Embodiment
The utility model be by reed be laterally slid into groove and ensure will not longitudinally come off at the same time laterally be not easy shift come
Realize that electrical connection is fixed.The embodiment of present invention electrical connection fixed structure is described in detail below in conjunction with the accompanying drawings.
Embodiment one
A kind of the first embodiment for being electrically connected fixed structure of the present invention is as shown in Figures 1 to 4.The electrical connection is consolidated
Determining structure includes public connector and female connectors, its public connector mainly includes a reed.The reed has fixed part 11, engaging
Portion 12 and contact part 13, its expanded view is as shown in Figure 1, as shown in Fig. 2, holding section 12 and the bending of contact part 13 after bending shaping
Locate rounding angle.Its fixed part 11 is a rectangle, and 11 short side of fixed part connects with the upper bottom of the holding section 12 of isosceles-trapezium-shaped, is touched
Head 13 is also isosceles trapezoid in unfolded state, and the trapezoidal bottom of holding section 12 connects with the trapezoidal bottom of contact part 13, always
For, holding section 12 and contact part 13 are symmetrically disposed on fixed part both ends.Above-below direction herein refers to past from contact part
The direction of fixed part is upward, otherwise in downward direction.After reed bending shaping, holding section 12 is vertical with 11 face of fixed part, card
Conjunction portion 12 and the junction rounded corner of contact part 13 form obtuse angle, facilitate the upward compression of contact part 13, contact part 13 is divided
Pressure portion 131 and the afterbody 132 that is upturned for arcwall face prominent downwards.Pressure portion 131 arrives the vertical range of fixed part 111
More than the height of holding section 12, the distance of afterbody 132 to fixed part is more than or equal to the difference in height of holding section and pressure portion.
Such as Fig. 4, reed can be welded on printed circuit board (PCB) 1 by inserting or surface-pasted mode.Female connectors include
Metal area 14, metal area are located at the bottom surface of groove 15, the cross sectional shape size of groove 15 is consistent with holding section 12, then groove 15
Depth be equal to holding section 12 height, reed from a side opening of groove 15 slip into when, to make reed smoothly slip into groove 15, pressure
Power portion 131 can be subject to metal area 14 extruding produce deformation, because contact part 13 originally for trapezoidal and its width from holding section
12 intersections are gradually reduced, and therefore, when contact part 13 produces deformation, pressure portion 131 is up moved by the extruding of metal area 14,
Afterbody 132 moves up therewith, and the width of pressure portion 131 and afterbody 132 still remains less than or equal to groove 15 in its equal-height position
Width.The width of holding section 12 reduces from bottom to top, correspondingly, width increases the structure on 15 both sides of female connectors groove from bottom to top
Add, holding section 12 is vertically moved and is limited, therefore, reed and female connectors can not be longitudinally separated.
Because of pressure portion 131 and the interaction force of metal area 14, thus reed is not easy in transverse shifting, while because of holding section
12 with Qian He of groove 15, reed cannot longitudinally be taken out, ensure the stability connected.The design of afterbody 132 can be easy to reed
Smoothly slip into and skid off in metal area 14.
Embodiment two
As shown in Figures 5 and 6, embodiment two and the main distinction of embodiment one are, the holding section 22 of embodiment two is
Relatively long side, and using with fixed part 21 and the line at two intersection midpoints of contact part 23 as symmetry axis axial symmetry, holding section 22 with
The intersection of fixed part 21 is shorter than its intersection with contact part 23.Correspondingly, the section of the groove 25 of female connectors is also convex six side
Shape, and shape size is consistent with holding section 22, the length of groove 25 is as the length of fixed part 21.21 both ends of rectangle fixed part
Holding section 22 and the contact part 23 of hexagon are symmetrical arranged, holding section 22 is vertical with 21 face of fixed part, holding section 22 and contact part
23 rounded corners connect, and contact part 23 includes and is downwardly projected pressure portion 231 and the afterbody being upturned 232, each portion of contact part 23
Partial width is consistent, equal to the base width of intersecting therewith holding section 22.The depth of groove 25 is less than pressure portion to fixed part
Height, thus when reed is slipped into groove 25, pressure portion is subject to the extruding of metal area 24 to deform and move up, with pressure portion
232 height of afterbody that 231 deformations are moved up and moved up is no more than the height of the widest part of holding section 22, therefore contact part 23 can be smooth
Slide in or out groove 25.When reed is in groove 25, groove 25 engages with holding section 22, and holding section 22 is subject to groove 25
Both sides width becomes most limitation from bottom to top, and pressure portion 231 is contacted with the extruding of metal area 24, and reed is equal in transverse direction and longitudinal direction
Fixed.
Embodiment three
As shown in Figures 7 and 8, implementation three and the main distinction of embodiment two are that the shape of its holding section 32 is type
Shape, correspondingly, the cross sectional shape size of the groove 35 of female connectors are consistent therewith, and the length of groove 35 is consistent with fixed part 21,
Holding section 33 is additionally provided with catch 36 in embodiment three, and catch 36 stretches out at convex shape change width, and catch 36 is close to holding section
32 near-end is parallel with fixed part, extends downwardly and is contacted at back bending and back bending with contact part 33 afterwards.When reed slips into groove
After interior, holding section 32 is chimeric with groove 35, and the width of convex shape holding section 32 has a mutation from bottom to top, and 35 both sides of groove
Female connector structure carries out stop limitation to the latter half of the wider width of its type and catch 36, thus the two can not be longitudinal
Separation, the pressure portion 331 of contact part 33 are contacted with the extruding of metal area 34, reed is not easy transverse shifting, the afterbody of contact part 33
332 height being upturned are no more than the height at convex shape change width, 33 each several part width of contact part and metal area 34
Equivalent width, catch 36 because contact part 33 deformation or only move up, if but catch 36 be subject to female connectors because moving up
The extruding of structure then can the rearwardly 332 directions slip on contact 33.
With the electrical connection fixed structure of above-mentioned three kinds of embodiments of the utility model, pass through holding section and the card of groove
Close can ensure the first connecting portion part and second connecting portion part longitudinal direction combining closely, and be the characteristics of holding section comprising one by
Under part that up width diminishes, while laterally difficult to slide, electrical connection is allowed to by the property of reed elastically deformable
Fixed structure design is simple, install and uninstall it is simple and convenient, without extra structural member.In addition the sky of occupancy is also greatly saved
Between volume, for reduce replaceable component size provide convenience.
It should be noted that the utility model is not limited to above two embodiment.In those skilled in the art institute
In the knowledge possessed, the scope of the utility model is belonged to many variations that it is made.
