Description

Technical Field

[0001] The utility model relates to the technical field of endoscopes, in particular to a connector, an endoscope and an endoscope system. Background Art

[0002] The working principle of existing endoscopes is to insert them into the human body through the natural or artificially constructed cavities for inspection or treatment. When the endoscope is inserted into the human body, it needs to use a lens and a light source system to observe the internal situation, or it needs to use an instrument channel to introduce liquid (such as saline) for washing, or use a suction device to absorb liquid and tissue samples. In order to achieve the above functions, the endoscope and the relevant host equipment are connected to each other through various functional connectors to form an endoscope system to obtain light source, water source, negative pressure source and power source, and transmit signals.

[0003] Some endoscopes in the related art integrate multiple connectors into one connector in order to reduce the number of connectors, simplify the structure, and improve the convenience of plugging (multiple connectors can be docked in one plug). However, integrating multiple connectors on one connector will lead to excessive concentration of connectors, which increases the risk of connector damage (for example, if one of the connectors on the connector is damaged, the entire connector will be damaged).

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0050] On the one hand, the present application provides a connector that can effectively reduce the risk of damage to a connector that integrates multiple connectors, such as Figure 1-Figure 8 As shown, it is particularly configured as follows:

[0051] The connector 10 in this embodiment is used for an endoscope to connect the endoscope to a host device to realize related functions.

[0052] In this embodiment, the connector 10 can realize the ventilation, power supply and light guiding functions of the endoscope through one-time plugging and unplugging.

[0053] like Figure 1-Figure 8 As shown, the connector 10 includes a housing 11 and an electrical connector 12, an air path head 13 and a light guide rod 14 which are integrated and connected to the housing 11. The electrical connector 12, the air path head 13 and the light guide rod 14 are used to respectively connect with the power supply and signal interface, the air source interface and the light source interface adapted to the host device, so that the endoscope can realize the ventilation, power supply and light guide functions.

[0054] like Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, the housing 11 has an outer peripheral surface enclosed around an axis, and the direction of the axis is the housing 11, that is, the docking direction of the connector 10 and the female socket of the host device. The housing 11 also includes a docking end face 111 arranged at its docking end and perpendicular to its axis, and a tail sleeve arranged at one end away from the docking end face 111. The housing 11 is provided with a protective portion 112 on the docking end face 111, and the protective portion 112 protrudes from the docking end face 111 along the axial direction of the housing 11, and encloses a mounting area 113 along the circumference of the docking end face 111.

[0055] The installation area 113 may be closed on all sides, in which case the protection portion 112 is a wall that is closed along the circumference of the butt end surface 111. Of course, the installation area 113 may also be open, in which case the protection portion 112 may be as shown in FIG. Figure 2 and Figure 6 As shown, it is composed of a plurality of vertical walls 112a arranged in sequence along the circumference of the butt end surface 111 (ie around the axis of the housing 11). Gaps are formed between adjacent vertical walls 112a.

[0056] The electrical connector 12, the gas circuit connector 13 and the light guide rod 14 are distributed on the butt end surface 111. Specifically:

[0057] The electrical connector 12 is disposed inside the mounting area 113 and fixedly connected to the housing 11 . The electrical connector 12 protrudes from the butt end surface 111 along the axial direction of the housing 11 .

[0058] The gas circuit head 13 is disposed inside the installation area 113 and fixedly connected to the housing 11 . The gas circuit head 13 protrudes from the butt end face 111 along the axial direction of the housing 11 .

[0059] The light guide rod 14 is arranged inside the installation area 113 and fixedly connected to the shell 11. The light guide rod 14 protrudes from the docking end face 111 along the axial direction of the shell 11; wherein the free end of the protective portion 112 is flush with or exceeds the free ends of the electrical connector 12 and the gas path head 13.

[0060] Generally, the length of the light guide rod 14 protruding from the butt end face 111 is longer than that of the electrical connector 12 and the gas circuit head 13, while the lengths of the electrical connector 12 and the gas circuit head 13 protruding from the butt end face 111 are similar. Figure 1 , Figure 2 , Figure 4-Figure 6 and Figure 8 It can be seen in.

[0061] Depending on the host device, the housing 11 may be Figure 1-Figure 5 The roughly cylindrical housing in the embodiment may also be Figure 6-Figure 8The substantially flat cylindrical housing 11 is a flat structure, which can achieve smaller size and lighter structure under the premise of realizing the function, but puts forward more requirements for the internal device layout than the cylindrical housing 11.

[0062] In this embodiment, the electric connector 12, the gas circuit head 13 and the light guide rod 14 are integrated in one connector 10, so that the connector 10 can realize the on and off of gas, electricity and light at the same time through one plugging and unplugging. On the docking end face 111 of the shell 11, a protective part 112 protruding from the docking end face 111 is arranged on the periphery of the electric connector 12, the gas circuit head 13 and the light guide rod 14, and the free end of the protective part 112 is flush with or exceeds the free end of the electric connector 12 and the gas circuit head 13, which improves the protective effect of the electric connector 12, the gas circuit head 13 and the light guide rod 14, reduces the risk of the electric connector 12, the gas circuit head 13 and the light guide rod 14 being damaged by collision, and thus reduces the risk of damage to the connector. At the same time, the protective part 112 protrudes from the docking end face 111 along the axial direction of the shell 11, and can interact with the shell of the female socket during the plugging process of the shell 11 and the female socket of the host device, play a guiding role, guide the connector 10 to dock with the female socket of the host device smoothly, and improve the plugging efficiency.

[0063] According to some optional embodiments, Figure 3 and Figure 7 As shown, the gas circuit head 13, the electric connector 12 and the light guide rod 14 are arranged in sequence along a straight line, so that the electric connector 12 is located between the gas circuit head 13 and the light guide rod 14. Since the electric connector 12 needs more protection than the gas circuit head 13 and the light guide rod 14, this layout can further use the gas circuit head 13 and the light guide rod 14 as a lateral protection structure of the electric connector 12, thereby improving the protection capability of the electric connector 12.

[0064] According to some optional embodiments, in order to allow the electric connector 12 to have more functions, an electric connector 12 of a larger size (with more electrical connections) is required. In order to set an electric connector 12 of a larger size, a sufficiently large layout gap needs to be maintained between the air path head 13 and the light guide rod 14 and the electric connector 12.

[0065] One situation is that Figure 3 As shown, the gas circuit head 13, the electric connector 12 and the light guide rod 14 are arranged in sequence along a straight line, the electric connector 12 is arranged at the center of the butt end surface 111, and the gas circuit head 13 and the light guide rod 14 are arranged symmetrically relative to the electric connector 12. In this case, the outer shell 11 is set to be cylindrical, which is only one of the feasible ways. It can be set as follows Figure 6-Figure 8 The housing 11 is shown in a flat cylindrical shape.

[0066] Another situation is that Figure 7As shown, the gas circuit head 13, the electrical connector 12 and the light guide rod 14 are arranged in sequence along a straight line, and the electrical connector 12 is arranged on one side of the gas circuit head 13 which is smaller than the light guide rod 14. In this case, the housing 11 is set in a flat column shape, which is only one of the feasible ways. It can also be set as follows Figure 1-Figure 3 The housing 11 is shown as being cylindrical.

[0067] It should be noted that, generally, the circumferential dimension of the light guide rod 14 is larger than that of the gas circuit head 13. However, if the circumferential dimension of the gas circuit head 13 is larger than that of the light guide rod 14, the electrical connector 12 should be arranged on one side of the light guide rod 14. When the circumferential dimension of the gas circuit head 13 is equal to that of the light guide rod 14, the electrical connector 12 should be located at the center of the butt end face 111, and the gas circuit head 13 and the light guide rod 14 should be arranged symmetrically relative to the electrical connector 12.

[0068] The above two settings of the position of the electrical connector 12 can make the gap between the electrical connector 12 and the gas circuit head 13 and the light guide rod 14 sufficiently large, and a larger and more functional electrical connector 12 can be set to expand more application scenarios.

[0069] Preferably, reference Figure 3 and Figure 7 , the air path head 13 and the light guide rod 14 are arranged near the circumference of the butt end face 111. Specifically, the air path head 13 and the light guide rod 14 are arranged as close to the circumference of the butt end face 111 as possible while ensuring that the protective part 112 provides sufficient protection for the air path head 13 and the light guide rod 14. In this way, the space around the electric connector 12 can be large enough to be able to set a larger electric connector 12 with richer functions, so as to expand more application scenarios.

[0070] According to some optional embodiments, Figure 1-Figure 5 As shown, the electrical connector 12 is configured as a plate-shaped circuit board, and a portion of the circuit board protruding from the mating end surface 111 is provided with a plurality of conductive contact pieces 121 arranged in sequence along the width direction of the circuit board.

[0071] Preferably, Figure 3 As shown, the board width direction of the circuit board is perpendicular to the arrangement direction of the gas circuit head 13, the electrical connector 12 and the light guide rod 14. The electrical connector 12 of the circuit board is set to make the board width direction perpendicular to the arrangement direction of the gas circuit head 13, the electrical connector 12 and the light guide rod 14, avoiding the arrangement path of the gas circuit head 13 and the light guide rod 14, and can make full use of the space in the installation area 113, arrange a wider circuit board, obtain richer functions, and expand more application scenarios.

[0072] According to some optional embodiments, Figure 6 and Figure 7As shown, the electrical connector 12 is configured as a connector consisting of a plurality of pins.

[0073] Preferably, Figure 6 and Figure 7 As shown, in order to improve the protection effect of the pin pins, a sleeve 122 that conforms to the shape of the pin pin layout is provided on the butt end surface 111, and the sleeve 122 exceeds the pin pins and surrounds all the pin pins.

[0074] According to some optional embodiments, the protection portion 112 includes at least three vertical walls 112 a , and the roots of the vertical walls 112 a are fixedly connected to the butt end surface 111 , preferably by integral injection molding.

[0075] Preferably, the protection portion 112 includes four vertical walls 112 a, which can not only make the housing 11 have a smaller weight, but also provide sufficient protection for the electrical connector 12 , the gas circuit head 13 and the light guide rod 14 .

[0076] like Figure 1-Figure 3 , Figure 6 and Figure 7 As shown, all the vertical walls 112a are arranged equidistantly along the circumference of the butt end surface 111. The electrical connector 12, the gas path head 13 and the light guide rod 14 are all located on the connecting line L ( Figure 3 and Figure 7 The side close to the center of the butt end face 111 (indicated by a dotted line in FIG. 1 ).

[0077] In this embodiment, the multiple independently arranged vertical walls 112a can reduce the weight and manufacturing difficulty of the housing 11 while ensuring the protective effect of the electric connector 12, the gas circuit head 13 and the light guide rod 14. The electric connector 12, the gas circuit head 13 and the light guide rod 14 are all located on the side of the line L on the opposite sides between the outer side surfaces of the adjacent vertical walls 112a close to the center of the butt end surface 111, which can effectively reduce the possibility of the electric connector 12, the gas circuit head 13 and the light guide rod 14 colliding with the outside, because for example, when the connector 10 falls to the ground, the two adjacent vertical walls 112a contact the ground at the same time, and the opposite sides between their outer side surfaces contact the ground at the same time. As long as the electric connector 12, the gas circuit head 13 and the light guide rod 14 are located on the side of the line L close to the center of the butt end surface 111, it can be ensured that the electric connector 12, the gas circuit head 13 and the light guide rod 14 will not directly collide with the ground.

[0078] According to some optional embodiments, Figure 3 and Figure 7As shown, the protection part 112 includes four vertical walls 112a, the gas circuit head 13, the electrical connector 12 and the light guide rod 14 are arranged in sequence along a straight line, and the gas circuit head 13 and the light guide rod 14 are respectively arranged near the periphery of the docking end surface 111 and are arranged in the center position between adjacent vertical walls 112a.

[0079] In this embodiment, the air circuit head 13 and the light guide rod 14 are respectively arranged at the center position between adjacent vertical walls 112a, so that the air circuit head 13 and the light guide rod 14 can be arranged closer to the peripheral edge of the docking end face 111, so as to make fuller use of the installation area 113 for setting, and provide a larger setting space for the electrical connector 12.

[0080] According to some optional embodiments, Figure 2 As shown, an anti-stupidation and anti-rotation structure 1123 is provided on the outer peripheral surface of one of the vertical walls 112a.

[0081] Preferably, the anti-stupidation and anti-rotation structure 1123 is configured as a groove formed on the outer side surface of the vertical wall 112a and extending from the free end of the vertical wall 112a to the docking end surface 111 along the axial direction of the shell 11.

[0082] In this embodiment, the anti-stupidity and anti-rotation structure 1123 is provided on the vertical wall 112a, so that the vertical wall 112a can realize the functions of guiding, anti-stupidity, limiting, and anti-rotation with one structure, which can effectively simplify the shell structure and reduce costs. At the same time, after the anti-stupidity and anti-rotation structure 1123 is provided on the vertical wall 112a, it is not necessary to separately provide the anti-stupidity and anti-rotation related structure on the outer circumference of the light guide rod 14, which can provide anti-rotation protection and reduce the axial size of the light guide rod 14.

[0083] According to some optional embodiments, Figure 1 , Figure 2 and Figure 4-Figure 6 As shown, the outer side of the vertical wall 112a includes a vertical surface 1121 and a slope 1122 connected in sequence along the axial direction of the housing 11. The vertical surface 1121 is connected to the outer peripheral surface of the housing 11 and is arranged flush, so that the vertical surface 1121 is an arc surface. The slope 1122 is inclined toward the installation area 113 in a direction away from the docking end surface 111. After the slope 1122 is arranged on the vertical wall 112a, the housing 11 can be better guided to align with the female socket of the host device to successfully complete the mating.
