Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings.
Fig. 1 and 2 schematically show a terminal box 100 according to the prior art, the terminal box 100 being primarily a terminal box for an electric machine. Which is typically located at the rear end cap of the motor, is disposed outside the housing 200 of the motor. In this fig. 1 and 2, a cover for closing the junction box housing 10 is removed in order to better show the structure of the interior of the junction box. As shown in fig. 1, the terminal block 100 includes a terminal block 20. The terminal block 20 is generally provided with a plurality of terminals (six terminals are shown in the present embodiment) for connection of cables. The junction box 100 further includes a junction box housing 10 for protecting the terminal members 20, and the terminal members 20 are surrounded and protected by the case 10. The housing 10 may include a base 14 and a wall 16 extending from the base 14. The connection terminal member 20 protrudes through one of the through hole portions 13 on the bottom 14 of the housing 10. The cable is extended from an outlet hole 30 for the power supply lead and the encoder lead provided in the housing 200 of the motor and connected to the connection terminal member 20. Wherein the through hole portion 13 communicates with the outlet hole 30. Wherein when the bottom 14 of the housing of the terminal block 100 is configured as one bottom wall 15 as shown in the drawing, the through-hole part 13 is configured as one through-hole 13 on the bottom wall 15.
At least one flange hole 11 penetrating the terminal box housing 10 is usually provided in the terminal box housing 10, and a cable for external use is inserted into the terminal box 100 through the flange hole 11 to be connected to the terminal block 20 and thus to electrically connect the motor. The glan head 12 should be used when the user is to use it exactly as specified by the manufacturer. A through hole in the glan head 12 is provided for the cable to pass through and then be connected to the glan head hole 11 for protection against water. In the domestic market, and particularly in the low end market, the actual operator will sometimes not use the glan head 12, but will connect the cable directly through the glan head hole 11. Thus, when water is present in the use environment, for example, when it rains outdoors, the water enters the inside of the terminal box 100 through the glan head hole 11, and further enters the inside of the motor through the through hole portion 13 and the outlet hole 30.
In order to improve the condition, the utility model discloses corresponding improvement has been carried out. Reference is made to fig. 3 and 4, which show an embodiment according to the invention. It can be seen that, in the case where the through hole portion 13 of the bottom portion 14 of the terminal block housing 10 is a through hole 13 that can communicate with the outlet hole 30, a circumferential wall 40 is added around the outlet hole 30. Advantageously, the perimeter wall 40 also surrounds the terminal block 20, providing it with water protection. In this embodiment, the peripheral wall 40 is provided on the bottom wall 15 of the bottom 14 of the terminal box housing 10, i.e., the peripheral wall 40 is also provided around the through hole 13. In order that water entering the interior of the terminal box 100 through the glan-head hole 11 does not pass directly through the through-hole 13 in the bottom 14 and into the interior of the housing 200 of the motor, the height H2 of the peripheral wall 40 is set such that the top of the peripheral wall 40 is higher than the lowest edge 111 of the glan-head hole 11 closest to the bottom 14. That is, the height H2 of the peripheral wall 40 as shown in the drawing is made larger than the distance H1 from the bottom 14 at the lowest edge 111 of the glan head hole 11. Thus, even if water enters the inside of the junction box 100 through the glan head hole 11, the water does not go over the top of the peripheral wall 40. Thus, even if the operator forgets to install the glan head, the peripheral wall 40 prevents water from entering the interior of the housing 200 of the motor in the presence of water. The peripheral wall 40 may be formed integrally with the bottom 14 of the terminal block case 10 or may be formed separately from the bottom 14. When the peripheral wall 40 and the base 14 are two separable and separate components, they may be attached to each other by bonding, welding, or the like. The peripheral wall 40 may be made of an elastic material such as rubber, plastic, etc., or may be made of a metal material.
Fig. 5 shows a terminal block 100 according to another embodiment of the present invention. The difference with the embodiment shown in fig. 3-4 is that the peripheral wall 40 is not provided on the bottom wall 15 of the bottom 14, but directly on the housing 200 of the motor. Similarly, the top of the peripheral wall 40 should be higher than the lowest edge of the glan head hole 11. The peripheral wall 40 may be formed integrally with the housing 200 of the motor, or may be formed separately from the housing 200. While the peripheral wall 40 and the housing 200 may be two separable and separate parts, they may be attached to each other by bonding, welding, or the like. The peripheral wall 40 may be made of an elastic material such as rubber, plastic, etc., or may be made of a metal material.
Fig. 6 shows a terminal block 100 according to another embodiment of the present invention. In this embodiment, the terminal box 100 is more simply provided to be directly connected to the housing 200 of the motor, or the through hole portion 13 on the bottom portion 40 of the terminal box housing 10 is provided as the opening portion 13 which is opened as a whole, so that the wall portion 16 of the terminal box housing 10 is directly connected to the housing 200. Thus, the opening 13 also communicates with the outlet hole 30. The peripheral wall 40 may be provided directly on the housing 200. Similarly, the top of the peripheral wall 40 should be higher than the lowest edge of the glan head hole 11. The peripheral wall 40 may be formed integrally with the housing 200 of the motor, or may be formed separately from the housing 200. While the peripheral wall 40 and the housing 200 may be two separable and separate parts, they may be attached to each other by bonding, welding, or the like. The peripheral wall 40 may be made of an elastic material such as rubber, plastic, etc., or may be made of a metal material.
Although not shown in the drawings, it is contemplated that the junction box 100 of the present invention may be used in other devices requiring a junction box besides a motor. Thus, the housing 200 is also not limited to the housing of a motor, but may be the housing of any device provided with a terminal block.
