To keep the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known parts of the invention has been omitted.

As shown in fig. 1 to 7, an embodiment of the utility model discloses a data interface of industry touch screen, this data interface includes: frame 10, core skeleton 20 and binding post.

As shown in fig. 1 and 2, the frame is formed by bending a galvanized steel sheet, and the frame body 10 defines a rectangular socket into which a plug at the end of the data line is fittingly inserted. Feet are formed on the outer side of the frame and are used for being fixedly connected with a frame of the touch screen.

As shown in fig. 2 and 3, the core frame 20 is disposed in the frame, the core frame 20 includes a main body portion 22 located at the rear side of the frame and a tongue portion 21 extending into the middle of the frame, the tongue portion 21 has a flat and horizontal mounting surface 211, and the mounting surface 211 has a plurality of embedding grooves 212 arranged in parallel at intervals. The rear side of the main body 22 is formed with a vertical surface 221, the vertical surface 221 is perpendicular to the mounting surface 211, the vertical surface 221 is provided with a plurality of positioning grooves 222 which are arranged at intervals and in parallel, the plurality of positioning grooves 222 correspond to the plurality of embedding grooves 212 one by one, and the depth of the positioning grooves 222 is greater than that of the embedding grooves 212. A plurality of rectangular through holes are further formed in the junction area between the tongue portion 21 and the body portion 22, and the through holes correspond to the insertion grooves 212 and the positioning grooves 222 one to one.

The connection terminal comprises a plurality of contact pins 30, the contact pins 30 correspond to the embedding grooves 212 and the positioning grooves 222 one by one, as shown in fig. 7, the contact pins 30 are substantially L-shaped, that is, the contact pins 30 comprise vertical flat pins 31 and vertical pins 32 which are perpendicular to each other, the contact pins 30 are arranged according to the arrangement direction of the embedding grooves 212 and the positioning grooves 222, the flat pins 31 are located in the embedding grooves 212, correspondingly, the vertical pins 32 are located in the positioning grooves 222, and the flat pins 31 protrude out of the installation surface 211.

The utility model discloses in:

as shown in fig. 3 and 4, guide bars 2121 are formed on both groove walls at the front end of the fitting groove 212, guide grooves 311 are formed on both sides of the head portion of the flat leg 31, the guide grooves 311 extend forward to penetrate the head portion of the flat leg 31, and as shown in fig. 7, a stopper 3111 is formed at the rear end of the guide grooves 311.

The following describes the process of mounting the contact pin 30 to the core frame 20:

the head of the flat leg 31 of the contact 30 is pierced, and then the head of the contact 30 is slid from the rear side of the fitting groove 212 to the front side of the fitting groove 212, and the guide bar 2121 is slid into the guide groove 311 of the head of the flat leg 31, and the guide bar 2121 cooperates with the guide groove 311 to restrict the head of the flat leg 31 of the contact 30 from warping. Therefore, when the data interface is in the use condition of a plug needing frequent plugging of the data line of the board, the head of the flat pin 31 cannot warp due to frequent plugging, so that the plug can be plugged and unplugged smoothly, and the electric connection condition is better.

After the head of the flat pin 31 is slid to the front end of the embedding groove 212, the vertical pin 32 of the contact pin 30 enters the positioning groove 222 right, and the colloid is poured into the positioning groove 222 to fix the vertical pin 32 in the positioning groove 222, thereby preventing the flat pin 31 from moving integrally along the extending direction of the embedding groove 212.

In some preferred embodiments, as shown in fig. 5 to 7, the middle of the flat leg 31 is bent into an arch 312 by stamping, which makes the flat leg 31 form a structure with two low ends and a high middle, and after the plug is inserted into the data interface, the contact pin 30 of the plug contacts with the arch 312 area of the flat leg 31, which may facilitate better electrical connection between the plug and the data interface.

In some preferred embodiments, the thickness of the flat foot 31 at the arch 312 is made less than the thickness of the other areas of the flat foot 31. This makes it easier for the flat leg 31 to elastically deform at the arch 312 than at other areas, and thus the elastic deformation compensates for the assembly error of the contact leg 30 of the plug and the contact leg 30 of the data interface. Since the guide groove 311 of the flat leg 31 has the stopper 3111 at the rear end thereof, the rear end of the guide bar 2121 fitted in the groove 212 stops the stopper 3111 to restrict the movement of the head of the flat leg 31 due to the deformation of the arch 312, and further restrict the deformation of the arch 312.

As shown in fig. 7 and fig. 2, a triangular rib 313 is formed at the rear end of the flat leg 31, the flat leg 31 passes through the through hole and then extends into the embedded groove 212, the upper hole wall of the through hole is used for pressing against the triangular rib 313, and the pressing of the hole wall of the through hole against the triangular rib 313 causes the flat leg 31 to be tightly pressed against the embedded groove 212 with a certain pretightening force.
