Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to a pressure-resistant electric connector. Background Art

[0002] An electrical connector is a circuit element used for circuit connection. It is mainly used in military systems such as aviation, aerospace, and national defense. Electrical connectors are used in large quantities in various military aircraft and weapon equipment, especially on aircraft. Generally speaking, an aircraft may use hundreds to thousands of electrical connectors, involving tens of thousands of circuits. Therefore, the connection quality of the electrical connector is very important. In addition to meeting general performance requirements, an especially important requirement is that the electrical connector must have good contact, reliable operation, and easy maintenance. Whether it works reliably or not directly affects the normal operation of the aircraft circuit and involves the safety of the entire host.

[0003] In Chinese utility model patents, such as the utility model of CN218569440U, a pressure-resistant electrical connector is disclosed. The plug housing and the socket housing rotate relative to the socket and the plug, and the deformation of the buffer screw is coordinated to offset the external pressure, thereby preventing the pin and the socket from being damaged due to the external pressure, thereby preventing the device from being damaged. Although the electrical connector ensures the pressure resistance between the plug and the socket, it is weaker than the overall pressure resistance of the electrical connector. When the load-bearing connector assembly is subjected to a large external force, the shell is easily deformed or even punctured, affecting the service life. In severe cases, it may even be crushed by heavy objects, affecting the normal operation of the equipment. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A pressure-resistant electrical connector comprises an upper shell 1 and a lower shell 2. The upper shell 1 is connected to the lower shell 2 by two fixing devices. A male plug 10 is provided on one side of the upper shell 1, and the male plug 10 extends into the lower shell 2. A female connector 7 is provided in the lower shell 2. Two buffer devices are symmetrically provided in the lower shell 2. A load-bearing plate 6 is commonly connected between the two buffer devices. A load-bearing device is connected to the output end of each buffer device. A rubber pad 12 is commonly connected between the two load-bearing devices. A plurality of heat dissipation holes are evenly opened on the rubber pad 12. It should be noted that the rubber pad 12 can provide buffering protection for the joint in the lower shell 2, and the plurality of heat dissipation holes can provide heat dissipation treatment for the joint in the lower shell 2.

[0023] Each fixing device includes a first fixing block 3 and a second fixing block 4, and the first fixing block 3 is fixedly installed on one side of the lower shell 2, and the second fixing block 4 is installed on one side of the upper shell 1, the second fixing block 4 is threadedly connected with a threaded rod 5, and each threaded rod 5 is provided with a rotating handle at one end away from the first fixing block 3, and the threaded rod 5 is threadedly connected to the first fixing block 3 at one end away from the second fixing block 4. It should be noted that the first fixing block 3 and the second fixing block 4 can be connected by the threaded rod 5, so the lower shell 2 and the upper shell 1 are connected synchronously to prevent the male plug 10 from being separated from the female connector 7 due to the shaking of the equipment.

[0024] Each buffer device includes a connecting column 15, and the connecting column 15 is fixedly mounted on the inner bottom wall of the lower shell 2. A spring 9 is sleeved on the outer wall of the connecting column 15, and one end of the spring 9 is fixedly connected to the bottom wall of the lower shell 2. The end of the spring 9 away from the inner bottom wall of the lower shell 2 is fixedly connected to a mounting block 13, and the mounting block 13 is slidably sleeved on the outer wall of the connecting column 15. The upper end face of the mounting block 13 is fixedly mounted with a mounting column 14, and the output end of the load-bearing device is slidably sleeved on the outer wall of the mounting column 14, and the mounting column 14 is slidably sleeved on the outer wall of the connecting column 15, and the lower end face of the load-bearing plate 6 is fixedly connected to the upper end face of the mounting column 14. It should be noted that when the load-bearing plate 6 compresses the spring 9 through the mounting column 14 and the connecting column 15, the spring 9 can buffer the force transmitted by the load-bearing plate 6 to prevent external pressure from directly acting on the joint inside the lower shell 2.

[0025] Each load-bearing device includes two fixed columns 8, and each fixed column 8 is symmetrically fixedly installed on the inner bottom wall of the lower shell 2. The upper end surfaces of the two fixed columns 8 located on the same side are commonly fixedly installed with a connecting plate 11, and the connecting plate 11 is slidably mounted on the outer wall of the corresponding mounting column 14.

[0026] When the utility model is in use, the male plug 10 of the upper shell 1 is first connected to the female connector 7 inside the lower shell 2, and then the threaded rod 5 is screwed to connect the threaded rod 5 on the second fixing block 4 to the first fixing block 3, thereby completing the fixed connection between the upper shell 1 and the lower shell 2.

[0027] When external pressure is transmitted to the internal joint through the lower shell 2, causing the lower shell 2 to deform or puncture, the load-bearing plate 6 will drive the mounting column 14 and the mounting block 13 to compress the spring 9. At this time, the spring 9 is compressed. At the same time, according to the elastic characteristics of the spring 9, the spring 9 rebounds under force, which can buffer the pressure transmitted by the load-bearing plate 6. Subsequently, the load-bearing plate 6 will resist the rubber pad 12 under the action of pressure. Since the rubber pad 12 has a certain elasticity, it can provide a certain protection for the joint inside the lower shell 2 to prevent the load-bearing plate 6 from contacting the joint inside the lower shell 2 and preventing the load-bearing plate 6 from directly acting on the body of the joint due to external pressure. When the buffer device fails, the load-bearing plate 6 will resist the connecting plate 11 under external pressure. At this time, the connecting plate 11 will transmit the pressure transmitted by the load-bearing plate 6 to the entire lower shell 2 through the fixing column 8.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
