In order to achieve the above purpose, the utility model adopts the following technical scheme:

a rubber core structure comprising: the rubber core comprises a first rubber core, a plurality of step parts are formed on the cylindrical outer wall at one end of the first rubber core, the step parts extend upwards along the outer wall in an inclined mode, then extend downwards in a horizontal or inclined mode, and vertical stop bars are formed at the tail end of the step parts; a second rubber core; locate the second and glue the outer connection lid of core, connect and be equipped with in the lid and connect the lid lug, when rotatory when connecting the lid, connect the lid lug and be in along step portion is last the step portion removes.

Furthermore, a first notch is formed in front of one side of the stop bar and one side of the starting end of the step part.

Further, be equipped with the second lug on the second gluey core, it is equipped with the connection lid breach to connect to cover, first breach, connection lid lug, connection lid breach, second lug are in proper order alignd.

Furthermore, a second notch is formed in the second rubber core, and the first notch, the connecting cover bump, the second notch, the connecting cover notch and the second bump are sequentially aligned.

Further, the step portion includes two, sets gradually along the connection terminal outer wall.

Furthermore, the connecting cover bump comprises two bumps which are respectively matched with the two step parts.

Furthermore, a partition plate is arranged in the first rubber core. The cable conductor is used for increasing the creepage distance between the cable conductors.

Compared with the prior art, the beneficial effects of the utility model are that:

when the connecting cover is rotated, the connecting cover convex block moves along the step part, and when the connecting cover convex block moves to the vertical stop strip at the tail end of the step part, the connector can be locked, so that the force of rotating the connecting cover is not considered, the quick connection is realized, and the safety and the reliability are realized.

Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention can be embodied in many different forms other than those specifically described herein, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the invention, and it is therefore not to be limited to the specific embodiments disclosed below.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-6, the rubber core structure of the present invention includes a first rubber core 10 and a second rubber core 20. A plurality of step portions 11 are formed on the cylindrical outer wall at one end of the first rubber core 10, the step portions 11 extend upwards along the outer wall in an inclined manner, and then extend horizontally (or extend downwards in an inclined manner), including a vertical stop bar 12 formed at the tail end of the step portion. The first glue core 10 is provided with a partition 16. The cable conductor is used for increasing the creepage distance between the cable conductors.

As shown in fig. 1-6, a connection cover 21 is disposed outside the second rubber core 20, and a connection cover protrusion 22 is disposed inside the connection cover 21.

When the first rubber core 10 and the second rubber core 20 are well butted, the connecting cover 21 is rotated, the connecting cover convex 22 block moves along the step part, and the connector can be set to be locked when the connector moves to the vertical stop bar 12 at the tail end of the step part, so that the force applied by the rotating connecting cover 21 is not considered, the quick connection is realized, and the safety and the reliability are realized.
