The three plug pins are divided into a pin for supplying power to the driving motor which operates the rotary [R:\LIBLLI 17529.doc: KEH brush 23, a pin for supplying power to the light 25, and a ground pin. As shown in FIG O the plug pin 113 is formed stepwise in the diameter in a manner that a first portion 113a O mounted in the pin housing 114 has a larger diameter than a second portion 113b projected to the outside of the pin housing 114.
The pin housing 114 is made of a nonconductor and comprises a connection groove 114a, a via-hole 114b formed in the connection groove 114a, and a support part N 114c. Being respectively received in the connection grooves 114a, the plug pins 113 are Sinsulated from one another. The plug pin 113 being inserted in the connection groove 114a is passed through the via-hole 114b and exposed to the outside of the plug 112 by 1o one end thereof. The support part 114c supports a stepped portion 113c defined by the first and second portions 113a, 113b of the plug pin 113 so as to prevent escape of the plug pin 113 from the plug 112 through the via-hole 114b.

The plug supporter 115 fixes the plug pins 113 being seated on the connection grooves 114a and comprises plug pin supporting projections l15a formed to correspond to the plug pins 113 and fit into the connection grooves 114a.
Since the plug pins 113 inserted in the connection grooves 114a are fixed between the support parts 114c and the plug pin supporting projections 115a, the plug pins 113 do not move during separation and connection of the plug 112. Accordingly, no load is applied to a connection point between the electric wire W1 and the plug pin 113 when connecting and separating the plug 112. After assembling sequentially the plug pins 113, the pin housings 114 and the plug supporters 115, the exterior of the assembly is overmolded so that the plug pins 113 and the electric wires W are more stably fixed.
Accordingly, disconnection and short-circuit can be prevented.
As shown in FIGS. 4 and 6, the second cable unit 120 comprises a second terminal 121, an outlet 122 and an electric wire W2. As shown in FIG 3, the second cable unit 120 is mounted in the second socket 31 formed in the cleaner body The second terminal 121 is connected with the power supply unit (not shown) formed in the cleaner body 30 to supply the power to the second cable unit 120.

The pin socket 123 is formed as a pipe having an inner diameter corresponding to a diameter of the second portion 113b of plug pin 113 so as to receive the plug pin 113 Stherein. Also, the pin socket 123 is in connection with the electric wire W2 to be supplied with power.
SThe pin socket housing 124 supports the respective pin sockets 123 and N, determines locations for mounting the pin sockets 123. For this, the respective pin 1o sockets 123 are engaged with seating grooves 124a formed at the pin socket housing 124.
The outlet cover 125 comprises hollow depressions 125a for respectively receiving the pin sockets 123 being engaged with the pin socket housing 124, thereby insulating the pin sockets 123 from one another. As shown in FIG 6, one end 127 of the hollow depression 125a, in which the electric wire W2 is inserted, has a smaller diameter is than an outer diameter of the pin socket 123 so that the pin sockets 123 are more stably fixed.
As described above, in the second cable unit 120, when the pin sockets 123 connected with the electric wire W2 are fixed between the pin socket housing 124 and the outlet cover 125, the pin sockets 123 do not move even during separation and mounting of the plug pins 113 with respect to the pin sockets 123. Therefore, no load is applied to a connection point between the pin socket 123 and the electric wire W2 when mounting and separating the plug pins 113. After assembling sequentially the pin sockets 123, the pin socket housing 124 and the outlet cover 125, the exterior of the assembly is overmolded so that the plug pins 113 and the electric wires W are more stably fixed. Accordingly, disconnection and short-circuit can be prevented.
