Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
In the present invention, when not doing contrary explanation, the nouns of locality be included in term such as " inside and outside " only represents the orientation of this term under normal service condition, or being commonly called as those skilled in the art's understanding, and should not be considered as the restriction to this term.
See Fig. 1, the invention provides a kind of noinductive capacitor, noinductive capacitor comprises base, the inner casing 1 covered by base and the shell 2 being sheathed on inner casing 1 outside, airtight to form cavity 3 by base between inner casing 1 and shell 2; Shell 2 is circumferentially provided with becket 9 and is provided with multiple pressure inductor 4 in cavity 3, shell 2 outer wall is provided with the warning device and pressure display unit 6 that are electrically connected to each other; Pressure inductor 4 is electrically connected with pressure display unit 6 by becket 9, and pressure display unit 6 can slide on the outer wall of becket 9 along shell 2 circumferential direction.
By technique scheme, shell 2 is set in inner casing 1 outside, and uses base by airtight for the uncovered position of the two; Pressure inductor 4 is electrically connected with pressure display unit 6 as conductor by the annular sheet metal on shell 2, pressure inductor 4 senses the pressure size in the cavity 3 between shell 2 and inner casing 1, to be reflected in time on pressure display unit 6 so that Timeliness coverage hidden peril of explosion getting rid of, to prevent internal pressure from increasing further.Due to pressure display unit 6 can on becket 9 outer wall circumferentially direction slide, such convenience is pressure size in multi-angle monitoring capacitor in use, Timeliness coverage solves in time, prevents blast from occurring to cause to the electronic devices and components around capacitor to damage to increase production cost.
In present embodiment, for the ease of immediately detecting the pressure size in capacitor in multiple position simultaneously, prevent undetected test leakage, preferably, multiple pressure inductor 4 is arranged on the inwall of shell 2.
The sealing property of cavity 3 affects the normal detection of noinductive capacitor, sealing property as cavity 3 is not good, pressure in the cavity 3 that pressure inductor 4 induces is less than normal, even if the critical value arriving blast can not Timeliness coverage, finally cause the generation of exploding, in order to avoid the generation of this situation, preferred inner casing 1 and shell 2 are cylindric, and an end face is uncovered, base is seal cover 10, and seal cover 10 covers the open-mouth welded seal that are located at inner casing 1 and shell 2.
In order to save time, ensure the good sealing property after welding while accelerating speed of welding, preferably, being welded as ultrasonic bonding.Adopt this welding machine mode not only with low cost, reduce production cost, and cleanliness without any pollution, can not disfiguring workpiece.
In addition, the pressure size sensed is shown by pressure display unit 6 by pressure inductor 4 in time, in cavity 3, diverse location is due to various ectocine (as moist, high temperature) difference, cause the pressure size of diverse location also not identical, for ease of a point position probing analysis, preferably, multiple pressure inductor 4 is connected in series with pressure display unit 6 respectively.
To produce or noise in environment for use can produce interference to the sense of hearing of tester or user, the dust spread everywhere or steam can affect their vision, cause them can not the hidden peril of explosion of Timeliness coverage capacitor, in order to address this problem, preferably, warning device is audible-visual annunciator 5.
Blast when the pressure size in cavity 3 exceedes critical value, the fragment produced to make blast concentrates injection towards the top of capacitor, four loose can not clash into the impaired inefficacy of other electric elements caused around capacitor, preferably, as shown in Figure 3, the outer wall on the top of shell 2 and/or inwall are provided with multiple strip groove 7.Like this, during pressure increase in cavity 3, easier when extruding the top of shell 2 its bursting is formed breach, now the part of capacitor internal just outwards can be sprayed by this breach, can not affect the electronic component around capacitor.
Before above-mentioned breach is formed, in order to ensure the sealing of cavity 3, when avoiding capacitor to use, top collision produces deformation, and preferably, the length of strip groove 7 is 0.5-0.6 times of shell 2 diameter.
In addition, for increasing the mechanical strength of shell 2, the sidewall of shell 2 when occurring that makes to explode can not break and the top comparatively cracky of shell 2, and preferably, as shown in Figure 2, the inwall of shell 2 and/or outer wall are provided with many strip reinforcements 8.
Below the preferred embodiment of the present invention is described in detail by reference to the accompanying drawings; but; the present invention is not limited to the detail in above-mentioned execution mode; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition, each concrete technical characteristic described in above-mentioned embodiment, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the present invention illustrates no longer separately to various possible compound mode.
In addition, also can carry out combination in any between various different execution mode of the present invention, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
