Description

[Technical Field]

[0001] The present invention relates to a lead wire insertion gasket, a connector fixing structure, and a motor with a connector, and more particularly to a waterproof structure for an adapter used when connecting a motor connector. [Background technology]

[0002] The applicant previously disclosed an invention for an adapter for fixing a motor connector and a waterproof cylindrical gasket (Patent Document 1, listed below). This is a connector fixing structure that improves workability when soldering connector terminals and prevents excess lead wires from coming into contact with internal rotating bodies during subsequent connector installation and resulting defects, thereby improving quality, improving workability, and reducing labor hours. It is an assembled adapter consisting of multiple components that is assembled laterally to the connector to which the lead wires from the motor are connected. The lead wires are protected by passing them through the waterproof cylindrical gasket. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6868243 "Connector fixing structure, connector-fixed adapter, connector fixing method, motor, and manufacturing method thereof" Summary of the Invention [Problem to be solved by the invention]

[0004] 4 is an explanatory diagram showing an example of the configuration of a gasket in the above-mentioned patented connector fixing structure, i.e., a conventional connector fixing structure, in which (t) is a top view of the gasket in an upright position, and (x) is a cross-sectional side view taken along the line XX in (t). The gasket 410 that provides waterproofing in the above-mentioned patented connector fixing structure shown in the figure consists of a cylindrical tube portion 42 and, at its ends, a connector fixing flange 43 and a motor fixing flange 44.

[0005] Gasket 410 is handled as follows during the process of fixing the connector to the motor: The lead wires drawn from inside the motor are passed through gasket 410, and then gasket 410 is compressed vertically (in the length direction of the lead wires) to ensure space for connecting the lead wires to the connector.

[0006] However, even if the gasket 410 is formed using a sufficiently flexible or elastic material, its cylindrical shape makes it difficult to compress and deform vertically. In other words, it is often difficult to crush, which reduces workability. Furthermore, because it is difficult to crush, excessive force is applied to the cylindrical portion of the gasket 410 during work, which may damage the cylindrical portion and thereby reduce its waterproofing function. Therefore, there is a need for more efficient work to crush the gasket during the connector connection process.

[0007] The problem that the present invention aims to solve is to eliminate the problems of the prior art and provide a gasket that is easily compressed and deformed in the vertical direction, i.e., a gasket that is easy to crush, during the process of fixing a connector to a motor using the above-mentioned patented connector fixing structure. [Means for solving the problem]

[0008] As a result of studying the above-mentioned problems, the inventors of the present application discovered that forming the cylindrical portion of the gasket into a bellows shape can facilitate the crushing operation and improve the efficiency of the assembly operation, and based on this, they have completed the present invention. That is, the invention claimed in this application, or at least the invention disclosed therein, as a means for solving the above-mentioned problems, is as follows.

[0011] The lead wire insertion gasket, connector fixing structure, and connector-equipped motor of the present invention are configured as described above, and therefore, in the process of fixing a connector to a motor using the patented connector fixing structure, it is possible to facilitate longitudinal compressive deformation of the gasket, i.e., to make it easier to crush, which makes the crushing work easier and improves the efficiency and workability of the assembly work. Furthermore, by making it easier to crush, it is possible to avoid applying excessive force to the tubular portion of the gasket, which prevents deterioration of the waterproof function due to damage to the tubular portion, leading to improved quality.

[0023] FIG. [Figure 3] 1 is an explanatory diagram conceptually showing the configuration of a connector fixing structure of the present invention using a lead wire insertion gasket of the present invention; [Figure 4] 1 is an explanatory diagram showing an example of the configuration of a gasket in a conventional connector fixing structure, in which (t) is a top view of the gasket in an upright state, and (x) is a cross-sectional side view taken along the line XX in (t). DETAILED DESCRIPTION OF THE INVENTION

[0013] The present invention will be described in detail below with reference to the drawings. 1 is an explanatory diagram showing an example of the configuration of a lead wire insertion gasket of the present invention from two directions, in which (t) is a top view of the gasket in an upright position, and (x) is a cross-sectional view taken along the line XX in (t). As shown in the figure, the lead wire insertion gasket 10 is a cylindrical, waterproof gasket through which a lead wire is inserted when connecting the lead wire from a motor to a connector, and is mainly configured as a bellows-like gasket that compresses and deforms in the direction of lead wire insertion.

[0014] The lead wire insertion gasket 10 comprises a cylindrical portion 2, a connector fixing flange 3 provided at each end of the cylindrical portion 2, and a motor fixing flange 4. However, since the cylindrical portion 2 in this example 10 is cylindrical, when (x) is the front view, the left and right side views and the rear view also appear the same as the front view (x). The flanges 3 and 4 also have the same shape, so when (t) is the plan view, the bottom view also appears the same as the plan view (t).

[0015] Figure 2 is a side view illustrating the operation of the lead wire insertion gasket of the present invention shown in Figure 1. The operation of the present invention will be explained in conjunction with Figure 1. With the above-mentioned configuration, the lead wire drawn out from inside the motor can be passed through the cylindrical portion 2 of the lead wire insertion gasket 10 and connected to a connector in a waterproof state.

[0016] As shown in Figure 2, the cylindrical portion 2 of the lead wire insertion gasket 10 is bellows-shaped, allowing it to be compressed and deformed in the lead wire insertion direction. In other words, with the lead wire inserted, the lead wire insertion gasket 10 can be easily crushed in the length direction of the lead wire. This makes it easy to ensure space for connecting the lead wire to the connector, improving the efficiency and workability of the assembly process. Furthermore, because the cylindrical portion 2 of the gasket 10 is easily crushable, it can be deformed without receiving unnecessary force, thereby preventing damage and maintaining good waterproof performance.

[0017] This lead wire insertion gasket 10 connects the motor and connector and is fixed to them. Although the present invention is not limited to this fixing method, as shown in Figure 1, where the flange 3 has fixing screw holes 5, screw fixing is preferably used as the fixing method to the connector or motor.

[0018] FIG. 3 is an explanatory diagram conceptually illustrating the configuration of a connector fixing structure of the present invention using a lead wire insertion gasket of the present invention. In the figure, (a) shows the configuration of the connector fixing structure, and (b) shows its use. The above-mentioned lead wire insertion gasket 10 of the present invention can be used as an improved version of the components constituting the connector fixing structure 20 shown in this figure. The patented connector fixing structure 20 is a structure used when connecting a connector C to a motor M. It is an assembly-type adapter consisting of multiple components 6 and 8, and is used by combining it laterally with the connector C to which the lead wire L from the motor M is connected. It is configured to include a lead wire insertion gasket 10 through which the lead wire L passes and which is housed within the assembly-type adapter after assembly. Although multiple lead wires are shown in the figure, they will be simply referred to as "lead wires L" in this description.

[0019] As shown in the figure, the assembled adapter of the connector fixing structure 20 consists of two mutually engaging members 6, 8 ((a) in the figure). The engagement of the two members 6, 8 forms a housing 15 that houses a lead wire insertion gasket 10 ((b) in the figure), and the lead wire insertion gasket 10 has a lead wire L inserted into its cylindrical portion 2, which connects a connector C to a motor M. The lead wire L is connected in a waterproof state by the gasket 10. Note that a connector-equipped motor 30 equipped with a lead wire insertion gasket 10 is also within the scope of the present invention. [Industrial Applicability]

[0020] The lead wire insertion gasket, connector fixing structure, and connector-equipped motor of the present invention make it easier to crush the gasket during the process of fixing the connector to the motor using the patented connector fixing structure, thereby improving the efficiency and workability of the assembly work and preventing deterioration of the waterproof function. Therefore, this invention has high industrial applicability in the field of motor manufacturing and all related fields. [Explanation of symbols]
