Figure 16 is the sectional perspective view of the button wall portion of holding unit shown in Figure 14.

See also shown in Figure 2ly, be the three-dimensional exploded view of the utility model holding unit first embodiment.The utility model holding unit comprises accommodates frame 1, pivoted arm 2 and clava 3, the aforementioned frame 1 of accommodating is formed by plastic material one ejection formation, it comprises the two side, be the first side wall 10 and second sidewall 12, one end of this two sidewall has flexual arc connecting portion 14 by one and links together, and the first side wall 10 is then to offer a shaft hole 16 relatively on connecting portion 14 1 ends.

In addition, pivoted arm 2 is one to have elasticity and roughly be Z-shaped plate body, and the one end is deflected outwardly into operating portion 20, and the other end then is provided with the holding parts 22 of fixing clava 3, then be provided with a pintle hook lock post 24 near medium position, and the head of this pintle hook lock post 24 has an inclined guide face 240.Wherein holding parts 22 is the little keyway 224 at wall thickness of a degree of depth that is arranged with at holding hole 220 lower edge walls that reaches that comprises holding hole 220.

Clava 3 includes integrally formed shaft 30 and button wall portion 32, shaft 30 is cylindrical, it can pass shaft hole 16 and holding hole 220, and can in holding hole 220, freely rotate, and button wall portion 32 can detain the edge of holding with second sidewall 12, and clava 3 middle parts also are integrally formed with a key body 34 that can match with aforementioned keyway 224.

During assembling, the shaft 30 of clava 3 passes the holding hole 220 that is located on the pivoted arm 2 and is located at the shaft hole 16 of accommodating on the frame 1, and then block is in keyway 224 for key body 34, and it as shown in Figure 3.Then, adopt melt process that the head of rotating shaft 30 is shaped to block cap 36, it as shown in Figure 4.At this moment, promptly fitting together and become electric connector holding unit of the present utility model accommodating frame 1, pivoted arm 2 and clava 3, so shaft 30 and button wall portion 32 will be fixed on holding parts 22, and be that fulcrum is along with pivoted arm 2 rotations with shaft hole 16.

When using holding unit of the present utility model, pivoted arm 2 is rotated to as shown in Figure 5 upright position, make the button wall portion 32 of clava 3 break away from the edge 120 of second sidewall 12, thereby the first side wall 10 and second sidewall 12 can be parted a little open, to accommodate frame 1 again and be enclosed within bayonet connector 4 peripheries that are installed on the printed circuit board (PCB) 5, compress two side 10 and 12 then, again pivoted arm 2 is threaded to horizontal level as shown in Figure 6, make the button wall portion 32 of clava 3 detain the edge 120 of holding second sidewall 12, promptly be fixed on bayonet connector 4 outer walls accommodating frame 1, thus with the utility model holding unit group on bayonet connector.

See also shown in Figure 7, the lower edge place of keeping to the side that is plugged on electronics expansion board 6 offers a holding hole 60, and when inserting bayonet connector 4, its lower edge is to contact with the guiding face 240 of the utility model pintle hook lock post 24, and borrow brute force that pintle hook lock post 24 is oppressed to a side, when expansion board 6 is inserted to the slot bottom, thereby pintle hook lock post 24 promptly snaps in holding hole 60 with expansion board 6 lockings.

Then if when needing on connector, withdraw from expansion board 6, can force pivoted arm 2 that certain elastic deformation take place with the operating portion 20 of pivoted arm 2 to external pressure, so that pintle hook lock post 24 detaches holding hole 60, expansion board 6 easily can be drawn off afterwards.

See also Fig. 8 and shown in Figure 9, it is second embodiment of the present utility model, the difference of itself and aforementioned first embodiment is, shaft 30 and button wall portion 32 are formed in one on pivoted arm 2, and the axial line of shaft 30 and button wall portion 32 is not on same straight line, when being the pivoted arm action, button wall portion 32 can rotate around shaft 30, and second wall 12 then offers guide channel 35 in the rotary motion trace of portion 32 relatively.

See also Figure 10 to shown in Figure 13, it is the 3rd embodiment of the present utility model, the configuration of its pivoted arm is different with the design that roughly is the Z-shaped plate shape of two examples in front, it is by oblique two crossing dull and stereotyped compositions, wherein a flat board is an operating portion 20, and another dull and stereotyped two ends then are respectively equipped with as the holding parts 22 of first embodiment and pintle hook lock post 24.In addition, see also shown in Figure 13, the shape and first embodiment of the button wall portion 32 of the clava 3 of present embodiment are different, and the button wall portion 32 of clava 3 is provided with one can limit the stop section 320 of the extreme position that pivoted arm 2 rotates and the holding part 322 that button is held second sidewall.When pivoted arm turns to as shown in figure 10 the upright position, the edge 120 of stop section 320 lucky block second sidewalls, and the axial line of pintle hook lock portion 24 just in time is in the top of clava 3 axial lines, can detain reliably like this and stop the fixing expansion board 6 (with reference to Fig. 7) of this holding unit.

See also Figure 14 to shown in Figure 16, it is the 4th embodiment of the present utility model, the difference of itself and aforementioned the 3rd embodiment is: shaft 30 and button wall portion 32 are formed in one with pivoted arm 2 and form, and the axial line of shaft 30 and button wall portion 32 is not on same straight line, when being the pivoted arm action, button wall portion 32 can rotate around shaft 30.The concrete shape of button wall portion 32 is asked for an interview shown in Figure 16, and it is similar to stop section 320 and the holding part 322 of the 3rd embodiment.
