The invention discloses an electrical connector. The first conductive part of the electrical connector abuts against the lower surface of the first grounding contact part on the docking part and is integrally connected with the first conductive part by providing a first conductive part on the conductive plastic. The second conductive part is in contact with the upper surface of the first extension part located behind the docking part, so that the conductive plastic can be in contact with the front section and the rear section of the first ground terminal at the same time to form a multi-point contact, which not only ensures that the conductive plastic is in contact with the ground The good conduction effect between the terminals further improves the grounding effect of the grounding terminal. In addition, since the first conducting part and the second conducting part are respectively located on the upper and lower surfaces of the first grounding terminal, the conductive plastic and the first grounding terminal The upper contact is more stable, ensuring the high-frequency transmission quality of the electrical connector.

The sensing device includes following parts: a hollow seat; two terminal units with opposite first side face and second side face installed and positioned inside the hollow seat; current conducting ball located in a accommodation hole in the seat and position-limited by the terminal units. Each terminal unit includes separated a first terminal and a second terminal. Each first terminal and second terminal possesses a main body portion, a terminal portion extended from the main body portion along upright direction, and an extension portion extended from inner side face of the main body portion along horizontal direction. When the sensing device is installed on a circuit base plate vertically, the ball contacts second terminals only so that the sensing device is in off state. When the sensing device is tilted, the ball contacts first terminals and second terminals as well so that the sensing device is in on state. The invention possesses good sensing effect.

The invention belongs to the field of preparation of conductive composites and in particular relates to a preparation method and application of a one-dimensional rod-spherical attapulgite / polyaniline conductive composite. Attapulgite rod crystals are taken as a carrier, firstly, iron oxide nanoparticles are loaded on the surfaces of the attapulgite rod crystals, and then released Fe<3+> is utilized for oxidizing a phenylamine monomer on the surface of iron oxide in an iron oxide self-dissolution process, so that the rod-spherical attapulgite / polyaniline conductive composite is formed. The conductive composite can be applied to paint.
