The plurality of connection strings 111 are in communication with each other. At least two connecting columns 111 are provided with conductive positioning seats 112. The conductive positioning seat 112 is provided with a conductive positioning hole 113. The conductive pin 120 is installed in the conductive positioning hole 113 in a penetrating manner. Conductive pins 120 are independently installed in the conductive positioning holes 113. The conductive connection 130 electrically connects the conductive pins 120 located on different connection strings 111. The conductive multi-way joint 100 can not only transfer the fluid flowing in one connecting pipe column 111 to other connecting pipe columns 111, for example, divide the fluid into a plurality of connecting pipe columns 111 or realize fluid confluence, but also transfer a conductive loop used for connection in one connecting pipe column 111 to other connecting pipe columns 111.

Still further, the number of conductive pins 120 mounted on each conductive nest 112 is required to ensure that at least one conductive loop can be connected, so that by providing a plurality of branch connection strings having conductive nest 112, the conductive loop for connection by the main connection string can be branched into a plurality of branches, which may originate from the conductive pin 120 on the main connection string for connection to the same conductive loop or from the conductive pin 120 on the main connection string for connection to different conductive loops.

If the branched multi-strand is derived from the conductive pins 120 on the main connecting string for connecting different conductive loops, correspondingly, the conductive positioning seats 112 on the main connecting string are provided with a plurality of groups of conductive positioning holes 113, preferably, the conductive positioning holes 113 on different branch connecting strings are respectively close to the conductive positioning holes 113 on different groups of the main connecting string, so that the conductive connecting piece 120 is electrically connected with the conductive pins 120 on the main connecting string and the branch connecting string.

The multifunctional three-way joint not only can divide the fluid flowing in the main connecting pipe column into two streams, but also can branch the conductive needles 120 used for connecting four conductive loops on the main connecting pipe column to different branch connecting pipe columns.

As described above, the multiple strands branching from the main connection string may be the conductive pins 120 from the main connection string for connecting the same conductive loop, or may be the conductive pins 120 from the main connection string for connecting different conductive loops. When the multiple strands branched from the main connecting string originate from the conductive pins 120 on the main connecting string for connecting the same conductive loop, the conductive conditions of the devices connected to the branched connecting strings can be synchronously controlled; when the multiple strands branching from the main connecting string originate from the conductive pins 120 on the main connecting string for connecting different conductive loops, the conduction of the equipment connected to each branching connecting string can be independently controlled.

In one embodiment, the conductive positioning seat 112 is sleeved on the connection string 111.

Further, the conductive pin 120 is a single-ended telescopic elastic conductive pin, and one telescopic end passes through the conductive positioning hole 113 to be exposed in the gap 115 between the stop collar 114 and the connection pipe column 111.

In one embodiment, the conductive connection 130 is a PCB interposer. The PCB patch panel 130 is provided with conductive traces (not shown). Conductive pins 120 on different connection strings 111 are connected to the conductive traces on different sides of the PCB adapter plate, respectively. Preferably, the conductive pins 120 are directly electrically connected to the conductive traces of the PCB interposer by soldering. In the embodiment shown in fig. 2, referring to fig. 5, the pcb adapter plate is placed on the multi-way pipe 110, specifically, inside the conductive positioning seat 112. Further, in the embodiment shown in fig. 2, there are two PCB adapter plates respectively located at two sides of the multi-way pipe 110 to electrically connect the main connection pipe columns located at two sides of the multi-way pipe 110 and the conductive pins 120 on the branch connection pipe columns respectively. The conductive pins 120 on the different conductive positioning seats 112 are connected through the PCB adapter plate, so that the connection stability is better than that of the conductive pins by using a wire and other connection modes, the conductive pins 120 are more convenient to manufacture, one end of each conductive pin 120 is welded with a conductive circuit of the PCB adapter plate, the conductive pins 120 can be fixed from one end, and other fixing elements are not needed to be used for fixing the conductive pins 120.

One end of the conductive pin 120 is installed in the conductive mounting hole 141 in a penetrating manner, and the other end passes through the conductive positioning hole 113. As in the embodiment shown in fig. 2, referring to fig. 5, 6 and 7, the connection string 111 is cylindrical, and accordingly, the conductive mount 140 is kidney-shaped to fit with the outer wall of the connection string 111 to be stably mounted on the connection string 111.

Further, in one embodiment, a sealing post 152 is provided on the wrap 150. The outer diameter of the sealing post 152 is identical to the outer diameter of the connecting string 111, but the sealing post 152 is not in communication with the multi-way pipe 110. Through setting up seal post 152, when the connecting catheter 200 other end that is connected with the multi-way pipe 110 need not be connected with external equipment, but the direct insertion cover is on this seal post 152, and need not to carry out other sealing treatment to it, convenient operation, the practicality is strong.
