Description

Technical Field

[0001] The utility model relates to the technical field of the sealing structure of electrical equipment, and particularly relates to a connector installation module. Background Art

[0002] LRM connectors, namely long-distance multi-mode connectors, are widely used in the aviation field. LRM connectors are used to connect functional boards. The LRM connectors, the functional boards, and the housing used to assemble the LRM connectors and the functional boards form an LRM module, that is, a connector installation module. As disclosed in a new type of LRM module package in the Chinese utility model patent with the authorization announcement number CN218526585U, it includes a module housing, a module cover plate fixed to the module housing, a functional board card encapsulated in the cavity formed by the module housing and the module cover plate, and an LRM plug connector installed on the rear end face of the module housing and fixed to the functional board card. One side of the module housing is integrally hollowed out and a rubber strip installation groove is reserved at the edge. The module cover plate is installed on the hollowed-out side of the module housing and fixed by screws. A conductive sealing rubber strip is installed between the module housing and the module cover plate. The conductive sealing rubber strip is installed in the rubber strip installation groove of the module housing, so that the module cover plate and the module housing are sealed through the conductive sealing rubber strip. Composite conductive rubber strips are installed around the housing of the LRM plug connector. After the LRM plug connector is installed on the rear end face of the module housing, the housing of the LRM plug connector and the module housing are sealed through the composite conductive rubber strips. The contact part between the composite conductive rubber strips and the conductive sealing rubber strips around the module housing is fixed by gluing. The conductive sealing rubber strips are connected to the composite conductive rubber strips to seal the module cover plate, the connector housing, and the module housing. The module housing and the module cover plate together form a module outer shell. A sealed cavity is formed between the module cover plate and the module housing. The functional board card is encapsulated in the sealed cavity formed by the module cover plate and the module housing, so that the LRM module package has independent electromagnetic shielding and sealing performance.

[0003] Among them, in order to ensure the reliable fixation and sealing between the connector and the module housing, the connector housing and the cover plate of the module housing are tightly connected by screws. The screws form fasteners. There are screw through-holes on the module cover plate, and threaded holes are provided on the connector housing. The screws pass through the screw through-holes on the module cover plate and are threadedly connected into the threaded holes on the connector housing, so that the module cover plate presses the sealing strip on the connector housing. In order to avoid the part of the connector housing where the threaded holes are provided occupying the space on the side of the mating end of the connector, the threaded holes are arranged at the tail close to the functional board card facing away from the mating end. The threaded holes on the connector housing are located on the inner side of the sealing strip on the connector housing close to the sealing cavity. Correspondingly, the sealing strip cannot seal the screw connection part between the connector housing and the cover plate of the module housing. Currently, for the sealing of the screw connection part between the connector housing and the module housing, sealant is used to smear the peripheral gap of the screw. This method causes inconvenience to maintenance disassembly. The sealant sticks the screw firmly. When disassembling the module housing, the sealant must be destroyed and removed, and the operation is relatively inconvenient, affecting work efficiency, and even damaging the connector housing or the module housing.

[0028] In the connector mounting module of the present utility model, a sealing ring for the fastener to pass through is provided between the connector housing and the module housing. After the connector housing and the module housing are tightly connected by the fastener, the sealing ring can be pressed between the connector housing and the module housing. The sealing ring seals around the fastener, isolating the gap formed by the fastener passing through the module housing from the inner cavity of the module housing, sealing and isolating the fastener installation space from the inner cavity of the module housing, and using the sealing ring to seal the fastener connection part between the connector housing and the module housing. When repairing and disassembling the connector mounting module, the sealing ring here can be reused, which is convenient for repair and disassembly operations.

[0029] Embodiment of the connector mounting module of the present utility model:

[0030] Such as Figure 1 , Figure 2As shown, the connector mounting module includes a connector 1, a printed circuit board 100, and a module housing. The module housing includes a module shell 2 and a module cover plate 3. The connector 1 is connected to the printed circuit board 100 and fixedly installed within the module housing. The connector 1 is a rectangular connector 1 and is also an LRM connector 1. On one side wall of the module shell 2, there is a connector mounting groove 22. On another side wall, the module cover plate 3 is covered. The module cover plate 3 is fixedly connected to the corresponding side wall of the module shell 2 by a first screw 4. On the side wall of the module shell 2 where the module cover plate 3 is fixed, there is a side opening 21. The side opening 21 communicates with the connector mounting groove 22 for the connector 1 to be inserted into the module shell 2. The side wall of the module shell 2 where the module cover plate 3 is fixed is perpendicular to the side wall where the connector mounting groove 22 is provided. The direction in which the connector 1 is inserted into the module shell 2 is perpendicular to the plugging direction of the connector 1 and is consistent with the direction in which the side opening 21 in the module shell 2 penetrates inward. After the connector 1 is installed on the module shell 2, the module cover plate 3 is then covered to form a closed cavity. After the module cover plate 3 is fixedly connected to the connector housing 11 and the module shell 2, the sealing between the connector 1 and the module shell 2 and the module cover plate 3 and the continuity of electromagnetic shielding are achieved.

[0031] The connector mounting groove 22 penetrates along the plugging direction of the connector 1. The notch of the connector mounting groove 22 communicates with the side opening 21. The connector 1 is inserted into the connector mounting groove 22 from the notch and is supported on the bottom of the connector mounting groove 22. The connector 1 has an outer end extending out of the module shell 2 from the connector mounting groove 22 and an inner end extending into the module shell 2. The inner end of the connector 1 is used to connect the printed circuit board 100 within the module shell 2. The outer end of the connector 1 is a plugging end for plugging with a mating electrical component.

[0032] The connector 1 includes a connector housing 11 and a contact component 12. The contact component 12 is arranged within the connector housing 11. To reliably fix the connector 1, the connector housing 11 is fixedly connected to the module cover plate 3 by a second screw 5 and is fixedly connected to the module shell 2 by a third screw 6. The second screw 5 and the third screw 6 are respectively connected to opposite sides of the connector housing 11. On the module cover plate 3, there are screw through holes 31 corresponding to the first screw 4 and the second screw 5 respectively. The first screw 4 passes through the module cover plate 3 and is connected to the module shell 2. The second screw 5 passes through the module cover plate 3 and is connected to the connector housing 11. On the bottom of the connector mounting groove 22 of the module shell 2, there is a through hole for the third screw 6 to pass through so that the third screw 6 passes through the module shell 2 and is connected to the connector housing 11.

[0033] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown, a seal 13 is provided on the outer side surface of the connector housing 11. The seal 13 is an annular rubber ring. The seal 13 is arranged around its center line, and the extending direction of the center line of the seal 13 is the same as the insertion direction of the connector 1. The connector installation groove 22 of the module housing 2 and the module cover plate 3 enclose an installation opening for the insertion end of the connector 1 to extend out. The bottom wall, side wall of the connector installation groove 22, and the part of the module cover plate 3 opposite to the bottom wall of the connector installation groove 22 together form the inner wall at the installation opening of the module housing. The seal 13 is used to form a seal between the connector housing 11 and the inner wall at the installation opening of the module housing, that is, the seal 13 forms a sealing fit with the groove wall of the connector installation groove 22 and the module cover plate 3. A seal strip installation groove 23 is provided at the edge of the side opening 21 on the module housing 2, and a seal strip 7 is provided in the seal strip installation groove 23. The seal strip 7 is used to form a seal between the module cover plate 3 and the module housing 2, and the seal 13 is connected to the seal strip 7 to ensure continuous sealing.

[0034] The second screw 5 and the third screw 6 constitute fasteners for fixedly connecting the connector housing 11 and the module housing. The module cover plate 3 and the module housing 2 enclose the inner cavity of the module housing. To save space, the second screw 5 and the third screw 6 are located inside the seal 13 close to the inner cavity of the module housing. In this way, the seal 13 cannot seal the connection part of the second screw 5 and the third screw 6. Therefore, a sealing ring 14 for the fasteners to pass through is provided between the connector housing 11 and the module housing. The sealing ring 14 seals the connection part of the fasteners between the connector housing 11 and the module housing. Sealing rings 14 are respectively provided at the second screw 5 and the third screw 6. The sealing ring 14 is used to seal between the connector housing 11 and the module cover plate 3 at the second screw 5 and to seal between the connector housing 11 and the module housing 2 at the third screw 6, preventing water vapor from entering the inner cavity of the module housing through the gap between the corresponding screw and the hole, isolating the gap formed by the fasteners passing through the module housing from the inner cavity of the module housing. The sealing ring 14 seals the connection part of the fasteners between the connector housing 11 and the module housing, with reliable sealing. When repairing and disassembling the connector installation module, the sealing ring 14 here can be reused, facilitating the repair and disassembly operation.

[0035] A sealing groove 111 is provided on the connector housing 11, and the sealing ring 14 is arranged in the sealing groove 111. The plate surface of the module cover plate 3 facing the module housing 2 constitutes a sealing surface for pressing the sealing ring 14 at the second screw 5 into the corresponding sealing groove 111. The bottom surface of the connector installation groove 22 of the module housing 2 constitutes a sealing surface for pressing the sealing ring 14 at the third screw 6 into the corresponding sealing groove 111. By arranging the sealing groove 111 on the connector housing 11, the structure of the module cover plate 3 can be simplified, facilitating production.

[0036] The connector housing 11 is provided with connection holes 114 for respectively threadedly connecting the second screw 5 and the third screw 6. At each connection hole 114, a sealing groove 111 is coaxially provided. The sealing groove 111 is an annular groove arranged around the center line of the connection hole 114. The center line of the connection hole 114 is perpendicular to the insertion direction of the connector 1. The sealing groove 111 and the connection hole 114 are spaced apart to prevent the sealing ring 14 from rubbing against the thread of the screw and being damaged. The sealing ring 14 is adhesively fixed in the sealing groove 111, which is convenient for disassembly and assembly operations. The sealing groove 111 is arranged on the inner side of the seal mounting groove 112 close to the inner cavity of the module housing. The groove wall of the sealing groove 111 is provided with a notch 113 to communicate the seal mounting groove 112 with the sealing groove 111, which is convenient for machining the seal mounting groove 112 and the sealing groove 111 on the connector housing 11. The depth of the sealing groove 111 is less than the depth of the seal mounting groove 112, which is convenient for the sealing groove 111 to accommodate the sealing ring 14 with a smaller size and the seal mounting groove 112 to accommodate the seal 13 with a larger size.

[0037] The sealing ring 14 is used to seal the connection parts of the second screw 5 and the third screw 6 inside the seal 13. For the first screw 4, the first screw 4 constitutes a fastening connecting piece for fixedly connecting the module cover plate 3 and the module housing 2. Since it is arranged outside the sealing strip 7, the gap at the first screw 4 can be isolated by relying on the sealing strip 7, and there is no need to make a separate seal, which can simplify the installation structure.

[0038] The first screw 4, the second screw 5, and the third screw 6 have the same specifications. The screws are countersunk head screws, and each screw includes a threaded part and a head part. The threaded part of the first screw 4 is used to connect to the fixing hole of the module housing 2, and the threaded parts of the second screw 5 and the third screw 6 are used to connect to the connection holes 114 of the connector housing 11. The head part of the screw presses against the module housing. The through hole on the module housing for the screw to pass through is adapted to the countersunk head screw and has a space for the head part of the screw to sink into the through hole, preventing the screw from protruding and occupying space. The connection holes 114 of the connector housing 11 and the through holes on the module housing constitute a fastener installation space. The connection holes on the connector housing for screw threaded connection and the holes on the module housing for screw threaded connection are both blind holes. The threaded parts of the second screw 5 and the third screw 6 are provided with anti-loosening glue. The anti-loosening glue here plays an anti-loosening role and does not need to consider sealing. When disassembling the screw, there is no need to perform special cleaning, preventing the screw from loosening, ensuring the sealing performance, and being beneficial to reliable sealing.

[0039] In other embodiments, the sealing groove for installing the sealing ring may not be provided, and the opposite two planes of the module housing and the connector housing can clamp the sealing ring to achieve the sealing effect.

[0040] In other embodiments, the seal mounting groove can also be separated from the sealing groove.

[0041] In other embodiments, the depth of the sealing groove may also be the same as the depth of the seal mounting groove.

[0042] In other embodiments, the sealing groove may also communicate with the connection hole.

[0043] In other embodiments, the connector housing may also be fixedly connected to the module cover plate only by screws.

[0044] In other embodiments, the fastener may also be a hexagon head bolt.

[0045] In other embodiments, the sealing groove may also be provided on the module housing; the sealing groove may also be provided on both the connector housing and the module housing, and the sealing grooves of the connector housing and the module housing correspond to each other and are jointly used for installing the sealing ring.

[0046] In other embodiments, the sealing groove may also be provided on the module housing, and the sealing ring (14) is bonded in the sealing groove on the module housing.
