Description

Technical Field

[0001] This utility model relates to the field of connector housing technology, specifically a quick-sealing connector housing with blind mating function. Background Technology

[0002] A connector is an electronic component used to connect two wires. With the increasing level of industrial automation, connectors are widely used in various applications. The connector housing is the outer shell of the connector, protecting the wires.

[0003] The prior art patent document CN219874224U provides a connector housing in which the force of the spring on the locking block causes the groove wall of the locking slot to abut against the outer surface of the wire, making it difficult for water on the wire to continue flowing into the through hole along the outer surface of the wire, thereby preventing water from damaging the wire.

[0004] The aforementioned existing technology protects the wires by providing a connector housing. However, existing connectors generally have a blind-mating function, that is, a protruding structure is provided at the front end of the plug housing, and a groove is provided inside the socket housing to cooperate with the protruding structure. In the case of limited space, blind mating can be achieved. However, this connection is not tight enough and the mechanical connection strength is insufficient. In practical applications, even a slight external force applied to the wire can cause the plug housing to detach from the socket housing, making it difficult to meet the requirements of a stable connection. Therefore, we need a quick-sealing connector housing with blind mating function. Utility Model Content

[0005] The purpose of this invention is to provide a quick-sealing connector housing with blind mating function to solve the problems mentioned in the background art.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a quick-sealing connector housing with blind-mating function, including a socket housing, a female connector fixedly connected to the inner wall of the socket housing, and a plug housing detachably connected to the inner wall of the socket housing, a male connector fixedly connected to the inner wall of the plug housing, a fixing component provided on the outer wall of the plug housing, an installation component provided on the inner wall of the plug housing, and a sealing groove provided on the inner wall of the plug housing, with a sealing ring provided on the inner wall of the sealing groove;

[0007] The fixing component includes a mounting groove, and a sliding rod is fixedly connected to the inner wall of the mounting groove. A first spring is fixedly connected to the inner wall of the mounting groove. A limit frame is slidably connected to the outer wall of the sliding rod, and a sliding groove is provided on the inner wall of the limit frame. A cover plate is detachably connected to the outer wall of the plug housing, and a fixing bolt is provided on the outer wall of the cover plate. A limit groove is provided on the inner wall of the socket housing.

[0008] The installation assembly includes a limiting rod, a second spring is fixedly connected to the inner wall of the plug housing, a sliding plate is slidably connected to the outer wall of the limiting rod, and a through groove is opened on the inner wall of the sliding plate. One end of the male connector is fixedly connected to a cable body, and a rubber plate is fixedly connected to the outer wall of the cable body.

[0009] Preferably, there are two mounting slots, and the two mounting slots are symmetrically arranged on the plug housing.

[0010] Preferably, one end of the slide rod extends into the slide groove, and the outer wall of the slide rod is in contact with the inner wall of the slide groove.

[0011] Preferably, the inner wall shape and size of the mounting groove match the outer wall shape and size of the limiting frame, and the inner wall of the mounting groove fits into the outer wall of the limiting frame.

[0012] Preferably, the plug housing is fixed to the cover plate by fixing bolts, and one end of the fixing bolt is threaded through the cover plate and extends into the plug housing for connection.

[0013] Preferably, the number of limiting rods is four, and two limiting rods form a group, with the two groups of limiting rods symmetrically arranged inside the plug housing.

[0014] Preferably, one end of the limiting rod passes through the through groove, and the outer wall of the limiting rod is in contact with the inner wall of the through groove.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] First, this utility model is equipped with an installation groove, a sliding rod, a first spring, a limiting bracket, a sliding groove, a cover plate, fixing bolts, and a limiting groove. When connecting the plug shell and the socket shell, the operator manually presses the limiting bracket, which retracts into the installation groove. The plug shell is then inserted into the socket shell. When the operator releases the hand, the first spring rebounds, pushing the limiting bracket to quickly engage in the limiting groove, thus achieving a blind insertion function. The connection is tight and will not separate from the socket shell due to slight pulling of the wire, meeting the requirements for a stable connection.

[0017] Secondly, this utility model is equipped with a limiting rod, a second spring, a sliding plate, a through groove, a cable body, and a rubber plate. When the cable body is subjected to external tension, the cable body will drive the rubber plate to move. The rubber plate pushes the sliding plate to slide along the limiting rod, causing the second spring to gradually contract. The elastic deformation of the second spring can effectively absorb and buffer the external force, preventing the tension from acting directly on the connection between the cable body and the male connector. In addition, the cable body has a certain amount of room for movement inside the plug shell, so that the cable body has a margin for movement under tension, which can effectively disperse the tension and prevent the cable from breaking or the connection from loosening due to excessive pulling. This significantly improves the reliability and service life of the connector under complex working conditions and ensures the stability and safety of the electrical connection.

[0023] 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.

[0024] like Figure 1-4As shown, a quick-sealing connector housing with blind-mating function includes a socket housing 1, a female connector 2 fixedly connected to the inner wall of the socket housing 1, and a plug housing 3 detachably connected to the inner wall of the socket housing 1. A male connector 4 is fixedly connected to the inner wall of the plug housing 3, a fixing component 5 is provided on the outer wall of the plug housing 3, an installation component 6 is provided on the inner wall of the plug housing 3, and a sealing groove 7 is formed on the inner wall of the plug housing 3, with a sealing ring 8 provided on the inner wall of the sealing groove 7. The fixing component 5 includes an installation groove 501, a slide rod 502 fixedly connected to the inner wall of the installation groove 501, and a first spring 503 fixedly connected to the inner wall of the installation groove 501. The outer wall of the rod 502 is slidably connected to the limiting frame 504, and the inner wall of the limiting frame 504 is provided with a sliding groove 505. The outer wall of the plug housing 3 is detachably connected to the cover plate 506, and the outer wall of the cover plate 506 is provided with fixing bolts 507. The inner wall of the socket housing 1 is provided with a limiting groove 508. The mounting assembly 6 includes a limiting rod 601. The inner wall of the plug housing 3 is fixedly connected to the second spring 602. The outer wall of the limiting rod 601 is slidably connected to the sliding plate 603, and the inner wall of the sliding plate 603 is provided with a through groove 604. One end of the connecting male end 4 is fixedly connected to the cable body 605, and the outer wall of the cable body 605 is fixedly connected to the rubber plate 606.

[0025] With the above technical solution, when connecting the plug housing 3 and the socket housing 1, the operator manually presses the limiting bracket 504, which retracts into the mounting groove 501. The plug housing 3 is then inserted into the socket housing 1. Upon releasing the hand, the first spring 503 rebounds, pushing the limiting bracket 504 to quickly engage in the limiting groove 508, achieving a blind insertion function. The connection is tight, and the plug housing 3 will not separate from the socket housing 1 due to slight pulling of the wire, meeting the requirements for a stable connection. When the cable body 605 is subjected to external tension, the cable body 605 will drive the rubber plate 606 to move, and the rubber plate 606 will push... The slide plate 603 slides along the limiting rod 601, causing the second spring 602 to gradually contract. The elastic deformation of the second spring 602 can effectively absorb and buffer external forces, preventing the tension from acting directly on the connection between the cable body 605 and the male terminal 4. In addition, the cable body 605 has a certain amount of room for movement inside the plug housing 3, so that the cable body 605 has a movable margin under the action of tension, which can effectively disperse the tension and prevent the cable from breaking or the connection from loosening due to excessive pulling. This significantly improves the reliability and service life of the connector under complex working conditions and ensures the stability and safety of the electrical connection.

[0026] Specifically, there are two mounting slots 501, and the two mounting slots 501 are symmetrically opened on the plug housing 3.

[0027] Through the above technical solution, the symmetrically distributed mounting grooves 501, together with the limiting bracket 504, can provide a stable limiting effect from both the top and bottom directions when the plug housing 3 is connected to the socket housing 1, making the connection force between the plug housing 3 and the socket housing 1 more uniform, further enhancing the stability of the connection structure, effectively resisting external force pulling in different directions, and preventing the connection from loosening; the socket housing 1 is provided with a stop block to facilitate the plug housing 3 to be inserted to the bottom, realizing the alignment of the limiting bracket 504 and the limiting groove 508.

[0028] Specifically, one end of the slide rod 502 extends into the slide groove 505, and the outer wall of the slide rod 502 is in contact with the inner wall of the slide groove 505.

[0029] Through the above technical solution, the cooperation between the slide bar 502 and the slide groove 505 provides guidance for the sliding of the limit frame 504, ensuring that the limit frame 504 can smoothly extend and retract along a fixed trajectory under the action of the first spring 503, and preventing the limit frame 504 from deviating or getting stuck during the sliding process.

[0030] Specifically, the inner wall shape and size of the mounting groove 501 match the outer wall shape and size of the limiting frame 504, and the inner wall of the mounting groove 501 fits against the outer wall of the limiting frame 504.

[0031] The above technical solution effectively reduces the swaying gap and improves the sliding stability when the limit frame 504 slides in the mounting groove 501.

[0032] Specifically, the plug housing 3 is fixed to the cover plate 506 by fixing bolt 507, and one end of the fixing bolt 507 is threaded through the cover plate 506 and extends into the plug housing 3 for connection.

[0033] With the above technical solution, there are multiple fixing bolts 507, which can effectively fix the cover plate 506 to the plug housing 3, making it easy to install and disassemble. When a part fails, the cover plate 506 can be disassembled to maintain and replace internal components such as the slide rod 502, the first spring 503, and the limit bracket 504.

[0034] Specifically, there are four limit rods 601, and two limit rods 601 form a group. The two groups of limit rods 601 are symmetrically arranged inside the plug housing 3.

[0035] With the above technical solution, when the slide plate 603 moves, the slide plate 603 slides more stably on the four limit rods 601, avoiding the slide plate 603 from tilting, and the movement of the slide plate 603 causes the four second springs 602 to be evenly stressed.

[0036] Specifically, one end of the limiting rod 601 passes through the through groove 604, and the outer wall of the limiting rod 601 is in contact with the inner wall of the through groove 604.

[0037] The above technical solution enhances the connection between the limiting rod 601 and the through groove 604. The limiting rod 601 acts as a guide, and when the slide plate 603 moves, the slide plate 603 moves more stably on the limiting rod 601 through the through groove 604.

[0038] In use, the operator first manually presses the limiting bracket 504. The limiting bracket 504 moves along the slide rod 502 via the slide groove 505. The movement of the limiting bracket 504 compresses the first spring 503, causing the limiting bracket 504 to retract into the mounting groove 501. The plug housing 3 is then aligned with the socket housing 1 and inserted until it is fully inserted. The operator releases the hand, and the first spring 503 rebounds, pushing the limiting bracket 504 to move and engage with the limiting groove 508 of the socket housing 1, completing the blind-plug connection between the plug housing 3 and the socket housing 1. At this time, the male connector 4 is inserted into the female connector 2, and the sealing ring 8 on the plug housing 3 is tightly fitted with the inner wall of the socket housing 1, forming a sealing structure. During subsequent use, if the cable body 605 is subjected to external tension, the cable body 605 will cause the rubber... When plate 606 moves, rubber plate 606 pushes slide plate 603 along limit rod 601, compressing second spring 602. The elastic deformation of second spring 602 can effectively absorb and buffer external force, preventing the pulling force from acting directly on the connection between cable body 605 and male terminal 4. In addition, cable body 605 has a certain amount of room for movement inside plug housing 3, so that cable body 605 has a movable margin under the action of pulling force, which can effectively disperse the pulling force and prevent cable breakage or loosening of connection due to excessive pulling. When disassembly is required, press limit bracket 504 again to retract it, and the plug housing 3 can be pulled out from socket housing 1. This completes all the work. The contents not described in detail in this specification are prior art known to those skilled in the art.

[0039] 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.
