[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners. Similar elements in different implementation manners are labeled with related similar element numbers. In the following implementation manners, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of these features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification to avoid overwhelming the core part of the present application with excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and general technical knowledge in the art.
[0035] In addition, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. Meanwhile, the steps or actions in the method description can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment and do not mean a necessary sequence, unless it is stated otherwise that a certain sequence must be followed.
[0036] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in this application, unless otherwise specified, both include direct and indirect connection (coupling).
[0037] In the related art, for the endoscope handle and the portable direct display device, a connection form of inserting a gold-plated copper pin at one end into a gold-plated copper tube at the other end is mostly used to build a signal channel. The above connection form requires an interference fit between the copper pin and the copper tube to ensure sufficient contact and stable signal transmission.
[0038] However, in the above connection method, centering is usually achieved by inserting and plugging the copper pin into the copper tube. During long-term use, due to the repeated insertion and extraction of the copper pin and the copper tube, stress is likely to occur at the connection between the copper pin, the copper tube, and the plastic seat, which easily leads to a gap at the connection between the copper pin, the copper tube, and the plastic seat. This gap will connect the inner cavity of the endoscope handle to the outside, resulting in the non-sealing of the endoscope handle. Pollutants are likely to enter the inner cavity of the endoscope handle through the gap and are not easily cleaned.
[0039] In addition, repeated insertion and extraction will cause wear of the copper pin and the copper tube, resulting in the problem of image signal distortion due to insufficient contact. It should also be noted that when there are many signal channels output from the endoscope handle, multiple copper pins and copper tubes with smaller diameters are required, which are prone to deformation and have a high requirement for the positioning accuracy of the docking head.
[0040] To solve the above problems, it can be considered to directly dock the first conductive terminal on the portable direct display device with the docking end face of the second conductive terminal on the endoscope handle, avoiding the wear of the copper pin and the copper tube in the plugging method and the stress at the connection with the plastic seat. Additionally, a positioning structure and a locking structure are provided to realize the connection between the portable direct display device and the endoscope handle.
[0041] As Figures 1 - 6 shown, in one embodiment, a joint assembly is provided, including a first joint and a second joint. Among the first joint and the second joint, one can be applied to the endoscope handle 1 of the endoscope device, and the other can be applied to the portable direct display device 2 of the endoscope device, or a transfer wire 3 for connecting the endoscope handle 1 and the display device (not shown in the figure).
[0042] As shown Figure 4 in Figure 4 , the first connector includes a first terminal assembly 4, a connector housing 5, and a rotating housing. The first terminal assembly 4 includes a plurality of first conductive terminals 41, a first terminal base 42, and a wire body 43. The plurality of first conductive terminals 41 are arranged on the first terminal base 42, and the wire body 43 can be connected to the tails of the first conductive terminals 41 by welding. Specifically, the wire body 43 can be the main wire of a patch cord or the internal connection wire of a portable direct display device.
[0043] As shown Figure 9 in Figure 9 , the connector housing 5 has a first inner hole 51, and the first conductive terminals 41 are disposed in the first inner hole 51. Specifically, a stop step can be provided in the first inner hole 51 to limit the upward movement of the first terminal base 42 and prevent the first terminal base 42 from disengaging from the connector housing 5 upward. The first terminal base 42 can be columnar, and an anti-rotation plane is provided on the outer peripheral surface. Correspondingly, a plane is also provided on the inner wall of the first inner hole 51. Through the setting of the anti-rotation plane, the first terminal base 42 cannot rotate relative to the connector housing 5. In addition, positioning holes can be provided on the wall surface of the first inner hole 51, and positioning protrusions can be provided on the outer wall of the first terminal base 42. The positioning protrusions can be snapped into the positioning holes to make it difficult for the first terminal base 42 to move downward and disengage from the connector housing 5.
[0044] As shown Figure 7 and Figure 8 in Figure 8 , the rotating housing is disposed on the outer periphery of the connector housing 5 and forms an annular docking space with the connector housing 5. The docking space is used to accommodate the docking housing 10 of the second connector. The rotating housing can rotate relative to the connector housing 5. The rotating housing is provided with an L-shaped groove 61, and the L-shaped groove 61 has an opening facing the docking housing 10. The opening is used for the locking post 102 on the docking housing 10 to enter or exit the L-shaped groove 61.
[0045] As shown Figure 5 in Figure 5 , the second connector includes a second terminal assembly 9 and a docking housing 10. The second terminal assembly 9 includes second conductive terminals 91, and the second conductive terminals 91 are used to dock with the first conductive terminals 41. The docking housing 10 is provided with a second inner hole 101, and the second conductive terminals 91 are disposed in the second inner hole 101. The docking housing 10 is used to be assembled in the docking space to dock with the connector housing 5, and a protruding locking post 102 is provided on the outer wall of the docking housing 10.
[0046] After docking the docking housing 10 with the joint housing 5, the rotating housing has an unlocking position and a locking position during rotation. At the unlocking position, the locking post 102 is located within the L-shaped groove 61 and aligned with the opening of the L-shaped groove 61. At this time, the locking post 102 can withdraw from the L-shaped groove 61 to separate the first joint from the second joint. At the locking position, the locking post 102 is offset from the opening of the L-shaped groove 61 and abuts against the groove wall of the L-shaped groove 61 to prevent the docking housing 10 from axially disengaging from the joint housing 5.
[0047] In some embodiments, such as Figure 4 and Figure 7 shown, the end of the first conductive terminal 41 for docking with the second conductive terminal 91 can be telescopic. Specifically, the first conductive terminal 41 may include a main body portion, a contact head, and an elastic member. The main body portion is provided with a sliding cavity, the elastic member is disposed within the sliding cavity, and the contact head is assembled within the sliding cavity and can be telescopic relative to the main body portion under the action of the elastic member.
[0048] The second terminal assembly 9 includes a second conductive terminal 91 and a second terminal seat 92. A plurality of second conductive terminals 91 are disposed on the second terminal seat 92. The second conductive terminal 91 is provided with a docking end face, and the docking end face is flush with the terminal seat. The first conductive terminal 41 is docked with the second conductive terminal 91 through the docking end face. When the first joint is docked with the second joint, the telescopic contact head of the first conductive terminal 41 can abut against the docking end face of the second conductive terminal 91. The setting of the telescopic contact head can compensate for the deviation in the insertion depth of the joint and reduce the requirements for the positioning and assembly accuracy of the joint.
[0049] Compared with the docking methods of copper pins and copper tubes, the above docking method avoids friction, wear, and deformation caused by large-area interference contact, and increases the service life of the joint. At the same time, the docking end face of the second conductive terminal 91 has a certain area, and the contact head of the first conductive terminal 41 can form a signal path when contacting at any position on the docking end face of the second conductive terminal 91, reducing the requirements for the positioning accuracy of the joint.
[0050] Furthermore, in the above docking method, the conductive terminal only serves to connect the signal, and the fixation of the first joint and the second joint is achieved through the rotating housing 7 and the docking housing 10. The connection between the conductive terminal and the first terminal seat 42 is not prone to generating stress perpendicular to the direction of the conductive terminal, and the connection between the conductive terminal and the first terminal seat 42 is not prone to generating gaps, ensuring good sealing of the endoscope device, and preventing pollutants from entering, which is beneficial for cleaning and disinfection.
[0051] In some embodiments, such as Figure 4 and Figure 10As shown, the rotating housing includes an inner housing 6 and an outer housing 7. The outer housing 7 is disposed on the outer periphery of the inner housing 6 and is non-rotatably assembled with the inner housing 6. An L-shaped groove 61 is provided on the inner housing 6. There are various ways of non-rotatably assembling. For example, in the inner housing 6 and the outer housing 7, one is provided with a non-rotating block 62, and the other is provided with a non-rotating groove 72 adapted to the non-rotating block 62. In this embodiment, a flange 71 is provided on the inner side of the outer housing 7, and three non-rotating grooves 72 are provided on the flange 71. The three non-rotating grooves 72 are arranged at intervals along the circumferential direction of the outer housing 7. Correspondingly, three non-rotating blocks 62 are provided on the inner housing 6, and the non-rotating blocks 62 are fitted in the non-rotating grooves 72.
[0052] In other embodiments, it is also possible to provide a non-rotating groove 72 on the inner housing 6 and a non-rotating block 62 adapted thereto on the outer housing 7.
[0053] In some embodiments, such as Figure 4 and Figure 9 As shown, the first joint includes a reset member 8. The reset member 8 is connected between the joint housing 5 and the inner housing 6 and is used to drive the inner housing 6 to move from the locked position to the unlocked position. Specifically, the reset member 8 can be a reset torsion spring. The reset torsion spring is sleeved on the joint housing 5, with one end fixed to the joint housing 5 and the other end fixed to the inner housing 6.
[0054] The reset torsion spring can be arranged as follows: A fixing hole 52 is provided on the joint housing 5. One end of the reset torsion spring has a first bending portion facing the joint housing 5, and the first bending portion is inserted into the fixing hole 52. A circumferentially extending fixing groove 63 is provided on the inner housing 6. The other end of the reset torsion spring is provided with an axially extending second bending section, and the second bending section is assembled in the fixing groove 63.
[0055] In some embodiments, such as Figure 8 As shown, the first joint includes an elastic limiting member 64. The elastic limiting member 64 includes a limiting convex portion and a main body portion. The main body portion is located on one side of the L-shaped groove 61 and is fixed to the inner housing 6. Specifically, two bosses 65 can be provided on the inner housing 6, and the main body portion of the elastic limiting member 64 is sleeved on the bosses 65. The limiting convex portion protrudes toward the inside of the L-shaped groove 61 to limit the locking post 102 on the right side of the L-shaped groove 61, that is, the bottom of the L-shaped groove 61.
[0056] The elastic limiting member 64 is provided such that the rotating housing cannot rotate from the locked position to the unlocked position under the action of the reset member 8. Under the action of an external force, for example, manually rotating the outer shell 7, the limiting convex portion can deform towards the main body portion under the action of the locking post 102 and disengage from the L-shaped groove 61. At this time, the limiting convex portion releases the limitation on the locking post 102, and the locking post 102 can move to the opening of the L-shaped groove 61. Similarly, when the locking post 102 moves from the opening of the L-shaped groove 61 to the bottom of the L-shaped groove 61, the limiting convex portion will also deform. In addition, the elastic limiting member 64 is provided such that when the user rotates the outer shell 7, the deformation feedback of the limiting convex portion can be received.
[0057] In some embodiments, as Figure 10 shown, a stroke limiting groove is provided on the outer shell 7. Specifically, a flange 71 is provided on the inner side of the outer shell 7, and a first stop block 73 and a second stop block 74 are provided on the flange 71. The first stop block 73 and the second stop block 74 are arranged at intervals along the circumferential direction of the outer shell 7, and the stroke limiting groove is formed between the first stop block 73 and the second stop block 74. A convex block 53 is provided on the joint housing 5, and the convex block 53 is located in the stroke limiting groove and can move in the stroke limiting groove. The stroke limiting groove is used to limit the rotation stroke of the outer shell 7 and the inner shell 6.
[0058] In some embodiments, as Figure 4 shown, at least two L-shaped grooves 61 are provided on the inner shell 6, and at least two locking posts 102 are provided on the docking housing 10. The L-shaped grooves 61 and the locking posts 102 are in one-to-one correspondence. The provision of multiple L-shaped grooves 61 and locking posts 102 makes the connection between the first joint and the second joint more stable.
[0059] In some embodiments, as Figure 4 shown, two L-shaped grooves 61 are provided on the inner shell 6, and the two L-shaped grooves 61 are arranged in a 180° rotation about the axis of the inner shell 6. The widths of the two L-shaped grooves 61 are different. Two locking posts 102 are provided on the docking housing 10, and the diameters of the two locking posts 102 are different. The two L-shaped grooves 61 respectively correspond to the two locking posts 102. The locking post 102 with a larger diameter cannot enter the L-shaped groove 61 with a smaller width. The purpose of the above setting is to prevent the docking angle between the first joint and the second joint from being incorrect.
[0060] In some embodiments, as Figure 4 and Figure 5 shown, a flat position 54 is provided at the position where the joint housing 5 is docked with the docking housing 10. Correspondingly, a flat position 54 is also provided on the inner side of the docking housing 10. When the joint housing 5 is docked with the docking housing 10, positioning is performed through the flat position 54.
[0061] In some embodiments, as Figure 4As shown, the outer periphery of the joint housing 5 is axially and sequentially provided with a first annular flange 55, a second annular flange 56 and a threaded section 57 at intervals. The first joint further includes a fixing nut 58 which is connected to the threaded section 57. The outer housing 7 is axially limited between the first annular flange 55 and the inner housing 6, and the inner housing 6 is axially limited between the outer housing 7 and the fixing nut 58. Specifically, a flange 71 is provided on the inner side of the outer housing 7, and the top of the inner housing 6 abuts against the flange 71.
[0062] The assembly process of the first joint is as follows: The first terminal seat 42 is inserted into the first inner hole 51 from the lower side of the joint housing 5; the reset member 8 is sleeved on the joint housing 5 from the lower side; the elastic limiting member 64 is installed on the boss 65 of the inner housing 6; the inner housing 6 is inserted into the outer housing 7 from the lower side of the outer housing 7; the inner housing 6 and the outer housing 7 are integrally sleeved on the joint housing 5 from the lower side of the joint housing 5, and during this process, the second bent section of the reset member 8 is assembled with the inner housing 6; the fixing nut 58 is installed on the threaded section 57 from the lower side of the joint housing 5, and the assembly of the first joint is completed. After installation, the inner housing 6 and the outer housing 7 are fixed and can rotate relative to the joint housing 5.
[0063] The docking process of the joint assembly of the present invention is as follows: The docking housing 10 is inserted into the annular space. During this process, the docking housing 10 and the joint housing 5 can be positioned by the flat position 54; after the docking housing 10 is inserted in place, the locking post 102 is located at the opening of the L-shaped groove 61, that is, the unlocking position; the outer housing 7 is rotated so that the locking post 102 crosses the elastic limiting member 64 to reach the bottom of the L-shaped groove 61, that is, the locking position, and the first joint and the second joint are completed for docking. When it is necessary to disassemble the first joint and the second joint, first rotate the outer housing 7 in the reverse direction so that the locking post 102 crosses the elastic limiting member 64 to reach the opening of the L-shaped groove 61, and then pull out the second joint.
[0064] The endoscope device of the embodiment of the present invention is described below.
[0065] As Figure 1 and Figure 2 shown, the endoscope device of the embodiment of the present invention includes a joint assembly as in any of the above embodiments, an endoscope handle 1 and a portable direct display device 2. The endoscope handle 1 applies the second joint of the joint assembly; the portable direct display device 2 applies the first joint of the joint assembly.
[0066] In other embodiments, as Figure 1 and Figure 3 shown, the endoscope device of the embodiment of the present invention includes a joint assembly as in any of the above embodiments, an endoscope handle 1, a transfer wire 3 and a display device (not shown in the figure). The endoscope handle 1 applies the second joint of the joint assembly; the transfer wire 3 applies the first joint of the joint assembly and is connected between the endoscope handle 1 and the display device.
