The utility model aims at providing a dustproof and waterproof's vehicle terminal to solve the not good problem of current vehicle terminal's leakproofness.

The specific scheme is as follows:

the utility model provides a dustproof and waterproof's vehicle-mounted terminal, including the casing that has an inner chamber, install in this inner chamber circuit assembly and with this circuit assembly electric connection's an at least connector, the casing have with the window of the appearance phase-match setting of connector to and the annular rib in this window outside is located to the ring, the connector install in on the window, and the lateral wall of this connector with form an annular first recess between the annular rib, this first recess intussuseption be filled with the connector with clearance seal's between the casing casting glue.

Further, the casing has included last casing and lower casing, have the die cavity that is used for installing circuit assembly and follow the second recess that this lower casing upper periphery set up down on the casing down, install the sealing strip in this second recess, last casing is last to have the rib that corresponds second recess and extrusion sealing strip.

Further, the inner wall of the second groove is higher than the opposite outer wall, and the rib of the upper shell is provided with a first yielding part and a second yielding part which are used for yielding the inner wall and the outer wall of the second groove.

The utility model provides a dustproof and waterproof's vehicle terminal compares with prior art and has following advantage: the utility model provides an annular rib has been add at vehicle-mounted terminal around installation connector's window, so that form annular recess between the outer wall of this annular rib and connector, the intussuseption of clearance seal between connector and the casing is filled in this recess, with realize the sealed between connector and the casing, thereby improve whole vehicle-mounted terminal's sealing performance, it is minimum to fall external environment to the influence of vehicle-mounted terminal inside components and parts, the life and the reliability of product are improved, moreover, the steam generator is simple in structure, and is low in cost, and is stable and reliable.

Detailed Description

To further illustrate the embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1-5, the present embodiment provides a dustproof and waterproof vehicle-mounted terminal, which includes a housing 1 having an inner chamber 10, a circuit assembly 2 installed in the inner chamber 10, and at least one connector 20 electrically connected to the circuit assembly 2, in the present embodiment, the circuit assembly 2 includes a PCB circuit board and a component soldered to the PCB circuit board, and the connector 20 is also soldered to the PCB circuit board.

Specifically, the housing 1 is provided with a window 11 at a position corresponding to the connector 20, the window being configured to match the external shape of the connector 20, where the external shape matching means that the shape of the window 11 is the same as the external shape of the connector 20, but considering the actual assembly and manufacturing errors, a gap exists between the window 11 and the connector 20, and the high-level protection requirement cannot be met only by matching the external shape structure.

Therefore, in this embodiment, an annular rib 12 located at the outer peripheral side of the window 11 is formed on the outer wall of the housing 1, the annular rib 12 is used as a surrounding barrier around the window 11, and forms an annular first groove 13 with the outer side wall of the connector 20 installed in the window 11, the first groove 13 is filled with the potting adhesive 3, the potting adhesive 3 is initially in a liquid state and can flow in the first groove 13, and closely adheres to the outer side wall of the connector 20 and the annular rib 12 of the housing 1, so as to fill the gap between the connector 20 and the window of the housing 1, and after the potting adhesive 3 is solidified, the sealing between the connector 20 and the housing 1 is realized, thereby ensuring the sealing performance of the entire vehicle-mounted terminal, the protection grade of the vehicle-mounted terminal can reach IP65 by the way that the potting adhesive 3 seals the connector 20 and the housing 1, and the influence of the external environment on the internal components of the vehicle-mounted terminal is minimized, the service life and the reliability of the product are improved.

As a preferred embodiment of this embodiment, the housing 1 is composed of an upper housing 1a and a lower housing 1b, and the lower housing 1b has a cavity for mounting the circuit module 2. Have on this lower casing 1b along the second recess 14 that this lower casing 1b upper week set up, install sealing strip 4 in this second recess 14, sealing strip 4 in this embodiment is the silica gel sealing strip. The part of the upper shell 1a corresponding to the lower shell second groove 14 is provided with a rib 15 which is matched with the upper shell and extrudes the sealing strip 4, so that when the upper shell 1a and the lower shell 1b are fixedly installed, the sealing strip 4 can realize the sealing performance of the splicing part of the upper shell 1a and the lower shell 1b, and meanwhile, the circuit assembly 2 is convenient to install. In the present embodiment, the upper case 1a and the lower case 1b are fixed to each other by screws 6.

Preferably, the inner wall 14a of the second groove 14 close to the inner chamber 10 is higher than the opposite outer wall 14b, and correspondingly, the rib 15 of the upper shell 1a has a first relief portion 150 and a second relief portion 151 which are respectively relieved from the inner wall 14a and the outer wall 14b on both sides corresponding to the inner wall 14a and the outer wall 14b of the second groove 14, so that when the upper shell 1a and the lower shell 1b are fixedly installed, the free end of the rib 15 can extend into the second groove 14 to press the sealing strip 4, and the rib 15 and the second groove 14 form a staggered step structure to enhance the sealing performance at the joint of the upper shell 1a and the lower shell 1 b.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
