Abstract

The utility model provides an LED driver with sealing rings. The LED driver comprises a PCB, and is characterized by comprising two end caps. The periphery of each end cap is provided with a protruded square frame, each square sealing ring is fit with the inner wall of the square frame, the two end surfaces of a tubular shell whose cross section is square respectively abut against the sealing rings at the two sides, each of two fastening bolts penetrates through the through holes in the end caps and the positioning hole in the inner wall of the tubular shell, the fastening bolts are screwed with fastening nuts so that the end caps are fixedly connected with the shell between the end caps, and the PCB is accommodated in the shell. According to the utility model, sealing is realized via the sealing rings instead of glue, and connection is realized via the bolts instead of glue, so that the problems in environmental protection caused by glue can be avoided, the assembly procedures is fewer, and the LED driver can be dismounted for maintenance.

Description

A kind of LED driver with sealing ring

Technical field

The utility model belongs to a kind of LED lamp fitting, relates in particular to a kind of LED driver.

Background technology

The critical piece of LED driver is pcb board, is also printed circuit board (PCB).

Printed circuit board (PCB) comprises a lot of electronic devices and components and circuit, when LED lamp be used in wet environment as bathroom in time, pcb board often damages owing to making moist.

Make moist for fear of pcb board, generally pcb board be arranged on now and in shell, form LED driver,

Shell adopts the form sealing of rubber seal.

But rubber seal form needs rubber seal material, not environmental protection, and rubber seal needs brush coating, the operations such as dry glue, and operation is many, once rubber seal, shell and LED driver just cannot be dismantled, if PCB circuit goes wrong, only have together with shell and change.

Utility model content

The utility model provides a kind of LED driver with sealing ring, its objective is and solves the shortcoming that prior art exists, and makes LED driver easily assembling in protection against the tide heat radiation, easy-maintaining and environmental protection.

The utility model solves the technical scheme that its technical problem adopts:

A kind of LED driver with sealing ring, comprise pcb board, it is characterized in that: there are two end caps, the surrounding of end cap is provided with the square frame of projection, there is the inwall laminating of square sealing ring and square frame, cross section is that two end face contacts of square tubular shell are on the sealing ring of both sides, fastening bolt is through two through hole and set positioning through hole of tubular shell inwall that end cap is set, and fastening bolt and clamp nut screw togather and by two end caps be clipped in two housings between end cap and be connected; Accommodating pcb board in housing.

Usefulness of the present utility model is:

The utility model, owing to using sealing ring sealing to replace original rubber seal, uses bolt to connect and replaces original glue to connect, thus the environmental issue of having avoided rubber seal to produce, and assembling procedure is few, and can detachable maintaining.

Brief description of the drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is end cap of the utility model, sealing ring and pcb board schematic diagram;

Fig. 2 is part-structure schematic diagram of the present utility model (without fastening bolt);

Fig. 3 is outside drawing of the present utility model (without fastening bolt);

Fig. 4 is the cutaway view along fastening bolt axis of the present utility model.

Embodiment

As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, LED driver of the present utility model two ends are two end caps 1, the surrounding of end cap 1 is provided with the square frame 11 of projection, having square sealing ring 2 fits with the inwall of square frame 11, namely in end cap 1, be embedded sealing ring 2, cross section is that two end face contacts of square tubular shell 3 are on the sealing ring 2 of both sides, fastening bolt 4(has two fastening bolts) be provided in a side of in the set projection 31 of the inwall of housing 3 through the set through hole 12 of two end caps 1 and the set positioning through hole 32(positioning through hole 32 of tubular shell 3 inwalls, coaxial with two corresponding through holes 12 of end cap 1), fastening bolt 4 and clamp nut 5 screw togather and by two end caps 1 be clipped in two housings 3 between end cap 1 and be connected, the interior accommodating pcb board 6 of housing 3.

Like this, the space in housing 3, pcb board 6 simultaneously, is just sealed with the combination of sealing ring 2 by housing 3, and on fastening bolt 4 and clamp nut 5, sheathed sealing ring 7 is with further sealing better.

Claims

1. the LED driver with sealing ring, comprise pcb board, it is characterized in that: there are two end caps, the surrounding of end cap is provided with the square frame of projection, there is the inwall laminating of square sealing ring and square frame, cross section is that two end face contacts of square tubular shell are on the sealing ring of both sides, fastening bolt is through two through hole and set positioning through hole of tubular shell inwall that end cap is set, and fastening bolt and clamp nut screw togather and by two end caps be clipped in two housings between end cap and be connected; Accommodating pcb board in housing.
