Description

Electric connector

Technical field

The utility model relates to a kind of connector that two wiring boards are linked together, and is used for computer, mobile phone, digital camera, PDA, MP3 etc.

Background technology

The spacing of BTB (wiring board is to wiring board) series of products terminal is many more than 0.4 millimeter at present, the male and female product cooperates highly also more than 1.2 millimeters, still can't develop littler thinner product, to be present electric connector structure easily come off when connecting littler more thin product and terminal between contact unreliable, can't satisfy the development trend of electronic product.

Summary of the invention

In order to overcome above-mentioned defective, the utility model provides a kind of electric connector, and this electric connector can adapt to well between littler, thinner wiring board and connect, and adapts to this that present electronic product is little, the development of thinning.

The utility model for the technical scheme that solves its technical problem and adopt is: a kind of electric connector, comprise chimeric public affairs mutually, maternal body, public body comprises public plastic cement main body, be located at the conducting terminal on the public plastic cement main body, maternal body comprises female plastic cement main body, be located at the conducting terminal on female plastic cement main body, public plastic cement main body two ends are installed with public fixed iron piece respectively, the one side of the public dorsad plastic cement main body of public fixed iron piece forms protuberance, female plastic cement main body two ends are installed with female fixed iron piece respectively, female fixed iron piece forms recess towards the one side of female plastic cement main body, protuberance just can place recess with mating, and is public like this, one protruding one recessed structure of junction, maternal body two ends makes it strengthen confining force in the back that plugs each other;

Female plastic cement main body transverse sides is established female side projection, be provided with female middle part projection laterally, female side projection and female middle part projection are spaced apart, the end face of female middle part projection extends outside both sides, form cover plate, protruding two facades in female middle part under the cover plate laterally form female recess respectively, vertically wrap up on female side projection and be provided with conducting terminal, conducting terminal one termination portion is exposed to the outer facade of female side projection, the other end vertically is wrapped in to enter in female recess after female side projection and makes progress, to female recess outside sweep, bend forms first at interval, two salient points, described first, two salient points contact at female recess inner face respectively, it is downward again to be in the outer conducting terminal head of female recess after the bending, crooked in female recess, bend forms the 3rd salient point, the 3rd salient point is relative with facade in female side projection, wraps up the conducting terminal that is in facade top in female side projection again and forms the 4th salient point towards female middle part projection protrusion;

Public plastic cement main body side laterally is provided with public side projection towards the one side of maternal body, public side projection just can place between female side projection and the female middle part projection, vertically wrap up on the public side projection and be provided with conducting terminal, conducting terminal one termination portion is exposed to the outer facade of public side projection, public side convex top forms the 5th salient point towards the outer facade of female side projection, after this combination of male and female, the 5th salient point is stuck under the 4th salient point, thereby the 3rd salient point presses the reliability that the conducting terminal of facade in the public side projection is strengthened the contact of male and female body upper terminal.

Female plastic cement main body both lateral sides limit is respectively equipped with female side projection, and female middle part bulge clearance is between two female side projectioies.

Public plastic cement main body dual-side laterally is provided with public side projection respectively towards the one side of maternal body, and two public side projectioies just can place between corresponding female side projection and the female middle part projection.

Conducting terminal and public plastic cement main body are one-body molded, and the conducting terminal bared end head on the public body is ligulate.

The beneficial effects of the utility model are: the male and female body uses the male and female fixed iron piece respectively, this physical efficiency of male and female is fixed on wiring board, the FPC (soft arranging wire) better, can effectively prevents on business, maternal body undercapacity causes phenomenons such as the scolding tin pin comes off, loose contact;

The male and female body uses the male and female fixed iron piece respectively, and male and female iron plate cooperation place is one protruding one recessed convex closure clamping structure, makes the male and female iron plate strengthen confining force to inserting the back, prevents that it from separately causing the open circuit phenomenon because of the confining force deficiency makes the male and female body;

Adopt covering plate structure on the maternal body, make the conducting terminal can be bent next time, can prevent effectively that the male and female body is bad from extracting of stepmother's body conducting terminal to splitting at cover plate;

Maternal body conducting terminal adopts the convex closure mode, i.e. the 4th salient point, public body adopts protruding glue, i.e. the 5th salient point (extensible the 5th salient point that is wrapping to of conducting terminal, better conduction contact point is arranged like this) between the male and female body, to not only having strengthened the confining force between the male and female body after inserting, also can prevent the outwards ejection of public property product simultaneously, thereby strengthen the reliability that contacts between conducting terminal on the male and female body;

Conducting terminal and public plastic cement main body are one-body molded, and the terminal head is the ligulate structure, can position with mould in integrally formed process like this, thereby prevent that the conducting terminal beat from causing loose contact.
