Abstract
The utility model relates to a connector, and particularly relates to an SMT female header connector capable of preventing reverse insertion. The SMT female header connector comprises a cuboid-shaped plastic body and female terminals, wherein the plastic body is provided with a rubber core, the rubber core is provided with a PIN hole and terminal inserting holes, and the female terminals are inserted in the terminal inserting holes of the rubber core. The female terminal is provided with three terminal elastic pieces, wherein two of the terminal elastic pieces are located at the left and right sides of the female terminal respectively, the terminal inserting hole is internally provided with two terminal limiting blocks, and the two terminal limiting blocks are located below the two terminal elastic pieces at the left and right sides respectively. When the female terminal is inserted into the terminal inserting hole normally, the two terminal elastic pieces at the left and right sides are abutted against the terminal limiting blocks respectively. When the female terminal is in the state of a reverse direction, the front ends of the terminal elastic pieces are abutted against the terminal limiting blocks if the female terminal is inserted in the state of the reverse direction, and the female terminal can not be inserted into the terminal inserting hole, thereby being capable of effectively preventing occurrence of reverse insertion of the female terminal, and effectively guaranteeing product functions of the SMT female header connector.

Summary of the invention
The utility model provides a kind of anti-anti-inserted SMT row female connectors at prior art problems.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of anti-anti-inserted SMT row female connectors, comprise the plastic body and the female terminal that are cuboid, described plastic body is provided with the glue core, described glue core is provided with PIN hole and terminal insertion hole, described female terminal is plugged in the terminal insertion hole of glue core, it is characterized in that: described female terminal is provided with three terminal shell fragments, wherein there are two terminal shell fragments to lay respectively at left side and the right side of female terminal, be provided with two terminal guide vane end stops in the described terminal insertion hole, described two terminal guide vane end stops lay respectively at the below of two terminal shell fragments of the left and right sides; When female terminal normally inserts terminal insertion hole, two terminal shell fragments that are positioned at the left and right sides respectively with terminal guide vane end stop butt.
Wherein, described female terminal is U-shaped splicing ear, and described U-shaped splicing ear comprises terminal insertion section and terminal weld part, and described terminal insertion section and terminal weld part are one-body molded; Described terminal insertion section is plugged in the terminal insertion hole of glue core, and described terminal weld part is used for being welded in corresponding circuit board.
Further, described three terminal shell fragments are positioned at the front end of terminal insertion section.
The beneficial effects of the utility model:
A kind of anti-anti-inserted SMT row female connectors that the utility model provides, comprise the plastic body and the female terminal that are cuboid, described plastic body is provided with the glue core, described glue core is provided with PIN hole and terminal insertion hole, described female terminal is plugged in the terminal insertion hole of glue core, described female terminal is provided with three terminal shell fragments, wherein there are two terminal shell fragments to lay respectively at left side and the right side of female terminal, be provided with two terminal guide vane end stops in the described terminal insertion hole, described two terminal guide vane end stops lay respectively at the below of two terminal shell fragments of the left and right sides; When female terminal normally inserts terminal insertion hole, two terminal shell fragments that are positioned at the left and right sides respectively with terminal guide vane end stop butt.When female terminal is in reverse state, if female terminal inserts with this state, the leading section of the terminal shell fragment terminal guide vane end stop of conflicting, female terminal can't be inserted in the terminal insertion hole, can prevent effectively that the anti-inserted situation of female terminal from occurring, and ensures the product function of SMT row female connectors effectively.

Embodiment
For the ease of those skilled in the art's understanding, below in conjunction with embodiment and accompanying drawing the utility model is further described, the content that execution mode is mentioned not is to restriction of the present utility model.Referring to Fig. 3 to Fig. 5, below in conjunction with accompanying drawing the utility model is described in detail.
A kind of anti-anti-inserted SMT row female connectors that the utility model provides, comprise the plastic body 1 and the female terminal 2 that are cuboid, described plastic body 1 is provided with glue core 3, described glue core 3 is provided with PIN hole 4 and terminal insertion hole 5, described female terminal 2 is plugged in the terminal insertion hole 5 of glue core 3, it is characterized in that: described female terminal 2 is provided with three terminal shell fragments 21, wherein there are two terminal shell fragments 21 to lay respectively at left side and the right side of female terminal 2, be provided with two terminal guide vane end stops 6 in the described terminal insertion hole 5, described two terminal guide vane end stops 6 lay respectively at the below of two terminal shell fragments 21 of the left and right sides; When female terminal 2 is normal when inserting terminal insertion hole 5, two terminal shell fragments 21 that are positioned at the left and right sides respectively with terminal guide vane end stop 6 butts.
In the present embodiment, described female terminal 2 is U-shaped splicing ear, and described U-shaped splicing ear comprises terminal insertion section 22 and be the terminal weld part 23 of bending shape that described terminal insertion section 22 is one-body molded with terminal weld part 23; Described terminal insertion section 22 is plugged in the terminal insertion hole 4 of glue core 3, and described terminal weld part 23 is used for being welded in corresponding circuit board.Further, described three terminal shell fragments 21 are positioned at the front end of terminal insertion section 22.
