23 strengthen the mechanical structure of lid 13.It also carries at least one of above-mentioned electric connector 16,20.
Advantageously, metal parts 22 and compound component 23 are formed independently of each other, and are then attached relative to one another, such as following
It will be explained in.For example, compound component 23 is made according to molding such as injection molding process.Meanwhile metal parts 22 for example by
Pressed metal plate is made.
Metal parts 22 is formed by being folded the plate 24 that edge 25 surrounds, to limit the hollow portion for accommodating compound component 23
Point.Plate 24 is crossed at least one aperture 26, and an edge in aperture 26 is formed around electric connector 16,20 (more specifically
Part 17) closed perimeter.It should be noted that the latter extends along the axis of the plane extended perpendicular to plate 24, the advantageous Horizon of the axis
Row is in the longitudinal axis X of shell 2.
Fig. 3 more accurately shows the compound component 23 extended in the hollow space of metal parts 22.Compound component 23
It is formed by panel 27, the reinforcer 35 of cell layout is provided on panel 27.Panel 27 is as shown in the illustrative embodiments
The pins 18 of two electric connectors 16,20 cross.Panel 27 further includes the increased thickness of the pin 18 around electric connector.
First embodiment according to Fig.3, electric connector 16 are the single global facility with compound component 23.It is " single
A global facility " is understood to refer to the two parts and forms single component, and the component is not at least one of the two parts
Part cannot separate in the case where damaging.Therefore, the two parts mould simultaneously in the same mold.Therefore, electric connector
16,20 part 17 is the extension of the material of panel 27.
Another embodiment according to Fig.4, electric connector 16,20 may include the face for being attached and being fixed to compound component 23
Base portion on plate 27.In this case, the shape that the opening that panel 27 has has is complementary with part 17, electric connector 16,
20 base portion is resisted against on panel 27.
According to the present invention, a kind of sealing device 28 is provided, extend between hard board 23 and metal plate 22 and is surrounded
The opening of electric power electric connector 16 or the opening for controlling electric connector 20.Such sealing device 28 can be and can deform
So as to against the compliant member of metal parts 22 and compound component 23.For example, which is connector, especially flat
Plain adapter or O-ring.Sealing device 28 can also have the form of adhesive pearl, surround the part 17 of electric connector 16,20
It is deposited on metal parts 22 and/or on compound component 23.
Fig. 2 shows the examples of the component suitable for receiving sealing device 28.According to the example, metal parts 22 is provided with
One groove 29, limits the region for receiving sealing device, which had previously manufactured or recessed first with liquid deposition
In slot 29.The latter is made up of the deformation of the plate 24 of metal parts 22, especially with press machine.First groove 29 is surrounded and is electrically connected
Device is connect, and when sealing device 28 accommodates wherein, moves to and is divided metal parts 22 and compound component 23 by aperture 26
The foreign matter in space and impurity opened are stopped by sealing device 28.
Fig. 4 shows the first face of compound component 23, and when the two parts are put together, this is first facing towards metal parts
22 rotations.The base portion of each electric connector 16,20 is fixed on panel 27 by four clamp devices (such as screw).Each electricity
The base portion of connector 16,20 abuts against the second face of compound component, the second face Control-oriented module 8.Compound component 23 also wraps
It includes and perforates 31 made of its periphery.These perforation 31 form notch, and permission system passes through so that lid 13 to be fastened on shell 2.
According to the diagram in Fig. 4, panel 27 has the section of not reinforcer, and sealing device 28 abuts against the section.It closes
It may include the second groove 32 formed when moulding compound component 23 at component 23.Therefore, which defines in parallel
The channel of hexahedron profile, sealing device 28 can be received in a manner of semiliquid, toppled over or deposited wherein.Finally, Fig. 4 is shown
Two sealing devices 28 each surround dedicated electric connector.
Fig. 5 show from receive Fig. 4 shown in compound component hollow space from the point of view of to metal parts 22.This
First groove 29 at place, which also forms, follows square contour and around the logical of the aperture 26 made of the plate 24 of metal parts 22
Road.Third groove 33 is formed, in plate 24 to receive the sealing device 28 for being exclusively used in control electric connector 20.
According to the present invention it is possible to manufacture one or more first grooves 29, only to receive one or more sealing devices
28, in this case, the support region 34 of the sealing device on compound component 23 is flat.Similarly, lid 13 can be only
One or more second grooves 32 are provided with, are arranged in compound component 23 to receive one or more sealing devices, at this
In the case of kind, the support region of the sealing device 28 on metal parts 22 is flat.According to the combination of these solutions, originally
Invention regulation metal parts 22 and compound component 23 include respectively at least one groove 29,32, for receiving sealing device 28.?
In this case, it would be advantageous to, it is in order to reduce the overall dimensions of the axis X along longitudinal direction of lid 13, the first groove 29 and second is recessed
Slot 32 is arranged facing with each otherly.Therefore, sealing device 28 is between the first groove 29 and the second groove 32.
The lid 13 just described is assembled according to ad hoc approach.It should be noted that this method can be implemented as independently of compressor 1
Lid 13 is manufactured, or is implemented during compressor 1 is installed.
The first step that this method includes is to manufacture metal parts 22 and compound component 23 respectively.This causes two parts to prepare
Good assembling.According to second step, at least one sealing device 28 around electric connector 16,20 be placed on compound component 22 and/
Or on metal parts 22.When sealing device 28 is connector, metal parts 22 is located against on compound component 23 or leaned against
On, such as by being contained in first or second groove 29,32.When sealing device 28 is adhesive pearl or liquid elastomer product
When, it can be deposited on metal parts 22 or on compound component 23 or in both parts.More specifically, the bonding
It is recessed that agent pearl can be deposited on the first groove 29 and/or second generated during the step of manufacture metal parts 22 and compound component 23
In slot 32.According to third step, metal parts 22 is attached on compound component 23, and the latter is contained in by plate 24 and folded edge 25
In the hollow space of the metal parts 22 of restriction.When compound component 23 and metal parts 22 are close together, electric connector 16
Metal parts is crossed in part 17, passes through aperture 26.
In assemble compressible machine 1, lid 13 pre-assembled in this way can be fixed on the shell 2 of compressor 1, to generate pressure
Sealing device 28 is pressed between metal parts 22 and compound component 23 by power, the pressure.It alternatively, can be first by combining unit
Part 23 is located against on the shell 2 of compressor 1, then installs sealing device, and the attachment of metal parts 22 is then leaned against shell 2
On, compound component and sealing device are clipped in the middle.
Due to the lid produced in this way, the sealing of motor compressor is improved.
