Detailed Description

The technical scheme protected by the utility model is specifically described below with reference to the accompanying drawings.

As shown in fig. 1 and 2, a flat connector includes: the plastic body 2 is integrally injection molded, the terminals 3 are embedded in the plastic body 2, the terminals 3 are multiple, the terminals 3 are parallel and protrude out of the upper surface of the plastic body 2, and therefore the upper surface of the plastic body 2 forms a structure of multiple plastic bodies 2-terminals 3-plastic bodies 2.

As shown in fig. 5 and 6, the terminal 3 includes: the plastic body 2 comprises an end face 31 arranged on the upper surface of the plastic body 2, first bending parts 32 which are arranged at two ends of the end face 31 and are obliquely arranged at the edge of the plastic body 2, pins 34 arranged on the lower surface of the plastic body 2, and second bending parts 33 which are connected with the first bending parts 32 and the pins 34. The end face 31, the first bending portion 32 and the pins 34 are exposed outside the molding body 2, and the second bending portion 32 is embedded into the molding body 2.

When the external mating connector is inserted in the front of the use scene, the external mating connector is directly contacted and matched with the end face 31; when the external mating connector is inserted obliquely in a use scene, the external mating connector is contacted with the first bending part 32 at first, and the first bending part 32 is designed into a bending structure, so that the external mating connector can be guided, the external mating connector is convenient to contact with the first bending part 32 and rotate again before contacting with the end face 31, and finally contacts with the end face 31, and the external mating connector is always connected with the terminal 3. The two application scenes of front matching and rotary matching are realized, and the application range is wide.

Further, as shown in fig. 4, the end face 31 is slightly protruded from the upper surface of the molding body 2. The connector and the external mating connector are convenient to mate without interference.

Further, as shown in fig. 5, the pins 34 are protruded from the lower surface of the molding body 2, so as to facilitate the design of the subsequent process. In the present application, in order to make the product width as small as possible, but the product itself has a limited height, the terminal 3 is designed to be bent at a large angle to meet the requirements, that is, the second bending portion 33 in fig. 5 and 6 is designed to have a large bending angle, and plays a role of connecting the first bending portion 32 and the pin 34.

As shown in fig. 5 and 6, the second bending portion 33 is provided with a positioning groove 35, and a part of the molding body 2 is filled into the positioning groove 35 during injection molding, so that the connection stability of the terminal 3 and the molding body 2 is improved.

As shown in fig. 7, a hollow groove 22 is formed in the back surface of the plastic body 2, and the terminal 3 is exposed from the hollow groove 22. The plastic body 2 is convenient for fixing the terminal 3 in the molding process. The molding stability of the plastic body 2 is improved.

The pick-and-place device 1 comprises: the connecting plate 11 is symmetrically arranged on the clamping plates 12 at two sides of the connecting plate 11, and the distance D1 between the inner side walls of the clamping plates 12 at two sides is slightly smaller than the distance D2 between the two side walls of the plastic body 2. So that when the picking and placing device 1 clamps the plastic body 2, the holding force between the picking and placing device 1 and the plastic body 2 can be ensured due to the elasticity between the clamping plate 12 and the connecting plate 11, thereby facilitating the clamping of the whole connector.

Further, as shown in fig. 2, a limiting block 13 is disposed on the inner side of the plate 12, and a corresponding limiting groove 21 is formed on the outer side wall of the corresponding plastic body 2. The movement of the pick-and-place device can be restricted.
