Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a MINI waterproof cable connector. Background Technology

[0002] DIN connectors are a connector standard, and MINIDIN, as the name suggests, is smaller than a regular DIN connector. However, existing straight-insertion connectors have poor waterproof performance. A utility model application with application number CN202322790589.7 discloses a straight cable connector, including a socket, multi-layer insulators, and a shell. By optimizing the connector structure, it can meet the performance requirements of high power and high voltage resistance.

[0003] While the device possesses the aforementioned advantages, it still has certain shortcomings in practical use: Because the device provides waterproofing through two sets of sealing measures, one set of waterproofing measures is too close to the outer side of the connector. If the outer sealing measure is too tight, the connection between the connector and the connector head will have significant resistance, making the connection time-consuming and laborious. Conversely, insufficient tightness will easily lead to inadequate sealing. Therefore, it is necessary to address these remaining issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a MINI waterproof cable connector, which solves the problem that when using existing straight cable connectors, the sealing measures at the plug end are located close to the outside, which can easily lead to increased connection resistance with the connector head or insufficient connection tightness, resulting in a reduced connection sealing effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a MINI waterproof cable connector, comprising a housing, a sealing mechanism on the body of the housing, the sealing mechanism including an air passage, the air passage being opened on the body of the housing and having both sides of the interior being through, a rubber ring fixedly connected to one side of the air passage, a stop ring movably connected to the other side of the air passage, folded rings fixedly connected to both sides of the outer surface of the stop ring, a retaining ring fixedly connected to the outer surface of both folded rings, the outer surface of both retaining rings being fixedly connected to the interior of the air passage, a support ring fixedly connected to the interior of the air passage, a frustum fixedly connected through the body of the support ring, a groove being opened on one side of the outer surface of the frustum, a connecting hole being opened on the other side of the outer surface of the frustum, the interior of the connecting hole being connected to the interior of the air passage and the interior of the groove respectively.

[0006] Preferably, an insulator is fixedly connected inside the housing, and a pin is fixedly connected through the body of the insulator.

[0007] Preferably, one end of the pin is fixedly connected to a cable by soldering, and the shielding layer of the cable is fixedly connected to the outer surface of the housing by soldering.

[0008] Preferably, a threaded sleeve is rotatably connected to the outer surface of the housing, and a nut is fixedly connected to the outer surface of the threaded sleeve.

[0009] Preferably, a retaining ring is embedded in and rotatably connected to the outer surface of the housing, and the outer surface of the retaining ring is rotatably embedded in and connected to the inside of the threaded sleeve.

[0010] Preferably, a sealing ring is embedded at one end of the housing.

[0011] Beneficial effects

[0012] This invention provides a MINI waterproof cable connector. Compared with the prior art, it has the following advantages:

[0013] The connector abuts against the innermost abutment ring to achieve an internal seal. Simultaneously, the abutment ring moves into the air passage under force, compressing air from one side of the air passage to the other side. This causes the rubber ring to expand under force and fit tightly against the connector, thus achieving an external seal at the end of the connection. This double seal improves the sealing performance of the connection and reduces the damping effect in the early stages of the connection, thereby increasing the ease of connection.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a MINI waterproof cable connector.

[0020] The system includes a housing 3, on which a sealing mechanism 6 is provided. The sealing mechanism 6 includes an air passage 61, which is formed on the body of the housing 3 and has two through-holes inside. The two sides of the air passage 61 are perpendicular to the middle part. A rubber ring 62 is fixedly connected to one side inside the air passage 61. The rubber ring 62 is made of a material that is pressure-resistant, wear-resistant, easy to expand, and fatigue-resistant. A retaining ring 63 is movably connected to the other side inside the air passage 61. The retaining ring 63 is made of a material that is pressure-resistant, wear-resistant, and has high hardness, and has an arc-shaped cross-section to facilitate the contact of the connector. Folding rings 64 are fixedly connected to both sides of the outer surface of the retaining ring 63. The folding rings 64 are folded rings made of elastic material to facilitate the contact of the connector. The repositioning of the retaining ring 63 is achieved by fixing the outer surfaces of the two side folding rings 64 with a fixed ring 65. The fixed ring 65 is used to fix and support the folding ring 64, and its cross-section is triangular. Its hypotenuse facilitates airflow. The outer surfaces of the two side fixed rings 65 are fixedly connected to the interior of the air passage 61. The interior of the air passage 61 is fixedly connected with a support ring 66. The body of the support ring 66 is fixedly connected to a frustum 67. A groove 68 is provided on one side of the outer surface of the frustum 67, and a connecting hole 69 is provided on the other side of the outer surface of the frustum 67. The connecting hole 69 has a diameter difference from the groove 68, which facilitates air return and facilitates the disengagement of the rubber ring 62 from the connector. The interior of the connecting hole 69 is connected to the interior of the air passage 61 and the interior of the groove 68 respectively.

[0021] The connector abuts against the inner ring 63 to achieve an internal seal. At the same time, the ring 63 moves into the air passage 61 under force, compressing the air on one side of the air passage 61 to the other side. This causes the rubber ring 62 to expand under force and fit tightly against the connector, thus achieving an external seal at the end of the connection. This achieves a double seal to improve the sealing performance of the connection and reduces the damping effect in the early stage of the connection, thereby improving the ease of connection.

[0022] An insulator 2 is fixedly connected inside the housing 3. A pin 1 is fixedly connected through the body of the insulator 2. A cable 8 is fixedly connected to one end of the pin 1 by soldering. The shielding layer of the cable 8 is fixedly connected to the outer surface of the housing 3 by soldering. A threaded sleeve 5 is rotatably connected to the outer surface of the housing 3. A nut is fixedly connected to the outer surface of the threaded sleeve 5. The nut facilitates the rotation of the threaded sleeve 5. A retaining ring 4 is rotatably connected to the outer surface of the housing 3. The retaining ring 4 can limit the axis of the threaded sleeve 5. The outer surface of the retaining ring 4 is rotatably connected to the inside of the threaded sleeve 5. A sealing ring 7 is embedded at one end of the housing 3. The sealing ring 7 facilitates the installation of the housing 3 on the equipment and seals it tightly with the equipment.

[0023] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0024] During operation, firstly, the core wire of cable 8 is soldered to the pin 1. Then, the core wire and the shielding layer are soldered to one end of the housing 3 respectively. When in use, one end of the connector is aligned with the other end of the housing 3. Then, the nut is rotated to rotate the nut sleeve 5, and the nut sleeve 5 is connected to the thread of the connector, so that the connector slides axially into the inside of the nut sleeve 5, and the other end of the housing 3 is inserted into the connector, and the pin 1 is inserted into the connection hole of the connector.

[0025] During the sliding process of the connector, the connector first abuts against the innermost abutment ring 63. As it continues to slide, the abutment ring 63 is pressed into the air passage 61, thereby compressing the air inside the air passage 61 to the other side. This causes the rubber ring 62 to expand under force and fit tightly against the connector, thus achieving a double seal. When the connection is broken, the screw sleeve 5 is rotated in the opposite direction to allow the connector to slide out. After the abutment ring 63 disengages from the abutment, it is reset by the spring action of the folding ring 64. This reduces the air compression on the side corresponding to the abutment ring 63. Through the action of the groove 68 and the connecting hole 69, the air on the other side flows rapidly through the siphon effect, thus flowing back into the air passage 61 corresponding to the abutment ring 63. This reduces the air pressure inside the air passage 61 on the side of the rubber ring 62, causing the rubber ring 62 to be reduced in force and reshape itself, reducing the resistance to the reset of the connector.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
