Description

Technical Field

[0001] This utility model relates to the field of chemical parameter detection, and in particular to an electrode connector and an electrode including the same. Background Technology

[0002] In the field of chemical parameter detection, electrodes are commonly used for detection. Existing electrodes transmit the measurement signal from the electrode rod via connectors. Currently, connectors primarily achieve connection through the deformation of a spring-loaded pin under pressure, which then contacts a fixed pin.

[0003] However, existing connectors use pin-type contacts, resulting in contact points that are too small. If water vapor gets in, it could cause a short circuit.

[0004] Furthermore, the retaining pins are prone to breaking off inside the holes caused by the deformation of the spring-loaded pins, and debris can easily get into the holes. This makes it inconvenient for customers to insert and remove the pins, and they may have difficulty determining the insertion angle. Excessive torque can also easily cause them to break. Moreover, due to the previously short travel of the connector's retaining pins, poor contact was common.

[0005] In view of this, the present invention relates to an electrode connector and an electrode including the same, in order to overcome the above-mentioned technical problems. Utility Model Content

The mounting holes surround the mounting cavity and communicate with the mounting cavity. The spring pieces are respectively inserted into the corresponding mounting holes, such that the arc-shaped surface of the spring pieces protrudes into the mounting cavity.

[0014] According to one embodiment of the present invention, the arcuate surface of the spring is connected side-by-side to the body of the spring via a bottom positioning part, and the width of the arcuate surface is smaller than the width of the body of the spring.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] like Figures 1 to 4 As shown, this utility model discloses an electrode, including a digital signal converter 100 and an electrode rod 200. The insertion terminal 210 of the electrode rod 200 is connected to the digital signal converter 100, transmitting the signal from the electrode rod 200 to the circuit board of the digital signal converter 100 to complete the signal transmission. The digital signal converter 100 includes a sleeve 110, a nut 120, and a circuit board assembly 130. The circuit board assembly 130 passes through the nut 120 and is installed inside the sleeve 110, thus forming a single unit. The circuit board assembly 130 includes a circuit board 131 and an electrode connector 300.

[0086] Combination Figure 5 As shown, this utility model also discloses an electrode connector 300, including a grounding protective sleeve 310, a plurality of spring pieces 320 and an inner sleeve 330. The spring pieces 320 are inserted into the inner sleeve 330, and the contact surface of the spring pieces 320 faces the inner side of the inner sleeve 330. The grounding protective sleeve 310 is sleeved on the outside of the inner sleeve 330 to form a whole.

[0087] like Figures 6 to 9 As shown, the spring clip 320 includes a main body 321, an arc-shaped surface 322, a top welding surface 323, a stepped fixing surface 324, and a bottom positioning part 325. The top welding surface 323 and the main body 321 are connected by the stepped fixing surface 324. For example, the stepped fixing surface 324 is arranged horizontally, with one end connected to the main body 321 and the other end connected to the top welding surface 323. The main body 321 and the top welding surface 323 are vertical and arranged parallel to each other. The arc-shaped surface 322 is connected to the bottom end of the main body 321 through the bottom positioning part 325, and the arc-shaped surface 322 and the main body 321 are arranged side by side, that is, the arc-shaped surface 322 is located on one side of the main body 321.

[0088] Here, the spring 320 is preferably made of a metallic material, such as a copper alloy (beryllium copper, etc.). The spring 320 needs to have excellent mechanical properties such as high strength, high elasticity, high conductivity, and fatigue resistance. Of course, the above is only one structure of the spring 320. Other spring structures (such as arc-shaped hook structures) can also be used, as long as the spring 320 and the insertion terminal 210 of the electrode rod 200 make surface contact to achieve the function of this utility model. Further details will not be elaborated here.

[0089] like Figures 10 to 12As shown, the inner sleeve 330 is preferably a cylindrical structure. The bottom of the inner sleeve 330 is open, forming an upward-facing mounting cavity 331 for mounting the insertion terminal 210 of the electrode rod 200. The inner sleeve 330 is preferably made of plastic material, such as PPS + glass fiber, requiring high insulation.

[0090] A rotation limiting rib 332 and multiple spaced positioning ribs 333 are provided on the inner side wall of the mounting cavity 331. Here, the rotation limiting rib 332 cooperates with the insertion terminal 210 of the electrode rod 200 to position the radial position of the insertion terminal 210. The positioning ribs 333 cooperate with the insertion terminal 210 of the electrode rod 200 to control the radial tightness of the insertion terminal 210 within the electrode connector 300.

[0091] Furthermore, a guide slope 3331 is provided at the end of the positioning rib 333 to facilitate the insertion of relevant insertion terminals (such as the insertion terminal 210 of the electrode rod 200). Similarly, an installation guide surface 334 is provided on the bottom inner wall of the inner sleeve 330 to facilitate the insertion of the insertion terminal 210 of the electrode rod 200 during the insertion of the electrode connector 300.

[0092] A PIN pin avoidance surface 335 is also provided on the bottom inner wall of the inner sleeve 330, which is used to avoid the PIN pin of the electrode rod 200 inserting terminal 210 when it is inserted into the inner side of the electrode connector 300, so as to make room for the elastic deformation of the spring piece 320 and facilitate signal transmission.

[0093] Additionally, a positioning boss 336 is provided on the top inner wall of the mounting cavity 331, which cooperates with the insertion terminal 210 of the electrode rod 200 to fix the axial position of the insertion terminal 210. The side of the positioning boss 336 is an inclined positioning cone surface 3361, which allows the insertion terminal 210 to be installed in the correct position during the continued insertion of the insertion terminal 210. The positioning boss 336 can fix the axial position of the insertion terminal 210 (e.g., Figure 21 (As shown).

[0094] Preferably, the inner sleeve 330 has multiple mounting holes 337 along the axial direction, such that the mounting holes 337 surround the mounting cavity 331 and communicate with the mounting cavity 331. When installing the spring piece 320, the spring piece 320 is inserted into the corresponding mounting hole 337, such that the arc-shaped surface 322 of the spring piece 320 protrudes into the mounting cavity 331. The shape of the mounting hole 337 matches the shape of the spring piece 320.

[0095] Specifically, reference Figure 5The spring clip 320 is inserted downwards along the mounting hole 337. When inserting, pay attention to the direction; the curved surface 322 should face the inside of the inner sleeve 330, until the bottom positioning part 325 engages with the positioning recess 3371 at the bottom of the mounting hole 337. Other spring clips are installed in a similar manner. The effect after the spring clip 320 is installed is as follows: Figure 19 As shown.

[0096] Preferably, the width of the arc-shaped surface 322 is smaller than the width of the main body 321 of the spring piece 320. The purpose of this design is:

[0097] 1. When the spring 320 is in the installation state, it is designed to prevent interference during the insertion of the spring 320 into the installation hole 337, thereby reducing frictional resistance and making insertion easier.

[0098] 2. When the spring contact 320 is in operation, that is, during the use of the spring contact 320, after contacting the insertion terminal 210 of the electrode rod 200, the spring contact 320 is deformed by pressure. The arc-shaped surface 322, due to the large gap between it and the side wall of the mounting hole 337, can move freely, avoiding jamming on the side wall and causing poor contact (e.g.). Figure 20 (As shown).

[0099] In this embodiment, the arc-shaped surface 322 of the spring piece 320 is designed in an arc shape, allowing it to rotate around the bottom positioning part 325 as the center. When the spring piece 320 is subjected to an upward vertical force from the insertion terminal 210 of the electrode rod 200, it rotates counterclockwise due to the pressure. Then, when the relevant connector is pulled out, the pressure disappears, and it rotates clockwise back to its initial state.

[0100] like Figures 13 to 15 As shown, the grounding protective sleeve 310 is preferably a hollow cylindrical structure that matches the shape of the inner sleeve 330. At least one positioning hole 311 is provided at the bottom outer edge of the grounding protective sleeve 310. Correspondingly, a mounting boss 338 extends outward from the bottom outer edge of the inner sleeve 330, and at least one positioning protrusion 3381 is provided on the mounting boss 338. When the grounding protective sleeve 310 is fitted onto the outside of the inner sleeve 330, the positioning hole 311 and the positioning protrusion 3381 engage with each other.

[0101] Here, the grounding protective sleeve 310 is preferably made of metal, such as stainless steel. The grounding protective sleeve 310 has sufficient strength and also provides electromagnetic shielding protection for the internal electronic signal transmission.

[0102] In addition, multiple fixing ribs 312 are provided on the top of the grounding protection sleeve 310, and a positioning groove 313 is formed between every two fixing ribs 312. The circuit board 131 of the circuit board assembly 130 is inserted into the positioning groove 313, and the top surface of the fixing rib 312 is soldered to the circuit board 131.

[0103] like Figure 15 As shown, the lower end face of the circuit board 131 is inserted into the positioning groove 313 of the grounding protective sleeve 310, and then the top surface of the fixing rib 312 is soldered to the circuit board 131. This ensures that the circuit board 131 is reliably and firmly fixed on the connector, while the electrode connector 300 and the circuit board 131 are in contact with each other, thereby ensuring the completion of the electrostatic grounding function.

[0104] Furthermore, to simplify the connection between the grounding protective sleeve 310 and the inner sleeve 330 and to increase its strength, an interference fit is employed in the design. For example, multiple side ribs 339 (e.g., cylindrical side ribs) are designed on the outer cylindrical surface of the inner sleeve 330, and the inner surface 314 of the grounding protective sleeve 310 is interference-fitted with the side ribs 339. Since the side ribs 339 are relatively small, they are preferably made of plastic, which is relatively easy to deform. During the downward movement and installation of the grounding protective sleeve 310, relevant tooling is required for pressing it in, ultimately forming a tight and secure whole. Through the interaction of the multiple cylindrical side ribs 339 and the inner surface 314 of the grounding protective sleeve 310, the relative positions of the inner sleeve 330 and the grounding protective sleeve 310 are fixed.

[0105] However, to ensure consistent installation position each time, this embodiment utilizes the positioning hole 311 of the grounding protective sleeve 310 and the positioning protrusion 3381 of the inner sleeve 330. During the downward pressing of the grounding protective sleeve 310, the positioning protrusion 3381 can precisely engage with the positioning hole 311. This completely fixes the positions of the grounding protective sleeve 310 and the inner sleeve 330. The final positional effect can be seen from [reference needed]. Figure 16 and Figure 18 As shown.

[0106] According to the above structural description, after the spring piece 320 is installed into the inner sleeve 330, the grounding protection sleeve 310 is installed. The specific process is as follows: the grounding protection sleeve 310 is placed directly above the inner sleeve 330 along its axial direction, and the radial angle is adjusted so that the positioning hole 311 of the grounding protection sleeve 310 is aligned with the positioning protrusion 3381 of the inner sleeve 330. The grounding protection sleeve 310 is then inserted vertically downwards. During the insertion process, friction and compression can be felt between the cylindrical side rib 339 and the inner side surface 314 of the grounding protection sleeve 310.

[0107] Furthermore, the electrodes require high insulation during signal transmission. In particular, such as... Figure 16The multiple spring contacts 320 on the electrode connector 300 shown need to meet insulation requirements. Therefore, in this embodiment, a ring of insulating adhesive 400 is applied to the top of the electrode connector 300, i.e., the top surface of the inner sleeve 330. The insulating adhesive 400 is preferably epoxy resin insulating adhesive, which has good insulation performance, as well as good fixing and sealing performance.

[0108] Preferably, the insulating adhesive 400 is evenly applied to the top surface of the inner sleeve 330, and simultaneously fills the gap between the spring contact 320 and the mounting hole 337. This gap is a deliberately reserved gap for adhesive application. The purpose of this reserved gap is twofold: first, to facilitate the insertion of the spring contact 320 into the mounting hole 337 (the gap makes insertion easier); second, to better encapsulate the spring contact 320 with the insulating adhesive 400, ensuring insulation performance.

[0109] like Figure 16 As shown, the stepped fixing surface 324 on the spring contact 320, during the aforementioned application of insulating adhesive, is equivalent to a small groove. This area is filled with adhesive, preventing the spring contact 320 from popping out and thus effectively and reliably fixing its position. Simultaneously, due to the filling with insulating adhesive 400, the top of the electrode connector 300 is completely sealed, providing excellent sealing performance. The function of the insulating adhesive here is to fix, seal, and insulate.

[0110] Furthermore, such as Figure 21 Combination Figure 3 As shown, the grounding protective sleeve 310 is also provided with a first end face 315 and a second end face 316. The first end face 315 contacts the relevant inner surface of the sleeve 110, which can axially position the circuit board assembly 130. Preferably, since the inner side of the sleeve 110 is made of metal, the first end face 315 of the grounding protective sleeve 310 contacts it, which serves as grounding and can discharge static electricity. When the electrode rod is tightened, the second end face 316 contacts the top surface of the inner metal side of the nut 120, which fixes the axial position of the nut 120 and also serves as static grounding.

[0111] Based on the above structural description, the electrode connector of this utility model has safety, reliability, and grounding protection functions. The spring contact is mechanically positioned and glued to the inner sleeve, and the grounding protection sleeve covers the inner sleeve, forming a whole. The electrode connector plays a connecting role; its upper end is fixed to the circuit board assembly, providing fixation and support. Its lower end is effectively and reliably connected to the electrode rod, transmitting the signal from the electrode rod to the circuit board via the spring contact, thus completing the signal transmission function.

[0112] In summary, the electrode connector and its included electrode of this utility model adopt a spring-loaded electrode connector structure, which achieves an effective and reliable connection between the lower end of the connector and the electrode rod. The spring-loaded contact transmits the signal from the electrode rod to the circuit board, thus completing the signal transmission function. The entire structure ensures that the electrode rod surface is under pressure, maintains contact for a long time, and is simple, efficient, and highly reliable.
