DETAILED DESCRIPTION

[0023] The following embodiments will further illustrate the present invention, but are not intended to limit the present invention.

[0024] like Figures 1 to 7 As shown, this embodiment provides an ultra-thin side-entry multi-channel connector, including a shell 1. The shell 1 in this embodiment is a semi-open flat box structure, wherein the back of the shell 1 is closed, the front of the shell 1 is open, and the other four sides of the shell 1 are narrow sides; when the shells 1 of the connectors of two embodiments are combined side by side, the closed back of one shell 1 is combined with the open front of the other shell 1, so that the other shell 1 forms a closed space; when multiple embodiments are combined, a baffle can be added to the front of the shell 1 of the outermost embodiment, so that the inside of the shell 1 of the outermost embodiment also forms a closed space to avoid exposure of components in the shell 1.

[0025] A first jack 101 is disposed on one side of the housing 1, and a second jack 102 and a third jack 103 are disposed on the other side of the housing 1. The first jack 101, the second jack 102 and the third jack 103 are used to insert three different external wires 7. The second jack 102 is above the third jack 103, the depth of the second jack 102 is less than the depth of the third jack 103, the third button slot 106 is vertically disposed at the outermost side of the top of the housing 1, and the second button slot 105 is staggered beside the third button slot 106, so as to achieve a compact staggered layout effect, thereby achieving the effect of arranging the second jack 102 and the third jack 103 up and down, thereby reducing the narrow width of the housing 1.

[0026] The interior of the shell 1 is provided with a first wiring cavity 107, a second wiring cavity 108 and a third wiring cavity 109; the end of the first jack 101 is connected to the first wiring cavity 107, the end of the second jack 102 is connected to the second wiring cavity 108, and the end of the third jack 103 is connected to the third wiring cavity 109, and the external wire 7 can be inserted into the corresponding wiring cavity through the jack.

[0027] On the top of the housing 1, a first button slot 104, a second button slot 105 and a third button slot 106 are vertically arranged; the bottom of the first button slot 104 communicates with the top of the first wiring cavity 107, the bottom of the second button slot 105 communicates with the top of the second wiring cavity 108, and the bottom of the third button slot 106 communicates with the top of the third wiring cavity 109.

[0028] A first U-shaped conductive spring 401 is arranged in the first wiring cavity 107, a second U-shaped conductive spring 402 is arranged in the second wiring cavity 108, and a third U-shaped conductive spring 403 is arranged in the third wiring cavity 109. The structures of the first U-shaped conductive spring 401, the second U-shaped conductive spring 402 and the third U-shaped conductive spring 403 are the same. At one end of the three U-shaped conductive springs 4, a chuck 404 is arranged. On both sides of the chuck 404, a pressure tongue 405 is arranged. At the other end of the U-shaped conductive spring 4, a connector 406 is arranged. The connector 406 is inserted into the socket on the conductive bar 3, so as to be electrically connected to the conductive bar 3.

[0029] A conductive cavity 110 is arranged in the housing 1. A "nai"-shaped conductive bar 3 is arranged in the conductive cavity 110. The conductive cavity 110 communicates with the first wiring cavity 107, the second wiring cavity 108 and the third wiring cavity 109. And the conductive bar 3 is connected to the connector 406 of each U-shaped conductive spring 4, so as to achieve the effect that the external wire 7 is electrically connected to each other through the U-shaped conductive spring 4 and the conductive bar 3.

[0030] A first button 201 is arranged in the first button slot 104, a second button 202 is arranged in the second button slot 105, and a third button 203 is arranged in the third button slot 106. Vertical anti-misalignment slots 114 are arranged on the inner walls of all the button slots. Anti-misalignment strips 204 are correspondingly arranged on the edges of all the buttons 2. The anti-misalignment strips 204 are slidably connected in the anti-misalignment slots 114, achieving the effect of avoiding misinstallation.

[0031] After the external wire 7 is inserted into the wiring cavity, since the outer side of the chuck 404 of the U-shaped conductive spring 4 is a slope, an inverted ratchet structure is formed, which is convenient for the external wire 7 to be inserted along the slope. After insertion, the elastic force generated by the U-shaped elastic structure of the U-shaped conductive spring 4 makes the chuck 404 clamp one end of the external wire 7, preventing the external wire 7 from being pulled out; the bottom end of the button 2 is connected to the pressure tongue 405 of the U-shaped conductive spring 4. When the button 2 is pressed, the opening of the U-shaped conductive spring 4 is pressed together through the pressure tongue 405, so that the chuck 404 is separated from one end of the external wire 7, facilitating the pulling out of the external wire 7.

[0032] The top of the housing 1 is provided with a measuring hole 112, which is connected to the first wiring chamber 107. The external measuring connector 6 is inserted and connected to the measuring hole 112, thereby being electrically connected to one end of the external wire 7 in the first wiring chamber 107 to achieve a measuring effect. In other embodiments, the measuring hole 112 may also be connected to the second wiring chamber 108 and the third wiring chamber 109.

[0033] The bottom of the housing 1 is provided with a snap-in groove 111 , which is snap-fitted with an external mounting rail for easy installation.

[0034] A marking groove 113 is respectively arranged on both sides of the housing 1 , and a marking strip 5 is respectively arranged in the marking groove 113 . The marking strip 5 is inserted into the marking groove 113 to achieve a marking recognition effect.

[0035] Wiring instructions for this embodiment:

[0036] Before use, the housing 1 of the embodiment is mounted on the guide rail through the snap-fitting groove 111 .

[0037] Insert the three external wires 7 into the first jack 101, the second jack 102 and the third jack 103 respectively, one end of the external wire 7 enters the wiring cavity through the jack and is clamped with the clamp head 404 of the U-shaped conductive spring 4, so as to fix the external wire 7; the external wire 7 is connected to the conductive strip 3 through the U-shaped conductive spring 4, so as to achieve the effect of electrical connection between the three external wires 7.

[0038] When the external wire 7 is pulled out, the button 2 is pressed, and the button 2 drives the tongue 405 to close the opening of the U-shaped conductive spring 4, thereby separating the clamping head 404 of the U-shaped conductive spring 4 from one end of the external wire 7, thereby facilitating manual pulling out of the external wire 7.

[0039] 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.
