Abstract
The utility model discloses a kind of detector for electric fire protection shell, including the probe body and plastic protection plate that are made up of plastic front board, plastic casing, described plastic protection plate is by plastic protection plate wide and the vertical l-shaped member being integrally formed of narrow plastic protection plate；Described plastic protection plate fixed packet is covered and is arranged on probe body rib, and multiple U-shaped line outlet grooves for clamping binding post are offered on narrow plastic protection plate, and multiple U-shaped line outlet grooves are uniformly arranged.The protective plate that the utility model passes through the setting L-type on plastic casing, equally distributed multiple U-shaped wire holes are set up on L-type protective plate, projection is set up on U-shaped wire hole, so that the creep age distance of protective plate is greatly increased, so that when the object of static electrification comes close to or in contact with shell, can effectively prevent electrostatic from discharging crust of the device internal electronic component, and cause electronic component to puncture the situation of failure.
Description
Technical field
The utility model is related to electric fire monitoring system equipment technical field, more particularly to a kind of electrical fire monitoring to visit
Survey device shell.
Background technology
At present, the electronics dress being monitored with the presence or absence of leaky to electric loop is used in electric fire monitoring system
Put referred to as detector for electric fire protection（Hereinafter referred to as detector）.In old standard GB/T 14287-2005, to detection
The external connection line of device does not do the EMC tests such as static discharge, therefore to shell without electrostatic protection requirement.But in new state
In family standard GB14287-2014, the EMC tests such as static discharge to be done to above-mentioned connecting line, if outside not to detector
Shell does electrostatic protection treatment, when ESD test is done almost absolutely internal electronic component punch through damage.
Utility model content
The purpose of this utility model is to provide a kind of detector for electric fire protection shell, can adapt to the object of static electrification
When coming close to or in contact with shell, can effectively prevent electrostatic from discharging crust of the device internal electronic component, and cause electronic component
Puncture the situation of failure.
The technical solution adopted in the utility model is：
A kind of detector for electric fire protection shell, including the probe body being made up of plastic front board 1, plastic casing 2
With plastic protection plate 3, described plastic protection plate 3 is by plastic protection plate wide and the vertical L being integrally formed of narrow plastic protection plate
Shape component；The described fixed packet of plastic protection plate 3 is covered and is arranged on probe body rib, and is offered on narrow plastic protection plate many
The individual U-shaped line outlet groove 5 for clamping binding post, and multiple U-shaped line outlet grooves 5 are uniformly arranged.
The notch of described U-shaped line outlet groove 5 is provided with boss.
The utility model sets up equally distributed by the protective plate of the setting L-type on plastic casing on L-type protective plate
Multiple U-shaped wire holes, projection is set up on U-shaped wire hole, so that the creep age distance of protective plate is greatly increased, so as to reach with quiet
Electrostatic induced current will not be transmitted directly on circuit board by binding post when electric object contacts, is close to or works, can be effective
Prevent electrostatic from discharging crust of the device internal electronic component, and cause electronic component to puncture the situation of failure.

Fig. 1 is side view of the present utility model；
Fig. 2 is rearview of the present utility model；
Fig. 3 is top view of the present utility model；
Fig. 4 is the structural representation of the utility model use state.
Specific embodiment
As shown in Figure 1,2 and 3, the utility model include the probe body that is made up of plastic front board 1, plastic casing 2 and
Plastic protection plate 3, described plastic protection plate 3 is by plastic protection plate wide and the vertical L-shaped being integrally formed of narrow plastic protection plate
Component；The described fixed packet of plastic protection plate 3 is covered and is arranged on probe body rib, and offers multiple on narrow plastic protection plate
It is uniformly arranged for the U-shaped line outlet groove 5 of clamping binding post, and multiple U-shaped line outlet grooves 5.
It is normal when using, as shown in figure 4, plastic casing 2 is built with 7 circuit boards, have on 7 circuit boards 8 electronic components and
For the binding post of external connection.The outer layer of the wire 4 drawn from binding post is wire (insulating barrier), with antistatic energy
Power, is drawn by the U-shaped line outlet groove 5 on plastic protection plate 3.There is the presence of plastic protection plate 3 so that do ESD test
Static discharge head on instrument increases to the distance of binding post metal part 6, and electrostatic is unable to reach binding post during experiment
Metal part 6, electrostatic also cannot from the electronic component 8 that the metal part 6 of binding post is passed on circuit board 7 so that
It is prevented effectively from punch through damage of the electrostatic to electronic component 8.
The notch of described U-shaped line outlet groove is provided with boss, by setting boss so that the thickness increase of protective plate,
Also the creep age distance of protective plate is further increased, makes electrostatic protection grade higher.
