Description
[technical field]
The present invention relates to a kind of electronic card coupler, refer in particular to a kind of electronic card coupler that can protect conducting terminal.
[background technology]
At present, the employed terminal of electric connector has the trend of densification, to adapt to the needs of market to a large amount of and rapid transmission electronic signal.This densification trend produces sizable impact to the assembling of electric connector terminal, especially for electronic card coupler, its highdensity terminal often requires terminal winding and avoiding because of the improper stressed terminal bending short circuit that causes easily when electrically engaging with main circuit board.Related art is as China's electronic card coupler that No. 02251596.8 patent disclosed, and its conducting terminal is without any protection, therefore with the circuit board group termination process in be subjected to improper external force effect easily and the phenomenon of the warpage that rebounds.
Simultaneously, the increase of transmission speed and conducting terminal density causes telecommunication more seen seriously by the interference of electronic noise in the environment, and the static that electronics is stuck in its surface aggregation when pegging graft also can influence the quality of telecommunication transmission, so the stability of grounding construction to guarantee that telecommunication is transmitted that electrically connects with the motherboard ground path is set on electronic card coupler usually.Related art is as China's electronic card connector that No. 99225457.4 patent disclosed, the earth terminal of its shading member is disposed on wherein between row's conducting terminal, conducting terminal short circuit with contacting of earth terminal takes place in this structure easily, moreover, though its positioner can prevent conducting terminal and produce the bounce-back warpage when butt joint, but structure is complicated, and production cost is higher.
[summary of the invention]
The object of the present invention is to provide a kind of can effectively prevent conducting terminal when pegging graft because of being subjected to improper external force rebound warpage and and the electronic card coupler of shielding plate short circuit on it.
For achieving the above object, the present invention adopts following technical scheme: a kind of electronic card coupler, can be used to electrically connect electronic cards element and circuit board, it is provided with insulating body, on insulating body, form the terminal accommodating district, in this terminal accommodating district, further form the plurality of terminals accepting hole to accommodate conducting terminal in a row, extend before and after terminal accommodation holes respectively at the two ends of this conducting terminal, wherein the rear end of conducting terminal and electronic cards element are electrically conducted, and front end is formed by flat part with from the vertical portion that its end extends to form straight down.Further be coated with shielding plate above the terminal accommodating district, be provided with terminal cap between the flat part of above-mentioned conducting terminal and shielding plate, the bottom surface of this terminal cap forms some holding slots, in order to the flat part of fixed conductive terminals.
Compared with prior art, the present invention has following beneficial effect: the first, and flat part by being arranged on conducting terminal and the terminal cap between the shielding plate prevent the short circuit between conducting terminal and the shielding plate; The second, fix the flat part of conducting terminal by being arranged under the terminal cap holding slot of bottom surface, thereby when preventing effectively that conducting terminal from pegging graft because of being subjected to the improper external force effect warpage that upwards rebounds.

[embodiment]
See also Fig. 1 and Fig. 2, electronic card coupler 1 of the present invention is mounted on the subcard element (not shown) of can powering on the circuit board and electrically pegs graft, and it comprises insulating body 2, terminal accommodating seat 3, be contained in conducting terminal in a row 4 in this insulating body 2 and the terminal accommodating seat 3, be covered in terminal cap 5 on this conducting terminal 4, be covered in shielding plate 6 on this terminal cap 5, be covered in shielding casing 7 on this shielding plate 6 and the insulating body 2 and assembly in the trip mechanism 8 of this shielding casing 7.
See also Fig. 3, Fig. 4 and Fig. 5, form terminal accommodating district 20 on the insulating body 2, in this terminal accommodating district 20, further form the terminal accommodation holes 23 of some lengthwises arrangements to accommodate conducting terminal in a row 4, extend from terminal accommodation holes 23 front and back respectively at the two ends of this conducting terminal 4, wherein the rear end 40 of conducting terminal is electrically conducted with the electronic cards element, front end is made up of flat part 41 and vertical portion 42, wherein flat part 41 extends to form vertical portion 42 straight down at its end, in order to realize and the docking of circuit board.Both ends in terminal accommodating district 20 respectively are provided with screw 21, for electronic card coupler 1 affixed circuit board or other electron component.
Terminal accommodating seat 3 is assembled in the front side in terminal accommodating district 20, it has a lengthwise wall 30, after these lengthwise wall 30 1 side direction, offer accepting groove 31, in this accepting groove 31, form the slit 32 that some lengthwises are arranged, and protrude out the projection 33 that some lengthwises are arranged forward from the opposite side with respect to accepting groove 31 of above-mentioned lengthwise wall 30, form groove 34 between per two projections 33.During assembling, the vertical portion 42 of above-mentioned conducting terminal 4 front ends is accommodated and is immobilizated in the above-mentioned slit 32 and passes slit 32 and extend downwards, and its flat part 41 then is positioned on the slit 32.
Therefore, when electronic card coupler 1 of the present invention is assembled on the circuit board, the terminal cap 5 that covers on the flat part 41 of conducting terminal 4 front ends relies on its holding slots 51 to fix conducting terminal 4, thereby the improper external force effect that makes progress that opposing conducting terminal 4 is subjected to when pegging graft, rely on its earth terminals 60 to be retained on the further above-mentioned improper external force of opposing of structures in the groove 34 of terminal accommodating seat 3 and be covered in shielding plate 6 on the terminal cap 5, thereby prevent that effectively conducting terminal 4 is because of being subjected to these external force effects warpage that upwards rebounds.Moreover the terminal cap of being made by plastic material 5 can prevent contact between them and the short circuit that causes between conducting terminal 4 and shielding plate 6.
