AI Technical Summary

Problems solved by technology

[0004] However, sometimes the charging member and the metal member of the non-charging member are arranged relatively close to each other, so that a sufficient insulating distance cannot be ensured between the non-charging member such as the assembly frame and the charging member.
And because the assembly of the body requires the use of assembly frames and screws, the assembly work is cumbersome
In addition, the usual socket has only one installation position for the bottom plate, so different products are required due to the difference in the number of insertion parts.

Embodiment 3

[0108] Example 3 is as Figure 13 As shown, only one engaging hole 22a is provided on the assembling piece 22 , and a reinforcing piece 22c is extended forward from the rear edge of the assembling piece 22 . The rear end portion of the assembly claw 11 provided on the main body portion 10 is formed in a bifurcated shape, and is engaged with the reinforcing piece 22c. In this configuration, the thicker reinforcing portion 22b is also formed on the reinforcing piece 22c, thereby reliably preventing the assembly piece 22 from being split due to the formation of the weld line. Other structures and functions are the same as in Embodiment 1.

[0109] In the above-mentioned embodiment, the assembling claws 11 are protruded from the upper and lower sides of the main body 10, such as Figure 14 and 15 As shown, in the fourth embodiment, a pair of assembly claws 11 are protrudingly provided on the left and right sides of the main body 10 . That is, notches 17 are formed on the outer...

Embodiment 5

[0116] Embodiment 5 is to form two engaging holes 22a in the assembly piece 22, and in this embodiment 6, then as Figure 18 and Figure 19 As shown, only one engaging hole 22 a is provided in the assembly piece 22 . Therefore, only one assembly claw 11 is provided on the main body portion 10 . Other structures and functions are the same as those in Embodiment 5.

Embodiment 7

[0117] Example 7 is as Figure 20 As shown, there are two insertion parts 24 having the same structure as that of the fifth embodiment. Therefore, the body 1 adopts three unit sizes.

[0118] Inside the body part 10, three storage chambers 13a-13c are formed by the partition wall 12, and the contraction chamber 13c which accommodates the bolt blade receiving part 60 of the ground electrode is elongated along the longitudinal direction of the body 1, and the middle part A constricted portion 13d is formed. The other two storage chambers 13a, 13b respectively accommodate the bolt blade holders 50, and the partition wall 12b having the slit 12a is formed at two places in the middle to divide the storage chamber 13 into three.

Abstract

A power outlet can be assembled easily. The main body 1 of a power outlet is held by a plate in such an arrangement that the front end is inserted in a rectangular opening formed in the plate to be fixed to working surface. The tail is embedded in the working surface. Pawls 2, which is coupled with retaining grooves provided in the plate at a certain unit pitch, is protruded from the side face of the main body 1. The main body 1 is composed of a body 10 at the tail and a cover 20 at the front end furnished with an insertion part 24 to be inserted with plug blades. The body 10 is coupled with the cover 20 by engaging an assembly pawl 11 on the body 10 with an assembly hole 22a provided in the cover 20.

Description

【Technical field】 [0001] The present invention relates to a receptacle constructed with a part embedded in a construction surface such as a wall surface. 【Background technique】 [0002] Generally, when manufacturing the socket, since a charging member such as a blade holder for receiving the blade is accommodated in the body, two or more members are combined to form the body. The widely used method of combining the components constituting the body is to use a metal assembly frame and metal screws. [0003] Chinese invention patent application CN1101460A discloses a socket, which includes a pin insertion part arranged in the socket shell for inserting and contacting a round plug and a flat plug for inserting and contacting, and a quick-connect joint for connecting external wires. The blade of the plug, and the terminal block portion of the quick-connect connector are supported by a locking spring that applies spring force to the inserted wire.
