Description
Technical Field
The utility model relates to a sealed field, more specifically say, relate to a quick sealed flange device of low atmospheric pressure environment.
Background
When the electronic equipment is detected in a low-pressure environment, a temperature-high comprehensive environment and a temperature-humidity-high comprehensive environment, the power-on detection of the tested equipment is inevitable, and because the test cable interfaces of the tested equipment are not uniform, the interface type flange is poor in universality and high in cost; the general sealing method for testing the cable mostly adopts a baffle plate mode or a mud sealing mode, and has poor reliability, poor high temperature resistance and high rework rate.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that, overcome the not enough that exists among the prior art, provide a quick sealed flange device of low atmospheric pressure environment.
The utility model relates to a quick sealed flange device of low atmospheric pressure environment realizes through following technical scheme, including flange and sealed gasbag, the flange comprises main part flange and flange base, and sealed gasbag is located main part flange downthehole, and sealed gasbag is hollow barrel, and flange base is global to be provided with the mounting groove, and sealed gasbag air inlet passes the main part flange and is connected with sealed gasbag.
The utility model discloses a main part flange seals the gasbag and constitutes, and the external air supply system of gasbag reaches the sealed to the test cable. Wherein, the test cable passes through the through wires hole of gasbag, and the flexibility of pressurization back gasbag can be fine parcel test cable, and the leakproofness is good. The internal portion of main part flange increases group's screw thread, can effectively prevent the relative displacement that sealed gasbag leads to under the effort of the inside and outside atmospheric pressure difference of proof box. The sealing air bag is made of high-temperature-resistant rubber, and can meet high-temperature stress examination in a temperature-high comprehensive environment and a temperature-humidity-high comprehensive environment.
Compared with the prior art, the beneficial effects of the utility model are that:
the device is used for testing the sealing of the cable aiming at the tested equipment, and has the advantages of simple method, economy, practicality, repeated use and high return on investment. The complex sealing process is not needed, the disassembly is simple, and the time cost can be saved.
The sealed gasbag takes off from the main part flange, and the test cable passes sealed gasbag through wires hole, reserves the cable of enough length after, will seal the gasbag dress back in the main part flange, and the mounting groove of rethread flange is connected main part flange and proof box test hole through the buckle, and gas supply system pressurizes sealed gasbag through sealed gasbag air inlet, beats to enough pressure after, can detect.

Detailed Description
In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in detail with reference to the accompanying drawings and detailed description. In addition, the embodiments and features of the embodiments of the present application may be combined with each other without conflict. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, and the described embodiments are merely some embodiments, rather than all embodiments, of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
The following is further described with reference to the accompanying drawings.
The utility model discloses as shown in fig. 1-2, a quick sealed flange device of low atmospheric pressure environment, including flange and air bag, the flange comprises main part flange and flange base, and air bag is located main part flange downthehole, and air bag is hollow barrel, and flange base is global to be provided with the mounting groove, and the air bag air inlet is passed the main part flange and is connected with air bag.
The utility model discloses a main part flange seals the gasbag and constitutes, and the external air supply system of gasbag reaches the sealed to the test cable. Wherein, the test cable passes through the through wires hole of gasbag, and the test cable is wrapped up that the flexibility of gasbag can be fine after the pressurization, and the leakproofness is good. The internal part of the main body flange is provided with the group of threads, so that the relative displacement of the sealing air bag caused by the acting force of the air pressure difference inside and outside the test box can be effectively prevented. The sealing air bag is made of high-temperature-resistant rubber, and can meet high-temperature stress assessment under a temperature-high comprehensive environment and a temperature-humidity-high comprehensive environment.
The utility model discloses the use as follows:
will seal airbag 1 takes off from main part flange 2, and the test cable passes seal airbag through wires hole 5, reserves the cable of enough length after, will seal airbag 1 dress back to main part flange 2, and rethread main part flange mounting groove 4 is connected main part flange 2 and proof box test hole through the buckle, and air supply system pressurizes seal airbag 1 through seal airbag air inlet 3, suppresses to enough pressure after, can detect.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and embellishments can be made without departing from the principle of the present invention, and these modifications and embellishments should also be regarded as the protection scope of the present invention.
