Description

a quick connector

technical field

The utility model relates to a power supply connection joint, in particular to a puncture quick joint applied to low-voltage garden lamps and park lawn lamps.

Background technique

At present, with the improvement of people's living standards, low-voltage garden lights and park lawn lights are becoming more and more popular, and the demand for such lights in the market is also increasing. Puncture quick connectors are becoming more and more important as connection accessories for low-voltage garden lights and park lawn lights, and are more and more popular in the market. There are many kinds of power cords for low-voltage garden lights and park lawn lights, such as SPT-1 series: 18AWG, 16AWG, 14AWG, and SPT-2 series: 18AWG, 16AWG, 14AWG, etc., plus SPT-3 series , SPT-1W series, SPT-2W series, there are more than a dozen kinds. Since the quick connectors on the market are designed for a single power cord, the types of piercing quick connectors also change with the type of power cord. It is extremely inconvenient for people to purchase puncture quick connectors, and the puncture connectors on the market are either designed as one, or designed so that they are not easy to disassemble, inconvenient to repair and replace, and if they are broken, they can only buy new ones, resulting in unnecessary waste.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a piercing quick connector which can be used for various power cords.

The technical scheme that the utility model solves its technical problem adopts is:

A quick joint is characterized in that it includes a joint main body, the main body is cylindrical, two open slots are arranged on the side wall of the main body, the bottom of the open slot is a wiring hole with a wide top and a narrow bottom, and the outer side wall of the upper part of the main body and the inner side wall of the lower part are provided with threads; an adjusting screw, which is threadedly connected with the lower part of the joint body, and its top can be screwed up to the upper part of the wiring hole; a slider, which is installed in the joint body, and the slider is installed with A connection terminal and a barbed copper sheet; a nut, which is threadedly connected with the upper part of the joint main body, and a pressure rod that can be inserted into the joint main body and press the slider is arranged in the nut.

As an improvement of the above-mentioned technical solution of the utility model, several groups of slide grooves are relatively provided on the inner side wall of the upper part of the joint body, and the side walls of the slider are provided with slide bars that can be inserted into the slide grooves.

The above two open slots can be arranged opposite to each other.

The beneficial effects of the utility model are: the utility model can be adapted to power cords of different specifications such as 18AWG, 16AWG, 14AWG of the SPT-1 series and 18AWG, 16AWG, 14AWG of the SPT-2 series by adjusting the adjusting screw and the slider , thereby increasing its application range; all parts can be disassembled, easy to repair and replace, and can be reused for a long time, thus preventing unnecessary waste.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a schematic diagram of the decomposition structure of the utility model;

Fig. 2 is the front view of slider;

Fig. 3 is a top view of the joint body.

Detailed ways

Referring to Fig. 1 and Fig. 2, a quick connector disclosed by the utility model includes a connector main body 1, the main body 1 is cylindrical, and two opening grooves 2 are arranged on the side wall of the main body 1, and the two opening grooves 2 can be opposite to each other. It can also be staggered by a certain angle. The bottom of the opening groove 2 is a wiring hole 3 with a wide top and a narrow bottom. The widths of the various parts of the wiring hole 3 correspond to the widths of power cords of different specifications. An internal thread 5 is provided.

An adjusting screw 6 is threadedly connected to the lower part of the joint main body 1 , and the top of the adjusting screw 6 can be screwed up to the upper part of the wiring hole 3 .

There is a slider 7 installed in the main body 1 of the connector, and a terminal 8 and a barbed copper piece 9 are installed on the slider 7. The terminal 8 is used to connect with the wires of low-voltage garden lights and park lawn lights, and the barbed copper piece 9 can pierce the power supply. The wire is insulated and electrically coupled to the conductors of the power cord.

A nut 10 is threadedly connected to the upper part of the connector main body 1, and a pressing rod 11 that can be inserted into the connector main body 1 and press the slider 7 is arranged in the nut 10, so as to fix the power cord.

Referring to Fig. 3, several groups of chute 12 are relatively arranged on the inner side wall of the upper part of the joint body 1, and the side wall of the slider 7 is provided with a sliding bar 13 that can be inserted into the chute 12, and each group of chute corresponds to a specification power cord. During the assembly process, for power cords of different specifications, the sliding bar on the slider is inserted into the chute corresponding to the power cord to ensure that the barbed copper sheet has a good electrical connection with the inner core of the power cord after piercing the power cord .

When using power cords with different sizes and specifications, the power cords are respectively stuck on the two side walls of the wiring hole, and the adjusting screw is adjusted to make the upper part contact with the bottom of the power cord, and at the same time, insert the slide bar of the slider into the same position as the power cord. Corresponding chute, slide the slider into the main body of the connector, tighten the nut, make the barbed copper sheet pierce the insulation sheath of the power cord and electrically connect with the wind core of the power cord to complete the connection between the connector and the power cord.
