BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring connection device for an electrical component of an indoor unit of an air conditioner.

0002

BACKGROUND OF THE INVENTION In recent years, the prevalence of air conditioners has increased, and from one unit per household to one indoor unit per room.

[0003] Furthermore, since the mainstream air conditioners are of a separate type, the indoor unit installed indoors and the outdoor unit installed outdoors are connected by insulated piping during the refrigeration cycle. On the other hand, the electrical wiring is connected by a VVF consisting of a flat two-core vinyl insulated vinyl sheathed cable.

Conventionally, the V of the electrical component of such an indoor unit
The VF connection section had a configuration as shown in FIGS. 4 and 5. That is, the electrical equipment box 101 of the indoor unit is molded with resin, and the terminal block 103 that enables connection of the VVF 102 from the outdoor unit and the electrical equipment part (whole not shown) of the indoor unit is connected to the electrical equipment with screws 104. box 101
is fixed. On one side of the terminal block 103 is a lead wire 1 that connects to the electrical equipment section of the indoor unit (the whole is not shown).
Faston terminal 106 processed on one end of 05 is tab 1
It is fitted in 07. The other side has a structure in which the single copper wire of the uncovered portion of the VVF 102 cannot be easily removed once it is inserted.

FIG. 5 is a cross-sectional view of a part of the electrical box 101 (the terminal block is not shown), and there is a fixing plate for fixing the VVF 102 so that the VVF 102 does not easily come off the terminal block 103. 108 was fixed at one end by a hook and at the other end by a fixing screw 109.

[0006]

[Problems to be Solved by the Invention] In the configuration of such a conventional wiring connection device, when connecting the VVF 102 and the terminal block 103 in the electrical box 101, the coating at the tip of the VVF 102 is peeled off and the exposed single copper wire is removed. Before inserting the VVF into the terminal block 103, fix the fixing plate 10 to prevent the VVF 102 from coming off easily.
8 fixing screws 109 must be removed using a tool, and the fixing plate 108 must also be removed at the same time.
102 into the terminal block 103, hook one end of the fixing plate 108 onto a part of the electrical box 101, hold the VVF 102 with the fixing plate 108, and use a tool to fix the other end with the fixing screw 109. , it is necessary to use tools, and when the fixing screws 109 are removed, the fixing plate 108 also comes off, so there is a risk of dropping the fixing screws 109 or the fixing plate 108 when removing or installing. There was a problem that it was troublesome during construction.

[0007] The present invention solves these problems and aims to provide a wiring connection device for the electrical component of an indoor unit that enables connection of a VVF to the electrical component of the indoor unit without using tools. The purpose is

[0008]

[Means for Solving the Problems] In order to achieve the above object, the present invention has a terminal block in a part of an electrical box, and a VVF fixing part is provided below the terminal block integrally with the terminal block. VV
The F fixing part is provided with a floating holding part on the upper part of one side, and a wedge surface on the other side that slopes upward and in the direction of spreading, and on this wedge surface, there are a number of acute angles. A groove is formed, and the VVF is fixed so as to be sandwiched between the grooves on the lower surface.

[0009]

[Operation] With the above-described configuration, the present invention has a VVF on the terminal block.
When connecting, pass the VVF through the wide part above the VVF fixing part, and after inserting it into the terminal block, manually insert the VVF into the underside of the wedge-shaped wedge surface, making sure it is in close contact with the wedge surface, and aligning it with the insertion direction. When pulled in the opposite direction, the VVF bites into the narrow direction of the wedge surface and tightens the VVF, so the VVF does not come out and the VVF can be removed without using tools.
F can be connected to facilitate construction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

As shown in the figure, a terminal block 3 is provided on a part of the electrical equipment box 1 molded of resin together with the indoor unit to connect the VVF 2 wired from the outdoor unit to an electrical equipment part (not shown). are fixed with screws 4. A wedge shape is formed on the central axis of the terminal block 3 in the insertion direction at a slight distance below the insertion surface 5 of the VVF 2 of the terminal block 3, facing toward the terminal block 3 and opening upward. In order to increase frictional resistance, a large number of acute-angled grooves 8 are formed on the wedge surfaces 7a and 7b, and an opening 9 through which the VVF 2 can pass is formed in the opposite direction to the terminal block 3. A VVF fixing section 10 consisting of the above-mentioned electrical equipment box 1 is provided.

FIG. 3 is a cross-sectional view taken along line A-B in FIG. The VVF 2 is easily inserted by forming a slope that widens toward the front. Therefore, the VVF increases toward the bottom.
The space through which the VVF 2 passes is narrower at the bottom so that it can be easily tightened by sandwiching the VVF 2.

[0013] Further, in the lower part of the VVF fixing part 10, a VV
The VF2 is provided with a floating holding part 11 toward the top, and the VF2 is
This is to prevent VF2 from rising too high.

In the above configuration, when connecting the VVF2 to the terminal block 3 of the indoor unit, the VVF2 is connected to the VVF fixing part 1.
Since the upper part of 0 has a wide area, the opening 9 is passed through that part. That is, the single copper wire from which the coating of the VVF 2 has been stripped is inserted into the terminal block 3 through the upper part of the wedge shape.

Thereafter, the VVF 2 is forcibly pushed downward by hand so that the VVF 2 is brought into close contact with the electrical equipment box 1, and the VVF 2 is securely fixed by sandwiching the VVF 2. Therefore, even if there is an accident where the outdoor unit is pulled due to a strong impact from the VVF fixing part 10, the VVF 2 will be pulled in the opposite direction to the terminal block 3, and the grooves 8 on the wedge surfaces 7a and 7b will VVF2 is tightened even more,
The VVF2 is fixed and is held in place more strongly against impact.

[0016] Therefore, the VVF 2 can be fixed very simply and a robust fixing device can be obtained.

[0017]

As is clear from the description of the above embodiments, the present invention provides a VVF fixing part below the terminal block as a device for inserting the VVF into the terminal block when connecting the VVF to the terminal block. The fixing part has a groove with one side inclined upwards and a wedge surface in the direction of insertion and removal of the VVF, so the VVF can be easily inserted and the groove can be easily inserted after being inserted into the terminal block. Press the VVF with your hands so that it is in close contact with the wedge surface.
If you pull it from the VF fixing part side in the opposite direction to the insertion direction, it will bite into the wedge surface further and tighten the VVF, so the VVF will not come out.

[0018] Furthermore, since the floating holding part is integrated with the VVF fixing part, it does not come off or come off upwards, resulting in high safety.

Furthermore, the air conditioner has the advantage of being able to connect the VVF without using any tools, and since no parts are removed during connection, there is no need to worry about dropping parts, and the air conditioner can be easily installed. Wiring connection device can be provided.
