Description

Technical Field

[0001] This utility model relates to a connector housing assembly, a connector including the connector housing assembly, and a connector assembly including the connector. Background Technology

[0002] In existing technologies, connector assemblies typically include a connector and a mating connector that mates with the connector. To hold the connector and mating connector in the mating position, a lever-type assist rod is sometimes provided on the connector, which can move between a pre-locked position and a final-locked position. In existing technologies, the assist rod has an elastic locking arm. When the assist rod is in the pre-locked position, this elastic locking arm locks with a corresponding structure on the connector housing to hold the assist rod in the pre-locked position. This causes the assist rod to be subjected to additional compressive force during use, leading to deformation and potential failures such as loosening. Furthermore, when unlocking the assist rod through the mating connector, the operator is unaware of when unlocking is complete, which can easily lead to misoperation. Utility Model Content

[0003] The purpose of this utility model is to solve at least one aspect of the aforementioned problems and defects existing in the prior art.

[0004] According to one aspect of the present invention, a connector housing assembly is provided, comprising: a housing and an assist rod, the housing having an elastic locking structure, the assist rod including a mating locking structure, the assist rod being pivotally connected to the housing and rotatable relative to the housing between a pre-locked position and a final locked position, the elastic locking structure being adapted to move between a locked position engaged with the mating locking structure and an unlocked position disengaged from the mating locking structure; when the assist rod is in the pre-locked position and the elastic locking structure is in the locked position, the assist rod is locked in the pre-locked position by the elastic locking structure to prevent the assist rod from rotating toward the final locked position; when the connector mates with a mating connector, the elastic locking structure is moved to the unlocked position under the pressure of the mating housing of the mating connector to allow the assist rod to rotate toward the final locked position.

[0005] According to an exemplary embodiment of the present invention, the mating locking structure is a groove, which is adapted to engage with the elastic locking structure to prevent the assist rod from rotating toward the final locking position.

[0006] According to another exemplary embodiment of the present invention, the assist rod further includes a pull rod, one end of which is rotatably connected to the housing, and the mating locking structure is disposed on the pull rod.

[0007] According to another exemplary embodiment of the present invention, the pull rod includes: a pair of connecting rods, one end of which is rotatably connected to the outer side of a pair of sidewalls of the housing, the mating locking structure being disposed on at least one of the pair of connecting rods; and a crossbar connected between the other ends of the pair of connecting rods.

[0008] According to another exemplary embodiment of the present invention, a pivot hole is provided at one end of the connecting rod, and a pivot shaft is formed on the outer side of the side wall of the housing. The pivot shaft is fitted into the pivot hole. A radially extending limiting protrusion is formed on the outer end of the pivot shaft to limit the axial position of the assist rod, so as to prevent the assist rod from disengaging from the pivot shaft when the assist rod is rotated.

[0009] According to another exemplary embodiment of the present invention, the elastic locking structure includes: an elastic arm connected to the side wall of the housing; and a first protrusion connected to the elastic arm and protruding outward from the elastic arm; the first protrusion is adapted to engage with the mating locking structure to prevent the assist rod from rotating toward the final locking position.

[0013] According to another exemplary embodiment of the present invention, the third protrusion has a toothed structure, and the distance by which the third protrusion protrudes outward from the elastic arm is less than the distance by which the second protrusion protrudes outward from the elastic arm.

[0014] According to another exemplary embodiment of the present invention, the second protrusion includes a protrusion groove extending through the second protrusion in the direction of the extension of the elastic arm, and the third protrusion is disposed in the protrusion groove.

[0015] According to another exemplary embodiment of the present invention, the mating housing includes a mating protrusion formed on the inner side of the sidewall of the mating housing, adapted to push the second protrusion when the connector and the mating connector are mated together.

[0016] According to another exemplary embodiment of the present invention, the mating housing further includes a protruding rib that protrudes inward from a mating protrusion guide surface toward the opening of the mating housing, and is adapted to abut against the third protrusion.

[0017] According to another exemplary embodiment of the present invention, during the process of the connector and the mating connector engaging with each other: the raised rib abuts against the side of the third protrusion facing the connector mating surface before the mating protrusion of the mating housing moves to the top of the second protrusion; when the mating protrusion of the mating housing moves to the top of the second protrusion, the resilient locking structure is pushed to the unlocked position to allow the raised rib to pass over the third protrusion and abut against the side of the third protrusion away from the connector mating surface, thereby keeping the connector and the mating connector pre-engaged without separating from each other.

[0018] According to another exemplary embodiment of the present invention, the process of the protruding rib passing over the third protrusion will compress the third protrusion to cause it to elastically shift, thereby generating vibration and sound to indicate that the elastic locking structure has been unlocked into place.

[0019] According to another exemplary embodiment of the present invention, the assist rod includes a pull rod, one end of which is rotatably connected to the side wall of the housing; a tooth is formed on one end of the pull rod; a mating tooth is formed on the mating housing, adapted to engage with the tooth; during the rotation of the assist rod from the pre-lock position to the final lock position, the tooth is adapted to push the mating housing from the pre-installed position to the mating position by engaging with the mating tooth; and during the rotation of the assist rod from the final lock position to the pre-lock position, the tooth is adapted to push the mating housing from the mating position to the pre-installed position by engaging with the mating tooth.

[0020] According to another exemplary embodiment of the present invention, the housing is provided with a stop portion, which is adapted to move between a stop position and a non-stop position.

During the process of the assist rod rotating from the pre-lock position to the final lock position, the crossbar inclined surface pushes the stop protrusion, so that the stop part shifts from the stop position to the non-stop position, thereby allowing the assist rod to pass over the stop protrusion and move to the final lock position. When the assist rod is in the final lock position, the crossbar inclined surface no longer pushes the stop protrusion, and the stop part returns from the non-stop position to the stop position, which is suitable for preventing the assist rod from moving to the pre-lock position.

[0023] According to another aspect of the present invention, a connector is provided, comprising: the aforementioned connector housing assembly and a terminal module, wherein the terminal module is disposed in the housing.

[0024] According to another aspect of the present invention, a connector assembly is provided, comprising: the aforementioned connector and a mating connector, the mating connector being adapted to mate with the connector and being movable relative to the connector between a pre-installed position and a mating position, wherein when the connector mates with the mating connector, the terminal module of the connector makes electrical contact with the mating terminals on the mating connector.

[0026] In the foregoing exemplary embodiments of the present invention, the elastic locking structure on the connector housing is adapted to be unlocked under the pushing of the mating housing of the mating connector. During the locking and unlocking process, the assist rod is not squeezed and deformed. Therefore, the assist rod is not subjected to additional squeezing force during use, and is not prone to failure problems such as loosening, thereby enhancing the reliability of the assist rod during use.

[0027] In the foregoing exemplary embodiments of the present invention, the connector housing is further provided with a toothed protrusion structure, which is adapted to generate vibration when the elastic locking structure is pushed to unlock, thereby providing the operator with an unlocking signal such as sound or vibration feeling that the unlocking is complete, so that the operator can proceed with the next step of the connector assembly mating and connection operation, effectively avoiding misoperation due to incomplete unlocking.

[0028] In addition, the toothed protrusions on the connector housing can abut and lock together after being squeezed and offset from the protruding ribs on the mating housing, thereby keeping the connector and mating connector in the pre-installed position and preventing problems such as loosening or separation of the connector components due to operator interruption.

[0029] Furthermore, the connector assembly of this utility model has a simple structure and is easy to install.

In other instances, well-known structures and apparatuses are illustrated to simplify the figures.

[0051] According to a general technical concept of this utility model, a connector housing assembly is provided, comprising: a housing and an assisting rod. The housing is provided with an elastic locking structure, and the assisting rod includes a mating locking structure. The assisting rod is rotatably connected to the housing and is rotatable relative to the housing between a pre-locked position and a final locked position. The elastic locking structure is adapted to move between a locked position engaged with the mating locking structure and an unlocked position disengaged from the mating locking structure. When the assisting rod is in the pre-locked position and the elastic locking structure is in the locked position, the assisting rod is locked in the pre-locked position by the elastic locking structure to prevent the assisting rod from rotating toward the final locked position. When the connector mates with a mating connector, the elastic locking structure is moved to the unlocked position under the pushing force of the mating housing of the mating connector to allow the assisting rod to rotate toward the final locked position.

[0052] According to another general technical concept of the present invention, a connector is provided, comprising: the aforementioned connector housing assembly and a terminal module, wherein the terminal module is disposed in the housing.

[0053] According to another general technical concept of the present invention, a connector assembly is provided, comprising: the aforementioned connector and a mating connector, the mating connector being adapted to mate with the connector and being movable relative to the connector between a pre-installed position and a mating position, wherein when the connector mates with the mating connector, the terminal module of the connector makes electrical contact with the mating terminals on the mating connector.

[0054] Figure 1A This diagram shows a perspective view of a connector assembly according to an exemplary embodiment of the present invention, wherein the connector and the mating connector are in a pre-assembled position; Figure 1B show Figure 1A The exploded 3D view of the connector assembly is shown.

[0055] like Figure 1A and Figure 1B As shown in the illustrated embodiment, the connector assembly mainly includes a connector 100 and a mating connector 20 adapted to mate with the connector 100.

The resilient locking structure 102 is adapted to move between a locked position engaged with the mating locking structure 122 and an unlocked position disengaged from the mating locking structure 122. When the assist rod 120 is in the pre-locked position and the resilient locking structure 102 is in the locked position, the assist rod 120 is locked in the pre-locked position by the resilient locking structure 102 to prevent the assist rod 120 from rotating toward the final-locked position. When connector 10 mates with mating connector 20, the resilient locking structure 102 is moved to the unlocked position under the pressure of the mating housing 200 of mating connector 20 to allow the assist rod 120 to rotate toward the final-locked position.

[0059] like Figures 1A to 4 As shown in the illustrated embodiment, the terminal module 110 is disposed in the housing 100, and the mating connector 20 is provided with mating terminals 210.

A radially extending limiting protrusion 108 is formed on the outer end of the pivot shafts 106a and 106b to limit the axial position of the assist rod 120, so as to prevent the assist rod 120 from disengaging from the pivot shafts 106a and 106b when the assist rod 120 is rotated.

[0065] like Figures 1A to 4 As shown in the illustrated embodiment, the resilient locking structure 102 includes a resilient arm 111, a first protrusion 112, a second protrusion 114, and a third protrusion 116. The resilient arm 111 is connected to the side wall 104 of the housing 100, and the first protrusion is connected to and protrudes outward from the resilient arm 111. The first protrusion 112 is adapted to engage with the mating locking structure 122 to prevent the assist rod 120 from rotating toward the final locked position.

[0066] like Figures 1A to 4 As shown in the illustrated embodiment, a second protrusion 114 is connected to and protrudes outward from the elastic arm 111. The second protrusion 114 is adapted to be pushed by the mating housing 200, causing the elastic locking structure 102 to move from a locked position to an unlocked position in a direction toward the housing 100. The second protrusion 114 extends a first predetermined length on the elastic arm 111 and has inclined protruding guide surfaces 114a and 114b formed at its two ends to guide the mating housing 200 to move onto the top 114c of the second protrusion 114, so that the mating housing 200 applies a pushing force to the second protrusion 114.

[0067] like Figures 1A to 4 As shown in the illustrated embodiment, the third protrusion 116 is connected to and protrudes outward from the elastic arm 111. In the direction extending transversely to the elastic arm 111, the third protrusion 116 is arranged side by side with the top 114c of the second protrusion 114, and the second predetermined length of the third protrusion 116 extending on the elastic arm 111 is less than the first predetermined length of the second protrusion 114 extending on the elastic arm 111.

[0068] like Figures 1A to 4As shown in the illustrated embodiment, the third protrusion 116 has a toothed structure, and the distance by which the third protrusion 116 protrudes outward from the elastic arm 111 is less than the distance by which the second protrusion 114 protrudes outward from the elastic arm 111.

[0069] like Figures 1A to 4 As shown in the illustrated embodiment, the second protrusion 114 includes a protrusion groove 117, which passes through the second protrusion 114 in the direction extending along the elastic arm 111. A third protrusion 116 is disposed in the protrusion groove 117.

[0070] like Figures 1A to 4 As shown in the illustrated embodiment, the mating housing 200 includes a mating protrusion 202 formed on the inner side of the sidewall 204 of the mating housing 200. The mating protrusion 202 is adapted to push against the second protrusion 114 when the connector 10 and the mating connector 20 are mated together. The mating protrusion 202 has inclined mating protrusion guide surfaces 214a and 214b formed at its two ends, respectively, adapted to push against the protrusion guide surfaces 114a and 114b of the second protrusion 114 to push the resilient locking structure 102 to the unlocked position.

[0071] like Figures 1A to 4 As shown in the illustrated embodiment, the mating housing 200 further includes a raised rib 212, which protrudes inward from the mating raised guide surfaces 214a, 214b toward a mating raised guide surface of the mating housing opening 201, and is adapted to abut against the third raised portion 116.

[0072] like Figures 1A to 4 As shown in the illustrated embodiment, the housing 100 is provided with a stop portion 118, which is adapted to move between a stopped position and a non-stopped position. When the stop portion 118 is in the stopped position, the stop portion 118 is adapted to block the movement of the assist rod 120; when the stop portion 118 is in the non-stopped position, the stop portion 118 is adapted not to block the movement of the assist rod 120.

[0073] like Figures 1A to 4 As shown in the illustrated embodiment, the stop portion 118 includes a stop arm 118a and a stop protrusion 118b.

[0074] like Figures 1A to 4 As shown in the illustrated embodiment, the inner side of the crossbar 124c of the assist rod 120 is provided with a crossbar inclined surface 128.

[0075] Figure 5AShowing a side view of a connector assembly according to an exemplary embodiment of the present invention, wherein the connector and mating connector are in a separated position, the resilient locking structure is in a locked position, and the booster rod is in a pre-locked position; Figure 5B show Figure 5A The connector assembly shown is a cross-sectional view obtained along the section line CC. Figure 6A Showing a side view of a connector assembly according to an exemplary embodiment of the present invention, wherein the connector and mating connector are in a pre-installed position, the resilient locking structure is in an unlocked position, and the assist rod is in a pre-locked position; Figure 6B show Figure 5A The connector assembly shown is a cross-sectional view obtained along section line D1-D1; Figure 6C show Figure 5A The connector assembly shown is a cross-sectional view obtained along the section line D2-D2; Figure 7A Showing a side view of a connector assembly according to an exemplary embodiment of the present invention, wherein the connector and mating connector are in the mating position and the booster rod is in the final locking position; Figure 7B show Figure 7A The connector assembly shown is a cross-sectional view obtained along the section line EE.

[0076] As shown in Figures 1 to 6, in the illustrated embodiments, when the assist rod 120 is in the pre-locked position and the mating connector 20 is in the pre-installed position, the elastic locking structure 102 is pushed to the unlocked position by the mating housing 200 of the mating connector 20, allowing the assist rod 120 to rotate from the pre-locked position to the final locked position. When the assist rod 120 is rotated from the pre-locked position to the final locked position, the assist rod 120 drives the mating connector 20 from the pre-installed position to the mating position.

[0077] As shown in Figures 1 to 6, in the illustrated embodiment, during the mating of connector 10 and mating connector 20, the raised rib 212 abuts against the side of the third protrusion 116 facing the connector mating surface before the mating protrusion 202 of the mating housing 200 moves to the top 114c of the second protrusion 114. When the mating protrusion 202 of the mating housing 200 moves to the top 114c of the second protrusion 114, the resilient locking structure 102 is pushed to the unlocked position, allowing the raised rib 212 to pass over the third protrusion 116 and abut against the side of the third protrusion 116 away from the connector mating surface, thereby maintaining the pre-engaged connection of connector 10 and mating connector 20 without separation.

[0078] As shown in Figures 1 to 6, in the illustrated embodiment, the process of the protruding rib 212 passing over the third protrusion 116 will compress the third protrusion 116 to cause it to elastically deflect, thereby generating vibration and sound to indicate that the elastic locking structure 102 has been unlocked into place.

[0079] As shown in Figures 1 to 6, in the illustrated embodiments, during the rotation of the assist rod 120 from the pre-lock position to the final lock position, the tooth 130 is adapted to push the mating housing 200 from the pre-installed position to the mating position by engaging with the mating tooth 230. During the rotation of the assist rod 120 from the final lock position to the pre-lock position, the tooth 130 is adapted to push the mating housing 200 from the mating position to the pre-installed position by engaging with the mating tooth 230.

[0080] As shown in Figures 1 to 6, in the illustrated embodiment, during the rotation of the assist rod 120 from the pre-lock position to the final lock position, the crossbar inclined surface 128 pushes against the stop protrusion 118b, causing the stop portion 118 to shift from the stop position to the non-stop position, thereby allowing the assist rod 120 to pass over the stop protrusion 118b and move to the final lock position. When the assist rod 120 is in the final lock position, the crossbar inclined surface 128 no longer pushes against the stop protrusion 118b, and the stop portion 118 returns from the non-stop position to the stop position, suitable for preventing the assist rod 120 from moving towards the pre-lock position.

[0081] Those skilled in the art will understand that the embodiments described above are exemplary and can be improved upon.
