Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 3, the pin socket suitable for bidirectional insertion of an external pin in the present embodiment includes a socket body 1, the socket body 1 has a plurality of pin insertion holes 3 with pins 2, wherein the pin insertion holes 3 are through holes penetrating through the socket body 1, the pins 2 are arranged on the socket body 1 in a queue, for example, the pins 2 may be arranged on the socket body in a manner similar to a centipede leg pattern as a whole; an electrical connection point for an external pin to be inserted into is formed on the pin 2 and at the position of the pin insertion hole 3 so as to realize electrical contact between the pin and the external pin; along the direction in which the pin insertion holes 3 penetrate the socket body 1, the electrical connection points are located in the corresponding pin insertion holes 3, and the electrical connection points are located at the middle positions of the pin insertion holes 3 in the penetrating depth direction. Wherein, one end of the pin 2 can be embedded in the corresponding pin inserting hole 3. Of course, the pins 2 are preferably arranged uniformly on the socket body 1 in a form of a queue and at equal intervals.

When the pin socket of the embodiment is matched and connected with an external part which is positioned on a PCB and is provided with an external pin, the external pin of the external part can be inserted into the pin inserting hole on one side of the socket body, so that the external pin and the pin 2 on the pin socket are electrically connected in the corresponding pin inserting hole; because the pin is located this contact pin patchhole intermediate position in the depth direction of penetration with the electrical connection point of external contact pin electrical contact, ensure that external contact pin can both electrically contact this pin socket's pin on this contact pin patchhole just, on the contrary any direction, so can realize that the contact pin of external part (external contact pin promptly) all can be through behind the contact pin patchhole 3 that corresponds above socket ontology or following two directions, realize with the electrical connection of pin socket upper lead pin.
