The waterproof performance of the waterproof lamp bead of the product is good, the product is a star lamp bead, the product is used outdoors all the year round, and the influence of water resistance on the service life of the star lamp bead needs to be considered. The lamp wick 120 is not wrapped in the AB glue, after the lamp wick is used for a long time, the glue turns yellow and cannot influence the normal colored light of the lamp beads, namely, the colored light which is normally emitted by the product is not influenced by the lamp wick after the lamp wick is used for a long time, and the waterproof structure is simple and the assembly efficiency is high.

In order to facilitate the waterproof lamp bead and the mounting template to be clamped and fixed, in one embodiment, the waterproof lamp bead further includes a clamping structure 150, the clamping structure 150 includes an elastic buckle 151 and a positioning table 152, the elastic buckle 151 and the positioning table 152 are respectively disposed on the outer side wall of the casing 110, and a clamping gap 153 is formed between the elastic buckle 151 and the positioning table 152. In this embodiment, the fastening structure 150 is installed on the first housing 115. Because star lamp pearl is rectangular rope column structure, waterproof lamp pearl need be installed on the installation template of constituteing rectangular rope column structure, so, when with waterproof lamp pearl and installation template chucking fixed connection, the bullet is detained 151 will insert the through-hole of installation template and with a side butt of through-hole, location platform 152 will be in the another side butt of through-hole, make the installation template in the frame region of through-hole be located between chucking clearance 153, thereby detain 151 and location platform 152's combined action at the bullet and fix waterproof lamp pearl chucking on the installation template down.

In one embodiment, the snap 151 is disposed adjacent to the card interface 111. In this embodiment, the first housing 115 is integrally molded with the second housing 116 to form the snap 151. Like this, can be when fixed with waterproof lamp pearl and mounting panel chucking, the through-hole that the mounting panel was passed in deformation can in time take place for the bullet knot 151, so can be fast with waterproof lamp pearl chucking in the mounting panel.

In one embodiment, the number of the snap fasteners 151 is plural, and the plurality of snap fasteners 151 are disposed at intervals on the outer sidewall of the housing 110. So, can improve waterproof lamp pearl and erection template's stability of being connected.

In one embodiment, the elastic buckle 151 is an elastic block structure, and a predetermined angle is formed between the elastic buckle 151 and the outer sidewall of the housing 110. Optionally, the preset included angle is 30 degrees. Optionally, the preset included angle is 45 degrees. Optionally, the preset included angle is 60 degrees. The angle of the preset included angle can be set according to the diameter of the through hole of the mounting template so as to adapt to mounting templates with different sizes.

In one embodiment, the number of the positioning table 152 is plural, and the plurality of positioning tables 152 are disposed at intervals on the outer side wall of the housing 110. In this embodiment, the first housing 115 is integrally formed with the positioning stage 152. So, can improve waterproof lamp pearl and erection template's stability of being connected.

To further improve the stability of the product connection, in one embodiment, each positioning stage 152 corresponds to a snap 151. So, each location platform 152 and a bullet knot 151 carry out the application of force to the regional installation template of through-hole frame jointly, have greatly improved the stability of being connected of waterproof lamp pearl and installation template.

To improve product versatility, in one embodiment, the cross-section of the shell 110 and the cross-section of the wick 120 are both circular structures. That is, the casing 110 and the wick 120 are both cylindrical structures. Therefore, the method can adapt to the conventional design of products and improve the universality of the products.

To improve the waterproof effect, in one embodiment, the inner diameter of the retainer ring 114 is equal to the outer diameter of the wick 120. Further, the sum of the outer diameter of the wick 120 and the height of the limit convex ring 121 is larger than the inner diameter of the limit snap ring 114. Thus, after the wick 120 passes through the clip interface 111, the outer side wall of the wick 120 abuts against the end surface of the limit snap ring 114, and the top end surface of the limit convex ring 121 abuts against the inner side surface of the limit snap ring 114. Thus, between the wick 120 and the casing 110, under the combined action of the limiting snap ring 114 and the limiting convex ring 121, a contact surface of a step structure with two abutting surfaces is formed, and under the fixing action of the filler 140, a stable connection structure is formed between the wick 120 and the casing 110, so that when the wick 120 is used for a long time, the connection structure among the filler 140, the wick 120 and the casing 110 can better prevent external moisture from entering the wick 120 from the joint of the cable 130 and the wick 120, and prevent the wick 120 from short circuit and aging due to moisture, mist and other factors.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent several embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
