Description
技术领域 technical field
本发明涉及母线连接器，具体涉及配电柜中用于直母线连接的四通母线连接器。 The invention relates to a busbar connector, in particular to a four-way busbar connector used for connecting straight busbars in a power distribution cabinet. the
背景技术 Background technique
配电柜中复杂的母线布局常常需要占用较大的空间，为了保证母线在配电柜中排列整齐，所占空间小，用于配电柜与母线之间连接的母线连接器除了能够实现母线与配电柜之间的连接，还需要能够保证母线在配电柜上的整齐布局，以使配电柜能够小型化、标准化。中国专利文献CN201113244Y公开的套管靴，所述套管靴由第一锥套管、第二锥套管、左套管和右套管组成。所述第一锥套管和所述第二锥套管在一条直线上，所述左套管和所述右套管的中心线在与所述第一锥套管和所述第二锥套管的中心线垂直的平面上，所述左套管与所述右套管中心线的夹角为70-110°，所述第一锥套管、第二锥套管、左套管和右套管彼此相通。使用时，两个弯母线分别从左右套管穿入连接，第二锥套管与绝缘桶上的锥桶配合，第一锥套管与绝缘后封堵配合。中国专利文献CN101383489B是该种套管靴的实际使用，该专利文献公开了一种异形母线及其排列方法,它包括绝缘层、导电芯和连接头,连接头在导电芯的两端,并与导电芯为一体,导电芯的外部包裹的绝缘层是由硅橡胶制成的,导电芯为圆弧形,导电芯两端的连接头相距300-600mm,导电芯最大弯度与导电芯两端的连接头连线之间的距离为100-200mm,第一排异形母线排列在若干个接线柱的一侧,第二排异形母线排列在若干个接线柱的另一侧,直母线排列在第一排异形母线和第二排异形母线的下方或上方,该异形母线的排列分为上下两层,该种排列方式通过异形母线的弧度,能使固体绝缘全密封开关绝缘罩与套管靴连接处的接线柱在一条直线上,便于除母线外其他零件标准化以及减少占用空间,能使整个柜体标准化、小型化。 The complex busbar layout in the power distribution cabinet often needs to occupy a large space. In order to ensure that the busbars are arranged neatly in the power distribution cabinet and occupy a small space, the busbar connectors used for the connection between the power distribution cabinet and the busbar can not only realize the busbar The connection with the power distribution cabinet also needs to be able to ensure the neat layout of the busbar on the power distribution cabinet, so that the power distribution cabinet can be miniaturized and standardized. Chinese patent document CN201113244Y discloses a casing shoe, the casing shoe is composed of a first tapered casing, a second tapered casing, a left casing and a right casing. The first tapered sleeve and the second tapered sleeve are on a straight line, and the centerlines of the left sleeve and the right sleeve are aligned with the first tapered sleeve and the second tapered sleeve On a plane perpendicular to the center line of the pipe, the angle between the left casing and the center line of the right casing is 70-110°, and the first tapered casing, the second tapered casing, the left casing and the right The sleeves communicate with each other. When in use, the two bent busbars are connected through the left and right bushings respectively, the second taper bushing cooperates with the taper barrel on the insulation barrel, and the first taper bushing cooperates with the insulating rear plug. Chinese patent document CN101383489B is the actual use of this kind of bushing boot. This patent document discloses a special-shaped busbar and its arrangement method. It includes an insulating layer, a conductive core and a connector. The conductive core is integrated, and the insulating layer wrapped outside the conductive core is made of silicone rubber. The conductive core is arc-shaped, and the distance between the connectors at both ends of the conductive core is 300-600mm. The distance between the connecting lines is 100-200mm. The first row of special-shaped busbars is arranged on one side of several terminal posts, the second row of special-shaped busbars is arranged on the other side of several terminal posts, and the straight busbars are arranged on the first row of special-shaped busbars. Below or above the busbar and the second row of special-shaped busbars, the arrangement of the special-shaped busbars is divided into upper and lower layers. This arrangement can make the connection between the solid-insulated fully-sealed switch insulation cover and the casing boot through the arc of the special-shaped busbar. The columns are on a straight line, which facilitates the standardization of other parts except the busbar and reduces the occupied space, and enables the standardization and miniaturization of the entire cabinet.
由中国专利文献CN101383489B可知，要实现三排母线的接线柱均在一条直线上的布置，套管靴也就是母线连接头不仅需要设计一套连接直母线的，还要设计一套连接异形母线的，即只有通过直母线、连接直母线的连接头、异形母线、连接异形母线的连接头四种部件的配合安装才能实现，而在生产这四种部件时又必须分别设计不同的模具，无疑增加了生产成本。此外，为了实现三排母线的接线柱均在一条直线上的布置，连接直母线的连接头的高度必须长于异形母线的连接头的高度，才能使得直母线的设置不受连接异形母线连接头的影响，但是这样的结构又无疑占据了配电柜内竖直方向的空间。 According to the Chinese patent document CN101383489B, in order to realize the arrangement of the terminals of the three rows of busbars on a straight line, the bushing shoe, that is, the busbar connector, not only needs to design a set of connecting straight busbars, but also a set of connecting special-shaped busbars. , that is, it can only be realized through the coordinated installation of the four parts of the straight busbar, the connector connected to the straight busbar, the special-shaped busbar, and the connector connected to the special-shaped busbar. However, when producing these four parts, different molds must be designed separately, which undoubtedly increases production cost. In addition, in order to realize the arrangement of the terminals of the three rows of busbars on a straight line, the height of the connectors connected to the straight busbars must be longer than the height of the connectors of the special-shaped busbars, so that the setting of the straight busbars will not be affected by the connectors connected to the special-shaped busbars. However, such a structure undoubtedly occupies the vertical space in the distribution cabinet. the
