Abstract
The utility model discloses a box type ultraminiature metallized film capacitor, which is characterized in that the upper end of a lead wire (5) of the capacitor is clamped through a lead wire clamping piece (6), and the lower end is embedded in the upper part of the capacitor; and epoxy resin (4) is poured into the inner bottom of a plastic housing (1). In the utility model, epoxy resin serves as pouring material, bumps are designed on the plastic housing, and the assembly work can be accomplished without other auxiliary assembly facilities, so that the product is ensured that the position of the lead wire conforms to the process requirements, the leak tightness and the insulating property of the product are enhanced, the process is simplified, the product quality and the qualification rate are improved, and the manufacturing cost and the environment pollution are reduced.
Description
Technical field: the utility model relates to a kind of boxlike microminiature metallic film capacitor.
Background technology: boxlike microminiature metallic film capacitor, of many uses, the huge market demand, but because its overall dimension is little, the mode that adopts lead-in wire to hang usually during the product assembling is assembled, this just requires shell firmly to link together with fuse.To fulfill this requirement, generally adopt at present and inject earlier a certain amount of PUR in the enclosure, assemble then, utilize the viscosity of PUR to make fuse and shell link together through heating.
Employing PUR assembling not only needs to be equipped with PUR firing equipment and pouring member, and because the PUR fusion temperature is wayward, and higher will to cause fuse to be connected with shell insecure, may cause shell to come off; PUR wire drawing will cause pouring into the time on the low side causes product appearance bad, even pollutes machine or work top, also may interrupt assembling work because of pouring head stops up.In addition, because the thickness of general fuse is little more many than the inboard width of shell, therefore assembling back fuse is amesiality easily, cause the product lead-in wire crooked, the position of the clamping of influence lead-in wire and product lead-in wire, thus cause waster, assembling work efficient and qualification rate are reduced, increased product cost.
The utility model content: the purpose of this utility model is to overcome the drawback that present employing PUR assembles, a kind of PUR assembly system of saving is provided, realize that fuse well contacts with shell, guarantee to assemble the perfusion operation and carry out smoothly, and can reduce the boxlike microminiature metallic film capacitor of product cost.The technical scheme that the utility model adopted is: described capacitor lead wire 5 upper ends are with lead-in wire holding piece 6 clampings, and the lower end is embedded in capacitor upper, and with epoxy resin 4 device for casting at plastic casing 1 inner bottom part.
The beneficial effects of the utility model are: owing to the space that utilizes between bulge, adopt epoxy resin as pouring material, and do not have other materials of PUR and so on, so significantly improved the sealing and the insulation property of product, reduced environmental pollution.Owing to designed bulge at plastic casing,, do not produced extra charge once being not need other auxiliary assembling facility or material can finish assembling work, simplified program, improve product quality and qualification rate, saved facility, material and electric expense, reduced production cost.The 2nd, when fuse is blocked in bulge, not only make the fuse position be in the central authorities of shell horizontal direction, and make lead wire successfully to be clamped to lead-in wire, guaranteed that the position of product lead-in wire meets technological requirement.

Fig. 3 is the end view of Fig. 2
Fig. 4 is that the A-A of Fig. 2 is to view
Embodiment: shown in Fig. 1 figure, 2 figure, 3 figure, 4, described capacitor lead wire 5 upper ends are with lead-in wire holding piece 6 clampings, and the lower end is embedded in capacitor upper, and with epoxy resin 4 adhering devices at plastic casing 1 inner bottom part.
Shown in Fig. 1 figure, 2 figure, 3 figure, 4, described plastic casing 1 has the inboard of two sides or each side to be provided with two bulges 2 and corresponding mutually, and each bulge 2 is positioned at the middle position, the left and right sides of half side, and bulge 2 can extend downwardly into plastic casing 1 bottom.
Shown in Fig. 1 figure, 2 figure, 3 figure, 4, the bulge 2 of described each side has two at least.
Shown in Fig. 1 figure, 2 figure, 3 figure, 4, described bulge 2 is strip projected parts, two bulge 2 width and highly all equal.
Shown in Fig. 1 figure, 2 figure, 3 figure, 4, described plastic casing 1 is the boxlike rectangle.
Design principle of the present utility model is: because the shell wall of plastic casing is thinner, there is elasticity, and the oral area of plastic casing is unaffected, so the fuse at this thickness range all can insert in the plastic casing smoothly, and because the elasticity of plastic casing wall and fuse being blocked securely by bulge.Can realize that so, then fuse and the good of shell are connected.Because small product size is little, the total amount of shell and first pass perfusion resin is less, can not come off at first pass perfusion rear casing.After the first pass perfusion, because resin solidification only combines shell and fuse, shell more can not come off in the subsequent job process.
