The mounting surface of the plastic shell is usually not a plane, the stress direction is complex, if the sealing ring is not completely pressed into the equipment shell, the connector plastic shell cannot be completely attached to the equipment shell, and if the torque is applied to the fastening bolt 4, the plastic shell is cracked due to uneven stress on the surface of the plastic shell, waste products are easily generated, and the production cost is increased; although this problem can be controlled to some extent by the constraints of the assembly instructions, the level of operators varies widely from production to after sales, and it is difficult to fully train, so that it is difficult to avoid such problems with existing mounting structures.
Disclosure of Invention
The application aims to solve the technical problem of providing a through hole connector plastic shell mounting structure, which eliminates the technical requirements on operators and reduces the rejection rate during mounting by arranging a turning plate and a boss which are matched with each other so as to solve the defects that the assembly personnel level difference of each stage of the product in the prior art is large and the mounting quality cannot be ensured.
The application is realized in the following way: the utility model provides a via hole connector moulded case mounting structure, includes casing installation face and moulded case, equipment via hole and bolt hole have been seted up on the casing installation face, be equipped with on the moulded case with equipment via hole matched with sealing washer, set up the mounting hole corresponding with the bolt hole on the moulded case, a holding chamber has been seted up to the bottom of mounting hole, the bottom surface of mounting hole is by turning over the board shutoff, turn over the board and hold the chamber cooperation, still be provided with the boss corresponding with holding chamber on the casing installation face; when the sealing ring is pressed into the device through hole to enable the shell mounting surface to be completely attached to the plastic shell, the lug boss presses the turning plate into the accommodating cavity to enable the mounting hole to be communicated with the bolt hole.
The boss is clung to the top surface of the periphery of the bolt hole.
The holding cavity is a triangular cavity with side walls communicated with the mounting holes and an opening at the bottom, the turning plate is arranged at the opening at the bottom of the holding cavity, and the top of the turning plate stretches into the mounting holes so that the fastening bolts cannot enter the bolt holes through the mounting holes.
The boss is a triangular pyramid body formed by naturally extending the outer wall of the bolt hole upwards.
The top of the turning plate slightly stretches into the mounting hole to block the fastening bolt.
According to the through hole connector plastic shell mounting structure, the turning plate and the boss are matched with each other, when the shell mounting surface is not attached to the plastic shell, the turning plate can block the mounting hole to prevent the fastening bolt from extending into the bolt hole, when the sealing ring is completely pressed into the equipment through hole to enable the shell mounting surface to be completely attached to the plastic shell, the boss can squeeze the turning plate to enable the mounting hole to be communicated with the bolt hole, at the moment, the fastening bolt can be smoothly inserted, the technical requirement on an operator is eliminated, the rejection rate in mounting is reduced, and further the production cost is reduced.

Detailed Description
The application will be further illustrated with reference to specific examples. It is to be understood that these examples are illustrative of the present application and are not intended to limit the scope of the present application. It is also to be understood that various changes and modifications may be made by one skilled in the art after reading the description herein, and that such equivalents are intended to fall within the scope of the application as defined in the appended claims.
Example 1
As shown in fig. 2 and 3, a through hole connector plastic shell mounting structure comprises a shell mounting surface 1 and a plastic shell 2, wherein a device through hole 5 and a bolt hole 6 are formed in the shell mounting surface 1, a sealing ring 7 matched with the device through hole 5 is mounted on the plastic shell 2, a mounting hole 3 corresponding to the bolt hole 6 is formed in the plastic shell 2, a containing cavity 8 is formed in the bottom of the mounting hole 3, the bottom surface of the mounting hole 3 is blocked by a turning plate 9, the turning plate 9 is matched with the containing cavity 8, and a boss 10 corresponding to the containing cavity 8 is further arranged on the shell mounting surface 1; when the sealing ring 7 is pressed into the device through hole 5 to enable the shell mounting surface 1 to be completely attached to the plastic shell 2, the boss 10 presses the turning plate 9 into the accommodating cavity 8 to enable the mounting hole 3 to be communicated with the bolt hole 6.
In this embodiment, in order to ensure that the boss 10 can correctly push the flap 9 open and press into the cavity 8, the boss 10 is tightly attached to the top surface of the outer circumference of the bolt hole 6.
