[0009] The European-style socket is characterized in that a bushing corresponding to the plug-in port is provided on the terminal seat.

[0010] The socket female terminal and European socket of the utility model have the following advantages: 1. The sheet structure is simpler, easy to produce and low in cost; 2. Four triangular elastic contacts arranged in a circle are used to form the plug interface, which can better clamp the cylindrical male terminal, and has better stability and fatigue resistance; 3. The sheet body is riveted to the slot of the terminal seat by means of a retaining tooth, and the connection is more stable and not easy to fall off.

[0011] The utility model is further described below in conjunction with the accompanying drawings of the specification. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Reference Figure 1-3 As shown, the female terminal for the socket of the utility model comprises a rectangular sheet-like body 1, one end of which is provided with an insertion port 2, and the other end of which is provided with a screw hole 3. The screw hole 3 may be threadless or with internal threads. The insertion port 2 is surrounded by four triangular elastic contact pieces 4 arranged in a circle and integrally formed, and the upper diameter R1 of the insertion port 2 is larger than the lower diameter R2. The surface of the triangular elastic contact piece 4 is a concave surface 5 that smoothly transitions with the sheet-like body 1, and the concave surface 5 allows the cylindrical male terminal to be better inserted and better wrapped in the male terminal, so as to increase the contact area and thus improve the interception capacity.

[0019] Preferably, two sides of the sheet-like body 1 are provided with stop teeth 6. The stop teeth 6 are riveted to the slots to improve the stability of the installation.

[0020] Preferably, a screw 7 is provided in the screw hole 3 of the sheet-like body 1. When the screw hole 3 is unthreaded, the screw 7 needs to be equipped with a nut to facilitate wiring. Embodiment 2:
