The invention relates to a receptacle connector, and more particularly to a receptacle connector with a cable-clamped structure.
The network module socket is usually used to connect various network cables in the network computer room, including single wire, multiple wires, and wires of various diameters. The network module socket in the prior art is provided with an electrical module in a housing, and the contact terminal of the electrical module extends to a receiving opening close to the housing. The contact terminals are in contact with the terminal of the plug connector when the mating plug connector is inserted into the housing. The rear end of the housing is provided with a prick type terminal slot, the prick type terminal of the electrical module is set in the prick type terminal slot, and the multiple core wires of the cable are set in the multiple fixing slots of a wire securing structure. A cover pivoted to the rear end of the housing is pressed the housing so that the wire securing structure is crimped to the prick type terminal groove at the rear end of the housing, so that the prick type terminal of the electrical module is pierced through the core wire to achieve electrical connection.
U.S. Pat. No. 7,713,081 discloses a structure similar to the aforementioned structure. However, U.S. Pat. No. 7,713,081 has two covers connected to a front case of the housing, and the rear case is exposed for a cable being inserted thereinto when the covers are opened. The wires of the cable are connected to the prick type terminals. When the covers are in a closed position, the rear case is covered and a clamping section is formed. A cable pressing block is mounted to a rear end of one of the covers and regularly extends to the clamping section. When the covers are in the closed position, the cable pressing block contacts the network cable and push the cable to abut the other cover.
U.S. Pat. No. 7,371,106 discloses a cover with two grooves on opposite sides. Several engaging structures are disposed on the other side of the grooves. When the connector is mounted to a network module, an M-shaped metal sheet is inserted into the groove to form a hook structure engaging the engaging structure.
The aforementioned receptacles have engaging structures for network cable of different diameters. U.S. Pat. No. 7,713,081 utilizes the spring structure, but the spring is compressible so that the cable pressing block may have no contact with the network cable when the network cable is offset. As for U.S. Pat. No. 7,371,106, although the condition of no contact never happens, the parts of the connector are increased.
An object of the invention is to provide a receptacle connector with cable clamping structure including a pair of clamping members, and one of the clamping member is provided with a cable clamper capable of adjusting clamping position according to a diameter of the cable. The cable clamper is positioned by a positioning structure after the cable clamper has clamped the cable, whereby the cable is clamped between the clamping members. Therefore, even if the network cable is offset, the cable clamper still clamps the cable.
The invention provides a receptacle connector with a cable-clamped structure. The receptacle connector with a wire clamped structure in accordance with an exemplary embodiment of the invention includes a housing including a front case and a rear case, wherein the front case has a receiving opening through which a plug connector is inserted and an accommodating space, and the rear case has a plurality of prick type terminal slots; an electrical module disposed in the housing and including a circuit board disposed between the front case and the rear case, a plurality of contacting terminals disposed on the printed circuit board and a plurality of prick type terminals disposed on the printed circuit board, wherein the contacting terminals are disposed near the receiving opening for contacting terminals of the plug connector, and the prick type terminals are disposed in the prick type terminal slots and connected to a wire of a cable; and a cable clamping module including a first clamping member, a second clamping member and a cable clamper, wherein the first clamping member engages the second clamping member, and the cable clamper is pivoted to the first clamping member; wherein the cable clamper includes a pressing portion and a first positioning portion, the first clamping member includes a second positioning portion, a cable extends through the first clamping member and the second clamping member engaging the first clamping member, the pressing portion presses the cable with the first positioning portion positioned in the second positioning portion of the first clamping portion.
The receptacle connector with a cable-clamped structure of the invention includes a cable clamper disposed in the first clamping member, and the position of the cable clamper is adjusted according to the diameter of the cable, and afterwards the cable clamper is positioned in the first clamping member. Therefore, even if the network cable is offset, the cable clamper still clamps the cable.
