[0025] The utility model provides a waterproof connector and a B-ultrasound device based on a B-ultrasound probe. In order to make the purpose, technical solution and advantages of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] See also Figure 1 , Figure 2 and Figure 3The B-ultrasound device provided by the utility model includes a shell 1, a waterproof silicone sheet 2, a waterproof gasket cover 3, a B-ultrasound probe and a waterproof connector based on the B-ultrasound probe. The shell is provided with an existing mainboard 4, and an interface hole is opened on one side of the shell 1. The female seat 5 of the waterproof connector is arranged on the inner side of the shell and inserted into the interface hole. The female seat 5 is tightly attached to the interface hole through the waterproof silicone sheet 2; the male seat 6 of the waterproof connector is arranged at the interface of the B-ultrasound probe, and the male seat 6 is inserted into the female seat 5 and self-locked. The male seat 6 is tightly attached to the interface hole through the waterproof gasket cover 3. The female seat 5 of the waterproof connector is connected to the mainboard, and the male seat 6 is connected to the probe cable of the B-ultrasound probe.

[0027] In this embodiment, the female seat 5 on the inner side of the shell realizes the internal waterproof function through the blocking of the waterproof silicone sheet 2; at the same time, the male seat 6 on the outer side of the shell realizes the external waterproof function through the isolation of the waterproof pad cover 3, and the male seat 6 will self-lock when inserted into the female seat 5. The combination of the three enhances the waterproof effect.

[0028] The waterproof pad cover 3 includes a cover 31 and a waterproof pad 32, and the cover 31 and the waterproof pad 32 are connected by a connecting belt 33; the waterproof pad 32 is screwed and fixed to the outside of the shell, and the male seat is inserted into the female seat from the opening in the middle of the waterproof pad 32. When the B-ultrasound device is not connected to the B-ultrasound probe, the cover 31 covers the opening of the waterproof pad 32 to protect the pins of the docking plug on the female seat from dust, deformation and waterproof; when the B-ultrasound probe is connected, the cover can be pulled out. The cover 31, the cover pad 32 and the connecting belt 33 are integrally formed, and the material is preferably silicone.

[0029] Please also read Figure 3 and Figure 4 The waterproof connector based on the B-ultrasound probe includes a female socket 5 and a male socket 6; the socket end 51 of the female socket 5 passes through the socket hole 21 of the waterproof silicone sheet 2 and the interface hole on the shell in turn, and extends from the outside of the interface hole; the plug end 61 of the male socket 6 passes through the opening on the waterproof pad 32 and is inserted into the socket end 51 of the female socket 5, and the clamping component on the plug end self-locks the male socket and the female socket.

[0030] Among them, the snap-on assembly includes grooves arranged on the left outer side and the right outer side of the plug end 61, and a press-type self-locking piece 62 arranged in the groove; the left inner side and the right inner side of the socket end 51 are respectively provided with a card slot for clamping the self-locking piece 62.

[0031] During insertion, the inclined surface of the self-locking member 62 is squeezed by force, so that the protrusion of the self-locking member 62 is pressed into the groove. As the plug end 61 continues to be inserted, until the protrusion of the self-locking member 62 enters the slot, the self-locking member 62 as a whole is no longer squeezed, and the elastic protrusion pops out of the groove and gets stuck in the slot, thereby realizing the insertion self-locking function.

[0032] When the probe is pulled out, the arc surface of the protrusion is squeezed by force, and the protrusion is pressed into the groove of the plug end 61. As the plug end 61 is continuously pulled out, until the self-locking member 62 is exposed as a whole and is no longer squeezed, the elastic protrusion pops out of the groove and returns to its original state, thereby facilitating the removal of the probe. The elasticity of the self-locking member 62 is used to achieve quick insertion and removal. The arc surface of the protrusion matches the slot in the female seat, which can ensure that the female seat and the male seat have a certain self-locking force, and can also make the male seat effortless to remove.

[0033] A fixing hole 53 is provided on the left and right sides of the main body top surface 52 of the female seat 5, and a copper nut is embedded in the fixing hole 53. The left and right ends of the waterproof silicone sheet 2 are provided with a first screw hole 22 adapted to the fixing hole (that is, the positions are relatively aligned so that the two holes have the same size), and the shell on both sides of the interface hole is provided with a second screw hole adapted to the first screw hole 22. During installation, the waterproof silicone sheet 2 is clamped between the female seat 5 and the inner side of the shell, and a screw is screwed into the fixing hole 53. The screw passes through the second screw hole and the first screw hole 22 from the outside of the shell and is screwed into the copper nut in the fixing hole 53 on the female seat, so that the waterproof silicone sheet 2 can be fastened between the female seat 5 and the shell. The size of the waterproof silicone sheet 2 is the same as that of the main body top surface 52.

[0034] The left and right sides of the main end surface 54 of the female seat 5 are respectively provided with a mounting hole 55, and the main board 4 is provided with a plate hole adapted to the mounting hole 55. The mounting hole 55 is aligned with the plate hole and screws are screwed in to fix the female seat 5 on the main board.

[0035] The pin end of the female base 5 includes a plurality of socket pins 56 bent at 90 degrees and a pin fixing plate 57. After extending from the female base 5, each socket pin 56 is bent at 90 degrees to form a right angle, and then passes through the corresponding pin fixing holes on the pin fixing plate 57, and is welded to the socket welding hole of the main board after extending from the pin fixing plate 57. Since each socket pin is relatively thin, the pin fixing plate 57 can prevent the problem of tilting, displacement, and deformation of each socket pin during movement, and can also play a role in fixing the position of the socket pin during welding. Setting the socket pin 56 at a right angle can facilitate welding with the main board.

[0036] In this embodiment, three socket pins 56 are provided, and correspondingly, three socket welding holes are provided on the mainboard. The hole layout is as follows: Figure 5As shown. Several socket pins 56 of the female socket 5 are inserted into the corresponding socket welding holes, and each socket welding hole is arranged in three rows in a staggered manner. The first row and the third row are respectively provided with 10 equally spaced socket welding holes in the horizontal direction, and the two socket welding holes aligned vertically in the first row and the third row are aligned; the second row is provided with 1 equally spaced socket welding hole, and the socket welding holes in the second row are staggered with the socket welding holes in the first row. The hole center spacing between the first row and the second row (the straight-line distance between the centers of the two socket welding holes) is equal to the hole center spacing L1 between the second row and the third row, preferably 1.27mm. The hole center spacing L2 between the first row and the third row is preferably 2.54mm. The hole row length of the second row (the hole center spacing between the two socket welding holes on the edge) L3 is preferably 14.5mm. Such a staggered arrangement is conducive to PCB wiring and facilitates the routing of each pin signal or power line.

[0037] Please also read Figure 6 The pin end of the male socket 6 includes a plurality of plug pins 63 and a wiring board 64. Each plug pin 63 extends from a corresponding plug hole on the wiring board 64 and is welded to the wiring board 64. The signal name of each plug hole is printed on the wiring board 64 ( Figure 6 The silk-screen printing method shown is only an example, and can be modified according to needs during specific implementation) to facilitate users to understand the types of various signals transmitted by the waterproof connector. One side of the wiring board 64 is arc-shaped, and a square brass-covered ground pin 67 is provided on one side. Three first through holes 68 are provided on the ground pin 67. The other side of the wiring board 64 is straight, which is conducive to the grounding of the shielding layer of each core wire. The front and back sides of the other side of the wiring board 64 are provided with a brass-covered grounding area 65 and a signal line area 66; a second through hole 69 is provided at both ends of the grounding area 65, and the first through hole 68 and the second through hole 69 are used for the shielding grounding of the probe cable, which is also conducive to the fixation of the entire probe cable. The signal line area 66 is used to weld (using semi-automatic laser welding) the various signal lines 70 of the B-ultrasound probe. These signal lines are electrically connected to the corresponding plug pins 63 through the wiring on the wiring board 64 to realize the data transmission of each signal. By setting the wiring board 64, the welding of the coaxial shielded core wire of the probe and the fixation and outlet of the entire probe cable are convenient.

[0038] Based on the different definitions of the plug pins 63 and the different signals transmitted, two first ribs 7 are provided on one end face of the plug end 61 of the male socket, and a second rib 8 is provided in the middle of the other end face; two first rib grooves for snapping into the first ribs 7 are provided on one end face of the socket end 51 of the female socket, and a second rib groove for snapping into the second rib is provided in the middle of the other end face of the socket end 51. In this way, the male socket on the B-ultrasound probe can be prevented from being inserted into the female socket in reverse, ensuring the correctness of signal transmission.

[0039] The upper part of the plug end 61 of the male socket is provided with a first annular ring 9 and a second annular ring 10, and a groove ring 11 is provided between the first annular ring 9 and the second annular ring 10. After the male socket is inserted, the top surface of the first annular ring 9 fits tightly with the waterproof pad on the outer side of the shell to play a waterproof role. The protrusion of the second annular ring 10 is conducive to the more firm rubber coating of the male socket terminal board and the pins.

[0040] In the prior art, the interface of the probe cable is similar to a USB interface, which is a straight plug-in male socket 6. Based on the above waterproof connector, in this embodiment, Figure 6 and Figure 7 ( Figure 7 The shell outline of the B-ultrasound device shown is only an example and is not limited here. As shown in the figure, the interface shell of the B-ultrasound probe is a right-angle type. The signal lines inside the interface are horizontally welded to the signal line area 66 on the front and back sides of the wiring board 64. Since the plug pins 63 are vertically welded to the corresponding plug holes on the wiring board 64, it is equivalent to the signal line being led out 90 degrees laterally through the wiring board and the plug pins, so that the outlet of the probe cable is 90 degrees to the interface direction of the B-ultrasound device. During use, the force generated by the probe cable being accidentally touched is along the direction of the probe cable ( Figure 7 The double arrows in the example are up and down), and the plugging and unplugging between the male and female sockets is along the direction of the socket ( Figure 7 The double arrow in the example indicates left and right directions). In this way, even if the probe cable is pulled by mistake, it can be prevented from being pulled off due to the different force directions between it and the socket. Only by holding the male socket can it be properly unplugged.

[0041] In order to further enhance the waterproof effect, after the probe cable is welded, the groove ring 11 of the male seat, the second annular ring 10 and the shell of the B-ultrasound probe can be encapsulated with rubber (the encapsulated area is as follows Figure 7 The rubber coating prevents water from entering the interface and makes the right-angle interface housing connection more secure; the arc shape on one side of the terminal block 64 is conducive to rubber coating, and the entire interface will be more compact and beautiful after rubber coating. When rubber coating, an elliptical concave surface 12 can be set on the front and back rubber surfaces of the rubber coating area respectively. When plugging and unplugging, the fingers pinch the concave surface 12, which is conducive to a more stable grip when plugging and unplugging.

[0042] To sum up, the waterproof connector and B-ultrasound equipment based on the B-ultrasound probe of the utility model have a compact waterproof connector structure, and are equipped with a waterproof silicone sheet and a waterproof gasket to improve the waterproof performance. The female and male sockets can be quickly plugged in and out, the welding is reliable, and the structure is compact. The performance requirements of the B-ultrasound probe for the connector are met, and the production efficiency and stability of the ultrasound probe are improved.

[0043] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, improvements or changes can be made according to the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
