Connector and connector assembly

Abstract

This invention provides a connector and a connector assembly. The connector includes a connector body and a knob. The connector body has a mounting hole and two locking rods. When the connector mates with a mating connector, the two locking rods swing to an engaged position to engage two latches on the mating connector. When the locking rods swing to an unengaged position, they disengage from the corresponding latches. The knob is rotatably disposed within the mounting hole and has a locking portion located between the two latches. The knob is configured to rotate between a locked position and an unlocked position. The knob controls the locking portion to rotatably abut against at least one locking rod. Thus, the connector simultaneously locks the two locking rods through the knob, which helps improve the reliability of the connection when the connector is mated and can also lock the locking rods to prevent incorrect connector mating when the connector is not mated.

[0005] In some implementations, the locking part presses down on both locking levers simultaneously when the knob is in the locked position, and disengages from both locking levers simultaneously when the knob is in the unlocked position.

[0006] In some embodiments, the knob further includes: a main body portion that matches and is rotatably disposed within the mounting hole, and a locking portion provided at one end of the main body portion facing the locking rod; and a drive portion disposed at one end of the main body portion away from the locking portion.

[0007] In some embodiments, an annular boss is provided on the inner wall of the mounting hole; an annular groove is provided on the side of the main body, and the annular groove and the annular boss are matched to accommodate the annular boss.

[0008] In some embodiments, the annular grooves are arranged at 330° to form a first gap; the annular bosses are arranged at 240° to form a second gap.

[0009] In some embodiments, a stop portion is formed at the first gap in the main body, and the stop portion moves within the second gap.

[0010] In some embodiments, an arc-shaped boss is formed at the middle position of the second gap, and the arc-shaped boss is arranged at 60°.

[0011] In some implementations, a first slope is provided at each end of the arc-shaped boss.

[0012] In some implementations, the two sides of the arc-shaped boss are each formed as a second slope.

[0013] In some embodiments, a first inclined surface is formed on the annular boss; a second inclined surface is formed in the annular groove, and the second inclined surface matches the first inclined surface.

[0014] In some embodiments, both the driving part and the locking part are configured as rod-shaped structures, and the driving part and the locking part are arranged parallel to each other.

[0015] In some embodiments, the knob further includes a connecting portion, which is connected to both the main body and the locking portion.

[0016] In some embodiments, the locking bar includes: a fulcrum portion, one end of which is connected to the locking bar and the other end of which protrudes toward the connector body; a rod body portion, which is configured as a rod-shaped structure, connected to the fulcrum portion and divided into a first rod body and a second rod body by the fulcrum portion; and a fastening portion, which is disposed at the end of the first rod body and configured to fasten with the latch.

[0017] In some implementations, the length of the first rod is greater than that of the second rod.

[0018] In some embodiments, the end of the fastening portion facing the mating connector has a third bevel.

[0019] In some embodiments, the end of the first rod is chamfered.

[0020] In some embodiments, the end of the second rod has a protrusion.

[0021] In some implementations, the connector body has a perforation to expose the locking rod.

[0022] In some implementations, a notch is formed at the leak.

[0023] Secondly, embodiments of the present invention also provide a connector assembly, the connector assembly including: a connector as described in the first aspect; and a mating connector, the mating connector having two latches formed on its protrusions, the two latches engaging two locking rods when the mating connector is mated with the connector.

[0024] In some implementations, the end of the latch facing the connector has a fourth bevel.

When the connector mates with a mating connector, the two locking rods swing to an engaged position to engage two latches on the mating connector. When the locking rods swing to an unengaged position, they disengage from the corresponding latches. The knob is rotatably disposed within the mounting hole and has a locking portion located between the two latches. The knob is configured to rotate between a locked position and an unlocked position. The knob controls the locking portion to rotatably abut against at least one locking rod. Thus, the connector simultaneously locks the two locking rods through the knob, which not only helps improve the reliability of the connection when the connector is mated, but also locks the locking rods to prevent incorrect connector mating when the connector is not mated.

Implementation

[0027] The present application is described below based on embodiments, but it is not limited to these embodiments. In the detailed description of the present application below, certain specific details are described in detail. Those skilled in the art to which this application pertains will fully understand the present application without these details. To avoid obscuring the substance of the present application, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0028] Furthermore, those skilled in the art to which this application pertains should understand that the drawings provided herein are for illustrative purposes and are not necessarily drawn to scale.

[0029] Unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art to which this application pertains can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] For ease of explanation, spatially related terms such as "inside," "outside," "below," "below," "lower part," "above," and "upper part," etc., are used herein to describe the relationship between one element or feature illustrated in the figure and another element or feature. It will be understood that spatially related terms may be intended to encompass different orientations of the device in use or operation besides those depicted in the figure.

Thus, the exemplified term "below" can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially related descriptive terms used herein should be interpreted accordingly.

[0031] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0032] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0033] Figure 1 is a structural schematic diagram of the connector provided in an embodiment of the present invention, and Figure 2 is a structural schematic diagram of the connector provided in another perspective of an embodiment of the present invention. Referring to Figures 1 and 2, connector A includes a connector body 1 and a knob 2. Figure 3 is a structural schematic diagram of the connector body provided in an embodiment of the present invention. As shown in Figure 3, the connector body 1 is provided with a mounting hole 11 and two locking rods 12. Specifically, the locking rods 12 are configured to swing between a latching position and a release position. It should be noted that when the locking rods 12 are in the latching position, the two locking rods 12 are in their initial state and parallel to each other. Correspondingly, when the locking rods 12 are in the release position, the two locking rods 12 deflect towards each other. Figure 4 is a structural schematic diagram of the connector provided in an embodiment of the present invention after it is mated with a mating connector, and Figure 5 is a structural schematic diagram of the mating connector provided in an embodiment of the present invention. Referring to Figures 1 to 5, when connector A is mated with mating connector B, the two locking rods 12 are in the latching position to latch the two latches B1 on mating connector B. On the other hand, when the locking rods 12 are in the release position, they separate from the corresponding latches B1. It should be noted that the separation of the locking rod 12 from the latch B1 means that the locking rod 12 can move relative to the latch B1 in the insertion direction of the connector A.

[0034] Figure 6 is a structural schematic diagram of the knob provided in an embodiment of the present invention. As shown in Figure 6, the knob 2 has a locking part 21. Figure 7 is a positional schematic diagram of the connector and mating connector before docking provided in an embodiment of the present invention. Figure 8 is a cross-sectional schematic diagram of the connector and mating connector before docking provided in an embodiment of the present invention. Figure 9 is a cross-sectional schematic diagram of the connector and mating connector after docking provided in an embodiment of the present invention. Figure 10 is a positional schematic diagram of the knob in the locked position provided in an embodiment of the present invention. Figure 11 is a cross-sectional schematic diagram of the knob in the locked position provided in an embodiment of the present invention. Referring to Figures 7 to 11, the knob 2 is rotatably disposed within the mounting hole 11 and configured to rotate between the locked position and the unlocked position. Further, the locking part 21 is located between the two locking rods 12. Furthermore, when the knob 2 is rotated to the locked position, it drives the locking part 21 to rotate into place so as to simultaneously press the two locking rods 12. On the other hand, when the knob 2 is rotated to the unlocked position, it drives the locking part 21 to rotate into place so as to simultaneously disengage from the two locking rods 12. It is easy to understand that when the two locking rods 12 are engaged with the two latches B1, both ends of the locking part 21 act synchronously on the two locking rods 12. That is, even if the two locking rods 12 tend to deflect towards the unlocking position, they will interact with each other while being subjected to the force of the locking part 21, making the entire locking structure self-locking, thereby helping to improve the reliability of the connection when connector A is mated with mating connector B. On the other hand, when connector A does not need to be mated with mating connector B, the knob 2 rotates to make the locking part 21 press the two locking rods 12 synchronously, so that the locking rods 12 cannot deflect to the unlocking position and therefore cannot engage with latches B1, thereby preventing connector A from being fully inserted with mating connector B.

[0035] As an optional implementation, only one locking lever 12 is provided. That is, the reliability of the connection between connector A and mating connector B can be ensured by using knob 2 to engage one locking lever 12 with one latch B1.

[0036] As shown in Figure 6, in one embodiment, the knob 2 further includes a main body 22 and a drive part 23. Specifically, the main body 22 is matched with and rotatably disposed within the mounting hole 11, and the locking part 21 is disposed at the end of the main body 22 facing the locking rod 12. It should be noted that the mounting hole 11 is a circular hole, and the main body 22 is configured as a cylindrical structure, which facilitates the rotation of the knob 2 within the mounting hole 11. Furthermore, the drive part 23 is disposed at the end of the main body 22 opposite to the locking part 21. It is easy to understand that when the operator rotates the drive part 23, the locking part 21 will rotate through the main body 22, so that the locking part 21 presses against or disengages from the locking rod 12.

[0037] Figure 12 is a partially enlarged schematic diagram of the mounting hole provided in an embodiment of the present invention. As shown in Figure 12, in one embodiment, an annular boss 111 is provided on the inner sidewall of the mounting hole 11. Correspondingly, Figure 13 is a cross-sectional schematic diagram of the knob in the unlocked position provided in an embodiment of the present invention. As shown in Figures 6, 12, and 13, an annular groove 221 is provided on the side of the main body 22, and the annular groove 221 matches the annular boss 111 to accommodate the annular boss 111. It is easy to understand that the annular boss 111 is located in the annular groove 221, thereby realizing the installation of the knob 2 in the mounting hole 11. Further, when the knob 2 rotates between the locked position and the unlocked position, the annular boss 111 moves relative to the annular groove 221.

[0038] As shown in Figure 6, in one embodiment, the annular groove 221 is arranged at 330° to form a first gap 222. On the other hand, as shown in Figure 12, the annular boss 111 is arranged at 240° to form a second gap 112. It is readily understood that when the knob 2 is rotated between the locked and unlocked positions, the annular boss 111 has a 90° range of motion within the annular groove 221. That is, rotating the knob 2 90° from the locked position reaches the unlocked position. Correspondingly, rotating the knob 2 90° from the unlocked position reaches the locked position. Thus, the locking part 21, through a 90° rotation, can ensure complete disengagement from the locking lever 12 or effective pressing of the locking lever 12.

[0039] As shown in Figure 6, in one embodiment, the main body 22 has a stop 223 formed at the first gap 222. It is readily understood that the first gap 222, i.e., the stop 223, is arranged at a 30° angle. Correspondingly, the second gap 112 is arranged at a 120° angle. Furthermore, the stop 223 moves within the second gap 112. Thus, when the knob 2 is rotated to the locked or unlocked position, the stop 223 abuts against the end of the annular boss 111, thereby ensuring that the knob 2 is rotated to the correct position and limiting the rotation of the knob 2.

[0040] As shown in Figure 12, in one embodiment, an arc-shaped boss 113 is formed at the middle position of the second gap 112. Further, the arc-shaped boss 113 is arranged at 60° intervals. It is easily understood that when the knob 2 is in the locked or unlocked position, the stop 223 does not contact the arc-shaped boss 113, while the arc-shaped boss 113 can restrict the stop 223 to maintain the fixed position of the knob 2. It should be noted that the degree of arching of the arc-shaped boss 113 is relatively small. Therefore, when the knob 2 is rotated from the locked position to the unlocked position, or from the unlocked position to the locked position, the stop 223 presses against the arc-shaped boss 113 to rotate, thus allowing the resistance exerted by the arc-shaped boss 113 on the knob 2 to be fed back to the operator, providing a tactile feedback of rotation.

[0041] As shown in Figure 12, in one embodiment, a first slope 1131 is provided at each end of the arc-shaped boss 113. Thus, when the knob 2 is rotated from the locked position to the unlocked position, or from the unlocked position to the locked position, the stop part 223 can slide along the first slope 1131 onto the arc-shaped boss 113, thereby reducing the resistance when the knob 2 is rotated.

[0042] As shown in Figure 12, in one embodiment, the two sides of the arc-shaped boss 113 are respectively formed as a second slope 1132. Therefore, when the knob 2 is rotated and the stop part 223 slides on the arc-shaped boss 113, the contact area between the stop part 223 and the arc-shaped boss 113 is small, which helps to improve the smoothness of the knob 2 rotation.

[0043] As shown in Figure 12, in one embodiment, a first inclined surface 1111 is formed on the annular boss 111. Correspondingly, a second inclined surface 2211 is formed in the annular groove 221. It is readily understood that the second inclined surface 2211 matches the first inclined surface 1111. Thus, the inclined surface contact between the annular boss 111 and the annular groove 221 helps to improve the smoothness of the rotation of the knob 2.

[0044] As shown in Figure 6, in one embodiment, both the drive unit 23 and the locking unit 21 are configured as rod-shaped structures. On the one hand, the rod-shaped drive unit 23 allows the operator to easily and conveniently turn the rotary knob 2. On the other hand, the rod-shaped locking unit 21 helps to simultaneously press or release the locking lever 12. Furthermore, the drive unit 23 and the locking unit 21 are arranged parallel to each other. Thus, when the operator turns the knob 2 through the drive unit 23, the current position of the locking unit 21 can be clearly seen.

[0045] As shown in Figure 6, in one embodiment, the knob 2 further includes a connecting portion 24. Specifically, the connecting portion 24 is connected to both the main body 22 and the locking portion 21. It should be noted that the knob 2 can adjust the distance between the locking portion 21 and the main body 22 through the connecting portion 24, thereby ensuring that the locking portion 21 and the locking lever 12 are kept in the same plane, and thus ensuring that the locking portion 21 can press the locking lever 12.

[0046] Referring to Figures 8, 9, and 11, in one embodiment, the locking lever 12 includes a fulcrum portion 121, a lever body portion 122, and a fastening portion 123. Specifically, one end of the fulcrum portion 121 is connected to the locking lever, and the other end protrudes toward the connector body 1. Further, the lever body portion 122 is configured as a rod-shaped structure and connected to the fulcrum portion 121. It should be noted that the lever body portion 122 is divided into a first lever body 1221 and a second lever body 1222 by the fulcrum portion 121. Furthermore, the fastening portion 123 is disposed at the end of the first lever body 1221 and configured to fasten with the latch B1. Thus, the lever body portion 122 can form a lever structure based on the fulcrum portion 121, thereby enabling swinging between the fastening position and the unlocking position. Optionally, the locking lever 12 has sufficient flexibility at the position of the fulcrum portion 121. It should be noted that the fastening portion 123 protrudes from the first lever body 1221 toward the direction away from the locking portion 21.

[0047] Referring to Figures 8, 9, and 11, in one embodiment, the length of the first rod 1221 is greater than that of the second rod 1222. Therefore, when the end of the first rod 1221 is subjected to the force of the latch B1, causing the locking rod 12 to deflect, the locking rod 12 only requires a small force to swing to the unlocked position for subsequent engagement with the latch B1. On the other hand, when the operator applies a force to the second rod 1222, causing the locking rod to deflect, the force applied to the locking rod 12 must be sufficiently large to help ensure that the locking rod 12 does not easily separate from the latch B1, thereby helping to ensure the reliability of the connection between connector A and mating connector B. Optionally, the length of the first rod 1221 is set to be twice that of the second rod 1222.

[0048] Referring to Figures 9 and 11, in one embodiment, the fastening part 123 has a third slope 1231 at the end facing the mating connector B. Therefore, during the docking process between connector A and mating connector B, the third slope 1231 of the fastening part 123 first contacts the latch B1, allowing the fastening part 123 to deflect under the force of the latch B1 and drive the locking rod 12 to deflect towards the unfastening position, so that the locking rod 12 and the latch B1 can automatically engage.

[0049] Referring to Figures 9 and 11, in one embodiment, the end of the first rod 1221 is provided with a chamfer 12211. It should be noted that the chamfer 12211 can not only prevent collision damage between the locking rod 12 and the latch B1, but also guide the movement of the locking rod 12.

[0050] Referring to Figures 9 and 11, in one embodiment, the end of the second rod 1222 has a protrusion 12221. It should be noted that when the operator opens the locking lever 12, a force needs to be applied to the second rod 1222 to deflect the locking lever 12. The protrusion 12221 serves as a force-bearing point for the locking lever 12 to ensure smooth operation by the operator. Furthermore, the protrusion 12221 also provides a certain degree of stopping power.

[0051] Referring to Figures 1 and 3, in one embodiment, the connector body 1 has a recessed mating groove 13 on the side facing the mating connector B. It should be noted that the mating groove 13 matches the mating connector B, allowing connector A to be adapted and mated with the mating connector B. Further, the sidewall of the mating groove 13 is offset outward to form an expansion groove 131. It should be noted that the expansion groove 131 is used to accommodate the locking rod 12. It is readily understood that the locking part 21 extends into the expansion groove 131. Thus, the structure of connector A is more compact, the locking part 21 and the locking rod 12 do not occupy additional external space, and the assembly of connector A and mating connector B is more secure.

[0052] As shown in Figure 2, in one embodiment, the bottom of the expansion groove 131 is hollowed out to form a perforation 132. Thus, the locking rod 12 can be exposed through the perforation 132. This allows the operator to easily apply force to the locking rod 12 through the perforation 132, thereby opening the locking rod 12. Furthermore, in one embodiment, a notch 133 is formed at the perforation 132. It is readily understood that providing the notch 133 provides the operator with greater operating space, allowing the operator to more easily apply force to the locking rod 12 using tools or other means.

[0053] This invention also provides a connector assembly, which includes a connector A and a mating connector B. Exemplarily, connector A is a plug, and mating connector B is a socket. The structure of connector A is as described above and will not be repeated here. On the other hand, two latches B1 are protruded on mating connector B. Further, when mating connector B mates with connector A, the two latches B1 engage with two locking rods 12. Thus, connector A simultaneously locks the two locking rods 12 via a knob, which not only improves the reliability of the connection with mating connector B when connector A is mated, but also locks the locking rods 12 to prevent incorrect mating of connector A when connector A is not mated.

[0054] As shown in Figure 5, in one embodiment, the end of the latch B1 facing the connector A is provided with a fourth slope B11. Thus, when the connector A mates with the mating connector B, the latching part 123 of the locking rod 12 can move along the fourth slope B11, thereby causing the locking rod 12 to deflect.

[0055] This invention provides a connector and a connector assembly. The connector includes a connector body and a knob. The connector body has a mounting hole and two locking rods. When the connector mates with a mating connector, the two locking rods swing to the engaging position to engage two latches on the mating connector. When the locking rods swing to the disengaged position, they disengage from the corresponding latches. The knob is rotatably disposed within the mounting hole and has a locking part located between the two latches. When the knob is rotated to the locked position, the locking part simultaneously presses down on the two locking rods. When the knob is rotated to the unlocked position, the locking part simultaneously disengages from the two locking rods. Thus, the connector simultaneously locks the two locking rods through the knob, which not only helps improve the reliability of the connection when the connector is mated, but also locks the locking rods to prevent incorrect connector mating when the connector is not mated.

Various modifications and variations can be made to this application by those skilled in the art.
