Description

Insulation systems for electronic equipment

The invention relates to an insulation system for electronic equipment, especially an insulation system for isolating the electrical conduction between the electronic equipment and the testing platform.

Various electronic devices usually need to be tested for their various characteristics by various instruments before they are used or put on the market. For example, the shock resistance of large electronic devices is a very important characteristic for areas located in seismic zones. Therefore, generally speaking, electronic devices need to be placed on a seismic table for shock resistance testing.

However, during the testing process, the electronic equipment is energized and in normal use, and when the seismic station starts to vibrate, it may cause damage to the electronic equipment and cause leakage. If the surface of the seismic station and the electronic equipment is an electrical conductor, it will cause damage to the seismic station due to electrical conduction, resulting in huge losses.

Therefore, there is an urgent need for a novel insulation system for electrically isolating the electronic equipment under test and the test bench without affecting the test results.

A main purpose of the present invention is to provide an insulation system for electronic equipment, which is used to isolate the electrical conduction between the electronic equipment and a test platform, comprising: a bearing seat connected to the electronic equipment, and having a plurality of through holes and a plurality of bolts; an insulating plate, arranged between the bearing seat and the test platform, and having a plurality of perforations; and a plurality of insulating sleeves, sleeved on the outer surface of the bolts. Wherein, the bolt passes through the through hole and the through hole, and is screwed on the test platform, so as to lock the bearing base and the insulating plate on the test platform.

In an embodiment, the insulating plate is made of an insulating material.

In one embodiment, the insulating material is selected from the group consisting of a bakelite board, a wood board, and a plastic board.

In an embodiment, the insulating sleeve is made of a heat-shrinkable film or an insulating paint.

In one embodiment, the insulation system of the electronic equipment further includes a plurality of insulating blocks, each of which includes a through hole, each of the bolts includes a head and a rod, each of the insulating blocks is disposed between the head of each of the bolts and the bearing seat, and the through holes allow the corresponding bolts to pass through.

In an implementation aspect, the insulating block is made of an insulating material.

In one embodiment, the insulating material is selected from the group consisting of a bakelite board, a wood board, and a plastic board.

In an embodiment, the insulation system of the electronic equipment further includes a ground wire connected to the electronic equipment.

In one embodiment, the insulation system of the electronic device further includes a current blocker connected to a power source of the electronic device, the current blocker is set with a allowable current value, and when the current value of the power source exceeds the allowable current value, the current blocker blocks the power source.

The insulation system of the electronic equipment provided by the present invention is mainly used to isolate the electrical conduction between the electronic equipment under test and the test bench. Therefore, during the test, if the electronic equipment is powered on, if there is an accidental leakage or the like, it will not be electrically conducted to the test equipment and its control system, so as to avoid damage to the test equipment and its attached electronic instruments or electrical equipment, and avoid unnecessary losses.

The three-dimensional schematic diagram and the three-dimensional exploded view of the insulation system 1000 of the electronic equipment provided by the present invention are respectively shown in FIG. 1 and FIG. Among them, the The electronic device 2000 is an object to be tested and the test bench 3000 is an instrument for testing the electronic device 2000. In this embodiment, the test bench 3000 is a vibration table for testing the shock resistance of the electronic device 2000 when it is connected to a power supply 2001 to simulate an earthquake.

In detail, the insulation system 1000 of the electronic equipment includes a bearing base 1 , an insulation board 2 , a plurality of insulation sleeves 3 , a plurality of insulation blocks 4 , a ground wire 5 , and a current blocker 6 .

Wherein, the bearing base 1 is connected with the electronic device 2000, and the bearing base 1 includes a plurality of bolts 11 and a plurality of through holes 12, wherein each of the bolts 11 has a head 111 and a rod 112, at least a part of the rod 112 has external threads, and the position of the external threads can be designed according to requirements, and the through holes 12 can have internal threads or not, depending on requirements. In this embodiment, the electronic device 2000 is fixed on the supporting seat 1 , and the fixing method can be a common method in the art, and there is no special limitation. In other embodiments, the supporting seat 1 can be, for example, the base of the electronic device 2000 .

The insulating board 2 is arranged between the supporting base 1 and the test bench 3000, and has a plurality of perforations 21. The insulating board 2 is used to electrically isolate the electronic device 2000 and the test bench 3000. Therefore, it is made of an insulating material, such as bakelite, wood, plastic board and other electrically insulating materials, which can be selected according to requirements. There is no special limitation, as long as the selected insulating board material does not affect the test accuracy of the test bench 3000. For example, when the test bench 3000 is a vibrating table, the selection of the insulating board 2 must not affect the vibration of the electronic device 2000 under test, and must not have the effect of damping or strengthening the vibration. In this case, the insulating board 2 is preferably a bakelite board. And described perforation 21 can have internal thread or not have internal thread, The insulating sleeve 3 is sheathed on the outer surface of the bolt 11. It is sheathed on the shank 112 of the bolt 11, or is sheathed on the head 111 and the shank 112 of the bolt 11. It can be designed according to requirements. The insulating sleeve 3 is also made of an electrically insulating material. In order to ensure that there is no electrical conduction between the bolt 11 and the bearing seat 1, the insulating plate 2, and the test bench 3000 that are in contact with or matched. For example, it can be coated with a heat-shrinkable film or an insulating paint, and the insulating sleeve 3 must conform to the external thread of the rod 112 of the bolt 11 without affecting the cooperation between the external thread of the rod 112 and the internal thread of the corresponding hole.

The setting of the insulating block 4 is to ensure that the head 111 of each bolt 11 will not directly contact the bearing seat 1, so as to avoid electrical conduction. Therefore, similar to the insulating plate 2, the insulating block 4 is made of an insulating material, such as bakelite, wooden board, plastic board and other electrically insulating materials, which can be selected according to requirements, and there is no special limitation.

The grounding wire 5 is connected to the electronic device 2000 and provides a grounding effect to prevent the current generated by the electronic device 2000 from flowing to the test bench 3000 .

The current blocker 6 is connected to the power supply 2001 of the electronic device 2000. The current blocker 6 is set with an allowable current value. When the current value of the power supply 2001 exceeds the allowable current value, the current blocker 6 will block the power supply to avoid damage to the electronic device 2000 or the test bench 3000 when the power supply 2001 generates current pulses.
