CN209960241U - A kind of LED lamp tube metal lamp cap protector - Google Patents

Abstract

The utility model relates to a protective part for a metal lamp holder of an LED lamp tube. Through the supporting function of a supporting mechanism in the axial direction, the impact force in the axial direction is transmitted to other positions of the lamp holder with higher strength (i.e. other positions outside the insulating sheet), thereby preventing the impact force in the axial direction from being directly transmitted to the insulating sheet when the LED lamp tube is vertically touching the ground, causing the insulating sheet to collapse and causing the product to be scrapped. At the same time, the combination of the supporting mechanism and the needle sleeve enables the utility model to have anti-collision performance against lateral forces, thereby having anti-collision performance in both the lateral and axial directions, and realizing all-round protection for the copper needle of the lamp holder. Through the supporting function of the supporting mechanism, the utility model prevents the needle sleeve from contacting the insulating sheet of the lamp holder, effectively preventing the insulating sheet from collapsing due to force, and ensuring the safety of the product during packaging and transportation.

Description

Detailed ways

The present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

In order to solve the deficiencies in the prior art that the impact in the axial direction cannot be effectively protected, the utility model provides a metal lamp cap protector for an LED lamp tube. The anti-collision performance of the impact force in the axial direction can effectively prevent the collapse of the insulating sheet of the lamp cap and ensure product safety during packaging and transportation.

Example 1

As shown in FIG. 2 and FIG. 3 , the metal lamp cap protector of the LED lamp of the present invention includes a needle cover 20 and a support mechanism. The needle cover 20 is connected with the support mechanism as a whole, and the support mechanism extends to the insulating sheet of the lamp head 10 . Other positions other than 11 are in abutting contact; when the supporting mechanism is in abutting contact with the lamp cap 10 , the needle cover 20 does not abutting contact with the insulating sheet 11 of the lamp cap 10 . The implementation of the present invention makes it possible that when the LED lamp tube vertically touches the ground, the support mechanism is in abutting contact with the lamp holder 10 to prevent the needle sleeve 20 from directly impacting or indirectly transmitting the impact force to the insulating sheet 11 through the copper needle 12, resulting in The problem of collapse of the insulating sheet 11 .

In this embodiment, the connection and installation of the present invention and the lamp holder 10 is realized through the needle sleeve 20. Specifically, the needle sleeve 20 and the copper needle 12 of the lamp holder 10 are in an interference fit, and the supporting mechanism can be positioned at the same time. Because of the function of connection and installation, the requirements for the structure are reduced, and more shapes or design structures can be implemented, which can be implemented and selected according to different implementation requirements. For example, the support mechanism can be implemented as a number of support rods extending obliquely to the surrounding, a hollow cover extending and diffusing towards the surrounding, etc., and the outline can be implemented as a cylinder, a circular truncated cone, a truncated cone, a multi-faceted column, a multi-faceted truncated cone, etc., as long as it can provide It is enough to ensure the support effect and ensure that the needle sleeve 20 directly bears or transmits the impact force in the axial direction.

The needle cover 20 is used as a mechanism to connect with the copper needle 12. In theory, as long as the copper needle 12 can be inserted into the needle cover 20 and an interference fit can be achieved, it is implemented as an integrated type with a jack or a slot. Structure or split structure are available. In this embodiment, the needle sleeve 20 is a sleeve corresponding to the copper needles 12 of the lamp cap 10 , and the number of sleeves corresponds to the copper needles 12 of the lamp cap 10 , that is, the number of the copper needles 12 of the lamp cap 10 is two, and the number of sleeves corresponding to the copper needles 12 of the lamp cap 10 is two. Set to two.

In this embodiment, the support mechanism is a support cover 21, and the support cover 21 is specifically implemented as a cylindrical cover to ensure higher strength and a sufficiently large contact area for dispersing the force; the bottom opening of the support cover 21 is provided at the The end surface of the base 10 outside the insulating sheet 11 . The two needle sleeves 20 correspond to the positions of the copper needles 12 and are disposed on the top diameter of the support cover 21 , and the bottom opening of the support cover 21 is sufficiently large to cover the end surface outside the insulating sheet 11 of the lamp cap 10 . Therefore, when subjected to a vertical impact force, the force can be transmitted to the metal part with higher strength on the lamp cap 10 through the side wall of the support cover 21 , and the needle cover 20 no longer directly impacts or indirectly impacts the insulating sheet 11 with conventional impact force. , to ensure that the insulating sheet 11 does not collapse.

Generally, the lamp holder 10 has two structures with different diameters in the front and the rear. In this embodiment, the diameter of the support cover 21 is smaller than that of the structure at the end of the lamp holder 10. Therefore, the bottom opening of the support cover 21 and the end face of the lamp holder 10 Butt contact.

In order to realize that the support cover 21 plays a protective role for the needle cover 20 at the same time, the needle cover 20 extends downward from the inner top surface of the support cover 21 . Under the protection of the support cover 21, the needle cover 20 will not be directly subjected to force, so in this embodiment, it is not necessary to form a fixation between the two sleeves as in the prior art. In the supporting structure, the two sleeves are only in a relatively fixed position by the top surface of the support cover 21, and through the support function of the top surface, they can form mutual restraint in the event of a lateral impact, thus forming an anti-collision performance to prevent lateral impact.

In order to facilitate the observation during installation, the support cover 21 is provided with a through hole 22 corresponding to the position of the needle sleeve 20, through which the position of the copper needle 12 can be observed during installation, which is convenient for installation.

Embodiment 2

The difference between this embodiment and the first embodiment is that the diameter of the support cover 21 is different, the range of the cover is different, and the position where the abutting support is formed on the lamp cap 10 is different. In this embodiment, as shown in FIGS. 4 and 5 , the support mechanism is a support cover 21 , and the support cover 21 is implemented as a cylindrical cover. The bottom opening of the support cover 21 is provided on the step 13 on the side of the lamp holder 10 . That is, when the lamp cap 10 includes two front and rear structural bodies with different diameters, a step 13 is formed between the structural body of the first stage at the end and the structural body of the first stage close to the tube body. The diameter of the support cover 21 in this embodiment is large enough. The diameter of the structure body at the first level is larger than that of the end and smaller than the diameter of the structure at the first level close to the tube body. Therefore, after being installed in place, the bottom opening of the support cover 21 is set on the step 13 on the side of the lamp holder 10 .

Other parts are the same as the first embodiment.

The above-mentioned embodiments are only used to illustrate the present invention, but not to limit the present invention. As long as it is based on the technical essence of the present invention, any changes and modifications to the above-mentioned embodiments will fall within the scope of the claims of the present invention.
