Then, illustrate movement of the invention.
By Fig. 3 and the auxiliary contact unit 40 shown in Fig. 4 with thread terminal as the auxiliary with spring terminal
Contact point unit is in use, firstly, as shown in figure 5, terminal converting unit 51A and terminal converting unit 51B are pacified independently of one another
Auxiliary contact portion of terminal 43a, 44a and auxiliary contact portion of terminal 43b, 44b loaded on auxiliary contact unit 40.
Terminal converting unit 51A is being installed on auxiliary contact portion of terminal 43a, 44a and is pacifying terminal converting unit 51B
When loaded on auxiliary contact portion of terminal 43b, 44b, firstly, removed together with washer 49 with auxiliary contact portion of terminal 43a, 44a, 43b,
The terminal screw 46 that the internal thread part 48 of the terminal board 45 of 44b is screwed.In this state, by terminal converting unit 51B's
The portion of terminal 54a for being connected terminal 54 is placed on the terminal board 45 of auxiliary contact portion of terminal 43b, 44b.
At this point, being sticked in the engaging slot 54d formed in the portion of terminal 54a for being connected terminal 54 in the formation of terminal board 45
Ridge 50.Since terminal board 45 is fixed in a manner of non-rotatable by side wall 40a, 40b, as shown in figure 5, terminal is converted
Unit 51B by along with the front up and down direction at right angle of auxiliary contact unit 40 it is extended in a manner of positioned.
In this state, make to be equipped with washer 49 terminal screw 46 pass through the through-hole 54a1 for being connected terminal 54 and with end
The internal thread part 48 of daughter board 45 is screwed and is fastened.
At this point, the front surface in washer 49 is contacted with the head of terminal screw 46, the back side of washer 49 and connected terminal
In the state of the upper surface contact of 54 portion of terminal 54a, during until engaging slot 54d starts to engage with ridge 50
Interior, operating personnel keeps terminal converting unit 51B with hand.Then, the holding to terminal converting unit 51B is released in operating personnel
And when having carried out fastening to terminal screw 46, engaging slot 54d engages with ridge 50, plays positioning and rotation stop these two aspects as a result,
Function, terminal converting unit 51B will not be rotated because of the rotation of terminal screw 46 but accurately be positioned and fixed.Cause
And it can be easy to carry out the installation relative to auxiliary contact portion of terminal 43b, 44b of terminal converting unit 51B in a short time
Operation.
At this point, 50 side view of ridge in the formation of terminal board 45 of auxiliary contact portion of terminal 43b, 44b is formed as semi-circular shape,
Be formed as triangle in the engaging slot 54d side view that the portion of terminal 54a for being connected terminal 54 is formed.Therefore, even if in ridge 50
Cross sectional shape and engaging slot 54d cross sectional shape not accurately in molding situation, can also utilize the engaging of triangle
The centering function of slot 54d accurately carries out positioning and rotation stop.
Then, terminal converting unit 51A is installed on auxiliary contact end according to sequence identical with terminal converting unit 51B
Sub-portion 43a, 44a.At this point, positioning function and rotation stopping function are played using ridge 50 and engaging slot 54d, and can be in a short time
It is easy to carry out installation exercise of the terminal converting unit 51A relative to auxiliary contact portion of terminal 43a, 44a.
Auxiliary contact portion of terminal 43a, 44a of the terminal converting unit 51A relative to auxiliary contact unit 40 is completed as a result,
The installation of installation and terminal converting unit 51B relative to auxiliary contact portion of terminal 43b, 44b of auxiliary contact unit 40.This
When, as shown in figure 5, terminal converting unit 51A, 51B is to be precisely aligned along a flat plane and keep along the extended state of up and down direction.
In this state, auxiliary contact portion of terminal 43a, 43b of auxiliary contact unit 40,44a, 44b, terminal converting unit
The connected terminal 54 and spring terminal 56 of 51A, 51B expose.Therefore, with cover auxiliary contact portion of terminal 43a, 43b, 44a,
