Abstract
The utility model discloses a metallized film capacitor shell which is characterized in that two opposite inner walls of the shell are respectively provided with a lead fastening groove. when a chip with leads welded at two ends is placed in the shell, the lead fastening grooves on the inner walls of the shell will form location fit with chucking lugs on the leads by the limit effect of the lead fastening grooves on the inner walls of the shell so as to prevent the chip from moving back and forth or side to side in the shell. Thus, the chip can be conveniently and rapidly placed and located in the shell, thus raising production efficiency. In the meantime, as the positions of the lead fastening grooves on the inner walls of the shell and the positions of the chucking lugs on the leads are all preset, the chunking lugs on the leads will form location fit with the lead fastening grooves on the inner walls of the shell so as to rise location accuracy of the position of the chip of a metallized film capacitor and finally make the chip to be arranged at the center of the shell.
Description
Technical field
The utility model relates to the technical field of electronic component, and more particularly, the utility model relates to a kind of housing of metallization film capacitor.
Background technology
Metallization film capacitor has that volume is little, capacity is large, nonpolarity, encapsulation is reliable, insulation impedance is high, frequency characteristic is excellent, dielectric loss is very little, electric property is stable, can advantages such as " self-healings ", therefore, metallization film capacitor is widely used in the fields such as electronics, computer, communication, space flight, military affairs.
Existing metallization film capacitor has generally comprised housing, fuse and two lead-in wires, when making metallization film capacitor, at first, two lead-in wires is welded on respectively on two end faces of fuse; Then, the fuse that is welded with lead-in wire is put into housing; Then, pour into encapsulating material in housing; After encapsulation material solidifies, metallization film capacitor just completes.
At present, the inwall of existing its housing of metallization film capacitor is all generally planar structure, when the fuse that is welded with lead-in wire when two ends is put into housing and encapsulated, need to repeatedly adjust, proofread and correct the position of fuse, thereby make the accurate positioning of fuse, so just can have influence on production efficiency; Again due to the adjustment of fuse position, proofread and correct and generally manually carry out, so the accurate positioning of its fuse of existing metallization film capacitor position is lower.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of housing of metallization film capacitor, this housing can make fuse be positioned at exactly in housing quickly and easily, thereby improved production efficiency, simultaneously, also improved the accurate positioning of its fuse of metallization film capacitor position.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of housing of metallization film capacitor is characterized in that: respectively be provided with a lead-in wire screens groove on relative two inwalls of described housing.
When the fuse that is welded with lead-in wire when two ends is put into housing, position-limiting action by the lead-in wire screens groove on inner walls, lead-in wire screens groove on inner walls just can coordinate with the chucking lug location on lead-in wire, thereby prevent that fuse from front and back occuring or move left and right in housing, like this, fuse just can be laid quickly and easily, be positioned in housing, thereby has improved production efficiency;
Simultaneously, the position of going up chucking lug due to position and the lead-in wire of the screens groove that goes between on inner walls is all pre-set, so, location by lead-in wire screens groove on go between upper chucking lug and inner walls coordinates, thereby improved the accurate positioning of its fuse of metallization film capacitor position, finally made the fuse be arranged on the center position of housing.
As preferred structure of the present utility model, the lead-in wire screens groove on described inner walls preferably arranges vertically.
Because the lead-in wire screens groove on inner walls arranges vertically, so, when the fuse that is welded with lead-in wire is put into housing, chucking lug on lead-in wire just can be inserted in lead-in wire screens groove and along lead-in wire screens groove and slide, thereby make the fuse that is welded with lead-in wire can lay quickly and easily, be positioned in housing, improved production efficiency.
The utility model beneficial effect against existing technologies is:
Owing to respectively being provided with a lead-in wire screens groove on relative two inwalls of its housing of this metallization film capacitor, so, when the fuse that is welded with lead-in wire when two ends is put into housing, position-limiting action by the lead-in wire screens groove on inner walls, lead-in wire screens groove on inner walls just can coordinate with the chucking lug location on lead-in wire, thereby prevents that fuse from front and back occuring in housing or move left and right, like this, fuse just can be laid quickly and easily, be positioned in housing, thereby has improved production efficiency; Simultaneously, the position of going up chucking lug due to position and the lead-in wire of the screens groove that goes between on inner walls is all pre-set, so, upper chucking lug just can coordinate with the location of lead-in wire screens groove on inner walls by going between, thereby improved the accurate positioning of its fuse of metallization film capacitor position, finally made the fuse be arranged on the center position of housing.
In addition, the housing of this metallization film capacitor also have simple in structure, reasonable in design, cost of manufacture is low, be easy to the advantages such as popularization.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment;
The cut-away view that Fig. 2 is the utility model preferred embodiment when the lead-in wire location coordinates.
Embodiment
As shown in Figure 1 and Figure 2, the housing of the metallization film capacitor in this preferred embodiment, it is characterized in that: respectively be provided with a lead-in wire screens groove 110,120 on relative two inwalls 11,12 of above-mentioned housing 1, lead-in wire screens groove 110 on above-mentioned housing 1 inwall 11 arranges vertically, and the lead-in wire screens groove 120 on above-mentioned housing 1 inwall 12 arranges vertically.
When two ends are welded with lead-in wire 2 fuse 3 and put into housing 1, position-limiting action by the lead-in wire screens groove 110,120 on housing 1 inwall 11,12, lead-in wire screens groove 110,120 on housing 1 inwall 11,12 just can coordinate 20 location of the chucking lug on 2 with lead-in wire, thereby prevent fuse 3 in housing 1 interior generation front and back or move left and right, like this, fuse 3 just can be laid quickly and easily, be positioned in housing 1, thereby has improved production efficiency;
Simultaneously, due to the position of lead-in wire screens groove 110,120 on housing 1 inwall 11,12 with go between that the position of chucking lug 20 is all pre-set on 2, so, on chucking lug 20 and housing 1 inwall 11,12, the location of lead-in wire screens groove 110,120 coordinates by going between on 2, thereby improved the accurate positioning of its fuse of metallization film capacitor 3 positions, finally made the fuse 3 be arranged on the center position of housing 1.
Two because the lead-in wire screens groove 110,120 on housing 1 inwall 11,12 arranges vertically, so, when the fuse 3 that is welded with lead-in wire 2 is put into housing 1, chucking lug 20 on lead-in wire 2 just can be inserted in lead-in wire screens groove 110,120 and along lead-in wire screens groove 110,120 and slide, thereby make the fuse 3 that is welded with lead-in wire 2 can lay quickly and easily, be positioned in housing 1, improved production efficiency.
The above is only preferred embodiment of the present utility model, is not to limit practical range of the present utility model; Be all equivalents of doing according to claim scope of the present utility model, be claim scope of the present utility model and cover.
