Description

Technical Field

[0001] The utility model belongs to the technical field of sockets, in particular to a novel military standard socket structure. Background Art

[0002] Aviation plugs are also called aviation plugs (sockets). They are mostly used on airplanes and are now also used in military, railway, electric power and other industries. The shell of aviation plugs is usually made of aluminum alloy, stainless steel, nickel plating, copper and other materials. It is durable and reliable.

[0003] The insulating rubber core of the existing welding type socket is made of rubber, and there is a hanging platform on the terminal that is inserted into the rubber core by squeezing the rubber to deform. There are problems such as inconvenient assembly and low efficiency. At the same time, because the rubber is soft, the holding force of the terminal is poor, which easily causes the terminal to fall off and tilt. In order to solve the above problems, a new military-standard socket structure is proposed. Utility Model Content

[0007] A front rubber core, which is clamped at the upper end of the cavity;

[0008] A rear rubber core is snap-connected to the lower end of the cavity, and a plurality of terminal pins are snap-connected between the front rubber core and the rear rubber core;

[0009] The clamping ring is fixedly mounted on the outer wall of the rear rubber core.

[0010] In a preferred embodiment, a fixing portion is provided at the upper end of the inner wall of the socket shell, and a boss is integrally provided on the outer wall of the front rubber core.

[0011] In a preferred embodiment, a plurality of through holes adapted to the terminal pins are provided inside the front rubber core, and a toothed portion is provided on the inner wall of the through hole, and a clamping portion is provided on the upper end of the outer wall of the terminal pin.

[0012] In a preferred embodiment, a plurality of through holes adapted to the terminal pins are provided inside the rear rubber core, and claws are provided at the upper ends of the through holes, and a recess is provided in the middle of the outer wall of the terminal pins.

[0013] In a preferred embodiment, a limiting platform is provided at the lower end of the inner through hole of the rear rubber core, and a limiting portion is provided at the lower end of the outer wall of the terminal pin.

[0014] In a preferred embodiment, the front rubber core is made of silicone and the rear rubber core is made of plastic.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are: the utility model proposes a new military-standard socket structure.

[0016] 1. When the front rubber core is inserted into the socket shell, the boss on its outer wall contacts the fixed part to achieve extrusion sealing, thus solving the waterproof problem between the rubber core and the socket shell.

[0017] 2. When the terminal pin is inserted into the front rubber core, the toothed portion contacts the engaging portion to achieve extrusion sealing, thus solving the problem of waterproofing the terminal and the rubber core.

[0018] 3. When the terminal pin is inserted into the rear rubber core, the claw inside the rear rubber core enters the recessed part in the middle of the terminal pin, so that the terminal pin will not fall off. After the rear rubber core is fixed to the terminal pin, the limit platform contacts the limit part, so that the terminal will not move upward, thereby fixing the terminal.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The following will be combined Figure 1-4 A ball head grinding device for a rearview mirror bracket according to an embodiment of the utility model is described in detail.

[0026] Example:

[0027] A new type of military-standard socket structure, including:

[0028] The socket shell 1 has a cavity inside, a square seat pad 6 is fixedly installed in the middle of the outer part of the socket shell 1, and the front rubber core 2 is clamped at the upper end of the cavity. The upper end of the inner wall of the socket shell 1 is provided with a fixing part 11, and the outer wall of the front rubber core 2 is integrally provided with a boss 21. When the front rubber core 2 is inserted into the socket shell 1, the boss 21 of the outer wall contacts the fixing part 11 to achieve extrusion sealing, thereby solving the waterproof problem of the rubber core and the socket shell;

[0029] The rear rubber core 4 is snap-connected to the lower end of the cavity. A plurality of terminal pins 3 are snap-connected between the front rubber core 2 and the rear rubber core 4. A plurality of through holes matching the terminal pins 3 are provided inside the front rubber core 2, and a toothed portion 22 is provided on the inner wall of the through hole. A clamping portion 31 is provided on the upper end of the outer wall of the terminal pin 3. When the terminal pin 3 is inserted into the front rubber core 2, the toothed portion 22 contacts the clamping portion 31 to achieve extrusion sealing, thereby solving the problem of waterproofing the terminal and the rubber core.

[0030] A plurality of through holes matching the terminal pins 3 are provided inside the rear rubber core 4, and a claw 41 is provided at the upper end of the through hole. A recess 32 is provided in the middle of the outer wall of the terminal pin 3. The terminal is opened by elasticity when inserted. When the terminal pin 3 is inserted into the rear rubber core 4, the claw 41 inside the rear rubber core 4 enters the recess 32 in the middle of the terminal pin 3, so that the terminal pin 3 will not fall off.

[0031] A limiting platform 42 is provided at the lower end of the internal through hole of the rear rubber core 4, and a limiting portion 33 is provided at the lower end of the outer wall of the terminal pin 3. After the rear rubber core 4 and the terminal pin 3 are fixed, the limiting platform 42 contacts the limiting portion 33, so that the terminal will not move upward, thereby fixing the terminal.

[0032] The clamping ring 5 is fixedly installed on the outer wall of the rear rubber core 4. The front rubber core 2 is made of silicone, and the rear rubber core 4 is made of plastic. The plastic rear rubber core ensures the accurate center distance of the terminal, which can make the plug and the socket fit more smoothly and improve the service life of the product. The insulation performance of the other two materials is stable, and the full inspection process can be eliminated, thereby improving efficiency and reducing costs.

[0033] Working principle:

[0034] When the front rubber core 2 is inserted into the socket shell 1, the boss 21 of its outer wall contacts the fixing part 11 to achieve extrusion sealing, thereby solving the waterproof problem between the rubber core and the socket shell; when the terminal needle 3 is inserted into the front rubber core 2, the toothed part 22 contacts the engaging part 31 to achieve extrusion sealing, thereby solving the waterproof problem between the terminal and the rubber core; when the terminal needle 3 is inserted into the rear rubber core 4, the claw 41 inside the rear rubber core 4 enters the recessed part 32 in the middle of the terminal needle 3, thereby preventing the terminal needle 3 from falling off; after the rear rubber core 4 is fixed to the terminal needle 3, the limiting platform 42 contacts the limiting part 33, thereby preventing the terminal from moving upward, thereby fixing the terminal.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
