Embodiment

For ease of further understanding feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing.

See also Fig. 1 to shown in Figure 5, the utility model provides a kind of electric connector, and it mainly respectively has the electronic unit 3,4 (as shown in Figure 4) of conducting

strip

31,41 in order to two of conductings, and these two

electronic units

3,4, circuit board for example is on one, is crimped on this electric connector once relatively.Wherein, this electric connector comprises an insulating body 1 and a conducting terminal 2.

This insulating body 1 comprises: the top, the

diapire

11,12 that respectively have opening 111,121, be connected in two sidewalls 13,14 between this top, the

diapire

11,12, be connected between this two sidewall 13,14 and be roughly parallel to the dividing plate 15 of described roof 11 or diapire 12, and the most guide grooves 16 that are arranged at the adjoiner of described two sidewalls 13,14 and dividing plate 15 tops, bottom surface respectively.One end of wherein each this guide groove 16 (in order to embed the arrival end of conducting terminal 2) also can form an enlarging 161, and so as to more successfully embedding described conducting terminal 2.

This conducting terminal 2 comprises: one roughly is the connecting portion 20 of C shape, a pair ofly give from these connecting portion 20 two ends that horizontal-extending and side also respectively have most interference parts 211 symmetrically up and down backwards, 221

matrix

21,22, a pair of respectively from this matrix 21 respectively, 22 free ends give up and down the elastic arm 23 that extends towards oblique the place ahead symmetrically, 24, a pair of respectively from this elastic arm 23 respectively, 24 free ends give up and down the contact site 231 of arc bending shape extension symmetrically, 241, a pair of respectively from this contact site 231 respectively, 241 free ends give extending symmetrically up and down the engaging arm 25 of (or towards the extension of oblique below) down, 26, a pair of respectively from this engaging arm 25 respectively, 26 free ends give up and down extending backwards symmetrically

colludes arm

27,28, and a pair of respectively from respectively this

colludes arm

27,28 free ends give the stop section 271 of side direction protrusion symmetrically, 281.Connecting portion 20 wherein and this are between the

matrix

21,22, forming one can be corresponding to the grasping part 201 of described dividing plate 15, this roughly is the blind end of an end for being sealed by described connecting portion 20 of the grasping part 201 of U shape, and the other end is then for using the open end that enters for gripped object.

See also Fig. 1,4, shown in 5, this of this conducting terminal 2 is to

matrix

21,22, respectively this interference part 211 of its both sides, 221 respectively these guide grooves 16 corresponding to insulating body 1, so as to guiding respectively this interference part 211,221 are embedded in the corresponding guide groove 16, feasible respectively this interference part 211,221 can also interfere in the inwall of respective guide slots 16, at this moment: the dividing plate 15 of (one) insulating body 1 is held in the grasping part 201 of conducting terminal 2, (2) this of described conducting terminal 2 is to

matrix

21,22 are contacted with the top of dividing plate 15 respectively, the bottom surface, (3) this is to

elastic arm

23,24 together with its contact site 231,241 and respectively protrude from described top, diapire 11, respectively this opening 111 of 12,121, with can be as Fig. 4, electrically be contacted with this two electronic unit 3 as shown in 5 respectively, respectively this conducting strip 31 of 4,41, (4) because this is to stop section 271,281 width is greater than described top, diapire 11, respectively this opening 111 of 12, therefore 121 width, this stop section 271 respectively, 281 can be pushed up, diapire 11, the restriction of 12 inner faces and can't deviating from.

Aforesaid the utility model structure, on described two

electronic units

3,4 one, when being crimped on the utility model electric connector relatively once, because its two

matrix

21,22 is contacted with dividing plate 15 tops, the bottom surface of insulating body respectively, therefore the vertical direction strength of this upper and lower crimping is that mean allocation bears for whole dividing plate 15; And respectively this

matrix

21,22 also gives the horizontal direction embedding and interferes in the respective guide slots 16 of insulating body 1 by its interference part 211,221, therefore no matter the crimping number of times is many again, use is of a specified duration again time, the interference part 211,221 of this conducting terminal 2 will not can the inwall of scratch guide groove 16, and can avoid the loosening phenomenon of conducting terminal 2.Like this, the structure steadiness between described conducting terminal 2 and the insulating body 1 will be tending towards best, and the electrical contact position when reaching crimping is unlikely the effect of running away extremely.

Again because two free ends of this conducting terminal 2, respectively has described stop section 271,281, and respectively the width of this stop section 271,281 is also greater than respectively this opening 111,121 of this insulating body top,

diapire

11,12, so as to make respectively this

elastic arm

23,24 when the reverse resilience in not crimping, can be subjected to the restriction of described top, diapire 11,12 inner faces and be unlikely excessive resilience, relatively, can make

elastic arm

23,24 positions of this conducting terminal 2 can not run away because of resilience.

The utility model electric connector can also can affect this respectively this arm body to stop section 271,281 displacements (that is: always being connected to each position between the stop section by elastic arm) at its conducting terminal 2, further be pre-stressed to allow this to stop section 271,281 flexibly collude in described top respectively, the inner face of

diapire

11,12 and locating, so as to making that respectively this has the

elastic arm

23,24 of contact site 231,241, can accurately electrically be contacted with respectively this conducting

strip

31,41 of described two

electronic units

3,4 because of this location.

In sum, a kind of electric connector provided by the utility model, the structure steadiness that really can solve prior art is not good, easy loosening, and electrical contact position defective such as be easy to run away, belong to a utility model product with height practical value in fact, enhancement on the tool effect meets the application important document of novel patent.

Yet, the above is of the present utility model one preferable feasible embodiment, rather than is used for limiting claim of the present utility model, the equivalent structure that every utilization the utility model specification and accompanying drawing content are done changes, and all should be contained in the claim of the present utility model.
