Description

Technical Field

[0001] The present invention relates to a male connector with a cut-off function, belonging to the technical field of automotive parts. Background Art

[0002] In recent years, with the increasingly deteriorating environment and the increasing pressure on the overall vehicle cost, in the automotive pipeline system, a more environmentally friendly, low-cost and safe automotive pipeline system has become the future development trend.

[0003] The automotive pipeline system includes oil pipes (such as fuel inlet pipes, fuel return pipes, etc.), water pipes (such as cooling water circulation pipes, antifreeze pipes, etc.) and air pipes (such as crankcase ventilation pipes). These pipelines need to be split according to various requirements such as installation, maintenance, modular layout, space, etc. in the overall vehicle layout, and quick connection is required during assembly of the assembly or the whole vehicle. Due to the characteristics of convenient connection and simple operation, quick connectors are the most common connection method.

[0004] In some application scenarios, it is required that the quick connector has a cut-off function. At present, the cut-off function is set inside the standard connector, but the flow is blocked very seriously. Generally, connectors of 1-2 larger standard models are used to replace it, and both the female connector and the male connector need to be enlarged simultaneously, and the appearance will also increase synchronously, increasing the cost. Moreover, the male connector with a cut-off function is always used in combination with the female connector. If the form of the female connector is changed, the cut-off function will fail, and the applicability is poor. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a male connector with a cut-off function for the above-mentioned existing technology, which can realize the cut-off function without being used in combination with a special female connector. The requirement for the female connector is only to match in specifications, and the conduction function can be realized by connecting the two, improving the applicability and ensuring that the flow in the flow channel is not damaged.

[0006] The technical solution adopted by the present invention to solve the above problems is: a male connector with a cut-off function, including a male connector body and a connecting head.

[0007] A stepped flow channel is arranged at the center of the male connector body, and a plurality of vertically penetrating pin ports are opened on the male connector body. The plurality of pin ports are circumferentially and uniformly distributed outside the stepped flow channel.

[0008] The connecting head includes a connecting head body. A shoulder is arranged on the bottom surface of the connecting head body. The bottom of the shoulder is provided with circumferentially and uniformly distributed pins, and the pins are matched with the pin ports. A connecting head flow channel is provided at the center of the connecting head body. A partition is arranged in the connecting head flow channel. The partition is connected to the connecting head body through a plurality of vertically arranged connecting pieces. Channel openings are respectively formed between adjacent connecting pieces, and the channel openings are respectively communicated with the connecting head flow channel.

[0009] The pins are inserted into the corresponding pin openings, so that the partition is arranged in the variable diameter flow channel; an inner sealing ring is provided in the variable diameter flow channel, and the bottom of the partition is against the inner sealing ring;

[0010] A compression spring is sleeved on the outer periphery of the connector body, and an end cover is provided on the top of the male connector body. The compression spring is arranged between the boss and the end cover. The elastic force of the compression spring pushes the boss to move, driving the connector body to be close to the male connector body, so that the bottom of the partition piece is close to the inner sealing ring, thereby realizing that the variable diameter flow channel is in a partition state.

[0011] The variable-diameter flow channel includes a first flow channel and a second flow channel, the first flow channel is arranged above the second flow channel, the diameter of the first flow channel is larger than the diameter of the second flow channel, the first flow channel and the second flow channel are connected by a connecting flow channel, and the inner sealing ring is arranged in the connecting flow channel.

[0012] A limiting ring is provided on the inner wall of the male connector body. The limiting ring is provided at the outlet end of the first flow channel. A retaining ring is provided between the limiting ring and the inner sealing ring.

[0013] A guide groove is provided on the top of the pin opening so that a limiting step is formed at the connection between the pin opening and the guide groove. The pin is inserted into the pin opening through the guide groove so that the boss is supported on the limiting step and the bottom of the pin is exposed from the lower end surface of the male connector body.

[0014] A connecting boss is provided at the bottom of the male connector body, and the bottom of the pin is provided above the connecting boss; when the male connector body and the female connector are assembled, the upper end surface of the female connector pushes the bottom of the pin to move upward, driving the partition piece to move upward synchronously so that the bottom of the partition piece is away from the inner sealing ring and the retaining ring, and the boss compresses the compression spring to achieve conduction between the first flow channel, the connecting flow channel and the second flow channel; when the upper end surface of the female connector is pressed against the lower end surface of the male connector body, the connecting boss of the male connector body and the elastic undercut of the female connector are fastened.

[0015] The lower end surface of the male connector body is provided with a clearance groove

[0016] An outer sealing ring is provided between the outer wall of the male connector body and the inner wall of the connector body.

[0017] The retaining ring is provided with a funnel-shaped central hole, which has a guiding effect on the medium when the first flow channel and the second flow channel are connected.

[0018] Compared with the prior art, the advantages of the present invention are as follows: For a male connector with a cut-off function, when used alone, the elastic force of the compression spring generates a reverse acting force on the connector and the male connector body, causing the bottom of the partition member to abut against the inner sealing ring, realizing that the variable-diameter flow channel is in a cut-off state, that is, the medium in the variable-diameter flow channel cannot flow out; when the present application is assembled with the female connector, the upper end surface of the female connector pushes the pin upward, driving the partition member to move upward synchronously, and causing the bottom end of the partition member to move away from the inner sealing ring and the retaining ring, and the shoulder compresses the compression spring, realizing that the variable-diameter flow channel is in a conducting state. When the female connector is pulled out, the variable-diameter flow channel is automatically cut off. The present application can achieve the cut-off function without docking with a special female connector; the requirement for the female connector is only to match in specifications, and the two can be connected to achieve the conducting function, without additional requirements for the structure of the female connector, and it has wide applicability.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The present invention will be further described in detail below with reference to the embodiments of the drawings.

[0028] AsFigure 1 , 2 As shown in Figures 3, 4, 5, and 6, a male connector with a cut-off function in this embodiment includes a male connector body 7 and a connector 3. The male connector body 7 has a stepped flow channel in the center. The stepped flow channel includes a first flow channel 7.1 and a second flow channel 7.8. The first flow channel 7.1 is located above the second flow channel 7.8. The diameter of the first flow channel 7.1 is larger than that of the second flow channel 7.8. The first flow channel 7.1 and the second flow channel 7.8 are transitionally connected through a connecting flow channel 7.3. Three vertically penetrating pin openings 7.6 are formed on the male connector body 7. The pin openings 7.6 are arc-shaped structures protruding both inside and outside, and the three pin openings 7.6 are circumferentially and evenly arranged outside the stepped flow channel. A guiding groove 7.5 is formed at the top of the pin opening 7.6, so that a limiting step is formed at the connection between the pin opening 7.6 and the guiding groove 7.5. The connector 3 includes a connector body 3.1. A ring-shaped shoulder 3.2 is provided on the bottom surface of the connector body 3.1. The bottom of the shoulder 3.2 is provided with circumferentially distributed pins 3.5. The pins 3.5 are matched with the pin openings 7.6, and the inner wall of the pins 3.5 is flush with the inner wall of the connector body 3.1. The connector body 3.1 has a connector flow channel in the center, and a partition 3.4 is provided in the connector flow channel. A groove is formed on the top surface of the partition 3.4. Four vertically arranged connecting members 3.3 are provided above the partition 3.4. The four connecting members 3.4 are circumferentially and evenly distributed along the groove. The top end of the connecting member 3.3 is connected to the inner wall of the connector body 3.1, and the bottom end of the connecting member 3.3 is connected to the top end of the partition 3.4. Rectangular channel openings are respectively formed between adjacent connecting members 3.3. The channel openings are communicated with the connector flow channel, ensuring that the flow rate in the connector flow channel is not damaged. The pins 3.5 are inserted into the pin openings 7.6 through the guiding grooves 7.5, and the shoulder 3.2 is supported on the limiting step. The limiting step limits the insertion depth of the pins 3.5. At this time, the partition 3.4 and the connecting members 3.3 are arranged in the first flow channel 7.1, and the bottom of the partition 3.4 is located at the connecting flow channel 7.3. A retaining ring 5 is provided at the outlet end of the first flow channel 7.1, and an inner sealing ring 6 is provided in the connecting flow channel 7.3, so that the bottom of the partition 3.4 sequentially penetrates through the retaining ring 5 and the inner sealing ring 6. A compression spring 2 is sleeved outside the connector body 3.1, and an end cover 1 is provided at the top of the male connector body 7. The compression spring 7 is arranged between the shoulder 3.2 and the end cover 1. The elastic force of the compression spring 7 pushes the shoulder 3.2 to closely adhere to the limiting step, thereby driving the connector body 3.1 to closely adhere to the male connector body 7, so that the bottom of the partition 3.4 closely adheres to the inner sealing ring 6. The partition 3.4 and the inner sealing ring 6 cooperate with each other, so that the first flow channel 7.1 and the second flow channel 7.8 are in a cut-off state, that is, the stepped flow channel is in a cut-off state. The medium in the connector flow channel flows into the first flow channel 7.1 through the four channel openings and is sealed in the first flow channel, having the function of cutting off the medium.

[0029] A limiting ring 7.2 is provided on the inner wall of the male connector body 7. The limiting ring 7.2 is provided at the outlet end of the first flow channel 7.1 to limit the retaining ring 5 and the inner sealing ring 6 to ensure that the retaining ring and the inner sealing ring do not move.

[0030] After the pin is inserted into the pin opening, the bottom of the pin is exposed from the lower end surface of the male connector body.

[0031] like Figure 7 As shown, a connecting boss 7.9 is provided at the bottom of the male connector body 7. When the male connector body and the female connector 8 are assembled, the upper end face of the female connector pushes the bottom of the pin upward, driving the partition piece to move upward synchronously, causing the bottom end of the partition piece to move away from the inner sealing ring and the retaining ring. The boss compresses the compression spring, achieving communication between the first flow channel, the connecting flow channel, and the second flow channel. That is, the medium in the connector channel flows into the first flow channel through the flow port, and then the medium in the first flow channel flows into the second flow channel through the center hole of the retaining ring and the center hole of the inner sealing ring. When the upper end face of the female connector is pressed against the lower end face of the male connector body, the connecting boss of the male connector body and the elastic undercut of the female connector are fastened, completing the assembly between the male connector body and the female connector. At the same time, communication is achieved between the connector channel, the first flow channel, the second flow channel, and the inner cavity of the female connector, ensuring normal flow of the medium.

[0032] A clearance groove is provided on the bottom surface of the male connector body to ensure that the male connector body and the female connector are assembled in place.

[0033] An outer sealing ring is provided between the outer wall of the joint body and the inner wall of the connector body to prevent leakage of the medium.

[0034] The retaining ring is provided with a funnel-shaped central hole, which has a guiding effect on the medium when the first flow channel and the second flow channel are connected.

[0035] The end cover and the male connector body are split structures, which is convenient for installing the inner sealing ring, retaining ring, outer sealing ring and compression spring.

[0036] When the upper end surface of the female connector is pressed against the lower end surface of the male connector body, the movement of the connector is restricted.

[0037] When this application is used alone, the elastic force of the compression spring exerts an opposite force on the connector and the male connector body, causing the bottom of the partition piece and the inner sealing ring to press against each other, realizing that the variable diameter flow channel is in a cut-off state, that is, the medium in the variable diameter flow channel cannot flow out; when this application is assembled with the female connector, the upper end face of the female connector pushes the pin to move upward, driving the partition piece to move upward synchronously, so that the bottom end of the partition piece is away from the inner sealing ring and the retaining ring, and the boss compresses the compression spring, realizing that the variable diameter flow channel is in a conductive state. When the female connector is pulled out, the variable diameter flow channel is automatically cut off. This application can realize the cut-off function without docking with a dedicated female connector; the requirement for the female connector is only to match the specifications, and the conductive function can be realized by connecting the two. There are no additional requirements for the structure of the female connector, and it has a wide range of applicability.

[0038] In addition to the above embodiments, the present invention also includes other implementation manners. Any technical solutions formed by equivalent transformation or equivalent substitution shall fall within the protection scope of the claims of the present invention.
