[0002] Currently, in addition to meeting general performance requirements, electrical connectors must also meet the following important requirements: good contact, reliable operation, and convenient maintenance. Their reliability directly affects the normal operation of aircraft circuits and is related to the safety of the entire host. Existing USB electrical connectors, after prolonged use, may experience breakage at the connection point. If loosening or breakage is not addressed promptly, accidents may not be handled in a timely manner. Summary of the Invention

[0003] The purpose of this invention is to provide an electrical connector and a cable connector having the electrical connector, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an electrical connector and a cable connector having the electrical connector, comprising a connector body, a mating connector at the upper end of the connector body, a connecting wire end at the bottom end of the connector body, a wire body at the bottom end of the connecting wire end, a fixing ring frame head at the bottom end of the connector body around the upper end of the connecting wire end, a detection airbag at the upper end of the fixing ring frame head, an installation slot at the middle of the left side of the outer side of the fixing ring frame head, a prompting airbag inside the installation slot, a movable cylinder groove at the right side of the right side of the inner side of the fixing ring frame head, an installation spring at the right side of the inner cavity of the movable cylinder groove, a movable block at the left side of the installation spring, a movable pin at the middle of the left side of the movable block, and air holes at the opposite positions of the right side of the inner cavity of the movable cylinder groove and the right side of the inner side of the fixing ring frame head, located at the detection airbag.

[0005] Preferably, both the fixed ring frame head and the detection airbag are circular ring structures when viewed from above, the cross-section of the fixed ring frame head is concave, and the bottom end of the detection airbag has a connecting through hole at a position relative to the air hole.

[0006] Preferably, the movable cylindrical groove and the movable block are both circular in side view, the movable ejector pin has a conical structure on the left side, the movable ejector pin is made of alloy material, and the movable cylindrical groove has a movable opening in the middle of the left side of the inner cavity, at a position relative to the movable ejector pin.

[0007] Preferably, the outer periphery of the movable block and the inner periphery of the movable cylinder groove are polished, and the mounting spring is made of spring steel.

[0008] Preferably, the left side of the inner cavity of the mounting slot has no obstruction, and the outer perimeter of the warning airbag is coated with a conspicuous paint.

[0009] Preferably, the connector body has a rectangular structure, and several buffer isolation blocks are provided around the inner cavity of the connector body.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. This invention uses screws to install the fixing ring frame head to the bottom center of the connector body. When the connecting wire head becomes loose and falls off after prolonged use, it will contact and squeeze the upper end of the detection airbag. By squeezing the detection airbag, the gas inside the detection airbag is forced into the movable cylinder groove through the air hole. When the air pressure inside the movable cylinder groove increases, it will push the movable block and movable pin to the left, and the left side of the movable pin will contact the indicator airbag, puncturing the indicator airbag. This alerts the staff that the connecting wire head has become loose and needs to be dealt with in time. This prevents the connecting wire head and wire from breaking due to lack of timely treatment, making it impossible to continue working. The early warning system can increase the reliability of use.

[0012] 2. In the process of using the connector body, if it is accidentally impacted by the outside, the connector body will deform, but the deformed part will not come into contact with and squeeze the outside of the working body. The buffer isolation block provides a buffering and isolation protection, which increases the protection of the working body and prevents it from being crushed and damaged by impact during use.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-3 This invention provides a technical solution: an electrical connector and a cable connector having the electrical connector, including a connector body 2, a mating connector 1 at the upper end of the connector body 2, a connecting wire head 3 at the bottom end of the connector body 2, a wire body 4 at the bottom end of the connecting wire head 3, a fixing ring frame head 7 at the bottom end of the connector body 2 around the upper end of the connecting wire head 3, a detection airbag 8 at the upper end of the fixing ring frame head 7, an installation slot 9 at the middle of the left side of the outer side of the fixing ring frame head 7, a prompting airbag 10 inside the installation slot 9, a movable cylindrical groove 12 at the right side of the right side of the inner side of the fixing ring frame head 7, an installation spring 14 at the right side of the inner cavity of the movable cylindrical groove 12, a movable block 13 at the left side of the installation spring 14, a movable pin 11 at the middle of the left side of the movable block 13, and an air hole 15 at the opposite position of the detection airbag 8 at the right side of the inner cavity of the movable cylindrical groove 12 and the right side of the inner side of the fixing ring frame head 7.

[0019] Both the fixed ring head 7 and the detection airbag 8 are circular structures when viewed from above. The fixed ring head 7 has a concave cross-section. The bottom of the detection airbag 8 has a connecting through hole at the position opposite to the air hole 15. The fixed ring head 7 is installed to the middle of the bottom of the connector body 2 by screws. When the connecting wire head 3 becomes loose and falls off after long-term use, it will come into contact with the upper end of the detection airbag 8 and squeeze it. By squeezing the detection airbag 8, the gas in the inner cavity of the detection airbag 8 is squeezed into the movable cylinder groove 12 through the air hole 15. When the air pressure in the inner cavity of the movable cylinder groove 12 increases, it will push the movable block 13 and the movable pin 11 to move to the left, and the left side of the movable pin 11 will come into contact with the warning airbag 10, puncturing the warning airbag 10. This alerts the staff that the connecting wire head 3 has become loose and needs to be dealt with in time. This prevents the connecting wire head 3 and the wire body 4 from breaking due to lack of timely treatment, making it impossible to continue working. The early warning increases the safety of use.

[0020] Both the movable cylindrical groove 12 and the movable block 13 are circular in side view. The movable ejector pin 11 has a conical structure on the left side. The movable ejector pin 11 is made of alloy material. The movable cylindrical groove 12 has a movable opening in the middle of the left side of the inner cavity, which is located opposite to the movable ejector pin 11. In this way, the alloy material increases the service life and strength of the movable ejector pin 11 during use.

[0021] The outer periphery of the movable block 13 and the inner periphery of the movable cylinder groove 12 are all polished. The mounting spring 14 is made of spring steel, which increases the lifespan and elasticity of the mounting spring 14 during use.

[0022] The left side of the inner cavity of the mounting slot 9 has no obstruction, and the outer perimeter of the warning airbag 10 is coated with eye-catching paint, thus increasing visibility during use through the eye-catching material of the spray head.

[0023] The connector body 2 has a rectangular structure, and several buffer isolation blocks 5 are arranged around the inner cavity of the connector body 2. The buffer isolation blocks 5 are made of silicone material. There is a gap between the inner cavity of the connector body 2 and the outer perimeter of the working body 6. In this way, if the connector body 2 is accidentally impacted during use, the outer surface of the connector body 2 will deform, but the deformed part will not come into contact with and be squeezed by the outer surface of the working body 6. The buffer isolation blocks 5 provide buffer protection, increase the protection of the working body 6, and prevent the working body 6 from being squeezed and damaged during use.

[0024] Working principle: This invention uses screws to install the fixing ring head 7 to the bottom center of the connector body 2. When the connecting wire head 3 becomes loose and falls off after prolonged use, it will come into contact with and squeeze the upper end of the detection airbag 8. By squeezing the detection airbag 8, the gas inside the detection airbag 8 is squeezed into the movable cylinder groove 12 through the air hole 15. When the air pressure inside the movable cylinder groove 12 increases, it will push the movable block 13 and the movable pin 11 to move to the left, and the left side of the movable pin 11 will come into contact with the indicator airbag 10, puncturing the indicator airbag 10. This alerts the operator that the connecting wire head 3 has become loose and needs to be dealt with in time. This prevents the connecting wire head 3 and the wire body 4 from breaking due to lack of timely treatment, making it impossible to continue working. The early warning system can increase the safety of use.

[0025] Meanwhile, during the use of the connector 2, if it is accidentally impacted by the outside, the connector 2 will deform, but the deformed part will not come into contact with or be squeezed by the outside of the working body 6. The buffer isolation block 5 provides buffer isolation protection, which increases the protection of the working body 6 and prevents it from being squeezed and damaged by impact during use.

[0026] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
