Description

Electronic card coupler

The utility model is a kind of electronic card coupler, especially refers to a kind of be applied to electrically conduct electronic cards internal circuit and extraneous cable, and volume is small and exquisite and have a shading member and can reach the good electronic card coupler that prevents the electromagnetic interference effect.

In current electronics technology with keen competition field, pursue the superior of high-speed transfer and transmission quality, become the common objective of numerous production firms.Existing notebook computer memory capacity deficiency, phenomenons such as outer connection function is not enough, nowadays general is overcome by electronic card coupler and high speed bus connector, therefore, in order to comply with this trend, just constantly develop the electronic card coupler of integrated function at present.Notebook computer all is equipped with electronic card coupler for now, though this has improved the memory function of notebook computer, but, because the steadiness of existing electronic card coupler telecommunication transmitting speed, function and butt joint is still not enough, so its quality of using and the effect auxiliary equipment that all do not catch up with the computer periphery.Be a kind of existing electronic card coupler as shown in figure 11, it is provided with the insulating body 61 that a lengthwise extends, these insulating body 61 1 sides are made as interface 62, an opposite side then is a junction 63, please cooperate with reference to Figure 12 again, be concaved with docking groove 64 on interface 62, docking groove 64 inboards then are provided with a buttcover plate 65 that protrudes, be provided with several grooves 66 towards the outside on these buttcover plate 65 upper and lower plate faces, it connects insulating body 61 near docking groove 64 inboard ends and has formed terminal accommodation holes 67.In addition, in terminal accommodation holes 67, be equiped with several conducting terminals 7, the butt end 71 of these terminals 7 is passed terminal accommodation holes 67 and is extended in the groove 66 of buttcover plate 65, its connection terminal 72 is then protruding to be exposed at outside the junction 63 of insulating body 61, respectively is provided with the earth terminal 73 that end bending is extended at insulating body 61 two ends near 72 places, connection terminal of terminal 7 simultaneously.In addition, as shown in figure 12, electronic card coupler 6 is to connect fixing in the mode of clamping with the exterior region hyte of circuit board 8 and be installed on the shaped as frame support (not shown) by the connection terminal 72 of terminal 7.Moreover when two metallic shield housings 91 of assembling support (not shown) upper and lower both sides cover cap, the oblique extension of two bending ends of the earth terminal 73 of electronic card coupler 6 also contacts with metallic shield housing 91, thereby reaches the purpose of shielding and ground connection.Butt connector (not shown) then inserts in the docking groove 64 of this electronic card coupler 6, utilizes its docking site and the butt end 71 of terminal 7 to be in contact with one another and to realize conducting.

Yet the employed conducting terminal of this existing electronic card coupler is a speed transmission, so its function can not show a candle to the terminal of high-speed transfer.Moreover when existing butt connector docked with electronic card coupler, though there is plurality of conductive terminals to grip each other, if use in the environment of vibration, butt connector then might break away from electronic card coupler, and causes moment to open circuit.In addition, though the upper and lower shield shell of existing electronic cards is a metal material manufacturing, and be used for covering and preventing electromagnetic interference, but, can not have the gap really because of plane contact between electronic card coupler and the upper and lower metal shell, very easily cause the electromagnetism noise of interference to scurry into, the telecommunication transmission is interfered, influence the stability of telecommunication transmission from the gap.Therefore, design a kind of can firmly the butt joint with butt connector, and telecommunication transmits electronic card coupler quickly and easily, this is the major subjects of this case.

Main purpose of the present utility model provides a kind of being connected on the electronic cards and also can electrically connect with butt connector, and the more existing electronic card coupler of its structure is more small and exquisite, and its connection and the more superior electronic card coupler of assembling performance.

Another one purpose of the present utility model is that the electronic card coupler that is provided has a kind of fixture, utilizes this fixture to fix to prevent that it from getting loose or cause loose contact inserting butt connector in this electronic card coupler docking mechanism.

Another purpose of the present utility model provides a kind of shading member, and the shield shell collocation existing by this shading member and electronic cards can make electronic cards have good covering and the ground connection effect.

The utility model electronic card coupler comprises insulating body, conducting terminal etc., wherein convex with docking section on the side appropriate location of insulating body with shrinkage pool shape docking groove, respectively extend suitable length in its docking groove both sides and form elastic arm, on the suitable position of this elastic arm, be provided with grab towards inner bending.In addition, middle part, the bottom surface of insulating body then is provided with the short slot that the docking groove with the docking section connects, this short slot is provided with the projection that is higher than the bottom surface by docking groove one side, utilize this projection to replace whole insulating body bottom to cooperate to come auxiliary electron to fasten with the electronic cards support, and can cut down the segment thickness of electronic card coupler bottom thus, make whole electric connector be the trend of Bao Xiaohua.

In addition, this projection one in the short slot is extended with the button with barb and holds sheet, when butt connector inserts, the grab that utilizes this button to hold the barb of sheet and above-mentioned elastic arm buckles into the corresponding site of butt connector and it is pegged graft firm, prevents that butt connector from getting loose or the purpose of loose contact thereby reach.

Moreover, periphery at insulating body is coated with shading member, the appropriate location at the corresponding insulating body of this shading member top is provided with flange, each suitably extends flange two avris and perk formation shell fragment, when assembling this shell fragment can contact with the existing metallic shield housing of electronic cards, and then reach good shielding and ground connection effect with predetermined conductive path conducting.

Prior art relatively, the utility model not only can provide more solid and reliable but also butt joint easily, has more that shielding properties is good, thin little and the advantage that the telecommunication transmission is stable of volume.
