Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a locking structure for a waterproof push-pull connector with 1 coaxial and 9 signal components. Background Technology

[0002] Connectors, also known as plugs or connectors, generally refer to electrical connectors, which are devices that connect two active devices to transmit current or signals. Connectors are a component frequently encountered by electronic engineers. Their function is to bridge gaps in circuits or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. Connectors are indispensable components in electronic devices. Connector forms and structures are highly diverse, varying depending on the application, frequency, power, and environment. Due to the wide range of applications, connectors are frequently subjected to significant vibration and shock during use. However, existing connectors have limited vibration and shock resistance, generally unable to withstand such impacts, leading to connector loosening. This deficiency limits their application range and often results in intermittent signal interruption due to excessive vibration and shock. Therefore, to improve the vibration and shock resistance and waterproofing of the connection, enabling underwater use, a 1-coaxial 9-signal mixed-assembly waterproof push-pull connector with a locking structure is needed.

[0018] The following will be based on the embodiments of this utility model. Figure 1 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art. It should be noted that in this invention, "front end" or "front" refers to the end opposite to the socket end and the plug end, such as... Figure 1 The right side of the socket and the left side of the plug; "rear end" or "back" refers to the opposite end of the socket and plug, such as... Figure 1 The left side of the socket and the right side of the plug.

[0019] like Figure 1 A locking structure for a 1 coaxial 9 signal mixed waterproof push-pull connector, including a plug and its matching socket;

[0020] The socket includes a coaxial core assembly 1 and a socket housing 2;

[0021] The plug includes a plug housing 7, a coaxial pin core assembly 9, a spring tube 10, a second locking component, and a third locking component; the inner wall of the socket housing 2 is provided with a slot that matches the spring tube 10;

[0022] When the plug and the socket are engaged, the coaxial pin core assembly 9 is inserted into the coaxial hole core assembly 1, the end of the plug housing 7 is inserted into the socket housing 2, and the spring tube 10 engages with the slot.

[0023] The plug housing 7 is sequentially fitted with the second locking component and the third locking component. The second locking component is used to abut against the spring tube 10 to form a secondary locking; the third locking component is used to abut against the second locking component to form a tertiary locking.

[0024] Both the coaxial core assembly 1 and the coaxial pin assembly 9 are existing technologies, and they are the male and female terminals, respectively. Together, they can transmit radio frequency video signals and +9 signals / currents. It should be noted that the coaxial pin assembly 9 of this invention can be provided with 9 pins to correspond to the transmission of 9 signals, differential signals, currents, etc.

[0025] The front end of the reed tube 10 is provided with an elastic reed. A gap is formed between the reed and the outer wall of the socket housing 2 to provide bending space for the reed. A wedge-shaped part is provided on the reed, and the wedge-shaped part cooperates with the slot to form a locking function.

[0026] This invention forms a primary locking function between the reed tube 10 and the socket housing 2, and then forms a second and third locking function through the second and third locking components respectively. This can effectively improve the stability of the connector, make the connector connection more stable, and prevent it from loosening under vibration and impact.

[0027] Furthermore, the second locking component includes a pressure sleeve 11 and a plug stop nut 12. The reed tube 10 is sleeved on the plug housing 7. One end of the pressure sleeve 11 is sleeved on the plug housing 7, and the other end of the reed tube 10 is sleeved on the rear end of the reed tube 10.

[0028] The plug stop nut 12 is sleeved on the plug housing 7, and the plug stop nut 12 abuts against the end of the pressure sleeve 11 away from the spring tube 10; the pressure sleeve 11 is elastic, and the plug stop nut 12 is used to squeeze the pressure sleeve 11 to generate deformation, thereby making the socket housing 2 and the plug housing 7 tensioned.

[0029] The front end of the reed tube 10 has an "L" shaped structure, and its stepped part is a reed. The rear shield of the reed tube 10 is provided with a limiting part, which is engaged in the groove on the outer wall of the plug housing 7. The limiting part can move back and forth a certain distance in the groove, which serves to constrain the back and forth movement of the reed tube 10.

[0030] The pressure sleeve 11 can be made of rubber. After the coaxial hole core assembly 1 and the coaxial pin core assembly 9 are inserted, the plug stop nut 12 is tightened. The front end of the pressure sleeve 11 abuts against the end face of the socket housing 2. After the pressure sleeve 11 is deformed by force, it can make the socket housing 2 and the plug housing 7 abut against each other and be tightened to form a secondary locking function. It can also further eliminate the front and rear gaps between the socket housing 2 and the plug housing 7.

[0031] Furthermore, the third locking component includes a limiting outer sleeve 15, which is sleeved on the plug housing 7. The limiting outer sleeve 15 abuts against the end of the plug stop nut 12 away from the pressure sleeve 11. A cavity is formed between the limiting outer sleeve 15 and the plug housing 7. A spring 16 is disposed in the cavity. The front end of the spring 16 abuts against the front side of the inner end of the limiting outer sleeve 15, and the rear end of the spring 16 abuts against the tail nut 18. The tail nut 18 is sleeved on the plug housing 7.

[0032] The limiting outer sleeve 15 is connected to the plug housing 7 by a spline. The end of the limiting outer sleeve 15 is provided with a limiting protrusion key. The rear end of the plug stop nut 12 is provided with a protrusion key groove that matches the limiting protrusion key. The limiting protrusion key is inserted into the protrusion key groove to form a rotation limit on the plug stop nut 12.

[0033] The spring 16 causes the limiting protrusion of the limiting outer sleeve 15 to insert into the keyway. In the circumferential direction of the plug stop nut 12, the plug stop nut 12 is locked and cannot rotate, thus forming a triple locking mechanism. When it is necessary to rotate the plug stop nut 12, the limiting outer sleeve 15 can be retracted.

[0034] Furthermore, a first O-ring 4 is provided on the inner wall surface of the socket housing 2, and the first O-ring 4 is used to abut against the outer wall surface of the end of the plug housing 7.

[0035] Furthermore, a slotted nut 6 is fitted onto the socket housing 2. The socket housing 2 has a protrusion, and a second O-ring 5 is provided on the end face of the protrusion. The second O-ring 5 surrounds the socket housing 2, and the slotted nut 6 abuts against the second O-ring 5. An opening is made in the device to which the socket housing 2 is connected; the O-ring is located behind the panel, and the slotted nut 6 is located in front of the panel. Tightening the slotted nut 6 deforms the O-ring to achieve a waterproof effect.

[0036] Both the first O-ring 4 and the first O-ring 4 are used to achieve the sealing function, providing the sealing performance of the connector.

[0037] Furthermore, a wire clamp 17 is fixedly connected to the rear end of the plug housing 7. The function of the wire clamp 17 is to organize and limit the wire harness.

[0038] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model shall fall within the protection scope defined by the claims of the present utility model.
