Description

Technical Field

[0001] The utility model relates to the technical field of electrical connectors, in particular to a connector and a connector plug thereof. Background Art

[0002] Connectors, including plugs and sockets, are widely used in various types of vehicles, communications, computers, consumer electronics, industry, transportation, and other fields. These vehicles include new energy vehicles, electric bicycles, electric motorcycles, and electric scooters. As key components, plugs and sockets bridge the gap between circuits, enabling current flow and enabling circuits to function as intended.

[0003] The sealing ring on existing connector plugs is inserted from the front end of the plug onto the outer diameter of the plug's rubber core. The sealing ring is a rubber elastic ring with an inner diameter smaller than the outer diameter of the plug's rubber core's head. During installation, the sealing ring is pre-stretched, causing it to plastically deform so that its inner diameter is larger than the outer diameter of the plug's rubber core's head. Once the sealing ring is in place, the pre-stretched ring recovers and becomes firmly fixed to the plug's rubber core's head. However, because the sealing ring is pre-stretched to secure it to the plug's rubber core's head, if the pre-stretching force is low or if the connector plug and receptacle mate and squeeze the sealing ring, it can become loose on the plug's rubber core, potentially causing it to fall off the plug's rubber core.

The two power lines are soldered to the two first conductive cylinders 4242 housed within the inner cavity of the second connecting portion 46, and the four electrical signal wires are soldered to the four second conductive cylinders 4262 housed within the inner cavity of the second connecting portion 46. In other embodiments, the fixing portion 44 may be, but is not limited to, a circular plate, a polygonal plate, an elliptical plate, or the like.

[0055] like Figure 1-Figure 3 and Figure 13-14As shown, when the connector plug 20 is plugged into the connector socket 40, the plug core 22 is inserted into the inner cavity of the socket core 42, the two power terminals 26 are respectively inserted into the first conductive cylinders 4242 of the two power plug cylinders 424, the four signal terminals 27 are respectively inserted into the four second conductive cylinders 4262 of the signal plug cylinder 426, and the locking sleeve 29 is sleeved on the socket core 42; the four positioning blocks 292 are respectively inserted into the four insertion sections 4221 of the socket core 42, and the second guide surfaces 2922 of the four positioning blocks 292 are respectively slidably pressed against the four first guide surfaces 4226 of the socket core 42, so as to drive the locking sleeve 29 to rotate relative to the plug core 22 along the first rotation direction, and the locking sleeve 29 squeezes The elastic return member 25 is elastically deformed; the connector plug 20 continues to be inserted into the connector socket 40, the second guide surface 2922 continues to slide relative to the first guide surface 4226, the locking sleeve 29 continues to rotate along the first rotation direction, and the elastic return member 25 is continued to be squeezed, so that the elastic return member 25 obtains a larger amount of compression, until the four positioning blocks 292 respectively pass over the four locking blocks 4224, the four positioning blocks 292 respectively face the four locking segments 4223, the elastic return member 25 elastically resets to drive the locking sleeve 29 to automatically rotate and reset along the second rotation direction, so that the four positioning blocks 292 are respectively locked in the four locking segments 4223, and the second rotation direction is opposite to the first rotation direction. At this time, the connector plug 20 is automatically locked to the connector socket 40 through the locking sleeve 29, the socket rubber core 42 contacts the rib 2212 of the plug rubber core 22, and the end surface of the socket rubber core 42 facing away from the second connecting portion 46 presses against the sealing ring 24, that is, the sealing ring 24 is sealed between the socket rubber core 42 and the plug rubber core 22, and the end of the socket rubber core 42 facing away from the second connecting portion 46 presses against the sealing ring 24 and covers the sealing ring 24 to enhance the sealing effect between the connector plug 20 and the connector socket 40; two power supplies The terminals 26 are electrically connected to the two first conductive tubes 4242, respectively, and the four signal terminals 27 are electrically connected to the four second conductive tubes 4262, respectively. The connector plug 20 and the connector socket 40 are automatically locked by the locking sleeve 29. The axial positioning of the connector plug 20 and the connector socket 40 ensures that the gap between the socket rubber core 42 and the plug rubber core 22 is not too small, thereby preventing the sealing ring 24 from being excessively compressed in the axial direction and causing the sealing ring 24 to collapse and fail, and also avoiding affecting the seal between the connector plug 20 and the connector socket 40.

[0056] When the connector plug 20 is unlocked from the connector socket 40, the operator holds the operating portion 294 of the locking sleeve 29 and applies a rotational force, causing the locking sleeve 29 to rotate in the first rotational direction. The positioning block 292 rotates in the corresponding locking section 4223 along the first rotational direction, and the elastic return member 25 is squeezed by the rotating block 291 and elastically deformed; when the four positioning blocks 292 are respectively facing the four insertion sections 4221, the connector plug 20 is pulled out in the direction away from the connector socket 40 until the four positioning blocks 292 are respectively disengaged from the four insertion sections 4221, and the connector plug 20 is disengaged from the connector socket 40; the rotational force on the locking sleeve 29 is released, and the elastic return member 25 elastically returns to drive the locking sleeve 29 to rotate and return to its original position, so as to facilitate the next connection between the connector plug 20 and the connector socket 40.

[0057] The connector plug 20 and the connector socket 40 of the connector 100 of the present application are automatically locked by the locking sleeve 29, which not only facilitates the plug-in locking of the connector plug 20 and the connector socket 40, but also the positioning block 292 is positioned in the locking groove 422, so that the locking of the connector plug 20 and the connector socket 40 is stable and firm; in addition, the sealing ring 24 is sealed and clamped between the socket rubber core 42 and the plug rubber core 22, thereby improving the waterproof function of the connector 100; the sealing ring 24 is positioned in the positioning groove 2215 by multiple positioning protrusions 2214, thereby preventing the sealing ring 24 from falling off the plug rubber core 22.

[0058] like Figures 15-19 As shown, the structure of the connector plug 20a in the second embodiment of the present application is similar to that of the connector plug 20 in the first embodiment, except that the structure of the sealing ring 24a and the positioning structure between the sealing ring 24a and the positioning portion 220a in the second embodiment are different from the structure of the sealing ring 24 and the positioning structure between the sealing ring 24 and the positioning portion 220 in the first embodiment. Specifically, the positioning portion 220a in the second embodiment is based on the positioning portion 220 in the first embodiment, but omits the rib 2212 and the positioning bump 2214. The sealing ring 24a is bonded to the positioning step surface 2202 via a positioning structure. Specifically, the positioning structure can be, but is not limited to, self-adhesive stickers, glue, connecting adhesive, double-sided tape, etc. The sealing ring 24a has a contact surface 241, which is positioned on the positioning step surface 2202 by connecting glue; the inner circumferential surface of the sealing ring 24a is provided with a plurality of protrusions 242, and the plurality of protrusions 242 are arranged at intervals around the circumference of the sealing ring 24a. When the sealing ring 24a is sleeved on the plug-in portion 225, the plurality of protrusions 242 press against the outer circumferential surface of the plug-in portion 225.

[0059] In this embodiment, multiple protrusions 242 are evenly spaced around the circumference of the sealing ring 24a. Specifically, eight protrusions 242 are evenly spaced around the inner circumference of the sealing ring 24a. A raised ring 243 is provided on the surface of the sealing ring 24a facing away from the positioning step surface 2202. The raised ring 243 is located near the inner circumference of the sealing ring 24a. When the connector plug 20a is inserted into the connector receptacle, the end face of the receptacle rubber core of the connector receptacle abuts against the raised ring 243 of the sealing ring 24a, effectively clamping the sealing ring 24a between the positioning portion 220 and the receptacle rubber core.

[0060] The sealing ring 24a of the connector plug 20a in this embodiment is directly sleeved on the plug-in portion 225. Under the action of pre-stretching, the inner radial direction of the sealing ring 24a and the outer diameter of the plug-in portion 225 will produce a radial tightening effect, and the sealing ring 24a is bonded to the positioning step surface 2202 of the positioning portion 220 by connecting glue, which can make the sealing ring 24a stably positioned on the connector plug 20a in the radial and axial directions, thereby increasing the axial fixing force of the sealing ring 24a, preventing loosening, and reducing the possibility of the sealing ring 24a falling off the plug-in portion 225.

[0061] Optionally, the outer peripheral surface of the locking sleeve 29 a in the second embodiment adopts an anti-slip groove 296 to replace the operating portion 294 of the locking sleeve 29 in the first embodiment.

[0062] The connector plug and connector of the present invention can be widely used in various fields such as automobiles, communications, computers, consumer electronics, industry, and transportation. For example, they can be used as key components in new energy vehicles, electric bicycles, electric motorcycles, electric scooters, and more specifically in motors of various types of vehicles. Their applications are very broad and not limited to these examples.
