V. New description: [New technical field] This creation is about a connector, especially a connector that can hold the electrode of the lamp tube 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 does not have a light-emitting property in the liquid crystal display panel. 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. The function of the liquid crystal display panel is to provide a surface light source with 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. Due to the fragile structure of the lamp, it is easy to cause damage when a slight pressure is applied to the glass tube. Excessive pressure on the glass tube must be avoided when performing the assembly work. In addition, when performing maintenance on a liquid crystal display using a lamp, care must be taken to avoid damage. Therefore, it is generally necessary to fix the lamp tube to the backlight module by the aid of the connector. The conventional lamp connector is composed of an insulating body having an opening and a pair of flexible conductive elastic sheets disposed in the opening. Composed, and a metal casing is sleeved at both ends of the lamp tube, and then the metal 3 M362420 casing is pressed and inserted into the gap between the conductive elastic pieces, and the metal casing is held by the elastic restoring force of the conductive elastic piece, and Between one end of the metal casing and the electrode of the lamp tube, a welding joint is generally used to form a fixed joint between the metal casing and the lamp electrode to prevent the occurrence between the metal casing and the lamp electrode. Poor electrical contact. However, the structural disadvantage of such a connector is that it is necessary to put a metal casing on both ends of the lamp tube, and a welding joint is used to form a fixed joint between the metal casing and the electrode of the lamp tube, so that the manufacturing process not only makes the production time and The cost will increase and the production yield will decrease at the same time. [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. It is in a connected state, but this production process has problems of reduced production yield and increased production costs. The present invention provides a connector comprising an insulative housing and a conductive terminal, wherein the insulative housing has a receiving slot and a slot for connecting the receiving slot. The conductive terminal is mounted in the receiving groove of the insulative housing, wherein the conductive terminal has a body, two opposite front clamping arms, two opposite rear clamping arms and one pin, two front clamping arms are connected to the body, and two rear clamping arms are connected to the body. The arm is connected to the body, and the two front clamp arms and the two rear clamp arms are arranged in front and rear. The pins are connected to the body and are located below the two front clamp arms, 4 M362420 ί slot system:: the circuit board is plugged in two The clamping arm is used for clamping - the lamp is used to clamp and electrically connect the electrodes of the lamp tube. J provides the connector, which uses the design of the two ends of the conductive end and the two = arm, which can directly accommodate the end of the lamp;; = = the electrode of the lamp, so that the connector does not need to be rod-connected' A stable connection state can be achieved without setting a metal sleeve on both ends of the tube. ^

The slot can be extended to be adjacent to the slots 22, 23, and the receiving slot 20 is in communication with the slots 22, 23, and the insertion slots of the slots 5 M362420 22, 23 and the receiving slot 2 The insertion port is in the vertical direction. In this embodiment, the limiting member and the plate body 21 are used to stably set the insulating body 2 on the backing plate. In addition, a recess 203 is further provided at the opening of the valley groove 20 of the insulative housing 2, and the recess 2Q3 positions the position and direction of the bulb 4 to prevent the lamp tube 4 from being displaced left and right. The conductive terminal 3 is for holding a bulb 4 and is electrically connectable to the electrode 41 of the bulb 4. In this embodiment, the conductive terminal 3 includes a body 30, two opposite front clamping arms 31, two opposite rear clamping arms 32, and a plurality of upper pins 33 and lower pins 34, wherein the side of the body 30 The edge portion 301 is engaged with the groove 201 of the inner edge of the receiving groove 2 of the insulative housing 2 to fix and fix the conductive terminal 3 to the insulative housing 2. The two front clamping arms 31 are connected to the body 30 via a connecting portion 35 and are located on one side of the body 30, and an accommodating space 310 for accommodating the holding lamp tube 4 is formed between the two front clamping arms μ. In the embodiment, since the front clamp arm 31 may generate a burr at the cross section during the press forming process, in order to avoid the influence of the burr on the lamp tube 4, a plurality of convex portions are further disposed on the front clamp arm 31. The starting point 311 is to lift the lamp tube 4 slightly away from the punching section of the front clamping arm 31. In addition, the raised point 311 also has the function of holding the lamp tube 4. In this embodiment, since the two front clamp arms 31 are connected and are located on one side of the body 3, in order to make the one clamp arm 31 more stable when clamping and supporting the lamp tube 4, the two front clamp arms 31 are A support portion 36 is disposed under the support portion 36.

In the same way, when the metal contacts of the circuit board connected to the Tianyu contact the lower pin 34, the circuit board can also be in circuit communication with the conductive terminal 3 of the connector 1. The upper pin 33 and the lower (10) 34 material can make the circuit board at the same time without considering that the metal contact of the circuit itself is on the upper surface or the I: face can also achieve the electrical connection effect. In addition, the first leg 3/ stands under the first slot 22 to correspond to the arrangement of the contacts 33 in the lower basin, respectively. When the lower pin 33 or the upper contact 34 = one of them is unsuitable for unexplained reasons, the connection of the creation ^ has other spare electrical contact points available for use. Refer to the sixth to ninth drawings. 'This creation provides two = connector 5 for fixing - the lamp 4, which = = and the connector 5 is mounted on the back plate (two ° 5 has an insulative body 6 And a conductive terminal 7, wherein the insulating body 6 is white - ten electric (shown), - the limiting member (not two = slot 6 °, - board body (not marked electrical terminal 7 includes two meetings:) and slot (not Marked), the set of 'ί: the oppositely disposed two front cooling arms 71, the phase 74, the combination of the fixed pin 73 and the lower pin 5 of the present embodiment and the connector M3 62420 described above The combination of the components of FIG. 1 is substantially the same as the function, and therefore will not be described again. The difference is mainly that the two portions of the connector 5 of the connector 5 of the embodiment are overlapped to form an approximately circular shape. The closed hole 720 is configured to receive the electrode 41 of the holding lamp tube 4. The two front clamping arms 71 and the two rear clamping arms 32 are arranged in parallel in front and rear so as to be between the two front clamping arms 71. The central direction of the accommodating space 710 is approximately the same axial direction as the central direction of the closed hole 720. In the present embodiment, the two front arms 71 are The two rear clamping arms 72 and the body 70 are integrally formed elastic structures, so that the two rear clamping arms 72 can respectively be elastically deformed relative to the body 70, so that the distance between the two rear clamping arms 72 can be changed. When the electrode 41 of the lamp tube 4 is mounted on the conductive terminal 7, the two rear clamp arms 72 are slightly extended by fingers, so that the distance between the two rear clamp arms 72 is increased, so that the original closed hole 720 will be closed. After opening the opening, the lamp 4 and its electrode 41 are respectively placed in the accommodating space 710 between the two front arms 71 and the open opening between the two rear arms 72, and then the fingers are released. The clamping arm 72 causes the distance between the two rear clamping arms 72 to return to the original state by the elastic restoring force. Since the diameter of the electrode 41 is slightly larger than the diameter of the closed hole 720, the two rear clamping arms 72 are just right. The electrode 4 of the lamp tube 4 is clamped and electrically connected to the closed hole 720. In summary, the connector of the present invention is provided with a fixed holding lamp tube on the conductive terminal of the connector and The front and rear arms of the electrode To stabilize the holding of the lamp, so that the lamp is not 9 M362420, and then the metal casing and the welded connector are stably connected to each other to achieve a reduction in the production rate during the manufacturing process. In addition, the connector of the present invention has two slots of the second conductive pin with an increase in production cost, so that when the electric pin and the problem of poor electrical rhyme occur, the electric connection is made.
