Abstract

An improved structure for a quick-connection type connector base comprises an insulation base, a snap, conducting terminals and an elastic pressing sheet. At least three independent containing grooves for the conducting terminals to be inserted in are arranged at the front end of the insulation base, through holes which are correspondingly communicated with the containing grooves and used for directly inserting wires connected with a power supply are arranged at a rear end, and a fixing groove for inserting the snap is arranged at the rear portion of the insulation base. A protruding structure is designed at one end of the snap, and fixing grooves for fixing one sides of the fixed portions at the lower portions of the conducting terminals are further arranged at the bottom of the front end of the insulation base. Each conducting terminal comprises a fixed portion and a contact portion, and a bending structure is arranged at the connecting position of the contact portion and the fixed portion. The quick-connection type connector base overcomes the shortcomings in a traditional connection base structure, one end of the snap is designed into a protrusion of different shapes to achieve the aim that the snap cannot be assembled even reverse operation is performed. In addition, an opening hole of an insulation base in a traditional structure is sealed to achieve the effect of enlarging the insulation distance from a bottom face. The length of a terminal plate is remarkably shortened by improving the design, and use amount of copper materials is reduced by 28.9%.

Description

Speed connects the improvement structure of formula junction block

Technical field

The utility model relates to junction block, and particularly speed connects the improvement structure of formula junction block, is suitable for the junction block of directly pegging graft after the copper conductor peeling that connects power supply.

Background technology

It is traditional widely used air conditioner Electricity Federation parts that speed connects the formula power wiring seat.Ordinary construction is that mains side uses directly to insert after single core copper conductor peeling of

or

and connects; Load-side uses the common sheet that patches to connect, for example #250, #187, #110 or the like.Referring to Fig. 1, Fig. 2, junction block comprises insulating base 1a, gives as security button 2a, conducting terminal 3a, spring clip 4a; Establish at least three storage tank 101a that independently supply conducting terminal 3a grafting usefulness in the insulating base 1a front end, the corresponding direct through hole 102a that pegs graft of lead that storage tank 101a supplies to connect power supply that is communicated with is established in the rear end; Insulating base 1a establishes at the rear portion holddown groove 103a that is communicated with storage tank 101a, supply signature button 2a to plant; Insulating base 1a front bottom end is also established and is supplied the fixing fixing hole 104a of conducting terminal 3a bottom fixed part 301a, and this fixing hole 104a is the open type opening.

There are three big shortcomings in this conventional construction type: the first is given as security button does not have the assembling error correction, when the assembling of this junction block is produced, just might cause afunction or anti-worker refitting with giving as security the anti-dress of button like this.It two is that the barb place of pedestal upper end daughter board is an opening, and this will cause the insulation distance of terminal board and bottom surface shorter relatively.Its three, because of the needs that the female end of #250 is pegged graft, the length of terminal board is longer, the copper product use amount is more relatively.

Summary of the invention

The purpose of the utility model is to design the improvement structure that a kind of speed connects the formula junction block, solves and gives as security button nothing assembling error correction and the relatively short shortcoming of bottom surface insulation distance in the traditional design scheme.

For achieving the above object, the technical scheme of the utility model is:

Speed connects the improvement structure of formula junction block, comprises insulating base, gives as security button, conducting terminal, spring clip; Establish at least three storage tanks that independently supply conducting terminal grafting usefulness in the insulating base front end, the direct through hole of pegging graft of lead that correspondence connection storage tank supplies to connect power supply is established in the rear end, and holddown groove that be communicated with storage tank, the plant of confession signature button is established at the insulating base rear portion; It is characterized in that described signature is detained an end and is designed with an outstanding or bulge-structure, correspondingly, the end that described insulating base rear portion supplies signature to detain the holddown groove of planting is designed to and the structure that should give prominence to or bulge-structure matees.

Further, described insulating base front bottom end is also established and is supplied the fixing fixed groove of conducting terminal bottom fixed part one side, and an end of the said conducting terminal fixed part of this fixed groove of planting is closed in the insulating base.

In addition, described conducting terminal comprises fixed part and contact site, and this contact site and fixed part junction are a bending structure.

The beneficial effect of the utility model:

The utility model has improved the shortcoming in the traditional wired holder structure, an end of giving as security button is designed to difform outstanding, even reach reverse operating also can't organize into; And, make the perforate sealing of the insulating base in the conventional construction, to reach the effect that increases with the bottom surface insulation distance.Through improving design, the length of terminal board significantly shortens, and the copper product use amount has reduced by 28.9%.

Embodiment

Referring to Fig. 3～Fig. 6, the speed of the utility model connects the improvement structure of formula junction block, comprises insulating base 1, gives as security button 2, conducting terminal 3, spring clip 4; Establish at least three storage tanks 101 that independently supply conducting terminal 3 grafting usefulness in insulating base 1 front end; The corresponding through hole 102 that lead that storage tank 101 supplies to connect power supply is directly pegged graft that is communicated with is established in the rear end, and that establish at insulating base 1 rear portion is 101 that is communicated with storage tank, supply to give as security the holddown groove 103 of button 2 plants; Described signature is detained 2 one ends and is designed with an outstanding or bulge-structure 21, and correspondingly, the end that described insulating base 1 rear portion supplies signature to detain the holddown groove of planting 103 is designed to and the structure 1031 that should give prominence to or bulge-structure matees.

Further, described insulating base 1 front bottom end is also established and is supplied the fixing fixed groove 104 of conducting terminal 3 bottom fixed parts 31 1 sides, and an end of said conducting terminal 3 fixed parts 31 of this fixed groove of planting is closed in the insulating base 1.

In addition, described conducting terminal 3 comprises fixed part 31 and contact site 32, and this contact site 32 is a bending structure 33 with fixed part 31 junctions.

The utility model has improved the shortcoming in the traditional wired holder structure, an end of giving as security button is designed to difform outstanding, even reach reverse operating also can't organize into; And, through the fixed groove design, make the perforate sealing of the insulating base in the conventional construction, to reach the effect that increases with the bottom surface insulation distance.Through improving design, the length of conducting terminal significantly shortens, and the copper product use amount has reduced by 28.9%.
