New description: [New technical field] This creation is about a connector', especially for a connector that can hold the electrode of the lamp without soldering. [Prior Art] Liquid crystal display panels have been widely used in various information, communication, and consumer products. However, since the liquid crystal itself in the liquid crystal display panel does not have an illuminating property. Therefore, in order to achieve the display effect, it is necessary to provide a light source device to the liquid crystal display panel. In the prior art, a liquid crystal display panel having a backlight module is well known, and its function is to provide a surface light source having a sufficient brightness and uniform distribution to the liquid crystal display panel. Generally, the backlight module is designed to be provided with a plurality of lamps spaced apart from one side of the back plate. The two ends of the lamp are respectively fixed on a connector, and the connector is disposed on the back plate. Since the structure of the lamp tube is relatively fragile, the lamp tube generally needs to be assembled and fixed on the backlight module by the aid of the connector. The conventional lamp connector is composed of an insulating body having an opening and one of the openings. The flexible conductive elastic piece is composed of a metal sleeve disposed at both ends of the lamp tube, and then the metal shell sleeve is squeezed and inserted into the gap between the conductive elastic sheets to be held by the elastic restoring force of the conductive elastic piece Metal case, M369558 ^^ j between the end of the metal casing and the electrode of the lamp, the welding joint is also used to form a fixed joint between the metal casing and the lamp 16 to prevent metal Poor electrical contact between the sheath and the tube electrode. However, the structural disadvantage of such a connector is that it is necessary to put a metal sheath on both ends of the lamp s and the welding method is to form a fixed joint between the metal shell-f and the electrode of the lamp, so that the process not only enables The time and cost of paying for production will increase, and the production yield will also decrease. [New content] Conventional connectors need to form a fixed joint between the metal casing and the lamp electrode before inserting the metal casing into the gap between the conductive elastic pieces of the connector so that the lamp and the connector are connected. In a connected state, but this production process has the problem of reduced production yield and increased production cost of B. The present invention provides a connector for supplying power from a power source disposed on a front side of a backplane to a power source disposed on a back side of the backplane, wherein the connector includes an insulative housing, a conductive terminal, and an upper cover, and is insulated The body has a receiving groove. The conductive terminal is mounted in the receiving groove of the insulative housing, wherein the conductive terminal has a first clamping arm and a second clamping arm. The upper cover is mounted on the insulative housing, wherein the upper cover is provided with an interference M369558' that can push and push the clamp arms. The present invention provides another connector for supplying power from a power source disposed on a front side of a bottom plate, and supplying power from a power source disposed on a back side of the bottom plate, wherein the connector includes an insulating body, a conductive terminal, and an upper cover. The insulating body has a receiving groove. The conductive terminal is mounted in the receiving groove of the insulating body, wherein the conductive terminal has a first clamping arm and a second clamping arm, and the illuminating arm forms a hole for holding the electrode of the lamp tube. The upper cover is movably assembled on the insulative housing, wherein the upper cover is provided to be capable of pushing the interference portion of the clamping arm, and when the upper cover is moved to the open position for assembling the electrode of the lamp tube, the interference portion interferes with the The clamping arms are configured to open the holes between the clamping arms, and when the upper cover is moved to the closed position where the electrodes of the lamps are not assembled, the interference portions do not interfere with the clamping arms to make the clamping arms The hole is closed. The connector provided by the present invention utilizes a design of interference between the two clamping arms of the conductive terminal and the upper cover, so that the upper cover interferes against the two clamping arms so that the two clamping arms are apart from each other to form a The opening state of the insertion of the lamp electrode is performed, and then the upper cover is not subjected to the '^ interference top to the two clamp arms, so that the two clamp arms return to the closed state of the original mutual sin. The hole between the two clamp arms is The electrode of the fixed lamp tube can be accommodated and held, so that the connecting material needs to pass through the welding process and the metal casing is not disposed at both ends of the lamp tube to achieve a stable connection state. 5
