Description

Technical Field

[0001] This utility model relates to the field of cable connection technology, and in particular to a cable connector, cable assembly and detection device. Background Technology

[0002] With the continuous advancement of modern medical diagnostic and treatment technologies, the use of various testing devices (such as endoscopes) to insert into human organs for diagnostic and treatment procedures has become the mainstream approach in clinical practice. Due to their high cost and sophisticated structure, these devices often require multiple uses; therefore, effective sterilization methods are essential to eliminate any remaining microorganisms and avoid the risk of cross-infection. Currently, the mainstream sterilization method for these devices is high-temperature, high-pressure sterilization (HTSA), which achieves reliable sterilization through a high-temperature, high-pressure environment and is widely used in the medical field. The testing device is typically detachably connected to the testing body via a cable connector. To ensure that the precision components inside the testing body are protected from external moisture (especially during high-temperature and high-pressure sterilization), a potting process is commonly used in related technologies to seal the mating parts of the cable and the cable connector. This involves injecting adhesive into the gap formed after the cable passes through the cable connector, and using the sealant effect of the cured adhesive to block the path of moisture into the testing body. However, due to the fundamental difference in materials between the adhesive and the cable connector, their coefficients of thermal expansion differ significantly. During high-temperature and high-pressure sterilization, the asynchronous thermal expansion of the adhesive and the cable connector can create micro-gaps at their interface. This allows moisture to enter the testing unit through these micro-gaps, potentially damaging it. Utility Model Content

[0003] This utility model discloses a cable connector, a cable assembly, and a testing device to solve the problem that the testing body of the testing device in the related technology is easily damaged by moisture during high temperature and high pressure sterilization.

[0004] To solve the above-mentioned technical problems, this utility model is implemented as follows: In a first aspect, this application discloses a cable connector for connecting a cable and a detection body, the cable connector including a connector body, an adapter circuit board, a first sealing ring and a limiting connector; The connector body has a through mounting hole in the first direction. The mounting hole is a stepped hole with a first stepped portion. The adapter circuit board is disposed in the mounting hole and overlaps the first stepped portion to divide the mounting hole into a first hole segment and a second hole segment. The limiting connector is disposed on the connector body and is used to limit and cooperate with the adapter circuit board on the side of the adapter circuit board opposite to the first step portion. The first sealing ring is sealed between the adapter circuit board and the connector body.

[0005] Secondly, this application also discloses a cable assembly, which includes a cable and the cable connector described in the first aspect. The end of the cable passes through the first hole segment and is connected to the adapter circuit board. The side of the first hole segment opposite to the second hole segment is constricted to clamp the cable.

[0006] Thirdly, this application also discloses a testing device, which includes a testing body and the cable assembly described in the second aspect. The testing body includes a housing and a testing component. The housing has a mounting portion, which is an annular structure. The mounting portion is sleeved on the portion of the connector body corresponding to the second hole segment, so that the housing is connected to the connector body.

[0007] The technical solution adopted in this utility model can achieve the following technical effects: This embodiment of the application sets the cable connector to a structure including a connector body, an adapter circuit board, a first sealing ring, and a limiting connector. A through-hole is formed in the connector body along a first direction, and the mounting hole is a stepped hole. The adapter circuit board is placed inside the mounting hole and overlaps the first stepped portion. The limiting connector installs the adapter circuit board onto the first stepped portion, and the first sealing ring seals the connection between the adapter circuit board and the connector body. This allows the adapter circuit board to divide the mounting hole into a first segment and a second segment, creating a sealed isolation. After connecting the cable to the side of the adapter circuit board facing the first segment, and after connecting the detection body to the side of the adapter circuit board facing the second segment, the first and second segments are sealed and isolated by the adapter circuit board and the first sealing ring. This effectively prevents external moisture from entering the second segment from the side of the first segment, thus protecting the detection body from damage caused by external moisture.

Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0011] The technical solutions disclosed in the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0012] Please refer to Figures 1 to 3 This utility model discloses a cable connector for connecting a cable 500 and a detection body. The detection body can be a camera module, an ultrasonic detection module, etc., and this application does not impose specific limitations on the structure of the detection body.

[0013] The cable connector includes a connector body 100, an adapter circuit board 200, a first sealing ring 300, and a limiting connector 400. The connector body 100 is the main component of the cable connector and provides a mounting base for the other components of the cable connector. The adapter circuit board 200 is used to realize the electrical connection between the cable 500 and the detection body.

[0014] The connector body 100 has a mounting hole 110 extending along a first direction. The mounting hole 110 is a stepped hole with a first stepped portion 111. The adapter circuit board 200 is disposed within the mounting hole 110 and overlaps the first stepped portion 111, thereby dividing the mounting hole 110 into a first hole segment 110a and a second hole segment 110b. It should be noted that the first stepped portion 111 is an annular stepped portion, and the adapter circuit board 200 overlapping the first stepped portion 111 means that the circumferential edge of the adapter circuit board 200 overlaps the first stepped portion 111.

[0015] A limiting connector 400 is disposed on the connector body 100 and is used to limit and cooperate with the adapter circuit board 200 on the side of the adapter circuit board 200 opposite to the first step portion 111, so that the adapter circuit board 200 is fixed to the first step portion 111. It should be noted that when it is necessary to disassemble the adapter circuit board 200, the user can operate the limiting connector 400 to separate the limiting connector 400 from the adapter circuit board 200, thereby allowing the adapter circuit board 200 to be disassembled. The specific setting of the limiting connector 400 will be described later and will not be repeated here.

[0016] The first sealing ring 300 is sealed between the adapter circuit board 200 and the connector body 100, thereby achieving a seal between the adapter circuit board 200 and the connector body 100.

[0017] It should be noted that the adapter circuit board 200 in this embodiment is a holeless circuit board. After the adapter circuit board 200 is installed on the first step portion 111 via the limiting connector 400, and the first sealing ring 300 is sealed between the adapter circuit board 200 and the connector body 100, a sealed isolation is achieved between the first hole segment 110a and the second hole segment 110b. The side of the adapter circuit board 200 facing the first hole segment 110a can be used to connect to the cable 500. The cable 500 can enter the first hole segment 110a through the port of the first hole segment 110a facing away from the adapter circuit board 200 and be electrically connected to the adapter circuit board 200. The side of the adapter circuit board 200 facing the second hole segment 110b can be used to connect to the detection body. For example, the detection component of the detection body can be electrically connected to the adapter circuit board 200 through the connecting terminal. Here, the detection component refers to the component used to realize the detection function, such as a lens assembly.

[0018] This embodiment of the application sets the cable connector to a structure including a connector body 100, an adapter circuit board 200, a first sealing ring 300, and a limiting connector 400. A mounting hole 110 extending in a first direction is provided in the connector body 100, and the mounting hole 110 is configured as a stepped hole, so that the adapter circuit board 200 is disposed within the mounting hole 110 and overlaps the first stepped portion 111. The limiting connector 400 installs the adapter circuit board 200 onto the first stepped portion 111, and the first sealing ring 300 seals the connection between the adapter circuit board 200 and the connector body 100, thus ensuring the adapter circuit board 200 is properly seated. The hole 110 is divided into a first hole segment 110a and a second hole segment 110b, which are sealed and isolated. After the cable 500 is connected to the side of the adapter circuit board 200 facing the first hole segment 110a, and after the detection body is connected to the side of the adapter circuit board 200 facing the second hole segment 110b, the first hole segment 110a and the second hole segment 110b are sealed and isolated through the adapter circuit board 200 and the first sealing ring 300. This can effectively prevent external moisture from entering the second hole segment 110b from the side of the first hole segment 110a, thereby protecting the detection body and preventing damage to the detection body from external moisture.

[0019] Specifically, the first sealing ring 300 can seal the connection between the circumferential end face of the adapter circuit board 200 and the connector body 100. In this embodiment, the sealing rings can all be made of a material that is resistant to high temperature and high humidity and has low permeability.

[0020] In another embodiment, the mounting hole 110 may further have a second stepped portion 112, which may be located in the first hole segment 110a. The inner diameter of the second stepped portion 112 may be smaller than the inner diameter of the first stepped portion 111. The first sealing ring 300 may overlap the second stepped portion 112, and the first sealing ring 300 may seal between the second stepped portion 112 and the adapter circuit board 200. It should be noted that the first sealing ring 300 is higher than the first stepped portion 111 in the direction of extension along the central axis of the mounting hole 110.

[0021] The cable connector disclosed in this application has a structure in which the mounting hole 110 is configured to also have a second step portion 112, and the second step portion 112 is located within the first hole segment 110a. This allows the adapter circuit board 200 to be installed on the first step portion 111 via the limiting connector 400, so that the adapter circuit board 200 can compress the first sealing ring 300, causing the first sealing ring 300 to deform. This allows the first sealing ring 300 to be sealed between the adapter circuit board 200 and the second step portion 112, thereby improving the installation stability of the first sealing ring 300.

[0022] Optionally, the first sealing ring 300 may include a positioning portion 310 and an overlapping portion 320. The outer diameter of the overlapping portion 320 may be larger than the outer diameter of the positioning portion 310, so that the positioning portion 310 and the overlapping portion 320 form a T-shaped structure as a whole. The positioning portion 310 and the overlapping portion 320 may be an integral structure. The overlapping portion 320 may overlap the second stepped portion 112, and the positioning portion 310 may extend along the side opposite to the second hole section 110b and fit against the hole wall of the first hole section 110a.

[0023] The cable connector disclosed in this application configures the first sealing ring 300 to include a positioning part 310 and an overlapping part 320, with the outer diameter of the overlapping part 320 being larger than the outer diameter of the positioning part 310. This allows the overlapping part 320 to overlap the second step part 112 during installation of the first sealing ring 300, thereby sealing the overlapping part 320 between the second step part 112 and the adapter circuit board 200. The positioning part 310 can fit against the hole wall of the first hole section 110a, thus enabling the positioning of the first sealing ring 300 and preventing the sealing failure caused by misalignment of the first sealing ring 300 during installation.

[0024] There are relatively many ways to set the limiting connector 400. For example, the limiting connector 400 can be connected to the connector body 100 through a snap-fit ​​assembly. After the limiting connector 400 installs the adapter circuit board 200 on the first step 111, the limiting connector 400 can be fixed to the connector body 100 through the snap-fit ​​assembly. When it is necessary to remove the adapter circuit board 200, simply open the snap-fit ​​assembly.

[0025] In another embodiment, the limiting connector 400 can be a ring structure, and the limiting connector 400 can have external threads, while the second hole section 110b can have internal threads, and the limiting connector 400 can be threadedly engaged with the second hole section 110b. The cable connector disclosed in this application connects the limiting connector 400 and the connector body 100 by means of threaded engagement, making the engagement between the limiting connector 400 and the connector body 100 relatively simple and more stable.

[0026] Optionally, the mounting hole 110 may also have a third step portion 113, which may be located in the second hole segment 110b, and the inner diameter of the third step portion 113 may be larger than the inner diameter of the first step portion 111. The limiting connector 400 may include a clamping portion 410 and a limiting extension portion 420. The clamping portion 410 may be used to clamp the adapter circuit board 200 onto the first step portion 111. The clamping portion 410 may mate with the surface of the adapter circuit board 200 facing away from the first step portion 111 to clamp the adapter circuit board 200 onto the first step portion 111. The limiting extension portion 420 may extend between the end face of the adapter circuit board 200 and the hole wall of the second hole segment 110b to limit the adapter circuit board 200 in the circumferential direction of the second hole segment 110b.

[0027] The cable connector disclosed in this application configures the mounting hole 110 to also have a third step portion 113, with the third step portion 113 located in the second hole segment 110b. The limiting connector 400 is configured to include a pressing portion 410 and a limiting extension portion 420, such that the pressing portion 410 engages with the surface of the adapter circuit board 200 on the side opposite to the first step portion 111, thereby pressing the adapter circuit board 200 onto the first step portion 111 and thus fixing the adapter circuit board 200. The limiting extension portion 420 extends between the end face of the adapter circuit board 200 and the hole wall of the second hole segment 110b, thereby limiting the adapter circuit board 200 in the circumferential direction of the second hole segment 110b, thereby making the installation of the adapter circuit board 200 more stable and the position of the adapter circuit board 200 more accurate.

[0028] To further prevent moisture from entering the second hole section 110b, the connector body 100 may optionally have an injection port 114 and an exhaust port 115 communicating with the first hole section 110a. The injection port 114 can be used to fill the first hole section 110a with sealant, and the exhaust port 115 can be used to expel the air from the first hole section 110a when the sealant is injected into it.

[0029] The cable connector disclosed in this application has an injection port 114 and an exhaust port 115 on the connector body 100 that communicate with the first hole segment 110a. This allows sealant to be filled into the first hole segment 110a through the injection port 114, filling the space between the cable 500 and the inner wall of the first hole segment 110a with sealant. This creates a sealing layer on the side of the adapter circuit board 200 facing the first hole segment 110a, further preventing moisture from entering the second hole segment 110b from the first hole segment 110a.

[0030] Specifically, the detection body may include a housing 610, which may have a mounting portion 611. The mounting portion 611 may be an annular structure, and the inner wall of the mounting portion 611 may have a fourth step portion 612. It should be noted that, except for the mounting portion 611, all other parts of the housing 610 are sealed structures.

[0031] The cable connector may also include an annular connector 700, which is movably fitted outside the connector body 100. The first end of the annular connector 700 may have an abutment portion 710. The outer wall of the connector body 100 may have a fifth step portion 120 and an abutment mating portion 130. The limiting mating surfaces of the fifth step portion 120 and the limiting mating surfaces of the abutment mating portion 130 face opposite directions in the first direction. When the detection body is connected to the connector body 100, the mounting portion 611 may be fitted outside the second hole section 110b. The abutment portion 710 may make limiting contact with the limiting mating surface of the abutment mating portion 130, the limiting mating surface of the fifth step portion 120 may make limiting contact with the fourth step portion 612, and the second end of the annular connector 700 may be connected to the mounting portion 611.

[0032] The cable connector disclosed in this application provides a fifth step portion 120 and an abutment mating portion 130 on the outer wall of the connector body 100. When the detection body is connected to the connector body 100, the mounting portion 611 is sleeved outside the second hole section 110b, the abutment portion 710 is in limiting contact with the limiting mating surface of the abutment mating portion 130, the limiting mating surface of the fifth step portion 120 is in limiting contact with the fourth step portion 612, and the second end of the annular connector 700 is connected to the mounting portion 611. Thus, the connection between the connector body 100 and the detection body can be realized through the annular connector 700.

[0033] To improve the stability of the connection between the connector body 100 and the detection body, optionally, when the detection body and the connector body 100 are connected, the annular connector 700 and the connector body 100 can form an annular insertion groove 701, and the mounting part 611 can have an annular insertion part 611a, which can be inserted into the annular insertion groove 701, thereby making the connection between the connector body 100 and the detection body more stable under the limiting effect of the annular insertion groove 701.

[0034] Optionally, the inner wall of the annular connector 700 may have an internal thread, and the annular insertion portion 611a may have an external thread, which can be threadedly engaged with the annular connector 700. The annular connector 700, through the internal thread engaging with the external thread of the annular insertion portion 611a, makes the connection between the annular connector 700 and the housing 610 of the detection body more stable.

[0035] To prevent external moisture from entering the second hole section 110b from between the connector body 100 and the annular insertion part 611a, optionally, the outer wall of the connector body 100 may be provided with a second sealing ring 810. The second sealing ring 810 can be sealed between the inner wall of the annular insertion part 611a and the outer wall of the connector body 100, thereby preventing external moisture from entering the second hole section 110b from between the connector body 100 and the annular insertion part 611a.

[0036] Optionally, the end of the connector body 100 that extends into the mounting portion 611 may be provided with a third sealing ring 820, and the inner wall of the mounting portion 611 may be provided with a sixth step portion 613. The third sealing ring 820 can be sealed between the end of the connector body 100 that extends into the mounting portion 611 and the sixth step portion 613, thereby further preventing moisture from entering the second hole section 110b from between the connector body 100 and the mounting portion 611.

[0037] This application also discloses a cable assembly, which includes a cable 500 and a cable connector disclosed in the above embodiments. The end of the cable 500 passes through a first hole 110a and is connected to an adapter circuit board 200. The side of the first hole 110a opposite to the second hole 110b is tapered. The side of the first hole 110a opposite to the second hole 110b is used to clamp the cable 500, thereby realizing the assembly of the cable 500 and the cable connector.

[0039] To protect the cable 500, the cable assembly may optionally include a cable protective sleeve 910, which can wrap around the cable 500, and the portion of the cable protective sleeve 910 located on the connector body 100 can also wrap around the connector body 100. The cable assembly disclosed in this application can protect the cable 500 by providing a cable protective sleeve 910 on the outside of the cable 500, and by wrapping the portion of the cable protective sleeve 910 located on the connector body 100 around the connector body 100, the stability of the connection between the cable 500 and the connector body 100 can be improved.
