Constriction sleeve 201 is flexibly connected, with a recess 20la being provided on the side surface of the constriction sleeve 201, and the adapter element 200 in the

End recess 102 is introduced.

In the present embodiment, a cable adapter device that can be installed and used in a narrow space is provided. It should be noted that in order to maintain the neatness of wiring the cables in a control box 300 the

The side surface and the bottom side of the existing control box 300 have increased thickness and are hollow. A recess is formed on the inner wall so that a wire can pass through the hollow side surface and is used to lead out a cable head

Wiring the cable is led out through the recess and connected.

It should be noted that in the control box 300, a snap plate 301 to which an electrical element or the junction box 100 is fixed is provided to facilitate wiring.

In the present invention, the junction box 100 is designed as a three socket structure

Holes are formed, which can be used for an indirect connection for a three-pin plug.

In detail, the three-pin plug is inserted into the cable entry hole 101 on the junction box 100. Due to the electrical connection between the cable insertion hole 101 and the

End recess 102, the adapter element 200 connected to the end recess 102 is electrically connected to the three-pin plug via the cable.

An end recess 102 is provided at one end region of the connection box 100

Number corresponds to the number of cable entry holes 101. For example, in the present embodiment, the cable entry hole 101 is provided in number of three, and accordingly, at the upper end of the junction box 100, there is one

End recess 102 provided with a ground wire connection hole of the

Cable entry hole 101 is electrically connected, while the lower end of the connection box 100 is provided with two end recesses 102, each with a neutral conductor

Fixing the lead wire L in the adapter element 200.

Furthermore, it is provided that the second hold-down strip 203b and the first hold-down strip 202b are arranged offset from one another and the first hold-down strip 202b lies closer than the second hold-down strip 203b to the end section of the first end head 202, so that the second hold-down strip 203b presses the insulating layer L1 and over the first 6

Y20P63LU-YUV003LU 04/26/2023

Hold-down strip 202b is moved out when after inserting an end section of the LU103109

Cable L in the first clamping groove 202a and the second clamping groove 203a, the second end head 203 is closed by turning. Without the influence of an external force, the second can

Hold-down strip 203b can hardly be moved independently beyond the first hold-down strip 202b, thereby maintaining the state in which the first end head 202 and the second end head 203 clamp and fix the end portion of the lead wire.

Furthermore, it is provided that an end section of the connection box 100 on one side with a

Plug-in groove 103 is provided, which is connected to the end recess 102; wherein the side wall of the plug-in groove 103 is provided with an oblique groove 103a which is arranged obliquely, wherein a

End portion of the oblique groove 103a is provided on one side with a round groove 103b.

It should be noted that the end recess 102 is formed by an end portion of the

Terminal box 100 is designed inwards, while the plug-in groove 103 is formed by one

Side surface of the connection box 100 is formed and connected to the end recess 102. In detail, the end recess 102 and the plug-in groove 103 form an L-shape.

Furthermore, it is provided that an end section of the oblique groove 103a extends into the end recess 102. That is, the round groove 103b is located on the side wall of the end recess 102. The oblique arrangement of the oblique groove 103a ensures that the round groove 103b can be located in the end recess 102 at a position deeper than the plug-in groove 103.

Furthermore, it is provided that the first end head 202 is provided on both sides with a lateral shaft 202c, which is embedded in the oblique groove 103a. The size of the side shaft 202c is matched to the size of the oblique groove 103a, so that the side shaft 202c can move in the oblique groove 103a.

Furthermore, it is provided that in the lowest region of the end recess 102 an electrically conductive plate 104 is arranged obliquely, which is connected at one end to the side wall of the

End recess 102 is connected, with a first spring 105 being provided in the lowest region of the end recess 102, which is connected to the electrically conductive plate 104; The

Side wall of the end recess 102 is provided with a square groove 102a provided with a push rod 102b connected at an end portion to the lowermost portion of the square groove 102a via a second spring 102c; An end section of the

Push rod 102b is provided with a push plate 102d.

Note that the electrically conductive plate 104 is inclined toward a side on which the push rod 102b is located, and the electrically conductive plate 104 is off

Y20P63LU-YUVO003LU 04/26/2023 one end is connected to the cable entry hole 101 and at the other end is connected to the electrically LU103109 conductive plate 104, thereby establishing an electrical connection.

The square groove 102a is arranged deeper than the round groove 103b and is at the opening of the

A limiting piece 102e is provided in the end recess 102. The limiting piece 102e is arranged on the side on which the push plate 102d is located and serves to

Limiting the angle of inclination of the cable L:

Below is the way to connect the adapter element 200 to the

Connection box 100 is explained using the example of the end recess 102, which is used during assembly of the

Terminal box 100 corresponds to the ground wire connection hole located on the upper part:

Connecting the cable L to the junction box 100 includes:

inserting the cable L into the constriction sleeve 201 via the recess 201a and rotating the second end head 203 to hold down the cable L; Please go through the details before assembly

Rotating the second end head 203, the second end head 203 can be opened. Now the cable

L inserted over the recess 201a. The position of the end portion of the cable L can be adjusted by pulling so that a part of the insulating layer LI is in the first clamping groove 202a and the second clamping groove 203a and the lead wire L2 is in the lowermost portion of the first

Clamping groove 202a and the second clamping groove 203a are located. After adjustment, the second one will be

End head 203 is pressed down and the cable L is clamped and fixed by means of the first hold-down strip 202b and the second hold-down strip 203b.

inserting the side shaft 202c into the oblique groove 103a to the bottom thereof; Due to the oblique arrangement of the oblique groove 103a, an end portion of the adapter element 200 contacts the electrically conductive plate 104 and presses it downward upon insertion

Adapter element 200 into the plug-in groove 203. Under the action of the first spring 105, the electrically conductive plate 104 lifts the end section of the adapter element 200 upwards, so that the side shaft 202c penetrates into the round groove 103b.

The push plate 102d is touched and pressed by the end section of the adapter element 200.

Turning the cable L; When the cable L is rotated upward, the side shaft 202c is always in the round groove 103b under the action of the first spring 105 and rotates around the round groove 103b until the cable L is in a vertical position, in which case the

Side wall of the adapter element 200 touches the limiting piece 102e. The pushes

Push plate 102d always holds the end portion of the adapter member 200 to maintain it in a vertical state; At the same time, the lateral shaft 202c is located in the round groove 103b and is subjected to an upward thrust force from the first spring 105 8

Y20P63LU-YUV003LU 04/26/2023 exposed, which prevents the adapter element 200 from being detached from the connection box 100 LU103109.

Furthermore, the electrical contact between the electrically conductive plate 104 and the end portion of the adapter element 200 is thus always maintained.

Removing the cable L from the junction box 100 includes:

pushing the cable L toward the electrically conductive plate 104; That is, in the present embodiment, the cable L is pressed downward, thereby pressing and moving the electrically conductive plate 104 so that the side shaft 202c is out of the round

Groove 103b penetrates into the oblique groove 103a.

Turning the cable L; After rotating the cable L, the push plate 102d pushes the end portion of the adapter member 200 so that the position of the side shaft 202c is offset from the round groove 103b. Now the cable L can simply be pulled out.
