Abstract

A peep hole type copper terminal belongs to the technical field of electric fittings and solves the technical problem that connecting quality is affected due to the fact that inside conditions of a copper terminal in the prior art cannot be observed since a bevel face is sealed. The peep hole type copper terminal comprises a flat end, a transition section and a connecting end, a bevel face is formed on the transition section, a peep hole is formed on the bevel face, and an included angle ranging from 20 degrees to 35 degrees is formed between the bevel face and a perpendicular line of the flat end. According to the above structure, inside conditions of the terminal are easy to observe during connection, and thereby whether a lead is inserted to the bottom of the terminal or not can be accurately confirmed and connecting quality is guaranteed.

Description

Peep hole type copper wiring terminal

Technical Field

The utility model belongs to the technical field of the electric power fitting, concretely relates to copper binding post.

Background

It is known to connect a wire to a device or other connector at the end of the wire for continued power transmission, typically using a terminal.

In the prior art, a copper terminal is a commonly used terminal, and the structure of the copper terminal is shown in fig. 1, and the copper terminal comprises a flat plate end, a transition section and a terminal end, wherein the transition section is formed with a slope. When the copper wiring terminal with the structure is used for wiring, a copper conductor is required to be inserted into a wiring pipe of the wiring terminal, and then the copper conductor is crimped in a hydraulic or detonation mode.

In the wiring process, as the slope surface is of a closed structure, the condition inside the wiring terminal cannot be observed in the process of inserting the lead into the wiring terminal, so that the insertion state of the lead can be determined only by feeling, and whether the lead is inserted into the preset insertion position of the wiring terminal cannot be accurately determined. If the wire is not inserted into the predetermined insertion position of the terminal, the crimping step is performed, which may possibly cause a pseudo-crimp, and the wire is easily separated from the copper terminal after being stressed, thus undoubtedly affecting the quality of the connection.

Disclosure of Invention

Therefore, the utility model aims to solve the technical problem that copper binding post among the prior art influences the technical problem of wiring quality because domatic sealing can't observe the inside condition of wiring end to a shaping that can guarantee the wiring quality has the peephole type copper binding post of peephole is provided.

In order to solve the technical problem, the utility model discloses a technical scheme as follows:

a peephole type copper wiring terminal comprises a flat plate end, a transition section and a wiring end, wherein a slope is formed on the transition section, a peephole is formed in the slope, and an included angle alpha between the slope and a vertical line of the flat plate end is 20-35 degrees.

The angle alpha is 30 deg.

And a horn mouth is arranged at the end opening of the wiring end.

And a connecting hole is arranged through the flat plate end.

The connecting hole is a round hole.

Compared with the prior art, the technical scheme of the utility model have following profitable technological effect:

(1) peep the caliber copper binding post, set up domatic with the contained angle alpha between the perpendicular line of dull and stereotyped end is 20-35, compares with prior art, through the setting of above-mentioned angle, has guaranteed to observe the in-process of the wiring end internal conditions has the visual angle of the interior length of observation wire insertion wiring end of an ideal, has guaranteed again simultaneously that the appearance of product is pleasing to the eye. To the setting of this angle, can not be too big, too big then the visual angle is unsatisfactory is difficult to observe the inside condition of wiring end, this angle also can not be too little, too little then can influence the utility model discloses the pleasing to the eye of product.

(2) Peep hole type copper binding post, domatic last shaping has the peephole, compares prior art set up the peephole on domatic, conveniently observe when the wiring the inside condition of wiring end to whether can accurately confirm the wire and insert predetermined inserted position in the wiring end has guaranteed the quality of wiring. In addition, the peephole enables air at the position to be smooth, and the temperature at the position cannot rise too fast in the subsequent power transmission process, so that the wiring terminal is protected.

(3) Peep hole type copper binding post, wiring end port department is provided with the horn mouth. Prior art copper wire terminals are difficult to handle when inserting such wires into the terminals in the event that the wire ends are splayed apart. Compared with the prior art, peep hole type copper binding post is owing to set up the horn mouth, has just so increased the area of wiring end port for the wire inserts easily wiring end.

Drawings

In order that the invention may be more clearly understood, embodiments of the invention will now be described in further detail with reference to the accompanying drawings. Wherein,

FIG. 1 is a cross-sectional view of a prior art copper terminal;

fig. 2 is a side view cross-sectional structure diagram of the peep hole type copper wiring terminal of the present invention;

fig. 3 is a front view of the peep hole type copper wiring terminal of the present invention;

the reference numbers in the figures denote: 1-flat plate end, 2-transition section, 3-wiring end, 4-slope, 5-peephole, 6-vertical line, 7-bell mouth and 8-connecting hole.

Detailed Description

As shown in fig. 2, the copper wiring terminal of the present invention includes a flat end 1, a transition section 2 and a wiring end 3, wherein the transition section 2 is used for transitionally connecting the flat end 1 and the wiring end 3; wherein the terminal 3 is a junction tube; the last shaping of changeover portion 2 has a domatic 4, the shaping has peephole 5 on domatic 4, passes through like this when the wiring peephole 5 conveniently observes the inside condition of wiring end 3 to can accurately confirm whether the wire inserts the bottom of wiring end 3 has guaranteed the quality of wiring. In addition, the peep hole 5 enables air at the position to be smoothly circulated, and the temperature at the position cannot be too fast during subsequent power transmission, so that the wiring terminal is protected.

Wherein, the included angle alpha between the slope surface and the vertical line 6 of the flat plate end 1 is 20-35 degrees. Through the arrangement of the angles, an ideal visual angle is ensured in the process of observing the internal condition of the wiring terminal 3, and meanwhile, the attractive appearance of the product is ensured. To the setting of this angle, can not be too big, thereby too big then the visual angle is unsatisfactory is difficult to observe the inside condition of wiring end 3 also can not be too little, then too little can influence the utility model discloses the pleasing to the eye of product.

Preferably, the angle α between the slope 4 and the vertical 6 of the flat end 1 is set to 30 °.

As a preferred implementation manner, in this embodiment, in addition to the keyhole-type copper wire connecting terminal described in the above embodiment, a flared opening 7 is further provided at the port of the terminal 3. The wiring end 3 of the prior art copper wiring terminal is in a straight tube shape, and for the case that the end of the wire is scattered and bunched, the prior art copper wiring terminal causes difficulty in the process of inserting the wire into the wiring end 3. Compared with the prior art, peep hole type copper binding post is owing to set up horn mouth 7, has just so increased the area of 3 ports of wiring end for the wire inserts easily wiring end 3.
