Based on the embodiments in the embodiment, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention.

In the following description, the appearances of the indicating orientation or positional relationship, such as the terms "inner", "outer", "upper", "lower", "left", "right", etc., are only for convenience in describing the embodiments and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and are not to be construed as limiting the invention.

Example 1:

referring to fig. 1-4, the present embodiment provides a novel self-shorting aerial pod, which includes two self-shorting aerial pod electrical connectors and a self-shorting aerial pod protective housing.

The self-short circuit aviation plug electric connector comprises a conductive surrounding wall B1, an elastic sheet B2, a mandril B3 and an electric connector body B4.

In the two self-short-circuit aerial-plug electric connectors, one electric connector body B4 is provided with a jack corresponding to the self-short-circuit aerial-plug electric connector as a socket, and the other electric connector body B4 is provided with a contact pin corresponding to the self-short-circuit aerial-plug electric connector as a plug.

The electric connector body B4 is roughly cuboid, a plurality of wire fixing holes B5 are sequentially arranged on the side wall of the electric connector body B4 along the axis of the electric connector body B4, a plurality of wire inlet holes B6 are sequentially arranged on the bottom wall of the electric connector body B4 along the axis of the electric connector body B4, the number of the wire inlet holes B6 is the same as that of the wire fixing holes B5, and each wire inlet hole B6 is provided with a corresponding wire fixing hole B5. The present embodiment is illustrated with one set of wire fixing holes B5 and wire inlet holes B6.

A conductive enclosure wall B1 is mounted within wire entry hole B6. The side walls of the socket are fixed to conductive walls B1 in the socket and the pins are fixed to conductive walls B1 in the header. The axial direction of the wire fixing hole B5 and the axial direction of the wire inlet hole B6 are perpendicular to each other. The side wall of the conductive surrounding wall B1 is provided with a first guide hole B7, the inner wall of the wire inlet hole B6 is provided with a second guide hole B8 communicated with the first guide hole B7, the outer end opening of the wire fixing hole B5 is located on the outer wall of the electric connector body B4, and the second guide hole B8 is located at the inner end opening of the wire fixing hole B5 in this embodiment. The wire fixing hole B5 communicates to the middle of the conductive surrounding wall B1 through the second via B8 and the first via B7.

The ejector rod B3 penetrates through the first guide hole B7 and the second guide hole B8, the outer end of the ejector rod B3 is located in the wire fixing hole B5, the inner end of the ejector rod B3 is located in the middle of the conductive surrounding wall B1, the ejector rod B3 is axially and adjustably mounted at the wire fixing hole B5, and the ejector rod B3 moves in the axial direction of the ejector rod B3 to change the position of the inner end of the ejector rod B3 in the middle of the conductive surrounding wall B1. The fixed end B10 of the spring plate B2 is installed on the electric connector body B4, the moving end B9 of the spring plate B2 is positioned in the middle of the conductive surrounding wall B1, and the inner end of the ejector rod B3 is extruded on the moving end B9 of the spring plate B2. The ejector pin B3 moves axially to control the deformation degree of the spring plate B2, thereby adjusting the position of the moving end B9 of the spring plate B2 in the middle of the conductive surrounding wall B1.

The cable end part B17 is arranged in the middle of the conductive surrounding wall B1, the cable end part B17 is positioned between the moving end B9 of the elastic sheet B2 and the inner wall of the conductive surrounding wall B1, the inner end of the ejector rod B3 and the cable end part B17 are respectively positioned at two sides of the moving end B9, the inner end of the ejector rod B3 extrudes the cable end part B17 on the inner wall of the conductive surrounding wall B1 through the moving end B9 of the elastic sheet B2, and therefore locking of the cable end part B17 in the conductive surrounding wall B1 is achieved. The movable end B9 of the resilient tab B2 corresponds to different degrees of locking to the cable end B17 at different positions in the middle of the conductive enclosure B1. If the elasticity of the elastic piece B2 is reduced, the length of the ejector rod B3 in the middle of the conductive surrounding wall B1 can be increased, and therefore the locking force of the inner end of the ejector rod B3 to the cable end B17 is improved.

As one specific mode of the axial movement adjusting mode of the ejector rod B3, the inner wall of the thread fixing hole B5 is provided with an internal thread, the outer wall of the ejector rod B3 is provided with an external thread section B14, the external thread section B14 is in threaded connection with the internal thread, and the ejector rod B3 is controlled to axially move at the thread fixing hole B5 through the rotation of the ejector rod B3 in the middle of the thread fixing hole B5. Due to the self-locking force between the external thread section B14 and the internal thread, the ejector rod B3 can be effectively prevented from accidentally dropping out of the wire fixing hole B5 when the self-short circuit aviation plug electric connector works. Because the movable end B9 of the elastic piece B2 obstructs the inner end of the ejector rod B3 and the cable end B17, the rotation process of the inner end of the ejector rod B3 acts on the movable end B9 of the elastic piece B2 instead of the cable end B17, and the movable end B9 of the elastic piece B2 can protect the cable end B17. The axial position of the ejector pin B3 is rarely adjusted after the cable end B17 is clamped between the conductive enclosure walls B1.

Preferably, the spring B2 is made of metal, so that the movable end B9 of the spring B2 is electrically conductive, and the movable end B9 of the spring B2 is more wear-resistant and can bear the rotating friction force of the inner end of the ejector rod B3.

The end part of the ejector rod B3, which is located in the wire fixing hole B5, is provided with an arc-shaped screw cap B16, the inner wall of the wire fixing hole B5 is provided with a clamping plane B11, the clamping plane B11 is located on one side, away from the conductive surrounding wall B1, of the internal thread, and the arc-shaped screw cap B16 is extruded on the clamping plane B11. Due to the fact that the shape of the arc-shaped nut B16 is not matched with that of the clamping plane B11, when the ejector rod B3 rotates at the wire fixing hole B5, large resistance can be generated between the arc-shaped nut B16 and the clamping plane B11, and the axial positioning effect of the ejector rod B3 is further improved. A greater rotational force is required to be applied to the arc nut B16 in response to the axial position adjustment of the post rod B3. The clamping action between the arc-shaped screw cap B16 and the clamping plane B11 can also prevent the ejector rod B3 from falling from the wire fixing hole B5 after the internal thread and the external thread section B14 are separated.

In the process of adjusting the axial position of the ejector rod B3, the ejector rod B3 needs to move at the first guide hole B7 and the second guide hole B8, in order to avoid the influence of the ejector rod B3 on the inner wall of the first guide hole B7 and the inner wall of the second guide hole B8, the outer wall of the ejector rod B3 of the embodiment is provided with a smooth section B12, the arc-shaped screw caps B16 and the smooth section B12 are respectively positioned at two sides of the external thread section B14, the smooth section B12 is inserted at the first guide hole B7 and the second guide hole B8 in a penetrating manner, and the smooth section B12 does not influence the first guide hole B7 and the second guide hole B8 in the rotating. Meanwhile, the smooth section B12 is attached to the inner wall of the first guide hole B7, and can radially position the conductive surrounding wall B1. The smooth section B12 can also guide the ejector rod B3 in the process of being installed in the wire fixing hole B5, and the external thread section B14 and the internal thread are prevented from sliding.

The shape of the inner wall of the wire inlet hole B6 is matched with the shape of the outer wall of the conductive surrounding wall B1, so that the conductive surrounding wall B1 is clamped on the inner wall of the wire inlet hole B6, and the inner wall of the wire inlet hole B6 positions the conductive surrounding wall B1 in the axial direction and the circumferential direction of the ejector rod B3. The ejector rod B3 is matched with the inner wall of the wire inlet hole B6, so that the conductive surrounding wall B1 is fixed in the wire inlet hole B6, the relative position between the movable end B9 of the elastic sheet B2 and the inner wall of the conductive surrounding wall B1 is stabilized, and the positioning effect on the cable end B17 is ensured.

Based on the structure, the fixed end B10 of the elastic piece B2 is mounted on the conductive surrounding wall B1 to fix the position of the fixed end B10 of the elastic piece B2 on the electric connector body B4, so as to limit the moving range of the moving end B9 of the elastic piece B2 in the middle of the conductive surrounding wall B1.

The fixed end B10 of the elastic sheet B2 is attached to the outer wall of the conductive surrounding wall B1, and the movable end B9 is located in the middle of the conductive surrounding wall B1 through bending deformation of the elastic sheet B2. The part of the elastic sheet B2 between the fixed end B10 and the movable end B9 is an avoiding plate B13, and the avoiding plate B13 avoids the conductive surrounding wall B1. The smooth section B12 of the ejector pin B3 penetrates through the fixed end B10 of the spring plate B2, so that the smooth section B12 penetrates through the first guide hole B7, and the smooth section B12 positions the fixed end B10 of the spring plate B2 in the radial direction of the ejector pin B3.

The end face of the conductive surrounding wall B1 is a plane, the avoiding plate B13 is attached to the end face of the conductive surrounding wall B1, the end face of the conductive surrounding wall B1 positions the elastic sheet B2 in the circumferential direction of the ejector rod B3, so that the inner end of the ejector rod B3 is always aligned to the movable end B9 of the elastic sheet B2 in the axial direction of the ejector rod B3, and the adjusting effectiveness of the ejector rod B3 on the movable end B9 is guaranteed.

The self-short-circuit aviation plug protective shell comprises a separation lug A6, a rotating piece A11, a lower shell and an upper shell A1.

The top of casing is provided with first mounting groove down, and the plug passes through screw fixed mounting in first mounting groove department.

Specifically, the lower housing includes a bottom panel a2 and a perimeter edge A3. The mounting hole has been seted up in the centre of bottom plate A2, and the mounting hole runs through bottom plate A2 along bottom plate A2's normal direction, and surrounding edge A3 is located bottom plate A2's top, and surrounding edge A3 encircles the edge at the mounting hole and fixes on bottom plate A2, and first mounting groove is enclosed by surrounding edge A3 and is formed, and corresponding mounting hole is located the bottom open position of first mounting groove and directly communicates with first mounting groove. The skirt a3 protects the plug while the cable end B17 can make electrical connection with the plug via the mounting opening.

The bottom of the upper shell A1 is provided with a second mounting groove, and the socket is fixedly mounted at the second mounting groove through screws. The socket is protected by the side wall of the second mounting groove. The cable end B17 may enter the upper housing a1 through an opening in the top of the upper housing a1 to make electrical connection with the receptacle.

The plug is aligned with the socket, and the upper shell A1 is closed to the top of the surrounding edge A3, so that the plug is plugged on the socket, and the top opening edge side wall of the first mounting groove and the bottom opening edge side wall of the second mounting groove are sealed in a splicing mode. The connection strength after the plug and the socket are plugged is extremely high, so that the separation between the surrounding edge A3 and the upper shell A1 is difficult.

The lower case has a rotation axis thereon, and the rotation member a11 is rotatably provided on the lower case about the rotation axis. Specifically, the outer wall of surrounding edge A3 is provided with the protruding axle, and the axis of rotation is the axis of protruding axle promptly, rotates and is provided with the rotation hole on the piece A11, and the protruding axle is pegged graft in rotation hole department, rotates piece A11 and passes through the protruding axle rotation and set up on the outer wall of surrounding edge A3.

The rotation member a11 includes a control portion a4 and a pressing portion a5, and the rotation axis is located between the control portion a4 and the pressing portion a 5. Accordingly, a rotation hole is provided at a portion of the rotation member a11 between the control portion a4 and the pressing portion a 5. When the control part a4 is rotated toward the bottom plate a2, the pressing part a5 is rotated away from the bottom plate a2, and when the control part a4 is rotated away from the bottom plate a2, the pressing part a5 is rotated toward the bottom plate a 2.

The separation protrusion a6 is fixed on the outer wall of the upper case a1, and the pressing portion a5 is located below the separation protrusion a 6. Pressing the control part a4 toward the bottom plate a2, the pressing part a5 rotates upward and gradually approaches the separation protrusion a6 until the pressing part a5 presses the separation protrusion a6 upward. When the pressing portion a5 just contacts the separation protrusion a6, the entire rotating member a11 does not contact the bottom plate a2 yet, so that the rotation of the control portion a4 toward the bottom plate a2 is hindered only by the blocking action of the separation protrusion a6 against the pressing portion a 5. Then, a larger force is continuously applied to the control part a4 towards the bottom plate a2, so that the pressing part a5 overcomes the connecting force between the plug and the socket to jack up the separation bump a6, the upper shell a1 and the surrounding edge A3 are separated, and the plug and the socket are gradually separated.

In the process that the pressing part A5 presses the separation lug A6, the rotating part A11 is a lever which rotates around the convex shaft, so the distance between the control part A4 and the rotating shaft needs to be larger than the distance between the pressing part A5 and the rotating shaft, the moment arm of the control part A4 side is increased, and the force needed by the control part A4 side when the plug is separated from the socket is reduced.

The rotating member a11 in this embodiment is two in number, and two rotating members a11 are respectively located on the front side and the rear side of the surrounding edge A3. Therefore, in the process of actually splitting the plug and the socket, the rotating part A11 on the front side of the surrounding edge A3 can be controlled firstly, so that the front side of the plug and the front side of the socket are split in advance, and then the rotating part A11 on the rear side of the surrounding edge A3 is controlled, so that the rear side of the plug and the rear side of the socket are split, and the split between the plug and the socket is realized. In addition, the two rotating pieces A11 can be controlled simultaneously, so that the plug and the socket are vertically separated.

In addition, immediately after upper case a1 and surrounding edge A3 separate, control portion a4 rotates to a certain angle towards bottom plate a2 and presses on bottom plate a2, so bottom plate a2 has a limiting effect on control portion a 4. When the control part a4 is pressed on the bottom plate a2, the plug and the socket are not completely separated, the plug is partially plugged on the socket, but the connection strength between the plug and the socket is small, and the complete separation of the plug and the socket can be completed only by directly separating the upper shell a1 and the surrounding edge A3 with small force. By adopting the mode, the upper shell A1 is prevented from directly falling from the lower shell when two rotating pieces A11 are controlled by two hands to detach the plug and the socket, and the upper shell A1 is prevented from being damaged.

The protruding axle quantity of connecting on same rotation piece A11 has two, and two protruding axles are left protruding axle A8 and right protruding axle A9 respectively, and left protruding axle A8 and right protruding axle A9 are located the left and right lateral wall of surrounding edge A3 respectively, and left protruding axle A8 and the coaxial setting of right protruding axle A9, it has two to rotate the hole quantity on the same rotation piece A11, and two rotate the hole and be left rotation hole and right rotation hole respectively, and left protruding axle A8 pegs graft in left rotation hole department, and right protruding axle A9 pegs graft in right rotation hole department. Taking the rotating part a11 at the front side of the surrounding edge A3 as an example, the left convex shaft A8 and the right convex shaft a9 jointly support the rotating part a11, and limit the radial and axial movement of the rotating part a11 on the left convex shaft a, so as to ensure that the pressing part a5 can be pressed onto the corresponding separation lug a 6.

In order to avoid that the rotating piece A11 cannot freely swing on the surrounding edge A3 when the plug is plugged with the socket, the outer wall of the upper shell A1 is provided with a locking block A7, the outer wall of the control part A4, facing to one side of the pressing part A5, is concave inwards to form a locking opening A15, and the side wall of the opening of the locking opening A15, facing to the middle of the locking opening A15, protrudes to form a locking stop A10. Control portion a4 gradually leaves lock opening a15 as lock block a7 rotates toward floor a2, and pressing portion A5 gradually enters lock opening a15 as lock block a7 rotates toward floor a 2. After the locking block a7 leaves the locking opening a15, the control part a4 continues to rotate a certain angle towards the bottom plate a2, and the pressing part a5 can not reach the separation lug a 6. When the lock block a7 is located in the lock opening a15, the lock stopper a10 locks the lock block a7 to the side wall of the lock opening a15, and at this time, the lock stopper a10 cannot go over the lock block a7 only by the gravity of the control unit a4, so that the rotor a11 is locked to the peripheral edge A3 and cannot rotate. When the control part a4 receives a large force to rotate toward the bottom plate a2, the locking stopper a10 goes over the locking stopper a7 by a slight deformation, thereby continuing to rotate toward the bottom plate a 2. Can rely on locking dog A10 to lock last casing A1 and lower casing when plug and socket are not installed to first mounting groove and second mounting groove simultaneously, be convenient for accomodate.

The outer wall of the pressing part A5 is provided with a first separation plane A13, the outer wall of the separation lug A6 is provided with a second separation plane A16, the second separation plane A16 is located above the first separation plane A13, and when the pressing part A5 rotates to the separation lug A6, the first separation plane A13 is attached to the second separation plane A16. At the moment, the pressing part A5 and the separation lug A6 are in surface contact, so that the pressing part A5 is prevented from slipping over the separation lug A6 when rotating upwards, meanwhile, the jacking force of the pressing part A5 to the separation lug A6 is distributed as much as possible, the local stress of the separation lug A6 is reduced, and the service life of the separation lug A6 is prolonged.

Since the separating projection a6 needs to receive an upward force, the reinforcing rib a12 is fixed to the outer wall of the upper case a1, and a portion of the outer wall of the separating projection a6, which is opposite to the second separating plane a16 in the normal upward direction of the second separating plane a16 (i.e., the top outer portion of the separating projection a6 in this embodiment), is fixed to the reinforcing rib a 12. When the pressing part A5 presses the separation bump A6, the component force of the acting force of the pressing part A5 in the normal direction of the second separation plane A16 has the largest influence on the service life of the separation bump A6, and the reinforcing rib A12 can effectively counteract the influence of the component force and effectively prolong the service life of the separation bump A6.

The top outer wall of the convex shaft is inclined towards the middle of the surrounding edge A3 to form a guide mounting surface, the guide mounting surface on the corresponding left convex shaft A8 is a left guide mounting surface A14, and the guide mounting surface on the right convex shaft A9 is a right guide mounting surface 17. The rotating piece a11 of the embodiment is an elastic piece, and the rotating piece a11 is stretched to enable two sides of the rotating piece a11 to be supported on the left guide mounting surface a14 and the right guide mounting surface 17, then the rotating piece a11 is pressed downwards, the rotating piece a11 is further stretched under the guiding action of the left guide mounting surface a14 and the right guide mounting surface 17, so that the rotating piece a11 is separated from the right convex shaft a9 and the left convex shaft A8, and the rotating piece a11 is restored, so that the rotating piece a11 is detached from the surrounding edge A3. When the upper shell a1 is not mounted on the lower shell, the rotating piece a11 is expanded to support the bottom wall of the rotating piece a11 on the left guide mounting surface a14 and the right guide mounting surface 17, then the rotating piece a11 is pressed downwards until the left convex shaft A8 and the right convex shaft a9 enter two rotating holes on the rotating piece a11 respectively, the rotating piece a11 is restored, and the mounting of the rotating piece a11 on the lower shell is completed.
