Description

Technical Field

[0001] The present invention relates to connector technology, and in particular to an electric connector plug and a connector assembly. Background Art

[0002] With the development of communication technology, connectors are increasingly used and in greater demand. The connector plug consists of a housing and a connecting nut that fits over the housing. A sealing gasket is located within the housing. When a cable is inserted through the housing, the nut rotates and compresses the sealing gasket, ensuring a tight seal between the cable and the housing.

[0003] However, during actual use, the nut can gradually loosen due to product vibration or cable sway, resulting in reduced compression of the plug housing's gasket and a potential sealing issue. Therefore, regular maintenance and inspection of the connector plug is generally required to ensure the nut is not loose. However, frequent inspections and repairs waste time, labor costs, and are inefficient. Summary of the Invention

[0015] In a possible embodiment, a fixed shaft is provided on the plug housing, and the locking member is provided with a socket, and the socket is sleeved on the fixed shaft so that the locking member can rotate relative to the plug housing;

[0016] The locking member is provided with a concave guide groove on the side of the plug housing, and the guide groove is configured to guide the socket to be inserted into the fixed shaft. The groove depth and groove width of the guide groove gradually decrease along the side edge of the locking member toward the socket.

[0017] In a possible embodiment, at least one blocking portion is provided on the plug housing;

[0018] At least one matching portion is provided on a side of the locking member facing the plug housing. When the locking member rotates, the blocking portion and the matching portion form a detachable limiting fit to maintain the locking member in a non-rotating state.

[0041] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0042] As mentioned in the background technology, the nut of the connector is easily affected by the vibration of the product or the swing of the cable, and gradually retreats and loosens. For this reason, when the connector plug uses threaded sealing, in order to prevent the nut from loosening due to vibration, thereby affecting the sealing effect, a spring washer or a disc washer is generally placed between the nut and the plug housing. When the nut is tightened, the washer is flattened, generating additional elastic force to resist loosening caused by vibration.

[0043] However, the service life of spring washers or disc washers is relatively short, especially in working scenarios with frequent vibrations. The spring washers may have a limited service life and cannot effectively prevent the nuts from loosening. Operators usually need to conduct regular inspections and maintenance, which wastes time and labor costs and is inefficient.

[0044] Based on the above related description, an electrical connector plug is provided in one or more embodiments of the present application, which is described below with reference to the accompanying drawings.

[0045] like Figures 1 to 5 As shown, in an embodiment of the present application, an electrical connector plug is provided for connecting a cable 600 , including a plug housing 100 , a fastener 200 , a sealing member 300 and a locking member 400 .

[0046] Among them, the fastener 200 is rotatably connected to the plug housing 100; the sealing member 300 is arranged between the fastener 200 and the plug housing 100, and the sealing member 300 is configured to shrink and compress the cable 600 as the fastener 200 rotates, so as to seal the plug housing 100 together with the cable 600; the locking member 400 is connected to the plug housing 100, and the locking member 400 is configured to cooperate with the fastener 200 to form a locked state to prevent the circumferential rotation of the fastener 200.

[0047] From the above description, it can be seen that the electrical connector plug in the embodiment of the present application is rotatably connected to the plug housing 100 by the fastener 200, and the seal 300 is pressed into the plug housing 100 by the fastener 200. The seal 300 and the outer surface of the cable 600 jointly seal the plug housing 100. Since the plug housing 100 is connected to a locking member 400, when the locking member 400 cooperates with the fastener 200 to form a locked state, the locking member 400 can lock the rotation of the fastener 200, preventing the fastener 200 from retreating and loosening due to the vibration of the product or the swinging of the cable 600, thereby effectively ensuring the sealing effect of the seal 300 in the plug housing 100.

[0048] In the above embodiment, the connection method between the electrical connector plug and the cable 600 can be set with reference to relevant technologies, such as crimping or plug-in connection. For example, there is a certain space inside the plug housing 100, and the cable 600 is directly inserted into the corresponding position inside the plug housing 100 through a pre-crimped connector (such as a piercing connector). There is a contact component inside the plug housing 100, and the structure of the contact component is used to pierce the insulation layer of the cable 600 and form electrical contact. Here, this application only provides an example to illustrate this.

[0049] In some embodiments, the locking member 400 is rotatably connected to the plug housing 100; the locking member 400 includes a snap-fit ​​portion 410 extending toward the fastener 200, and the snap-fit ​​portion 410 is configured to approach or move away from the fastener 200 as the locking member 400 rotates. When the snap-fit ​​portion 410 approaches the fastener 200, it can engage and snap-fit ​​with the fastener 200 to prevent the circumferential rotation of the fastener 200.

[0050] For example, Figures 1 to 4 As shown, in the embodiment of the present application, at least part of the cross-section of the plug housing 100 has an edge 110, and the locking member 400 is provided with a limit frame 420 for engaging with the edge 110. When the engaging portion 410 engages with the engaging tooth 210, the limit frame 420 engages with the edge 110.

[0051] Here, illustratively, the locking member 400 can be made entirely of high-strength engineering plastic material or metal material. The locking member 400 itself has a certain rigidity, thereby ensuring a limiting effect on the fastener 200 .

[0052] The cross-section of the plug housing 100 is rectangular, the cross-section of the fastener 200 is circular, and the limiting frame 420 is a rectangular frame adapted to the shape of the plug housing 100. The cross-section of the limiting frame 420 is in the shape of a "door" as shown in the figure. Figure 1 In the figure, when the locking member 400 is connected to the fastener 200, the M direction indicated by the arrow is the rotation direction of the locking member 400 relative to the plug housing 100. When the locking member 400 rotates on the plug housing 100, the limit frame 420 engages and snaps into the edge 110 of the plug housing 100 along with the rotation. On the one hand, this arrangement can enhance the limiting constraint effect between the locking member 400 and the plug housing 100, ensuring that the snap-on portion 410 on the locking member 400 will not be forcibly rotated by the fastener 200. On the other hand, when the limit frame 420 engages with the edge 110 of the plug housing 100, the locking member 400 is attached to the plug housing 100, reducing the space occupied by the locking member 400 on the plug housing 100, thereby helping to improve assembly flexibility.

[0053] As an alternative embodiment, the limit frame 420 is bent so that its cross-section is "L"-shaped. The bent portion of the limit frame 420 corresponds to the edge 110 of the plug housing 100. After the bent portion of the limit frame 420 is engaged with the edge 110, the limiting effect of the locking member 400 and the plug housing 100 can also be enhanced.

[0054] Furthermore, if Figure 3 and Figure 4 As shown, in the embodiment of the present application, the side wall of the plug housing 100 is provided with at least one first elastic clamp 120, and the limiting frame 420 is provided with a protruding second elastic clamp 430. When the clamping portion 410 is engaged with the clamping tooth 210, the first elastic clamp 120 and the second elastic clamp 430 form a detachable clamping connection.

[0055] Specifically, the first elastic clamp 120 has a wedge-shaped first clamping end 121, and the second elastic clamp 430 includes a spring piece 432 arranged on the limit frame 420 and a second clamping end 431 arranged opposite to the spring piece 432. One side end of the spring piece 432 is connected to the limit frame 420, and the other side end is separated from the limit frame 420. The second clamping end 431 is located on the opposite side of the connection side end of the spring piece 432 and the limit frame 420. During the rotation of the limit frame 420 relative to the plug housing 100, the second clamping end 431 on the limit frame 420 abuts against the first clamping end 121, causing the first elastic clamp 120 to deform and give way. As the rotation action further advances, the second clamping end 431 is hooked and connected with the first clamping end 121, preventing the limit frame 420 from separating from the plug housing 100.

[0056] When it is necessary to release the connection between the limit frame 420 and the plug housing 100, manually press the spring piece 432, and the spring piece 432 pushes the first elastic clamp 120 to sink, and the first clamping end 121 on the first elastic clamp 120 sinks synchronously to make way, releasing the hook engagement state between the first clamping end 121 and the second clamping end 431. Maintain this state and pull out the limit frame 420.

[0057] By providing the first elastic clamp 120 and the second elastic clamp 430, a detachable hook connection can be formed between the locking member 400 and the plug housing 100, so that the clamping portion 410 of the locking member 400 always limits the clamping fastener 200, preventing the clamping portion 410 of the locking member 400 from being separated from the fastener 200 due to vibration or swinging of the cable 600.

[0058] In some embodiments, a plurality of latching teeth 210 are provided at intervals on the outer peripheral wall of the fastener 200 , and the latching portion 410 is engaged with the latching teeth 210 .

[0059] The above-mentioned fastener 200 is threadedly connected to the plug housing 100, that is, the end of the plug housing 100 is provided with an external thread section, and the fastener 200 has an internal thread section. The internal thread section and the external thread section are threadedly connected, and the teeth 210 on the fastener 200 protrude outward along the radial direction of the fastener 200. The teeth 210 on the fastener 200 can be integrally formed by stamping, or, when the fastener 200 on the connector has a high adaptation accuracy, the teeth 210 can be directly welded on the circumference of the fastener 200. There is no absolute limitation on this.

[0060] The engaging portion 410 is disposed on the inner side of the end of the limit frame 420 facing the fastener 200. The limit frame 420 has an arc-shaped concave transition surface that matches the outer peripheral wall of the fastener 200. The engaging portion 410 is disposed on this transition surface. The engaging portion 410 is specifically a slot that engages with the latching teeth 210. When the limit frame 420 is rotated to engage with the plug housing 100, the engaging portion 410 on the limit frame 420 also engages with the latching teeth 210, thereby utilizing the locking member 400 to provide a mechanical anti-loosening effect. The interlocking engagement between the latching teeth 210 and the engaging portion 410 not only improves the connection stability between the fastener 200 and the plug housing 100, but also facilitates inspection and maintenance by operators. When the fastener 200 needs to be removed, the locking member 400 only needs to be rotated to disengage the fastener 200. Disassembling the fastener 200 also facilitates replacement of the cable 600 or repair of internal components of the plug housing 100.

[0061] Reference Figure 3 and Figure 5 In some embodiments, the plug housing 100 is provided with a fixed shaft 140, and the locking member 400 is provided with a socket 470. The socket 470 is sleeved on the fixed shaft 140 to enable the locking member 400 to rotate relative to the plug housing 100. Here, the locking member 400 is further provided with a concave guide groove 460 on the side facing the plug housing 100. The guide groove 460 is configured to guide the socket 470 to be sleeved on the fixed shaft 140. The groove depth and groove width of the guide groove 460 gradually decrease along the side edge of the locking member 400 toward the socket 470.

[0062] In the above embodiment, the guide groove 460 is an approximately trapezoidal groove. The long side direction of the guide groove 460 is located at the side end of the locking member 400 and is flush with the side end of the locking member 400. The short side direction of the guide groove 460 is close to and gradually transitions to the insertion hole 470. The groove depth of the guide groove 460 is the largest in the direction of the side edge and the smallest at the position of the insertion hole 470. Here, the direction of the side edge of the locking member 400 toward the insertion hole 470 refers to the insertion direction when the locking member 400 is installed in the plug housing 100, that is, Figure 6 In the N direction pointed by the middle arrow, when the locking piece 400 is installed on the plug housing 100, due to the large groove depth of the guide groove 460, the locking piece 400 can gradually move to the position of the fixed shaft 140 with a small degree of deformation until the socket 470 is socketed and connected with the fixed shaft 140. The guide groove 460 can reduce the blocking interference force between the locking piece 400 and the plug housing 100 during installation, thereby facilitating the assembly of the locking piece 400.

[0063] It should be noted that in the electrical connector plug of the embodiment of the present application, a fixed shaft 140 is provided on opposite sides of the plug housing 100, and two receptacles 470 are provided on the locking member 400, with the fixed shafts 140 correspondingly connected to the receptacles 470. That is, the receptacles 470 are located on opposite sides of the limiting frame 420, each of which is provided with a second elastic clamp 430. The plug housing 100 is correspondingly provided with two first elastic clamps 120. This arrangement helps ensure the stability of the connection of the locking member 400 to the plug housing 100.

[0064] Reference Figure 6 In some embodiments, the electrical connector plug further includes at least one blocking portion 130 and at least one mating portion 440. The blocking portion 130 is disposed on the plug housing 100, and the mating portion 440 is disposed on the side of the locking member 400 facing the plug housing 100. When the locking member 400 rotates, the blocking portion 130 and the mating portion 440 form a detachable limiting fit to maintain the locking member 400 in a non-rotating state.

[0065] Specifically, the blocking portion 130 is a spherical protrusion provided on the plug housing 100, and the mating portion 440 is a spherical groove provided on the locking member 400; wherein, the locking member 400 is provided with an inwardly concave positioning groove 450 on the side facing the plug housing 100, and the positioning groove 450 is configured to place the locking member 400 in an open position.

[0066] In the above embodiment, Figure 1 and Figure 2 As shown, when the locking member 400 is engaged with the fastener 200 and opened, the blocking portion 130 engages with the positioning groove 450 of the locking member 400. When it is necessary to unlock the locked state of the locking member 400 and the fastener 200, the blocking portion 130 and the matching portion 440 form a simple limit fit, at which point the locking member 400 is unlocked and remains in this position without displacement. The provision of the blocking portion 130 and the matching portion 440 allows the locking member 400 to remain in a stationary state without rotation when not engaged with the fastener 200, facilitating maintenance work by operators.

[0067] It should be noted that the positioning groove 450 can also be a spherical groove, and the blocking portion 130 forms a limited fit with the matching portion 440 along the rotation path of the locking member 400. This arrangement can minimize the interference between the blocking portion 130 and the locking member 400, making the rotation of the locking member 400 smoother. Of course, the limited fit between the blocking portion 130 and the matching portion 440 can be released by external force, that is, the external force can overcome the limiting effect of the blocking portion 130 and the matching portion 440, driving the locking member 400 to continue rotating.

[0068] Of course, in the embodiment of the present application, a plurality of blocking portions 130 may be provided on the plug housing 100, and a plurality of mating portions 440 may be provided on the locking member 400, and the blocking portions 130 and the mating portions 440 are arranged in a one-to-one correspondence; in addition, when the blocking portion 130 is a spherical protrusion and the mating portion 440 is a spherical groove, the deeper the depression depth of the mating portion 440, the greater the degree of deformation of the locking member 400, and the greater the external force required for the locking member 400 to switch from a stationary state to a movable rotational state. Therefore, the sizes of the blocking portion 130 and the mating portion 440 can be set according to the actual usage scenario.

[0069] As an alternative embodiment, the locking member 400 is a latch that is detachably connected to the plug housing 100. When the locking member 400 is plugged into the plug housing 100, the locking member 400 penetrates the fastener 200 in the radial direction of the fastener 200 to prevent the fastener 200 from rotating in the circumferential direction. Here, the connection method between the locking member 400 and the plug housing 100 is described as an example in the embodiments of the present application.

[0070] Please refer to Figure 5 , Figure 5 In the figure, the seal 300 is a cylindrical seal, which is made of rubber material or silicone rubber material. A portion of the seal 300 is inserted into the plug housing 100, and the other portion is exposed outside the plug housing 100. The outer wall of the seal 300 is constructed with a lip 310, and the seal 300 is overlapped on the plug housing 100 via the lip 310. When the fastener 200 is tightened, the fastener 200 presses the exposed portion of the seal 300 toward the bottom of the plug housing 100, forcing the seal 300 to further deform and fit tightly against the plug housing 100 and the cable 600. The pressing force of the fastener 200 causes the seal 300 to completely block the external environment and the internal space of the plug housing 100, preventing moisture, dust and other contaminants from entering the plug housing 100.

[0071] Compared with the direct filling and sealing method, the fastener 200 thread and the seal 300 seal can facilitate the disassembly and assembly of the cable 600, and can also facilitate the replacement of the seal 300 after a period of use without replacing the entire connector, which is beneficial to improving the service life and use effect of the electrical connector.

[0072] In the above embodiment, the exposed portion of the seal 300 has a plurality of notches 320. As the fastener 200 is tightened, the notches 320 are deformed and contracted by external force to compress the cable 600, thereby facilitating the compression deformation and sealing of the seal 300 and ensuring the sealing effect of the seal 300 on the plug housing 100.

[0073] The present application also provides a connector assembly including the electrical connector plug of any of the above embodiments. Since the connector assembly of the present application includes the electrical connector plug of any of the above embodiments, it has all the advantages of the electrical connector plug.

[0074] like Figure 1 As shown, the connector assembly also includes a socket 500, which is used to be plugged into and connected to the electrical connector plug. The side wall of the socket 500 is provided with a protruding first limiting portion 510, and the end of the locking member 400 away from the fastener 200 is provided with a second limiting portion 480. When the clamping portion is rotated to be clamped with the fastener 200, the first limiting portion 510 and the second limiting portion 480 are hooked and connected to prevent the electrical connector plug from being separated from the socket 500.

[0075] Here, for example, the first limiting portion 510 is a protrusion provided on the socket 500, and the second limiting portion 480 is a hook provided on the locking member 400. When the locking portion rotates to engage with the fastener 200, the hook is engaged with the protrusion. At this time, the socket 500 is locked by the locking member 400 and cannot be axially separated from the electrical connector plug. Through this arrangement, the locking member 400 on the electrical connector plug can maintain the rotational limit constraint on the fastener 200, and at the same time, the locking member 400 also enhances the plugging and unplugging effect between the socket 500 and the electrical connector plug, preventing the electrical connector plug from accidentally detaching from the socket 500.

[0076] Here, it should be noted that the socket 500 can be installed on a fixed device or on a movable device. For example, the socket 500 is installed on an interface board of a server rack, instrument or production equipment, which is not absolutely limited in the embodiments of this application.

The scope of the present application is limited only by the appended claims.
