Description
Technical field
The utility model relates to capacitor arrangement and manufacturing technology field, particularly a kind of capacitor plastic casing.
Background technology
Existing terminal is drawn square plastic case capacitance device with the structural representation of shell as shown in Figure 1.It is made up of housing A, inner chamber B and mounting ear C.Capacitor body is pressed into fuse in the inner chamber of shell after having welded leading-out terminal, and terminal is irrigated epoxy resin then in the length direction both sides, and resin solidification forms capacitor.This kind shell mechanism is simple, and the die sinking cost is lower, and Shooting Technique is also easy to control.But when making the production capacitor, there is following shortcoming.
(1) the terminal position consistency can't guarantee: because of terminal is the capacitor body two metal spraying faces that are welded on, because of there is the deviation of size in fuse, the weld jig deviations causes two leading-out terminals on the fuse to have height, all around deflection.When embedding is assembled, do not have positioning function, more be prone to the terminal height because of shell, all around skewness, this just requires the operative employee that terminal is proofreaied and correct.Come the height of control terminal by the manual synchronizing terminal, all around deflection problem can't guarantee consistency of product, and exist proofread and correct, the overcorrect phenomenon.The manual synchronizing terminal, production efficiency is low first, second has product devious.The product deviation is slight, and the client has complaint, and the product quality image is impaired.Serious client's rejected product causes unnecessary loss.
(2) content of epoxy resin is bigger, the cost height: existing shell product is the right angle corner shape around the bottom, and the lower end of the capacitor body of the shell inner cavity of packing into is a circular arc.Therefore, there is bigger space in the right angle corner position around outer casing bottom.This part space is filled by epoxy resin when encapsulated epoxy resin, and the effect of the epoxy resin of this part filling is just filled the space, replaced the air-gap of product inside.This just causes the product amount of epoxy to increase, and product cost rises.
The utility model content
The purpose of this utility model is to provide a kind of capacitor plastic casing, mainly solves in the existing product leading-out terminal and is prone to terminal height, deflection all around, is difficult for the problem of location.The orientation problem in the manufacture process particularly, it not only has advantages of good positioning effect to leading-out terminal on the capacitor, but also can significantly improve operator's production efficiency.
For achieving the above object, the technical solution of the utility model is.
A kind of capacitor plastic casing, it comprises housing and has the mounting ear of screw mounting hole, it is characterized in that: the length direction both sides inwall correspondence of the upper end square orifice of described housing is provided with the terminal position support body, and this terminal position support body is made of three parallel ribs of the interval setting of vertical direction; The rib upper end of described both sides has inside rectangular indentation respectively, be respectively equipped with the protuberance of position correspondence in the breach, form the terminal position groove in the terminal position frame inner chamber between the rectangular indentation, form the terminal anticreep projection of terminal position frame inner chamber between the described protuberance, the terminal position platform of terminal position frame inner chamber is formed on described rectangular indentation bottom, and formed location notch is applicable to two filling-in bit terminal forms on the rib of both sides; Rib top in the middle of described three parallel ribs has opening upwards, and rib formed location notch principle in both sides is identical under its positioning principle, is applicable to that just difference draws the terminal of form---single filling-in bit terminal; Described terminal position platform is positioned at terminal anticreep projection below; It between terminal position platform and the inwardly protruded terminal anticreep projection high and low position terminal fixed interval of control fixed terminal.
Described capacitor plastic casing is characterized in that: described housing bottom is a circular arc, and the outside is provided with bottom support frame and bottom support attached frame bar at the bottom of the circular arc; The bottom support chord position is in the housing bottom middle part, and it and mounting ear inner side edge connect and compose stable hollow water surface base jointly; The connecting portion of bottom support frame and mounting ear extends the bottom support attached frame bar that is the L type respectively to the mounting ear both sides; The bottom support attached frame bar bottom surface of L type and hollow water surface base end face constitute the support bottom surface jointly.
Described capacitor plastic casing is characterized in that: be provided with reinforcement in the described housing.
By said structure, the utlity model has following advantage.
When 1, the utility model uses, be pressed into shell behind the capacitor body welding leading-out terminal, have positioning strip on the leading-out terminal.The terminal position bar places the terminal position frame inner chamber of shell, and terminal position front and back and left and right directions are fixed.Simultaneously the terminal position bar is depressed on the terminal position platform, and top is fixing by terminal anticreep projection, uses left and right sides two-terminal above-below direction to be fixed and is in same position.
2, outer casing bottom of the present utility model is designed to circular arc, reduces the outer casing bottom redundant space, has reduced epoxy resin can amount.Because bottom design is a circular arc, product can't keep flat or be fixing.For addressing this problem, outer setting has bottom support frame, bottom support attached frame bar at the bottom of circular arc.Bottom support frame, bottom support attached frame bar are in same plane with fixed installation eardrum portion, guarantee product placement and fixedly the time product be in stable state.
