Abstract
The utility model gives a kind of sensor glass sealed base for expanding chute with oiling, including base housing and some leads, base housing is provided with through thereon, an oil-filled hole of lower surface and some mounting holes, the mounting hole and some leads are one-to-one relationship, the lead penetrating mounting holes, and be tightly connected between lead and corresponding mounting hole by glass insulator；Base housing is provided with oil guide groove on away from the side end face of sensor internal chamber one, and oil-filled hole is extended on the cell wall of oil guide groove bottom away from the side opening of sensor internal chamber one.By increasing oil guide groove on oil-filled hole, make oil there is sufficient space to trickle during being filled with, accelerate oil-filled speed, improve efficiency, and after the oil-filled end of job, fluid is voluntarily in flow sensor internal chamber.
Description
Technical field
It the utility model is related to a kind of sealing base of sensor, more particularly to a kind of controllable silicon for expanding chute with oiling
Pressure sensor glass sealed base.
Background technology
Controllable silicon pressure sensor uses Silicon pressure chip, is needed after the completion of chip package again oil-filled as pressure in cavity
Power transmitting medium, but in Oil feeding process, due to sticky, oil-filled hole and the very little of oil, trickle and have some setbacks when oil-filled, oil-filled effect
Rate is relatively low.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of oiling simple in construction, that water conservancy diversion effect is good that carries and expanded
The sensor glass sealed base of chute.
In order to solve the above technical problems, the utility model provide it is a kind of with oiling expand chute sensor glass it is close
Pedestal, including base housing and some leads are sealed, base housing is provided with through thereon, an oil-filled hole of downside and some installations
Hole, the mounting hole and some leads are one-to-one relationship, the lead penetrating mounting holes, and lead and corresponding mounting hole
Between be tightly connected by glass insulator；
Base housing is provided with oil guide groove on away from the side end face of sensor internal chamber one, and oil-filled hole is away from sensor internal
The side opening of chamber one is extended on the cell wall of oil guide groove bottom.
After such structure, by increasing oil guide groove on oil-filled hole, oil is set to have sufficient sky during being filled with
Between trickle, accelerate oil-filled speed, improve efficiency, and after the oil-filled end of job, fluid voluntarily flow sensor internal chamber
In.
Understand technology contents of the present utility model in order to clearer, the sensor that this is expanded to chute with oiling below is used
Glass sealed base is referred to as this sealing base.
The oil guide groove of this sealing base is kidney slot；After such structure, the shape and structure of oil guide groove is more reasonable.
The oil guide groove length direction of this sealing base is consistent with the radial direction of base housing；After such structure,
Oil guide groove can more fully collect fluid, facilitate fluid flow sensor internal chamber.
Brief description of the drawings
Fig. 1 is the sectional view of this sealing base embodiment front view.
Fig. 2 is Fig. 1 top view.
Embodiment
As shown in Fig. 1 to 2
This sealing base includes base housing 1 and five leads 2.
The generally cylindrical body shape of base housing 1, the upper and lower end face of base housing 1 have encapsulation notch 11a, 11b, up and down
Two encapsulation notch 11a, 11b position correspondences, but the two does not extend through the upper and lower end face of base housing 1, is provided with base housing 1
One oil-filled hole 12 and five mounting holes, oil-filled hole 12 connect two encapsulation notch 11a, 11b, an oil-filled hole 12 with mounting hole
It is distributed with five mounting holes along the axis uniform circular of base housing 1.
Five mounting holes and five leads 2 are one-to-one relationship, and every lead 2 runs through corresponding mounting hole, and lead 2
Sealed between corresponding mounting hole by glass insulator 3.
Oil guide groove 13 is provided with the encapsulation notch 11a bottom walls on the top of base housing 1, this encapsulation notch 11a is in away from biography
The side position of sensor internal chamber one, side opening is extended on the bottom cell wall of oil guide groove 13 on oil-filled hole 12, and oil guide groove 13 is kidney-shaped
Groove, the length direction of oil guide groove 13 are consistent with the radial direction of base housing 1.
In use, this sealing base is arranged in controllable silicon pressure sensor, by increasing oil guide groove on oil-filled hole 12
13, make oil there is sufficient space to trickle during being filled with, accelerate oil-filled speed, improve efficiency, and in the oil-filled end of job
Afterwards, accelerate in top encapsulation notch 11a inner fluid flow sensor internal chambers.
Above-described is only a kind of embodiment of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of the utility model principle is not departed from, some variations and modifications can also be made, these also should be regarded as
Belong to the scope of protection of the utility model.
