Description

Connection structure between lamp tube and lamp holder

technical field

The utility model relates to a connection structure between a lamp tube and a lamp holder, in particular to a connection structure between an LED lamp tube and a lamp holder.

Background technique

In the prior art, the connection method between the two ends of the long lamp tube and the lamp holder is generally as follows: first, align the conductive pins at both ends of the lamp tube and insert them into the corresponding jacks on the connecting end of the lamp holder, and then rotate the lamp tube back and forth to find the correct position. anchor point to complete the installation. Since the distance between the connecting ends of the two lamp holders is equivalent to the length of the lamp tube, during installation, after inserting the conductive pin at one end of the lamp tube into the socket at the connecting end of the lamp holder at that end, you need to use one hand to hold the other end. The connecting end of the lamp holder is bent radially outward, so that the conductive pin at the other end can be inserted into the socket of the connecting end of the lamp holder, which is difficult to operate. Especially when replacing the lamp tube, because the lamp body is generally installed on a high place such as a roof, the installer needs to work on a high place, and the installation between the above-mentioned lamp tube and the lamp holder is particularly difficult.

Contents of the invention

The purpose of the utility model is to provide a connection structure between a lamp tube and a lamp holder, which has a simple structure and makes the installation of the lamp tube and the lamp holder convenient and reliable.

The technical scheme of the utility model is: a connection structure between a lamp tube and a lamp holder, comprising a lamp tube with conductive needles at both ends and a lamp holder with connecting ends at both ends, and the conductive needles at both ends are respectively installed on the connecting ends at both ends, The connecting end includes a connecting seat fixed to the lamp holder and a buckle installed on the lamp holder. The connecting seat is provided with a guide groove for the radial translation insertion of the conductive needle. The buckle has a buckle arm. The clasp arm has a first working position close to the guide groove and a second working position away from the guide groove; when in the first working position, the clasp arm blocks the side of the conductive needle facing the notch of the guide groove.

During installation, the conductive pins at both ends of the lamp tube move along the direction of the guide groove on the connecting seat, and the clasp arm leaves the first working position, so that the conductive pin can reach the bottom of the guide groove. When the conductive pin reaches the specified position, the clasp arm returns Go to the first working position, clamp the conductive needle between the bottom of the groove and the buckle arm, and complete the installation of the lamp tube. The procedure for disassembly is opposite to that for installation. The clasp arm leaves the first working position, so that the conductive needle can move from the bottom of the guide groove to the notch, and then leave the lamp holder, and the disassembly action is completed.

Further, in the above connection structure, the button arm is an elastic button arm, and the elastic button arm has an elastic force to return to the first working position. The design of the elastic buckle arm makes the assembly and disassembly of the lamp tube and the lamp holder more convenient. After the lamp tube is installed, due to the elastic force of the buckle arm, the conductive needle is firmly buckled between the guide groove and the buckle arm, and the structure is stable and easy to contact. good.

Further, in the above connection structure, the surface of the clasp arm in contact with the conductive pin is an inclined slope surface. Utilizing the inclined slope, when the conductive pin moves in the guide groove until it hits the clasp arm, the conductive pin produces a component force on the clasp arm that makes the clasp arm leave the first working position, which facilitates the loading and unloading of the conductive pin.

Further, in the above connection structure, the buckle is connected to the lamp socket through a return spring. The return spring also has the tendency to keep the clasp arm at the first working position. When the conductor exerts a large force on the clasp arm, in addition to the elastic deformation and movement of the clasp arm due to external force, the return spring can also provide a certain displacement space for the clasp. Thereby reducing the deformation of the clasp arm and prolonging the service life of the clasp arm.

Further, in the above connection structure, the buckle is sandwiched between the connection end and the end of the lamp tube.

The utility model has the advantages of:

1. Compared with the existing connection structure between the lamp tube and the lamp holder, the utility model only needs a simple movement of translating the lamp tube to accurately hold the lamp tube during installation, and does not need to rotate back and forth after installing the lamp tube to obtain correct positioning.

2. The clamping device of the utility model firmly clamps the lamp tube, and is not easy to loosen, thereby causing the problem of poor contact of the lamp tube.

Detailed ways

Embodiment: As shown in Fig. 1 to Fig. 5 and Fig. 6d, a connection structure between a lamp tube and a lamp holder, comprising a lamp tube 1 with conductive pins 11 at both ends and a lamp holder 2 with connecting ends 21 at both ends, the lamp tube The conductive pins 11 at both ends are respectively installed on the connection ends 21 at both ends of the lamp holder. The connection ends 21 include a connection seat 211 fixed to the lamp holder 2 and a buckle 213 installed on the lamp holder 2. The connection seat 211 There is a guide groove 2111 for the radial translation insertion of the conductive needle 11. In this embodiment, the guide groove 2111 is a vertical groove with the opening facing downward.

The buckle 213 described in this embodiment is a T-shaped elastic member located between the connecting end 21 and the end of the lamp tube 1 , and its T-shaped upper end is connected to the lamp holder 2 through the return spring 212 . Both ends of the T-shaped upper portion extend downwards to form a clasp arm 2131 , and the lower end of the clasp arm 2131 has a hook bent toward the direction of the guide groove 2111 . During use, the conductive needle 11 is in contact with the hook. As shown in FIG. When in contact with the conductive needle, the upper surface and the lower surface of the hook part are inclined slopes, so that the force exerted by the conductive needle moving up and down on the hook part will generate a component force on the inclined slope surface that makes the hook part move away.

The clasp arm 2131 has a first working position where the above-mentioned hook is close to the guide groove 2111 and a second working position away from the guide groove 2111; when it is in the first working position, the clasp arm 2131 is blocked by the conductive needle 11 Towards the side of the guide groove 2111 notch. The clasp arm 2131 has elastic force to return to the first working position.

The installation process of the lamp tube and the lamp holder in this embodiment is shown in Figure 6a to Figure 6d: in Figure 6a, the lamp tube is moved towards the lamp holder, so that the conductive pin on the lamp tube is located under the hook of the clasp arm in the guide groove ( As shown in Figure 6b), then the conductive pin exerts an upward force on the buckle, which makes the hook of the buckle arm open outwards, and at the same time the buckle retreats upward as a whole (as shown in Figure 6c), and the conductive needle continues to move upwards and crosses the After the upper surface of the hook part, the hook part of the buckle arm returns to the first working position under the action of elastic force, so that the hook part is located under the conductive needle, and at the same time, the buckle returns to the original position under the action of the return spring, so that the conductive needle It is clamped between the guide groove and the buckle arm (as shown in Figure 6d).

The disassembly process of the lamp tube and lamp holder in this embodiment is shown in Figure 7a to Figure 7d, the process is opposite to the installation of the lamp tube: pull down the lamp tube, so that the conductive pin exerts a downward force on the hook, and this force also makes the clasp arm Open it, let the conductive needle pass through, and return it.
