Description

Electric connector

The utility model relates to a kind of electric connector, particularly a kind of D type electric connector.

See also Fig. 1, it is a kind of existing D type electric connector, is provided with a pedestal 91, an iron-clad 92 and a plurality of terminal 93; Wherein:

Pedestal 91 is the D type, is covered by a main body 911 and an accessory body 912 to form, and it is provided with the pre-and post perforative jack 913 of two rows, and the jack of main body 911 back segments is broad hole 9131, and the back segment pedestal is provided with convex section 914.

93 one-tenth of terminals are shaft-like, by preceding contact site 931, location division 932 and the pin portion 933 of then being provided with, wherein contact site 931 includes flexible double team sheet 9311, and front end is a horn mouth 9312, thicker shaft-like in 932 one-tenth of location divisions, the leading portion of pin portion 933 is provided with an extrusion recess 9331; Each terminal 93 is installed in the jack 913 of pedestal 91, and location division 932 is installed in broad hole 9131, is than aperture before and after it, so can make terminal 93 be subjected to fastening.

Iron-clad 92 includes fore shell 921 and back cover 922, covers to form, and front end and the rear end by pedestal 91 coats pedestal 91 respectively, again with fore shell 921 and back cover 922 riveteds, so that pedestal 91 is fixing.

There is following shortcoming in existing electric connector:

1, because terminal 93 need have very strong confining force with pedestal 91, so pedestal 92 need be designed to main body 911 and accessory body 912, could be with terminal 93 fastenings.

2, for the tin that prevents to overflow (when the scolding tin tin liquor by 933 overflows of pin portion to contact site 931), the pin portion 933 of terminal 93 need be provided with an extrusion recess 9331, stops tin liquor.

3, iron-clad 92 also need be divided into fore shell 921 and back cover 922, and mutual riveted will be being fixed by the pedestal 91 that main body 911 and accessory body 912 cover.

Main purpose of the present utility model is to provide a kind of cost simple in structure low electric connector.

For the utility model that achieves the above object is taked following measure:

Electric connector of the present utility model comprises: a pedestal and a plurality of terminal, and the compartment of terrain is provided with the jack that two rows are run through up and down on the pedestal, and its upper and lower end face is sealing surface except jack; Terminal is provided with contact site, location division and pin portion, and it is installed in the jack, and location division and pedestal are fixed;

It is characterized in that the location division of each terminal is provided with the clamping part that protrudes to the pedestal outer end, pedestal one ejection formation, the clamping part of its outer wall corresponding terminal is provided with the press section that terminal can't outwards be broken away from, the clamping part of press section fastening terminal.

Wherein, described pedestal is provided with the convex section of broad, and convex section is provided with the groove of corresponding described each clamping part.

Wherein, the location division of described terminal becomes en plaque, and the both sides of the clamping part on it separate with terminal, and front and back ends is connected with terminal; Contact site also is en plaque, is provided with into two elastic arms of a spacing.

Wherein, described two elastic arms are provided with more approaching contact mutually, and contact is provided with flange.

Reaching embodiment in conjunction with the accompanying drawings is described in detail as follows specific structural features of the present utility model:

The accompanying drawing simple declaration:

Fig. 1: the three-dimensional exploded view of existing electric connector.

Fig. 2: the combination section of existing electric connector.

Fig. 3: the combination section of the utility model first embodiment.

Fig. 4: the front view of pedestal among the utility model first embodiment.

Fig. 5: the front view of terminal among the utility model first embodiment.

Fig. 6: the end view of terminal among the utility model first embodiment.

Fig. 7: the combination section of the utility model second embodiment.

See also Fig. 3,4,5 and 6, it is the schematic diagram of the utility model first embodiment, and it includes a pedestal 1, an iron-clad 2 and a plurality of terminal 3, wherein:

The compartment of terrain is provided with the jack 11 that two rows are run through up and down on the pedestal 1, its upper and lower end face is sealing surface except jack 11, and the rear end of pedestal 1 is the convex section 12 of broad, and the two ends up and down of convex section 12 are provided with groove 13 at interval, groove 13 corresponding each jack 11 are provided with axial draw-in groove 15 in the jack 11.

Terminal 3 is en plaque, be provided with contact site 31, location division 32 and pin portion 33, it is installed in the jack 11 of pedestal 1, contact site 31 is provided with into two elastic arms 311 of a spacing, front end is provided with close contact 312 mutually, contact 312 is provided with flange, the both sides fastening of contact site 31 is in draw-in groove 15, stamps out one on the location division 32 and is the clamping part 321 that arcuation protrudes to pedestal 1 outer end, and clamping part 321 both sides separate with terminal 3, before, the rear end is connected with terminal 3, the 33 both sides folding up of pin portion, so that its reinforcement, its tail end connects strip 34, after terminal was packed pedestal 1 into, strip 34 again fractureed.

Iron-clad 2 is provided with fore shell 21 and back cover 22.

During assembling, after the whole row of each terminal 3 minutes two row organizes two socket holes 11 of pedestal 1, from location division 32 pressurizations of groove 13 corresponding terminals 3 of pedestal 1 outer wall, make it form a press section 14 again, press section 14 can't outwards break away from terminal 3 clamping part 321 fastenings of terminal 3; At last fore shell 21 and back cover 22 are coated back riveted mutually from front and back ends with the both sides and the upper and lower side of pedestal 1 respectively.

Pedestal 1 is by clamping part 321 fastenings of press section 14 with terminal 3, and pedestal 1 can integrally formedly penetrate, and need not be divided into two, with simplified construction, reduces manufacturing cost.

The foregoing description, for cooperating existing iron-clad specification designed, so still be designed to the mode of two mutual riveteds, see also Fig. 7, it is second embodiment of the present utility model, be single iron-clad form, pedestal 1 back segment of present embodiment need not established convex section, like this, can get final product with pedestal 1 packing by the single iron-clad 2 of fit, make iron-clad 2 designs simplifications, reduce cost more.Because pedestal of the present utility model is one of the forming.So do not need to rivet mutually and locate pedestal with two iron-clads.

Compared with prior art, the utlity model has following effect:

1, the mutual buckle of pedestal and terminal, so pedestal can be integrally formed, designs simplification can reduce cost.

2, the press section 14 by pedestal 1 can stop that terminal 3 breaks away from, and can have the effect that prevents excessive tin simultaneously.

3, can simplify iron-clad and become one chip, more can reduce cost.

More than narration is to borrow preferred embodiment that architectural feature of the present utility model is described, is not to be used to limit protection range of the present utility model.
