Interpretation of structure is carried out successively for above structure：
A, theme framework is one connecting terminal of merging on the basis of breaker body, then connecting terminal setting anode
Conducting wire access aperture and cathode conductor access aperture, corresponding lead are inserted into, and the bare wire head of conducting wire is protected, and prevent practical operation personnel from touching
Electricity, then intermediate throughholes seat limitation reset push rod propulsion position, ensures after being actually used for a long time, and it is inclined to reset push rod appearance or so
The case where shifting, the left right compression retaining plate spring structure of compression retaining leaf spring one is identical and installation position is symmetrical, and mainly peeling is more
Stock lead is suppressed, and increases stationarity and stability that peeling strand wire head is connect with the present invention, i.e., by peeling multiply
After lead is inserted into, the left left U-type groove for compressing retaining leaf spring end face buckles peeling strand wire head, ensures peeling multiply
Lead is steadily contacted with positive strap, provides the contact relation more stable than the prior art, left compression retaining leaf spring packet
A horizontally disposed compression retaining transverse slat and a vertical plate for being vertically arranged and offseting with intermediate throughholes seat lateral wall are included, when
It needs if extracting peeling strand wire head, then pushes down on and tear electric wire jacking block open, tear the lower end arc surface and compression of electric wire jacking block open
Retaining transverse slat contacts, and provides a downward motive force always, due to for arc surface, then tearing electric wire jacking block open and compressing retaining transverse slat
Between contact be gentle effect always, be not in the action of stage shape, while being provided with and pushing away in the upper surface for tearing electric wire jacking block open
Into slot 151, then can be applicable in external push rod act on promote slot acted, prevent maloperation, it is ensured that the safety of connection, erect
Straight panel offsets with intermediate throughholes seat, is to ensure that left compression retaining leaf spring the actual loading the case where, unitarily formed stability, if
Vertical plate is offseted with other of the invention positions, it may appear that the case where discontinuity, the medial surface for tearing electric wire jacking block open is inclined-plane
Setting, and to be inwards obliquely installed is to ensure in the case where tearing electric wire jacking block open and being pushed downward upon bottom, is not in the feelings to get stuck
Condition tears open and offsets in the middle part of the lower contact jaw and compression retaining transverse slat of electric wire jacking block, reaches the principle of lever stress, supporting rack improves
The bonding strength of leaf spring axis and breaker body.
Beneficial effects of the present invention：Connecting terminal and breaker are integrated together by the present invention, provide a kind of combined type
Breaker, while being additionally arranged left compression retaining leaf spring and right compression retaining leaf spring ensure that peeling strand wire head is being inserted into just
After polar conductor access aperture and cathode conductor access aperture, left compression retaining leaf spring and right compression retaining leaf spring can force peeling multiply
Lead offsets with connection sheet, only pushes down on left compression retaining leaf spring and right compression retaining tearing electric wire jacking block downward actuation open
When leaf spring, peeling strand wire head could be pulled out from positive wire access aperture and cathode conductor access aperture, and left compression retaining
Leaf spring and the right retaining leaf spring that compresses can prevent wire dropping equal to or more than the U-type groove of conducting wire, ensure the link of reliability
Relationship, while under for specific environment, reducing the installation space of device.
