DETAILED DESCRIPTION

[0024] The following embodiments will further illustrate the present invention, but are not intended to limit the present invention.

[0025] like Figures 1 to 5As shown, a compact multi-channel connector of this embodiment includes an insulating housing 1, on which five first wiring cavities 104 and five second wiring cavities 105 are arranged in a staggered manner; the bottom surfaces of all second wiring cavities 105 have the same vertical height and are higher than the bottom surfaces of the first wiring cavities 104, so that the first wiring cavities 104 and the second wiring cavities 105 form two layers: the first wiring cavities 104 are located in the lower layer, and the second wiring cavities 105 are located in the upper layer. In the prior art, the wiring cavities are usually arranged in parallel and parallel. If the wiring cavities are arranged too closely, the cavity wall of the wiring cavity will become thinner, thereby causing a decrease in insulation resistance, which will affect the normal operation of the electrical circuit at the least, and insulation breakdown or short-circuit ablation will occur at the worst, causing safety accidents; this embodiment staggers the wiring cavities by setting two layers of wiring cavities, thereby reducing the distance between adjacent wiring cavities without reducing the thickness of the cavity wall of the wiring cavity, thereby achieving a compact arrangement effect.

[0026] A first conductor 2 is arranged in the first wiring cavity 104. A hole is arranged at one end of the first conductor 2. The axial direction of the hole is parallel to the length direction of the first wiring cavity 104, and is connected to the external wire in a tube-like manner. The two ends of the first conductor 2 are in plate-like shape, and both can be connected to the external wire in a plate-like manner. The tube-type connection and the plate-type connection are conventional technologies in this field, which are applicable to the wiring terminals of different types of wires and are widely used. Those skilled in the art should understand that they will not be described here. The different wiring methods at the two ends of the first conductor 2 are used to expand the adaptability type of the wire, so as to achieve the connection effect that the first conductor 2 is compatible with a variety of wire terminals. Screw holes 6 are provided at the two ends of the top of the first conductor 2, and screws 7 are threadedly connected in the screw holes 6. The external wires at the two ends of the first conductor 2 are electrically connected by pressing the external wires with the screws 7. A first baffle 106 is provided in the middle of the first wiring cavity 104, the first conductor 2 is located at the bottom of the first baffle 106, and the screws 7 at both ends of the first conductor 2 are higher than the bottom of the first baffle 106, so that the first conductor 2 is limited in the first wiring cavity 104 by the first baffle 106 through the screws 7 at both ends. In addition, a threading hole 102 is also provided in the insulating housing 1 at one end of the first wiring cavity 104, which is convenient for restraining the external wires and reducing the skew of the external wires.

[0027] The second conductor 3 is arranged in the second wiring cavity 105, and both ends of the second conductor 3 are plate-shaped and are connected to the external conductor in a plate-like manner. Screw holes 6 are provided at both ends of the top of the second conductor 3, and screws 7 are threadedly connected in the screw holes 6. The wires at both ends of the second conductor 3 are electrically connected by pressing the external wires with the screws 7. In this embodiment, the inner walls on both sides of the second wiring cavity 105 are provided with slide grooves, and the edges on both sides of the second conductor 3 are arranged in the slide grooves, so as to realize both the limiting function and the assembly guiding function of the second conductor 3. In addition, a second baffle 107 is arranged in the middle of the first wiring cavity 104, and the second conductor 3 is located at the bottom of the second baffle 107. The screws 7 at both ends of the second conductor 3 are higher than the bottom of the second baffle 107, so that the second conductor 3 is limited in the second wiring cavity 105 by the second baffle 107 through the screws 7 at both ends.

[0028] A spare screw hole 201 is also provided at the top of the first conductor 2 near the cylindrical end. When using the screw 7 to fasten the external wire, you can choose between the original screw hole 6 and the spare screw hole 201 to expand the scope of application. You can also use two screws 7 to connect with the screw hole 6 and the spare screw hole 201 respectively to improve the fastening.

[0029] The insulating housing 1 is provided with mounting holes 101 penetrating vertically on both sides thereof. The insulating housing 1 can be mounted on an external base surface by passing mounting screws 7 through the mounting holes 101 , thereby achieving a fixed mounting effect of the insulating housing 1 .

[0030] Furthermore, the thickness of the plate-type connecting end of the first conductor 2 is smaller than the thickness of the barrel-type connecting end of the first conductor 2 , which can reduce the amount of conductive material used.

[0031] The dust cover 4 is made of a transparent material, and a plug 401 is provided at the bottom of the dust cover 4. The plug 401 is inserted and connected with the top of the installation hole 101. After the dust cover 4 is installed, it covers the top of the first wiring cavity 104 and the second wiring cavity 105, thereby preventing the first wiring cavity 104 and the second wiring cavity 105 from falling too much dust and causing malfunction. At the same time, the transparent dust cover 4 facilitates observation of the wire connection status.

[0032] A marking groove 103 is provided on the top of the insulating housing 1 , and a marking strip 5 is clamped in the marking groove 103 . When there are multiple connectors at the same time, inserting marking strips 5 of different colors into the marking groove 103 can achieve a distinguishing effect.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
