Description

Technical Field

[0001] This invention relates to the field of automotive electrical devices, and more specifically to a female end structure of a lever-assisted connector. Background Technology

[0002] Connectors are used to achieve electrical connections and signal transmission between electronic devices, establishing circuit connectivity through the crimping of male and female terminals. In recent years, with the rapid development of the automotive industry, vehicles have increasingly higher requirements for space allocation, demanding more space for passenger and driver comfort. This places higher demands on connectors, requiring them to be smaller and more precise.

[0003] This means that there need to be more signal pairs in the same space. Due to the lack of assist mechanism on the connector, insertion and removal become extremely difficult, and this defect becomes more and more significant as the density of connectors increases. Some connectors require a force of more than ten kilograms to insert or remove, which is not in line with ergonomic design. In addition, as automotive connectors, they will inevitably experience continuous or even large-amplitude vibrations during normal operation. Existing connectors lack a locking device for mating, resulting in low mating reliability and safety hazards. Summary of the Invention

[0004] In view of the aforementioned problems, this application is proposed to provide a female end structure for a lever-assisted connector that overcomes or at least partially solves the aforementioned problems, comprising: The system comprises a female end housing, an inner rubber housing, and an auxiliary rocker arm; the auxiliary rocker arm is rotatably connected to the female end housing. The inner rubber shell is provided with a limiting boss, and the female end shell is provided with a limiting groove that cooperates with the limiting boss. Near the limiting groove is a lever arm groove for providing elastic fit. The female end shell and the inner rubber shell are fixedly connected by the limiting boss and the limiting groove. When the inner shell is installed into the female end shell, the female end shell causes the shell structure near the limiting groove to elastically deform through the lever groove, forming a displacement space for the limiting boss to move to the limiting groove.

[0005] Specifically, the female end housing is provided with rotating shafts on both sides, and the assist rocker arm is provided with a rotating shaft hole for passing through the rotating shaft. The assist rocker arm and the female end housing are hinged through the rotating shaft and the rotating shaft hole that cooperate with each other, and the assist rocker arm can rotate around the rotating shaft.

[0006] Specifically, one side of the female end housing is provided with an opening for inserting the inner rubber shell.

[0007] Specifically, the end of the lever arm groove facing the opening direction is set as an opening, the length of the lever arm groove is greater than that of the limiting groove, and the lever arm groove is parallel to the insertion direction of the inner rubber shell.

[0008] Specifically, the inner rubber shell includes a first inner rubber shell and a second inner rubber shell. The first inner rubber shell is provided with a guide rail, and the second inner rubber shell is provided with a groove that cooperates with the guide rail. The first inner rubber shell and the second inner rubber shell are slidably connected through the guide rail and the groove.

[0009] Specifically, the non-adhesive surfaces of the first inner shell and the second inner shell are respectively provided with grooves, and the inner sides of the female end shell are respectively provided with guide rails that cooperate with the grooves. The first inner shell and the second inner shell are slidably connected to the female end shell.

[0010] Specifically, the female end housing is provided with a main lock structure that cooperates with the rocker arm; When the assist rocker arm is rotated to the pressing position, the main locking structure abuts against the assist rocker arm to fix it in place.

[0011] Specifically, the female end housing is provided with a protrusion, and the assist rocker arm is provided with a limiting hole that cooperates with the protrusion; When the power-assisted rocker arm is rotated to the disengaged position, the convex bulge engages with the limiting hole to lock the power-assisted rocker arm.

[0012] Specifically, the female end housing is provided with a rocker arm limiting post, which abuts against the assist rocker arm to limit the assist rocker arm.

[0013] A lever-assisted connector includes a male end and a female end structure of a lever-assisted connector as described in any embodiment of this application; The female end housing is adapted to be inserted into the male end, the male end is provided with a male end gear, and the assist rocker arm is provided with a rocker arm gear that meshes with the male end gear.

[0014] This application has the following advantages: In the embodiments of this application, addressing the problems of difficult connector insertion and removal and low mating reliability in the prior art, this application provides a solution for realizing the male and female end housings through an assisting rocker and a mating locking structure, specifically: "Including a female end housing, an inner rubber housing, and an assisting rocker; the assisting rocker is rotatably connected to the female end housing; the inner rubber housing is provided with a limiting boss, the female end housing is provided with a limiting groove that cooperates with the limiting boss, and a lever arm groove is provided near the limiting groove for providing elastic fit; the female end housing and the inner rubber housing are fixedly connected through the limiting boss and the limiting groove; when the inner rubber housing is installed into the female end housing, the female end housing elastically deforms the housing structure near the limiting groove through the lever arm groove, forming a displacement space for the limiting boss to move to the limiting groove." The female end housing and the inner rubber housing are connected and fixed by a sliding connection structure and a locking structure that cooperate with each other. When the male end and the female end housing are mated to the pre-insertion position, the assist rocker arm drives the female end housing downward to press against the male end. This solves the problems of difficult insertion and removal and low mating reliability of existing connector devices, and achieves the technical effect of allowing the male and female end housings of the connector to be inserted and removed with less effort. The operation of the assist rocker arm to realize the insertion and removal action is more in line with the ergonomic design. After the inner rubber housing is inserted into the female end housing, it is limited and fixed by the locking structure that cooperates with each other, ensuring the stable pressing of the male and female end housings of the connector and improving the mating reliability.

[0017] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0018] The inventors discovered through analysis of existing technologies that: a higher density of connectors makes it very difficult to insert and remove the male and female shells of the connector. The lack of auxiliary structures on the connectors for insertion and removal, and the direct application of force to the male and female shells, is not in line with ergonomic design, making it difficult to apply force during insertion and removal. Furthermore, due to the characteristics of their working conditions, they need to withstand continuous and even large-amplitude vibrations. Existing connectors lack a locking structure to limit and fix the male and female shells after they are pressed together, which can cause the connectors to loosen or even separate, resulting in low mating reliability and safety hazards.

[0019] Reference Figure 1 The diagram shows an exploded view of the female end structure of a lever-assisted connector according to an embodiment of this application: it includes a female end housing 100, an inner rubber housing 200, and an assist rocker arm 400; the assist rocker arm 400 is rotatably connected to the female end housing 100. The inner rubber shell 200 is provided with a limiting boss 230, and the female end shell 100 is provided with a limiting groove 110 that cooperates with the limiting boss 230. A lever arm groove 120 for providing elastic fit is provided near the limiting groove 110. The female end shell 100 and the inner rubber shell 200 are fixedly connected by the limiting boss 230 and the limiting groove 110. When the inner shell 200 is installed into the female end shell 100, the female end shell 100 causes the shell structure near the limiting groove 110 to elastically deform through the lever groove 120, forming a displacement space for the limiting boss 230 to move into the limiting groove.

[0020] In the embodiments of this application, addressing the problems of difficult insertion and removal and low mating reliability of connectors in the prior art, this application connects and fixes the female end housing 100 and the inner rubber housing 200 through the mutually cooperating sliding connection structure and the locking structure. When the male end 300 and the female end housing 100 are mated to the pre-insertion position, the assist rocker 400 drives the female end housing 100 downward to press against the male end 300, solving the problems of difficult insertion and removal and low mating reliability of existing connector devices. This achieves the technical effect of allowing the male and female end housings of the connector to be inserted and removed with less effort. The operation of the assist rocker to realize the insertion and removal action is more in line with ergonomic design. After the inner rubber housing is inserted into the female end housing, it is limited and fixed by the mutually cooperating locking structure, ensuring stable pressing of the male and female end housings of the connector and improving mating reliability.

[0021] The following will further describe a lever-assisted connector in this exemplary embodiment.

[0022] In one embodiment of this application, the specific features of the female end structure of the pull rod assist connector can be further described in conjunction with the following description.

[0023] like Figure 1 As shown, in one embodiment of this application, it includes a female end housing 100, an inner rubber housing 200, and an auxiliary rocker arm 400; the auxiliary rocker arm 400 is rotatably connected to the female end housing 100. The inner rubber shell 200 is provided with a limiting boss 230, and the female end shell 100 is provided with a limiting groove 110 that cooperates with the limiting boss 230. Near the limiting groove, there is a lever arm groove 120 for providing elastic fit. The female end shell 100 and the inner rubber shell 200 are fixedly connected by the limiting boss 230 and the limiting groove 110. When the inner shell 200 is installed into the female end shell 100, the female end shell 100 causes the shell structure near the limiting groove 110 to elastically deform through the lever groove 120, forming a displacement space for the limiting boss 230 to move to the limiting groove 110.

[0024] It should be noted that the limiting boss 230 and the limiting groove 110 cooperate with each other to fasten and connect the inner rubber shell 200 and the female end shell 100 to achieve initial fixation. The inner rubber shell 200 is inserted into the female end shell 100 to form a complete female end. The stability of the inner rubber shell 200 is ensured during the insertion and removal operations of the female end shell 100 and the male end 300.

[0025] In one specific implementation, the inner shell 200 is inserted into the female end shell 100 and fixed by the mutually cooperating limiting boss 230 and limiting groove 110, thereby aligning the female end shell 100 and the male end 300 to the pre-insertion position. The pressing of the female end shell 100 and the male end 300 is achieved by operating the assist rocker arm 400.

[0026] like Figure 1-4 As shown in one embodiment of this application, the female end housing 100 is provided with rotating shafts 130 on both sides, and the assist rocker 400 is provided with a rotating shaft hole 430 for passing through the rotating shaft 130. The assist rocker 400 and the female end housing 100 are hinged to each other through the rotating shaft 130 and the rotating shaft hole 430, and the assist rocker 400 can rotate around the rotating shaft 130.

[0027] It should be noted that the rotating shaft 130, the rotating shaft hole 430, the rocker gear 410, and the male end gear 310 form a force transmission structure for insertion and extraction. The force of turning the power rocker 400 is transmitted through the meshing force of the rocker gear 410 and the male end gear 310, as well as the force transmission through the hinged rotating shaft 130 and the rotating shaft hole 430, and is converted into a force that drives the female end housing 100 to insert and extract, pressing or separating the female end housing 100 and the male end 300.

[0028] like Figure 1 and Figure 3 As shown, in one embodiment of this application, the female end housing 100 has an opening on one side for inserting the inner rubber housing 200; The lever arm groove 120 is configured to open at one end facing the opening direction, the length of the lever arm groove 120 is greater than that of the limiting groove 110, and the lever arm groove 120 is parallel to the insertion direction of the inner rubber shell 200.

[0029] It should be noted that the lever arm groove 120 is the core inventive point of this application. The elastic fit provided by the lever arm groove 120 is the key to realizing the fastening connection between the limiting boss 230 and the limiting groove 110.

[0030] In one specific implementation, when the inner rubber shell 200 is inserted into the female end shell 100 through the opening, due to the elastic effect provided by the lever groove 120, the limiting boss 230 can push up the shell near the limiting groove 110 and smoothly slide into the limiting groove 110. When the limiting boss 230 falls into the limiting groove 110, the shell will immediately return to its original position, and the limiting boss 230 and the limiting groove 110 will be engaged and connected, thereby achieving the effect of limiting and locking the inner rubber shell 200 and the female end shell 100.

[0031] like Figure 5 As shown, in one embodiment of this application, the inner rubber shell 200 includes a first inner rubber shell 210 and a second inner rubber shell 220. The first inner rubber shell 210 is provided with a guide rail 240, and the second inner rubber shell 220 is provided with a groove 250 that cooperates with the guide rail 240. The first inner rubber shell 210 and the second inner rubber shell 220 are slidably connected through the guide rail 240 and the groove 250.

[0032] As an example, the number of the first inner shell 210 and the second inner shell 220 can be increased according to actual usage requirements. For example, when the number of signal pairs in the circuit device increases, one more first inner shell 210 can be added to form a multi-layer inner shell structure of "first inner shell 210-second inner shell 220-first inner shell 210".

[0033] like Figure 1 and Figure 5 As shown, in one embodiment of this application, the non-adhesive surfaces of the first inner shell 210 and the second inner shell 220 are respectively provided with grooves 250, and the inner sides of the female end shell 100 are respectively provided with guide rails 240 that cooperate with the grooves 250. The first inner shell 210 and the second inner shell 220 are slidably connected to the female end shell 100.

[0034] In one specific implementation, the first inner shell 210 and the second inner shell 220 are installed into the female end housing 100 through the opening via the mutually cooperating guide rail 240 and the groove 250. The first inner shell 210, the second inner shell 220 and the female end housing 100 are assembled as the female end of the connector.

[0035] It should be noted that, in addition to serving as a sliding guide, the guide rail 240 and the groove 250, after assembly, also serve to fasten and connect the inner rubber shell 200 to the female end shell 100.

[0036] like Figure 3 As shown, in one embodiment of this application, the female end housing 100 is provided with a main lock structure 140 that cooperates with the assist rocker arm 400; When the assist rocker arm 400 is rotated to the pressing position, the main locking structure 140 abuts against the assist rocker arm 400 to fix it in place.

[0037] In one specific implementation, when the assist rocker arm 400 is rotated to the pressing position, the main locking structure 100 abuts against the assist rocker arm 400. Through the meshing of the rocker gear and the male end gear, and the hinge of the rotating shaft and the rotating shaft hole, the pressing and locking of the female end housing 100 and the male end 300 is achieved.

[0038] like Figure 3-4 As shown, in one embodiment of this application, the female end housing 100 is provided with a protrusion 150, and the assist rocker arm 400 is provided with a limiting hole 420 that cooperates with the protrusion 150. When the assist rocker arm 400 is rotated to the disengaged position, the protrusion 150 engages with the limiting hole 420 to lock the assist rocker arm 400.

[0039] It should be noted that the limiting holes 420 are respectively provided on the two end plates of the power rocker arm 400. The elastic fit between the end plates and the protrusion 150 is the key to realizing the fastening connection between the protrusion 150 and the limiting holes 420.

[0040] In one specific implementation, the assist rocker arm 400 rotates from the pressing position to the separating position, the protrusion 150 lifts the end plate, and the end plate undergoes elastic deformation to form a displacement space for the protrusion 150 to move to the limiting hole. When the protrusion 150 falls into the limiting hole 420, the end plate will immediately return to its original position, and the protrusion 150 and the limiting hole 420 will be engaged, locking the assist rocker arm 400 in the separating position.

[0041] like Figure 3-4 As shown, in one embodiment of this application, the female end housing 100 is provided with a rocker arm limiting post 160, which abuts against the assist rocker arm 400 to limit the assist rocker arm 400.

[0042] It should be noted that when the convex 150 engages with the limiting hole 420, the rocker arm limiting post 160 abuts against the assist rocker arm 400. The rocker arm limiting post 160, the convex 150, and the limiting hole 420 form a double limiting and locking structure for the assist rocker arm 400.

[0043] In one specific implementation, when the assist rocker arm 400 is rotated to the separation position, the rocker arm limiting post 160 abuts against the assist rocker arm 400 to limit the maximum rotation angle of the assist rocker arm 400 and prevent the assist rocker arm 400 from rotating too much and causing damage to the device.

[0044] like Figure 2-4As shown, this application provides a pull rod assist connector, including a male end 300 and a female end structure of the pull rod assist connector as described in any embodiment of this application; The female end housing 100 is adapted to be inserted into the male end 300. The male end 300 is provided with a male end gear 310, and the assist rocker arm 400 is provided with a rocker arm gear 410 that meshes with the male end gear 310.

[0045] It should be noted that the rotating shaft 130, the rotating shaft hole 430, the rocker gear 410, and the male end gear 310 form a force transmission structure for insertion and extraction. The force of turning the power rocker 400 is transmitted through the meshing force of the rocker gear 410 and the male end gear 310, as well as the force transmission through the hinged rotating shaft 130 and the rotating shaft hole 430, and is converted into a force that drives the female end housing 100 to insert and extract, pressing or separating the female end housing 100 and the male end 300.

[0046] As an example, when the assist rocker arm 400 is pushed upward, the rocker gear 410 rotates downward around the male end gear 310, causing the assist rocker arm 400 to move vertically downward. The assist rocker arm 400 drives the female end housing 100 to move vertically downward and press against the male end 300.

[0047] Although preferred embodiments of the present application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device.
