Description

Technical Field

[0001] The present invention relates to the technical field of electrical connectors, and in particular to a connector assembly. Background Art

[0002] Circular electrical connectors are components used in various electronic devices and systems. In order to meet the needs of the military and aviation fields, circular electrical connectors came into being. They are known for their reliable connection performance and ability to withstand harsh environments. The design feature of circular connectors is that their shells are usually circular. This design is not only easy to install and disassemble, but also provides good mechanical strength and electromagnetic shielding effect to protect the sensitive internal electrical contact parts.

[0003] A Chinese patent document with authorization announcement number CN109066172B discloses an easily disassembled electrical connector, including an electrical connector plug and an electrical connector socket, wherein a first insulator is arranged inside the electrical connector plug, and a first conductive pin and a second conductive pin are respectively penetrated inside the first insulator, the outer surface of the first conductive pin is sleeved with a first insulating sleeve, the outer surface of the second conductive pin is sleeved with a second insulating sleeve, and an annular baffle is arranged on the inner surface of the electrical connector plug and at a position in contact with an end face of the first insulator. In the patent document, the mutual cooperation of two fixed hole plugs and a plurality of springs and annular slide plates can simplify the replacement of the electrical connector, and two fixed hole plugs of different sizes can correctly insert the pins in the electrical connector plug into the corresponding jacks of the electrical connector socket, and the plurality of threads for disassembly arranged on the electrical connector can enable the corresponding damaged parts of the electrical connector to be replaced when it is damaged.

[0004] When using existing connectors, the wires may be subjected to large tensile forces. If the plug of the connector is fixed to the socket by threads, the wires or the device may be damaged. Therefore, to deal with this situation, the plug and the socket are fixed together by damping force. When the wires are subjected to large tensile forces, the plug overcomes the damping force and separates from the socket. The plug will be thrown out at a large speed and may easily hit other devices, causing damage to the plug or the device. Summary of the invention

[0005] The present invention provides a connector assembly, aiming to solve the problem in the related art that when a plug is subjected to a large pulling force and is separated from a female socket, the plug is thrown out at a large speed.

[0006] A connector assembly comprises a circular plug and a female socket, the right end surface of the plug is provided with a connecting sleeve, a pin is provided in the connecting sleeve, and a jack matching the pin is provided on the female socket, a positioning sleeve is coaxially provided on the outer side of the connecting sleeve, and a plurality of clamping components are provided on the inner side of the positioning sleeve, the clamping component comprises an insert block fixedly mounted on the right end surface of the plug and a pin slidably mounted on the inner side surface of the positioning sleeve along the length direction of the positioning sleeve, a slot and an annular groove matching the pin and the positioning sleeve are provided on the female socket, the right end surface of the plug is fixedly connected with an insert block, the insert block and the pin are respectively connected with a spring piece 1 and a spring piece 2, a groove is provided in the slot, and the groove matches the spring piece 1 and the spring piece 2, when the spring piece 1 is located in the groove, the plug and the female socket are connected together, a sliding sleeve is slidably mounted on the plug along its length direction, an elastic member is provided in the plug, and the left end of the pin is connected to the elastic member through a clutch structure, and when the sliding sleeve slides to the left relative to the plug, the clutch structure separates the pin from the elastic member.

[0007] The effect is: when the wire is subjected to a large pulling force, the plug moves to the left relative to the female socket, and the spring piece 1 is deformed and disengaged from the groove. At the same time, the pin and the slider move to the right relative to the positioning sleeve, and the elastic member is stretched by the pulling force of the slider, and finally the spring piece 2 also slides out of the groove. Therefore, when the plug overcomes the damping force and disengages from the female socket, the damping force between the spring piece 2 and the groove and the elastic force of the elastic member buffer the plug, thereby reducing the speed of the plug when it disengages from the female socket, avoiding the plug from being thrown onto other devices at a high speed and causing damage to the plug or the device.

[0008] Preferably, the clutch structure includes a slider slidably installed in the plug, and the slider and the bolt are both provided with matching hooking parts, and the slider is connected to the elastic member. The clutch structure also includes a trigger component for separating the slider and the bolt, so that the hooking parts on the slider and the bolt are hooked or separated from each other, thereby connecting or separating the bolt and the elastic member, thereby switching the state.

[0009] Preferably, the elastic member is an elastic rope, one end of which is fixedly connected to the plug, and the other end of which is connected to the slider, thereby applying a force to the slider toward the pin, so that the hooking parts on the slider and the pin are hooked with each other.

[0010] Preferably, the trigger assembly includes a paddle hinged in the plug, one end of the paddle is in contact with the slider, and a paddle shaft for paddle movement is fixedly mounted on the sliding sleeve. When the sliding sleeve is slid, the paddle is pushed upward by the paddle shaft, so that the slider moves away from the sliding pin, thereby separating the hooking parts on the upper slider and the pin from each other.

[0011] Preferably, the shapes of the spring piece 1 and the spring piece 2 are both spoon-shaped, the elastic coefficient of the spring piece 2 is greater than the elastic coefficient of the spring piece 1, and after the plug and the socket are connected, the spring piece 1 is located in the groove, and a large pulling force is required to make the spring piece 1 escape from the groove.

[0012] Preferably, a wave-shaped protrusion capable of contacting the second spring piece is provided in the slot, and the wave-shaped protrusion is located on the right side of the groove, so that a damping effect is exerted on the second spring piece through the wave-shaped protrusion.

[0013] Preferably, a slide rail is provided on the inner wall of the positioning sleeve, the latch is slidably installed in the slide rail, and the spring sheet 1 and the spring sheet 2 both protrude from the side of the slide rail and the latch close to the axis of the plug.

[0014] Preferably, the positioning sleeve is provided with a limit block for limiting the maximum outward sliding length of the plug pin, and when the plug pin slides outward to the maximum length, the plug pin is separated from the socket.

[0015] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0016] 1. When the wire is subjected to a large pulling force, the plug moves to the left relative to the socket, and the spring piece 1 is deformed and detached from the groove. When the plug overcomes the damping force and detaches from the socket, the damping force between the spring piece 2 and the wavy protrusion and groove, as well as the elastic force of the elastic rope, buffers the plug, thereby reducing the speed of the plug detaching from the socket and avoiding damage to the plug or the device.

[0017] 2. When the detection needs to disconnect, pinch the sliding sleeve to make the plug separate from the female socket, so that the hooking parts on the slider and the plug pin are separated from each other. When the pin is separated from the socket, the second spring piece enters the groove, so that the plug and the female socket are not completely separated and the conductive connection between the two is disconnected, which is convenient for the next insertion.

DETAILED DESCRIPTION

[0027] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] like Figure 1 and Figure 2 As shown, a connector assembly includes a circular plug 1 and a female socket 2, the plug 1 is connected to a wire, and the female socket 2 is connected to a wire or a device ( Figure 2 The female socket 2 shown is connected to the wire).

[0029] like Figure 1 and Figure 2 As shown, the plug 1 includes a housing 11, a connecting sleeve 12, a pin 13, a sliding sleeve 14, a positioning sleeve 15 and three clamping components 16. The connecting sleeve 12, the pin 13 and the positioning sleeve 15 are all fixedly arranged at the right end of the housing 11, and the pins 13 are arranged in the connecting sleeve 12 at equal intervals. The positioning sleeve 15 is located on the outside of the connecting sleeve 12 and the two are coaxially arranged. The outer surface of the sliding sleeve 14 is provided with anti-slip grooves, and the inner side of the sliding sleeve 14 is provided with a guide block (refer to Figure 5 ), a guide groove adapted to the guide block is opened on the shell 11, so that the sliding sleeve 14 is slidably installed on the shell 11, and three clamping components 16 are evenly distributed in the annular cavity between the positioning sleeve 15 and the connecting sleeve 12 for connecting the female seat 2.

[0030] The female base 2 is provided with a socket 21, a slot 22 and an annular groove 23. The socket 21 is adapted to the pin 13, and the slot 22 and the annular groove 23 are adapted to the clamping assembly 16 and the positioning sleeve 15 respectively. The slot 22 is provided with a groove 221 on one side close to the axis of the female base 2, and a wave-shaped protrusion is provided on the right side of the groove 221 (refer to Figure 7 ), a sealing sleeve 24 is provided at the edge of the left end surface of the female seat 2 and is in contact with the outer circumferential surface of the positioning sleeve 15.

[0031] like Figure 1-Figure 4 As shown, the clamping assembly 16 includes an insert block 161, a latch 162, a spring piece 163, a spring piece 2 164, an elastic member 165 and a clutch structure. The insert block 161 and the latch 162 are in contact with each other. The insert block 161 is fixedly mounted on the right end surface of the housing 11. A slide rail is provided on the inner wall of the positioning sleeve 15. The latch 162 is slidably mounted in the slide rail. The spring piece 163 and the spring piece 2 164 are respectively connected to the insert block 161 and the latch 162. The spring piece 1 163 and the spring piece 2 164 are both spoon-shaped and fit with the groove 221 (refer to Figure 6 and Figure 7 ), the spring piece 1 163 and the spring piece 2 164 both protrude from the side of the slide rail and the plug 162 close to the axis of the plug 1, the elastic coefficient of the spring piece 2 164 is greater than the elastic coefficient of the spring piece 1 163, so that the force of the spring piece 1 163 being separated from the groove 221 is greater than the force of the spring piece 2 164 being separated from the groove 221, the elastic member 165 is an elastic rope, one end of the elastic rope is fixedly connected to the inside of the plug 1, and the other end is connected to the plug 162 through a clutch structure. When the sliding sleeve 14 slides to the left relative to the plug 1, the clutch structure separates the plug 162 from the elastic rope.

[0032] The positioning sleeve 15 is provided with a limit block 151 for limiting the maximum length of the latch 162 sliding outward. A limit groove matched with the limit block 151 is provided on the side where the latch 162 contacts the positioning sleeve 15. The limit block 151 and the positioning sleeve 15 are stamped integrally, that is, a connecting piece connected to the positioning sleeve 15 is punched out of the positioning sleeve 15, and the connecting piece is bent inward. Since the connecting piece is elastic, the latch 162 is operated along the inclined direction of the connecting piece during installation, so that the connecting piece passes over the left end of the latch 162 and enters the limit groove. Therefore, when the latch 162 slides outward to the maximum length, the connecting piece abuts against the left end of the limit groove. At this time, the pin 13 is separated from the socket 21.

[0033] The clutch structure includes a slider 166, a paddle 167 and a toggle shaft 168. The slider 166 is slidably mounted in the plug 1. The slider 166 and the latch 162 are both provided with matching hooking parts. The slider 166 is connected to the elastic rope. The paddle 167 is hinged in the plug 1. One end of the paddle 167 contacts the slider 166. The sliding sleeve 14 is fixedly mounted with a toggle shaft 168 for toggling the paddle 167. When the sliding sleeve 14 moves to the left relative to the sliding sleeve 14, the toggle shaft 168 is fixedly mounted on the sliding sleeve 14. , the toggle shaft 168 pushes the paddle 167, and the paddle 167 toggles the slider 166, so that the slider 166 and the hooking parts on the latch 162 are separated from each other, so that the latch 162 is not affected by the elastic rope. When the latch 162 moves to the left for reset, the inclined surface of the hooking part on the latch 162 abuts against the inclined surface of the hooking part on the slider 166, so that the slider 166 moves to make way for the latch 162 until the hooking parts on the slider 166 and the latch 162 are hooked together again.

[0034] Working principle:

[0035] When the wire is subjected to a large pulling force, the plug 1 moves to the left relative to the female socket 2, and the spring piece 1 163 is deformed and disengaged from the groove 221. At the same time, the plug 162 is subjected to the damping force of the wavy protrusion in the groove 221, and the plug 162 and the slider 166 move to the right relative to the positioning sleeve 15. The elastic rope is stretched by the pulling force of the slider 166, and finally the spring piece 2 164 also slides out of the groove 221. Therefore, when the plug 1 overcomes the damping force and disengages from the female socket 2, the damping force between the spring piece 2 164 and the wavy protrusion and the groove 221, as well as the elastic force of the elastic rope, buffers the plug 1, thereby reducing the speed of the plug 1 when it is disengaged from the female socket 2, and preventing the plug 1 from being thrown onto other devices at a large speed to cause damage to the plug 1 or the device;

[0036] When it is necessary to disconnect during detection, the sliding sleeve 14 is pinched to separate the plug 1 from the female socket 2. The sliding sleeve 14 moves to the left relative to the shell 11 so that the toggle shaft 168 pushes the paddle 167. The paddle 167 toggles the slider 166 to separate the hooking parts on the slider 166 and the pin 162 from each other. When the pin 13 is separated from the socket 21, the spring 164 enters the groove 221, so that the plug 1 and the female socket 2 are not completely separated and the conductive connection between the two is disconnected. Therefore, it is avoided that the plug 1 is found again after detection and repositioned to insert into the female socket 2.

[0037] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
