Description

Micro connector

The micro connector of the grafting that the relevant a kind of micro connector of the utility model, outstanding reference and being used for install with computer mouse, keyboard etc.

According to the development of present notebook computer, have light, thin, short, little trend, yet, be subject to the volume reason of electronic component itself, can't effectively reduce the thickness of laptop.Moreover the fixing ability of connector is very big for the stability influence of electric signal transmission.Often in the welding process of connector and substrate,, connector can't be aligned with substrate engage, thereby influence welding quality, cause quality defect and cost waste because of lacking the clamping device of connector.In the existing micro connector, for example United States Patent (USP) the 4th, 637, and 669,4,878,858,5,192,228,5,702, No. 271 etc. though all be provided with clamping device, generally is the jointing altitude that can't reduce connector and substrate.Seeing also Fig. 1 is the existing micro connector 6 that is common to computor-keyboard, including one is coated on the shading member 61 outside the insulation shell 60 and forms the members such as grounding elastic part 62 of grounded circuit, wherein be located at the pin 610 on the shading member 61, pass through jointly in the process of tin stove welding at connector and substrate, itself can't provide to align to engage required clamping device.Moreover pin 610 is extended downwards by shading member 61 root edges, and the demand that reduces thickness is not had help.

The purpose of this utility model is: provide a kind of can reduction and circuit board between jointing altitude, make full use of idle space under the circuit board, have good fixing ability, can improve quality bills of materials and micro connector easy to assembly.

The purpose of this utility model is achieved in that in the shading member both sides of this connector and respectively is provided with a recess, extend one at the recess upper limb and fall L shaped pin, partly have the design of pawl and fin to strengthen the conjugation grade of micro connector and substrate in leg end again.In addition, under insulation shell, be provided with a lower cover, except that can still providing preferable capture-effect in the bottom of micro connector simultaneously with other members form firm the joint.And the L shaped pin that falls of this shading member is to be made into integration by the direct punching press of this shading member.

Owing to adopt such scheme, can reduce connector and substrate jointing altitude, and increase computer inside and can utilize the space, and then reduce the required thickness of laptop, the raising quality bills of materials; Also rely on micro connector pin upper inverted tooth device that substrate and it firmly are fastened togather, fin on the pin then can make it reach closely with the pin reception hole of substrate and engage, make whole welding process more smooth and easy, engage steadiness thereby promote the effect of anti-electromagnetic interference, the useful life that increases micro connector and reinforcement.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

See also Fig. 2, Fig. 3, the utility model comprises: insulation shell 1, conducting terminal 2, shading member 3 and lower cover 4, wherein insulation shell 1 has plug surface 10, terminal solder side 11 and stationary plane 12,13 are provided with on plug surface 10 and connector connect inserting groove 101 and several terminal accommodation holes 102 that contains the relative populations terminal of usefulness.Terminal solder side 11 is with respect to plug surface 10 and perpendicular to the substrate setting, but not the existing design that is positioned at the bottom is provided with fixings 330 and its tabling that first caulking groove 110 and second caulking groove 111 are beneficial to shading member 3 in it.And in stationary plane 12, be provided with protruding stops 120, one spacer body 121 that extends is downwards arranged below it, this spacer body 121 is an inclined-plane, can separate first alcove 125 and second alcove 126, be connected with fixture 122 in addition downwards, connector body can be lain on the substrate take place with the situation that prevents to tilt.At fixture 122 the strip conduit 123 of indent design is arranged downwards, and its end have a stop block 124 as and the engagement member that fixes of lower cover 4.

See also Fig. 2 again, shown in Figure 3, shading member 3 is by first surface 30 and from first surface 30 downward end face 33 and the second surfaces 31 that bend, 32 formations in the 3rd surface, second surface 31 reaches and the 3rd surface 32 of its symmetry then is respectively from first surface 30 left, the right side bends and gets, wherein first surface 30 centre are provided with a connector accepting hole, form a receiving space at its rear, can be used for accommodating the connector (not shown) and the insulation shell 1 of butt joint, plurality of conductive terminals 2, and second surface 31 is provided with first clamping part 310, second clamping part 311 and the L shaped pin 312 that falls, the L shaped pin 312 that wherein falls has hangnail 3121 and fin 3120.Lower cover 4 is made of its body panels, back shield 41 and 42,40 on the left and right both wings that upwards bend from body panels respectively, have two build-in pieces 401 and 402 on its right-wing 40, and also there is identical configuration in left wing 42, all can be used to chimeric insulation shell 1.

As Fig. 2, shown in Figure 3, conducting terminal 2 is housed in the terminal accommodation holes 102 of insulation shell 1, simultaneously, has locating piece 112 on the terminal solder side 11, and the positioning function of conducting terminal 2 can be provided.And the combining of shading member 3 and insulation shell 1, shading member 3 can be accommodated in insulation shell 1 on the receiving space 34 along X-direction, wherein first surface 30 fluid-tight engagement are on plug surface 10,31 spacer bodies 121 by first clamping part 310 and stationary plane 12 of second surface block mutually and only cause coming off to prevent shading member 3 from moving in the X-axis direction, again, second clamping part 311 is buckled on the protruding stops 120, can prevent micro connector shading member 3 and insulation shell 1 in the process of constantly plug to separate up and down along Y direction, for the 3rd surface 32, it and second surface 31 be symmetry mutually, it is also identical with second surface 31 that it engages the execution example, moreover, fixings 330 on the end face 33 is mounted in the caulking groove 1 and caulking groove 2 111 of insulation shell 1 after by instrument its being bent, wherein the leading edge both sides on the fixings 330 respectively have a projection 3301 and 3302 cards to end on caulking groove 2 111, can prevent that situation about getting loose from taking place.

As shown in Figure 4, lower cover 4 engages with terminal solder side 11 lower edges of insulation shell 1 by back shield 41, and then the build-in piece 401 and 402 with right flank 40 is buckled in the strip conduit 123, and is fixed on the insulation shell 1.With respect to embedded build-in piece 402, another embodiment is build-in piece 402 ' (as shown in Figure 5) of turning up, and it is fastened in the embedded hole 314, and this design can be bonded together insulation shell 1 and shading member 3 simultaneously.

Again, as Fig. 6, Fig. 7 and shown in Figure 8, it is the schematic diagram that the utility model engages with substrate 5, wherein the L shaped pin 312 that falls on the micro connector engages mutually with the spliced eye 50 and 51 of substrate 5, and rely on hangnail 3121 that micro connector is fixed on substrate, again, fin 3120 makes connector and cooperating of substrate 5 reach more fastening effect at the support function of spliced eye 50.
