Description

Technical Field

[0002] Medical devices often require high precision, so the connectors they use must offer stable and reliable signal transmission performance. Conventional medical device connectors often use conductive terminal adapters, which incur energy losses during signal transmission. Consequently, a relatively large number of pins are required. However, due to electromagnetic interference, pins cannot be placed too close together. This results in medical connectors being large and heavy, making them difficult to operate with one hand. This can easily lead to pins not being properly inserted or connections being unstable. Furthermore, the larger cross-sectional dimensions of the connector also result in larger metal shielding rings within the connector, resulting in higher production and assembly costs.

[0031] like Figure 1 As shown, a high-density mating connector for medical devices includes a male end 200 and a female end 300 that can be mated and plugged.

[0032] like Figure 2As shown, the male end 200 includes a ring-shaped first shell 10 and several PCBs 20 embedded therein and arranged in parallel. One end of each PCB 20 is arranged with several conductive contacts 21. One end of the several PCBs 20 extends to the outside of the first shell 10 and is electrically connected to the first connector 30, and the outer periphery of the connection is provided with a first sheath 40. The first sheath 40 extends to the side of the first shell 10 and is connected to it. A first shielding ring 50 is provided on the periphery of the several conductive contacts 21 in the first shell 10.

[0033] like Figure 3 As shown, the female end 300 includes a ring-shaped second shell 60 and a plurality of conductive springs 70 embedded therein. When plugged in, one end of the plurality of conductive springs 70 is connected to the plurality of conductive contacts 21 one by one, and the other end of the plurality of conductive springs 70 extends to the outside of the second shell 60 and is electrically connected to the second connector 80. A second sheath 90 is provided around the outer periphery of the connection, and the second sheath 90 extends to the side of the second shell 60 and is connected thereto. A second shielding ring 100 is provided around the outer periphery of the plurality of conductive springs 70 in the second shell 60. The second shielding ring 100 can be matched and sleeved between the first shielding ring 50 and the first shell 10. The second shielding ring 100 is provided with an elastic snap-fit ​​component 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. The elastic snap-fit ​​component 110 can be matched and fixed on the first shell 10 to tighten the male end 200 and the female end 300.

[0034] The present invention uses a structure in which several conductive contacts 21 and conductive springs 70 are matched one by one to replace the conventional male and female terminals, and integrates several conductive contacts 21 on multiple PCBs 20 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 small 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, thereby avoiding or reducing signal transmission distortion caused by external electromagnetic interference and ensuring the sensitivity of signal transmission; by arranging an elastic snap member 110, the structural stability of the connector after plugging can be ensured, which is convenient for the operator to operate with one hand and is easy to use.

[0035] like Figure 4-5As shown, a further design is shown, 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 groove 11 adapted to the elastic snap fastener 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, a first inner ring 130 is sleeved on the inner side of the larger end thereof, one end of the first inner ring 130 is sleeved on the outer periphery of the first shielding ring 50 and rests on the shoulder of the first shell 10, and 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; a circumferentially extending retaining spring 140 and an axially extending first slide groove 51 are also embedded on the outer wall of the first shielding ring 50, 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 when plugging in, so as to abut and connect the two shielding rings together, and adjust the axis of the two to coincide for plugging in. 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, thereby ensuring the relative position accuracy of the first rubber core 120 and the PCBs 20 inside it (i.e., the conductive contacts 21) and the first shell 10.

[0037] like Figure 4As shown, in some embodiments of the present invention, to facilitate production and assembly, the first inner ring 130 is formed by snapping together two matching semi-circular shells, with its inner wall provided with a positioning structure adapted for the first shielding ring 50 and the first guide ring 31. The first guide ring 31 and the second guide ring 32 are both wire loops, through which a cable passes, in sequence, through the second guide ring 32 and the first guide ring 31 and is electrically connected to the PCB 20. In another embodiment of the present invention, the first guide ring 31 is a wire loop, and the second guide ring 31 is a terminal block with a conductive copper ring at one end. A cable is connected to the terminal block at one end and passes through the first guide ring 31 at the other end and is electrically connected to the PCB 20. In actual applications, the second guide ring 32 can be configured as a terminal block of other types and structures to meet the connection needs of different connectors on different devices. A terminal block is an electrical connector that can connect to a cable at one end and to a conductive structural member at the other end. This is common knowledge among those skilled in the art, and its structure is not described in detail here.

[0038] like Figure 6-7 As shown, a further design is shown, 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 stepped 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 in the axial direction are provided in the second rubber core 150, and each tongue plate 160 is provided with a row of conductive spring clips 70, and each conductive spring clip 70 includes an axially arranged The connecting portion 71 and the bending portion 72 are arranged, each connecting portion 71 extends to the outside of the second rubber core 150, and each bending portion 72 extends to the outside of the tongue plate 160 and is located on the inside of the second shielding ring 100; the ends of the second shielding ring 100 and the second rubber core 150 are matched and embedded on 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 on its inner wall. A plurality of second clamping protrusions 171 are axially provided on the outer wall of the second inner ring 170, and a plurality of second clamping grooves 91 that are matched one by one with the second clamping protrusions 171 are provided 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 outside 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 arrangement 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 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 present invention, the second inner ring 170 is formed by two matching upper and lower semi-circular shells that are fastened 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, through which a cable passes 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 terminal block with a conductive copper ring at one end, and a cable is connected to the terminal block at one end and electrically connected to the connecting portion 71 at the other end. Depending on the actual application, the second connector 80 can be configured as a terminal block of other types and structures to meet the connection needs of different connectors on different devices.

[0043] like Figure 8As shown, in some embodiments of the present invention, the elastic snap fastener 110 includes a support plate 111, a slide plate 112 and a spring 113. The support plate 111 is provided at one end of the second shielding ring 100 and extends axially to its outside. 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 on the middle portion 112 of the slide plate, and a spring 113 is provided at the lower end of the button 115. A third latching protrusion 116 adapted to the first slot 11 is formed at the end of the slide plate 112 facing the male end 200, and the two ends of the spring 113 respectively abut against the slide plate 112 and the support plate 111; as shown 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, and 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 to make the slide 112 drive the third locking protrusion 116 to move radially downward toward the second shielding ring 100. After it is inserted into place, release the button 115, and the spring 113 resets to push the third locking protrusion 116 to move upward and snap into the first slot 11, clamping the female end 300 on the male end 200, which is convenient to operate.

[0045] like Figure 9 As shown, in some embodiments of the present invention, a row of conductive contacts 21 is provided on the upper and lower end surfaces of each PCB 20; the number of conductive contacts 21 on the upper and lower end surfaces of each PCB 20 is the same, and the position projections overlap each other; each tongue plate 160 is integrally formed with the plurality of conductive springs 70 thereon, and two adjacent tongue plates 160 are matched and buckled together, and the bending portions 72 of the two rows of conductive springs 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 PCB 20.

[0046] It is understood that the bent conductive springs 70 and the relatively small bend spacing d allow them to be compressed against the conductive contacts 21 through their own deformation during insertion and prevent them from loosening, ensuring a continuous and stable electrical connection. In this embodiment, three PCBs 20 are arranged in parallel on the male end 200, each PCB 20 having a row of conductive contacts 21 at its upper and lower ends, for a total of 66 conductive contacts 21 arranged on the three rows of PCBs 20. Six tongues 160 are arranged in parallel on the female end 300, each tongue 160 being integrally formed with a row of conductive springs through an in-mold molding process. A total of 66 conductive springs 70 are arranged on the six tongues 160, and two adjacent tongues 160 are buckled together to form three groups of springs. Each group of springs is adapted to a PCB 20 and crimped onto the conductive contacts 21 on its upper and lower ends.

[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.
