Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, refers in particular to a kind of electric connector that network connects that is used for.

[background technology]

The novel patent announcement of TaiWan, China has disclosed a kind of electric connector M300909 number, the metal-back that it mainly comprises insulating body, plurality of conductive terminals and is assembled in insulating body.Metal-back partly is coated on the interface of insulating body front end, and extends two left and right relative shell fragments in the host cavity of interface two side direction insulating bodies, and this shell fragment has grounding function.When the butt joint electric connector inserts host cavity, shell fragment is subjected to the pushing effect of butt connector and bends distortion, the madial wall of while lateral compression host cavity, for the left and right sidewall of guaranteeing insulating body not by the shell fragment crushing, the common broad of the thickness of sidewall, therefore, the size of whole electric connector is also bigger, this does not obviously meet the requirement of product miniaturization development, so need a kind of improved electric connector to overcome above-mentioned defective.

[utility model content]

The purpose of this utility model is to provide a kind of have grounding function and electric connector simple in structure.

For achieving the above object, the utility model adopts following technical scheme: a kind of electric connector, it comprises insulating body, be coated on the outer shielding casing of insulating body and some conducting terminals that is contained in the insulating body, described insulating body is provided with roof and is positioned at the sidewall at roof two ends, described roof and two side surround the host cavity that butt connector is accommodated in formation one, described shielding casing comprises the side plate that is covered on the sidewall, described conducting terminal is included in the contact site of diagonally extending in the host cavity, sidewall is provided with the mating holes that connects with host cavity, and punch forming can and be stretched into the shell fragment of host cavity by this mating holes on the side plate.

Compared with prior art, the utility model electric connector is by punch forming one shell fragment on the biside plate of shielding casing, but setting ammunition feed sheet extend into the mating holes in the host cavity on insulating body, thereby reaches grounding function, and plays the effect of simplified structure, reduced volume.

Ginseng Fig. 2,3, shielding casing 2 is bent to form through punching press by a metallic plate, and it comprises the top board 21 that is covered in insulating body 1 top, the side plate 22 that is bent to form from top board 21 two ends and the bonnet 23 that is bent to form from top board 21 rear ends downwards downwards.Described side plate 22 is coated on the sidewall 12 of insulating body 1, biside plate 22 is provided with the through hole 221 that connects with described mating holes 121, be provided with a shell fragment 24 in each through hole 221, this shell fragment 24 is inwardly to be stamped to form from these through hole 221 peritremes, it comprises from the parallel connecting portion 241 that extends forward of through hole 221 posterior lateral margins, from the connecting portion 241 terminal kinks 242 that bend and enter in the mating holes 121, the contact site 243 that extends in host cavity 16 from this kink 242 reaches from the contact site 243 terminal free terminals 244 that extend, described contact site 243 is crooked arc, and it protrudes out described boss 122 end faces and stretches in the described host cavity 16.Side plate 22 tops are provided with the button that bends inwards and be buckled in the described groove 112 and hold sheet 25, side plate 22 bottoms are provided with and bend the buckling piece 26 that is buckled in the described draw-in groove 19, in addition, shielding casing 2 is provided with the latch part 27 that is buckled in it at the described groove of correspondence 123 places.Described side plate 22 and bonnet 23 all are extended with some legs 28 that are welded in circuit board downwards, thereby are immobilizated on the circuit board electric connector is stable.

Ginseng Fig. 2,3, terminal module 3 inserts accepting groove 17 and is assembled in insulating body 1 from body 1 rear of insulating, it comprises a matrix 5 and is shaped in plurality of conductive terminals 4 on the matrix 5, described matrix 5 roughly is the wedge shape block structure, its upper surface is provided with the fin 51 of some intervals parallel arranged, and the upper surface of these fins 51 is an inclined plane 52.Each conducting terminal 4 includes and extends matrix 5 forward and be the contact site 41 of predetermined angular through bending and above-mentioned inclined plane 52 and extend the weld part 42 of matrix 5 bottom surfaces downwards.Described fin 51 is positioned at the below of contact site 41, and corresponding one by one with it, and after non-coupling butt connector inserts host cavity 16, this butt connector will compress contact site 41 downwards until being kept out by fin 51, thereby plays the effect of anti-mis-insertion.When terminal module 3 inserts accepting groove 17, the contact site 41 corresponding slots 141 that insert insulating body 1 rear wall 14, enter host cavity 16 then, matrix 5 both sides are provided with some

projections

53,54,55, and corresponding being snapped in the set draw-in groove in accepting groove 17 both sides 171,172,173, so, terminal module 3 is just stable is immobilizated on the insulating body 1.

During assembling, earlier terminal module 3 is assembled in insulating body 1, then shielding casing 2 is packed into from the top of the body 1 that insulate.Before assembling shielding casing 2, earlier with its biside plate 22 outside opened with certain angle, interfere to avoid the shell fragment 24 and roof 11 both sides of insulating body 1, cross roof 11 upper surfaces downwards until shell fragment 24, interior gradually again pressure biside plate 22 is until pasting mutually with two side 12, guarantee that meanwhile side plate 22 is along in the sidewall 12 downslide processes, shell fragment 24 springs in the mating holes 121 smoothly, button is held 25 of sheets and is buckled in the groove 112, last latch part 27 is buckled on the groove 123, so, shielding casing 2 just liptinite be loaded on the insulating body 1.

The utility model electric connector is applicable to occasion less between emptying; because the side-to-side dimensions (distances between two boss, 122 end faces) of electric connector host cavity 16 is the fixed value of industrywide standard; therefore if to reduce to place electric connector about distance; can only reduce the thickness of insulating body 1 two side 12; when the electric connector of prior art docks with butt connector under the less situation of sidewall 12 thickness; the power that is compressed on the sidewall 12 when set earthing device and butt connector juxtaposition metamorphose on it can be damaged sidewall 12 usually; and the utility model electric connector is by punch forming one shell fragment 4 on the biside plate 22 of shielding casing 2; but the mating holes 121 that ammunition feed sheet 24 extend in the host cavity 16 is set on insulating body 1; butt connector inserts host cavity 16 backs by shell fragment 24 clampings and ground connection; shell fragment 24 opens by lateral compression and outside mating holes 121 simultaneously; in said process; between shell fragment 24 and insulating body 1 sidewall 12 without any interference; sidewall 12 can not be subjected to compressing of metal material and damage; space boundary when therefore the thickness of sidewall 12 can be with actual assembled and corresponding reducing; thereby reach reduced volume, realize the purpose of product miniaturization.In addition, the structure of shell fragment 24 and moulding are all simpler, the effect that can play simplified structure and boost productivity.
