由此可见，本发明为三维空间的产品结构，将通讯接头内极1和通讯接头外极3利用模具在两者之间的间隙注塑尼龙66材质并形成中间绝缘层2，注塑成型后，在填充的尼龙66轴封处装有O型密封圈，以防通缆钻杆内高压水渗漏入通讯接头内极1的锥形孔内，导致通讯极无法对随钻测量探管进行实时供电和信号传输。将仪器双线接头组件进行装配，将导线与仪器连线极5通过M4X10十字槽盘头黄铜螺钉8拧紧固定，将已经连好导线的仪器双线接头组件通装入通讯接头组件内，以实现中心通讯极从接头外部引入接头内部的目的，同时实现通讯接头内极与通讯接头外极绝缘。将导线与外电极连接头9之间通过M4X5十字槽盘头黄铜螺钉10固定拧紧，再将已经连好导线的外电极连接头9通过标准公制螺纹装入通讯接头组件内，以实现将通讯外极信号引入随钻测量探管内部功能，同时实现引入随钻测量探管内部的通讯接头外极与通讯接头内极绝缘。仪器双线接头组件和外电极连接头在装入通讯接头组件内之前，需点上螺纹锁固胶，以防在煤矿井下随钻钻进时由于震动较大而导致仪器双线接头组件和外电极连接零件被震松，导致仪器双线接头组件内的仪器连线极5和通讯接头内极脱离，最终出现无法对随钻测量探管进行实时供电、也无法将测量探管的测量信号实时传输至孔口设备现象。It can be seen that the present invention is a three-dimensional product structure. The inner pole 1 of the communication joint and the outer pole 3 of the communication joint are injected into the gap between the two using a mold to form a nylon 66 material to form an intermediate insulating layer 2. After injection molding, the The filled nylon 66 shaft seal is equipped with an O-ring to prevent the high-pressure water in the cable drill pipe from leaking into the tapered hole of the inner pole 1 of the communication joint, so that the communication pole cannot provide real-time power supply to the measuring tube while drilling and signal transmission. Assemble the two-wire connector assembly of the instrument, tighten and fix the wire and the instrument connection pole 5 through the M4X10 cross-recessed pan-head brass screw 8, and put the two-wire connector assembly of the instrument that has been connected with the wire into the communication connector assembly. The purpose of introducing the central communication pole from the outside of the joint to the inside of the joint is realized, and at the same time, the inner pole of the communication joint is insulated from the outer pole of the communication joint. Fix and tighten the connection between the wire and the external electrode connector 9 with M4X5 cross-recessed pan-head brass screws 10, and then install the external electrode connector 9 that has been connected with the wire into the communication connector assembly through a standard metric thread to realize communication. The outer pole signal is introduced into the internal function of the measurement while drilling probe, and at the same time, the outer pole of the communication joint introduced into the interior of the measurement while drilling probe is insulated from the inner pole of the communication joint. Before installing the instrument’s two-wire connector assembly and the external electrode connector into the communication connector assembly, thread-locking glue needs to be applied to prevent the instrument’s two-wire connector assembly and the external electrode assembly from being The electrode connection part was shaken loose, causing the instrument connection pole 5 in the instrument's two-wire joint assembly to be separated from the inner pole of the communication joint. Finally, it was impossible to provide real-time power supply to the measurement probe while drilling, and it was also impossible to transmit the measurement signal of the measurement probe in real time. Transmission to orifice device phenomena.
由此可见，本发明的小型化通缆式双极供电及信号传输接头在煤矿井下实际应用上，通讯接头内部零部件连接稳定无震松，信号传输稳定可靠，通讯接头整体密封性能优越，安装及拆卸方便。此种结构对信号连接及抗震的可靠性有了大幅度的提高；通讯接头的密封措施对防12MPa的水压有着很好防漏效果。It can be seen that the miniaturized cable-through type bipolar power supply and signal transmission joint of the present invention is actually applied in coal mines. And easy to disassemble. This structure has greatly improved the reliability of signal connection and earthquake resistance; the sealing measures of communication joints have a good leak-proof effect against 12MPa water pressure.
