Description

Technical Field

[0001] The utility model relates to the technical field of automobile scales, in particular to an aviation socket component of an electronic automobile scale. Background Art

[0002] Floor scales are also called truck scales. Electronic truck scales frequently bear heavy loads and impact forces during operation.

[0003] It was found that during the use of the electronic truck scale in working condition, the plug on the weighing sensor would become loose every once in a while, and the staff in the factory had to remove the plug and reinstall it;

[0004] Research has found that the reason why the plug of an electronic truck scale is easily loosened when in use is that when a vehicle passes through the electronic truck scale, the electronic truck scale is subjected to a large vibration. The plug on the weighing sensor is easily loosened under the impact and vibration for a long time, resulting in poor contact, which causes the plug to loosen and affects the normal weighing work.

[0005] Therefore, in response to the above problems, we have improved the electronic truck scales within the factory. Utility Model Content

[0035] One end of the socket 1 is a cable end, and the other end is an access end 3. A plurality of reducing pins 4 are arranged in the access end 3. When the reducing pins 4 are inserted into the jack, a certain amount of interference can be given to the inner circumference of the jack 5 by the local reducing portion of the reducing pins 4, so that the two are in close contact, so as to keep the current signal from being disconnected and causing poor contact.

[0036] In order to make the reducing pin 4 have a certain degree of ductility, the reducing pin 4 is made of brass;

[0037] The root of the reducer pin 4 is the reducer portion 41 and the end portion is the straight portion 42. The total length of the reducer pin 4 is set to L, the length of the reducer portion 41 is set to L1, and the straight portion 42 is set to L-L1, then L1=(0.1~0.2)L, and its specific value can be customized according to the use requirements. The reducer portion 41 of the reducer pin 4 has a certain taper, and the taper is 50~100, and its specific taper value can be customized according to the use requirements;

[0038] One end of the plug 2 is a cable end, and the other end is an insertion end 6. The insertion end 6 is provided with a plurality of jacks 5 for inserting the reducing pins 4. The number of the jacks 5 corresponds to the number of the reducing pins 4, for example, 5. The specific value can be selected according to the use requirements.

[0039] In order to keep the socket 1 and the plug 2 at a certain angle after being plugged in, so as to protect the straightness of the reducing pin 4, a positioning latch mechanism is provided on the end surface of the access end 3 of the socket 1 and the end surface of the insertion end 6 of the plug 2;

[0040] The tenon mechanism includes a groove 7 and a flange 8 that can be inserted into the groove 7. The groove 7 is formed on the inner circumference of the access end 3 of the socket 1, and the flange 8 is fixed on the outer circumference of the insertion end 6 of the plug 2. The groove 7 and the flange 8 can be set to a square structure, and the shape is not limited to this, and can also be other shapes;

[0041] In order to prevent the plug 2 and the socket 1 from being easily separated in the plugged state, an anti-loosening connection mechanism is also provided on the outer peripheral surface of the socket 1 to prevent the insertion end 6 of the plug 2 from being loosened from the socket 1 in the plugged state;

[0042] The anti-loosening connection mechanism includes a fastening ring 9, which is formed into a roughly ring-shaped structure, one end of the fastening ring 9 is a fastening connection end 10, and the other end is an abutment end 11, an internal thread 12 is arranged on the inner circumferential surface of the fastening connection end 10 of the fastening ring 9, and an abutment platform 13 whose end surface is abutted by the abutment end 11 of the fastening ring 9 is fixedly arranged on the outer circumferential surface of the plug 2, and the abutment platform 13 is formed into a roughly circular abutment platform 13, and an external thread 14 that can be screwed with the internal thread 12 is fixedly arranged on the outer circumferential surface of the socket 1;

[0043] It should be noted that the fastening ring 9 can maintain the tightness of the connection between the plug 2 and the socket 1 after being plugged in, and avoid the plug 2 and the socket 1 from being easily separated to the greatest extent, and the fastening ring 9 and the socket 1 are threadedly connected, and the fine pitch thread structure makes it difficult for the fastening ring 9 to be separated from the socket 1;

[0044] A threaded hole 15 is provided at the edge of the fastening connection end 10 of the fastening ring 9. The number and position of the threaded holes 15 can be customized according to usage requirements, such as one or more. The bolt fasteners screwed into the threaded holes 15 can abut against the outer peripheral surface of the plug 2, thereby preventing the fastening ring 9 and the socket 1 from loosening when they are connected as one.

[0045] When the electronic truck scale aviation socket assembly is plugged in:

[0046] (1) First, insert the plug 2 into the socket 1, and keep the reducer pin 4 fully inserted into the socket 5 of the socket 1. Because there is a latch mechanism between the plug 2 and the socket 1, the reducer pin 4 will not be skewed;

[0047] (2) Then, the fastening ring 9 is screwed to the external thread 14 of the socket 1. At this time, the fastening connection end 10 of the fastening ring 9 is threadedly connected to the external thread 14 on the outer peripheral surface of the socket 1, and the abutting end 11 of the fastening ring 9 abuts against the end surface of the abutting platform 13 of the socket 1, thereby maintaining close contact between the plug 2 and the socket 1;

[0048] (3) Finally, the bolt fastener is screwed into the threaded hole 15 on the outer peripheral surface of the fastening ring 9, so that the end of the bolt fastener abuts against the outer peripheral surface of the socket 1, further maintaining a tight fit between the plug 2 and the socket 1.
