The connecting spring 202 is used to push the metal jaw 201 to move toward the outside of the fixed cavity 102. The metal jaw 201 is used to fix and clamp the wire. The connecting spring 202 connects the metal jaw 201 and the stop block 101. The stop block 101 is provided with a clamping member 103, and the clamping member 103 is used to fix the metal jaw 201. The metal jaw 201 is semicircular, and the fixed cavity 102 is provided with upper and lower sets of metal jaws 201 separated from each other.
初始状态下，卡接件103与金属颚201相互固定，连接弹簧202处于压缩状态，在卡接件103的固定状态下，连接弹簧202无法推动金属颚201朝着固定腔102外部移动；使用时，将待连接导线自连接壳体100两端***固定腔102内，导线穿过两组金属颚201之间的间隙到达止动块101位置处，导线与止动块101相抵接并触发卡接件103，使得卡接件103与金属颚201相分离，金属颚201在连接弹簧202的作用下朝着固定腔102外部移动，由于固定腔102由中间向两侧逐渐收缩呈圆台状，两组金属颚201之间的间距在固定腔102内壁的作用下逐渐减小，从而夹紧固定***的导线，一端导线电流传递给金属颚201，流过金属颚201将电流传到连接壳体100内壁，然后传到另一端的金属颚201，最后通过金属颚201传给另一端导线，完成导线间的固定连接。In the initial state, the clamping member 103 and the metal jaw 201 are fixed to each other, and the connecting spring 202 is in a compressed state.

The metal jaw 201 moves toward the outside of the fixed cavity 102 under the action of the connecting spring 202. Since the fixed cavity 102 gradually shrinks from the middle to both sides to form a truncated cone shape, the two groups The distance between the metal jaws 201 gradually decreases under the action of the inner wall of the fixed cavity 102, thereby clamping and fixing the inserted wire. The current of the wire at one end is transmitted to the metal jaw 201, and the current flows through the metal jaw 201 and is transmitted to the inner wall of the connection housing 100. , then transmitted to the metal jaw 201 at the other end, and finally transmitted to the wire at the other end through the metal jaw 201 to complete the fixed connection between the wires.

参照图1至图3，为本实用新型第二个实施例，其不同于第一个实施例的是：止动块101中部开设有连接腔101a，连接腔101a两侧开设有向止动块101边缘延伸的位移槽101b。卡接件103包括伸缩圆台103a、位移杆103b和第一卡接头103c，伸缩圆台103a通过压缩弹簧103d安装于连接腔101a内，位移杆103b活动设置于位移槽101b内，一端与伸缩圆台103a相抵接，另一端固定有第一卡接头103c。伸缩圆台103a自止动块101端外半径逐渐增大。Referring to Figures 1 to 3, a second embodiment of the present invention is shown. What is different from the first embodiment is that a connecting cavity 101a is provided in the middle of the stopper 101, and directional stoppers are provided on both sides of the connection cavity 101a. The displacement groove 101b extends from the edge of 101. The clamping member 103 includes a telescopic circular cone 103a, a displacement rod 103b and a first clamping joint 103c. The telescopic circular cone 103a is installed in the connection cavity 101a through a compression spring 103d. The displacement rod 103b is movably arranged in the displacement groove 101b, and one end is against the telescopic circular cone 103a. Connect, and the first card connector 103c is fixed at the other end. The outer radius of the telescopic circular cone 103a gradually increases from the end of the stop block 101.
金属颚201靠近止动块101的一端连接有固定杆201a，固定杆201a端部设置有第二卡接头201b，第二卡接头201b和第一卡接头103c卡接固定，卡接固定面为垂直面。One end of the metal jaw 201 close to the stopper 101 is connected to a fixed rod 201a. The end of the fixed rod 201a is provided with a second clamping joint 201b. The second clamping joint 201b and the first clamping joint 103c are clamped and fixed. The clamping fixing surface is vertical. noodle.
正常状态下，在压缩弹簧103d的作用下，伸缩圆台103a从止动块101中部的连接腔101a内伸出，位移杆103b与伸缩圆台103a侧面相抵接，位移杆103b端部的第一卡接头103c和固定杆201a端部的第二卡接头201b相卡接，二者的卡接固定面为垂直面，从而防止第一卡接头103c和第二卡接头201b脱落，在二者的卡接固定作用下，金属颚201能够克服连接弹簧202的压力，保持固定状态，连接弹簧202同时保持压缩状态。Under normal conditions, under the action of the compression spring 103d, the telescopic truncated cone 103a extends from the connecting cavity 101a in the middle of the stop block 101, the displacement rod 103b abuts the side of the telescopic truncated cone 103a, and the first snap joint at the end of the displacement rod 103b 103c is engaged with the second clamping joint 201b at the end of the fixed rod 201a, and the clamping and fixing surface of the two is a vertical surface, thereby preventing the first clamping joint 103c and the second clamping joint 201b from falling off. Under the action, the metal jaw 201 can overcome the pressure of the connection spring 202 and maintain a fixed state, while the connection spring 202 maintains a compressed state.
在***导线后，导线进入固定腔102内穿过两组金属颚201之间的间隙到达止动块101位置处，继续向内推动导线直至导线与止动块101相抵接，在导线的作用下，压缩弹簧103d受力压缩，伸缩圆台103a进入连接腔101a内，由于伸缩圆台103a自止动块101端外半径逐渐增大，随着伸缩圆台103a逐渐进入连接腔101a内，两侧位移槽101b内的位移杆103b逐渐朝着止动块101外侧移动，直至位移杆103b端部的第一卡接头103c和固定杆201a端部的第二卡接头201b相分离，二者分离后，金属颚201的固定状态取消，压缩状态下的连接弹簧202推动金属颚201朝着固定腔102外部移动，由于固定腔102由中间向两侧逐渐收缩呈圆台状，两组金属颚201之间的间距在固定腔102内壁的作用下逐渐减小，从而夹紧固定***的导线。需要特别说明的是，伸缩圆台103a以及位移杆103b与伸缩圆台103a接触的端部为磁块，二者磁性相异，从而防止位移杆103b和伸缩圆台103a脱落。After inserting the wire, the wire enters the fixed cavity 102 and passes through the gap between the two sets of metal jaws 201 to reach the position of the stop block 101. The wire continues to be pushed inward until the wire contacts the stop block 101. Under the action of the wire , the compression spring 103d is compressed by force, and the telescopic circular cone 103a enters the connection cavity 101a. Since the outer radius of the telescopic circular cone 103a gradually increases from the end of the stop block 101, as the telescopic circular cone 103a gradually enters the connection cavity 101a, the displacement grooves 101b on both sides The displacement rod 103b inside gradually moves toward the outside of the stop block 101 until the first clamping joint 103c at the end of the displacement rod 103b and the second clamping joint 201b at the end of the fixed rod 201a are separated. After the two are separated, the metal jaw 201 The fixed state is cancelled, and the connecting spring 202 in the compressed state pushes the metal jaw 201 to move toward the outside of the fixed cavity 102. Since the fixed cavity 102 gradually shrinks from the middle to both sides to form a truncated cone shape, the distance between the two sets of metal jaws 201 is fixed. The inner wall of the cavity 102 gradually decreases, thereby clamping and fixing the inserted wire. It should be noted that the end portions of the telescopic truncated cone 103a and the displacement rod 103b that are in contact with the telescopic truncated cone 103a are magnetic blocks, and their magnetic properties are different, thereby preventing the displacement rod 103b and the telescopic truncated cone 103a from falling off.

A marking displacement rod 201d is provided in the middle of the metal jaw 201, and a marking groove 104 is provided on the connecting shell 100. The marking displacement rod 201d extends through the marking groove 104 to the outside of the connecting shell 100, and can be displaced by moving the marking located in the marking groove 104. The rod 201d releases the clamping and fixing state of the wire by the metal jaw 201. At the same time, the marking displacement rod 201d can also indicate the moving position of the metal jaw 201.
当需要拔出固定腔102内的导线时，通过延伸至连接壳体100外侧的标识位移杆201d解除金属颚201对导线的夹紧固定状态，沿着标识槽104向止动块101方向移动标识位移杆201d，从而使得金属颚201放松对导线的夹紧，而后拔出导线，伸缩圆台103a在压缩弹簧103d的作用下还原，两侧位移槽101b内的位移杆103b也同步还原，拔出导线后，继续移动金属颚201还原至初始状态，当第二卡接头201b得第二斜面201c与第一卡接头103c的第一斜面103e接触时，在二者斜面的相互作用下，位移杆103b脱离伸缩圆台103a，直至第二卡接头201b的卡接固定面与第一卡接头103c的卡接固定面位于同一轴线，在伸缩圆台103a的吸引力下，位移杆103b重新与伸缩圆台103a抵接，第一卡接头103c和第二卡接头201b重新卡接固定，连接弹簧202重新保持压缩状态。When it is necessary to pull out the wire in the fixing cavity 102, the clamping and fixing state of the wire by the metal jaw 201 is released through the identification displacement rod 201d extending to the outside of the connection housing 100, and the identification is moved along the identification groove 104 toward the stop block 101. The displacement rod 201d causes the metal jaw 201 to loosen the clamping of the wire, and then the wire is pulled out. The telescopic circular cone 103a is restored under the action of the compression spring 103d, and the displacement rods 103b in the displacement grooves 101b on both sides are also restored simultaneously, and the wire is pulled out. Then, continue to move the metal jaw 201 to return to the initial state. When the second inclined surface 201c of the second clamping joint 201b contacts the first inclined surface 103e of the first clamping joint 103c, under the interaction of the two inclined surfaces, the displacement rod 103b breaks away. The telescopic truncated cone 103a is positioned on the same axis until the clamping and fixing surface of the second clamping joint 201b and the first latching joint 103c are located on the same axis. Under the attraction force of the telescopic truncated cone 103a, the displacement rod 103b contacts the telescopic truncated cone 103a again. The first clamping joint 103c and the second clamping joint 201b are clamped and fixed again, and the connection spring 202 maintains the compressed state again.
