Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to a connector with reliable plugging. Background Art

[0002] As electronic devices become increasingly miniaturized and multifunctional, connectors, as an integral component, have a direct impact on the reliability and stability of the entire system. With traditional connectors, plug-in reliability has always been a key concern. However, in actual use, due to factors such as vibration and thermal expansion and contraction, terminal blocks may deviate from their original installation positions. Existing connectors can experience poor contact, leading to unstable signal transmission or data loss.

[0003] Most common connectors on the market today rely on mechanical fastening (such as screws) or snap-on mechanisms to maintain reliable connections. However, in certain environments, such as industrial automation equipment, aerospace, and military equipment, these connection methods may not meet the requirements for long-term stable operation. Furthermore, for portable or mobile devices, users frequently need to plug and unplug them, placing higher demands on connector durability. Summary of the Invention

[0004] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a connector with a simple structure, easy implementation and firm and reliable plugging, which can maintain good connection performance in various complex environments.

[0005] The technical solution of the utility model includes a plug and a socket, the plug including a plug terminal and a plug housing, the socket including a socket terminal and a socket housing, a first mounting cavity for the plug terminal being formed in the plug housing, the plug terminal being installed in the first mounting cavity along the insertion direction of the plug, a first elastic support arm being bent and extended toward the center position on the cavity wall of the first mounting cavity, the top surface of the first support arm elastically pressing against the plug terminal, a first movable gap being formed between the bottom surface of the first support arm and the cavity wall of the first mounting cavity, a first step being formed on the top surface of the first support arm, the first step being abutted against the plug terminal in the opposite direction of the insertion direction to form a positioning; a second mounting cavity for the socket terminal being formed in the socket housing, the socket terminal being installed in the second mounting cavity along the opposite direction of the insertion direction of the socket, a second elastic support arm being bent and extended toward the center position on the cavity wall of the second mounting cavity, the top surface of the second support arm being elastically pressing against the socket terminal, a second movable gap being formed between the bottom surface of the second support arm and the cavity wall of the second mounting cavity, a second step being formed on the top surface of the second support arm, the second step being abutted against the socket terminal in the insertion direction to form a positioning.

[0006] By adopting the above technical solution, by arranging elastic support arms inside the plug shell and the socket shell, a stable contact pressure can be formed between the plug terminal and the socket terminal, and a good electrical contact state can be maintained even under adverse conditions such as vibration or temperature changes, thereby reducing problems such as unstable signal transmission or data loss due to poor contact, thereby improving the plug-in reliability; the movable gap reserved at the bottom of the elastic support arm allows the plug terminal and the socket terminal to move downward during the assembly of the shell, and the corresponding terminal is limited by the step after assembly, which simplifies the assembly process while preventing the terminal from being affected by external forces and moving out of position to a certain extent.

[0007] In a possible design, a first pressing block and a second pressing block are respectively installed in the first movable gap and the second movable gap. The first pressing block and the second pressing block respectively fit the shape of the corresponding movable gap and respectively press against the bottom surfaces of the first support arm and the second support arm.

[0008] With the above design, the top pressure block further stabilizes the position of the support arm, preventing the support arm from deforming or displacing due to temperature changes and material elastic fatigue during long-term use, thereby ensuring that the support arm can always apply constant pressure to the plug terminal and socket terminal.

[0009] In a possible design, the first pressing block and the second pressing block are in abutment contact with each other when the plug and the socket are plugged in.

[0010] With the above design, the positions of the first pressing block and the second pressing block can be maintained during insertion, so that the corresponding support arms act on the corresponding terminals, reducing the loosening of the terminal connection caused by external vibration or other mechanical interference, thereby enhancing the stability of the connector during insertion.

[0011] In a possible design, the first pressing block and the second pressing block are made of rubber material.

[0012] With the above design, the top pressure block made of rubber material has good elasticity, forming an elastic support for the support arm. In a vibration environment, due to the shock-absorbing properties of the rubber material itself, it absorbs the impact force generated during the plugging process, reduces the impact on the support arm, and ensures that the terminal remains in the preset position.

[0013] In a possible design, an elastic snap arm is provided on the plug housing, and a snap protrusion is provided on the elastic snap arm. An oblique snap block is provided on the socket housing, and the snap protrusion and the oblique snap block form a snap fit.

[0014] The above design ensures that the plug and the socket will not be easily separated when plugged in, and the connection will not be easily loosened even in the event of vibration or mechanical shock, thereby improving the reliability of the connector.

[0015] In one possible design, the socket housing is provided with two ridges corresponding to the socket specifications, and the plug housing is provided with guide grooves corresponding to the plug specifications. The ridges are butt-jointed and inserted into the guide grooves to form a connection between the plug and the socket of the corresponding specifications.

[0016] With the above design, plugs and sockets of different specifications are matched with each other through specific ridges and guide grooves. Only the correct specifications can be plugged in, thus avoiding the problem of misplugging due to inconsistent specifications and ensuring the safe operation of the connector.

[0024] like Figure 1-Figure 5The illustrated connector, which features secure insertion, includes a plug 1 and a receptacle 2 that are mutually pluggable. The plug includes a plug terminal 11 and a plug housing 12, while the receptacle includes a receptacle terminal 21 and a receptacle housing 22. The plug portion is configured as follows: a first mounting cavity 121 is formed within the plug housing 12 for accommodating the plug terminal 11. The plug terminal 11 is inserted into the first mounting cavity 121 from the rear of the plug housing 12 along the plug insertion direction. A first elastic support arm 122 extends from the wall of the first mounting cavity 121 toward the center, with the top surface of the support arm elastically pressing against the plug terminal 11 to ensure good contact between the plug terminal 11 and the receptacle terminal 21. A first step 123 is formed on the top surface of the first support arm 122 for contacting the plug terminal 11 in the direction opposite to the insertion direction to provide positioning. A first movable gap 124 is maintained between the bottom surface of the first support arm 122 and the wall of the first mounting cavity 121 to allow the plug terminal 11 to move downward appropriately during assembly. The socket portion is configured as follows: a second mounting cavity 221 for the socket terminal 21 is formed within the socket housing 22. The socket terminal 21 is installed into the second mounting cavity 221 from the rear of the socket housing 22 in the opposite direction of the socket insertion direction. A second elastic support arm 222 extends from the wall of the second mounting cavity 221 toward the center. The top surface of the support arm elastically presses against the socket terminal 21 to ensure good contact between the plug terminal 11 and the socket terminal 21. A second step 223 is formed on the top surface of the second support arm 222, which is used to abut against the socket terminal 21 in the insertion direction to form a positioning. A second movable gap is retained between the bottom surface of the second support arm 222 and the wall of the second mounting cavity 221 to allow the socket terminal 21 to move downward appropriately during assembly. During the plug-in process, the plug terminal 11 and the socket terminal 21 are subjected to forces toward the rear of the plug housing 12 and the rear of the socket housing 22, respectively. At this time, the positioning of the step and the support arm prevents the plug terminal 11 and the socket terminal 21 from excessive displacement and separation from the housing. Even under adverse conditions such as vibration or temperature fluctuations, the elastic support arms maintain stable contact pressure, keeping the plug terminal 11 and the socket terminal 21 in place and ensuring a reliable connection. During terminal assembly, a clearance at the bottom of the elastic support arms allows the plug terminal 11 and the socket terminal 21 to move downward until a step is formed and they engage with the corresponding terminal, simplifying the assembly process while also preventing the terminals from being dislodged due to external forces.

[0025] The first pressing block 13 and the second pressing block 23 are installed in the first movable gap 124 and the second movable gap respectively. The pressing blocks fit the shape of the corresponding movable gaps and press against the bottom surfaces of the first support arm 122 and the second support arm 222 to stabilize the position of the support arms. When the plug and the socket are docked, the pressing blocks can help the support arms to better contact the terminals, ensuring that the plug terminals 11 and the socket terminals 21 remain in place, so that the plug terminals 11 and the socket terminals 21 are in closer contact and the reliability of the contact is improved. When the plug terminals 11 and the socket terminals 21 are subjected to external forces, the pressing blocks can ensure that the support arms are supported on the corresponding terminals, ensuring that the plug terminals 11 and the socket terminals 21 remain in place after each plugging and unplugging. The pressing blocks also help reduce fatigue damage to the support arms, because they can share the stress caused by repeated plugging and unplugging operations to a certain extent, thereby extending the overall service life of the connector.

[0026] When the plug and the socket are connected, the front of the first pressing block 13 contacts the front of the second pressing block 23. The interaction between the two enables them to be pressed tightly against the corresponding support arm, so that the support arm obtains effective support.

[0027] The first and second pressure blocks 13 and 23 are made of a rubber material with excellent elasticity and shock absorption properties. During assembly, the elasticity of the material allows the pressure blocks to fit tightly within the corresponding clearances. In a vibrating environment, the pressure blocks can reduce the impact of vibration on the support arm, ensuring its effectiveness.

[0028] The plug housing 12 is provided with a resilient snap arm 14 with a snap protrusion 141. The receptacle housing 22 is provided with an oblique latch block 24, with which the snap protrusion 141 forms a snap fit. When the plug is inserted into the receptacle, the snap protrusion 141 temporarily compresses the resilient snap arm 14 and passes through the oblique latch block 24. The spring force then releases the spring force, resulting in a stable snap fit. The user can connect the plug 1 to the receptacle 2 with a simple movement, without the need for additional tools or complicated steps.

[0029] The socket housing 22 is provided with two ridges 25 corresponding to the socket specifications, and the plug housing 12 is provided with a guide groove 15 corresponding to the plug specifications. The ridges 25 are inserted into the guide grooves 15 to form a plug-to-socket connection between the plug and the corresponding socket specifications. Ribs 25 and guide grooves 15 of varying specifications can be customized to suit different application requirements, making them suitable for a variety of devices and systems, increasing the versatility and flexibility of the connector. For example, as shown, the heights of the two ridges 25 are not uniform, resulting in a single specification. Furthermore, the combination of the ridges 25 and guide grooves 15 provides a guiding effect, ensuring that the plug 1 is accurately aligned with the socket, preventing misalignment between the plug 1 and the socket 2 and reducing the possibility of misinsertion.
