Abstract

The utility model relates to a direct-insert wire connecting terminal, which is suitable for the connection among conducting wires and electrical equipment. The direct-insert wire connecting terminal has the characteristics of easy installation and simple operation, and is suitable for being applied in various vibration occasions. The direct-insert wire connecting terminal is composed of screws, a washer, a spring cushion and a conducting strip. The utility model is characterized in that the combining portion of the screw cap of the screw 1 and a screw rod along the radial direction of the screw is provided with a hole; the part that the hole passing through on the screw cap forms a concave groove; the conducting strip 2 sheathed on the screw runs through the surface corresponding to the screw cap; the circle center of the sheathed hole of the conducting strip has a concave groove which is the same to the screw cap.

Description

Direct-insert terminal

The utility model relates to a kind of lead is connected usefulness with electric equipment binding post, and many terminal combination are constituted terminal board together, and this terminal board is specially adapted to the connection of equipment such as various switch cubicles, protection screen between inside and outside.

Existing binding post is continued to use Vintage Product decades ago always, and this binding post is made up of screw, packing ring, spring pad, conducting strip.The assembling process of lead and binding post is wire head to be surrounded line nose (circle) pull down three on screw, packing ring, spring pad, and spring pad, packing ring, line nose through on the screw, are screwed in screw in the screw hole of conducting strip and screw.The whole operation process is loaded down with trivial details, and often is subjected to the work on the spot condition restriction, if careless slightly be difficult to once assembled successfully, it is time-consuming to install Fei Gong.Also has a kind of binding post, form by holding screw and conducting strip, conducting strip is that the tubular body wire head of square-outside and round-inside can directly insert in the hole of tubular body, press together wire head and conducting strip fixing with screw, very little the reaching of effective contact area of this binding post and conducting strip easily caused loose contact, if repeatedly the dismounting lead also can damage wires, until being become, lead falls short of, since the structures shape of this terminal it can not the mounting spring pad and prevent that loosening device is not suitable for using under the vibration occasion, functional reliability is relatively poor.

The utility model purpose is exactly a kind of binding post that overcomes above deficiency of design, and not only fitting operation is convenient for it, and suitable where the vibration under the occasion used.

The utility model purpose can reach by following measure: screw rod and nut binding site at screw radially have a hole along screw, nut is passed through in the cross section 1/3rd in hole, and cross section of formation is arc groove on nut, the also corresponding work of conducting strip one cross section that is enclosed within on the screw is arc groove, conducting strip can make tubular body as required, cuboid, multiple shape such as semicylinder, wire head is inserted in the screw hole along the nut groove, reeded that face of conducting strip that is enclosed within on the screw is pressed on the lead, two grooves can be circular-arc wire head is clipped in the middle and coincide mutually, overlap upper gasket again, spring pad, nut screws nut lead is embraced tightly by two grooves up and down.Each part can be with there being certain mechanical strength electric conductivity good metal to constitute.

The drawing of accompanying drawing is described as follows:

Fig. 1 is direct insertion binding post schematic diagram.

Fig. 2 is test voltage connection terminal structure figure.This figure only draws half so that AA axis symmetry is existing.

Fig. 3 is test current connection terminal structure figure.This figure only draws half so that AA axis symmetry is existing.

Be described in further detail below in conjunction with embodiment:

Test voltage terminal embodiment (Fig. 2)

This terminal voltage screw 1 is a tee shape, the nut of voltage screw can be semicylinder, nut and screw rod binding site and screw rod radially have a hole, the hole sectional area 1/3rd on the plane of nut semicylinder, and vertically to form a sectional area along nut be bow-shaped recess, voltage conduction rack 2 is a tubular body, and radially make letter e shape groove at tubular body, make the voltage conduction rack be enclosed within on the voltage screw, the hole of voltage screw is identical with the hole size direction of voltage conduction rack, and the nut of voltage screw is just in time down in E shape groove.Voltage nut 5,8 can be standard component also can make the cap shape that one side blocks, and the dismounting groove is arranged at the top of cap; Screw 6 in parallel has the screw that spiral shell is fixed a washer-shaped annulus between smashing for screw rod; Assembling process is that the voltage conduction rack is enclosed within on the voltage screw, and put large washer 3, big spring pad 4, screw on the voltage nut, there is the screw corresponding with screw in parallel voltage conduction rack middle part, and screw in parallel is fixed on it, put the big spring pad and screw on nut, the connection of lead is to insert wire head 9 in the end of voltage conduction rack, screws nut, and the deep-slotted chip breaker of voltage screw and voltage conduction rack resembles pliers wire head is tightly embraced.Because spring pad is arranged, also be difficult for becoming flexible at vibration occasion lower wire head, and whole contact-making surface very very much not can produce poor electric contact.

Test current terminal embodiment (Fig. 3)

This test current terminal is identical substantially with the test voltage terminal structure, just screw in the terminal screw 7 that experiment usefulness is arranged at the top of electric current screw, series connection screw 10 is fixed a packing ring sample annulus for the standard screw shape in Lower Half, the spiral shell button is arranged below the annulus, Control current in flakes 12 deciliter, electric current can make cuboid in flakes.

General terminal embodiment

The test voltage terminal is removed screw in parallel just can be used as general terminal, another kind is screw to be put side by side be fixed as one, determine the screw number as required, the conducting strip that is enclosed within on the screw can be cuboid, it is bow-shaped recess that corresponding that face of cap nut has the cross section, with the groove that cooperating between conducting strip and the screw keeps conducting strip and the groove keeping parallelism of screw.

Claims

1, a kind of lead is connected the binding post of usefulness with electric equipment, it is made up of screw, packing ring, spring pad, conducting strip, it is characterized in that radially there is a hole at the nut of screw 1 and the binding site place of screw rod along screw, make on the nut in the hole and form groove, be enclosed within the corresponding surface of conducting strip 2 and nut on the screw and pass the center of circle of conducting strip trepanning a groove identical with nut is arranged by part.

2, by the described binding post of claim 1, it is characterized in that screw 1 makes tee shape, and along the vertical pore-forming of nut, forming sectional area is arc groove, it is arc groove that conducting strip 2 also has long-pending with the nut same cross-sectional.
