In addition, the shapes, sizes, thicknesses, angles and other related parameters of the components in the drawings are not drawn in proportion. The simplification is intended only for the convenience of clear description.

Referring to Figures 3, 4, and 5, the first embodiment of the novel isolator 100 includes a base 10 and an electronic circuit subassembly 90 mounted on the base 10. Preferably, the outer surface of the base 10 can be covered with an insulating material 11, and the insulating material can be plastic, silicone, or rubber. The base 10 includes a first connection port 101, a second connection port 102, and an insulating gasket 103 disposed on the first connection port 101. In this embodiment, the base 10 is hollow and further includes a first annular wall 104 and a second annular wall 105. The first annular wall 104 and the second annular wall 105 are respectively connected to the first connection port 101 and the second connection port 102 and both extend toward the inside of the base 10.

Referring to Figures 6, 7, and 8, the electronic circuit subassembly 90 includes a first circuit module 2, a second circuit module 3, and a connecting element 4. The first circuit module 2 includes a first integrated circuit board 21, a first housing 22, a connector 23, an insulating annular member 24, a main iron powder core 25, an insulating sleeve 26, a first contact member 27, and a first insulating member 28.

The first integrated circuit board 21 includes a first annular circuit board 211 and a second annular circuit board 212 both of which are arranged around a central axis L1, a plurality of first capacitors 213, a plurality of second capacitors 214, and a secondary iron powder core 215 arranged around the central axis L1. The first capacitors 213 are evenly distributed on the first annular circuit board 211 with the central axis L1 as the symmetric center. Similarly, the second capacitors 214 are evenly distributed on the second annular circuit board 212 with the central axis L1 as the symmetric center. The first capacitors 213 and the second capacitors 214 may be in the form of sheets but are not limited to sheets. For example, their capacitance values may be 4700pF, 5600pF, or 10000pF, and may be mixed with other capacitance values. The secondary iron powder core 215 is located between the first annular circuit board 211 and the second annular circuit board 212.

The first shell 22 is made of metal and surrounds and contacts the first integrated circuit board 21. The first shell 22 is electrically connected to the ground terminal 216 of the first annular circuit board 211. Preferably, the first shell 22 is further electrically connected to the ground terminal 217 of the second annular circuit board 212.

Referring to Figures 5, 7, and 8, the connector 23 is made of metal and is sleeved in the insulating gasket 103 of the base 10. The connector 23 has a head section 231, a tail section 232, and two extensions 233. Part of the outer circumference of the head section 231 is in close contact with the inner surface of the insulating gasket 103. The tail section 232 has a small diameter section 234, whose inner diameter is smaller than the inner diameter of the head section 231.

In some embodiments, the joint 23 has only one extension portion 233, and the outer circumference of the insulating annular member 24 also forms only one groove 241, so that the joint 23 and the insulating annular member 24 can be embedded into each other as a whole.

The main iron powder core 25 is sleeved on the insulating annular member 24 and surrounds the connecting element 4. The insulating sleeve 26 is sleeved on the tail section 232 of the joint 23, and the outer surface of the insulating sleeve 26 matches the inner circumferential surface shape of the first annular wall 104 of the seat body 10. The insulating sleeve 26 is used to isolate the electrical conduction between the joint 23 and the seat body 10. At the same time, the outer shape of the insulating sleeve 26 matches the shape of the first connecting port 101 of the seat body 10, for example, a hexagon or other polygon, thereby increasing the matching of multiple planar structures to enhance torque.

Referring to FIGS. 5 and 6 , the second circuit module 3 is disposed adjacent to the second connection port 102 and includes a second integrated circuit board 31, a second housing 32, a second contact 33, and a second insulating member 34. The second integrated circuit board 31 has a substrate 311 and a lightning protection assembly 312. A second conductive circuit 313 is formed on the substrate 311, and two grounding conductive portions 314 are located on both sides of the second conductive circuit 313. Each grounding conductive portion 314 has two grounding conductive layers formed on opposite surfaces of the substrate 311. The second conductive circuit 313 extends along the length direction of the second integrated circuit board 31 and has a first contact point 315 and a second contact point 316. The second contact point 316 of the second conductive circuit 313 is electrically connected to the second contact 33. The lightning protection component 312 is electrically connected to the second contact 33 and the second conductive circuit 313. The lightning protection component 312 is one of a lightning protection tube, a choke and a high pass filter.

The second housing 32 does not completely surround the second integrated circuit board 31. In this embodiment, the second housing 32 includes an upper half 321 and a lower half 322 disposed on the substrate 311, and the second housing 32 is electrically connected to the ground conductive portion 314 of the substrate 311 of the second integrated circuit board 31.

Referring to Figures 5, 6, and 7, the connection element 4 electrically connects the first integrated circuit board 21 and the second integrated circuit board 31. In this embodiment, the connection element 4 penetrates the first integrated circuit board 21 and has a first conductive circuit 41 and a ground circuit 42 located therein. The first end 411 of the first conductive circuit 41 of the connection element 4 is surrounded by a portion of the connector 23, the first end 411 of the first conductive circuit 41 is electrically connected to the first contact 27, and the second end 412 of the first conductive circuit 41 is electrically connected to the first contact point 315 of the second conductive circuit 313.

In detail, in this embodiment, the connecting element 4 is a coaxial cable, which includes a central conductor, an insulating layer, a braided layer, and a plastic skin layer in order from the inside to the outside in the radial direction, wherein the central conductor is made of copper, iron, silver, nickel, gold, copper-gold alloy, copper-tin alloy, copper-nickel alloy or other polymers with good electrical conductivity or non-metallic conductors, etc., and The material of the braided layer is a metal layer containing aluminum, a metal layer containing copper, or a conductive layer containing a conductive material, such as an aluminum wire coating layer or a copper wire coating layer. The braided layer has an electrical shielding effect and can reduce interference. The braided layer includes different coating forms such as two-layer braiding (Standard), three-layer braiding (Tri-shield) and four-layer braiding (Quad). In this embodiment, the first conducting circuit 41 of the connecting element 4 is the central conductor of the coaxial cable, which is used to transmit electrical signals; the grounding circuit 42 of the connecting element 4 is the braided layer of the coaxial cable. In addition, the braided layer of the coaxial cable can be connected to the first annular circuit board 211 and the second annular circuit board 212 by welding. A grounding spring 43 is provided between the small diameter portion 234 of the connector 23. One end of the grounding spring 43 contacts the grounding circuit 42 of the connecting element 4 (i.e., the braided layer of the coaxial cable), and the other end contacts the small diameter portion 234 of the connector 23. Thus, a good electrical connection is provided through good contact between the three, wherein the electrical connection is ground.

Referring to FIGS. 5 and 6 , the advantages of the novel isolator 100 are described below through the steps of installing the novel electronic circuit subassembly 90 on the base 10: first, the first circuit module 2 is sleeved in the first annular wall 104 of the base 10, and the connector 23 is passed through the first connection port 101 of the base 10, so that the first circuit module 2 is disposed adjacent to the first connection port 101, wherein the first annular wall 104 surrounds and contacts the first shell 22, and the small diameter portion 234 of the connector 23 of the first circuit module 2 is electrically connected to the ground circuit 42 of the connecting element 4; then the insulating gasket 103 is plugged into the first connection port 101 to prevent electrical conduction between the connector 23 and the base 10. In some embodiments, the base 10 may be pre-coated with a layer of insulating material on the surface in contact with the connector 23 to form an insulating portion. In this way, even if the insulating gasket 103 is omitted, the purpose of preventing the connector 23 and the base 10 from being electrically conductive can be achieved, that is, the connector 23 is insulated from the first connection port 101 of the base 10 through the insulating portion.

Next, the second circuit module 3 is sleeved in the second annular wall 105 of the base body 10, so that the second circuit module 3 is arranged adjacent to the second connection port 102, and then the assembly is completed to obtain the novel isolator 100.

Referring to FIGS. 5 and 9 , in the use of the novel isolator 100 , the direction of the electrical signal transmission is from the first contact 27 through the first conductive circuit 41 of the connecting element 4, the second conductive circuit 313 of the second integrated circuit board 31, and then through the second contact 33 located in the second connection port 102 to be output externally. The electrical signal transmission path is shown by the first arrow A1 in FIG. 9 ; it is worth mentioning that the electrical signal is During the transmission process, the main iron powder core 25, the auxiliary iron powder core 215 of the first integrated circuit board 21, and the first capacitor 213 and the second capacitor 214 are passed through. In this way, the abnormal voltage can be removed to prevent the electrical signal in the transmission process from being accompanied by abnormal signals. The invention is provided with a lightning protection component 312 on the second integrated circuit board 31, so that the invention isolator 100 can be effectively protected from being damaged by lightning strikes.

In addition, the second arrow A2 in FIG. 9 passes through the small diameter portion 234 of the connector 23, the grounding spring 43, the grounding circuit 42 (woven layer) of the connecting element 4 (coaxial cable), the grounding end 216 of the first annular circuit board 211 (as shown in FIG. 7), the first shell 22, the first annular wall 104 of the base 10, and the second connection port 102 of the base 10, so that the new isolator 100 has a good grounding effect in use, which can ensure the quality of signal reception.

Referring to Figures 10 and 11, the first variant embodiment of the novel electronic circuit subassembly 80 can also be installed on the base 10 having the first connection port 101 and the second connection port 102. The novel electronic circuit subassembly 80 includes a first circuit module 5, a second circuit module 6 and a connection element 7.

The capacitors 561 of the first functional module 56 are arranged on the substrate 511 and are symmetrically located on two opposite surfaces of the substrate 511. The auxiliary iron powder core 562 is located between the capacitors 561. The first functional module 56 thereby provides the functions of isolating signal noise and lightning protection.

The second integrated circuit board 61 has a second functional module 66, and the second functional module 66 includes one of a lightning arrester, a choke and a high-pass filter, or other circuit designs that can achieve a lightning protection function. It is worth mentioning that the first functional module 56 and the second functional module 66 can be designed according to actual needs so that one has a signal isolation function and the other has a lightning protection function, or has both a signal isolation function and a lightning protection function, or has other functions such as amplifying signals.

The first housing 52 of the first circuit module 5 and the first connector 53 are connected together through the first connection sleeve 54. The first connector 53 passes through the first connection port 101 of the base 10, and the first insulating gasket 55 is plugged in the first connection port 101 to prevent electrical conduction between the first connector 53 and the base 10. Similarly, the second housing 62 of the second circuit module 6 and the second connector 63 are connected together through the second connection sleeve 64. The second connector 63 passes through the second connection port 102 of the base 10, and the second insulating gasket 65 is plugged in the second connection port 102 to prevent electrical conduction between the second connector 63 and the base 10. The connecting element 7 includes a first conductive circuit 71 located therein, and the first conductive circuit 71 has a first end 711 electrically connected to the first integrated circuit board 51, and a second end 712 electrically connected to the second integrated circuit board 61. In addition, the direction in which the first circuit module 5 of the electronic circuit subassembly 80 is installed in the base 10 and the direction in which the second circuit module 6 is installed in the base 10 can be the same but located on different horizontal planes, or the first circuit module 5 and the second circuit module 6 are located on the same horizontal plane but facing different installation directions (as shown in FIG. 11), wherein the first end 711 and the second end 712 of the connecting element 7 are arranged opposite to each other in a free state. In addition, in the accommodation space defined by the base 10, the distance between the first circuit module 5 and the second circuit module 6 can be very close, and the first circuit module 5 and the second circuit module 6 can even be separated into different spaces through a partition. In other words, the shape and internal structure of the new base can be designed into different shapes or different internal structures according to actual applications, and there is no need for special restrictions.

In the use of the isolator disclosed in FIG. 11 , the direction of electrical signal transmission is from the first contact 27 in the first connection port 101 through the first functional module 56 of the first integrated circuit board 51, the connection element 7, the second functional module 66 of the second integrated circuit board 61, and then output to the outside through the second contact 33 located in the second connection port 102.

In some embodiments, the connecting element may be a flexible printed circuit board (FPC), the first conductive circuit is located in the flexible printed circuit board, and the flexible printed circuit board has a first end and a second end that are oppositely arranged. In addition, the connecting element may also be, but is not limited to, a wire or a cable.

In some embodiments, when the first functional module located on the first integrated circuit board or the second functional module located on the second integrated circuit board does not have a signal isolation function, the first circuit module or the second circuit module may even omit the corresponding first housing and second housing.

Referring to Figures 12 and 13, the second variation of the electronic circuit subassembly 70 of the present invention varies in the number of the first circuit modules 5 or the second circuit modules 6. For example, the electronic circuit subassembly 70 of the present invention further includes one or more first circuit modules 5 or second circuit modules 6. Each first circuit module 5 and each second circuit module 6 can be arbitrarily arranged on the base 10 in different installation directions according to application requirements in the XYZ coordinate system.

Based on the above description, the advantages of the new isolator and its electronic circuit subassembly can be summarized as follows:

1. This new electronic circuit subassembly can be installed on various shapes of bases and is very practical. It has the advantages of few assembly steps, simplicity and quick installation.

Second, the new electronic circuit subassembly has a sophisticated structure and does not require a bulky mounting base, which can effectively reduce the overall size of the isolator, thereby improving the shortcomings of the known signal isolator, which is bulky and consumes space.

3. This new isolator has good electrical signal isolation effect and is not only applicable to the 0 to 1.8 GHz frequency band, but also to higher frequency bands.

Referring to FIG. 14 , it is a second embodiment of the novel isolator 200. The second embodiment is similar to the first embodiment, and the main difference is that the base 20 is L-shaped and further includes a base wall 201 and a vertical wall 202. The first connection port 203 and the second connection port 204 are formed on the vertical wall 202. The base 20 also includes a first annular wall 205 connected to the first connection port 203, and a second annular wall 206 connected to the second connection port 204. The first circuit module 2 and the second circuit module 3 are respectively arranged in the first annular wall 205 and the second annular wall 206, and the base wall 201 is electrically connected to the first housing 22 of the first circuit module 2.

In this way, the second embodiment can also achieve the same effect and purpose as the first embodiment.

Referring to FIG. 15 , it is a third embodiment of the novel isolator 300. The third embodiment is similar to the first embodiment, and the main difference is that the base 30 is in a sheet shape and also has a vertical wall 301, a first annular wall 304, and a second annular wall 305. The first connection port 302 and the second connection port 303 are formed on the vertical wall 301. The first annular wall 304 extends outward from the first connection port 302, and the second annular wall 305 extends outward from the second connection port 303. The first circuit module 2 and the second circuit module 3 are respectively disposed in the first annular wall 304 and the second annular wall 305.

In this way, the third embodiment can also achieve the same effect and purpose as the first embodiment.

In summary, the novel isolator and its electronic circuit subassembly utilize the coaxial design concept. One end uses multiple capacitors and auxiliary iron powder cores in the first integrated circuit board of the first circuit module to achieve the effect of abnormal signal isolation, and the other end uses lightning arresters or other parts in the second integrated circuit board of the second circuit module to achieve the lightning protection effect. It is also explained that the lightning arrester or other parts with lightning protection function do not have to be integrated in the second integrated circuit board of the second circuit module, but can also be integrated in the first integrated circuit board of the first circuit module. The novel isolator and its electronic circuit subassembly have a sophisticated structure and can effectively reduce the overall volume, so they can indeed achieve the purpose of the novel.
