Abstract
An electric coupler comprises an insulation body with an accommodating groove, a plurality of ground terminals accommodated in the accommodating groove, a signal terminal and a metal casing wrapping the insulation body. The ground terminals and the signal terminal comprise connecting portions and butt-joint portions respectively. The metal casing comprises an upper casing and a lower casing. The lower casing comprises a plurality of ground portions, the ground portions are connected with the ground terminals in butting mode, and a phenomenon of bad earth due to rack of fusion possibly caused by welding is avoided.
Description
[technical field]
The invention relates to a kind of electric connector, especially refer to a kind of electric connector with ground connection effect.
[background technology]
During electronic device works, the capital has intermittently or the continuity electric current and voltage changes, produce electromagnetic interference (Electromagnetic Disturbance, EMI), electromagnetic interference is produced by radiation and traditional approach usually, therefore all suitably ground connection (Grounding), shielding (Shielding) or filtering (Filtering) designs of any electronic equipment reduce electromagnetic interference as far as possible, with the requirement of the electromagnetic compatibility (EMC) that meets electronic equipment.
Low-voltage differential signal (Low Voltage Differential Signal, be called for short LVDS) be a kind of circuit signal of high-speed transfer mass data, be applicable to that usually resolution is higher than on the interface of TFT LCD display unit, optical-fibre communications and electronic switching system of SVGA.The low-voltage differential signal connector of traditional low-voltage differential signal interface standard; the metal shell that comprises insulating body, is contained in the some earth terminals in the described insulating body and coats described insulating body; described metal shell is provided with a ground strip; earth terminal is welded to ground strip; again ground strip is welded on the metal shell; such connected mode influences the ground connection effect through the phenomenon that rosin joint appears in regular meeting.In addition, Chinese patent has disclosed a kind of like this electric connector No. 201766241, it comprises an insulating body, some conducting terminals, some earth terminals and a grounding plate, earth terminal and grounding plate are one-body molded, though such connector ground connection effect stability, but manufacturing process complexity, production cost are too high.
Therefore, be necessary to provide a kind of new electric connector, to address the above problem.
[summary of the invention]
The object of the present invention is to provide a kind of raising ground connection stability, the simple electric connector of manufacturing process.
To achieve these goals, electric connector of the present invention can adopt following technical scheme: a kind of electric connector, comprise insulating body with accepting groove, be contained in some earth terminals, the signal terminal of described accepting groove and the metal shell that coats described insulating body, described earth terminal, signal terminal comprise connecting portion and docking section respectively, described metal shell comprises upper shell and lower house, described lower house comprises some grounding parts, the described earth terminal of described grounding parts butt.
Compared with prior art, the present invention has following beneficial effect: terminal directly with the lower house conducting of ground connection, in raising ground connection effect, it is simpler that the electric connector production technology also becomes, thereby can effectively enhance productivity, and can effectively reduce the production cost of electric connector.

Fig. 2 is the three-dimensional exploded view of electric connector.
Fig. 3 is the three-dimensional exploded view of Fig. 2 electric connector other direction.
Fig. 4 is the contacted schematic perspective view of earth terminal, signal terminal and lower house of electric connector.
Fig. 5 is the cutaway view along A-A line direction among Fig. 1.
[embodiment]
Please refer to Fig. 1 to Fig. 5, electric connector 100 of the present invention comprises insulating body 10, is contained in the metal shell 30 of some earth terminals 20, signal terminal 22 and coated insulation body 10 on the insulating body 10.
Earth terminal 20 comprises the connecting portion 201 and docking section 202 that is contained in accepting groove 124, signal terminal 22 comprises the connecting portion 221 and docking section 222 that is contained in accepting groove 124, wherein docking section 202,222 and butt connector (not shown) electrically connect, docking section 202,222 upper surface expose to accepting groove 124, and connecting portion 201,221 is connected with cable (not shown).
The rear portion of metal shell 30 forms a pair of fixing arm 34 of outstanding outside, insulating body 10 both sides respectively.Fixing arm 34 comprises a pair of shell body 314 of upper shell 31 both sides and a pair of inner housing 324 of lower house 32 both sides.Each shell body 314 has a pair of groove 316, and each inner housing 324 has a pair of elasticity bent sheet 326, and bent sheet 326 fit 316 make upper shell 31 and lower house 32 easier installations.
