The data interface plug 6 comprises a plug main body 61, a pin bank 62 protruding out of the plug main body, and two anti-drop pins 63 protruding out of the plug main body; the two anti-drop pins are positioned at two sides of the pin header, and the outer wall of each anti-drop pin is provided with an annular anti-drop groove 64.

The data interface socket comprises a socket main body 31, array holes arranged on the socket main body and connected with the pin header in an inserting mode, two mounting holes 33 arranged on the socket main body, anti-falling hole seats 34 arranged in the mounting holes and connected with corresponding anti-falling contact pins in an inserting mode, expansion rods 35 arranged in the mounting holes and used for expanding the aperture of corresponding anti-falling hole seats, prying rods 36 arranged on the socket main body in a rotating mode and used for prying corresponding expansion rods to move, and reset springs 37 used for providing reset elastic force for corresponding expansion rods.

Anticreep hole seat includes that to inlay the annular fixed part 341 of putting in the mounting hole through the injection moulding mode, all has anticreep pillar 343 of anticreep latch 342 with four of annular fixed part integrated into one piece, these four anticreep pillars enclose close form one with the jack of anticreep contact pin adaptation, and each anticreep pillar leaves the clearance each other, also leaves the clearance between the inner wall of the periphery wall of these four anticreep pillars and mounting hole, this kind of structure can make these four anticreep pillars can take place elastic deformation. When the anti-drop contact pin is inserted into a corresponding anti-drop hole seat, the anti-drop latch is clamped into the anti-drop groove on the outer wall of the anti-drop contact pin; the anti-falling latch in the embodiment preferably adopts anti-falling inverted teeth, so that sufficient anti-falling force can be ensured between the anti-falling inverted teeth and the anti-falling latch, and the connection stability is ensured.

Each anti-drop pillar is also provided with an expansion inclined wall 344 at one end close to the annular fixed seat, the expansion inclined wall is positioned between the anti-drop latch and the annular fixed part, the expansion inclined walls of the four anti-drop pillars surround to form a conical hole-shaped jack, and the aperture of the jack is gradually reduced along the direction close to the annular fixed seat.

The expanding rod comprises a cone frustum-shaped expanding head 351 and a pull rod 352; the expansion head and the pull rod are both positioned in the insertion hole of the corresponding anti-drop hole seat, and the tail end 353 of the pull rod penetrates through the central hole of the annular fixed seat and then extends out of the mounting hole; the outer diameter of the expansion head is gradually reduced along the direction close to the annular fixing part, namely the shape of the peripheral wall of the expansion head is closely matched with the jack of a corresponding anti-drop hole seat; in this embodiment, the expansion head is located in the receptacle.

The return spring is positioned in the jack, the return spring is sleeved on the pull rod, one end of the return spring is abutted against the annular fixed seat, and the other end of the return spring is abutted against the expansion head; when the expansion head moves along the direction close to the annular fixed seat, the return spring provides the elastic force for returning to the original position.

The shape of pinch bar is the V-arrangement, its one end links to each other with the pull rod of a corresponding expansion lever, its V-arrangement center contained angle department rotates through the pivot and sets up in socket ontology, its other end is located one side of socket ontology, when pulling the pinch bar and making it revolute the rotation of axes, can drive a corresponding expansion head and make its remove along the direction that is close annular fixing base, the expansion head that links to each other with this pull rod can expand corresponding four anticreep pillars, thereby enlarge the jack aperture, can extract the anticreep contact pin from the anticreep hole seat smoothly this moment.

When this embodiment uses, directly insert data interface plug 6 in data interface socket 3 for the row needle inserts battle structure hole, and the anticreep contact pin inserts the anticreep hole seat, can accomplish the data connection of color Doppler ultrasound probe and signal processing main part, and at this moment under the effect in anticreep latch chucking anticreep groove, both are difficult to directly extract.

When the color ultrasonic probe needs to be replaced or maintained, the two prying bars can be held inwards to drive the two expansion heads to move towards the direction close to the annular fixed seat, the expansion heads extrude the inclined wall and prop open the four anti-falling pillars, so that the aperture of the anti-falling hole seat is enlarged, the anti-falling clamping teeth can be separated from the anti-falling groove, and the anti-falling contact pins can be easily pulled out of the anti-falling hole seat; after the operation is finished, when the two pry bars are not held, the return spring pushes the pull rod to return to the original position, and meanwhile, the pry bars are driven to return to the original position.
