Plug-securing connecting apparatus and socket
View Patent ↗An electrical socket with a security fixing includes a base and a number of terminal portions. The base includes an inserting side. The inserting side defines a number of receiving grooves. The terminal portions are fixed in the receiving grooves to conduct electricity to a plug. Two clamping members are protruded from the inserting side and when the plug is inserted into the terminal portion, the two clamping members latch onto the plug to hold it in place.
1. A socket comprising:
a base comprising an inserting side, the inserting side defining a plurality of receiving grooves;
a plurality of terminal portions in the receiving grooves, each terminal portion configured to electrically connect to a plug;
a plurality of pairs of clamping members protruded from the inserting side, when a plug inserts into the terminal portion, one pair of the clamping members clamp the plug;
wherein the clamping member comprises a clamping portion and a contacting portion, the clamping portion extends away from the inserting side, and the clamping portion is substantially a trapezoid, the contacting portion extends away from the clamping portion, and is perpendicular to the inserting side, the clamping portion comprises a sliding surface and a restricting surface, the sliding surface obliquely connects to the contacting portion, the restricting surface connects the sliding surface to the contacting portion, an angle between the restricting surface and the sliding surface is an acute angle.
2. The socket of claim 1 , wherein the restricting surface is parallel to the inserting surface, a clamping groove is formed between the restricting surface and the inserting surface.
3. The socket of claim 1 , wherein the socket comprises four terminal portions, the base defines four receiving grooves.
4. A socket comprising:
a base defining a plurality of receiving grooves;
a plurality of terminal portions in the receiving grooves, the terminal portion configured to electrically connect to a plug;
two clamping members protruded from two opposite edges of the base surrounding each receiving groove, when the plug inserts into the terminal portion, two clamping members clamp the plug;
wherein the clamping member comprises a clamping portion and a contacting portion, the clamping portion extends away from the inserting side, and the clamping portion is substantially a trapezoid, the contacting portion extends away from the clamping portion, and is perpendicular to the inserting side, the clamping portion comprises a sliding surface and a restricting surface, the sliding surface obliquely connects to the contacting portion, the restricting surface connects the sliding surface to the contacting portion, an angle between the restricting surface and the sliding surface is an acute angle.
5. The socket of claim 4 , wherein the restricting surface is parallel to the inserting surface, a clamping groove is formed between the restricting surface and the inserting surface.
6. The socket of claim 5 , wherein the socket comprises four terminal portions, the base defines four receiving grooves.
7. A connecting apparatus comprising:
a socket comprising:
a base defining a plurality of receiving grooves;
a plurality of terminal portions fixed in the receiving grooves;
two clamping members protruded from an inserting side of the base adjacent to each receiving groove;
a plurality of plugs, each plus comprising:
a cable; and
a main body connected to one end of the cable, the main body partly received in one of the receiving groove and inserted into the terminal portion to electrically connect to the terminal portion, and clamped is fixed between two clamping members;
wherein the main body comprises a fixing portion and a connecting portion, the connecting portion extends from an end of the fixing portion away from the cable, an extending direction of the connecting portion is same as an inserting direction of the plug inserting to the socket, an area of a cross section of the connecting portion perpendicular to the extending direction has an area is larger than an area of a cross section of the fixing portion perpendicular to the extending direction, the clamping member comprises a clamping portion and a contacting portion, the clamping portion extends away from the inserting side, and the clamping portion is substantially a trapezoid, the contacting portion extends away from the clamping portion, and is perpendicular to the inserting side, the clamping portion comprises a sliding surface and a restricting surface, the sliding surface obliquely connects to the contacting portion, the restricting surface connects the sliding surface to the contacting portion, an angle between the restricting surface and the sliding surface is an acute angle.
8. The connecting apparatus of claim 7 , wherein the restricting surface is parallel to the inserting surface, a clamping groove is formed between the restricting surface and the inserting surface.
9. The connecting apparatus of claim 7 , wherein the socket comprises four terminal portions, the base defines four receiving grooves.
