本发明涉及插头插座领域，尤其涉及一种铜管插头及花篮螺栓插座以及组合插头。The invention relates to the field of plug sockets, in particular to a copper pipe plug, a turnbuckle socket and a combination plug.
背景技术Background technique
目前市场上单个铜管插头(即公端子)和花篮螺栓插座(即母端子)对插时，在它们的结合处均采用热缩管进行绝缘保护，使用过程中铜管插头(公端子)和花篮螺栓插座(母端子)在对插次数多时，由于器件磨损导致铜管插头(公端子)和花篮螺栓插座(母端子)它们间配合度不如刚使用时那么紧密，且当外层热缩管收缩不够紧密时，容易因为电线的牵拉以及其它外力影响而导致铜管插头(公端子)和花篮螺栓插座(母端子)脱离开来，同时起绝缘保护作用的热缩管也偏离原来的位置，使铜管插头(公端子)和花篮螺栓插座(母端子)裸露在外，不能起绝缘保护作用，安全性差。At present, when a single copper tube plug (that is, male terminal) and a turnbuckle socket (that is, female terminal) are plugged together, heat shrinkable tubes are used for insulation protection at their joints. During use, the copper tube plug (male terminal) and When the turnbuckle bolt socket (female terminal) is plugged in many times, the fit between the copper tube plug (male terminal) and the turnbuckle bolt socket (female terminal) is not as tight as it was when it was first used due to the wear and tear of the device, and when the outer heat shrink tube When the shrinkage is not tight enough, it is easy to cause the copper tube plug (male terminal) and the turnbuckle socket (female terminal) to separate due to the pulling of the wire and other external forces, and the heat shrinkable tube that acts as insulation protection also deviates from the original position , so that the copper pipe plug (male terminal) and the turnbuckle socket (female terminal) are exposed, which cannot play the role of insulation protection, and the safety is poor.

当铜管插头20和花篮螺栓插座21相对接时，即当绝缘胶壳1上的铜管插12入绝缘基座6上的花篮螺栓14时，第一凸台5和第二凸台9相对接在一起，此时使螺帽16上的螺纹部17一面先穿过铜管插头20，然后旋转螺帽16与第二凸台9上的外螺纹10相连接，直到螺帽16上的卡环部18抵到铜管插头20的第一凸台5为止。When the copper pipe plug 20 is connected to the turnbuckle socket 21, that is, when the copper pipe on the insulating plastic shell 1 is inserted into the turnbuckle 14 on the insulating base 6, the first boss 5 and the second boss 9 are opposite to each other. Connect together, make the threaded portion 17 on the nut 16 pass through the copper pipe plug 20 first, then rotate the nut 16 to connect with the external thread 10 on the second boss 9 until the clamp on the nut 16 The ring portion 18 touches the first boss 5 of the copper pipe plug 20 .
作为本发明的示意性实施例，在绝缘胶壳1上的第二端面到第一端面的方向上，所述第二腔体3的内径逐步变大直到等于第一腔体2的内径；在绝缘基座6上的第二端面到第一端面的方向上，所述第四腔体8的内径逐步变大直到等于第三腔体7的内径。As an exemplary embodiment of the present invention, in the direction from the second end surface to the first end surface on the insulating plastic shell 1, the inner diameter of the second cavity 3 gradually increases until it is equal to the inner diameter of the first cavity 2; In the direction from the second end surface on the insulating base 6 to the first end surface, the inner diameter of the fourth cavity 8 gradually increases until it is equal to the inner diameter of the third cavity 7 .
作为本发明的示意性实施例，所述第一凸台5沿轴向方向的长度小于所述第二凸台9沿轴向方向的长度。当铜管插头20和花篮螺栓21相对接时，用螺帽16固定连接，因为第二凸台9上设有外螺纹10，当第二凸台9沿轴向方向的长度大于第一凸台5沿轴向方向的长度时，螺帽16上的螺纹部17能有更大的接触面积和第二凸台9上的外螺纹10连接，保证铜管插头20和花篮螺栓21连接更紧密；进一步只在第二凸台9上设有外螺纹，在第一凸台5上没有设置，这是为了方便螺帽16对铜管插头20和花篮螺栓21插座进行连接。As an exemplary embodiment of the present invention, the length of the first boss 5 along the axial direction is smaller than the length of the second boss 9 along the axial direction. When the copper pipe plug 20 is connected with the turnbuckle bolt 21, it is fixedly connected with the nut 16, because the second boss 9 is provided with an external thread 10, when the length of the second boss 9 in the axial direction is greater than that of the first boss 5. When the length is along the axial direction, the threaded part 17 on the nut 16 can have a larger contact area to connect with the external thread 10 on the second boss 9, so as to ensure a tighter connection between the copper pipe plug 20 and the turnbuckle bolt 21; Further, external threads are only provided on the second boss 9, and not provided on the first boss 5, this is for the convenience of the nut 16 to connect the copper pipe plug 20 and the turnbuckle 21 socket.
本发明结构简单，通过设置配套绝缘胶壳和绝缘基座，把铜管和花篮螺栓通过螺纹连接分别安装在绝缘胶壳和绝缘基座内，然后通过螺纹帽把绝缘胶壳和绝缘基座固定连接。采用绝缘胶壳和绝缘基座的连接方式取代传统的热缩管连接，绝缘性好安全度高，能有效防止铜管和花篮螺栓因为松紧度问题而脱离开，以及热缩管收缩不紧时产生偏离等问题。The invention has a simple structure. By setting the matching insulating rubber shell and the insulating base, the copper pipe and the flower basket bolt are respectively installed in the insulating rubber shell and the insulating base through screw connection, and then the insulating rubber shell and the insulating base are fixed by the threaded cap. connect. The connection method of the insulating rubber shell and the insulating base is used to replace the traditional heat shrinkable tube connection, which has good insulation and high safety, and can effectively prevent the copper tube and the turnbuckle from being separated due to tightness problems, and when the heat shrinkable tube does not shrink tightly. Problems such as deviation occur.
