[0002] Data cables are commonly used data transmission tools; for example, when viewing a diseased area through an endoscope, image data is acquired through the endoscope's camera, and the signal data is then transmitted through the data cable to the endoscope's image processor device for decoding, and the image processor then transmits the picture information to the video playback device.

[0003] The data line and the image processor are connected through a signal transfer structure, which includes a plug and a socket that fit together. The tightness and reliability of the plug and socket directly affect the stability of data transmission. Most existing plugs are directly inserted into the socket. This connection method is prone to loosening of the plug, affecting the stability of data transmission. Utility Model Content

[0015] Furthermore, two opposite inner side walls of the installation cavity are respectively provided with a board limit groove, and the opposite sides of the gold finger board are respectively inserted into the two board limit grooves.

[0016] Furthermore, one end of the gold finger board located in the installation cavity is fixed on the plug housing; both the groove wall surfaces and the groove bottom surface on both sides of the board limiting groove have a gap with the gold finger board.

[0017] Furthermore, two protection plates are arranged on one end surface of the plug housing, and one end of the gold finger board extending from the installation cavity is located between the two protection plates.

[0042] It should be noted that in the description of the present invention, the terms "connection" and "installation" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through an intermediate medium; it can be a mechanical connection or an electrical connection.

[0043] Reference Figure 1 , the first embodiment of the utility model provides a signal switching structure, which includes a plug 1 and a socket 2;

[0044] A limiting groove 111 is provided on the outer peripheral surface of the plug 1;

[0045] The socket 2 is provided with an adapter slot 21 for inserting the plug 1 therein, and a limiting structure 22 is provided on the slot wall of the adapter slot 21 . The limiting structure 22 can be extended into the adapter slot 21 and inserted into the limiting slot 111 in a telescopic manner.

[0046] When the plug 1 needs to be inserted into the socket 2, the plug 1 is pushed in from the notch of the adapter slot 21. Since one end of the limiting structure 22 can be extended into the adapter slot 21 telescopically, the end of the limiting structure 22 extending into the adapter slot 21 will be lifted up by the plug 1 as the plug 1 is pushed in, so as not to affect the plugging of the plug 1 and the socket 2. When the plug 1 and the socket 2 are plugged in and aligned, one end of the limiting structure 22 is inserted into the limiting groove 111 on the outer surface of the plug 1. In the above structure, the relative position of the plug 1 and the socket 2 can be limited to a certain extent through the plug-in cooperation of the limiting structure 22 and the limiting groove 111, so as to prevent the plug 1 from being loosened or even pulled out when subjected to external forces such as misoperation, thereby ensuring the stability and reliability of data transmission.

[0047] Reference Figure 2 The number of the limiting structures 22 is multiple, and the multiple limiting structures 22 are distributed along the circumference of the socket 2. The provision of multiple limiting structures 22 can limit the plug 1 at multiple positions, further improving the reliability of the plug-in fit between the plug 1 and the socket 2; on the other hand, when the plug 1 is pushed into the socket 2, the multiple limiting structures 22 distributed along the circumference of the socket 2 can generate a centering force on the plug 1, thereby facilitating the plug 1 and the socket 2 to be plugged and unplugged in the center, thereby improving the service life of the signal transfer structure.

[0048] On the basis of the above structure, at least one limiting structure 22 is provided on any one of the slot walls of the adapter slot 21. Exemplarily, the cross-sectional profile of the adapter slot 21 is rectangular, and two limiting structures 22 are provided on the two wider slot walls of the adapter slot 21, and one limiting structure 22 is provided on the two narrower slot walls of the adapter slot 21; through the six limiting structures 22, on the one hand, the relative position of the plug 1 and the socket 2 can be limited to a certain extent, avoiding the problem of unstable data transmission caused by the looseness of the plug 1, and on the other hand, the plug 1 and the socket 2 can be centered in the process of inserting or removing the plug 1 from the socket 2, avoiding the phenomenon of the plug 1 and the socket 2 being misaligned during insertion and removal, thereby improving the durability of the signal adapter structure.

[0049] As an optional embodiment, the plug 1 has multiple outer side surfaces, and the multiple outer side surfaces are arranged corresponding to the multiple groove walls of the adapter slot 21. At least one limiting groove 111 is arranged on any one of the outer side surfaces of the plug 1, and the limiting structure 22 on a groove wall of the adapter slot 21 can be inserted into the corresponding limiting groove 111 on the outer side surface of the plug 1.

[0050] In this embodiment, the limiting structure 22 is a ball plunger, which can be fixed on the groove wall of the adapter slot 21 by screw connection or interference fit; the limiting structure 22 can specifically use a hexagonal cylindrical ball plunger. The ball plunger is a standard part with the advantages of low cost, easy disassembly and assembly, high elasticity and slow force attenuation, etc. It can be purchased in batches without separate processing.

[0051] In other embodiments, the limiting structure 22 includes a locking member and an elastic member, one end of the locking member extends into the adapter slot 21, and the other end of the locking member abuts against the elastic member; optionally, the locking member can be a marble or a pin, and the elastic member can be a compression spring or a spring washer.

[0052] Reference Figure 1 and Figure 2 The socket 2 also includes a fixing sleeve 23 disposed on the outer circumference of the socket 2, and the limiting structure 22 is inserted into the fixing sleeve 23. The fixing sleeve 23 can limit the position of the limiting structure 22, prevent the limiting structure 22 from shaking, and avoid the problem of limiting failure.

[0053] When there are multiple limiting structures 22 , the number of fixing sleeves 23 is also set to be multiple accordingly, and the multiple fixing sleeves 23 are respectively arranged corresponding to the multiple limiting structures 22 , and each limiting structure 22 is inserted into the corresponding fixing sleeve 23 .

[0054] Reference Figure 2 and Figure 3 The plug 1 includes a plug housing 11 and a gold finger board 12, and an assembly board 24 is provided at the bottom of the adapter slot 21;

[0055] An installation cavity 112 is formed in the plug housing 11, one end of the gold finger board 12 along the axial direction of the plug 1 is installed in the installation cavity 112, and the other end of the gold finger board 12 along the axial direction of the plug 1 extends out of the installation cavity 112 and can be plugged with the assembly board 24. In this embodiment, the limit groove 111 is specifically set on the plug housing 11.

[0056] Some signal transfer structures, such as aviation plugs, use welding between wires and terminals, which is affected by the welding process and has a high failure rate. The present application realizes data transmission through the gold finger board 12 and the assembly board 24, which can effectively avoid welding defects and improve data transmission stability.

[0057] Reference Figure 4 Two protective plates 113 are arranged on one end surface of the plug housing 11, and one end of the gold finger board 12 extending from the installation cavity 112 is located between the two protective plates 113. The two protective plates 113 can protect the end of the gold finger board 12 extending from the installation cavity 112, thereby preventing the gold finger board 12 from being damaged by collision.

[0058] Reference Figure 4 and Figure 5 , two opposite inner side walls of the installation cavity 112 are respectively provided with a card limiting groove 1121, and the opposite sides of the gold finger card 12 are respectively inserted into the two card limiting grooves 1121. In the above structure, the card limiting grooves 1121 can limit the position of the gold finger card 12 in the installation cavity 112.

[0059] On the basis of the above structure, one end of the gold finger board 12 located in the installation cavity 112 is fixed to the plug housing 11; the groove walls and the groove bottom of the board limit groove 1121 on both sides have a gap with the gold finger board 12. In this embodiment, one end of the gold finger board 12 located in the installation cavity 112 is provided with a fixing hole 121 for fasteners such as screws to pass through, and one end of the gold finger board 12 is fixed to the plug housing 11 through the fastener and the fixing hole 121.

[0060] Analyzing the above structure, only one end of the gold finger board 12 located in the plug housing 11 is fixed, and the end extending from the plug housing 11 is not fixed. At the same time, the board limit slot 1121 reserves the activity of the gold finger board 12, so the end of the gold finger board 12 extending from the plug housing 11 can be slightly adjusted adaptively. When the gold finger board 12 is docked with the assembly board 24, it may not be firmly docked due to the influence of assembly factors. If the gold finger board 12 is installed in a completely fixed manner, if there is a slight deviation, the gold finger board 12 will not be inserted into the assembly board 24, affecting the use.

[0061] As an optional embodiment, the periphery of the end of the plug housing 11 that can be inserted into the adapter slot 21 is provided with a chamfer;

[0062] And / or, the periphery of the slot of the adapter slot 21 is provided with a chamfer;

[0063] And / or, the assembly board 24 has a board slot for plugging and mating with the gold finger board 12, and the periphery of the notch of the board slot is provided with a chamfer.

[0064] In the above structure, by setting a chamfer at the periphery of the end of the plug housing 11 that can be inserted into the adapter slot 21, the end of the limiting structure 22 that extends into the adapter slot 21 can bounce up along the chamfer during the process of inserting the plug 1 into the adapter slot 21, thereby avoiding the problem of plug jam; by setting a chamfer at the periphery of the slot of the adapter slot 21, it can be convenient to insert the plug 1 into the adapter slot 21; by setting a chamfer at the periphery of the slot of the board slot, it can be convenient to insert the gold finger board 12 into the board slot.

[0065] The implementation method of the specific embodiment of the present application is described in detail below:

[0066] Reference Figure 6 , when the plug 1 is pushed into the adapter slot 21 but has not yet contacted the limiting structure 22, one end of the limiting structure 22 extends into the adapter slot 21;

[0067] Reference Figure 7 and Figure 8 , push the plug 1 forward, when the plug 1 contacts the limiting structure 22, the end of the limiting structure 22 extending into the adapter slot 21 is lifted up by the chamfer of the edge of the end of the plug 1, so as not to block the plug 1 from going deeper; the limiting structures 22 located at the top, bottom, front and back push the plug 1 to the center of the adapter slot 21, ensuring that the plug 1 is aligned horizontally with the center of the socket 2;

[0068] Reference Fig. 9 , continue to push the plug 1 forward. When the gold finger board 12 contacts the assembly board 24, the gold finger board 12 can adaptively adjust the amplitude slightly and insert it into the board slot along the chamfered edge of the slot of the board slot; continue to push the plug 1 forward until the limit groove 111 is aligned with the limit structure 22, one end of the limit structure 22 extends into the adapter slot 21 and is inserted into the limit groove 111. At this time, the plug 1 and the socket 2 are plugged in place.

[0069] The second aspect of the utility model provides a processor, referring to Fig.10 The processor includes the signal switching structure described in any of the above embodiments, and therefore has the technical effects of any of the above embodiments, which will not be repeated here.

[0070] The third aspect of the utility model provides an endoscope system, which includes the signal switching structure described in any of the above embodiments or the processor described in the above embodiments. When the endoscope system visits the diseased area, since the endoscope system is provided with the signal switching structure described in any of the above embodiments, the wiring position is not easy to loosen, the stability of data transmission is high, and the data transmission problems that are easy to occur due to poor contact, such as no display after connection and partial function failure, are effectively improved, and the reliability of the endoscope connection is enhanced.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
