[0077] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0078] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Preferred embodiments of the present invention will now be described in detail, examples of which are shown in the drawings. Wherever possible, the same reference numerals will be used in all the drawings to denote the same or similar parts.

[0079] Furthermore, although the terminology used in this invention is selected from commonly known and used terms, some terms mentioned in this specification may have been selected by the applicant in his or her judgment, and their detailed meanings are explained in the relevant sections of the description herein.

[0080] Furthermore, it is required that this utility model be understood not only through the actual terminology used, but also through the meaning implied by each term.

[0081] like Figure 1 and Figure 2 As shown, this utility model discloses an electrode, including a digital protection converter 10 and an electrode rod 20, wherein the electrode rod 20 is interconnected with the digital protection converter 10. The electrode rod 20 is the type of electrode rod disclosed in this utility model.

[0082] like Figure 3 and Figure 4 As shown, the electrode rod 20 includes an electrode rod connecting assembly 30, a protective sleeve 40, and an electrode tube 50. The protective sleeve 40 is fitted over the outside of the electrode rod connecting assembly 30, and the electrode tube 50 is inserted into the electrode rod connecting assembly 30.

[0083] like Figures 5 to 12 As shown, the electrode rod connecting assembly 30 is an electrode rod connecting assembly disclosed in this utility model, including a male head 31, a snap-fit ​​assembly 32, and a base 33. Here, the snap-fit ​​assembly 32 is preferably a hollow columnar structure. At the first end of the snap-fit ​​assembly 32 (e.g., Figures 7 to 9 At least one first limiting boss 322 is provided on the inner wall surface 321 of the upper end shown. Correspondingly, at least one first positioning groove 312 is provided on the connecting end 311 of the male connector 31 (e.g., Figure 10 (On the annular surface shown). The first limiting boss 322 engages in the first positioning groove 312, so that the inner wall surface 321 of the first end of the buckle assembly 32 fits against the connecting end 311 of the male head 31.

[0084] Similarly, at least one second limiting protrusion 324 is provided on the inner wall surface 323 of the second end of the buckle assembly 32. Correspondingly, the base 33 has a hollow cylindrical structure, and at least one second positioning groove 332 (e.g., ...) is provided on the connecting end 331 of the base 33. Figure 11 As shown), the second limiting boss 324 is engaged in the second positioning groove 332, so that the inner wall surface 323 of the second end of the buckle assembly 32 fits against the connecting end 331 of the base 33.

[0085] In this application, the snap-fit ​​assembly 32 may include at least two snap-fit ​​members, and the two adjacent snap-fit ​​members are snap-fit ​​connected and fixed.

[0086] Alternatively, more preferably, for example, in this embodiment... Figure 8 and Figure 9 As shown, the latching assembly 32 includes a first latching member 325 and a second latching member 326. One side of the first latching member 325 and one side of the second latching member 326 are rotatably connected to each other, and the other sides of the first latching member 325 and the second latching member 326 are interlocked. For example, on the other side of the first latching member 325 (i.e....) Figure 7 The left end face C shown in the diagram is provided with an outwardly extending locking boss 327, and the locking boss 327 is provided with a positioning hole 3271. The other side of the second fastener 326 (i.e. Figure 7The right end face D shown in the figure has a recessed clearance surface 328, and a raised rib 329 is provided on the clearance surface 328. When the first fastener 325 and the second fastener 326 are engaged with each other, the positioning hole 3271 of the locking boss 327 is locked with the raised rib 329.

[0087] In this embodiment, one side of the first fastener 325 and one side of the second fastener 326 are rotatably connected by a connecting part 60. Here, the connecting part 60 can be configured as a rotating shaft, or preferably a plate-like structure (e.g., Figure 8 and Figure 9 As shown), the first fastener 325 and the second fastener 326 rotate relative to the connecting part 60.

[0088] like Figure 8 and Figure 9 As shown, the snap-fit ​​assembly 32 is in its initial, unbent state. Because it requires good plastic deformation capability, the snap-fit ​​assembly 32 is preferably made of plastic material. Furthermore, it needs to be transparent to clearly see if the internal welding wires are correct. Therefore, the snap-fit ​​assembly 32 can preferably be made of PC material.

[0089] Furthermore, a perforated hole 61 can preferably be provided on the connecting part 60. For example, the hole 61 is provided in the middle part of the connecting part 60. The main function of the hole 61 is to reduce the rigidity of the connecting part 60, so that the first fastener 325 and the second fastener 326 can rotate around the connecting part 60 more easily and conveniently, thereby reducing the resistance to rotation.

[0090] like Figure 10 As shown, the bottom of the male connector 31 has multiple pins 313, to which relevant signal transmission lines are soldered. Combined with... Figure 11 As shown, when the electrode rod connection assembly is in the initial assembly state, prepare the soldered wire male connector 31, the snap-fit ​​assembly 32, and the base 33, and assemble the snap-fit ​​assembly 32 as shown. Figure 11 The positions are arranged in preparation for assembly. The upper first limiting boss 322 (e.g., four in this embodiment) is engaged into the corresponding first positioning groove 312. At this time, the inner wall surface 321 of the first end of the latching assembly 32 holds the connecting end 311 of the male connector 31 (… Figure 11 The two are enclosed by a torus (the center of which is concentric and in contact with each other).

[0091] Then, the uppermost second limiting boss 324 of the plurality of second limiting bosses 324 (for example, four in this embodiment) is inserted into the corresponding second positioning groove 332. At this time, the inner wall surface 323 of the second end of the latching assembly 32 covers the outer side of the connecting end 331 of the base 33, and the two are concentric and in contact with each other. Here, the shape of the second limiting boss 324 and the structure of the first limiting boss 322 can be set to be the same.

[0092] like Figure 12 As shown, when the electrode rod connecting assembly is in the intermediate assembly state, the operator holds the structure, ensuring that the male head 31, base 33, and half of the snap-fit ​​assembly 32 are properly engaged, and then rotates the other half of the snap-fit ​​assembly 32 around the connecting part 60 by hand, so that the remaining first limiting protrusions 322 are engaged into the corresponding first positioning grooves 312, and the remaining second limiting protrusions 324 are engaged into the corresponding second positioning grooves 332, completing the assembly as shown. Figure 13 As shown.

[0093] When it is necessary to disassemble the electrode rod connecting assembly 30, simply remove the locking boss 327 of the latching assembly 32 from the clearance surface 328. The disassembly process is the reverse of the assembly process, that is, the first latching member 325 is rotated around the connecting part 60. This structural design facilitates disassembly and also makes it easier for the service team to carry out maintenance.

[0094] like Figure 14 As shown, to prevent rotation, the sides of the first limiting boss 322 and the second limiting boss 324 are set as inclined surfaces. The sides of the multiple first limiting bosses 322 are set as inclined surfaces and are fitted to the inner wall surfaces of the multiple first positioning grooves 312. The sides of the multiple second limiting bosses 324 are set as inclined surfaces and are fitted to the inner wall surfaces of the multiple second positioning grooves 332. In this way, the electrode rod connecting assembly can be positioned in the radial direction together.

[0095] Of course, the shapes of the first limiting boss 322, the second limiting boss 324, the first positioning groove 312, and the second positioning groove 332 in this embodiment are not limited to the inclined surface structure described above, and can also be other structures. For example, the limiting boss can be set to other shapes, and the positioning groove only needs to change with the shape of the limiting boss. The technical solution of this application only needs to ensure that the two can be interlocked to prevent rotation.

[0096] Combination Figures 15 to 17 As shown, the end face 314 of the male head 31 and the end face A of the first end of the snap fastener 32 are in contact with each other, and the end face 333 of the base 33 and the end face B of the second end of the snap fastener 32 are in contact with each other. In this way, the electrode rod connection assembly can be positioned in the axial direction together.

[0097] Meanwhile, during the rotation of the first latch 325, a locking mechanism will function. For example... Figure 8 and Figure 9 As shown, during rotation, the locking boss 327 comes into contact with the raised rib 329, causing plastic deformation of the part. The locking boss 327 continues to move forward, allowing the raised rib 329 to fit precisely into the positioning hole 3271. At this point, the locking boss 327 also reaches the area of ​​the clearance surface 328. The other side 325 of the first latching member 325 and the second latching member 326 also come into contact with each other, positioning them. Thus, the position of the latching assembly 32 is fixed.

[0098] Combination Figures 15 to 18 As shown, according to the above description, after the electrode rod connecting assembly 30 is assembled, it is only assembled and positioned by the snap-fit ​​assembly 32. To further improve the robustness of the connection structure, a protective sleeve 40 is fitted over the electrode rod connecting assembly 30. This effectively prevents the snap-fit ​​assembly 32 of the electrode rod connecting assembly 30 from loosening, thus increasing reliability.

[0099] Furthermore, the inner part of the protective jacket 40 is made of metal, which provides electromagnetic shielding for the signal transmission of the relevant PIN pins and soldering wire harness inside the electrode rod connection assembly 30. The outer part of the protective jacket 40 is made of plastic, meeting aesthetic requirements. The protective jacket 40 also provides waterproof and dustproof sealing protection for the electrode rod connection assembly 30. After the protective jacket 40 is installed on the electrode rod connection assembly 30, sealant is applied to the outer cylindrical surface 334 of the base 33 (in conjunction with...). Figure 16 (As shown). For example, at least one groove 335 is formed on the outer cylindrical surface 334, and a large amount of sealant is filled in the groove 335 to make the connection between the electrode rod connecting assembly 30 and the protective jacket 40 more reliable and secure.

[0100] Furthermore, such as Figure 18 As shown, the electrode tube 50 is assembled after the electrode rod connecting assembly 30 and the protective sleeve 40 are assembled. The inner wall surface of the base 33 of the electrode rod connecting assembly 30 includes a guide slope 336 connected from the outside to the inside and an inner surface 337 (combined with...). Figure 16 As shown, the electrode tube 50 is inserted into the base 33 along the guide slope 336, making the insertion of the electrode tube 50 convenient and easy. After being inserted into the relevant position, sealant is applied around the inner side 337 to secure the electrode tube 50 and the electrode rod connecting assembly 30 firmly.

[0101] In summary, this utility model's electrode rod connecting assembly and the electrode rod and electrode included therein optimize the traditional one-piece structure of the electrode rod into a quick-assembly and disassembly structure that connects the male connector and the base via snap-fit. It achieves rapid installation and removal of the male connector and the base through snap-fit.

[0102] The electrode rod connection assembly can be quickly assembled and disassembled, which is convenient for operation, improves the reliability of the electrode rod, and reduces maintenance costs.
