Detailed Description
Detailed descriptions will be given below of embodiments of the present invention. Although the invention will be described and illustrated in connection with certain specific embodiments, it should be understood that the invention is not limited to these embodiments. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the scope of the invention as defined by the appended claims.
Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present invention. It will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known structures and components have not been described in detail so as not to obscure the present invention.
Fig. 1 shows a longitudinal section through a terminal box cover gasket 2. Fig. 2 is a longitudinal section through an upper housing cover 1. Fig. 3 is a longitudinal sectional view of the terminal block cover spacer 2 of fig. 1 mounted on the upper cover 1. The upper housing cover 1 of the compressor shown in fig. 2 is provided with a terminal stud 4, a recess 5 being formed between the outer side of the terminal stud 4 and the surface of the upper housing cover 1. If the terminal box cover gasket 2 of fig. 1 is used to be installed on the upper cover 1 of fig. 2, a gap is left between the terminal box cover gasket 2 and the upper cover 1 at the position of the groove 5, which affects the sealing performance of the gasket on the upper cover 1, thereby reducing the waterproof performance.
Based on this, as shown in fig. 4 and 5, the utility model provides a compressor watertight fittings includes: an upper shell cover 1 of the compressor and a terminal box cover gasket 2. The upper shell cover 1 is provided with a binding post 4, and a groove 5 is formed between the outer side of the binding post 4 and the surface of the upper shell cover 1. In this embodiment, the longitudinal section of the groove 5 is like an inverted cone, wide at the top and narrow at the bottom. This groove 5 does not fit completely with the conventional right angle configuration of the gasket of fig. 1, leaving a gap, thereby reducing the waterproof performance. The terminal box cover gasket 2 of the present invention is different from the terminal box cover gasket 2 of fig. 1, and will be described in detail below.
As shown in fig. 4, the terminal box cover gasket 2 is mounted on the upper housing cover 1, the terminal box cover gasket 2 is provided with a protrusion 6 facing the upper housing cover 1, the protrusion 6 enters the groove 5 to fill the groove 5, so that a gap between the terminal box cover gasket 2 and the groove 5 outside the terminal 4 is greatly reduced, and the sealing performance of the terminal box cover gasket 2 and the waterproof performance of the compressor are enhanced.
In an embodiment, a through hole 3 is formed at a position of the terminal box cover gasket 2 corresponding to the terminal 4, the terminal 4 passes through the through hole 3, and the protrusion 6 is disposed on a side of an inner wall of the through hole 3 facing the upper case cover 1. The inner wall of the through hole 3 can be annular, square or any other shape according to the shape of the binding post 4.
Further, the protrusion 6 is in interference fit with the groove 5. The water-proofing effect is better when the protrusion 6 fills the recess 5 as much as possible. There is the clearance between protruding portion 6 and the recess 5, compares in the structure of fig. 3 can strengthen the leakproofness of terminal box lid gasket 2 to a certain extent to and the waterproof performance of compressor, also belong to the utility model discloses an within the scope of protection, but technical effect does not have protruding portion 6 and recess 5 interference fit good time.
In other embodiments, the terminal box cover gasket 2 and the protruding portion 6 are integrally formed, which is beneficial to reducing the production cost and is simple and convenient to install. For example, the terminal box cover gasket 2 and the protrusion 6 may be integrally formed of an integrally molded rubber member.
Alternatively, the protrusion 6 and the terminal box cover gasket 2 are independent from each other and are used in cooperation, and compared with the above-mentioned integral molding, the advantage that the protrusion 6 and the terminal box cover gasket 2 are independent from each other is that the protrusion 6 can be different according to different compressor models and configurations, and is highly adaptable. During installation, a specific protruding part 6 can be selected to be installed to achieve water proofing, and then the junction box cover gasket 2 is installed, so that the installation of the traditional junction box cover gasket 2 cannot be influenced due to the fact that the protruding part 6 is not matched with the groove 5. Furthermore, the independently mounted protrusion 6 can be more conveniently replaced. The protruding portion 6 and the terminal box cover pad 2 may be adhered to each other to be fixed to each other, or may be fixed to each other by other fastening means. In other alternative embodiments, the projection 6 and the terminal block washer may not be fixedly connected, but the projection 6 and the terminal block washer may also be fixed relative to each other by pressing the washer against the upper housing cover 1.
Optionally, the protruding portion 6 includes a first limiting surface, a second limiting surface and a third limiting surface, the first limiting surface is attached to the outer side of the terminal 4, the second limiting surface is attached to the surface of the upper case cover 1, and the third limiting surface is attached to the terminal box cover gasket 2. If the protruding part 6 and the junction box cover gasket 2 are integrally formed, the first limiting surface is attached to the outer side of the wiring terminal 4, the second limiting surface is attached to the surface of the upper shell cover 1, and the third limiting surface is integrated with the junction box cover gasket 2.
In one embodiment, the groove 5 includes a first side surface and a second side surface which are intersected with each other, when the groove 5 is attached to the protruding portion 6 for use, the first side surface of the groove 5 corresponds to the outer side surface of the terminal 4, the second side surface of the groove 5 corresponds to the surface of the upper case cover 1, and the protruding portion 6 includes a first limiting surface and a second limiting surface which are respectively attached to the first side surface and the second side surface of the groove 5.
In other embodiments, the second side surface of the groove 5 is an inclined surface, the second side surface of the groove 5 is an outward cambered surface, and the second limiting surface is an inward cambered surface. This design is favorable to the second side and the spacing face of second closely laminating, helps water-proof effects.
In another embodiment, the radian of the convex arc surface and the concave arc surface in the longitudinal section of the compressor is A, and the radian of A ranges from 90 degrees to 120 degrees.
Alternatively, the protrusion 6 is a rubber protrusion 6, which is easily deformed and then fills the groove 5, and further helps to prevent liquid from entering the groove 5.
The embodiment of the utility model provides a compressor is still provided, the compressor is equipped with above-mentioned arbitrary compressor watertight fittings.
To sum up, the utility model discloses a compressor watertight fittings compares with compressor including it with prior art, has following advantage:
firstly, the sealing performance of the terminal box cover gasket is enhanced.
And secondly, the integral waterproof performance of the compressor is improved.
The foregoing is a more detailed description of the present invention, taken in conjunction with specific alternative embodiments, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
