DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power terminal protecting device used in connecting a power line in a compressor having a power terminal portion.

[0002]

2. Description of the Related Art A conventional power supply terminal protection device for a compressor of this type will be described with reference to the drawings. In FIG. 5, a power supply connection portion 12 is provided on an upper portion of a sealed container 11 containing a motorized element and a compression element.
3 , the lead wire covered with the soft vinyl chloride cap 14 was engaged with the power supply connection terminal 15, and the terminal cover 16 was further provided.

Conventionally, as shown in FIG. 6, after a one-touch sleeve 17 is engaged with a faston terminal caulking portion,
It was engaged with the power supply connection terminal.

[0004]

However, in the above-described configuration, a soft vinyl chloride cap must be manually inserted into the lead wire before swaging the Faston terminal of the lead wire, which is labor intensive and operable. Was bad.

In addition, since the material is soft vinyl chloride, if the power supply terminal is heated to 60 ° C. or more, the power supply terminal may be dechlorinated and decomposed, and the terminal may be corroded by metal, which may cause electrical tracking. .

When using a one-touch sleeve,
Engage the one-touch sleeve around the Faston terminal and then engage with the power connection terminal.
In some cases, the engagement portion of the one-touch sleeve itself is disengaged and opened, so that the original purpose of protecting the lead wire is not achieved.

Further, instead of inserting the Faston itself into the power supply connection terminal, the connection terminal may be inserted between the one-touch sleeve and the Faston terminal, resulting in poor electrical connection.

[0008] In addition, during the work of routing the lead wire around the connection terminal portion, the lead wire sometimes jumps up, passes over the connection terminal, and is caught in the terminal cover.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art. The power supply terminal protection device has a shape having a partition wall and an outer wall. Is intended to prevent erroneous insertion into the connection terminal.

It is another object of the present invention to clarify the vertical shape of the protection device and improve the strength of the protection device.

Another object of the present invention is to provide a protection device for a lead wire, and to facilitate the work of winding around an outer peripheral portion.

[0012]

Means for Solving the Problems The present invention to solve the above problems, the main body portion of the power supply terminal protection device, and has a partition wall for isolating a plurality of connecting terminals to each other, the partition wall convex
Therefore, surround the connection terminal and make sure that the lead wire is
The outer wall is formed so as not to touch .

According to the present invention, a top plate for connecting one end of each partition wall to the main body is provided.

Further , according to the present invention, a projection is provided on the outer periphery of the outer wall.
It is formed.

[0015]

According to the present invention, the main body has a partition wall for separating a plurality of connection terminals from each other, and is connected to the partition wall to form an outer wall surrounding the connection terminals. Since a plurality of connection terminals are protected at one time, and a Faston terminal that is not engaged with a soft vinyl chloride cap or a one-touch sleeve is engaged with the connection terminal, erroneous insertion does not occur. In addition, it is a component that can be easily configured.
Connection terminals, and lead wires and connection terminals do not touch
Can be isolated.

In the present invention, since the top plate is provided on the main body, the vertical shape of the main body becomes clear and the strength is improved, so that the main body can be easily attached to the power supply connection portion.

Further, according to the present invention, since the protrusion is formed on the outer periphery of the outer wall of the main body, the lead wire is applied to the protrusion when the lead wire is wound around the outer periphery of the protection device.
It is difficult to come off upward.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a power supply terminal protection device for a compressor according to an embodiment of the present invention.

A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a longitudinal sectional view of a power terminal section of the compressor. Reference numeral 1 denotes a closed container which contains an electric element and a compression element. A power supply terminal unit 2 connected to an electric element is provided at an upper portion of the outer periphery of the closed container 1, and a plurality of connection terminals 3 are formed. Reference numeral 4 denotes a power terminal protection device which is attached to the connection terminal from above. 5 is a terminal cover,
The overload relay 6 is housed and the connection terminal 3 is protected.

FIG. 2 is a cross-sectional view of a power supply terminal of the compressor. Each lead wire 7 is caulked at its tip with a Faston terminal 8 and engaged with the connection terminal 3. Reference numeral 4 denotes a power terminal protection device having a partition wall for separating the connection terminals 3 from each other, and connecting to the partition walls to form an outer wall surrounding the connection terminals.

In the above configuration, the faston terminal 8 is
The connection terminals can be securely inserted into the connection terminals 3 and, furthermore, by attaching the protection device 4, a plurality of connection terminals can be isolated and protected at once.

Next, a second embodiment of the present invention will be described with reference to FIG. In the figure, reference numeral 4a denotes a top plate connecting one end of a partition wall of the main body.

In the above configuration, since the vertical shape of the main body becomes clear and the strength can be improved, the protection device can be easily mounted in the gap between the narrow connection terminals.

Next, a third embodiment of the present invention will be described with reference to FIG. In the figure, reference numeral 4b denotes a projection provided on the outer periphery of the outer peripheral wall of the main body. The protrusion is shown in the figure.
"Brim shape" provided over the entire outer circumference of the outer wall
It may be.

In the above configuration, after the Faston terminal is engaged with the connection terminal and the power supply terminal protection device is attached,
Even when the lead wire is routed around, the lead wire does not easily come off and does not bite into the terminal cover.

The body material is made of heat-resistant 6 nylon,
Ensure heat resistance (60 ° C) or flame retardancy (94V-1)
Good.

As a result, it is possible to prevent heat deterioration, metal corrosion due to generated gas, and further generation of combustion in a place where the temperature is likely to be high, such as a power supply connection part of the compressor.

[0028]

According to the present invention, as is apparent from the above description,
The power supply terminal portion of the compressor has a partition wall that separates a plurality of connection terminals from each other, and is connected to the partition wall, and a power supply terminal protection device that forms an outer wall surrounding the connection terminal leads to lead. This eliminates the need to attach a soft vinyl chloride cap or a one-touch sleeve to the faston terminal of the wire, and prevents incorrect insertion or detachment of the sleeve when connecting to the connection terminal. In addition, it can be easily isolated to multiple connection terminals with a single installation,
Workability can be improved.

Further, by providing the top plate connected to one end of the partition wall of the main body, the vertical shape of the main body becomes clear and the strength is improved, so that even a narrow connection terminal can be easily protected. Equipment can be installed.

In addition, since the protrusion is provided on the outer periphery of the outer wall of the main body, the lead wire does not come off when the lead wire is routed around the outer periphery of the connection terminal, so that the work can be reliably performed.
