The present invention relates to a kind of connecting terminal block, it is applied to realize electricity in the industries such as refrigeration, machinery, illumination, electric power, traffic Gas connection.

Background technique

Connecting terminal is the electronic product accessory for realizing electrical connection, and in the prior art, connecting terminal block is generally adopted With the conductive sheet of screw and base aperture cooperation link terminal, by screw tightening or control route on off operating mode, spiral shell are unclamped Silk is easy to fall off loss after unclamping, conductive sheet is also easy sliding transfer after unclamping, needs to relocate when being again switched on circuit, and mend The screw for filling loss, installs and uses inconvenience；And the patent of invention of Patent No. 201420006281.7 provides a kind of modified Electric connector increases dielectric cover in gap between top plate and lateral partitions upper end, is limited by the fixed part of dielectric cover Position wiring lock screw has a disadvantage in that, need to increase the structures such as slot, lid, amount of parts is more, and structure is complicated, conductive sheet pine Also the problem of not solution of sliding transfer is easy after opening, and erroneous for installation, combination assembly efficiency is low, and technique is inconvenient.

Summary of the invention

The technical problem to be solved by the invention is to provide a kind of connecting terminal block, can prevent screw fall off loss and Structure is simple, and amount of parts is few, easy for installation, and combination assembly efficiency is high, and technique simplifies, while conductive sheet can also be prevented loose Open rear sliding transfer.

Connecting terminal block of the invention, includes insulating base frame, and insulating base frame is divided into the power supply of front side by lateral partitions The load-side of side and rear side is divided into several jack-plug sockets by several longitudinal baffles, it is characterised in that: on front side of each jack-plug socket Opening is provided with a pair of of restriction protrusion, and adjacent pair longitudinal baffle surrounds vertical with lateral partitions front surface and a pair of of restriction protrusion Straight screw member insertion hole, wiring lock screw penetrate screw member insertion hole from top to bottom；Each screw member insertion hole bottom be mounted with The nut and conductive sheet of wiring lock screw cooperation, and for guide groove that conductive sheet is horizontally inserted into；Each screw member insertion hole is horizontal Elastic buckle is provided on partition, in Elastic buckle lateral partitions in hollow-out part, lower end is linked together with lateral partitions, on End is free end, and there is guiding surface to form the elastic hook to inner process；

Further, the restriction protrusion of screw member insertion hole has and elastic hook phase where each wiring lock screw Pair guiding surface formed fixed hook；

Further, in the lateral partitions be located at each chamber in the middle part of be provided with conductive sheet tail dimension be adapted Through-hole, conductive sheet trailing wire can pass through through-hole from power supply side cavity and enter load side cavity；

Further, the conductive sheet front end has rectangular conductive contact surface, and rectangular conductive contact surface front end two corners are upward Wing acts the wedge angle for forming protrusion, is inserted into gap formation for conductive sheet between restriction protrusion lower end and screw member insertion hole bottom surface Guide groove, guide groove gap size are slightly less than the height of conductive sheet wedge angle, so that the wedge angle is caught in guiding when conductive sheet insertion It is fixed in slot.

Connecting terminal block of the invention, wiring lock screw can enter along elastic hook and the guiding surface of restriction protrusion Insulating base frame is fixedly connected with conductive sheet, the gasket formation three of elastic hook and restriction protrusion butted line lock screw with nut cooperation Point limit, wiring lock screw will not skid off after unclamping to fall off, and it is prominent that the wedge angle that conductive sheet insertion limiting slot hind wing rises is caught in limit It plays root and forms incarceration, conductive sheet will not loosen displacement after wiring lock screw unclamps, without in addition increasing components, installation Convenient, combination assembly efficiency is high, and technique simplifies, and user is simple and convenient for reusing after equipment connection.

Specific embodiment

As shown, a kind of connecting terminal block, includes insulating base frame 1, before insulating base frame 1 is divided by lateral partitions 5 The source side of side and the load-side of rear side；Several jack-plug sockets are divided by several longitudinal baffles 2, it is characterised in that: Mei Gejie A pair of of restriction protrusion 3, adjacent pair longitudinal baffle 2 and 5 front surface of lateral partitions and a pair are provided at line jack front openings Restriction protrusion 3 surrounds vertical screw member insertion hole, and wiring lock screw 11 penetrates screw member insertion hole from top to bottom；Each screw is inserted Enter hole bottom and be mounted with the nut and conductive sheet cooperated with wiring lock screw 11, and for guiding that conductive sheet is horizontally inserted into Slot；Elastic buckle 4 is provided in each screw member insertion hole lateral partitions 5, in 4 lateral partitions 5 of Elastic buckle in hollow-out part, under End is linked together with lateral partitions 5, and upper end is free end, and there is guiding surface to form the elastic hook to inner process；When connecing When line lock screw 11 penetrates screw member insertion hole from top to bottom, the gasket of wiring lock screw 11 can be squeezed by guiding surface Elastic buckle 4 opens, so that wiring lock screw 11 is able to enter screw member insertion hole, wiring lock screw 11 enters screw and is inserted into Kong Hou, Elastic buckle reset, hook 11 gasket of butted line lock screw limit, so that wiring lock screw 11 can not exit screw It is inserted into hole.

Further, the restriction protrusion 3 of the 11 place screw member insertion hole of each wiring lock screw has hangs with elasticity The opposite guiding surface of hook forms fixed hook；Wiring lock screw 11 can be along the guiding surface of elastic hook and fixed hook Into screw member insertion hole, the gasket of elastic hook and fixed hook butted line lock screw 11 forms 3 points of limits, wiring locking Screw 11 will not skid off after unclamping to fall off；

Further, it is located to be provided in the middle part of each chamber in the lateral partitions 5 and is adapted with 7 tail dimension of conductive sheet Through-hole, 7 trailing wire of conductive sheet can from power supply side cavity pass through through-hole enter load side cavity.7 front end of conductive sheet With rectangular conductive contact surface, rectangular conductive contact surface front end two corners rise to upper fin and form raised wedge angle 9, under restriction protrusion 3 The guide groove being inserted into for conductive sheet 7 is formed between end and screw member insertion hole bottom surface with gap, guide groove gap size is slightly less than The height of 7 wedge angle of conductive sheet, so that the wedge angle is caught in guide groove and is fixed when conductive sheet 7 is inserted into.

To adapt to such 7 feature structure of conductive sheet, connecting terminal block installation method of the invention uses and conventional method Opposite approach, i.e. conductive sheet 7 pass through the through-hole in lateral partitions 5 from power supply side cavity and enter with load side cavity and equipment Installation, is caught in 3 root of restriction protrusion convenient for the wedge angle 9 of conductive sheet 7；Using such mounting means, after conductive sheet 7 is inserted into limiting slot The wedge angle 9 that wing rises is caught in 3 root of restriction protrusion and forms incarceration, and conductive sheet will not loosen position after wiring lock screw 11 unclamps It moves, can reliably guarantee that screw, conductive sheet will not be lost without in addition increasing components.
