The utility model relates to a cassette capacitor. The utility model comprises an outer shell (1), a core (3) and two leading terminals (2). The lower ends of the leading terminals (2) are provided with welding feet and pins. The welding feet are electrically connected with a metal spraying layer (4) on the end face of the core (3). Insertion slots which are matched with the pins are arranged on the outer shell (1). The leading terminals (2) are tightly matched with the insertion slots by the pins and are fixed on the outer shell (1). The utility model realizes that when the cassette type capacitor is produced the leading terminals (2) are changed into the structural positioning from the empirical positioning. The utility model has the advantages of high qualification rate of products, lower cost, low labor intensity of workers, short production periodicity, less material consumption and good production quality.

Description

A kind of boxlike capacitor

Technical field

The utility model relates to a kind of capacitor, especially a kind of boxlike capacitor.

Background technology

At present, boxlike capacitor commonly used is made up of shell, two leading-out terminals, fuses, and leading-out terminal is welded on the gilding layer at fuse two ends by welding foot, again fuse is placed shell, fills with epoxy resin then.There is following shortcoming usually in the capacitor of this structure in manufacture process: when 1, welding leading-out terminal on the gilding layer of capacitor body both sides, be difficult to guarantee that two-terminal upper end level height is identical and be parallel to each other and between two parties, fixedly bring difficulty to fuse; 2, need keep the accurate spacing in both sides and keep the vertical of leading-out terminal by manually installing pad additional at the fixed core period of the day from 11 p.m. to 1 a.m, fully with operating personnel's experience by estimating and manual adjustment, human factor is very outstanding, not only production efficiency is low, product quality is wayward, easily produce waster, labour intensity is big simultaneously, and the production cycle is long.In order to address this problem, the disclosed a kind of boxlike capacitor of Chinese patent ZL03210699, it is to establish a cover plate above the shell of above-mentioned boxlike capacitor, establishes location hole on the cover plate, leading-out terminal passes from location hole, utilizes location hole to reach and makes the leading-out terminal location.Though two leading-out terminals of this boxlike capacitor can obtain the location in the horizontal direction, the experience that remains by the workman in vertical direction realizes the location, and therefore, problem still fundamentally is not resolved.

Summary of the invention

The purpose of this utility model is to provide a kind of boxlike capacitor of novelty, the accurate location that it utilizes structure to locate to realize two leading-out terminals, thus qualification rate height, the production cost of realizing product are low, labor strength is low, the purpose of with short production cycle, good product quality.

By a kind of boxlike capacitor that the utility model proposes, it comprises shell, fuse and two leading-out terminals, the leading-out terminal lower end is provided with welding foot, welding foot is electrically connected with the gilding layer of fuse end face, fuse places in the shell, is filled with epoxy resin between shell and the fuse, and the lower end of leading-out terminal also is provided with pin, have the slot that cooperates with described pin on the shell, leading-out terminal closely cooperates by pin and slot and is fixed on the shell.Adopt said structure, the position of leading-out terminal and highly cooperate the location with slot by its pin, with the location independent of fuse in shell, the leading-out terminal of having realized the boxlike capacitor is located from experience and is changed structure into and locate.

For ease of pin insert slot fixing after, fuse can freely be located, and can make flexible welding foot to welding foot, positioning requirements when so just can guarantee fuse and welding foot well.

Cross the shallow waster that causes for reducing, can on leading-out terminal, be provided with epoxy resin height cue mark owing to annotating the epoxy resin that advances.Behind the epoxy resin height of determining good qualified product, promptly set up epoxy resin height cue mark as standard, when the injection ring epoxy resins,, be qualified product as long as do not have this mark.

For making the utility model be easier to workman's production operation, raise labour productivity, make two grooves identical and be symmetrical distribution in the enclosure, two leading-out terminals are also identical.When producing, can realize leading-out terminal general in slot like this, just can raise labour productivity biglyyer, guarantee the quality of product better.

From the above, because the utility model adopts the structure location to leading-out terminal, thereby make the positioning accuracy of two leading-out terminals be subjected to artificial factor less, production process is further simplified simultaneously, so rate of finished products height, the production cost of product are low, labor strength is low, good product quality.Owing to be provided with epoxy resin height location hole, therefore, reduced because of the very few waster that causes of injection ring epoxy resins again, the qualification rate of product is further enhanced.Simultaneously, leading-out terminal structure of the present utility model is further optimized, and makes the volume of leading-out terminal littler, has saved great deal of raw materials.

Embodiment

The utility model as shown in Figure 1, in the two ends of capacitor case [1] side-lower offer the symmetry two slots [9], the size of slot [9] and pin [6] can closely cooperate, and leading-out terminal [2] can be fixed on the shell.The upper edge of slot [9] closely contacts common accurate location of realizing leading-out terminal [2] with the shoulder [8] of leading-out terminal [2].The height of slot [9] is that the height of leading-out terminal [2] satisfies the requirement of product after pin [6] insertion slot [9] is fixing.Leading-out terminal [2] can adopt monolithic leading-out terminal or biplate leading-out terminal as required.Two leading-out terminals [2] size shape of capacitor is identical.Be provided with welding foot [7] and pin [6] in leading-out terminal [2] lower end.Pin [6] both sides are provided with groove, can play better fixation like this after inserting slot [9].Welding foot [7] is elongated shape, thereby flexible flexible.The naked wire position is provided with epoxy resin height cue mark outside leading-out terminal [2], present embodiment is that the following 1.2mm of naked wire makes at the place epoxy resin height location hole [5] that a diameter is 1mm outside, like this, can indicate the height of the epoxy resin of injection, epoxy resin is filled in the epoxy resin height location hole [5] leading-out terminal [2] has been played further fixation simultaneously.The utility model is when assembling, gilding layer [4] welding of the bottommost of welding foot [7] and capacitor body [3] end face, fuse [3] is placed in the shell [1], and with in pin [6] the insertion slot [9], last injection ring epoxy resins is not crossed epoxy resin height location hole [5], promptly is a qualified capacitor.Because welding foot [7] elastically flexible, therefore, two welding foots [7] are welded on gilding layer [4] and go up height when variant, do not influence the location of leading-out terminal [2], also do not need simultaneously with pad fuse [3] to be done accurately location, so operation are few, and are simple to operate.Welding foot [7], pin [6] and leading-out terminal [2] can direct drawings, so more can reduce production process.
