[0040] In view of the deficiencies in the prior art, the inventor of this case has proposed the technical solution of the utility model after long-term research and extensive practice. The technical solution, its implementation process and principle will be further explained as follows.

[0041] In existing electrical connection modules, due to the electric and thermal coupling generated by the power lines, the temperature will accumulate and exceed the operating temperature of the power lines. This will not only affect the performance of the electrical connection module, but may even burn out the module.

[0042] Please see Figure 1-Figure 3 , a multi-channel electrical connection module, comprising: a plurality of single-channel electrical connection modules, an insulating component;

[0043] The single-channel electrical connection module comprises: an electrical line 10 , a first connection terminal 1 , a second connection terminal 9 , an elastic member, a power pin, and a housing 4 .

[0044] The two ends of the electrical wire 10 are electrically connected to the first connection terminal 1 and the second connection terminal 9 respectively. The power pin is arranged in the second assembly hole at least together with the end of the second connection terminal away from the electrical wire. An anti-slip member is arranged on the second connection terminal 9 for fixing the second connection terminal 9 and the power pin; a fixing member is arranged on the second connection terminal 9 for fixing the second connection terminal 9 to the second assembly block 7. An anti-rotation member is arranged on the first connection terminal 1 for fixing the first connection terminal 1 to the first assembly block 3. An anti-rotation key is arranged inside the cavity of the housing 4; the multiple single-channel electrical connection modules and the insulating components are installed in the housing 4.

[0045] The insulating assembly comprises a first assembly block 3, a second assembly block 7, a third assembly block 8, a plurality of radial insulating parts, and a plurality of axial insulating parts which are separately arranged.

[0046] The first assembly block 3 is provided with a plurality of first assembly holes distributed at intervals, the second assembly block 7 is provided with a plurality of second assembly holes distributed at intervals, at least the first connecting terminal 1 is provided in the first assembly hole, at least the second connecting terminal 9 is provided in the second assembly hole, and the plurality of electrical wires 10 are spaced apart from each other.

[0047] In the first assembly hole of the first assembly block 3, one end of the first connection terminal 1 is connected to the electrical wire 10, and the other end is connected to the elastic member. In the chamber of the third assembly block 8, the other end of the electrical wire 10 is connected to one end of the second connection terminal 9. In the chamber of the second assembly block 7, the other end of the second connection terminal 9 is connected to the power pin.

[0048] The radial insulating member has a cavity inside for wrapping the electrical wire 10. The axial insulating member has multiple holes for passing the electrical wire 10. It should be noted that the first assembly block 3 is connected to the radial insulating member, and the third assembly block 8 is connected to the radial insulating member. After confirming that both ends are radial insulating members, the axial insulating member and the radial insulating member are alternately connected in sequence between the first assembly block 3 and the third assembly block 8.

[0049] Please see Figure 4 , the first connecting terminal 1 is provided with openings at both ends, which are threaded holes and threading holes respectively. It should be noted that in order to facilitate the connection of the power cord, the threaded holes and threading holes here are not through. The electrical wire 10 enters from the threading hole and is fixedly connected in the threading hole. The specific connection method includes but is not limited to welding. An anti-rotation part is provided on the outer surface of the first connecting terminal 1, including but not limited to straight knurling, which is used to fix the first connecting terminal 1 to the first assembly block 3. The outer surface of the first connecting terminal 1 is also provided with side holes. The side holes here can be understood as electroplating process holes, which can avoid blackening in the holes during electroplating.

[0050] Exemplarily, the electrical line 10 may be a power line, a cable, or the like.

[0051] Please see Figure 5 The first assembly block 3 is provided with a plurality of first assembly holes spaced apart, similar to a honeycomb briquette shape. One end of the first connection terminal 1 with a threaded hole enters and is fixed in the chamber of the first assembly block 3. The straight knurling provided on the outer surface of the first connection terminal 1 can prevent the first connection terminal 1 from slipping in the first assembly block 3, thereby improving stability.

[0052] The outer circumferential surface of the first assembly block 3 is also provided with a groove for preventing the first assembly block 3 from rotating radially.

[0053] Please see Figure 6, the elastic member is arranged in the first assembly hole at least with the end of the first connecting terminal 1 away from the electrical wire 10. The elastic member can be an elastic pin 2. The elastic pin 2 has an external thread for matching the threaded hole of the first connecting terminal 1. It can be understood that rigid contact is prone to jump between the contact state and the non-contact state, which is not very stable. In this embodiment, the elastic pin 2 is mainly used to achieve axial elastic floating contact to avoid large tolerance. Note that the elastic member here includes but is not limited to the elastic pin 2, and any elastic member with elastic expansion and contraction can be used.

[0054] Please see Figure 7 , an anti-slip part is provided on the second connection terminal 9, including but not limited to straight knurling, for preventing the second connection terminal 9 and the power pin from rotating. A fixing part is also provided on the second connection terminal 9, including but not limited to a fixing ring, for fixing the second connection terminal 9 to the second assembly block 7. The electrical wire 10 is inserted from the side close to the fixing ring and fixed in the second connection terminal 9. Specifically, the second connection terminal 9 can be understood as a power terminal socket. The second connection terminal 9 includes a power pin socket. The power pin includes but is not limited to a banana plug.

[0055] Please see Figure 8 The second assembly block 7 is provided with a plurality of second assembly holes spaced apart, similar to a honeycomb briquette shape. The power supply needle is arranged in the chamber of the second assembly block 7. The outer circumferential surface of the second assembly block 7 is provided with a groove for preventing the second assembly block 7 from rotating radially.

[0056] In another embodiment of the present application, the insulating component also includes a third assembly block 8 and a fourth assembly block, the third assembly block 8 is provided with a plurality of third assembly holes distributed at intervals, the portion of the electrical wire 10 close to the second connecting terminal 9 is arranged in the third assembly hole, and the fourth assembly block is provided with a plurality of fourth assembly holes distributed at intervals, the portion of the electrical wire 10 close to the first connecting terminal 1 is arranged in the fourth assembly hole.

[0057] Preferably, the third assembly block 8 and the second assembly block 7 are clearance-fitted; and the fourth assembly block and the first assembly block 3 are clearance-fitted.

[0058] Please see Fig. 9 The third assembly block 8 is provided with a plurality of third assembly holes spaced apart from each other, similar to a honeycomb briquette shape. The outer circumferential surface of the third assembly block 8 is provided with a groove for avoiding the key position of the housing 4. It can be understood that when the second connection terminal 9 is connected to the second assembly block 7, the axial tension of the second connection terminal 9 is lacking. Therefore, the third assembly block 8 here is for axially fixing the second connection terminal 9 to increase the axial fixity.

[0059] Likewise, a fourth assembly block may also be provided to increase axial fixity.

[0060] Please see Fig.10 The insulating assembly also includes a plurality of radial insulators, each of which is coated on the surface of an electrical wire 10, and the radial insulators are connected to the first assembly block 3 and the second assembly block 7; the radial insulators include an insulating tube 6, which is sleeved on the outside of the electrical wire.

[0061] Please see Fig.11 The insulating assembly also includes an axial insulator. A plurality of insulating tubes 6 are provided on each of the electrical wires 10. The plurality of insulating tubes 6 and the plurality of axial insulators matching one electrical wire 10 are alternately arranged in sequence along the length direction of the electrical wire 10.

[0062] The axial insulating member is a spacer 5. The spacer 5 has multiple holes for allowing the electrical wire 10 to pass through.

[0063] It should be noted that the outer diameter of the insulating tube 6 is larger than the aperture of the through hole of the isolation plate 5. The outer diameter of the insulating tube 6 is larger than the cavity diameter of the first assembly block 3 and the second assembly block 7. At this time, the first assembly block 3 is connected to the insulating tube 6, and the third assembly block 8 is connected to the insulating tube 6. After determining that both ends are insulating tubes 6, between the first assembly block 3 and the third assembly block 8, the isolation plate 5 and the insulating tube 6 are alternately connected in sequence. In a specific embodiment, the electrical wire 10 passes through the insulating tube 6 and the isolation plate 5, and the end face of the insulating tube 6 is against the surface of the isolation plate 5, but a small amount of gap is reserved, which can rotate freely and slide a small amount in the axial direction. This can avoid axial assembly interference of parts.

[0064] It is understandable that the fewer the number of layers of the insulating tube 6, the longer the length of the insulating tube 6, and the greater the difficulty of processing and manufacturing. At the same time, the more layers there are, the more corresponding isolation plates 5 and insulating tubes 6 will become redundant. In a specific embodiment of the present application, the isolation plates 5 can be set to 4, axially separating the insulating tube 6 into 5 layers. There are 3 insulating tubes 6 per layer. 3 can provide stable support. It should be noted that the insulating tube here is not necessarily set according to the number of holes of the assembly hole, and only one can be set, which is not limited here.

[0065] The outer surface of the isolation sheet 5 is also provided with a groove for avoiding the key position of the housing 4 .

[0066] Please see Figure 12-13The shell 4 has a chamber. The multiple single-channel electrical connection modules and insulating components are arranged in the chamber. Anti-rotation key positions are set on both sides of the interior of the chamber of the shell 4 to prevent the first assembly block 3 and the second assembly block 7 from rotating. In the figure, two anti-rotation key positions are set on each side. Specifically, one or three or more anti-rotation key positions can also be set. The shell 4 here can be understood as an RF feed shell 4. A circular ring groove is set on the outer surface of the shell 4 to prevent the shell 4 from rotating radially, so that the multi-channel electrical module is better fixed.

[0067] A heat shrink tubing is provided between the first connection terminal 1 and the electrical wire 10 .

[0068] In this embodiment, the assembly sequence of the single-channel electrical connection module is as follows:

[0069] First, weld the two sides of the electrical wire 10 to the first connection terminal 1 and the second connection terminal 9 respectively;

[0070] Press the second connecting terminal 9 into the second assembly block 7;

[0071] Insert the third assembly block 8 and connect it to the second connection terminal 9;

[0072] The insulating tube 6 and the spacer 5 are alternately installed into the electrical wire 10;

[0073] Press the single-channel electrical connection module into the housing 4 from the housing 4B port to the housing 4A port;

[0074] Press the first assembly block 3 from the port of the housing 4A toward the housing 4B;

[0075] The elastic needle 2 is screwed into the first assembly block 3 .

[0076] The assembly sequence of the multi-channel electrical connection module is as follows:

[0077] First, the two sides of the plurality of electrical wires 10 are respectively welded to the plurality of first connection terminals 1 and the plurality of second connection terminals 9;

[0078] Pressing a plurality of second connecting terminals 9 into the second assembly block 7;

[0079] Insert the third assembly block 8 and connect it to the second connection terminal 9;

[0080] Multiple insulating tubes 6 and multiple isolation sheets 5 are alternately installed into the electrical wire 10 in sequence;

[0081] Press multiple single-channel electrical connection modules into the housing 4 from the housing 4B port to the housing 4A port;

[0082] Press the first assembly block 3 from the port of the housing 4A toward the housing 4B;

[0083] A plurality of elastic needles 2 are screwed into the first assembly block 3 .

[0084] In this embodiment, the first assembly block 3 and the second assembly block 7 are both provided with 24 holes. The number of holes in the present application is not limited to 24. It is understandable that the number of holes is pre-set according to the actual application, and the GND position is also pre-set. The number of holes will generate thermoelectric coupling, and the more holes, the hotter it is.

[0085] Hole 1-2, 208V power supply line, current 17AMAX, cable specification 2.5mm2;

[0086] Hole 3-10, 208V power supply line, current 11AMAX, cable specification 1.5mm2;

[0087] Hole position 11-23, 48V power supply line, current 8AMAX, cable specification 1.0mm2;

[0088] Hole position 24, GND, cable specification 1.5mm2.

[0089] A heat shrink sleeve is added to the welding tail of hole positions 1-10 of the first assembly block 3. The heat shrink sleeve is sleeved with the first connection terminal 1 and the electrical wire 10. After the welding tail of the first terminal 1 and the electrical wire 10 are protected by the heat shrink sleeve, the insulation protection strength with the adjacent terminal and the housing 4 can be increased.

[0090] The withstand voltage requirement of the hole positions 1-10 relative to the adjacent hole positions 11-20 and the first connection terminal 1 is: withstand voltage 250V, 15S.

[0091] For example, the withstand voltage requirement of hole 1 relative to hole 11, 20 and the first connection terminal 1 is: withstand voltage 250V, 15S.

[0092] The voltage resistance requirement is set here for test prevention to avoid adjacent holes with unqualified voltage resistance flowing into the client.

[0093] The length of the power line can be set to: 272±1. The length of the leaking part at both ends of the power line is: 4±0.5. The length of the elastic needle leaking out of the first assembly block can be: 2.8±0.25. The length between the elastic needle and the first assembly block is: 0.8±0.20. The length of the power pin socket in the second assembly block can be: 2.25-0.10~2.25+0.05.

[0094] Note that the above dimensions refer to ISO-2768-m.

[0095] It should be understood that the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model.
