Embodiment

See also Fig. 1 to Fig. 3, the electric connector 200 of the utility model better embodiment comprises socket 21 and plug 23.The core of a cable that electric connector 200 can be used for automobile connects.

Socket 21 comprises shell 211 and a plurality of insert-connecting plate 213.Shell 211 is made for insulating material, and it is roughly the square casing of an end opening.Be formed with containing cavity 2110 in the shell 211, the outer wall that is positioned at the middle part of the end face of shell 211 projects upwards and is the stepped of symmetry, thereby is formed with the stopper slot 2111 of a strip and lays respectively at two gathering sills 2113 of stopper slot 2111 both sides in containing cavity 2110.Stopper slot 2111 is separated by baffle plate 2114 with adjacent gathering sill 2113.Be formed with spacing preiection 2115 near on the position of shell 211 1 ends on shell 211 stopper slots 2111 diapires.Shell 211 is provided with the square fixed head 2116 that is used for fixing insert-connecting plate 213 at its end away from openend, offers the fixedly fixing hole 2118 (seeing also Fig. 4) of a plurality of strips of insert-connecting plate 213 on the fixed head 2116.Fixing hole 2118 is in fixed head 2116 extension that tilts, and these a plurality of fixing holes 2118 are arranged in array.Insert-connecting plate 213 comprises the lamellar body 2131 of strip and is formed on the wire connecting portion 2133 of the strip of lamellar body 2,131 one ends.The width of wire connecting portion 2133 is slightly less than lamellar body 2131.Lamellar body 2131 is in the insertion section 2135 that stretches out and be formed with away from wire connecting portion 2,133 one ends.Insertion section 2135 roughly is truncated rectangular pyramids shape, and on its bearing of trend, the radial dimension of insertion section 2135 reduces gradually.Each insert-connecting plate 213 is fixedly installed in the fixing hole 2118 by bonding mode, makes the lamellar body 2131 of insert-connecting plate 213 be positioned at containing cavity 2110, and wire connecting portion 2133 is exposed to outside the shell 211, is used for being connected with external cable.Certainly, insert-connecting plate 213 the modes in the fixing hole 2118 of being fixed on are not limited to bonding, and it also can be engaging or other fixed forms.

See also Fig. 2 to Fig. 4, plug 23 comprises the body 231 of insulation and is arranged at a plurality of holders 233 in the body 231.In the present embodiment, body 231 is square, and it is made by plastic material.Extending to form cantilever 2310 near on the position of body 231 1 ends on body 231 outer walls, this cantilever 2310 is corresponding with the stopper slot 2111 of socket 21, cantilever 2310 stretches out in the middle to be formed with and holds projection 2311, and holding projection 2311 is a sliding bevel (figure is mark not) at it away from cantilever 2310 free-ended surfaces.Body 231 also respectively is formed with a gib block 2313 in cantilever 2310 both sides, and these two gib blocks 2313 are corresponding one by one with two gathering sills 2113 of socket 21.Offer a plurality of square accepting holes (figure is mark not) in the body 231, these a plurality of accepting holes are corresponding one by one with the fixing hole 2118 of socket 21.

Holder 233 is used for clamping insert-connecting plate 213, and it comprises the matrix 2331 that roughly is square, from the jig arm 2333 of extended two the relative strips of matrix 2,331 one ends and the leg 2335 that extends to form from matrix 2331 other ends.Be economical with materials, offer through hole 2336 on the matrix 2331.Matrix 2331 is formed with holding flange 2337 at its outer wall near leg 2335 places, and the size and the accepting hole of this holding flange 2337 are complementary.Holding flange 2337 can be fixed on the sidewall of accepting hole by bonding or other modes, at this moment, have the space between two jig arm 2333 and the accepting hole sidewall, with as the open deformation of two jig arm, 2333 elasticity space, leg 2335 is outside accepting hole extends body 231.Two jig arm 2333 are arranged at intervals with a pair of first clamping projection 2338 and a pair of second clamping projection 2339 on its opposed inside face, wherein the first clamping projection 2338 is positioned at the end of jig arm 2333 away from matrix 2331.Spacing between two first clampings projection, the 2338 and two second clamping projectioies 2339 is less than the thickness of insert-connecting plate 213, and first clamping projection, the 2338 and second clamping projection 2339 all is circular arc.

See also Fig. 4 and Fig. 5, the leg 2335 of plug 23 and the wire connecting portion 2133 of socket 21 can link to each other with two sections external cables (figure does not show) respectively.Plug 23 inserts in the containing cavity 2110 away from fixed head 2,116 one ends from socket 21, each insert-connecting plate 213 penetrates from an accepting hole, the insertion section 2135 of insert-connecting plate 213 compresses first clamping projection, the 2338 and second clamping projection 2339 of two jig arm 2333 successively, two jig arm, 2333 elasticity are opened and clamping insert-connecting plate 213, like this, two sections external cables being connected of socket 21 and plug 23 can be realized electrical communication.Simultaneously, the cantilever 2310 of plug 23 and gib block 2313 are corresponding respectively to be slipped in the stopper slot 2111 and gathering sill 2113 of socket 21, and gib block 2313 is used for the glide direction of correcting cantilever 2310.Spacing preiections 2115 in the limited groove 2111 in the side that holds projection 2311 inclination of cantilever 2310 compress, and make cantilever 2310 that elastic deformations take place, and finally make to hold projection 2311 and by spacing preiection 2115 cantilever 2310 is contained in this stopper slot 2111.Cantilever 2310 elastic deformations recover, and hold projection 2311 and lean with spacing preiection 2115, and plug 23 is fixed in the containing cavity 2110 of socket 21.The free end of pressure holding cantilever 2310 makes cantilever 2310 that deformation take place, and spacing preiection 2115 no longer against holding projection 2311, can be extracted plug 23.

Electric connector 200 of the present utility model only has insert-connecting plate 213 and holder 233 will select for use metal material to make, and the body 231 of socket 21 shells 211 and plug 23 can select for use plastic material to make, and material cost is lower.And the simple shape of insert-connecting plate 213 and holder 233 can process by the mode of punching press, and production cost is also lower.

Insert-connecting plate 213 quantity and the arrangement mode of electric connector 200 of the present utility model can be provided with according to actual needs, and its quantity can be one, also can be a plurality of.The arrangement mode of a plurality of insert-connecting plates 213 is not limited to array arrangement, also can be other arrangement modes, as along the circumferential direction being intervally arranged or the like.Certainly, when the quantity of insert-connecting plate 213 or arrangement mode changed, the quantity of holder 233 and arrangement mode also needed to do corresponding adjustment.And the wire connecting portion 2133 of insert-connecting plate 213 can be exposed to outside the shell 211 fully, also can partly be exposed to outside the shell 211, as long as make things convenient for wiring; In like manner, the leg 2335 of holder 233 also can partly be exposed to outside the body 231.

The quantity of the jig arm 2333 of the holder 233 of electric connector 200 of the present utility model is not limited to two, and it also can form a jaw with the clamping insert-connecting plate for a plurality of jig arm 2333 are spaced, and can realize effect same.The clamping projection can be omitted, and can how rightly perhaps be for a pair of also.In general, the logarithm of clamping projection is many more, and the clamping effect is stable more, and this moment holder 233 and insert-connecting plate 213 for multiple spot contacts, can reduce the generation of the phenomenon that electrically disconnects when insert-connecting plate 213 rocks.

In addition, those skilled in the art also can do other variation in the utility model spirit.Certainly, the variation that these are done according to the utility model spirit all should be included in the utility model scope required for protection.
