Signal converter

Technical Field

The utility model relates to a signal converter technical field, concretely relates to signal converter.

Background

For an LED lamp with a small-size point light source, the LED circuit arrangement usually adopts a low-voltage (for example, 5V) design under the condition of limited space, and when the LED lamp is applied in a project, the lamp is subjected to multipoint cascade control, the transmission distance of a signal loop is long, and a DMX signal converter is required to be added to realize normal lamp cascade control. The signal converter needs a good moisture-proof effect to ensure that the signal converter is not affected by a damp environment.

At present, the sealing is guaranteed to seal through the mode that need paste the sealing washer on the side cap or beat sealed glue usually by current technical scheme, but the sealing performance and the humidity resistance of above-mentioned two kinds of structures are all relatively poor, and the former needs additionally to tailor the sealing washer, and the latter just can not be taken apart easily in case seal up, is unfavorable for maintaining.

In conclusion, a signal converter sealing structure with good sealing effect and good moisture-proof effect needs to be designed.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to the above problems occurring in the prior art, and provides a signal converter.

In order to realize the purpose of the utility model, the utility model adopts the following technical scheme: a signal converter comprises an aluminum shell and side covers arranged at two ends of the aluminum shell, wherein a sealing assembly is arranged on one side of each side cover facing the aluminum shell, each sealing assembly comprises a sealing baffle frame in butt fit with the inner wall of the aluminum shell and a plurality of sealing frames arranged on the sealing baffle frames, and the outer surfaces of the sealing frames protrude out of the surfaces of the sealing baffle frames; sealed frame that keeps off extends towards the inside direction of aluminum hull, and sealed frame keeps off even interval setting of frame length direction along sealed.

The working principle and the beneficial effects are as follows: during installation, the sealing frame in the sealing assembly is fixedly installed on the sealing baffle frame through pre-processing, and then the sealing baffle frame is directly installed on the side cover, so that the assembly and disassembly are convenient, the sealing ring does not need to be cut manually, manual or machine sealing glue is not needed, the operation is convenient, additional refitting processing on the aluminum shell and the side cover is not needed, the upgrading on the existing product is realized, and the cost is lower; can show sealed effect and the dampproofing effect of promotion through a plurality of sealed frames.

Furthermore, the sealing blocking frame is fixed with the side cover in a combined mode of one or more of glue fixing, double-sided glue fixing and screw fixing. This setting up the installation that conveniently seals the fender frame, need not to process the side cap through the lathe simultaneously and reform transform, reform transform with low costsly, especially can need not to reform transform the side cap through sealed glue or double faced adhesive tape is fixed, can conveniently will seal the fender frame and install on the side cap, does not influence the structure of side cap and aluminum hull simultaneously.

Furthermore, the number of the sealing frames is three, and the sealing frames are respectively an activated carbon frame, a silica gel frame and a rubber frame along the direction from the side cover to the aluminum shell. This setting, prevent the line through three sealing frame, the active carbon has good drying and adsorption effect, can play the dampproofing effect that is showing, silica gel also has good water absorption and can closely butt with the aluminum hull inner wall, show and promote sealing performance, the last rubber frame of rethread can further promote sealing performance, compare the mode of traditional single sealing washer, sealing effect is better, and can directly form with equipment integrated into one piece, it is good to process sealing assembly in advance, then with sealing assembly again with the side cap fixed can, can realize assembly line production, machining efficiency is showing and is improving. Wherein, the three sealing frames are directly and tightly sleeved on the sealing baffle frame and can be fixed by adhesive tape or glue or not fixed.

Furthermore, cobaltous chloride is added into the silica gel material of the silica gel frame. Cobaltous chloride is blue when anhydrous, becomes pink after absorbing water, so silica gel as the water absorbent is pink after absorbing water, can check the colour of silica gel frame and judge that can change the silica gel frame when maintaining.

Further, the rubber frame is made of one of HNBR hydrogenated nitrile rubber, IIR butyl rubber sealing rings and PU polyurethane rubber sealing rings. The rubber frame made of the materials has excellent sealing performance and long service life, and can remarkably improve the sealing performance and the moisture-proof performance of the driving power supply.

Furthermore, the outer size of the sealing baffle frame is smaller than the inner wall size of the aluminum shell by 0-0.1 mm. This setting can conveniently seal and keep off the frame and insert in the aluminium casing, realizes sealed operation through sealed frame.

Furthermore, the inner ring of the sealing baffle frame is provided with a sealing baffle edge which is abutted with the side cover. This setting, if it is sealed fender frame through the screw fixation on the side cover alone, then can effectively promote the sealing performance between sealed fender frame and the side cover through sealed flange, prevent that external moisture from entering into in the inner wall that sealed kept off the frame from both clearance.

Furthermore, the sealing flange and the sealing flange frame are integrally formed. With the arrangement, the sealing performance can be obviously improved.

Further, the sealing rib is made of hygroscopic material. This setting can further promote dampproofing effect.

Furthermore, a plurality of mounting grooves for mounting the sealing frame are formed in the sealing blocking frame. This setting can make things convenient for the installation of sealed frame greatly for sealed frame can need not to fix on sealed fender frame through glue etc. only need overlap in the mounting groove, and hug closely with the mounting groove can.
