Abstract
The utility model relates to an electric connection structure for a removable circuit breaker, which comprises at least one pair of elastic pieces, wherein, the front ends and the rear ends of the elastic pieces are connected through leads; in addition, a cushion block is clamped and fixed between the elastic pieces, so that a front clamping mouth and a rear clamping mouth are respectively formed through the front ends and the rear ends of the elastic pieces. The electric connection structure has the advantages as follows: the structure is firm and reliable, the stability is good, the installation size is small, the current-carrying capability is convenient to increase and decrease under the premise that the structure size is not changed.
Description
Technical field
The utility model relates to a kind of electric connection structure that is used to be electrically connected, and is specially adapted to withdrawable circuit breaker, belongs to electric field.
Background technology
Being electrically connected between withdrawable frame circuit breaker body and the drawer is by the smoking, insert and realize of conductive structure, this contact generally includes a fixed terminal, and is referred to as the busbar of slotting tool and can realizes between fixed terminal and the slotting tool that the structure that is electrically connected realizes.Generally speaking, fixing mounting terminal is installed on the drawer, and the one end is connected with bus-bar in the distribution loop, and the other end is connected with electric connection structure with drawer; And slotting tool is installed on the body of circuit breaker, and the one end is connected with the conductive structure of circuit breaker inside, and the other end is connected with electric connection structure with drawer, thereby realizes the conductive structure of breaker body inside and the connection between the bus-bar in the distribution loop.
From the above, drawer is to connect the bus-bar in intrinsic conductive structure of withdrawable circuit breaker and the distribution loop with the effect of electric connection structure.In addition, the body of withdrawable circuit breaker need plug in drawer, the conducting system of body can not adopt modes such as welding or bolted to be connected with bus-bar, and oxidation all may take place in the used metal of electric conductor in air, and conductive structure to bear electric current by the time electric repulsion, so adopt elastic construction to come the electric connection structure between body and the drawer is produced the syndeton mode that certain pressure is undoubtedly a kind of optimum.
According to above-mentioned requirement, determine that the drawer type electric connection structure that withdrawable circuit breaker is used should have following characteristics: 1, this structure can the load-bearing breaker predetermined electric current, 2, slotting tool is inserted very easily with extracting out realizes being connected and separating of circuit breaker electric syndeton, 3, with being connected of slotting tool in certain pressure can be arranged so that it is cracked and make contact resistance minimum to make electric conductor be used for the oxide layer on surface of coupling part.5, for the conforming as far as possible consideration of the parts of circuit breaker design, the design of this electric connection structure seriation as much as possible is so that processing cost is minimum.To sum up, the described structure of this utility model just has very large meaning and initiative.
The utility model content
In view of above-mentioned, the utility model proposes a kind of electric connection structure that is used for withdrawable circuit breaker, it can reach the requirement of above-mentioned body and the electric connection structure between the drawout chassis at withdrawable circuit breaker.
The purpose of this utility model is achieved through the following technical solutions:
A kind of electric connection structure that is used for withdrawable circuit breaker is characterized in that:
This structure comprises at least one pair of flexure strip, connects lead between the front and back end of this flexure strip;
Insert and put fixedly cushion block between the described a pair of flexure strip, thereby make the front-end and back-end of a pair of flexure strip constitute fore-clamp mouth and back folder mouth respectively.
Further:
The fixed terminal that also comprises at least one conduction usefulness, two faces of this fixed terminal contact with described back folder mouth.
Also comprise at least one slotting tool, this slotting tool can insert in the described fore-clamp mouth.
Plurality of advantages such as the utlity model has that sound construction is reliable, good stability, installation volume be little, and do not changing under the size prerequisite of structure, and the ducting capacity increase and decrease is convenient.

Fig. 2 connects the lead aspect graph for flexure strip;
Fig. 3 connects the cushion block schematic diagram between a pair of flexure strip;
Fig. 4 is that the fore-clamp mouth cooperates schematic diagram with slotting tool;
Fig. 5 is fixing terminal structure figure;
Fig. 6 is that back folder mouth combines figure with fixed terminal.
Embodiment
The utility model provides a kind of electric connection structure that is mainly used in withdrawable circuit breaker, and this structure comprises at least one pair of flexure strip, connects lead between the front and back end of this flexure strip; Insert and put fixedly cushion block between the described a pair of flexure strip, thereby make the front-end and back-end of a pair of flexure strip constitute fore-clamp mouth and back folder mouth respectively.
As shown in Figure 1, flexure strip 6 is the sheet body structure, and its front and back end has crack in a row equably, forms the elasticity fingertip 3 of many disjunctors.
As shown in Figure 2, all connect conductive contact 2, connect one between two conductive contacts 2 of every elasticity fingertip 3 and make the lead 4 that conductive path is used in the front and back end of every elasticity fingertip 3.
As shown in Figure 3, between a pair of flexure strip, insert and put and fix 7 cushion blocks, make the front-end and back-end of a pair of flexure strip constitute fore-clamp mouth and back folder mouth respectively.
As shown in Figure 4, fore-clamp mouth and slotting tool 1 cooperate.As shown in Figure 6, folder mouth in back is installed on the fixed terminal 5.
By case study on implementation described above is made amendment, following case study on implementation can also be arranged:
Fixed terminal shown in Figure 5 is produced a plurality of projection 8, the flexure strip that cushion block is installed shown in Figure 3 of many covers is installed on projection, form the conductive path of many groups etc.
What need statement is; the foregoing description only is used for the utility model is described but not the utility model is limited; therefore; for a person skilled in the art; under the situation that does not deviate from the utility model spirit and scope, it is carried out various conspicuous changes, all should be within protection range of the present utility model.
