The essentially rectangular shape respectively surround sheet 241c be formed at each contact chip 241a base end part the left and right side place and to downward-extension.
The a pair of pin that the pin that plug connector 270 comprises substrate 271, be used for flat pins props up relying part 215 and is used for the circle pin props up relying part 216, substrate 271 has the through hole 271a that is limited in its substantial middle zone, pin props up relying part 215 and extends forward from the lower end of substrate 271, and pin props up relying part 216 and extends forward from the left and right end of substrate 271.
Make each locking spring 25 form the roughly shape of C shape by the flexible conductive plate of curved bel (for example, metallic plate).Each locking spring 25 comprises: central plate 251, also cross over the one section space that is used for inserting electric wire 30 towards contact chip 241a; Locking plate 252 extends upward from the rear end of central plate 251; And the butt sheet 253 of L shape roughly, extend upward from the front end of central plate 251.
Although in the present embodiment, the curved tabs 253b of each locking spring 25 all with the corresponding upper surface overlaid of contact chip 241a, the present invention is not limited thereto.Just need outside curved tabs 253b is exposed to by among the 107c of voltage detecting hole at least one.In other words, outside the curved tabs 253b of the part of end bracket 24 and each locking spring 25 can be exposed to by corresponding voltage detecting hole 107c.
The lower surface of curved tabs 253b contacts with the upper surface of corresponding contact chip 241a.The upper surface of curved tabs 253b is exposed to outer (see figure 3) by the corresponding voltage detecting hole 107c of main body 107.
The connecting portion 254 of central plate 251 and locking plate 252 is bent to the roughly shape of semi arch.If the power of a forward action is applied to locking plate 252, so crooked connecting portion 254 diameters reduce in order to make the locking plate 252 can crooked (or displacement).Butt sheet 253 passes one of otch 24a in the left and right edge of the brace 243 that is limited at end bracket 24 and extends forward, and around substrate 241 and then extend back.When end bracket 24 is maintained in one of the locker room 104 of main body 107, because passing corresponding otch 24a, extends stage portion 253c, the part that is positioned at stage portion 253c below of butt sheet 253 is by substrate 242 (see figure 4) that supports of end bracket 24.
As shown in Figure 4, in one of locker room 104 that is disposed in main body 107 such as end bracket 24 and the locking spring 25 of above-mentioned structure.If electric wire 30 passes one of plug wire hole 107b and is inserted into from the outside in one of locker room 104 (as illustrated in Fig. 7), then locking plate 252 is promoted by the top end of electric wire 30 and is downward away from corresponding contact chip 241a() bending.Therefore, electric wire 30 further inwardly inserts.In case electric wire is inserted into assigned address, the top end of locking plate 252 just contacts with electric wire 30, thereby prevents that electric wire 30 (backward) on the anti-plug Inbound is removed.By the restoring force (spring force) of locking spring 25, electric wire 30 is brought into contact surface (lower surface) Elastic Contact with contact chip 241a.This makes it possible to provide electrical connection between electric wire 30 and contact chip 241a.
In the termination unit 40 of present embodiment, if electric wire 30 touches locking plate 252 during connecting electric wire 30, locking plate 252 will utilize connecting portion 254 as fulcrum and away from contact chip 241a(namely so, on the clockwise direction in Fig. 7) mobile.Therefore, the possibility that does not exist locking plate 252 to be blocked by electric wire 30.This makes it possible to improve the reliability of the contact between electric wire 30 and the end bracket 24.
Each contact chip 241a is provided with a pair of encirclement sheet 241c.Therefore, if electric wire 30 is solid conductors, surround the transverse shifting scope that sheet 241c can limit electric wire 30.Be in the situation of twisted wire at electric wire 30, surround the degree of untiing that sheet 241c can limit each strand of twisted wire.This provides an advantage, and namely the reliability of the contact between electric wire 30 and the end bracket 24 further strengthens.In the present embodiment, this is configured as towards corresponding encirclement sheet 241b outstanding to the tip end portion of surrounding sheet 241c.This makes it possible to limit reliably the moving range of electric wire 30 or unties degree.In addition, encirclement sheet 241b being set in end bracket 24 makes it possible to stop electric wire 30 to move away from each contact chip 241a.
In the termination unit 40 of present embodiment, the contact chip 241a of end bracket 24 (that is, on above-below direction) on contact chip 241a and direction that electric wire 30 contacts is flexible.Therefore, even when electric wire 30 tilts with respect to corresponding plug wire hole 107b, contact chip 241a also can make itself adapt to the movement of electric wire 30.This makes it possible to guarantee at any time stable contact.In addition, even the electric wire 30 that is comprised of twisted wire is untied or even electric wire 30 is formed by the wire of minor diameter (carefully), contact chip 241a and locking plate 252 also can flexibly clamp electric wire 30, thus the contact condition between stabilized end fishplate bar 24 and the locking spring 25.Because the degree of crook of contact chip 241a is subject to the inner wall surface of the locker room 104 of main body 107, so even when electric wire 30 tilts, can prevent that also contact chip 241a from standing plastic deformation.
Next, with the description that provides about each release lever 26.Release lever 26 forms and forms as a whole the roughly shape of C shape by synthetic resin is molded.Release lever 26 comprise a pair of semicircle dish type support portion 261, rectangular plate shape operating portion 262 and be used for making respectively support portion 261 and the tabular connecting portion 263 of operating portion 262 interconnected a pair of essentially rectangulars.
In order to remove the electric wire 30 that is connected to termination unit 40, finger can be inserted in each voltage detecting hole 107c, and the operating portion 262(that the drawing that then can make progress is exposed towards the upper surface of main body 107 as shown in Figure 7).More specifically, if operating portion 262 in each voltage detecting hole 107c by upwards drawing, then each release lever 26 all 261 clockwise rotates around the support portion.The upper apex of pushing section 264 begins to make the tip end portion of contact chip 241a to make progress away from electric wire 30() displacement.If each release lever 26 further clockwise rotates, pushing section 264 downward pressing lock stators 252 then, thus the locking plate 252 that keeps contacting with electric wire 30 is moved away from electric wire 30.Therefore, electric wire 30 can remove from termination unit 40.
As the electrical power wiring assembly of the present embodiment of above-mentioned structure in, the curved tabs 253b of each in the termination unit 40(locking spring 25) by main body 107 upper surface portion be exposed to outside.As indicated above, end bracket 24 and locking spring 25 are made by electric conducting material.Therefore, by the voltage detecting pen being inserted in the 107c of voltage detecting hole and the voltage detecting pen being contacted with each curved tabs 253b, can carry out the voltage detecting operation to end bracket 24 via each that locks in the spring 25.
Electrical power wiring assembly with present embodiment can easily carry out wire connection work and voltage detecting operation.
Because each voltage detecting hole 107c is as one section space, the part of the connecting portion 263 of each release lever 26 can move by described space, need not to be provided in addition the space that connecting portion 263 moves.This helps to simplify the structure of electrical power wiring assembly.
In addition, each contact chip 241a of each locking curved tabs 253b of spring 25 and end bracket 24 is arranged to that (on above-below direction) overlaps each other on the perforation direction of each voltage detecting hole 107c, and this can improve termination unit 40 and the intensity contacted part of voltage detecting pen.
Because the curved tabs 253b of each locking spring 25 is arranged to compare with each contact chip 241a of end bracket 24 this fact of more close each voltage detecting hole 107c, does not have the straight possibility that meets each contact chip 241a of contact jaw fishplate bar 24 of voltage detecting.This makes it possible to prevent that end bracket 24 is damaged.
