When the wiring is required to be connected in the wiring terminal, an external tool is utilized to apply downward force to the clamping elastic sheet in a direct or indirect mode, the free end part of the clamping elastic sheet is elastically deformed after being stressed to move downwards, then the wire penetrates through the wiring hole of the insulating shell, the wire penetrates through a gap which is formed by the downward movement of the clamping elastic sheet and is positioned between the free end part of the clamping elastic sheet and the electric conductor, after the downward force applied to the clamping elastic sheet is relieved, the clamping elastic sheet moves upwards under the action of the elastic restoring force of the clamping elastic sheet, and the electric conductor is clamped, so that the electric contact between the electric conductor and the electric conductor is realized.
Chinese patent CN100442600C discloses a connecting device for electrical conductors, which has a clamping portion, at which a clamping spring is arranged, which is enclosed in an insulating material housing directly or via a metal holder, the clamping spring being designed to press a conductor against a contact rail in the connected state, wherein the clamping spring is provided with an operating device designed to operate a push-out piece for operating the clamping spring to open the clamping portion, characterized in that: the operating ejector is provided on its outer surface with at least two mating areas for mating with an operating tool, the two mating areas being designed for mating with a notched groove of a screwdriver, the mating areas being arranged at an angle to each other on the operating ejector, the two notched grooves being arranged at an angle of 60-120 ° to each other on the operating ejector. The provision of the actuating push-out piece in a rotatable manner makes it particularly suitable for the actuation of a direct plug connection in a narrow position, since the actuating tool can be coupled to the actuating push-out piece in different positions and different directions in order to open the clamping spring, so that the actuating push-out piece is particularly suitable for opening the spring which acts as a compression spring on the conductor and presses it against a contact rail at the clamping point, in particular in the region of the actuating push-out piece in which the two coupling areas for the actuating tool are angled relative to one another and/or in the region of the actuating push-out piece in which they are angled relative to one another.
However, the connection device disclosed in patent CN100442600C also has some problems: in the insulating material casing with limited inner space, because the operation ejector and the clamping spring are arranged on the same side of the insulating material casing, when the operation ejector ejects the free end part of the clamping spring so as to facilitate the lead to be connected into the insulating material casing or to be taken out from the insulating material casing, the operation ejector is required to have enough length so as to ensure that the operation ejector can eject the free end part of the clamping spring. Obviously, the operation ejector at this time needs to occupy a larger space in the insulating material housing, which reduces the space utilization rate in the insulating material housing, and finally, the actual need of the operation ejector for ejecting the clamping spring can be met only by increasing the whole volume of the insulating material housing.
