A recess is formed on the inner wall so that a wire can pass through the concave side surface, and to take out a wire head for wiring, the wire is taken out through the recess and connected.

Note that in the control box 300, there is provided a snap plate 301 to which an electric element or the junction box 100 is fixed to facilitate wiring.

In the present invention, the junction box 100 is formed as a three-hole socket structure, which can serve for indirect connection for a three-prong plug. In detail, the three-pin connector is inserted into the cable insertion 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 an end area of the connection box 100 , the number of which corresponds to the number of the cable insertion hole 101 . For example, in the present embodiment, the cable insertion hole 101 is provided in a number of three, and accordingly, an end recess 102 is provided at the upper end of the junction box 100, which is electrically connected to a ground wire connecting hole of the cable insertion hole 101, while the lower end of the junction box 100 with two end grooves 102 which are electrically connected to a neutral connection hole and a live wire connection hole of the cable insertion hole 101, respectively.

In the present exemplary embodiment, the cable L is indirectly connected to the connection box 100 via the adapter element 200 . In detail, the cable L includes an insulating layer L1 and a lead wire L2. The adapter member 200 is for fixing an end portion of the cable L and for electrical connection with the lead wire L2, wherein an electrical connection between the cable L and the cable insertion hole 101 on the junction box 100 is established when the adapter member 200 with the end recess 102 on the junction box 100 is connected and is in electrical contact with it.

In detail, the constriction sleeve 201 is made of hard plastic and is provided with a recess 201a on its side surface. The cable can be pressed into the constriction sleeve 201 via the recess 201a. The first end head 202 is always fixed to the constriction sleeve 201, while the second end head 203 is rotatable relative to the constriction sleeve 201. It should be noted that each of the first end head 202 and the second end head 203 is an electrically conductive part and may be made of metal.

The present embodiment differs from the above embodiment in that a first clamping groove 202a is provided in the first end head 202, in which a first hold-down strip 202b is provided; while in the second end head 203 there is provided a second clamping groove 203a in which is provided a second hold down strip 203b, the second hold down strip 203b and the first hold down strip 202b being offset from each other.

Note that the size of the first clamping groove 202a and the second clamping groove 203a gradually decreases inward from an end portion in order to clamp the electric wire L2 and maintain contact therewith. In detail, the first hold-down strip 202b and the second hold-down strip 203b serve to clamp the insulating layer L1 and to fix the conducting wire L in the adapter element 200.

Provision is also made for the second hold-down strip 203b and the first hold-down strip 202b to be offset from one another and for the first hold-down strip 202b to be closer to the end section of the first end head 202 than the second hold-down strip 203b, so that the second hold-down strip 203b presses the insulating layer L1 and over the first hold-down strip 202b is moved out when, after inserting an end portion of the cable L into the first clamping groove 202a and the second clamping groove 203a, the second end head 203 is closed by turning. At this time, without an external force, the second hold-down strip 203b can hardly be moved beyond the first hold-down strip 202b by itself, maintaining the state where the first end head 202 and the second end head 203 clamp and fix the end portion of the electric wire.

Furthermore, it is provided that an end section of the terminal box 100 is provided on one side with an insertion groove 103 which is connected to the end recess 102; the side wall of the mating groove 103 is provided with a slanting groove 103a arranged obliquely, and an end portion of the slanting groove 103a is provided with a round groove 103b on one side.

Note that the end hole 102 is formed inward from an end portion of the terminal box 100 , while the fitting groove 103 is formed from a side surface of the terminal box 100 and connected to the end hole 102 . In detail, the end recess 102 and the mating 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 circular groove 103b is located on the side wall of the end recess 102. The oblique arrangement of the oblique groove 103a allows the circular groove 103b to be located at a lower position than the mating groove 103 in the end recess 102.

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 matches the size of the slanting groove 103a so that the side shaft 202c can move in the slanting groove 103a.

Provision is also made for an electrically conductive plate 104 to be arranged at an angle in the lowermost area of the end recess 102, which is connected at one end to the side wall of the end recess 102, with a first spring 105 being provided in the lowermost area 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 one end portion via a second spring 102c to the lowermost portion of the square groove 102a; An end portion of the push rod 102b is provided with a push plate 102d.

• Das Anschließen des Kabels L an den Anschlusskasten 100 umfasst:
  • Einsetzen des Kabels L über die Aussparung 201a in die Einengungshülse 201 und Drehen des zweiten Endkopfs 203, um das Kabel L niederzuhalten; Im Detail soll vor der Montage durch Drehen des zweiten Endkopfs 203 der zweite Endkopf 203 geöffnet werden. Nun wird das Kabel L über die Aussparung 201a eingesetzt. Die Position des Endabschnitts des Kabels L lässt sich durch Ziehen anpassen, sodass sich ein Teil der Isolierschicht L1 in der ersten Klemmnut 202a und der zweiten Klemmnut 203a und der Leitungsdraht L2 im untersten Bereich der ersten Klemmnut 202a und der zweiten Klemmnut 203a befindet. Nach der Anpassung wird der zweite Endkopf 203 nach unten gedrückt und mittels des ersten Niederhaltestreifens 202b und des zweiten Niederhaltestreifens 203b wird das Kabel L geklemmt und fixiert.

The following explains the manner of connecting the adapter element 200 to the junction box 100, using the example of the end recess 102, which corresponds to the ground wire connection hole on the upper part when the junction box 100 is assembled:

• Connecting cable L to junction box 100 involves:
  • 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; In detail, before assembly, the second end head 203 is to be opened by turning the second end head 203 . Now the cable L is inserted through the recess 201a. The position of the end portion of the cable L can be adjusted by pulling so that part of the insulating layer L1 is in the first clamping groove 202a and the second clamping groove 203a and the lead wire L2 is in the bottom of the first clamping groove 202a and the second clamping groove 203a. After the adjustment, the second end head 203 is pushed 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 lateral shaft 202c into the inclined groove 103a to the bottom thereof; Due to the oblique arrangement of the oblique groove 103a, an end portion of the adapter element 200 touches the electrically conductive plate 104 and presses it down after the adapter element 200 is inserted into the plug-in groove 203. Under the action of the first spring 105, the electrically conductive plate 104 lifts the end portion of the adapter element 200 upward so that the side shaft 202c enters the circular groove 103b.

At this time, the push plate 102d is touched and pressed by the end portion of the adapter member 200.

turning the cable L; When turning the cable L upwards, 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. At this time, the pushing plate 102d always pushes the end portion of the adapter member 200 to maintain it in a vertical state; At the same time, the side shaft 202c is located in the round groove 103b and is subjected to an upward pushing force of the first spring 105, thereby preventing the adapter member 200 from detaching from the junction box 100.

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

• Drücken des Kabels L in Richtung der elektrisch leitfähigen Platte 104; das heißt, in dem vorliegenden Ausführungsbeispiel wird das Kabel L nach unten gedrückt, womit die elektrisch leitfähige Platte 104 gedrückt und bewegt wird, sodass die seitliche Welle 202c aus der runden Nut 103b in die schräge Nut 103a eindringt.

Detaching 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 pushed down, thereby pushing and moving the electrically conductive plate 104, so that the side shaft 202c enters the slanting groove 103a from the round groove 103b.

turning the cable L; After rotating the cable L, the pushing 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.
