The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1-5, an on-vehicle USB connector comprises a housing, the housing includes a hollow top shell 1 and a hollow bottom shell 2, the bottom shell 2 is provided with a USB through hole 21 for accommodating USB device insertion, two limiting plates 4 are arranged in a cavity 12 of the top shell 1, the two limiting plates 4 are arranged oppositely, two opposite side walls of the two limiting plates 4 are provided with limiting grooves 41, one end of each limiting plate 4 is movably connected with the inner wall of the bottom of the top shell 1, a top rod 63 is fixed in the middle of each limiting plate 4, the top rod 63 is fixed with a sliding rod 62, the sliding rod 62 is slidably connected with the inner wall of the sliding sleeve 61, and the sliding sleeve 61 is fixed with the inner side.

The USB through hole 21 is located between the two limiting plates 4.

The one end that the mouth can hold USB equipment between two limiting plates 4 stretches into, and it is spacing to control all around for stretching into of USB equipment provides about, for the stability that USB equipment connects, ensures that when the car rocks and vibrates, USB equipment's not hard up, drop or slope can not appear, convenient to use, stability is good.

The two sides of the USB equipment are limited by arranging the limiting plate 4, the limiting groove 41, the first spring 5, the second spring 7 and the like in the connector, so that stable connection of the USB equipment is ensured, and the USB equipment is prevented from loosening or falling off.

During normal use, the both sides wall and the 4 butts of limiting plate of USB equipment for limiting plate 4 can play spacing effect. When the automobile shakes and vibrates in a normal range in a small amplitude, the USB equipment can shake along with the automobile, and the limiting plates 4 on the two sides of the USB equipment play a role in limiting the automobile to shake left and right greatly.

The spring clamp further comprises a first spring 5 and a second spring 7, wherein the first spring 5 and the second spring 7 are respectively located on two sides of the sliding sleeve 61.

One ends of the first spring 5 and the second spring 7 are fixed to the inner side wall of the top shell 1, and the other ends of the first spring 5 and the second spring 7 are fixed to the limiting plate 4.

When the automobile shake or vibrations by a wide margin appear, USB equipment can appear rocking on a large scale thereupon, USB equipment can striking limiting plate 4 this moment, make limiting plate 4 can remove to the corresponding inner wall direction of top shell 1, limiting plate 4 can compress first spring 5 this moment, second spring 7, first spring 5, the temporary deformation of second spring 7 can provide the space of buffering for rocking of USB equipment, simultaneously first spring 5, the reset capability of second spring 7 can make first spring 5, second spring 7 removes to keeping away from the corresponding inner wall direction of top shell 1, and then promote limiting plate 4 and remove to keeping away from the corresponding inner wall direction of top shell 1, thereby drive USB equipment and remove to the direction of keeping away from limiting plate 4. Therefore, the deformation and resetting of the first spring 5 and the second spring 7 provide a buffer space for shaking of the USB device, so as to prevent the USB device from being damaged, and meanwhile, the USB device is prompted to reset, so as to ensure the connection stability.

The limiting groove 41 is preferably an arc-shaped groove.

The end part of the USB device can be buckled by arranging the limiting groove 41, the top of the USB device is limited, and the stability of the USB device when being inserted is further ensured, so that the USB device cannot fall off easily.

A clamping opening is formed between the opposite side walls of the two limiting plates 4, and the clamping opening is gradually reduced from bottom to top.

The clamp mouth is gradually reduced from bottom to top, so that the clamp mouth formed between the two limiting plates 4 is gradually increased from the top to the bottom, the top of the inserted USB equipment can be clamped into the limiting groove 41, the USB equipment is not influenced to be inserted and pulled out, and the USB clamp mouth is convenient to use and high in stability.

The inner wall of the sliding sleeve 61 is provided with a sliding groove, and the sliding rod 62 is connected with the sliding sleeve 61 in a sliding manner through the sliding groove.

When the limiting plate 4 moves towards the direction close to the corresponding inner wall under the impact of the USB equipment, the push rod 63 moves towards the direction close to the inner wall, and at the moment, the push rod 63 pushes the sliding rod 62 to slide along the inner wall of the sliding sleeve 61 and move towards the direction close to the inner wall.

Ejector pin 63 and sliding sleeve 61's sliding connection for limiting plate 4 can remove, and then provides the space of buffering for USB equipment, prevents that USB equipment vibrations by a wide margin and produce great striking, finally causes the damage, and the security performance is high.

The lateral wall of top shell 1 is opened has a plurality of joint mouths 13, is fixed with connecting rod 131 between the both sides wall of joint mouth 13, and connecting rod 131 is located the lower part of joint mouth 13.

The upper portion of joint interface 13 is equipped with joint piece 3, the lateral wall 32 bottom of joint piece 3 with connecting rod 131 is fixed, lateral wall 32 top with top shell 1 is fixed, joint piece 3 is the joint piece 3 that elastic material made. Preferably, the connecting block is made of an elastic rubber material.

The inclined wall 31 of the clamping block 3 inclines from the first spring 5 to the second spring 7 on the same side.

Through setting up joint interface 13, joint piece 3, carry on spacingly to top shell 1 of USB connector, prevent that the USB connector from following car and USB connector junction department landing to influence the normal use of USB equipment.

When in use, the top shell 1 of the USB connector extends into the automobile connector. The connecting block 3 is pressed when the USB connector is inserted into the connecting port, so that the USB connector can smoothly enter the connecting port. After the USB connector gets into the connector, elastic joint piece 3 can push up the connector tightly, carry on spacingly to top shell 1 of USB connector, prevent that the USB connector from following car and USB connector junction department landing.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
