Detailed description of the invention
Below in conjunction with Figure of description and concrete preferred embodiment, this utility model is further described, but not because of
This and limit protection domain of the present utility model.
Embodiment:
As shown in Figures 3 and 4, the chopper Mume flower contact erecting device of the present embodiment, including locating shaft 1 with for by Flos Mume
The wedge 2 that the conductive contact finger 31 of contact 3 struts, locating shaft 1 is in axial direction provided with guiding auxiliary section 11, and wedge 2 is sliding
It is located on guiding auxiliary section 11.
When installing Mume flower contact 3, first chopper Mume flower contact erecting device is placed on conductive contact arm 4, wedge 2
Big end and the upper surface of conductive contact arm 4 and to the heart, then by Mume flower contact 3 from the small end set of the wedge 2 of this device
Entering and be pressed downward against, Mume flower contact 3 down slides into holding greatly of wedge 2 along the conical surface of wedge 2, final after departing from this device
Slide in the fixing groove 41 of conductive contact arm 4, when taking frock, first skid off locating shaft 1, further take out wedge 2, i.e. complete Flos Mume and touch
The installation of 3.This apparatus structure is simple, and simple operation is time saving and energy saving, owing to relying on the cooperation of locating shaft and wedge to make prunus mume (sieb.) sieb.et zucc.
Flower contact expansion, need not fiddle with fingertip stage clip；It addition, after having assembled, by first skidding off locating shaft, wedge loses and props up
Support is more easy to take out, and preferably protects conductive contact finger injury-free.I.e. while perfection assembling Mume flower contact, also reach protection
The purpose that the parts such as conductive contact finger and fingertip stage clip are injury-free, reduces the damage risk of chopper Mume flower contact.
As preferred embodiment, it is also possible to arrange multiple wedge 2 further, multiple wedges 2 are uniformly distributed in leads
Outer surface to auxiliary section 11.The advantage one so arranged is to ensure that Mume flower contact 3 is being inserted in this device the mistake being pressed downward against
Uniform force in journey；Two is after Mume flower contact 3 slides into the fixing groove 41 of conductive contact arm 4, can directly upwards be pulled out by locating shaft 1
Out, after multiple wedges 2 lose support naturally, reduced diameter directly can be taken out from Mume flower contact.Both guaranteed that Flos Mume touched
3 in whole installation process conductive contact finger and fingertip mounting bracket injury-free, also ensure that assembling can safe and convenient after completing
This device of taking-up.In the present embodiment, wedge 2 is provided with three.
In the present embodiment, wedge 2 is taper seat with the contact surface of conductive contact finger 31, the axis of this taper seat and locating shaft
The dead in line of 1.Can reduce frictional force suffered during conductive contact finger 31 is pressed downward against, protection conductive contact finger is not further
Damaged.
In the present embodiment, the outer diameter D 1 of wedge 2 miner diameter end is less than the internal diameter d of the snap ring 311 of Mume flower contact 3, wedge 2
The outer diameter D 2 of bigger diameter end is more than or equal to the end face diameter D of conductive contact arm 4.The end face diameter of conductive contact arm 4 refers to conduction and touches
The end face diameter of one end that arm 4 assembles with Mume flower contact 3.
In the present embodiment, the outer surface guiding auxiliary section 11 is provided with draw-in groove 111, and wedge 2 is slidedly arranged in draw-in groove 111.
In the present embodiment, wedge 2 is provided with the Access Division 21 corresponding with draw-in groove 111, and draw-in groove 111 can be trapezoidal key
Groove, it is ensured that locating shaft 1 closely cooperates with wedge 2.
In the present embodiment, on locating shaft 1, the one end near wedge 2 bigger diameter end is provided with for the arm aperture with conductive contact arm 4
The location division 12 of socket.Both having facilitated the location of this device and conductive contact arm 4, during also ensureing assembling, this device does not rocks.
In the present embodiment, locating shaft 1 is provided with near one end of wedge 2 miner diameter end pulling part 13, convenient for assembly completes
