[technical field]
The invention relates to a kind of electric connector, relate in particular to a kind of heavy board-like electric connector that is provided with reference column.
[background technology]
Along with the specification standardization gradually of electric connector, it is obvious that tool is got in the competition of cost, processing under the certain situation of material the manufacturing cost dominate.The insulating body of the electric connector on the market is plastic cement material now, is got by mould molding.A kind of electric connector that Chinese patent discloses for CN2562410 number; Can organize and be located on the printed circuit board (PCB); It comprises insulating body and plurality of conductive terminals; Wherein insulating body can be organized the edge that is located at printed circuit board (PCB); It comprises the lengthwise main part, by main part protrude out forward can be used to cooperate with butt connector and in be provided with some accepting grooves the docking section, be located at the guidance part at main part longitudinally two ends, the rear portion that extends back by main part, by each guidance part protrude out downwards and extensible first cylinder that passes corresponding hole on the printed circuit board (PCB) and by the rear portion protrude out downwards can with second cylinder of corresponding hole secure fit on the printed circuit board (PCB); Conducting terminal is housed in the insulating body, and each conducting terminal comprises the contact site in the accepting groove that can be housed in insulating body; Wherein, insulating body also comprise be located in it and respectively with the corresponding perforate of above-mentioned first and second cylinder, these perforates and each self-corresponding first cylinder or the arrangement of second cylinder are in a straight line.The cylinder of this structure can still, form wedge angle because the mould that moves horizontally passes the part of opening in the junction of cylinder by the mold injection molding that moves horizontally; The processing of unfavorable mould; And the corners split pole of mould is fragile, and die life is short, makes troubles to production.
Given this; Be necessary to provide a kind of new electric connector to solve because the mould that moves horizontally passes the part of opening to form wedge angle in the junction of cylinder, the processing of unfavorable mould, and the corners split pole of mould is fragile; Die life is short, the problem of making troubles to production.
[summary of the invention]
Therefore, the technical problem that the present invention will solve is that the part that the mould that moves horizontally passes opening forms wedge angle in the junction of cylinder, the processing of unfavorable mould, and the corners split pole of mould is fragile, and die life is short, the problem of making troubles to production.
Electric connector of the present invention; Comprise insulating body; This insulating body comprises base portion, the installation portion that protrudes out backward of this base portion and the reference column that protrudes out of this installation portion certainly certainly downwards, and this base portion and reference column corresponding section are provided with the groove that penetrates this base portion forward, and the orthographic projection of reference column on this base portion falls into groove fully; Wherein, the reference column front portion is provided with a short slot near a side-walls of groove.
Compared with prior art, the reference column front portion of the insulating body of electric connector of the present invention is provided with a short slot near a side-walls of groove, and the part that makes the mould that moves horizontally pass opening reaches the short slot the inside in the reference column epirelief; Can not form wedge angle; Effectively solved because the mould that moves horizontally passes the part of opening and formed wedge angle in the junction of cylinder, the processing of unfavorable mould, and the corners split pole of mould is fragile; Die life is short, the problem of making troubles to production.

[embodiment]
Please referring to figs. 1 through shown in Figure 6, electric connector 100 of the present invention comprises insulating body 1, is assembled in conducting terminal 2 in the insulating body 1, fixedly electric connector is in printed circuit board (PCB) 200 upper fixing elements 3.
Wherein, Insulating body 1 is the edge that can be assembled in printed circuit board (PCB) 200; It comprises base portion 10, from base portion 10 protrude out forward can in order to cooperate with butt connector and in be provided with a plurality of accepting grooves 112 hyoplastron 11, be positioned at the guidance part 12 at hyoplastron 11 two ends, from installation portion 13 that base portion 10 protrudes out backward, protrude out downwards and the extensible fixed part 17 that passes the reference column of corresponding hole on the printed circuit board (PCB) 200 and be arranged at base portion 10 two ends from installation portion 13, on the fixed part 17 fixation group be equipped with fixture 3 fixedly electric connector on printed circuit board (PCB) 200.
The hyoplastron 11 of accommodating conducting terminal 2 docking sections 21 is provided with a breach 110 with hyoplastron 11 separated into two parts, docks different butt connectors respectively, is respectively equipped with fool proof piece 114 on two parts of hyoplastron 11 and cooperates butt connector to insert with guidance part 12.
On the installation portion 13 that base portion 10 protrudes out backward, protrude out downwards and the extensible reference column that passes corresponding hole 201 on the printed circuit board (PCB) 200; Reference column comprises first reference column 14 and columniform second reference column 15 of elliptical cylinder-shape; This first reference column 14 and second reference column 15 are respectively equipped with a short slot 18 near said base portion 10 opposite external side; The part that makes the mould that moves horizontally pass opening reaches short slot 18 the insides in the reference column epirelief; Can not form wedge angle, first reference column 14 and second reference column 15 are provided with hole 201 interference engagement of fin 141,151 and printed circuit board (PCB) 200, strengthen fixing intensity.
Conducting terminal 2 comprises the holding parts 20 that is immobilizated in base portion 10, stretched to by these holding parts 20 1 ends that hyoplastron 11 is exposed to be assembled in the docking sections 21 of accepting groove 112 and by the outward extending connecting portion 22 of these holding parts 20 other ends, and this connecting portion 22 is provided with a bending elastic portion 23.Exposed docking section 21 is connected with butt connector; Connecting portion 22 is welded on the printed circuit board (PCB) 200; Elastic portion 23 helps connecting portion 22 smooth being welded on the printed circuit board (PCB) 200.
Mould comprises the front mould and back mould that relatively moves; When shaped article; Front mould breaks away from product with back mould horizontal opening, and in actual production process, the structure on the product can be perpendicular with the direction that the back mould moves horizontally with front mould; In design process, adopt the mode of slide block or punching to solve these problems.Yet; When making insulating body 1 of the present invention; In order to practice thrift cost; Make things convenient for processing mold, insulating body 1 in the present invention will be employed in position corresponding with reference column on the base portion 10 and offer the use that groove 16 replaces slide blocks, be inserted into the reference column moulding that combines with back mould by front mould by groove 16.But, excessive in order to prevent groove 16, influence assembling effect or increase product appearance size, and make the size of groove 16 just identical with the projected area of reference column on base portion 10.And this reference column is circular, and front mould wedge angle occurs in the place that combines with the back mould, so on reference column, offer a short slot 18, makes front mould can be recessed into 18 li of short slots with the place that the back mould combines, and effectively prevents the formation of front mould wedge angle.
