The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims. In the description of the present application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and do not have to be used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0031] In addition, in the description of this application, unless otherwise specified, "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0032] like Figure 1-5 As shown, a waterproof terminal structure and an external network circuit breaker include an elastic member 601 that maintains a predetermined distance between two parallel arranged first wiring parts 602 (which are flame retardant and high temperature resistant plastic parts) and a second wiring part 603 (which are flame retardant and high temperature resistant plastic parts);

[0033] A plurality of corresponding wire grooves are provided on adjacent surfaces of the first wiring portion 602 and the second wiring portion 603;

[0034] The wire slot on the first wiring part 602 is provided with a first rubber wire seat 6021 and the wire slot on the second wiring part 603 is provided with a second rubber wire seat 6031, and the second rubber wire seat 6031 is plugged into the embedded slot opened at the port of the first rubber wire seat 6021 to hold the wire in the wire slot.

[0035] Specific, combined Figure 1 It can be seen that a terminal block 600 is provided on the outside of the main body 100, the first terminal portion 602 and the second terminal portion 603 are both located inside the terminal block 600, and the push plate 608 provided on the first terminal portion 602 is rotatably connected to the end of the locking screw 500 threadedly connected to the main body 100.

[0036] Furthermore, a first elastic metal plate 6022 is disposed in the wire groove on the first wiring portion 602. A symmetrically arranged trapezoidal elastic plate 6032 is disposed in the wire groove on the second wiring portion 603, and the trapezoidal elastic plate 6032 corresponds to between the two first elastic metal plates 6022. Therefore, when the first wiring portion 602 is attached to the second wiring portion 603, the first elastic metal plate 6022 will be squeezed into between the two first elastic metal plates 6022, and the inserted wire will be firmly clamped due to elastic deformation, thereby achieving electrical connection between the wire and the body 100.

[0037] In the above technology, the first wiring part 602 is attached to the second wiring part 603, and the second rubber wire seat 6031 is inserted into the embedding groove of the first rubber wire seat 6021 to squeeze and deform the two to fix the inserted wire, thereby achieving sealing. If the first wiring part 602 and the second wiring part 603 are restored to the initial state under the action of the elastic member 601, the clamp seal is cancelled to prevent the wire from being decoupled, so the loosening of the locking screw 500 will not cause the loss of the waterproof effect.

[0038] As an embodiment further provided by the present invention, the first elastic metal plate 6022 is divided into an arc-shaped protrusion 60221 and a bending arm 60222 connected to both ends of the arc-shaped protrusion 60221 according to the structure.

[0039] Specifically, when the first wiring portion 602 is attached to the second wiring portion 603, the top of the arc-shaped protrusion 60221 contacts the wire, and then due to the reverse force provided by the wire, the bending arm 60222 bends and deforms, and the arc-shaped protrusion 60221 is applied to squeeze the wire.

[0040] As the optimal embodiment further provided by the present invention, the trapezoidal elastic plate 6032 is slidably connected to the trapezoidal guide slider 604 (a ceramic component) provided in the wire groove.

[0041] Furthermore, a tenon 605 is provided on the wire groove of the first wiring portion 602 for squeezing the side walls of the two trapezoidal elastic plates 6032 to bring them together.

[0042] Specifically, when the first wiring portion 602 is attached to the second wiring portion 603, the arc top of the arc-shaped protrusion 60221 contacts the wire, and then due to the reverse force provided by the wire, the bending arm 60222 is bent and deformed, and the arc-shaped protrusion 60221 is applied to squeeze the wire. At the same time, the two tenons 605 squeeze the two trapezoidal elastic plates 6032 toward the center, thereby squeezing the wire and the two ends of the arc-shaped protrusion 60221, and the two ends of the arc-shaped protrusion 60221 apply a reverse force, so that the trapezoidal elastic plate 6032 and the contact end of the side of the trapezoidal guide slider 604 are firmly pressed.

[0043] As another embodiment further provided by the present invention, the elastic member 601 includes guide posts 606 symmetrically arranged on the first wiring portion 602 , and the guide posts 606 are connected to equidistant springs 607 arranged in borings opened on the second wiring portion 603 .

[0044] Specifically, when the locking screw 500 loses its thrust force on the thrust plate 608 , the equidistant spring 607 returns to its original state, so that the first wiring portion 602 and the second wiring portion 603 arranged in parallel return to an equidistant state.

[0045] According to the disclosure and teaching of the above description, those skilled in the art to which the present invention belongs may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
