Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of receptacles for detachable electrical connectors, and particularly relates to a receptacle for a detachable electrical connector. Background Technology
[0002] A detachable electrical connector is an electromechanical component used for the circuit connection and disconnection between electronic equipment in launch vehicles, missiles, or other weapon systems and ground equipment or aircraft pylons. It is a crucial component of the missile's electrical system. Military electrical connectors consist of a plug and a socket. Typically, the socket connects to the rocket, and the plug connects to ground equipment or aircraft pylons. Before missile launch, ground launch equipment transmits electrical signals to the missile's electronic equipment via the electrical contacts in the detachable electrical connector, enabling power supply to the missile and facilitating communication between them. During missile launch, as the missile moves along the aircraft pylon, the detachable electrical connector is pulled apart, and the missile enters automatic control flight mode. Ensuring a reliable connection before launch and enabling rapid and reliable disconnection during launch, while preventing the connector from being ablated by engine flames, is a key aspect of the detachable electrical connector's design. The detachable electrical connector typically consists of a plug and a socket. When a missile is launched, the engine exhaust flame severely erodes the socket mounted on the aircraft pylon. Usually, the socket is burned out after each missile launch, rendering it unusable. Therefore, the socket and the pylon mounted on the aircraft need to be replaced after each missile launch, which is complex and costly to maintain.
[0003] In the prior art, patent document with publication number "CN116014499A" discloses an axially detachable, ablation-resistant shielded electrical connector for missiles and rockets. The connector includes a missile socket, a mounting socket, a detachable adapter plug, and a conductive sealing ring. The missile socket is inserted into one end of the detachable adapter plug, and the mounting socket is inserted into the other end. The separation force between the detachable adapter plug and the mounting socket is greater than the separation force between the detachable adapter plug and the missile socket. After the missile socket, mounting socket, and detachable adapter plug are inserted, the detachable adapter plug is simultaneously located within both the missile socket and the mounting socket, forming a gap between them. The conductive sealing ring is fitted onto the outer wall of the detachable adapter plug, and the conductive sealing ring tightly fills this gap. Using this patented technical solution, the mounting socket in the electrical connector is less affected by engine exhaust ablation, and the mounting socket can be reused after missile launch.
[0004] However, in the above-mentioned detached electrical connectors, the prevention of the connector from burning still depends on the shape, size and material properties of the bracket socket itself. When the bracket socket is flat, small in size and has poor high temperature resistance, the electrical connector will still be burned. Therefore, the above-mentioned technical solutions have limited ability to prevent the detached electrical connector from burning. Summary of the Invention
[0005] To solve the above-mentioned technical problems, the present invention provides a detachable electrical connector socket.
[0006] This invention provides a detachable electrical connector socket, comprising a conductive element, an insulating base, a housing, and an anti-ablation device. The surface of the housing is provided with an actuation guide hole. The anti-ablation device includes a sliding plate, a layer plate, and a ceramic block. The surface of the ceramic block is provided with a guide hole and a positioning platform. The positioning platform is clamped between the sliding plate and the layer plate, ensuring that the distance between the sliding plate and the layer plate is greater than zero. The insulating base is fixedly connected to the actuation guide hole. The layer plate is supported on the surface of the insulating base by a return spring, allowing the sliding plate to be fitted into the actuation guide hole. One end of the conductive element is fixedly connected to the insulating base, and the other end of the conductive element passes through the guide hole.
[0007] The anti-ablation device also includes a guide post, the shelf is fixedly connected to one end of the support post, the other end of the support post is fixedly connected to the slide plate, the surface of the support post is also provided with a bypass hole, one end of the guide post is fixedly connected to the insulating seat, and the other end of the guide post passes through the reset spring and the bypass hole in sequence.
[0008] The number of guide posts is multiple, and the multiple guide posts are evenly divided and distributed on the left and right sides of the insulating base.
[0009] The shelves and supports are manufactured as a single piece.
[0010] The support column and the slide plate are fixed together by riveting.
[0011] The anti-ablation device also includes a core column and a locking sleeve. The surface of the core column is provided with a core-setting guide hole. The layer plate is also fixedly connected to one end of the core column, and the other end of the core column is screwed to the locking sleeve. The core column also passes through the reset spring, the layer plate, the core-setting guide hole and the sliding plate in sequence.
[0012] The layer and the core column are manufactured as a single piece.
[0013] The core and the slide plate are fixed together by riveting.
[0014] The trigger hole is also filled with potting compound, one side of which covers the insulating base, and the other side of which is flush with the edge of the trigger hole opening.
[0015] The housing is also fixedly connected to the tail cover, and the tail cover covers at least one opening of the trigger guide hole.
[0016] The beneficial effects of this invention are as follows: Using the technical solution provided by this invention, the ceramic block itself possesses excellent high-temperature resistance and insulation properties, ensuring reliable electrical connection between the socket and plug of the detached electrical connector. When the socket and plug of the detached electrical connector separate, the ceramic block provides a first barrier against thermal shock, preventing the conductive components from being burned. Since the distance between the sliding plate and the shelf is greater than zero, the air between the sliding plate and the shelf forms a heat-insulating airflow. This heat-insulating airflow reduces the conduction speed of high-temperature heat energy, providing a second barrier against thermal shock and further preventing the detached electrical connector from being burned. Furthermore, the sliding plate and shelf can slide along the trigger hole, converting the impact heat energy generated on the surface of the sliding plate into frictional heat between the sliding plate and the trigger, and the elastic potential energy of the return spring, further mitigating the thermal shock and providing a third barrier against thermal shock, further preventing the detached electrical connector from being burned.

Detailed Implementation
[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings, but the scope of protection claimed is not limited thereto; This invention provides a detachable electrical connector socket, such as Figures 1 to 14 As shown, the device includes a conductive element 1, an insulating base 2, a housing 3, and an anti-ablation device. The surface of the housing 3 is provided with an actuation guide hole 4. The anti-ablation device includes a sliding plate 5, a shelf 6, and a ceramic block 7. The surface of the ceramic block 7 is provided with a guide hole 8 and a positioning platform 9. The positioning platform 9 is clamped between the sliding plate 5 and the shelf 6, and the distance between the sliding plate 5 and the shelf 6 is greater than zero. The insulating base 2 is fixedly connected to the actuation guide hole 4. The shelf 6 is supported on the surface of the insulating base 2 by a return spring 10, and the sliding plate 5 is fitted into the actuation guide hole 4. One end of the conductive element 1 is fixedly connected to the insulating base 2, and the other end of the conductive element 1 passes through the guide hole 8.
[0020] By employing the technical solution provided by this invention, the ceramic block itself possesses excellent high-temperature resistance and insulation properties, ensuring reliable electrical connection between the socket and plug of the detached electrical connector. When the socket and plug of the detached electrical connector separate, the ceramic block provides a first barrier against thermal shock, preventing the conductive components from being ablated. Since the distance between the sliding plate and the shelf is greater than zero, the air between the sliding plate and the shelf forms a heat-insulating airflow. This heat-insulating airflow reduces the conduction speed of high-temperature heat energy, providing a second barrier against thermal shock and further preventing the detached electrical connector from being ablated. In addition, the sliding plate and shelf can slide along the trigger guide hole, converting the impact heat energy generated on the surface of the sliding plate into frictional heat between the sliding plate and the trigger guide, and the elastic potential energy of the return spring, further mitigating the thermal shock and providing a third barrier against thermal shock, further preventing the detached electrical connector from being ablated.
[0021] Specifically, the anti-ablation device also includes guide posts 11. The shelf 6 is fixedly connected to one end of the support column 12, and the other end of the support column 12 is fixedly connected to the slide plate 5.

One end of the guide post 11 is fixedly connected to the insulating base 2, and the other end of the guide post 11 passes through the return spring 10 and the bypass hole 13 in sequence. There are multiple guide posts 11, which are evenly distributed on the left and right sides of the insulating base 2. The shelf 6 and the support column 12 are integrally manufactured. The support column 12 and the slide plate 5 are fixedly connected together by riveting. Using the technical solution of the present invention, the guide post 11 guides the movement of the slide plate 5 and the shelf plate 6 along the touch guide hole 4, so that the impact heat energy can be evenly distributed on the surface of the slide plate 5 and the shelf plate 6, avoiding the return spring 10 from generating an off-center load, thereby preventing the electrical connector from being burned due to local overheating of the slide plate 5 and the shelf plate 6. In addition, the shelf plate 6 can be provided in multiple layers, so that heat insulation airflow is also formed between two adjacent shelf plates 6, further improving the anti-burning effect.
[0022] In addition, the anti-ablation device also includes a core column 14 and a locking sleeve 15. The surface of the core column 14 is provided with a centering guide hole 16. The shelf plate 6 is also fixedly connected to one end of the core column 14, and the other end of the core column 14 is screwed to the locking sleeve 15. The core column 14 also passes through the return spring 10, the shelf plate 6, the centering guide hole 16, and the slide plate 5 in sequence. Preferably, the shelf plate 6 and the core column 14 are integrally manufactured. The core column 14 and the slide plate 5 are fixed together by riveting.
