Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 8, a circuit breaker wiring device 10 includes: a housing 11. Two first terminal assembly 12, two second terminal assembly 13 and a circuit breaker assembly are mounted within the housing 11. The first and second terminal assemblies 12 and 13 are each adapted to receive an external wire for electrically connecting the external wire to the circuit breaker assembly. Two first terminal assembly 12 are mounted at one end of the housing 11, and two second terminal assembly 13 are mounted at the other end of the housing 11. Wherein the first terminal assembly 12 includes: a first wiring board 121 and a wiring terminal 14; the second terminal assembly 13 includes: a second terminal plate 131 and a terminal block 14.
As a further structure, the connection terminal 14 includes: a card housing 141 and an adjusting screw 142. The card case 141 is formed with a card slot 1411. When wiring, external wires are inserted into the card slot 1411. The card case 141 is also formed with a screw hole. The adjustment screw 142 is adjustably coupled to the card case 141 by being screwed into the screw hole. One end of first wiring board 121 is inserted into card slot 1411. After the external lead is inserted, the adjusting screw 142 is screwed into the threaded hole, and one end of the adjusting screw 142 drives one end of the first wiring board 121 to move downward until the lead is pressed on the wall of the slot 1411. At this time, the wires are press-fitted between the groove wall of the card slot 1411 and one end of the first wiring board 121.
Further, a plurality of first ribs 1211 are formed at one end of the first wiring board 121 on a side for contacting the adjustment screw 142. This arrangement can increase the mechanical strength of the first terminal plate 121, prevent it from being deformed, and improve the resistance of the first terminal plate 121 to the torque, so that the stability of the press-fitting structure between one end of the adjustment screw 142 and the first terminal plate 121 is higher. One side of one end of the first wiring board 121 for contacting the wires is formed with a plurality of first wire-pressing grooves 1212 and a plurality of first protrusions 1213. The first protrusions 1213 are uniformly distributed on both sides of the first wire pressing grooves 1212. The first wire pressing grooves 1212 can increase the friction between the wires and the groove walls when the wires are pressed, so as to more effectively and firmly limit the multi-strand wires on the groove walls. Meanwhile, the first protrusions 1213 on both sides of the first wire pressing groove 1212 firmly restrain the wire between the first protrusions 1213 on both sides, so as to limit the position of the wire, thereby preventing the wire from moving to both sides and even from being disconnected.
Also, one end of the second wiring board 131, at a side for contacting the adjustment screw 142, is formed with a plurality of second ribs 1311. This arrangement can increase the mechanical strength of the second terminal plate 131, prevent it from being deformed, and improve the torque-receiving capacity of the second terminal plate 131, so that the stability of the press-fitting structure between one end of the adjusting screw 142 and the second terminal plate 131 is higher. One side of one end of the second wiring board 131 for contacting wires is formed with a plurality of second wire-pressing grooves 1312 and a plurality of second protrusions 1313. The second protrusions 1313 are uniformly distributed on both sides of the second line-pressing grooves 1312. The second wire-pressing grooves 1312 can increase the friction between the wires and the groove wall when the wires are pressed, so that the multi-strand wires can be more effectively and firmly limited on the groove wall. Meanwhile, the second protrusions 1313 located at both sides of the second line-pressing groove 1312 firmly restrain the wire between the second protrusions 1313 at both sides, limiting the position of the wire, thereby preventing the wire from moving to both sides and even from being disconnected.
Further, the groove wall of the catching groove 1411 for contacting the wire is formed with a plurality of fitting grooves 1412 and a stopper bead 1413. Specifically, the two limiting ribs 1413 are respectively distributed on two sides of the plurality of matching grooves 1412. The plurality of matching grooves 1412 are arranged in parallel and distributed along a third straight line. The two limiting ribs 1413 are long ribs and the extending direction is parallel to the extending direction of the matching groove 1412. The cooperation of the matching groove 1412 and the limiting convex rib 1413 increases the pressure on the wire, the wire inserted into the clamping groove 1411 is better locked between the wiring board and the wiring terminal 14, and the necessary contact pressure can be kept on the wire for a long time, so that the reliability of the wiring terminal 14 for press-fitting the wire is improved, and the stability of wire connection is ensured.
In one specific embodiment, the first ribs 1211 and the second ribs 1311 are strip-shaped ribs. The contact area between the elongated rib and one end of the adjusting screw 142 is large, and the pressure per unit area of the first wiring board 121 and the second wiring board 131 can be reduced, thereby improving the overall pressure resistance. Specifically, the numbers of the first beads 1211 and the second beads 1311 are both 4.
As a specific embodiment, the first wire pressing grooves 1212 are arranged in parallel and distributed along a first straight line. The second line-pressing grooves 1312 are arranged in parallel and distributed along a second straight line.
Further, the number of the first line pressing grooves 1212 and the second line pressing grooves 1312 is 8. The number of the first protrusions 1213 and the second protrusions 1313 is 2. The two first protrusions 1213 are symmetrically arranged about the first line. The two second protrusions 1313 are symmetrically disposed about the second straight line. The structure ensures the stability of wire press fitting, and has simple structure, thus leading the processing cost to be lower.
As a particular embodiment, first protrusion 1213 and second protrusion 1313 are each wolf tooth shaped protrusions.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
