Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, refers to a kind of compact electric connector of communication and charge function and volume that is used for having on the mobile phone especially.

[background technology]

Be assembled in the electric connector on the mobile phone,, be equipped with cradle and DC charging groove on it usually, charge at any time, guarantee that mobile phone has sufficient supply of electric power for mobile phone for adapting to the characteristics that mobile phone is convenient for carrying.

Existing connector all is provided with the conducting terminal that is used for transmission signal, the connection point terminal that is used to charge and DC charging terminal usually.The charging slot and the connector plastics housing of accommodating the DC charging terminal are one-body molded, adopt this kind structure, owing to consider the requirement of plastics molding process, plastic casing should have certain thickness, therefore the volume of connector can't effectively reduce, in the time of on being assembled into mobile phone, also difficulty further reduces the mobile phone volume.And,, more can not satisfy the compact development trend requirement of present mobile phone if clad metal housing more then will cause the connector integral thickness to increase because existing connector, can't prevent extraneous noise only by plastic overmold disturbs.

[author content]

The utility model purpose is to provide a kind of noise that prevents to disturb, and volume is frivolous, helps the electric connector that the mobile phone overall volume is dwindled.

For achieving the above object, the utility model is by the following technical solutions: this electric connector is in order to realize signal transmission and charge function, comprise insulating body, signal terminal, charging terminal group and coated insulation body shielding casing, wherein insulating body is longitudinal, which is provided with accepting groove, charging end stroma and the assembly hole of accommodating signal terminal and charging terminal group respectively.Shielding casing coated insulation body forms a charging slot, the charging terminal group that is housed in the charging slot comprises first charging terminal and second charging terminal, first charging terminal is loaded in the stroma of charging end, comprise first connecting portion and first contact site, second charging terminal is loaded in the assembly hole, comprises second contact site and holding section.

Compared to prior art, charging slot of the present utility model is cooperated by insulating body and the shielding casing that covers outward and forms, the charging terminal assembling is located in this charging slot, thereby can reduce the thickness of insulating body greatly, and then reduce the volume of whole connector, and can prevent effectively that extraneous noise from disturbing.

[embodiment]

Please refer to Fig. 1, shown in Figure 2, the utility model electric connector 100 comprises insulating body 1, shielding casing 2, signal terminal 3 and charging terminal group 4.Wherein, insulating body 1 is approximately longitudinal, comprise diapire 15, sidewall 16 and be connected diapire 15 and sidewall 16 and with above-mentioned both all become the connecting wall 17 of miter angle.In addition, also comprise several accepting grooves of accommodating signal terminal 3 10 on the insulating body 1.The end setting that insulating body 1 is not established accepting groove 10 is accommodated the charging end stroma 13 of first charging terminal 40 and is accommodated the assembly hole 14 of second charging terminal 41, and these charging end stroma 13 sides are offered an opening 131.Insulating body 1 is being gone up some fixture blocks 18 that distribute with diapire 15 opposing top (not label), and sidewall 16 is provided with a projection 19 with roof.

Shielding casing 2 is one-body molded by metal material, is coated on insulating body 1 periphery, in order to cover accepting groove 10, charging end stroma 13 and assembly hole 14.Shielding casing 2 comprises basal surface 20, side surface 21, top surface 22 and is connected surface 23, this connection surface 23 connects basal surface 20 and all becomes miter angle with side surface 21 and with said two devices, also distribute on shielding casing 2 top surfaces 22 for corresponding fixture block 18 on the insulating body 1 insert hold hold mouthfuls 28, top surface 22 is provided with a card with side surface 21 connecting places and ends the breach 27 of above-mentioned projection 19 to prevent that insulating body 1 from forwards sliding.Shielding casing 2 is provided with near ends that connect surface 23 and extends internally supporting the elasticity stopping plate 24 of insulating body 1, and shielding casing 2 basal surfaces 20 both sides are respectively established one and are held in and hold pin 25 in the circuit board (not shown).This connection surface 23 is coated on insulating body 1 connecting wall 17 peripheries, and the basal surface 20 of shielding casing 2, connection surface 23, side surface 21 and top surface 22 are enclosed to form a charging slot 26 of accommodating DC charging plug 7 (see figure 3)s with the charging end stroma 13 of insulating body 1.

Charging terminal group 4 comprises first charging terminal 40 and second charging terminal 41 that is housed in the charging slot 26 (Fig. 3 shows), wherein, first charging terminal 40 comprises tabular first connecting portion 401, bends and horizontally extending first weld part 403 from first contact site 402 of first connecting portion, 401 1 end projectioies with from first connecting portion, 401 other ends, first connecting portion 401 of first charging terminal 40 is held in the lateral openings 131 of charging end stroma 13 by card thorn (not label), and first contact site 402 protrudes charging end stroma 13 lateral openings 131.Second charging terminal 41 is housed in the assembly hole 14 of insulating body 1, comprise second connecting portion 411, symmetry be convexly equipped with on second connecting portion 411 and be held in insulating body 1 assembly hole 14 inwalls holding section 412, extend through second contact site 414 of assembly hole 14 forward and from second connecting portion, 411 other ends bendings and horizontally extending second weld part 413, this second contact site 414 is a column from second connecting portion, 411 1 ends.
