Figure 18 is the perspective view that bonding station is according to the plug power assisting device of the application；Figure 19 is according to the application Plug power assisting device is in the side view of bonding station；Figure 20 is to be in be disengaged position according to the plug power assisting device of the application The perspective view set；Figure 21 is the side view that disengaged position is according to the plug power assisting device of the application；Figure 22 is basis The stereogram exploded view of the plug power assisting device of the application.

Make hook portion 421 and stopper section first when that will plug in the engagement to rack 2 of power assisting device 1 referring to Figure 18-Figure 22 21 abut.Then, plug power assisting device 1 changes the institute into Figure 18 and Figure 19 from disengaged position shown in Figure 20 and Figure 21 The bonding station shown, to make to plug the Male/female connector docking (state shown in Figure 2) in power assisting device 1 and rack 2. In this process, operator causes handle portion towards the handle portion 310 of front (direction in Figure 21 to the left) pressing handle portion 30 30 rotate clockwise (referring to Figure 19 and Figure 21).At this point, linkage attachment portion 331 is equally rotated clockwise, thus the company of drive Bar portion 20 translates up.Link rod part 20 translates up and then the first end 410 of STATEMENT OF FEDERALLY SPONSORED 40 is driven to translate up together.Due to even The second end 420 of bar portion 20 is pivotally secured on STATEMENT OF FEDERALLY SPONSORED connection part 130, and the first end 410 of STATEMENT OF FEDERALLY SPONSORED 40 is flat upwards Shifting causes the second end 420 of STATEMENT OF FEDERALLY SPONSORED 40 to be rotated counterclockwise, and then hook portion 421 is driven to rotate, and eventually leads to plug power-assisted The distance between the main part 10 of device 1 and rack 2 gradually become closely, so that Male/female connector abuts each other.

When plugging power assisting device 1 equipped with latching portion 150, latching portion 150 can be prevented in plug power assisting device 1 close to rack During 2, plug power assisting device 1 moves along the vertical direction relative to rack 2, or even prevents plug power assisting device 1 It is mobile along the vertical direction with left and right directions relative to rack 2.When plug power assisting device 1 is not provided with latching portion 150, male-female coupling Contact pin on device can prevent during plugging power assisting device 1 close to rack 2, plug power assisting device 1 relative to rack 2 along upper Lower direction and left and right directions are mobile.Preferably, plug power assisting device 1 is equipped with latching portion 150.

When being disengaged plug power assisting device 1 with rack 2, whole process is with more than on the contrary, therefore no longer superfluous herein It states.

When handle portion 30 rotates to the state in Figure 19, the clamping part 311 of handle portion 310 is lockable to locked component 50。

Figure 16 is the perspective view according to the pressing piece of the locked component of the plug power assisting device of the application；Figure 17 is according to this The side view of the pressing piece of the locked component of the plug power assisting device of application；Figure 23 is at the plug power assisting device according to the application In the front view of disengaged position, wherein locked component is in unlocked state；Figure 24 is that the line W-W in Fig. 5 is intercepted Cross-sectional view；Figure 25 is the cross-sectional view of the line X-X interception in Figure 23.

Referring to Fig. 5, Figure 16-Figure 17 and Figure 23-Figure 25, locked component 50 can have pressing piece 510 and spring 520.It presses Casting die 510 may include press section 511, wedge-shaped part 512 and guide portion 513.Locked component 50 can be housed in the lock of main part 10 Determine in component holding part 140.In the present embodiment, pressing piece 510 includes two guide portions 513.Guide portion 513 is formed as substantially Cylindricality.Two guide portions 513 are arranged with spring 520 above.Optionally, spring 520, which can be replaced other, can generate elasticity The component of power.Wedge-shaped part 512 may be provided between two guide portions 513, and be exposed to except locked component holding part 140.It presses Splenium 511 may be formed at the top of pressing piece 510.Be respectively formed on wedge-shaped part 512 and clamping part 311 be fitted to each other it is oblique Face.

The clamping part 311 of handle portion 310 is locked to during locked component 50, and the inclined-plane of clamping part 311 abuts wedge-shaped part 512 inclined-plane to make pressing piece 510 overcome the elastic force of spring 520 and move down, thus allow handle portion 310 further to Preceding movement.In the process, when the contact area on the inclined-plane of clamping part 311 and the inclined-plane of wedge-shaped part 512 is gradually reduced and finally When not contacting, since the inclined-plane of clamping part 311 no longer applies downward thrust to pressing piece 510, then pressing piece 510 is due to bullet The restoring force of spring 520 and be moved upwards up to initial position.When pressing piece 510 returns to initial position, the rear side of clamping part 311 (referring to fig. 2 4) are abutted with the front side of the shape of wedge-shaped part 512 part in the slope, thus locked hand portion 310.

When needing to unlock handle portion 310, operator can be pressed down press section 511, so that 510 grams of pressing piece The elastic force for taking spring 520 moves down, until the front side of the shape part in the slope of the rear side and wedge-shaped part 512 of clamping part 311 It no longer abuts, to allow handle portion 310 mobile backward (counter clockwise direction in Figure 24 in other words).

It can be equipped with elasticity part (for example, torsional spring) in handle portion 30, the elasticity part is at least one in two arms 320 A applied force, to tend to make handle portion 30 mobile towards the direction being disengaged with body part 10.That is, due to elastic part The effect of part, when not having power to be applied in handle portion 30, handle portion 30 tends to rotating in an anti-clockwise direction in Figure 24.

In this application, two components further include using fastening cap simultaneously by connections such as connecting rod 610 or fastening nails 640 620 the case where.Connecting rod 610, fastening cap 620, pressing plate 630 and the collectively referenced as fastener 60 of fastening nail 640.In connecting rod 610 Annular knurl line can be formed with.In this application, fastening nail 640 refers to screw or the pin fastener with annular knurl line, etc..At this In application, fastening cap 620 refers to the hat shape fastener, etc. with annular knurl line or screw thread.Connecting rod 610 or fastening nail 640 can Cooperated by way of interference fit with fastening cap 620 or pressing plate 630.If the plug power assisting device 1 of the application optionally includes Dry fastener 60, however each component in plug power assisting device 1 can also be used other modes and be directly connected to, and not necessarily include Fastener 60.Fastening nail 640 can be replaced bolt, pin etc..The both ends of connecting rod 610 can be formed with external screw thread, or connection Whole outer surfaces of bar 610 are formed in screw thread or connecting rod 610 and do not form screw thread.
