Detailed Description

The specific structure of the quick-connect type connecting terminal in the utility model is described below with reference to the attached drawings of the specification:

a quick-connect terminal, as shown in FIGS. 1 to 6, includes a conductive plate 1, a crimping plate 2, a press bolt 3 and a terminal head 4, the conductive plate 1 is provided with a screw hole 11 which is in threaded fit with the compression bolt 3, the compression joint plate 2 is movably sleeved on the compression bolt 3 through a through hole on the compression joint plate, and is limited at the upper end of the compression bolt 3 through a limit structure, the compression plate 2 and the compression bolt 3 can rotate relatively, the connector lug 4 is connected at the end part of a lead, having flat tabs 41 thereon, the flat tabs 41 being interposed between the conductive plate 1 and the crimping plate 2, an avoiding gap 42 for avoiding the compression bolt 3 is arranged at the end part of the flat insertion piece 41, a first connecting boss 21 is arranged on the lower surface of the compression joint plate 2, the upper part of the flat insertion sheet 41 is provided with a connecting groove 43 correspondingly matched with the first connecting boss 21. Binding post in this embodiment is rational in infrastructure, when the wiring, not hard up (need not pull down) clamp bolt 3, clamp bolt 3 not hard up in-process drive clamp plate 2 upwards keeps away from current conducting plate 1, forms the space between the two, will again in the flat inserted sheet 41 of connector lug 4 inserts in the space and makes clamp bolt 3 enter into dodge breach 42, then screw up clamp bolt 3 and drive crimping board 2 and move down and compress tightly flat inserted sheet 41 in current conducting plate 1 upper surface, form the cooperation through the first connecting boss 21 on crimping board 2 and the spread groove 43 on the flat inserted sheet 41 simultaneously and strengthened being connected, avoid the connector lug pine to take off, thereby quick and reliable completion wiring operation, have fine practicality, but this binding post structure wide application is on moulded case circuit breaker, ac contactor, thermorelay electrical apparatus products etc.
