Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to an endoscope connector and an endoscope. Background Technology

[0002] As technology continues to evolve, medical devices are becoming increasingly sophisticated and complex. Some devices can be equipped with different types of components, allowing them to perform various tasks by disassembling and assembling different parts. Others allow for the separate sterilization of parts that enter the body, simplifying the sterilization process, improving sterilization effectiveness, and preventing disinfectants from affecting less waterproof parts of the device.

[0003] To ensure reliable electrical connection between the endoscope and its peripheral devices (e.g., endoscope light source, endoscope processor, etc.), spring pins (e.g., Pogo pins) can be used to make electrical contact with fixed electrical contacts. The spring pins can be positioned on the side that does not require sterilization (e.g., the endoscope light source or endoscope processor), while the electrical contacts, each adapted to a spring pin, are positioned on the detachable part that needs sterilization (e.g., the endoscope connector). During sterilization, only the end face of the electrical contact contact comes into contact with the disinfectant, thus minimizing the contact area with the disinfectant and preventing damage to the spring inside the spring pin.

[0004] Commercially available endoscope connectors solve the waterproofing problem by applying adhesive or installing sealing rings around each electrical contact pin, allowing for convenient sterilization with disinfectants without concerns about water ingress. However, current assembly methods, such as individually pressing the electrical contact pins into the housing, may result in lower assembly precision and poor uniformity. Therefore, there is a need for an endoscope connector that simultaneously meets requirements for high temperature resistance, chemical resistance, high precision, and a high waterproof rating. Utility Model Content

[0005] To at least partially address the problems existing in the prior art, one aspect of this application provides an endoscope connector, comprising: an insulating housing and a plurality of electrical contact pins; the insulating housing includes an insulating base having a mating surface and a mounting surface, the mating surface and the mounting surface being opposite to each other along a mating direction, and the mounting surface having an inwardly recessed groove; the plurality of electrical contact pins are fixed to the insulating base and located within the groove, each of the plurality of electrical contact pins including a contact end and a connecting end located at both ends, the contact end extending to and exposed on the mating surface, and the connecting end extending beyond the mounting surface; wherein the insulating base is injection molded onto the plurality of electrical contact pins, and the groove is filled with sealant, the thickness of which does not exceed the depth of the groove.

[0006] As an example, the endoscope connector may also include a board disposed within an insulating base and electrically connected to a plurality of electrical contact pins.

[0007] For example, each of the plurality of electrical contact pins includes a first segment and a second segment, the first segment and the second segment being arranged along a mating direction, a connecting end being formed in the first segment, the first segment being thinner than the second segment, the first segment being inserted into the board and electrically connected to the board.

[0008] For example, the connection between the first segment and the second segment forms a stepped surface perpendicular to the mating direction, and the plate abuts against the stepped surface.

[0009] For example, the stepped surface is further away from the mating surface than the mounting surface.

[0010] For example, the insulating base includes a flange disposed on the periphery of the mounting surface and protruding from the mounting surface, the flange enclosing to form a mounting groove for receiving a board.

[0011] For example, the number of glue trays is less than the number of multiple electrical contact pins, and at least a portion of the multiple electrical contact pins are located in the same glue tray.

[0012] For example, the insulating base is disc-shaped, and a plurality of electrical contact pins are arranged around the axis of the insulating base.

[0013] For example, the end face of the contact end is a flat contact surface perpendicular to the mating direction, and the contact surface is flush with or protrudes from the mating surface.

[0014] Another aspect of this application provides an endoscope, which includes the endoscope connector described above.

[0015] In the above technical solution, by fixing the electrical contact pins inside the mold and injection molding an insulating base around them, a tight fit between the electrical contact pins and the insulating base is achieved. Furthermore, because the electrical contact pins are firmly fixed by the mold during injection molding, the installation accuracy of all electrical contact pins on the endoscope connector is high, and the consistency is excellent. Based on in-mold injection molding, by setting a glue groove and filling it with sealant, even if gaps occur during use due to the difference in the expansion coefficients of the electrical contact pins and the insulating base, liquid cannot penetrate the interior of the insulating base through the protective sealant, ensuring the waterproof, high-temperature resistance, and chemical resistance of the insulating base. Placing the sealant on the mounting surface opposite to the mating surface prevents sealant from overflowing into the contact surface of the electrical contact pin used for contacting the spring pin, thus avoiding impact on conductivity. Additionally, during sterilization, the amount of disinfectant penetrating the sealant is very small, having almost no impact on its performance, thereby improving the service life of the endoscope connector.

This utility model description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

Detailed Implementation

[0026] In the following description, numerous details are provided to enable a thorough understanding of this application. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the application by way of example only. Furthermore, to avoid confusion with this application, some technical features well-known in the art have not been described in detail.

[0027] This application provides an endoscope connector. The endoscope connector can be connected to an endoscope host unit. In some embodiments, the endoscope light source and endoscope processor can be integrated into the endoscope host unit, so the endoscope connects to the endoscope host unit via the endoscope connector to receive illumination light for image acquisition by the endoscope. In this case, the endoscope connector is also used to transmit control signals and image signals between the endoscope host unit and the endoscope. In still other embodiments, the endoscope light source can be independent of the endoscope processor. The endoscope connector can transmit illumination light, control signals, and image signals between the endoscope and the endoscope light source, and then transmit control signals and image signals between the endoscope light source and the endoscope processor. In yet another embodiment, the endoscope light source can be disposed within the endoscope. In this case, the endoscope connector is used to transmit control signals and image signals between the endoscope and the endoscope processor.

[0028] Figure 1 An endoscope connector is shown. Figures 2 to 5 An insulating base 100 for an endoscope connector, on which electrical contact pins 200 are mounted, is shown. (See diagram.) Figure 1 As shown, the endoscope connector 10 may include an insulating housing. The insulating housing is used to house and mount various components inside the endoscope connector 10, such as tubing, cables, etc. The insulating housing may have an insulating base 100 for mating to an adapted endoscope device (e.g., endoscope light source, endoscope processor, or endoscope main unit). See also [reference needed]. Figures 2 to 5The insulating base 100 has a mating surface 110 and a mounting surface 120. The mating surface 110 and the mounting surface 120 are opposite to each other along the mating direction. The mating direction is the axial direction of the insulating base 100. The mounting surface 120 is provided with an inwardly recessed groove 121. The insulating base 100 can be molded from a material such as plastic. The plastic can include, but is not limited to, liquid crystal polymer (LCP), polyphenylene sulfide (PPS), high-temperature nylon, or poly(p-phenylene oxide) (PPO) or polypropylene (PP), or any other suitable material. In some cases, the plastic can be a thermosetting plastic. In some cases, the insulating plastic can contain insulating materials such as glass fiber reinforced materials. The insulating base 100 shown in the figure is constructed in a disk shape, thereby having a smaller thickness and a larger contact area in the mating direction. In embodiments not shown, the insulating base 100 can also be constructed in a square, prismatic, or other irregular shape, and its length in the mating direction may be longer or shorter, as long as it can be adapted to the part to be connected.

[0029] The endoscope connector 10 may also include a plurality of electrical contact pins 200. The electrical contact pins 200 may be made of solid metal, specifically copper and copper alloys, iron and iron alloys, etc., and their surfaces may be plated with a noble metal layer to improve their corrosion resistance. Alternatively, the electrical contact pins 200 may also be constructed as hollow metal tubes or made of non-metallic conductive materials. Each of the plurality of electrical contact pins 200 includes a contact end 201 and a connecting end 202 located at both ends. The contact end 201 extends to and is exposed on the mating surface 110. The connecting end 202 extends beyond the mounting surface 120. Specifically, along the mating direction, the connecting end 202 is further away from the mating surface 110 relative to the mounting surface 120. The electrical contact pin 200 can be straight, with the contact end 201 and the connecting end 202 located on opposite sides along the mating direction; the electrical contact pin can also be curved, for example, bent in the middle so that the contact end 201 faces the mating direction, and the connecting end 202 faces an angle with the mating direction. The shape of the electrical contact pin 200 can also be selected according to the application requirements; for example, the cross-section of the electrical contact pin 200 can be circular or prismatic. For ease of understanding, the following will use... Figure 1 and Figure 2 The straight electrical contact needle 200 with a circular cross-section shown is used as an example for detailed explanation. Figure 2 In the illustrated embodiment, the contact end 201 may have a flat end face, namely the contact surface 211 mentioned below. The end of a spring pin (e.g., a Pogo pin) may abut against the contact surface 211 to form an electrical contact. In embodiments not shown, the contact surface 211 may also be configured to have a shape adapted to the end of a spring pin (e.g., a Pogo pin).

[0030] A portion of one of the multiple electrical contact pins 200 near the connecting end 202 can pass through the adhesive groove 121, for example, through the bottom surface of the adhesive groove 121. The connecting end 202 can extend beyond the adhesive groove 121. The adhesive groove 121 is filled with sealant 300 (e.g., ...). Figure 4 As shown, the thickness of the sealant 300 does not exceed the depth of the adhesive groove 121. The sealant 300 can cover the gap between the electrical contact pin 200 and the adhesive groove 121 to prevent liquid from entering the interior of the insulating base 100. The connecting end 202 can protrude beyond the sealant 300 along the mating direction to electrically connect with a component disposed within the insulating housing. The sealant 300 can be a waterproof adhesive such as epoxy resin, UV photosensitive adhesive, or silicone rubber, and the curing method can be any suitable method such as mixed curing, heat curing, UV curing, or moisture curing. Exemplarily, the adhesive groove 121 can be located in the edge region of the mounting surface 120 so that the plurality of electrical contact pins 200 are aligned and connected to the pads and vias on the edge region of the board 400, which will be described later.

[0031] The insulating base 100 can be injection molded onto a plurality of electrical contact pins 200. In manufacturing the insulating base 100 of the endoscope connector 10, the electrical contact pins 200 are first fixed. The mold can cover the connecting end 202 of the electrical contact pin 200 and the corresponding position in the glue groove 121. The end face of the contact end 201 can abut against the ejector pin of the mold on the other side. During the injection molding process, the insulating base 100 is formed around the portion of the electrical contact pin 200 located within the mold and not covered by the mold. This process can also be referred to as in-mold injection molding. In some embodiments, the side surface of the electrical contact pin 200 has a raised and / or recessed structure, and the injection-molded insulating base 100 forms a complementary structure with these raised and / or recessed structures, limiting the electrical contact pin 200 in the axial direction or around the axis of the electrical contact pin 200.

[0032] In the above technical solution, by fixing the electrical contact pin 200 inside the mold and injection molding an insulating base 100 around the electrical contact pin 200, the electrical contact pin 200 and the insulating base 100 can be tightly joined. Furthermore, because the electrical contact pin 200 is firmly fixed by the mold during injection molding, all electrical contact pins 200 on the endoscope connector 10 have high precision and good consistency. Based on in-mold injection molding, by setting a glue groove 121 and filling it with sealant 300, even if gaps occur due to the different expansion coefficients of the electrical contact pin 200 and the insulating base 100, liquid cannot enter the interior of the component through the protection formed by the sealant 300, ensuring the component's waterproof performance, heat resistance, and chemical resistance. Applying sealant 300 to the mounting surface 120 serves two purposes: firstly, it prevents sealant from overflowing into the contact surface 211 of the electrical contact pin 200, which is used to connect with the spring pin, thus affecting conductivity; secondly, during disinfection, almost no disinfectant comes into contact with sealant 300 and causes a chemical reaction, so the performance of sealant 300 is not affected, thereby improving the service life of endoscope connector 10.

[0033] like Figure 5 As shown, the endoscope connector 10 may also include a board 400. The board 400 may include, but is not limited to, circuit boards such as FPGAs. The board 400 can be used to perform power control, signal control, image processing, and / or light source control. The board 400 can be disposed within the insulating base 100 and electrically connected to multiple electrical contact pins 200. The connection ends 202 of the multiple electrical contact pins 200 can be inserted one-to-one into the pad vias of the board 400. The electrical connection between the board 400 and the electrical contact pins 200 can be achieved by inserting the connection ends 202 through the pad vias and then soldering them. Therefore, the internal structure of the endoscope connector 10 can be more compact and can achieve higher precision.

[0034] refer to Figure 4 and Figure 5For example, each of the plurality of electrical contact pins 200 includes a first segment 210 and a second segment 220. The first segment 210 is thinner than the second segment 220. The first segment 210 and the second segment 220 are arranged along a mating direction. A connecting end 202 may be formed in the first segment 210, which can be inserted into and electrically connected to the board 400 to be connected. Taking a solid electrical contact pin 200 as an example, the larger the diameter of the electrical contact pin 200, the faster the heat is conducted during soldering. On the one hand, this may lead to insufficient temperature at the solder joint during soldering, resulting in incomplete melting of the solder and a poor solder joint. On the other hand, a large amount of heat is conducted to the sealant 300 and the insulating base 100 during soldering, causing gaps in the contact portions between the two and the electrical contact pin 200, and even causing damage to the endoscope connector 10. The thinner first segment 210 of the electrical contact pin 200 can heat up quickly during soldering, making soldering easier, while not conducting a large amount of heat to the second segment 220. Since the current required to be transmitted by the endoscope connector 10 is usually small, the thinner first segment 210 will not affect its electrical performance.

[0035] like Figure 4 and Figure 5 As shown, exemplarily, a stepped surface 230 perpendicular to the mating direction can be formed at the connection between the first segment 210 and the second segment 220. After the first segment 210 is inserted into the plate 400, the plate 400 can abut against the stepped surface 230. In this way, the plate 400 can be limited by the stepped surface 230, which facilitates the installation operation. Furthermore, the stepped surface 230 can also make the installation of the plate 400 more secure.

[0036] To prevent sealant 300 from overflowing onto the stepped surface 230, which could lead to poor contact between the electrical contact pin 200 and the circuit board 400, or prevent the circuit board 400 from being installed flat due to the sealant 300, the stepped surface 230 can be located outside the sealant 300. Optionally, the stepped surface 230 can serve as an indicator surface for the sealant 300. During dispensing, dispensing can be stopped when the liquid sealant 300 level is a preset distance from the stepped surface 230. For example, the preset distance can be 0.3mm, 0.5mm, or 1mm, and can be specifically set according to the height of the stepped surface 230 from the bottom of the glue groove 121 and the sealing requirements, as long as the sealant 300 does not submerge the stepped surface 230. Optionally, the stepped surface 230 can also be set higher than the glue groove 121, with the groove opening of the glue groove 121 serving as the indicator surface, completely filling the glue groove 121 with sealant 300. During the dispensing process, if some sealant 300 flows out of the glue tank 121, the excess sealant 300 can be wiped off with alcohol before curing, thus reducing the process difficulty. For example, one end of the second segment 220 connected to the first segment 210 can be partially accommodated within the glue tank 121, with a small portion protruding outside the glue tank 121, allowing the stepped surface 230 to be located outside the sealant 300. A contact end 201 can be formed in the second segment 220. A portion of the second segment 220 near the contact end 201 can be embedded within the insulating base 100.

[0037] like Figure 4 and Figure 5 As shown, exemplarily, the stepped surface 230 can be further away from the mating surface 110 relative to the mounting surface 120. This provides better support for the plate-shaped plate 400, avoids interference between the plate 400 and the mating surface 110, and also ensures sufficient clearance between the stepped surface 230 and the sealant 300.

[0038] like Figure 3 and Figure 5 As shown, exemplarily, the insulating base 100 may include a flange 122 disposed around and protruding from the mounting surface 120, the flange 122 forming a mounting groove for receiving the board 400. Figure 3 and Figure 5 In the illustrated embodiment, flange 122 may be closed, with board 400 surrounded within a mounting groove formed by flange 122, while flange 122 may provide additional waterproof protection around board 400. Flange 122 may also be used to position board 400 during installation. Optionally, as... Figure 3As shown, the inner edge of the flange 122 may also be provided with a chamfer 124. The chamfer 124 can be a smooth bend. During the process of installing the board 400 into the insulating base 100, the chamfer 124 can prevent the edge of the board 400 from scratching the flange 122, thus avoiding damage to the board 400 and / or the insulating base 100 caused by scratching. In the illustrated embodiment, the flange 122 can completely surround the mounting groove, that is, completely surround the board 400 installed therein. In some embodiments not shown, the flange 122 may not completely surround the mounting groove. For example, a notch may be provided in the flange 122, so that the mounting groove has a partially open side. This facilitates the adjustment of the position of the board 400 in the mounting groove, facilitates the installation of the board 400 into the insulating base 100, and saves materials and reduces production costs.

[0039] like Figure 3 As shown, exemplarily, the number of glue channels 121 is less than the number of multiple electrical contact pins 200, and at least a portion of the multiple electrical contact pins 200 are located in the same glue channel 121. When there are a large number of electrical contact pins 200, providing an independent glue channel around each electrical contact pin 200 would complicate the mold structure and increase mold costs. Conversely, connected glue channels 121 can simplify the mold structure. Compared to dispensing glue around each electrical contact pin 200, connected glue channels 121 allow the sealant 300 to flow. In other words, when using a sealant 300 with good flowability, dispensing only needs to be performed at one or a few points within the glue channel 121, and the sealant 300 can flow level within the glue channel 121, thus sealing the joint between all electrical contact pins 200 and the insulating base 100. Figure 3 In the embodiment shown, there is one glue groove 121, and the connection ends 202 of all electrical contact pins 200 extend beyond the mounting surface 120 through the glue groove 121.

[0040] In some embodiments, the electrical contact pins 200 of the endoscope connector are arranged relatively dispersedly. If a single adhesive groove 121 is used, allowing the groove to pass through every electrical contact pin 200, the consumption of sealant 300 may increase significantly. Therefore, by way of example, there can be multiple adhesive grooves 121, and the multiple electrical contact pins 200 can be divided into multiple groups, with each group of electrical contact pins 200 disposed in a different adhesive groove 121. Among the multiple groups of electrical contact pins 200, at least one group includes two or more electrical contact pins 200.

[0041] In summary, when the electrical contact pins 200 are densely arranged, ensuring that all pins 200 pass through the same glue groove 121 simplifies mold design and the dispensing process, thereby reducing production costs. Conversely, when one or more electrical contact pins 200 are spaced far apart from each other, multiple glue grooves 121 can be constructed, and these grooves 121 are not connected to each other. This eliminates the need to wait for the sealant 300 to flow through a long glue groove 121, reducing sealant consumption; furthermore, the mold does not require additional design to connect the disparate glue grooves 121.

[0042] like Figure 3 As shown, exemplarily, the insulating base 100 is disc-shaped, with a plurality of electrical contact pins 200 arranged around the axis of the disc. This results in a relatively large mating surface 110, allowing for the arrangement of a plurality of electrical contact pins 200 on the mating surface 110. The arrangement of the plurality of electrical contact pins 200 around the axis of the disc allows the width of the adhesive groove 121 to be close to the diameter of the electrical contact pins 200, while extending through all of the electrical contact pins 200, provided the electrical contact pins 200 are appropriately spaced. This results in a smaller volume of adhesive groove 121, requiring less sealant 300. The smaller thickness of the insulating base 100 also allows the electrical contact pins 200 to penetrate from the mounting surface 120 to the mating surface 110 without requiring a large length. Endoscope connectors employing this shape and arrangement of electrical contact pins 200 can be used to mate with the spring pin arrangement and shape of the endoscope connector 10.

[0043] like Figure 3 As shown, exemplarily, the insulating base 100 includes a boss 123 protruding along the mating direction, a flange 122 surrounding the boss 123, and at least a portion of the flange 122 being spaced apart from the boss 123 to form a groove 121. In other words, one sidewall of the groove 121 may be formed by the inner surface of the flange 122, and the other sidewall may be formed by the outer surface of the boss 123. The boss 123 is injection molded, and retaining the boss 123 within the insulating base 100 can improve the structural strength of the insulating base 100. Retaining the boss 123 also allows the width of the groove 121 to adapt to the electrical contact pin 200, thereby reducing the consumption of sealant 300.

[0044] like Figure 2 As shown, exemplarily, the end face of the contact end 201 is a flat contact surface 211 perpendicular to the mating direction. The contact surface 211 is flush with or protrudes from the mating surface 110. This prevents the formation of holes in the mating surface 110, thus avoiding hard-to-clean corners during disinfection or cleaning. It also simplifies mold design.

[0045] like Figure 2As shown, in some embodiments, the contact surface 211 may protrude beyond the mating surface 110. An insulating protective portion 111 may be provided on the mating surface 110. The insulating protective portion 111 may be disposed on the outer periphery of the portion of the electrical contact pin 200 protruding from the mating surface 110. The insulating protective portion 111 may be integrally injection molded with the mating surface 110 around the portion of the electrical contact pin 200 protruding from the mating surface 110. The insulating protective portion 111 may be made of a waterproof material such as polyethylene (PE) or polypropylene (PP). When using the endoscope connector 10, the mating surface 110 is typically in a vertical position. Providing the insulating protective portion 111 allows residual liquid on the mating surface 110 to flow down the mating surface 110 without flowing onto the electrical contact pin 200, thus not affecting signal transmission.

[0046] Another aspect of this application provides an endoscope including the endoscope connector 10 of any of the above embodiments. Such an endoscope allows for convenient and safe replacement of parts and disinfection, has better waterproof performance, and the high-precision electrical contact pins 200 that assemble with the insulating base 100 make the endoscope using this endoscope connector 10 less prone to failure.

[0047] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front", "back", "up", "down", "left", "right", "horizontal", "vertical", "horizontal", "top", and "bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0048] For ease of description, relative terms such as "above," "over," "on the upper surface of," and "above" are used here to describe the regional positional relationship of one or more components or features shown in the figures to other components or features. It should be understood that relative terms include not only the orientation of the component as depicted in the figure but also different orientations during use or operation. For example, if the components in the figures are inverted as a whole, "above" or "above other components or features" will include cases where the component is "below" or "under" other components or features. Thus, the exemplary term "above" can include both "above" and "below." Furthermore, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document intends to include all such cases.

[0049] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, parts, components, and / or combinations thereof.

[0050] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar subjects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in sequences other than those illustrated or described herein.

[0051] This application has been described through the above embodiments. However, it should be understood that the above embodiments are for illustrative purposes only and are not intended to limit this application to the scope of the described embodiments. Furthermore, those skilled in the art will understand that this application is not limited to the above embodiments, and many more variations and modifications can be made based on the teachings of this application, all of which fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
