Description
Technical field
The present invention relates to the electric connecting part of electric circuit on/off conversion, particularly a kind of electric connecting mechanism for abstractable breaker.
Background technology
It is 03219862.0 that the Intellectual Property in China net discloses a kind of patent No. on March 10th, 2004, denomination of invention is the patented technology of electric connecting mechanism for abstractable breaker, as shown in Figure 1, it comprises the bus 7 that is fixed on the drawout chassis underframe, body bus 25 and be connected with bus 7 touch bridge 1, described bus 7 is provided with the raised line of two guide rail shapes, on guide rail raised line two sides, be provided with arc groove 6,2, be provided with circular arc projection 9 with the arc groove corresponding fixed chuck that touches the bridge lower end that matches, 28, make the fixed chuck that touches bridge 1 lower end patch the axle that connects into horizontal direction and cooperate with bus guide rail raised line two sides.Its weak point: big at interval between the guide rail raised line on (1) bus, drawout chassis bus binding post volume is increased, cause corresponding connection conductive pieces volume also to increase, increase consumable quantity, also increased simultaneously the connection contact-making surface of conducting system, cause that heating increases, product heats up, and influence is electrically connected performance.(2) when body bus and the generation skew of pull-out type bus position, touch bridge meeting deflection certain angle, the contact area of pull-out type bus and contact chip is obviously reduced, can cause that equally heating increases, the product intensification, influence is electrically connected performance.When (3) the body bus inserted, four contact-making surfaces contacted simultaneously, and operating physical force is very big.
Summary of the invention
The objective of the invention is to design a kind of compact conformation, economize material, be electrically connected the good electric connecting mechanism for abstractable breaker of performance.
In order to achieve the above object, the present invention adopts following technical solution: a kind of electric connecting mechanism for abstractable breaker, it comprises the bus that is fixed on the drawout chassis underframe, the body bus reaches the bridge that touches that is connected with bus, wherein touching bridge is made of two row's contact chips, it is the semicircular elongated slot of opening shape that the upper end that it is characterized in that described bus is provided with a cross section, the cell body outer surface is two sections faces of cylinder on the same cylinder, described two rows are close together between the adjacent interior contact chip in the contact chips face-to-face flexibly, the elongated groove shaft of chuck and bus upper end is connected in the lower end, the chuck inner surface is an arc surface outside the out-connecting contact lower end, cooperates with the cell body outer cylinder surface to contact.
Because the present invention has adopted a kind of inside and outside double fastener to hold the electrical connection mechanism of coaxial line contact, it is good to be electrically connected performance, and two clamping contact bindiny mechanisms are close together, compact conformation, volume is little, has saved valuable electric conducting material, simultaneously, also reduce drawout chassis bus binding post and connected contact-making surface, further guaranteed to be electrically connected performance.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail.
Fig. 1 is a prior art structure reference diagram.
Fig. 2 is the stereochemical structure combination decomposition figure of present embodiment.
Embodiment
As shown in Figure 2, present embodiment comprises the bus 1 that is fixed on the drawout chassis underframe, body bus 18 and be connected with bus 1 touch bridge 2, wherein touch bridge 2 by two row's contact chips (3,5), (4,6) constitute, it is the semicircular elongated slot 13 of opening shape that described bus 1 upper end is provided with a cross section, the cell body outer surface is two sections faces of cylinder 11 on the same cylinder, 12, the elongated slot 13 and the cell body outer surface face of cylinder 11,12 is coaxial, interior contact chip 6, chuck 10 is connected with 13 of the elongated slots of bus 1 upper end in 5 lower ends, out-connecting contact 4, chuck 8 inner surfaces are arc surface outside 3 lower ends, with cell body external cylindrical surface 11,12 cooperate contact.
Because it is coaxial that inside and outside double fastener is held structure, when bus 1 and the 18 generation skews of body bus, touch bridge 2 and all remain unchanged with bus 1 inside and outside contact-making surface, guaranteed the good performance that is electrically connected.Simultaneously,, reduce contact resistance, on the face of cylinder 11,12, be respectively equipped with groove 14,15 in order to guarantee the contact-making surface of bus 1 outer surface (face of cylinder) 11,12 and two exclusive contact chips 3,4.
Described two row's contact chips (3,5), (4,6) are assembled in the support 20, reduced the assembling manufacturing procedure, the upper and lower part of interior contact chip 6,5 opposite faces and bus 1 vertical line have angle, form the V-shape angle in making between contact chip 6,5 opposite faces upper and lower, link together by compression spring 21 pretensions face-to-face between them.It is a pair of that each compresses spring 21 to the contact chip dress, and every pair of compression spring 21 is installed in 22 places, hole between the contact chip in two rows, because the elastic force of spring makes interior contact chip 5,6 outwards form pressure.Under the state that withdrawable circuit breaker connects, guarantee that bus 1 and the body bus 18 on 5,6 pairs of drawout chassis underframe of contact chip respectively has 4 contact-making surfaces into and out of line in two exclusive contact chips 3,4 and two rows, and enough contact pressures are arranged, and patch laborsaving like this.In addition, the outermost contact wire 16 of chuck 9 and body bus 18 is lower than the outermost contact wire 17 of outer chuck 7 in out-connecting contact upper end and body bus 18 in interior contact chip 5,6 upper ends, when body bus 18 is inserted, inside and outside contact chip upper grip 7,9 substeps contact with body bus 18, in the outer earlier back, rapid operation.
In addition,, reduce the temperature rise of lead, be provided with and touching the corresponding opening 19 in space between the bridge 2 on the body bus 18 in order to help the circulation of air.
In sum, the present invention compared with prior art has the following advantages:
1, rapid operation.
2, volume is little.
3, contact resistance is low.Under the situation that does not increase physical dimension, contact-making surface has increased by one times, has reduced contact resistance, has improved the performance of product, does not increase the consumption of copper material simultaneously.
4, processing and matching requirements reduce.Scheme provided by the invention has overcome the loose contact that is caused by the foozle of product component, influences switching performance anything but when the insertion position skew occurring, does not increase the resistance when inserting.
