About this novel aforementioned and other technology contents, characteristics and effect, in the detailed description of the preferred embodiment of following cooperation Figure of description, can clearly present.
This novel surface is installed first preferred embodiment of open type clipping device, as Fig. 5 and shown in Figure 6, the clipping device of this case includes installed part 61, reaches clipping part 62, and installed part 61 is to supply to be surface mounted on a slice circuit substrate, in advance Gui Hua a strip connection pad position.For the purpose of explanation, installed part 61 is divided into the adsorption section 613 that is positioned at central authorities at this, and be formed on adsorption section about 613 two opposite distolateral first basic segment 611 and second basic segments 612, and the line direction that defines two basic segments 611,612 is a length direction.Adsorption section 613 is the planes with a certain size, the usefulness that suction nozzle 8 absorption are moved during for mounted on surface.
Clipping part 62 in this example then comprises two groups of first and second gripping sections 621,624, each gripping section 621,624 is parallel to two opposite distolateral 629 of length direction by basic segment 611,612 respectively and extends upward and form, respectively has one towards the elastic arm 623 who extends away from first and second basic segment 611,612 directions, make that per two corresponding gripping sections 621,624 are interlaced, and alternate directions all is by the direction of adsorption section 613 towards the left and right sides, presents symmetrically with identical alternate directions, non-mirror image.In this example by gripping section 621,624 mutually towards another gripping section 621,624 are bent to form limiting section 622, as shown in Figure 6, this moment, length direction was the direction along the turnover paper, and when carrying out projection perpendicular to length direction downwards by graphic top, can the downward projection from graphic left side limiting section 622 shown in dotted line, to overlap with the projection section of right side limiting section 622, the metallic plate or the wire rod that make any insertion, must force each elastic arm 623 to be out of shape backward earlier, just can enter, and allow elastic arm 623 that elastic-restoring force is provided and urgent clipping enters thing by the position of clipping.
Definition according to Hooke's law, when a gripping section is stressed, and stress value is less than yield strength, then distortion of materials belongs to strain, and after load shedding, gripping section can be returned to original shape, in design, it is the limit of a stressed size that yield strength is taken as, and the angle of elastic arm's bending diminishes and can make yield strength increase, and makes this novel last open type clipping device have better clipping effect.
As shown in Figure 7, the last open type clipping device that sees through this example carries out the installation of crown cap 7, and the sidewall 72 of crown cap 7 is offered the block button hole 71 that is formed with corresponding each gripping section 621,624, when sidewall 72 inserts gripping section 621,624 clip positions, gripping section 621,624 can be strutted by sidewall 72 earlier, up to the position that touches block button hole 71, gripping section 621,624 can be detained because of elastic recovery and live crown cap 7 admittedly, and the yield strength of gripping section 621,624 increases because structural angle changes, therefore, crown cap 7 will fully be fixed.
Must emphasize at this, the alternate directions of gripping section as shown in Figure 8, every group of corresponding mutually gripping section 621,624 alternate directions are shown in dotted line, gripping section 621 is parallel with another group gripping section 624 alternate directions 620, such structure can make when carrying out the barrel plating operation, because alternate directions unanimity, feasible this novel clipping device gripping section 621 to each other, 624 when corresponding, can part conflict mutually, therefore be not easy to coincide and tied up in knots mutually, make rate of finished products and output thereby lifting, product can be entangled with mutually easily when stacking one place is finished in manufacturing yet and can't be used, up to the strip of packing into dish into.Certainly, if with two groups of gripping sections in the longitudinal direction spacing distance be designed to differ from one another, also can address the above problem.
Certainly, the method for clamping of gripping section also can be as shown in Figure 9, only by one side gripping section 621
1Bending is towards the gripping section 621 of another side
2, and gripping section 621
2Then be to extend upwards bending of a vertical angle, because gripping section 621 from basic segment 611
1Angle of bend have enough yield strengths, therefore only need the gripping section 621 of single side
1Bending can be same reach the clamping effect.
This novel surface is installed second preferred embodiment of open type clipping device, as Figure 10 and shown in Figure 11, in this example, the adsorption section 613 ' of installed part 61 ' is outstanding along the length direction extension of this novel clipping device with basic segment 610 ' opposition side, to be provided as the usefulness of absorption, and get two prominent points respectively inwardly with as gripping section 621 ' by the mode that punching press is sentenced on two gripping section elastic arm 623 ' planes, as shown in Figure 11, gripping section 621 ' extends along the length direction of this novel clipping device respectively, and be formed with a limiting section 622 ' that staggers each other, therefore, no matter be crown cap or wire rod, also can see through such method of clamping and reach identical clamping effect.
A kind of surface mounting upper open formula clipping device that this is novel, because the structural design of bending is simple, it is more or less freely to make making go up, finished product rate or output all can obtain to promote manufacturing cost thereby reduction; And so simple structure not only allows wire rod or crown cap be installed easily, also has more to have better fixed effect, when promoting the installation effectiveness increase, still has the purpose of better fixed effect.
The above only is this novel preferred embodiment, when the scope that can not limit this novel enforcement with this, promptly the simple equivalent of doing according to this novel claims scope and novel description generally changes and modifies, and all should still belong in the scope that this novel patent contains.
