Charged side patchhole terminal one body 2a is by jack spring 20a and the terminal board 30a formation one of brace 31 with charged side, the jack spring 20b of ground connection side patchhole terminal one body 2b and ground connection side and terminal board 30b form one, and jack spring 20a, 20b are positioned at the inside that each pin inserts mouth 14.
In addition, charged side socket terminal one body component 2a removes button 5a with 4,4 and one of two snaps respectively, and ground connection side socket terminal one body component 2b removes button 5b with 4,4 and one of two snaps and is housed in each cell of described body 11.At this moment, as can be seen from Figure 7, charged side socket terminal one body component 2a, 2a and ground connection side socket terminal one body component 2b are configured to terminal board 30a, 30b up, and jack spring 20a, 20b are down.As socket in the past, as the configuration direction of charged side jack spring 20a terminal board 30a and ground connection side jack spring 20b terminal board 30b direction (with reference to Figure 31) not simultaneously is set, when assembling, when parts are assembled, get the direction of its setting easily wrong, but in the present embodiment because direction is set is mutual same direction, therefore, during assembling, when assembling parts, each that just is not easy to get wrong socket terminal one body component 2a, 2b is provided with direction.
In addition, the snap 4 is here pushed down the electric wire on the sidewall of terminal board 30a, 30b, when making electric wire and terminal board 30a, 30b be electrically connected, stop extracting of electric wire by edge, two (snaps) are set as described above for terminal board 30a, a 30b towards incline direction.One side connects usefulness usually, and the opposing party uses for sending to connect.Be provided with one for terminal board 30a and remove button 5a, be provided with one for terminal board 30b and remove button 5b, push back a described end margin of snap 4, make electric wire be in the state that to extract.
In addition, to charge with the slotting logical empty 18a of the electric wire that is wired to body 11 back sides of using when the terminal board 30a, and with the earthy electric wire inserting hole 18b that is wired to body 11 back sides of using when the terminal board 30b, be positioned on the basic line of two side directions for the top of body 11, the electric wire of the covering by will peeling off front end is inserted into electric wire inserting hole 18a, 18b is last and carry out the wiring operation, is pressed into respectively in abutting connection with electric wire inserting hole 18a by the front end with screwdriver, the releasing button 19a of 18b, 19b and face contact button 5 and carry out the operation that wiring is removed.Promptly, in the present embodiment, shown in the oblique line part of Fig. 9, L utmost point side terminal T1 around the electric wire inserting hole 18a of one side's side, N utmost point side terminal T2 around the electric wire inserting hole 18a of the opposing party's side, earth terminal T3 around the electric wire inserting hole 18b is located substantially on the straight line for two side directions of body 11 tops.
Pin at described socket A1 inserts on the mouth 14, insert 16A shown in Figure 180, the plug P of three-phase, plug P possesses two charging plug 60a and a ground pin 60b, the pin that charging plug 60a inserts the usefulness of charging inserts mouth 14, and the earthy pin of ground pin 60b insertion inserts mouth 14.
Figure 10 (a) and (b) represent plug P is inserted the state of socket A1, and with routine different in the past, three pin insertion mouths 14 are configured in and cover 12 side on the lower side, therefore, between plug P and the switch B1 very wide interval is arranged, the operating portion 50 that plug P can interferometric switch B1 has improved the operability of switch B1.
And, Figure 11, expression is installed in formation on the opening that is connected the frame D2 that the Wiring equipment that uses uses with other socket A2 (with reference to Figure 12) and switch B2, is bonded on the frame D2 owing to engaging with protruding 15, and socket A2 is installed on the dull and stereotyped frame C1.Frame D2 has the peristome that the surface of Wiring equipment is exposed such size substantially fully and form, and socket A2, switch B2 have wideer amplitude than above-mentioned socket A1, switch B1.At this moment, also shown in Figure 13 (a) and (b), three pin insertion mouths 14 are configured in deflection and cover 12 below, therefore, the interval that broad is arranged between plug P and the switch B2, the operating portion 50 that plug P can interferometric switch B2 has improved the operability of switch B1, owing to form operating portion 50 widelyer, its effect is bigger.
Below, adopt Fig. 1～socket A1, switch B1 shown in Figure 10 to be illustrated, but the socket A2, the switch B2 that adopt Figure 11～shown in Figure 13 are too.
At first, Figure 36 represents the state when the plug P insertion socket A3 in the past, because the grounding leg 60b of plug P plays a part to guide than charging pin 60A length, when inserting, at first inserts pin from grounding leg 60b and inserts mouth 14.But in the past, because earthy pin insertion mouth 14 is positioned at and covers 12 upper end, some skew meetings during insertion contact the switch B1 of the top that is installed in socket A3 mistakenly and cause misoperation, perhaps as shown in figure 37, when only socket A3 being combined to decorative panel D1 ', because the material of decorative panel D1 ' is lower than its case hardness of socket A3, therefore impaired easily, near the open upper end (figure bend part) of decorative panel D1 ' is sustained damage.
In the present embodiment, be positioned at and cover 12 substantial middle place, therefore as shown in figure 14, can not interfere with the switch of above socket A3, installing, even have some to be offset the misoperation that also is not easy to cause switch B1 during insertion because earthy pin inserts mouthfuls 14.And, when insertion plug P,, thereby can more easily insert because the earthy pin of aiming inserts mouth easily.
And usually, mount the socket on the opening of the structure that is arranged at wall etc. and when constructing, as shown in figure 15 at the inboard layout line box 101 of the opening that is arranged at structure 100, in this line box, accommodate socket A1 in 101, to be connected respectively to electric wire inserting hole 18a, the 18b at body 11 back sides by running through electric wires 103 in the conduit 102 above the line box 101, carry out upright distribution downwards.At this moment, the electric wire 103 of construction is reserved very long terminal from line box 101, when carrying out the construction of socket A1, the electric wire bending must be accommodated 101 li in online box later on.But in the past, because the electric wire inserting hole 18a that connects electric wire 103 is positioned at the upper end side at body 11 back sides, and electric wire inserting hole 18b is positioned at the lower end side (with reference to Figure 30) at body 11 back sides, therefore, the bending direction of electric wire 103 is unfixing, and the accommodating property of electric wire in the line box 101 is very poor.
To this, in the present embodiment, electric wire inserting hole 18a, 18b, 18a (T1, T2, the T3) upper end side at body 11 back sides are positioned on the straight line to two side directions substantially, electric wire inserting hole 18a, 18b, 18a (terminal T1, T2, T3) are for the bending direction of electric wire 103 point-blank, therefore, easily it is bent on the same direction, in the online box 101 electric wire 103 is had good accommodating property.
And electric wire inserting hole 18a, 18b can obtain the crooked terminal of longer electric wire 103 than near the situation the central authorities that are in body 11 back sides, shown in Figure 16 (a) and (b), even the relatively shorter situation of the terminal of electric wire 103 also can wiring.In addition, in Figure 15, Figure 16, on dull and stereotyped frame C1 ', decorative panel D1 ', only assembled socket A1.
The back side at body 11, expression projects (※ ※ ※ ...) such as producer, model, specification in mint-mark, in the present embodiment, owing to terminal T1, T2, T3 are positioned at the upper end side at body 11 back sides, can be with expression project (※ ※ ※ ...), concentrate on the lower end side at body 11 back sides and mint-mark compactly, can easily discern, produce unified sense the content of expression.
And, on terminal T1, T2, owing to represent with ' L ' that represent polarity of mint-mark, each literal of ' N ', each mint-mark at this ' L ', ' N ' forms convex form, the more eye-catching effect of expression with polarity, the easier identification of terminal of each polarity can be made, the mis-wired that produces owing to misoperation can be prevented.
Further, as shown in figure 17, between each of terminal T1, the T2 of body 11 the insides, T3, be provided with recess (oblique line portion), by make terminal T1, T2, T3 be convex, make terminal T1, T2, T3 is independent from other terminal, the terminal of each polarity can be easily be familiar with, misoperation and mis-wired can be prevented.
