Description

Technical Field

In applications, most conventional medical device connectors use conductive terminal transfers, and there is a certain amount of energy loss in signal transmission, so relatively more pins are needed.

On the other hand, the larger cross-sectional size of the connector also results in a larger size of the metal shielding ring inside the connector, which results in higher production and assembly costs.

The second shielding ring 100 can be matched and sleeved between the first shielding ring 50 and the first shell 10, and the second shielding ring 100 is provided with an elastic snap-fit ​​piece 110 that can adapt to the first shell 10; pushing the second shell 60 to be matched and sleeved on the periphery of the first shell 10 can drive the second shielding ring 100 to be matched and sleeved on the periphery of the first shielding ring 50, and simultaneously press each conductive spring sheet 70 against a conductive contact 21, and the elastic snap-fit ​​piece 110 can be matched and fixed on the first shell 10 to tighten the male end 200 and the female end 300.

[0034] The utility model uses a structure in which a plurality of conductive contacts 21 and conductive springs 70 are matched and connected one by one to replace the conventional male and female terminals, and integrates a plurality of conductive contacts 21 on a plurality of PCBs 20, so as to achieve the purpose of reducing the volume of the connector. The structure is compact and can ensure the stability of signal transmission, and densely arranged electrical signal conduction elements can be arranged in a narrow space; by respectively arranging a first shielding ring 50 and a second shielding ring 100 on the periphery of the PCB 20 and the periphery of the conductive spring 70, and allowing the two shielding rings to be sleeved on the inner side of the first shell 10 when plugged in, the space can be effectively utilized and the shielding protection of the internal electrical signal conduction elements can be enhanced, so as to avoid or reduce the signal transmission distortion caused by external electromagnetic interference and ensure the sensitivity of signal transmission; by arranging an elastic snap-fit ​​component 110, the structural stability of the connector after plugging can be ensured, so that the operator can operate it with one hand and it is convenient to use.

[0035] like Figure 4-5As shown, in a further design, the outer wall and the inner wall of the first shell 10 on the male end 200 and the outer wall of the first shielding ring 50 are all stepped structures: a first card slot 11 adapted to the elastic snap member 110 is provided on the side wall of the larger end of the first shell 10; the larger end of the first shielding ring 50 is matched and embedded on the inner wall of the first shell 10 with a smaller inner diameter and extends to the outside of the first shell 10, and the first shielding ring 51 is inside the first shell 10; a first rubber core 120 is matched and embedded on the inner wall of the first shielding ring 50, and a plurality of PCBs 20 are matched and embedded on the first rubber core 120, each PCB 20 extends axially and its two ends extend to the outside of the first rubber core 120; one end of the first sheath 40 is matched and sleeved on the first shell 10 is around the larger end, and a first inner ring 130 is also sleeved on its inner side. One end of the first inner ring 130 is sleeved on the outer periphery of the first shielding ring 50 and abuts on the shoulder of the first shell 10. One end of the first sleeve 40 extends to the outside of the first inner ring 130. The first connecting member 30 includes a first guide ring 31 and a second guide ring 32. The first guide ring 31 is matched and embedded in the end of the first inner ring 130 away from the female end 300, and the second guide ring 32 is matched and embedded in the end of the first sleeve 40 away from the female end 300. The outer wall of the first shielding ring 50 is also embedded with a circumferentially extending retaining spring 140 and an axially extending first slide groove 51. The first slide groove 51 is adapted to the elastic snap member 110 and is arranged directly below the first slot 11.

[0036] It is understandable that if Figure 2 , 4 As shown, the structural arrangement of the first shell 10 and the first shielding ring 50 can not only form a space between the two to avoid the second shielding ring 100, but also facilitate the connection and fixation of the first shell 10, the first shielding ring 50, the first inner ring 130 and the first sheath 40 together, which is convenient for production and assembly; the retaining spring 140 can abut against the inner wall of the second shielding ring 100 during insertion, so that the two shielding rings are abutted and connected together, and the axes of the two are adjusted to coincide for insertion. In the above embodiment, as Figure 2 As shown, a guide protrusion 52 is formed on the inner wall of the first shielding ring 50, which is adapted to the first rubber core 120 and extends axially, so as to ensure the relative position accuracy of the first rubber core 120 and the PCBs 20 inside it (ie, the conductive contacts 21) and the first shell 10.

[0037] like Figure 4As shown, in some embodiments of the utility model, for the convenience of production and assembly, the first inner ring 130 is formed by buckling two matching semi-circular shells, and a positioning structure adapted to the first shielding ring 50 and the first guide ring 31 is provided on the inner wall thereof; the first guide ring 31 and the second guide ring 32 are both wire rings, and a cable passes through the second guide ring 32 and the first guide ring 31 in sequence and is electrically connected to the PCB 20. In another embodiment of the utility model, the first guide ring 31 is a wire ring, and the second guide ring 31 is a terminal block with a conductive copper ring at one end, and one end of a cable is connected to the terminal block, and the other end passes through the first guide ring 31 and is electrically connected to the PCB 20. In application, according to actual conditions, the second guide ring 32 can be set as a terminal block of other types and structures to meet the connection needs of different connecting devices on different devices. The terminal block is an electrical connecting device that can be connected to a cable at one end and can be connected to a conductive structural member at the other end. It is common knowledge of those skilled in the art, and its structure is not described here.

[0038] like Figure 6-7 As shown, in a further design, the inner wall of the second shell 60 on the female end 300 and the inner wall and outer wall of the second shielding ring 100 are all step structures: the larger end of the second shielding ring 100 is matched and embedded on the inner wall of the second shell 60 with a smaller inner diameter and extends to the outside of the second shell 60 and is provided with an elastic snap-fit ​​member 110, one end of the elastic snap-fit ​​member 110 extends axially toward the male end 200, and a second rubber core 150 is matched and embedded on the inner wall of the second shielding ring 100, and a plurality of first limiting protrusions 151 adapted to the inner wall of the first shielding ring 50 are provided on the outer wall of the second rubber core 150, and the end of the second rubber core 150 away from the male end 200 extends to the outside of the second shielding ring 100, and a plurality of tongue plates 160 arranged in parallel and extending along the axial direction are provided in the second rubber core 150, and each tongue plate 160 is provided with a row of conductive spring sheets 70, and each conductive spring sheet 70 includes an axially arranged The second shielding ring 100 and the second rubber core 150 are matched and embedded in the inner wall of a second inner ring 170, and the other end of the second inner ring 170 extends to the outside of the conductive spring 70 and the second connecting piece 80 is matched and embedded in the inner wall thereof. A plurality of second protrusions 171 are axially arranged on the outer wall of the second inner ring 170, and a plurality of second grooves 91 matching the second protrusions 171 are arranged on the inner wall of the second sheath 90. The second sheath 90 is matched and sleeved on the outer periphery of the second inner ring 170, and one end thereof abuts against the end of the second shell 60 away from the male end 200, and the other end extends to the outer side of the second inner ring 170 and extends to the outer periphery of the second connecting piece 80.

[0039] It is understandable that if Figure 3 , 6As shown, the structural setting of the second shell 60 and the second shielding ring 100 can not only form a space between the two to avoid the first shell 10, but also facilitate the connection and fixation of the second shell 60, the second shielding ring 100, the second inner ring 170 and the second sheath 90 together, which is convenient for production and assembly; the first limiting protrusion 151 on the second rubber core 150 can limit the relative distance between the male end 200 and the female end 300 when plugged in by limiting the position of the first shielding ring 50, ensuring that the conductive spring sheet 70 is in one-to-one contact and connection with the conductive contact 21, and can work together with the retaining spring 140 to improve the plugging and unplugging feel.

[0040] like Figure 4 , 6 As shown, in some embodiments of the utility model, the second inner ring 170 is formed by two matching upper and lower semi-circular shells that are buckled together, and a positioning structure that is adapted to the second shielding ring 100 and the second connecting member 80 is provided on the inner wall; a waterproof sealing member 180 is provided between the first shell 10 and the first sheath 40 and / or between the first sheath 40 and the first connecting member 30 and / or between the second shell 60 and the second sheath 80 and / or between the second sheath 80 and the second connecting member 80, and a third shielding member 190 is provided on the first connecting member 30 and / or the second connecting member 80.

[0041] It can be understood that the waterproof seal 180 can prevent or slow down the entry of external water vapor or foreign matter into the male end 200 or the female end 300 through the connection gaps of the structural components, and the third shielding component 190 can further prevent or slow down the influence of external electromagnetic interference on the cable (and its inner core) or the terminal at the first / second connector, thereby ensuring the fidelity and stability of signal transmission.

[0042] In some embodiments of the present invention, the second connector 80 is a wire loop, and a cable passes through the second connector 80 and is electrically connected to the connecting portion 71 of the conductive spring 70. In another embodiment of the present invention, the second connector 80 is a wiring terminal with a conductive copper ring at one end, and one end of a cable is connected to the wiring terminal, and the other end is electrically connected to the connecting portion 71. In applications, the second connector 80 can be set as a wiring terminal of other types and structures according to actual conditions to meet the connection needs of different connecting devices on different devices.

The support plate 111 is arranged at one end of the second shielding ring 100 and extends axially to the outside thereof. The support plate 111 is provided with an axially extending second slide groove 114, and the slide plate 112 is slidably mounted on the second slide groove 114. A button 115 is formed in the portion 112 of the slide plate, and a spring 113 is arranged at the lower end of the button 115. A third clamping protrusion 116 adapted to the first clamping groove 11 is formed at the end of the slide plate 112 facing the male end 200, and the two ends of the spring 113 are respectively against the slide plate 112 and the support plate 111; as shown in FIG. Figure 6 As shown, an avoidance protrusion 172 for avoiding the support plate 111 and the slide plate 112 is formed on the outer wall of the second inner ring 170, the bottom end of the avoidance protrusion 172 is at the outer waterproof seal 180 of the button 115, the avoidance protrusion 172 is provided with a guide hole groove 173 adapted to the button 115, and the second sheath 90 is provided with an avoidance hole groove 92 adapted to the avoidance protrusion 172.

[0044] When in use, hold the female end 300 with one hand and insert it into the male end 200, and press the button 115 with one finger, so that the slide plate 112 drives the third latching protrusion 116 to move radially downward toward the second shielding ring 100. After being inserted into place, release the button 115, and the spring 113 resets and pushes the third latching protrusion 116 to move upward and snap into the first slot 11, so that the female end 300 is clamped and fixed on the male end 200, which is convenient to operate.

[0045] like Fig. 9 As shown, in some embodiments of the present invention, a row of conductive contacts 21 are provided on the upper and lower end surfaces of each PCB20; the number of conductive contacts 21 on the upper and lower end surfaces of each PCB20 is the same, and the position projections overlap each other; each tongue plate 160 is integrally formed with a plurality of conductive spring sheets 70 thereon, and two adjacent tongue plates 160 are matched and buckled together, and the bending portions 72 of the two rows of conductive spring sheets 70 thereon are bent toward each other, and the spacing d between the two adjacent rows of bending portions 72 is equal and less than the thickness t of the PCB20.

[0046] It can be understood that the bent conductive spring sheet 70 and the small bending portion spacing d can be pressed against the conductive contact 21 by their own deformation during insertion and are not easy to loosen, ensuring the continuous stability of the electrical connection. In this embodiment, three PCBs 20 are arranged in parallel on the male end 200, and a row of conductive contacts 21 are arranged at the upper and lower ends of each PCB 20. A total of 66 conductive contacts 21 are arranged on the three rows of PCBs 20. Six tongue plates 160 are arranged in parallel on the female end 300, and each tongue plate 160 is integrally formed with a row of conductive spring sheets through an in-mold molding process. A total of 66 conductive spring sheets 70 are arranged on the six tongue plates 160. Two adjacent tongue plates 160 are buckled together to form three groups of spring sheet groups, and each group of spring sheet groups is adapted to a PCB 20 and crimped on the conductive contacts 21 on its upper and lower end surfaces.

[0047] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
