[0042] See Figure 1 As shown, an embodiment of the present application provides a cable connector 100 that can be used for conductive connections between various devices or cables 200 , thereby improving the assembly strength and working stability of the cable connector 100 .

[0043] Continue reading Figure 2 、 Figure 3 and Figure 4 Specifically, the cable connector 100 includes a plug 110, a housing 120, and a cap 130. The plug 110 is used to route the cable 200 and mate with an external connector to establish a circuit connection for the cable 200. The housing 120 is located at the end of the plug 110 away from the external connector and is used to protect the plug 110 and the cable 200. The cap 130 is movably connected between the plug 110 and the housing 120 to strengthen the connection between the plug 110 and the housing 120.

[0044] Illustratively, the plug 110 has a plug end 111 that can be plugged into and mated with an external connector. It is understood that the plug end 111 can be a male or female connector, and the external connector can be adaptively provided with a female or male connector to facilitate circuit connection between the plug 110 and the external connector.

[0045] In this embodiment, the plug 110 is made of insulating material, and the plug end 111 is a male connector. Plug 110 is internally provided with multiple through-holes 112 extending axially therethrough. Each through-hole 112 is fitted with a conductive metal post, and each post has a receptacle for inserting a female pin from an external connector. One end of the cable 200 is connected to the post, and the other end extends away from the plug 110.

[0046] Furthermore, the housing 120 is a hollow cylindrical structure, and a receiving cavity 121 is provided therein, extending axially through both ends of the housing 120. Thus, the end of the plug 110 opposite the plug end 111 is inserted into the receiving cavity 121, and the end of the cable 200 away from the plug 110 extends from the other end of the receiving cavity 121, completing the assembly of the plug 110 and the housing 120.

[0047] Furthermore, the cap body 130 is also a cylindrical structure with two through ends. One end is sleeved onto the plug 110, and the other end is threadedly engaged with the housing 120. Specifically, the interior of the cap body 130 is provided with a spiral internal thread structure, and the outer side of the housing 120 that is sleeved with the plug 110 is correspondingly provided with an external thread structure. Therefore, after the plug 110 is inserted into the housing 120, the cap body 130 can be tightened to fix the plug 110 to the housing 120, thereby enhancing the assembly strength of the plug 110 and facilitating assembly and disassembly.

[0048] Continue reading Figure 4 and Figure 5 As shown, in some embodiments, a plurality of bosses 115 are circumferentially provided at one end of the plug 110 connected to the housing 120. A plurality of grooves 122 are circumferentially provided inside the housing 120, and each boss 115 is engaged with a groove 122.

[0049] For example, the number of bosses 115 and grooves 122 can be two, three, four, five, or the like, depending on the size of the housing 120 and actual needs. The bosses 115 and grooves 122 cooperate with each other, allowing the bosses 115 of the plug 110 to engage with the corresponding grooves 122 during assembly of the plug 110 and the housing 120, positioning the plug 110 and facilitating installation. Furthermore, after assembly, the plug 110 is limited, preventing the front end of the connector from rotating relative to the housing 120. This effectively prevents the cable 200 from rotating during the locking and docking of the cable connector 100, thus preventing internal wire stranding and breakage.

[0050] It is understandable that in other embodiments, a groove 122 may be provided on the peripheral side of the plug 110 and a boss 115 may be provided inside the shell 120 , which can also satisfy the assembly positioning and matching of the plug 110 and the shell 120 .

[0051] Continue reading Figure 6 and Figure 7 As shown, in some embodiments, a first stopper 113 is provided on the circumference of the plug 110. The side of the first stopper 113 facing away from the plug end 111 abuts against the end surface of the housing 120. A first abutting portion 131 is provided inside the cap 130. After the cap 130 is locked with the housing 120, the first abutting portion 131 abuts against the side of the first stopper 113 facing away from the housing 120.

[0052] Specifically, the first limiting portion 113 is annularly fixed to the outer surface of the plug member 110 and protrudes relative to the surface of the plug member 110. The first abutting portion 131 is provided at the end where the cap body 130 is connected to the plug member 110 and extends inside the cap body 130. Therefore, after the cap body 130 is movably mounted on the plug member 110, the cap body 130 can rotate relative to the plug member 110, thereby tightening the cap body 130 to the housing 120. Furthermore, under the restriction of the first limiting portion 113, the cap body 130 cannot fall off the plug member 110 along the axial direction. When the cap body 130 and the housing 120 are locked, the first abutting portion 131 presses against the first limiting portion 113, and the cap body 130 pulls the first limiting portion 113 along the axial direction, further enhancing the assembly strength between the plug member 110 and the housing 120.

[0053] Continue reading Figure 8 and Figure 9As shown, in some embodiments, a clamping portion 123 is provided at one end of the housing 120 away from the plug 110. The cable connector 100 further includes a locking member 140, which is threadedly engaged with the end of the housing 120 away from the plug 110. The inner diameter of the inner wall of the locking member 140 away from the plug 110 decreases in a direction away from the housing 120 to form an inclined surface 141. The clamping portion 123 can be squeezed and contracted by the inclined surface 141 when the locking member 140 is rotated and locked relative to the housing 120.

[0054] Specifically, the clamping portion 123 has a certain elastic contraction property, so that it can shrink and gather under the action of external force. Through the integrated arrangement of the housing 120, the present application not only meets the requirements of cable 200 routing, but also locks and restricts the cable 200 through the clamping portion 123, reducing assembly time and production costs. The interior of the locking member 140 is provided with an internal thread, and the outer side of the end of the housing 120 away from the plug 110 is provided with an external thread, so that the locking member 140 can be locked or separated relative to the housing 120. During the assembly process of the cable connector 100, the end of the cable 200 away from the plug 110 is inserted into the clamping portion 123. When the locking member 140 is tightened, the inclined surface 141 abuts the clamping portion 123. As the inner diameter of the inclined surface 141 continuously decreases, the inclined surface 141 squeezes the clamping portion 123, causing the clamping portion 123 to shrink and gather, tightening and restraining the cable 200 passing through the housing 120, preventing the cable 200 from tangling, and improving the overall sealing performance.

[0055] Furthermore, the locking member 140 is further provided with a protrusion 142, which is located on the inclined surface 141. Due to the provision of the protrusion 142, during the rotation of the locking member 140, the protrusion 142 abuts against the locking portion of the housing 120, thereby increasing the friction between the locking member 140 and the housing 120 during the tightening process, making it difficult for the locking member 140 to fall off the housing 120 and cause problems such as thread slippage.

[0056] Continue reading Figure 10 As shown, in some embodiments, the clamping portion 123 is provided with a plurality of elastic blocks 1231 distributed circumferentially along the axis of the housing 120. A contraction gap is reserved between two adjacent elastic blocks 1231 so that when the locking member 140 is rotated and locked relative to the housing 120, each elastic block 1231 is squeezed and gathered by the inclined surface 141.

[0057] For example, the number of elastic blocks 1231 can be two, three, five, eight, ten, sixteen, etc., and can be selected based on actual needs. By providing a contraction gap between two adjacent elastic blocks 1231, when the elastic blocks 1231 are compressed by the inclined surface 141 of the locking member 140, the elastic blocks 1231 converge toward the axis, providing space for the elastic blocks 1231 to contract.

[0058] In some embodiments, the cable connector 100 further includes a sealing gasket 160, which is mounted on the inner side of the clamping portion 123. The sealing gasket 160 has a sleeve structure and simultaneously covers all cables 200. When the cables 200 are assembled in the housing 120, the sealing gasket 160 provides a waterproof seal at the contact points between the cables 200 and the housing 120, thereby reducing the risk of electrical leakage.

[0059] Continue reading Figure 11 As shown, in some embodiments, the cable connector 100 further includes a connecting member 150, which is rotatably mounted on the plug member 110 and has a second abutting portion 151 at one end thereof connected to the plug member 110. A second limiting portion 114 is provided on the outer side of the plug member 110. The second limiting portion 114 is disposed on a side of the first limiting portion 113 facing away from the housing 120, and the second abutting portion 151 is movably engaged with a side of the second limiting portion 114 that is closer to the first limiting portion 113.

[0060] Specifically, the second stopper 114 is positioned opposite the first stopper 113, forming a notch on the surface of the plug 110 between the second stopper 114 and the first stopper 113. The connector 150 is internally threaded, and one end of the connector, which includes the second abutment 151, is rotatably sleeved onto the second stopper 114, preventing the connector 150 from axially dislodging from the plug 110. During assembly with an external connector, after the plug 110 is plugged in, the connector 150 can be tightened to lock the plug 110 to the external connector, enhancing connection stability.

[0061] See again Figure 6 As shown, in some embodiments, the cable connector 100 further includes a first sealing ring 170 and a second sealing ring 180 . The first sealing ring 170 is disposed between the connector 150 and the plug 110 , and the second sealing ring 180 is disposed between the housing 120 and the plug 110 .

[0062] Specifically, the first sealing ring 170 is mounted on the side of the second abutting portion 151 facing away from the housing 120, and the second sealing ring 180 is mounted on the side of the first abutting portion 131 closer to the housing 120. The provision of the first sealing ring 170 and the second sealing ring 180 ensures that the cable connector 100 achieves waterproof sealing protection during both assembly and use, specifically achieving an IP (Ingress Protection Rating) of 67, thereby preventing the risk of electrical leakage in the cable connector 100.

[0063] In addition, in some embodiments, the surface of the cable connector 100 provided in the present application is further provided with a plurality of anti-slip grooves to facilitate the user's application of force during the locking and rotating process, thereby improving the performance of use.

[0064] An embodiment of the present application further provides an electrical device, comprising the cable connector 100 in any of the above embodiments.

[0065] This embodiment has the cable connector 100 in any of the above embodiments, and therefore has all the beneficial effects of the cable connector 100 in any of the above embodiments, which will not be described in detail here.

[0066] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
