Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an installation structure of a protection plate and a housing and a connector. Background Technique

[0002] An electronic connector is also often referred to as a circuit connector or an electrical connector, which bridges two conductors on a loop so that current or signals can flow from one conductor to another conductor device.

[0003] In an electronic connector, a protection plate is provided. The protection plate is used to protect the joint terminals during the connection and separation of the connector, and also facilitates the connection and separation.

[0004] Currently, the protection plate is installed in the housing of the electronic connector. A buckle structure is provided inside the housing to fix the protection plate. Every time the terminals or wire harnesses need to be adjusted, the protection plate needs to be removed from the housing. This split state is likely to cause the loss of the protection plate.

[0005] Moreover, when pressing the protection plate against the housing, due to uneven application of force, the protection plate tilts inside the housing or even gets stuck inside the housing, which is not convenient for removal and is likely to cause extrusion damage to the terminals.

[0006] Therefore, there is an urgent need for an installation structure of a protection plate and a housing and a connector to solve the above technical problems. Content of the Utility Model

[0007] The purpose of the utility model is to provide an installation structure of a protection plate and a housing and a connector, which can enable the protection plate to have a pre-locking position and a final locking position, without the need to be separated from the housing, and can standardize the movement path of the protection plate relative to the first housing to avoid tilting.

[0008] To achieve this purpose, the utility model adopts the following technical solutions:

Limit plates are respectively fixed on opposite sides of the protection plate, and the limit plates can be attached to and slide relative to the inner peripheral wall of the inner cavity.

[0013] As a preferred technical solution of the installation structure of the protection plate and the housing, at least two groups of the above-mentioned clamping block groups are arranged at intervals along the second direction on the same side wall of the inner cavity, and the protection plate can be clamped with at least two groups of the above-mentioned clamping block groups on the same side wall;

[0014] The first direction is perpendicular to the second direction.

[0015] As a preferred technical solution of the installation structure of the protection plate and the housing, on the same side wall of the inner cavity, a limiting groove is formed between two adjacent clamping block groups in the second direction, and the limit plate is slidably arranged in the limiting groove along the first direction.

[0016] As a preferred technical solution of the installation structure of the protection plate and the housing, the protection plate is provided with an avoidance hole.

[0017] As a preferred technical solution of the installation structure of the protection plate and the housing, a first guiding surface is arranged on the side of the first clamping block facing away from the second clamping block, and the first guiding surface inclines towards the bottom wall of the inner cavity on the side away from the peripheral side wall of the inner cavity.

[0018] As a preferred technical solution of the installation structure of the protection plate and the housing, a second guiding surface is formed on the side of the second clamping block facing the first clamping block, and the second guiding surface inclines towards the bottom wall of the inner cavity on the side away from the peripheral side wall of the inner cavity.

[0019] As a preferred technical solution of the installation structure of the protection plate and the housing, a third guiding surface is formed on the side of the second clamping block facing away from the first clamping block, and the third guiding surface inclines towards the first clamping block on the side away from the peripheral side wall of the inner cavity.

[0020] As a preferred technical solution of the installation structure of the protection plate and the housing, a sliding groove is arranged on one of the inner cavity side wall of the first housing and the outer peripheral wall of the second housing, and a sliding block is arranged on the other, and the sliding block can be slidably inserted into the sliding groove.

[0022] A connector is also provided, which includes the above-mentioned protection plate and housing mounting structure.

[0023] Advantages of the present utility model:

[0024] The present utility model provides a protection plate and housing mounting structure, which includes a first housing, a second housing, and a protection plate. The first housing is provided with an inner cavity, and a set of clamping blocks is convexly provided on the inner peripheral wall of the inner cavity. The set of clamping blocks includes a first clamping block and a second clamping block. Along a first direction, the opening of the inner cavity, the first clamping block, and the second clamping block are sequentially arranged at intervals. At least two sets of clamping blocks are provided, and are respectively located on opposite side walls of the inner cavity; the second housing is inserted into the first housing, and the first clamping block, the second clamping block, and the second housing are sequentially arranged at intervals along the first direction; the protection plate can be slidably inserted into the inner cavity along the first direction, and the protection plate can selectively be located between the first clamping block and the second clamping block and supported by the second clamping block, or, located between the second clamping block and the second housing and supported by the end face of the second housing. Limiting plates are respectively fixed on opposite sides of the protection plate, and the limiting plates can be attached to and relatively slide with the inner peripheral wall of the inner cavity.

[0025] The first direction is the axial direction of the inner cavity. Along the first direction, the groove formed between the first clamping block and the second clamping block is the pre-locking position of the protection plate, and the groove formed between the second clamping block and the second housing is the final-locking position of the protection plate. When in the pre-locking position, the protection plate is supported by the second clamping block, and the first clamping block is used to limit the protection plate from exiting the pre-locking position towards the opening direction of the inner cavity; when in the final-locking position, the protection plate directly abuts against the end face of the second housing, and the second clamping block is used to limit the protection plate from retracting from the final-locking position to the pre-locking position. Since the protection plate generally needs to rely on external force when switching between the pre-locking position and the final-locking position, but when the acting point of the external force deviates, it is easy to cause the protection plate to tilt in the inner cavity or even get stuck in the inner cavity. Therefore, in this embodiment, the protection plate is provided with limiting plates, and the limiting plates can be attached to and relatively slide with the inner peripheral wall of the inner cavity, and are used to straighten the protection plate. When the protection plate is acted on by an external force and switches between the pre-locking position and the final-locking position, the limiting plates make the forces on opposite sides of the protection plate balanced and limit the protection plate, thereby standardizing the movement path of the protection plate relative to the first housing.

[0046] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0047] Such as Figures 1 to 11As shown in the figure, the present utility model provides an installation structure of a protection plate and a housing, including a first housing 10, a second housing 20, and a protection plate 30. The first housing 10 is provided with an inner cavity 11, and a set of clamping blocks is convexly provided on the inner peripheral wall of the inner cavity 11. The set of clamping blocks includes a first clamping block 12 and a second clamping block 13. Along the first direction X, the opening of the inner cavity 11, the first clamping block 12, and the second clamping block 13 are sequentially arranged at intervals. At least two sets of clamping blocks are provided, which are respectively located on the opposite side walls of the inner cavity 11; the second housing 20 is inserted into the first housing 10, and the first clamping block 12, the second clamping block 13, and the second housing 20 are sequentially arranged at intervals along the first direction X; the protection plate 30 can be slidably inserted into the inner cavity 11 along the first direction X. The protection plate 30 can be selectively located between the first clamping block 12 and the second clamping block 13 and supported by the second clamping block 13, or located between the second clamping block 13 and the second housing 20 and supported by the end face of the second housing 20. Limited plates 31 are respectively fixed on the opposite sides of the protection plate 30, and the limited plates 31 can be attached to and relatively slide along the inner peripheral wall of the inner cavity 11.

[0048] Exemplarily, the first direction X is the axial direction of the inner cavity 11. Along the first direction X, the groove formed between the first clamping block 12 and the second clamping block 13 is the pre-locking position of the protection plate 30, and the groove formed between the second clamping block 13 and the second housing 20 is the final locking position of the protection plate 30. When in the pre-locking position, the protection plate 30 is supported by the second clamping block 13, and the first clamping block 12 is used to limit the protection plate 30 from exiting the inner cavity 11 in the direction of the opening of the inner cavity 11; when in the final locking position, the protection plate 30 directly abuts against the end face of the second housing 20, and the second clamping block 13 is used to limit the protection plate 30 from retracting from the final locking position to the pre-locking position. Since the protection plate 30 generally needs to rely on external force when switching between the pre-locking position and the final locking position, but when the acting point of the external force is offset, it is easy to cause the protection plate 30 to tilt in the inner cavity 11 or even get stuck in the inner cavity 11. Therefore, in this embodiment, the protection plate 30 is provided with limited plates 31, and the limited plates 31 can be attached to and relatively slide along the inner peripheral wall of the inner cavity 11, which is used to straighten the protection plate 30. When the protection plate 30 is acted on by an external force and switches between the pre-locking position and the final locking position, the limited plates 31 make the forces on the opposite sides of the protection plate 30 balanced and limit the protection plate 30, thereby standardizing the moving path of the protection plate 30 relative to the first housing 10.

[0049] It should be noted that the set of clamping blocks and / or the protection plate 30 can undergo elastic deformation. In this way, when pressing the protection plate 30 along the first direction X, the protection plate 30 can pass through the first clamping block 12 or the second clamping block 13.

[0050] Optionally, at least two sets of latch groups are provided at intervals along the second direction Y on the same side wall of the inner cavity 11, and the protection plate 30 can be latched with at least two sets of latch groups on the same side wall; the first direction X is perpendicular to the second direction Y. In this way, by adding several latch groups in the second direction Y, more support can be provided for the protection plate 30, so that the protection plate 30 is placed more stably in the inner cavity 11 of the first housing 10.

[0051] Optionally, on the same side wall of the inner cavity 11, a limiting groove is formed between two adjacent latch groups in the second direction Y, and the limiting plate 31 is slidably arranged in the limiting groove along the first direction X. In this way, the limiting plate 31 of the protection plate 30 is clamped between two latch groups, which can standardize the movement track of the protection plate 30 relative to the first housing 10 along the first direction X. Avoid the protection plate 30 tilting in the inner cavity 11 during movement due to uneven force or other reasons.

[0052] Optionally, the protection plate 30 is provided with an avoidance hole 32. The staff can insert a hook-shaped tool into the avoidance hole 32 to pull the protection plate 30 towards the outlet of the inner cavity 11 of the first housing 10, which is convenient for taking it out.

[0053] Optionally, a first guiding surface 121 is provided on the side of the first latch 12 facing away from the second latch 13, and the first guiding surface 121 inclines towards the bottom wall of the inner cavity 11 on the side away from the peripheral side wall of the inner cavity 11. In this way, when installing the protection plate 30 into the inner cavity 11, the first guiding surface 121 can make it easier for the protection plate 30 to cross over the first latch 12 and enter between the first latch 12 and the second latch 13 to reach the pre-locked position.

[0054] Optionally, a second guiding surface 131 is formed on the side of the second latch 13 facing the first latch 12, and the second guiding surface 131 inclines towards the bottom wall of the inner cavity 11 on the side away from the peripheral side wall of the inner cavity 11. In this way, when the protection plate 30 moves from the pre-locked position to the final locked position, the second guiding surface 131 can make it easier for the protection plate 30 to cross over the second latch 13 and enter between the second latch 13 and the second housing 20 to reach the final locked position.

[0055] Optionally, a third guiding surface 132 is formed on the side of the second latch 13 facing away from the first latch 12, and the third guiding surface 132 inclines towards the first latch 12 on the side away from the peripheral side wall of the inner cavity 11. In this way, when the protection plate 30 retreats from the final locked position to the pre-locked position, the third guiding surface 132 can make it easier for the protection plate 30 to cross over the second latch 13 and enter between the first latch 12 and the second latch 13 to reach the pre-locked position.

[0056] Optionally, a sliding groove 21 is provided on one of the side walls of the inner cavity 11 of the first housing 10 and the outer peripheral wall of the second housing 20, and a sliding block is provided on the other. The sliding block can be slidably inserted into the sliding groove 21. In this way, by the limitation of the sliding block and the sliding groove 21, the movement route of the second housing 20 relative to the first housing 10 is standardized.

[0057] Optionally, the second housing 20 is provided with a positioning block 22 protruding therefrom. The positioning block 22 can be inserted into the protection plate 30 along the first direction X. During assembly, the second housing 20 is first installed in the first housing 10 before the mounting plate. After the positioning block 22 of the second housing 20 is inserted into the protection plate 30, it plays a role in auxiliary limitation to ensure the relative position between the protection plate 30 and the second housing 20.

[0058] A connector is also provided, including the above protection plate and housing mounting structure.

[0059] In addition, the above is only the preferred embodiment of the present invention and the applied technical principles. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described here. Various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments.
