Description

[Technical Field]

[0001] The present invention relates to a noise-proof electrode connector, and more particularly to an electrode connector with noise-proof function, which can isolate external interference, and is used, for example, in the medical field to detect human biosignals. [Background technology]

[0002] Medical electrode patches are used to detect various electrical signals from the body, such as in electrocardiograms. However, because the electrical signals from the heart are very weak, the measurement process is easily affected by external interference, such as static electricity.

[0003] Therefore, how to improve the noise prevention effect of electrode connectors through improved structural design and overcome the above-mentioned deficiencies is a problem to be solved in this technical field. Summary of the Invention [Problem to be solved by the invention]

[0004] The technical problem that the present invention aims to solve is to address the shortcomings of existing technologies by providing an electrode connector with noise prevention capabilities, thereby avoiding interference from the outside world. [Means for solving the problem]

[0005] To solve the above technical problems, one technical solution adopted by the present invention is to provide a noise-proof electrode connector, which includes a conductor, an electrode clip, an inner insulating layer, a noise-proof layer, and an outer insulating layer. The conductor includes a conductive core wire, an insulator, a metal shield, and a cable cover, where the insulator surrounds the conductive core wire, the metal shield is positioned around the insulator, and the cable cover surrounds the metal shield. The metal shield has an exposed section that extends beyond the cable cover. The conductive core wire has an exposed connection section that extends beyond the insulator. The connection section is connected to the top surface of the electrode clip. The inner insulating layer surrounds the electrode clip. The noise-proof layer surrounds the inner insulating layer and the exposed section of the metal shield. The outer insulating layer surrounds the noise-proof layer and is connected to the cable cover of the conductor.

[0006] In order to solve the above technical problems, another technical solution of the present invention is to provide a method for manufacturing a noise-proof electrode connector, which method includes at least the steps of providing an electrode clip, providing a conductor wire, the conductor wire including a conductive core wire, an insulator, a metal shield, and a cable cover, the insulator surrounding the conductive core wire, the metal shield surrounding the insulator, and the cable cover surrounding the metal shield, allowing the metal shield to extend beyond the cable cover to form an exposed section, allowing the conductive core wire to extend beyond the metal shield to form an exposed connection section, connecting the connection section to a top surface of the electrode clip, forming an inner insulating layer and enclosing the electrode clip, forming a noise-proof layer and enclosing the inner insulating layer and the exposed section of the metal shield, and forming an outer insulating layer, enclosing the noise-proof layer, and connecting the outer insulating layer to the cable cover of the conductor wire.

[0007] One beneficial effect of the present invention is that the noise-proof electrode connector provided by the present invention connects the connection section to the top surface of the electrode clip, and the noise-proof layer wraps the exposed section of the metal shield, thereby achieving the noise-proof effect of the electrode connector and avoiding electrostatic interference from the external environment.

[0010] The following describes the embodiments of the present invention. Those skilled in the art can understand the merits and advantages of the present invention from the disclosure of this specification. The present invention can be implemented or applied in other different embodiments. Each detail in this specification can also be modified and changed equivalently based on various aspects or applications without departing from the spirit of the present invention. In addition, the drawings of the present invention are for simple and schematic illustration only and do not represent actual dimensions. The following embodiments will further explain the technical matters related to the present invention, but the disclosed contents do not limit the present invention. In addition, the term "or" used in this specification may include any one or more combinations of related items according to actual circumstances.

[0011] [First embodiment] 1 to 4, a first embodiment of the present invention provides a noise-proof electrode connector including a conductive wire 10, an electrode clip 20, an inner insulating layer 30, a noise-proof layer 40, and an outer insulating layer 50. The electrode clip 20 is used to clip a conductive male buckle 92 of a conductive patch 9. For example, the present invention is applicable to conductive patches 9 for electrocardiograms (ECG), electromyograms (EMG), and electroencephalograms (EEG), but is not limited thereto. In the conductive patch 9, a gel zone 94 is located below the conductive male buckle 92 and the outer surface layer 93, and the conductive male buckle 92 is electrically connected to the gel zone 94.

[0012] The conductor 10 is a type of electrical cable that can resist interference. Specifically, the conductor 10 includes a conductive core wire 11, an insulator 11C, a metal shield 12, and a cable cover 13. The insulator 11C encases the conductive core wire 11, and is, for example, a plastic insulating layer. The metal shield 12 is positioned around the insulator 11C. The cable cover 13 encases the metal shield 12.

[0013] The metal shield 12 can be formed by braiding or winding multiple metal wires, such as copper wires. Alternatively, a metal film, such as aluminum Mylar foil, can be wrapped around the outside of the insulator 11C. In this embodiment, the metal shield 12 has an exposed section 12E, which is the portion not covered by the cable cover 13. The exposed section 12E extends beyond the cable cover 13 in its longitudinal direction. The conductive core wire 11 has a connection section 11E exposed beyond the metal shield 12 in its longitudinal direction, and the connection section 11E is attached to the top surface of the electrode clip 20. The connection section 11E is welded to the top surface of the electrode clip 20, but the connection method of the present invention is not limited to this and can be, for example, soldering, spot welding, or crimping.

[0014] Preferably, the conductor 10 of this embodiment also includes a second shield 12C with an insulating function. The second shield 12C is a conductive shield layer separate from the metal shield 12, such as aluminum foil or a carbon tube. The second shield 12C is preferably a carbon tube, or it can be referred to as a conductive carbon inner shield layer. The conductive carbon inner shield layer further encases the insulator 11C, and the metal shield 12 encases the conductive carbon inner shield layer. This further improves the noise prevention effect. Specifically, the second shield 12C is positioned between the metal shield 12 and the insulator 11C and is configured to extend beyond the metal shield 12 in the longitudinal direction. A portion of the second shield 12C is exposed on the surface of the insulator 11C and contacts the noise prevention layer 40. However, the present invention is not limited to a conductor having two shield layers. The conductor of the present invention may also have a single shield layer, for example, consisting of only the metal shield 12.

[0015] In this embodiment, the exposed section 12E is formed so that the multiple metal wires of the metal shield 12 extend beyond the cable cover 13 in the longitudinal direction and then bend in the reverse direction. In other words, these metal wires are folded back in the direction away from the electrode clip 20, and the exposed section 12E wraps around the front end portion of the cable cover 13. However, the present invention is not limited to this.

[0016] Furthermore, the noise-preventing electrode connector of the present invention also includes a metal ring 15. The metal ring 15 holds the exposed section 12E of the metal shield 12. Specifically, the metal ring 15 presses and fixes the exposed section 12E of the metal shield 12 to the cable cover 13. The metal ring 15 in this embodiment is annular, and the width of the metal ring 15 is equal to or less than the length of the exposed section 12E. In other words, the metal ring 15 does not completely cover the exposed section 12E.

[0017] An inner insulating layer 30 encases the electrode clip 20. In this embodiment, the inner insulating layer 30 is insert molded with a plastic insulating material, although the present invention is not limited thereto.

[0018] One of the features of this embodiment is the provision of a noise prevention layer 40. The noise prevention layer 40 encases the inner insulating layer 30, the exposed section 12E of the metal shield 12, and the metal ring 15. The noise prevention layer 40 is made of a conductive material, such as a metal material or a conductive plastic. Examples of conductive plastic include polyvinyl chloride (PVC), polypropylene (PP), acrylonitrile butadiene styrene (ABS), nylon, and polycarbonate (PC). These materials are injection-molded onto the outer layer of the inner insulating layer 30. More specifically, the layer is manufactured by insert molding, although the present invention is not limited to this material and manufacturing method. For example, spraying or printing conductive ink, attaching metal or conductive tape, or assembling other conductive materials may also be used.

[0019] Furthermore, the noise prevention layer 40 of this embodiment extends beyond the bottom surface of the electrode clip 20 to form a circular flange 43, as shown in FIG. 1 . The range of the flange 43 preferably completely covers the gel zone 94 of the conductive patch 9. The gel zone 94 is the portion that actually contacts the skin and acquires a signal. In other words, the radius of the flange 43 is equal to or greater than the radius of the gel zone 94. However, the present invention is not limited to this, and the flange 43 may be omitted. Here, the orthographic area (or the area it covers) of the noise prevention layer 40 is equal to or greater than the area of ​​the gel zone 94 of the conductive patch 9. In this way, the noise prevention layer 40 isolates the electrode clip 20 from external electrostatic interference and achieves its noise prevention function.

[0020] In this embodiment, the anti-noise layer 40 also surrounds the metal ring 15. The metal ring 15 can increase the contact position and area with the anti-noise layer 40, and the protruding structure of the metal ring 15 can enhance the bonding strength between the anti-noise layer 40 and the conductor 10. During the process of forming the anti-noise layer 40 by embedding injection molding, the metal ring 15 can firmly fix the metal shield 12 of the conductor 10.

[0021] The outer insulating layer 50 covers the noise prevention layer 40 and the cable cover 13 of the conductor 10. The outer insulating layer 50 can be formed by injection molding an insulating material. More specifically, the outer insulating layer 50 of this embodiment can be formed by insert molding technology. However, the present invention is not limited thereto.

[0022] As shown in Figures 2 and 3, in this embodiment, the inner insulating layer 30, the noise prevention layer 40, and the outer insulating layer 50 have a waterdrop shape when viewed from above. See also Figure 4. The inner insulating layer 30 includes a first extension 32, the noise prevention layer 40 includes a second extension 42, and the outer insulating layer 50 includes a third extension 52. The first extension 32 slightly encloses the folded-back portion of the exposed section 12E, while the second extension 42 is larger than the first extension 32 and encloses most of the exposed section 12E. The second extension 42 is located on the outer periphery of the electrode clip 20 and encloses the metal ring 15. The third extension 52 encloses the outer periphery of the conductive wire 10. Due to the above-mentioned structural arrangement, the shield structure of this embodiment is very stable during the injection molding process, and both ends of the exposed section 12E are firmly fixed, ensuring complete connection and conduction between the metal shield 12 and the noise prevention layer 40.

[0023] The present invention also provides a method for manufacturing a noise-proof electrode connector, as shown in Figures 1 to 4. The method includes at least the following steps:

[0024] The method includes providing an electrode clip (20).

[0025] This is followed by the step of providing a conductor 10. The conductor 10 includes a conductive core wire 11, an insulator 11C, a metal shield 12, and a cable cover 13. The insulator 11C encases the conductive core wire 11, the metal shield 12 is positioned around the insulator 11C, and the cable cover 13 encases the metal shield 12.

[0026] This is followed by the step of causing the metal shield 12 to extend beyond the cable cover 13 to form an exposed section 12E.

[0027] This is followed by the step of causing the conductive core wire 11 to extend beyond the metal shield 12 to form an exposed connection section 11E.

[0028] This is followed by the step of connecting the connection section 11E to the top surface of the electrode clip 20.

[0029] This is followed by the step of forming an inner insulating layer 30 to encase the electrode clip 20 .

[0030] This is followed by forming a noise prevention layer 40 to encase the inner insulating layer 30 and the exposed section 12E of the metal shield 12.

[0031] The subsequent step includes forming an outer insulating layer 50 to encase the noise prevention layer 40 and connect it to the cable cover 13 of the conductor 10 .

[0032] The above-described manufacturing method of the present invention can be formed using insert molding technology, and its advantage is that the anti-noise layer 40 is simultaneously formed between the inner insulating layer 30 and the outer insulating layer 50 during the injection molding process, thereby improving the integrated, stable, and durable quality of the electrode connector and reducing the space required for mechanisms that require an assembled case and the possibility of assembly parts separating after long-term use. However, the above is merely one preferred embodiment of the present invention, and the forming method of the present invention is not limited to this.

[0033] [Second embodiment] As shown in FIG. 5, this embodiment differs from the above-described embodiment in that the exposed section 12E of the metal shield 12 is not folded back. The exposed section 12E can be a plurality of metal wires, a metal layer, a carbon tube, or a combination thereof. Here, the exposed section 12E of the metal shield 12 passes through the second extension 42 of the noise prevention layer 40 via the outer insulating layer 50 and extends to the inner insulating layer 30. Additionally, the metal ring 15 can be omitted.

[0034] [Beneficial Effects of the Embodiments] One beneficial effect of the present invention is that the noise-proof electrode connector provided by the present invention can improve the shielding effect of the electrode connector and avoid electrostatic interference from the outside world through technical means such as the connection section being connected to the top surface of the electrode clip, the inner insulating layer enclosing the electrode clip, the noise-proof layer enclosing the inner insulating layer, and the exposed section of the metal shield.

[0035] The above disclosure is merely a preferred embodiment of the present invention, and does not limit the scope of the claims of the present invention. Therefore, all equivalent technical modifications made based on the contents of the specification and accompanying drawings of the present invention shall be included in the scope of the claims of the present invention.
