Description

Technical Field

[0001] This utility model relates to the technical field of sheath sealing, and in particular to a skeleton sealing ring structure and sheath assembly. Background Technology

[0002] With the continuous advancement of new energy vehicle technology, the voltage platform has gradually upgraded from the traditional 100V fuel system to a 1000V high-voltage platform, with current requirements exceeding 600A. This shift places higher demands on the sealing structure of connectors.

[0003] Traditional sealing structures are prone to seal failure when faced with temperature rise, vibration and assembly pressure. The reasons for seal failure include a small temperature resistance range when faced with temperature rise, and inability to resist uneven thrust when faced with vibration and assembly pressure, making them easy to be squeezed out.

[0004] Therefore, there is an urgent need for a sealing structure that has a wide temperature range, can resist uneven thrust, and is not easily squeezed out. Utility Model Content

[0005] To address the shortcomings of the aforementioned background technology, this utility model proposes a skeleton sealing ring structure and a sheath assembly, which solves the technical problems of existing sealing structures having a small temperature resistance range when facing temperature rises, being unable to resist uneven thrust when facing vibration and assembly pressure, and being easily squeezed out.

[0006] The technical solution of this utility model is achieved as follows: a skeleton sealing ring structure includes a sealing ring, one side of which is provided with a plastic skeleton to prevent the sealing ring from being squeezed out under high pressure. The sealing ring is made of silicone rubber. The sealing ring of this application is made of silicone rubber, which can withstand a temperature range of -60℃ to 200℃ when exposed to temperature rise, thus having a wider temperature resistance range. The plastic skeleton on the side of the sealing ring can guide the sealing ring to compress evenly. At the same time, the plastic skeleton effectively resists the oblique insertion thrust of the plate end sleeve in the extreme installation space, ensuring that the sealing ring does not deform when subjected to uneven thrust. This allows the sealing ring to resist uneven thrust and prevent it from being squeezed out. Thus, the sealing ring achieves a wider temperature resistance range when exposed to temperature rise and can resist uneven thrust when exposed to vibration and assembly pressure. This solves the technical problems of existing sealing structures having a small temperature resistance range when exposed to temperature rise and being unable to resist uneven thrust when exposed to vibration and assembly pressure, making them prone to being squeezed out.

[0007] The plastic frame and sealing ring are both made of materials that ensure long-term sealing stability under high temperature, low temperature, vibration and salt spray environments.

[0008] Preferably, the plastic skeleton and the sealing ring are tightly connected through a vulcanization process. This tight connection between the plastic skeleton and the sealing ring improves the connection strength and reduces the risk of them separating.

[0009] Preferably, the plastic frame has a pre-reserved groove, the sealing ring has an installation groove, and the side wall of the pre-reserved protrusion has a pre-reserved protrusion. The plastic frame is inserted into the installation groove, and the pre-reserved groove and the pre-reserved protrusion are matched. When the plastic frame is inserted into the installation groove, the pre-reserved groove and the pre-reserved protrusion are matched, and the pre-reserved groove and the pre-reserved protrusion are tightly connected through a vulcanization process. The pre-reserved groove, installation groove, and pre-reserved protrusion are designed to ensure the sealing performance between the plastic frame and the sealing ring. The installation groove is designed for the insertion of the plastic frame. The pre-reserved groove and the pre-reserved protrusion are matched one-to-one.

[0010] Preferably, the plastic frame is provided with reinforcing ribs, which can make the plastic frame and the sealing ring fit more tightly.

[0011] Preferably, the sidewall of the sealing ring has a corrugated structure. The corrugated structure is designed to form a stable sealing interface after the sealing ring is compressed, ensuring that the dustproof and waterproof rating of the skeleton sealing ring structure of this application reaches IP6K9K / IP67.

[0012] Preferably, at least two wave crest structures are provided along the compression direction of the sealing ring. Providing at least two wave crest structures along the compression direction helps ensure a stable sealing interface after the sealing ring is compressed. Preferably, three wave crest structures are provided along the compression direction of the sealing ring.

[0013] Preferably, the mounting groove is disposed on the end face of the sealing ring. This application provides the mounting groove on the end face of the sealing ring to ensure that the plastic skeleton is connected to the end face of the sealing ring. This allows the extrusion force of the plate end sheath to be directly applied to the plastic skeleton on the end face of the sealing ring when the plate end sheath is inserted into the wire end sheath, effectively resisting the oblique insertion force of the plate end sheath in the limited installation space and ensuring that the sealing ring does not deform under uneven thrust.

[0014] A sheath assembly includes a plate-end sheath, a wire-end sheath, and the aforementioned skeleton sealing ring structure. The wire-end sheath has a pre-positioned location, and the skeleton sealing ring structure is fitted onto the pre-positioned location. When the plate-end sheath is inserted into the wire-end sheath, the plate-end sheath presses against the plastic skeleton on the skeleton sealing ring structure, assembling the skeleton sealing ring structure into its final position. The wire-end sheath serves to fix the skeleton sealing ring structure and provide a platform for mating with the plate-end sheath. The plate-end sheath is one end component of the connector, used for mating with another connecting component and inserted into the wire-end sheath. During assembly, the skeleton sealing ring structure is first fitted onto the pre-positioned location on the wire-end sheath, and then the plate-end sheath is inserted into the wire-end sheath. During insertion, the plate-end sheath pushes the skeleton sealing ring structure to its final position, at which point the plate-end sheath and the wire-end sheath are assembled.

[0015] Preferably, the plate end sheath is provided with a first positioning block and a second positioning block, and the wire end sheath is provided with a first positioning groove and a second positioning groove. When the plate end sheath is inserted into the wire end sheath, the first positioning block is inserted into the first positioning groove, and the second positioning block is inserted into the second positioning groove. The first positioning block, the second positioning block, the first positioning groove, and the second positioning groove are provided to ensure the positioning and insertion of the plate end sheath and the wire end sheath during the assembly process, and to ensure that the plate end sheath is accurately inserted into the wire end sheath.

[0016] Preferably, the first positioning block and the second positioning block are arranged perpendicularly. The perpendicular arrangement of the first positioning block and the second positioning block is to ensure positioning in two vertical directions, thereby improving the stability of the plate end sheath being accurately inserted into the line end sheath.

[0017] The beneficial effects of this utility model are:

[0018] The sealing ring of this application is made of silicone rubber. Silicone rubber sealing rings are suitable for a temperature range of -60℃ to 200℃ when exposed to temperature rise, thus having a wider temperature resistance range. A plastic skeleton is set on the side of the sealing ring. The plastic skeleton can guide the sealing ring to compress evenly. At the same time, the plastic skeleton can effectively resist the oblique insertion thrust of the plate end sleeve under extreme installation space, ensuring that the sealing ring does not deform when subjected to uneven thrust. This allows the sealing ring to resist uneven thrust and prevent the sealing ring from being squeezed out. Thus, the sealing ring achieves a wider temperature resistance range when exposed to temperature rise and can resist uneven thrust when exposed to vibration and assembly pressure.
