Embodiment

Hereinafter, describe the AC socket according to an enforcement mode, supply lead with reference to the accompanying drawings in detail and there is their display unit.

As depicted in figs. 1 and 2, the display unit 1 being set to show image comprises: display panel 200 (with reference to Figure 12), displays image information; Bonnet 1a, protection display panel 200 and internal electronic element, from the externalities of display panel 200.

Bonnet 1a can be set to be formed the outside of the rear surface of display unit 1. An enforcement mode describes the example that bonnet 1a is formed as anterior border and the rear surface covering display unit 1 overallly. But, the spirit implementing mode is not limited to this. Such as, bonnet 1a can independently be formed as can with the four of display unit 1 edge separation.

Bonnet 1a forms the rear surface of display panel, and for the protection of display unit 1, from the impact of external impact, dust, moisture etc.

Supply lead 10 for powering is arranged at display unit 1 place. Supply lead 10 can be arranged to removably be connected to display unit.

Display unit 1 is supported by support 3. Support 3 can comprise the connection section 4 that the rear surface with bonnet 1a is connected.

Meanwhile, installation portion 2 is arranged on the rear surface place of the bonnet 1a of display unit 1, and supply lead 10 is connected to installation portion 2. Installation portion 2 can comprise hole 2a, and hole 2a is formed through installation portion 2 so that the socket (not shown) being connected to the junctor 20 of supply lead 10 is exposed to the outside of bonnet 1a.

Enforcement mode has described the example that installation portion 2 is formed through the bonnet 1a of display unit 1. But, the spirit implementing mode is not limited to this. Such as, installation portion 2 can be formed as being recessed into from bonnet 1a with predetermined depth.

Supply lead 10 for powering to display unit 1 comprises cable 11, is connected to the plug 13 of one end of cable 11 and is connected to the junctor 20 of the other end of cable 11.

Cable 11 is formed by coated many wire 11a and 11b, and electric current flows through described many wire 11a and 11b.

Plug 13 is connected to one end of cable 11. Plug 13 is arranged through outlet (not shown) and is connected with outside power supply, and therefore connects or breaking circuits.

Junctor 20 is connected to the other end of cable 11. Junctor 20 can be arranged to be coupled to the installation portion 2 of display unit 1.

Fig. 3 A is the skeleton view of the junctor illustrating the supply lead implementing mode according to, Fig. 3 B is the view in the cross section illustrating the cable implementing mode according to, Fig. 4 is the side-view of the junctor illustrating the supply lead implementing mode according to, and Fig. 5 is the front view of the junctor illustrating the supply lead implementing mode according to.

As shown in Fig. 3 A to Fig. 5, the junctor 20 of supply lead 10 comprises: cable connecting part 24, and cable 11 inserts in cable connecting part 24; Head 21, is connected with cable connecting part 24; And connect portion of terminal 27, it is connected with head 21.

Junctor 20 comprises: cable connecting part 24, is formed along first party to A, and cable 11 inserts and is connected to cable connecting part 24; Head 21, is connected to cable connecting part 24 and is formed to the second direction B that A is vertical along with first party; And connect portion of terminal 27, it is connected with head 21, it is set in insertion installation portion 2 and is formed to the third direction C of A and second direction B along being different from first party.

Junctor 20 can according to connecting portion of terminal 27, head 21 and be formed as the order of cable connecting part 24 bent from head 21 downwards and the shape being formed as having approximate " L ".

The head 21 of junctor 20 has oval appearance, its front surface opened, and connects portion of terminal 27 and be arranged on front surface opening 21a place. Cable connecting part 24 is arranged on the lower surface place of head 21. Enforcement mode has described the example of junctor 20, this junctor 20 has cylindrical shape, and its front surface opened and rear surface are closed, and upper surface and lower surface are smooth, surface, two sides is formed as semicircular in shape, and cable connecting part 24 passes and is connected to its lower surface. But, the spirit implementing mode is not limited to this. Such as, the head of junctor can have the shape of rectangle or square, and two surface, side is all smooth.

Cable connecting part 24 is formed as making to communicate with head 21 and passes the cable 11 that cable connecting part 24 inserts and be connected internally to, by head 21, connection terminal 27a and 27b being connected portion of terminal 27.

Cable connecting part 24 is arranged so that wire 11a and 11b is connected with head 21 through the lower surface of head 21 and passes head 21. The example at the lower surface place that cable connecting part 24 is integrally formed in head 21 has been used to describe enforcement mode. But, cable connecting part 24 and head 21 can be formed as separable each other.

Cable connecting part 24 is formed as hollow pipe shape, and its one end is connected to head 21, and the other end open wide lead line pluging handhole 24a to have, wire 11a and 11b insert lead in line pluging handhole 24a.

The outer surface that groove 25 is arranged on cable connecting part 24 sentences the flexibility improving cable connecting part 24. Groove 25 is formed as circumferentially having predetermined length. At least one or more groove 25 can be provided, or multiple groove 25 can be provided.
