具体实施方式 Detailed ways
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
本发明提供了一种电连接装置，用于在测试电缆时抵接在被试电缆端连接仓触头3和测试电缆端连接仓触头3’之间。The present invention provides an electrical connection device, which is used to abut between the contact 3 of the terminal connection compartment of the tested cable and the contact 3' of the connection compartment of the test cable end when the cable is tested.
图2是根据本发明第一实施例的用于导通电缆测试连接仓中触头的电连接装置的剖视图。该电连接装置10包括筒体11和活动件12。筒体11下端封闭，并具有法兰13，法兰13上设有螺孔15，用于与连接仓的触头3连接。筒体11的第二端具有开口，开口的直径与活动件12的外径适配而让活动件12穿过。活动件12为空心筒体，其通过下端的凸环122与筒体11的内壁接触，该凸环还起到止挡作用，其被筒体11的第二端的端壁止挡，防止活动件12脱离出筒体。弹簧16支撑在筒体11下端与活动件的顶端121之间，在筒体内还设有一个弹簧限位杆14，但是该限位杆不是必须的。活动件12的顶端121提供一个电接触面，用于抵接一个触头。Fig. 2 is a cross-sectional view of the electrical connection device for conducting the contacts in the cable test connection compartment according to the first embodiment of the present invention. The electrical connection device 10 includes a cylinder body 11 and a movable part 12 . The lower end of the cylinder body 11 is closed, and has a flange 13, and the flange 13 is provided with a screw hole 15 for connecting with the contact 3 of the connecting chamber. The second end of the barrel 11 has an opening, the diameter of the opening is adapted to the outer diameter of the movable part 12 to allow the movable part 12 to pass through. The movable part 12 is a hollow cylinder, which is in contact with the inner wall of the cylinder 11 through the protruding ring 122 at the lower end. 12 break away from the cylinder. The spring 16 is supported between the lower end of the cylinder body 11 and the top end 121 of the movable part, and a spring limit rod 14 is also arranged in the cylinder body, but the limit rod is not necessary. The top end 121 of the movable member 12 provides an electrical contact surface for abutting against a contact.
凸环122与筒体11的接触面、以及活动件12主体与筒体上端面之间的接触面应该光滑，不应有过大的摩擦力，而且要充分接触以致能良好导电。The contact surface between the protruding ring 122 and the barrel 11, and the contact surface between the main body of the movable part 12 and the upper end surface of the barrel should be smooth, should not have too much friction, and should be in sufficient contact so as to conduct electricity well.
图3是根据本发明另一个实施例的用于导通电缆测试连接仓中触头的电连接装置10的剖视图。与前一实施例的不同之处在于，活动件12的外壁设有螺纹17，与筒体12的开口螺纹配合，通过该螺纹可以调节活动件的伸缩程度。在这种情况下，活动件12主要通过下端的凸环122实现与筒体的电传导。在活动件12靠近顶端的侧壁可以设置一个或两个短杆，作为旋转活动件的手柄。也可以在侧壁上开孔，通过插入另外的棒来旋动活动件。还可以采用其他的方式来旋转活动件。例如，可以在活动件的顶端开一个多角螺帽孔，通过一个T形操作手柄来旋转活动件，T形手柄下端的插入部具有与多角螺帽孔相应的尺寸和形状。FIG. 3 is a cross-sectional view of an electrical connection device 10 for conducting contacts in a cable test connection compartment according to another embodiment of the present invention. The difference from the previous embodiment is that the outer wall of the movable part 12 is provided with a thread 17, which is threadedly matched with the opening of the cylinder 12, through which the degree of expansion and contraction of the movable part can be adjusted. In this case, the movable part 12 realizes electrical conduction with the barrel mainly through the protruding ring 122 at the lower end. One or two short rods can be arranged on the side wall near the top of the movable part 12 as a handle for rotating the movable part. It is also possible to make holes in the side walls and to rotate the movable part by inserting additional rods. Other ways can also be used to rotate the movable member. For example, a polygonal nut hole can be opened on the top of the movable part, and a T-shaped operating handle is used to rotate the movable part. The insertion part at the lower end of the T-shaped handle has a size and shape corresponding to the polygonal nut hole.
以上仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
