post's order, glue the bottom of shell and still be equipped with the reference column, the reference column is used for being positioned SMD connector on the circuit board, the terminal surface size of reference column is adapted to the locating hole on the circuit board, the even distribution in side of reference column is more than one conquassation muscle. Through the setting of above structure, the terminal surface size of selecting the reference column is adapted to the locating hole, and when the locating column slowly passed the locating hole, the conquassation muscle is breakable, and the fracture produces the extrusion force towards the border of locating hole, guarantees that the connector can be pre-fixed in the circuit board for one back process can go on reliably.

Description

Patch type connector

Technical Field

The utility model relates to a SMD connector.

Background

In application, the patch type connector needs to be positioned on a circuit board firstly and then welded with pins. However, since the thickness of the circuit board is thin, the positioning post of the patch type connector is long, and the positioning post of the patch type connector is not matched with the positioning hole on the circuit board, the positioning of the connector and the circuit board becomes difficult, and the patch pin cannot be accurately welded.

Disclosure of Invention

In view of this, an object of the present invention is to provide a surface mount connector having a crush rib on a positioning column, wherein the positioning between the connector and the circuit board is completed by interference fit generated after the crush rib is broken.

In order to realize above purpose, this practicality adopts such SMD connector, including gluing the shell, the top of gluing the shell draw forth more than one binding post, the below of gluing the shell according to binding post's order arrange the paster pin, the bottom of gluing the shell still be equipped with the reference column, the reference column be used for with SMD connector positioning on the circuit board, the terminal surface size of reference column adapt to the circuit board on the locating hole, the even more than one rib of conquassation of distributing in side of reference column. Compared with the prior art, the invention has the beneficial technical effects that: through the setting of above structure, the terminal surface size of selecting the reference column is adapted to the locating hole, and when the locating column slowly passed the locating hole, the conquassation muscle is breakable, and the fracture produces the extrusion force towards the border of locating hole, guarantees that the connector can be pre-fixed in the circuit board for one back process can go on reliably.

Particularly, the free end of the connecting terminal is parallel to the bottom surface of the rubber shell, and the connecting terminal bends for 90 degrees and then enters the rubber shell. Through the arrangement of the structure, the free end of the wiring terminal is parallel to the bottom surface of the rubber shell, namely the circuit board, so that the wiring terminal can be conveniently connected with other parts, the transverse space of the circuit board is fully utilized, and the situation that the wiring terminal extends longitudinally and further the whole system is overlarge in size is avoided.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Detailed Description

As shown in fig. 1, a surface mount connector includes a rubber casing 3, more than one wiring terminal 1 is led out from the upper side of the rubber casing 3, surface mount pins 2 are arranged below the rubber casing 3 according to the order of the wiring terminal 1, a positioning column 4 is further arranged at the bottom of the rubber casing 3, the positioning column 4 is used for positioning the surface mount connector on a circuit board, the end face of the positioning column 4 is adapted to a positioning hole on the circuit board, and more than one crushing rib 41 is uniformly distributed on the side face of the positioning column 4.

The free end of the wiring terminal 1 is parallel to the bottom surface of the rubber casing 3, and the wiring terminal 1 bends for 90 degrees and then enters the rubber casing 3.
