Description

A kind of novel breaker

Technical field

The utility model relates to a kind of breakers.

Background technique

Breaker can close, carry and cut-off the electric current under normal loop condition, and close, hold before the deadline The electric current under abnormal loop condition is carried and cut-off, switching device is belonged to, the implementations such as power circuit and motor are protected, thing is avoided Therefore occur.Existing breaker connecting terminal when connecting external wire, peel off by the coat of paint of the end of usual external wire, will reveal More copper wires out are inserted into connecting terminal, then by screwing screw, copper wire is pressed in connecting terminal, and therewith sufficiently Contact, in operation, since connecting terminal caliber size is limited, and more copper wires are scattered distribution the structure, and scattered outside its end It comes, it is difficult to disposably the copper wire of external wire end is fully inserted into connecting terminal, operating efficiency is influenced, screw simultaneously Screw also needs auxiliary tool screwdriver, cumbersome, low efficiency.

Utility model content

For the deficiency in background technique, the utility model provides a kind of novel breaker, and overcomes disadvantages described above.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of novel breaker, including circuit breaker housing and be located at the intracorporal magnetictrip of shell, dynamic/static contact, wiring Terminal, main traverse line, lid, the connecting terminal include the drive rod that pin shaft is fixed on shell and are immobilized in the shell quiet Shell is extended in piece, drive rod one end, and one end is fixed with movable plate corresponding with stationary plate, and the shell is equipped with and passes through for drive rod Strip-shaped hole, drive rod at strip-shaped hole be equipped with sealing element, and between the end and shell be equipped with compression elastic piece；The sealing Part includes support elastic piece and sheet rubber；The lid is equipped with flip lid corresponding with connecting terminal.

The movable plate and stationary plate are equipped with the protrusion of relative engagement.

The housing bottom is equipped with retention bead and sliding part, forms groove between retention bead and shell, on sliding part Conducting bar is slidably matched with shell upper guide groove.

The teeth matched, the fixed rubber block in the conducting bar end are respectively equipped in the conducting bar and guide groove.

Teeth in the guide groove are arranged towards enclosure interior direction.

By adopting the above-described technical solution, when effectively improving existing breaker connecting terminal connection external wire Cumbersome, the problem of low efficiency, the novel breaker is reasonable in design simple, passes through setting push type connecting terminal and connects External wire, it is easy to operate, it is connected firmly, installation effectiveness is high；Fixed locating part is set simultaneously, it is solid convenient for the installation of breaker Fixed, disassembling operations are simple and fast.

Specific embodiment

With reference to Fig. 1 combination Fig. 2, Fig. 3 it is found that the utility model: a kind of novel breaker, including circuit breaker housing 1 and position In magnetictrip 2, dynamic/static contact 3, connecting terminal 4, main traverse line 5, lid 13 in shell 1, the connecting terminal 4 includes pin Shell 1, one end are extended in the drive rod 41 that axis is fixed on shell 1 and the stationary plate 42 being fixed in shell 1,41 one end of drive rod It is fixed with movable plate 43 corresponding with stationary plate 42, the shell 1 is equipped with the strip-shaped hole 6 passed through for drive rod 41, and drive rod 41 leans on It is equipped with sealing element 7 at nearly strip-shaped hole 6, and is equipped with compression elastic piece 14, the work of compressed elastic component 14 between the end and shell 1 With movable plate 43 and stationary plate 42 are inconsistent.The sealing element 7 includes support elastic piece 71 and sheet rubber 72, when driving drive rod 41 When, sealing element 7 is mobile with drive rod 41, and by the effect of support elastic piece 71, sheet rubber 72 is always and in shell 1 in moving process Wall fitting.

The movable plate 43 and stationary plate 42 are equipped with the protrusion 40 of relative engagement, and in not connected external wire, protrusion 40 is kept away Exempt from movable plate 43 and stationary plate 42 relatively moves, keeps opposing stationary, falling off because of external vibration effects accessory is prevented, thus shadow Ring service life；When connecting external wire, protrusion 40 is interspersed in mostly with for promptly copper wire, preventing external lead between copper wire Line falls off, and is connected firmly.

1 bottom of shell is equipped with retention bead 8 and sliding part 9, and groove 81 is formed between retention bead 8 and shell 1, sliding Conducting bar 91 is slidably matched with 1 upper guide groove 11 of shell on moving part 9.

The teeth 10 matched, the fixed rubber block in 91 end of conducting bar are respectively equipped in the conducting bar 91 and guide groove 11 911, when installation, rubber block 911 is pressed against in fixed plate 12, plays the role of buffering and protection conducting bar 91 and fixed plate 12.

Teeth 10 in the guide groove 11 are arranged towards 1 internal direction of shell, which prevents sliding part 9 from falling back, To not have fixed effect；During installation, sliding part 9 is slid along guide groove 11 to 12 direction of fixed plate.

The lid 13 is equipped with flip lid 131 corresponding with connecting terminal 4, it is preferable that 131 one end of flip lid and lid 13 are cut with scissors It connects in succession, it is preferable that hinge connection is used, by opening flip lid 131, by the connecting pin of external wire from 4 side of connecting terminal It is put into, closes flip lid 131, it is swift to operate.

When connecting terminal 4 connects external wire, external wire is enameled wire, peels off the outer layer insulation skin of its end, is exposed The conducting wire of its internal more copper wires composition, opens flip lid 131, while 41 end of drive rod of shell 1, drive rod are extended in pressing The movable plate 43 of 41 other ends is forced away from the movement of stationary plate 42, and the terminals for peelling off insulating layer are put into from open flip lid 131 Between sound piece, the pressing to 41 end of drive rod is unclamped, the power of 41 compression elastic piece 14 of drive rod resets, the end of external wire Portion is compressed between sound piece, closes flip lid 131, and the attended operation of external wire is completed.

When fixed breaker, it is preferable that fixed plate 12 is bar shaped setting, the groove 81 that retention bead 81 and shell 1 are formed It is placed in the side of fixed plate 12, sliding part 9 is slid along 11 phase retention bead of guide groove, 81 direction, until fixed plate 12 is placed in groove In 81, and 911 overhead of rubber block, in the other side of fixed plate 12, by 12 stuck fast of fixed plate, fixed operation is completed.The structure Setting is avoided when multiple breakers are fixed side by side, and all dismountings on side when needing to dismount, need to just may be used by in-between one It is fixed in fixed plate 12 with sliding in order, it is easy to operate, it is connected firmly.

Cumbersome, efficiency when the utility model effectively improves existing breaker connecting terminal connection external wire Low problem, the novel breaker is reasonable in design simple, connects external wire, operation by setting push type connecting terminal Simply, it is connected firmly, installation effectiveness is high；Fixed locating part is set simultaneously, is fixed convenient for the installation of breaker, disassembling operations are simple Fast.

Every technical staff's notice: although the utility model is described according to above-mentioned specific embodiment, this The invention thought of utility model is not limited to that utility model, and any repacking with inventive concept will all be included in this specially In sharp scope of patent protection.
