Description

Termination

Technical field

The utility model relates to the electrical connection technical field, refers in particular to termination.

Background technology

Termination is an important electrical connection, plays a part to be fastenedly connected lead, the lead wiring closely with firm degree, directly have influence on the function of use and the life-span of electric/electronic device again.During existing termination wiring, lead is directly to be weldingly fixed on contact chip, or directly is pressed in the wire frame through the key screw power line, has that wiring is insecure, a shortcoming such as loose contact and mounting or dismounting inconvenience.

The utility model content

The purpose of the utility model be exactly the deficiency that exists to prior art and provide a kind of wiring firmly, reliable, the simple load and unload termination of lead of contact.

To achieve these goals, the technical scheme of the utility model employing is: termination includes wire frame, terminal screw; Wire frame is hollow tubular structure, and the upper surface of wire frame offers screwed hole respectively near the position of both sides, and each screwed hole is connected with terminal screw respectively; The both sides of wire frame are respectively equipped with compressing tablet; Compressing tablet is bent into " Contraband " type structure, and the top of compressing tablet extends to the screwed hole top, and its bottom extends to the screwed hole below; The end of thread of terminal screw passes the top of compressing tablet and is threaded in the screwed hole, and the bottom roof pressure of terminal screw is on the upper surface of compressing tablet bottom.

The top of said compressing tablet is a U type structure.

The bottom of said compressing tablet forms the multiple tracks striped.

The upper surface punch forming of said compressing tablet bottom has overhead kick.

Said wire frame bottom inside forms anti-skidding muscle.

The middle part, upper surface of said wire frame also offers screwed hole.

Said wire frame is to make the overlapping and square tubular structure that is pressed in rear and front end by a slice sheet metal through bending.

The utility model beneficial effect is: the termination that the utility model provides, include wire frame, terminal screw, and wire frame is hollow tubular structure; The upper surface of wire frame offers screwed hole respectively near the position of both sides, and each screwed hole is connected with terminal screw respectively, and the both sides of wire frame are respectively equipped with compressing tablet; Compressing tablet is bent into " Contraband " type structure, and the end of thread of terminal screw passes the top of compressing tablet and is threaded in the screwed hole, and the bottom roof pressure of terminal screw is on the upper surface of compressing tablet bottom; When needing wiring, turn terminal screw and drive the compressing tablet rising, lead is placed between compressing tablet bottom and the wire frame; Tighten terminal screw compressing tablet is pressed on lead in the wire frame, wiring is firm, and contact is reliable; And only need unscrew terminal screw and just can lead be removed, the lead mounting or dismounting are convenient.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described, sees shown in Fig. 1 ~ 5, the utility model includes wire frame 1, terminal screw 2; Wire frame 1 is to make the overlapping and square hollow tubular structure that is pressed in rear and front end by a slice sheet metal through bending, and the one of which end forms T type piece, and the other end offers screens; T type piece is embedded in the screens, and manufacture craft is simple, improves the structural strength of wire frame 1; Bending resistance is withstand voltage, and is not yielding.The upper surface of wire frame 1 offers screwed hole 11 respectively near the position of both sides; Screwed hole 11 is processed through back suction tooth mode, and each screwed hole 11 is connected with terminal screw 2 respectively, and the both sides of wire frame 1 are respectively equipped with compressing tablet 3; Compressing tablet 3 is bent into " Contraband " type structure; The top of compressing tablet 3 extends to screwed hole 11 tops, and its bottom extends to screwed hole 11 belows, and the top of compressing tablet 3 is a U type structure; The end of thread of terminal screw 2 passes the U type top of compressing tablet 3 and is threaded in the screwed hole 11, and the bottom roof pressure of terminal screw 2 is on the upper surface of compressing tablet 3 bottoms.Compressing tablet does not leave through not collapsing after wrapping up.

The bottom of compressing tablet 3 forms multiple tracks striped 31, and the upper surface punch forming of compressing tablet 3 bottoms has overhead kick 32, improves contact reliability and wiring steadiness between compressing tablet 3 and terminal screw 2, the lead.Wire frame 1 bottom inside forms anti-skidding muscle 12, prevents that lead from sliding, and improves contact reliability.

In addition, middle part, the upper surface of wire frame 1 also can offer screwed hole 11, can connect three lines simultaneously.

When needing wiring; Turn terminal screw 2 and drive compressing tablet 3 risings, lead is placed between compressing tablet 3 bottoms and the wire frame 1, tighten terminal screw 2 compressing tablet 3 is pressed on lead in the wire frame 1; Wiring is firm; Contact is reliable, and only need unscrew terminal screw 2 and just can lead be removed, and the lead mounting or dismounting are convenient.

The operation principle of the utility model is: through conductor compression jointing; Because both sides termination in use is identical, only narrate the structure of one of which side, insert in the wiring hole inner core termination of peeling off insulating barrier of lead; Compressing tablet 3 can move up and down with terminal screw 2 when turning terminal screw 2; Thereby compress or discharge the inner core of lead, an ancient piece of jade, round, flat and with a hole in its centre can be surrounded on the cross section causing rounded lead inner core periphery, so that better compress lead in the indent lower arcuate surface of compressing tablet 3 and the arc of screwed hole.

Certainly, the above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
