Abstract

The utility model relates to a novel wiring terminal, which belongs to an electric inserting connector. The utility model is composed of a screw, a washer, and an elastic fall-proof washer, wherein, the washer is sheathed on the screw through the middle hole of the washer, and the elastic fall-proof washer is sheathed on the part of the screw under the washer; because the elastic fall-proof washer is fixed on the screw under the elastic force action, the washer can be prevented from falling down, when the screw is unscrewed, the washer can be elevated with the screw, and the utility model provides convenience for directly inserting conducting wires or wrapping the conducting wires. The utility model can be widely used on contactors, switches, instruments, detectors or other various electromechanical products.

Description

Wiring terminal

The utility model belongs to a kind of electronic connector, relates in particular to a kind of novel connecting terminal.

At present, common binding post commonly used generally is made of screw and packing ring, have circular hole in the middle of the packing ring, be enclosed within on the screw, lead is positioned under the packing ring during wiring, by turning screw lead is pressed under the packing ring, the shortcoming that this common binding post exists is: (1) when needs earlier with lead behind the screw bottom, when tightening screw again, because the packing ring that is enclosed within on the screw is again little and thin, very easily drop, brought inconvenience to wiring; (2) lead does not need on screw in some cases, only need screw is unscrewed, lead is inserted under the packing ring, tighten screw again and get final product, but use common binding post, when unscrewing screw, cover packing ring does not thereon rise with screw owing to action of gravity, lead is not easy to insert under the packing ring very much, needs to assist with other instrument, has influenced wiring speed.

The purpose of this utility model provides a kind of novel connecting terminal, and the back-out when packing ring can be unscrewed with bolt is risen, and gasket sleeve can not drop on screw, for wiring is provided convenience.

A kind of novel connecting terminal that the utility model is designed, mainly comprise screw and packing ring, have circular hole in the middle of the packing ring, be enclosed within on the screw, it also comprises the anti-fall packing ring of an elasticity, the anti-fall gasket sleeve of elasticity is on the screw under the packing ring, and the internal diameter of the anti-fall packing ring of elasticity is less than the external diameter of screw, and its thickness is greater than the hole of packing ring and the gap between the screw.

The anti-fall packing ring of the elasticity of this novel connecting terminal is made by materials such as plastics or rubber.

In addition, the screw in this novel connecting terminal can be various forms of screws such as round end, turret head, cross, yi word pattern, and packing ring also can be the packing ring of different shapes such as rounded washers, square washer, plain washer, saddle shaped washer.

The advantage of the novel connecting terminal that the utility model is designed is:

(1) owing to the flexible anti-fall packing ring of trapping at packing ring, the anti-fall packing ring of elasticity is fixed on the screw under the elastic force effect, again since the thickness of the anti-fall packing ring of elasticity greater than the hole of packing ring and the gap between the screw, therefore when packing ring falls under action of gravity, be subjected to not stopping of the anti-fall packing ring of elasticity can drop out; When unscrewing screw, rise with screw because of the anti-fall packing ring of elasticity again; Make the packing ring that drops on the anti-fall packing ring of elasticity also rise together, thereby lead is very easily inserted under the packing ring, for wiring provides convenience.

(2) the anti-fall packing ring of the elasticity of this novel connecting terminal is to make with materials such as plastics or rubber, so the cost of binding post do not have too many increase, and the speed of wiring is greatly accelerated.

In addition, the designed novel connecting terminal of the utility model can be widely used in instrument, instrument, switch, contactor and other electronic product.

Fig. 1 is the schematic diagram of the designed novel connecting terminal of the utility model.

Fig. 2 is a binding post shown in Figure 1 cutaway view when using.

Fig. 3 is a binding post shown in Figure 1 schematic diagram when unscrewing.

Below in conjunction with specific embodiment execution mode of the present utility model and effect are described further.

Embodiment

Fig. 1,2, the 3rd, the structure chart of a kind of novel connecting terminal that the utility model is designed.It mainly comprises screw 1 and saddle shaped washer 2, also comprise an anti-fall packing ring of making by elastomeric material 3 of elasticity, saddle shaped washer 2 is enclosed within on the screw 1 by the hole on it 5, the flexible anti-fall packing ring 3 of cover on the screw of saddle shaped washer 2 bottoms, the internal diameter of the anti-fall packing ring 3 of elasticity is littler 1 millimeter than the external diameter of screw 1, the thickness of the anti-fall packing ring 3 of elasticity is bigger 1 millimeter than the gap between the external diameter of the internal diameter in the hole 5 of saddle shaped washer 2 and screw 1, the anti-fall packing ring 3 of elasticity can not drop owing to the elastic force effect is fixed on the screw 1, and being subjected to stopping of the anti-fall packing ring 3 of elasticity, saddle shaped washer 2 in the top also can not drop, when wiring, can be with the bottom (as Fig. 1) of lead 4 around screw 1, then screw 1 is tightened on the workpiece 6, lead 4 is pressed in saddle shaped washer 2 times (as Fig. 2), if lead does not need on bolt 1, in the time of can directly inserting saddle shaped washer 2 times, then only need unscrew screw 1, because the anti-fall packing ring 3 of elasticity is fixed on the screw 1 because of elastic force, therefore the anti-fall packing ring 3 of elasticity rises with bolt 1, saddle shaped washer 2 is owing to the anti-fall packing ring 3 of pad property stops also along with rise together (as Fig. 3), insertion formation gap for lead, make lead can directly insert arc packing ring 2 times, and then tighten screw 1 lead is pressed on saddle shaped washer 2 times.

Can be found out that by the above embodiments very convenient when this novel connecting terminal uses, the packing ring that has overcome on the common binding post is in the past easily lost, lead is difficult for inserting the shortcoming under the packing ring during wiring, has accelerated wiring speed.

Claims

1, a kind of novel connecting terminal, mainly comprise screw, packing ring, packing ring passes through middle borehole jack on screw, it is characterized in that: on the screw of packing ring bottom, also be with the anti-fall packing ring of an elasticity, the internal diameter of the anti-fall packing ring of elasticity is less than the screw external diameter, and the thickness of the anti-fall packing ring of elasticity is greater than hole in the middle of the packing ring and the gap between the screw.

2,, it is characterized in that the anti-fall packing ring of elasticity made by plastics or elastomeric material according to the said novel connecting terminal of claim 1.
