Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector. Background Art

[0002] A connector is a component that electronic engineering technicians often come into contact with. It is mainly used to connect two active devices to transmit current or signals. Between the blocked parts or isolated circuits in a circuit, the connector can build a communication bridge to make the current flow, so that the circuit can achieve the predetermined function.

[0003] The connector is generally provided with a CPA (Connector Position Assurance) part. The CPA part is a buckle structure used to increase the strength of the connector locking device. The CPA part can effectively protect the reliable connection of the connector plug and socket, and prevent the safety accident of plugging and unplugging under load caused by the accidental loosening or poor contact of the connector.

[0004] In the prior art, the CPA part is generally installed into the connector by inserting from one side of the connector. During the insertion process of the CPA part, it reaches the pre-locking position and the final locking position successively. However, in the prior art, the CPA part will cause wear of the clamping structure due to repeated plugging and unplugging. After long-term use, the CPA part will have poor clamping at the pre-locking position and the final locking position, and the CPA part will become loose, affecting the reliability and stability of the installation of the CPA part. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a connector, which has a simple structure, the installation process of the CPA part is more labor-saving and stable, not easy to loosen, and has strong practicability.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A connector includes a housing, a pull rod and a CPA part. The housing is provided with a plugging groove along a first direction. The CPA part can be plugged into the plugging groove. The pull rod is hinged to the housing;

[0008] A first clamping head is arranged on a first side of the CPA part along a second direction. The housing is correspondingly provided with a clamping groove and a first clamping hole communicating with the plugging groove. The clamping groove and the first clamping hole are arranged in sequence along the insertion direction of the CPA part;

[0009] The pull rod swings to push against the first clamping head to drive the CPA part to be inserted into the plugging groove, so that the CPA part passes through the pre-locking position and the final locking position in sequence; when in the pre-locking position, the first clamping head abuts against the clamping groove; when in the final locking position, the first clamping head is clamped in the first clamping hole;

[0010] The first direction is perpendicular to the second direction.

[0011] Preferably, a second chuck is provided on a second side of the CPA member along the second direction, and a second card hole communicating with the insertion slot is correspondingly provided on the housing;

[0012] When the CPA member is in the pre-locking position, the second chuck is clamped in the second card hole.

[0013] Preferably, a pressing head is provided on the pull rod, and the pressing head is used to push against the first chuck.

[0014] Preferably, the pull rod includes a first rod portion and second rod portions provided in pairs on opposite sides of the first rod portion. The pressing head is provided on the first rod portion. The two second rod portions are correspondingly arranged with opposite sides of the housing along a third direction, and each second rod portion is hinged to the corresponding side of the housing;

[0015] The first direction, the second direction, and the third direction are set to be orthogonal to each other in pairs.

[0016] Preferably, the second rod portion is hinged to the housing through a hinge shaft. The hinge shaft extends along the third direction on the housing. The second rod portion is provided with a hinge hole, and the second rod portion is hinged to the hinge shaft through the hinge hole.

[0017] Preferably, the hinge hole is set as a stepped hole, including a small-end hole portion and a large-end hole portion that are communicated. The hinge shaft passes through the small-end hole portion and extends into the large-end hole portion. A locking groove is provided on the side wall of the small-end hole portion, and the hinge shaft is correspondingly provided with a locking head that can pass through the locking groove.

[0018] Preferably, the housing is provided with a third chuck, and the third chuck is adapted to be clamped to the first rod portion when the CPA member is in the final locking position.

[0020] Preferably, the CPA member includes a main body and an elastic arm provided on the main body, and the first chuck is located on the elastic arm.

[0021] Preferably, the housing includes an upper cover and a housing body. The upper cover is covered on the housing body. The insertion slot is provided on the upper cover, and the pull rod is hingedly arranged on the housing body.

[0022] Beneficial effects:

[0023] The connector provided by the present utility model drives the first chuck by the swing of the pull rod, thereby driving the CPA part to gradually insert into the insertion slot. During this process, the CPA part can pass through the pre-locking position and the final locking position in sequence. Specifically, when the CPA part moves to the pre-locking position, the pull rod pushes against the first chuck and holds the first chuck against the groove wall on the side of the card slot close to the first card hole. As the pull rod further swings, the pull rod continues to push against the first chuck, and then can press the first chuck into the card slot and engage with the first card hole, that is, the CPA part reaches the final locking position. The setting of the pull rod ensures that the insertion of the CPA part is more labor-saving and convenient. And when the CPA part is in the pre-locking position and the final locking position, the pull rod can block the first chuck to prevent the first chuck from loosening, and further prevent the CPA part from falling out of the insertion slot, effectively ensuring the reliability and stability of the installation of the CPA part.

[0040] This embodiment provides a connector. Refer to Figures 1 to 8As shown in the figure, the connector includes a housing 1, a pull rod 2, and a CPA part 3. The housing 1 is provided with a plugging slot 111 along a first direction. The CPA part 3 can be plugged into the plugging slot 111, and the pull rod 2 is hingedly arranged on the housing 1. A first chuck 31 is provided on a first side of the CPA part 3 along a second direction. The housing 1 is correspondingly provided with a card slot 112 and a first card hole 113 that communicate with the plugging slot 111. The card slot 112 and the first card hole 113 are arranged in sequence along the insertion direction of the CPA part 3. The pull rod 2 swings to push against the first chuck 31 to drive the CPA part 3 to be inserted into the plugging slot 111, so that the CPA part 3 passes through a pre-locking position and a final locking position in sequence. When in the pre-locking position, the first chuck 31 abuts against the card slot 112; when in the final locking position, the first chuck 31 is clamped in the first card hole 113. The first direction is perpendicular to the second direction.

[0041] Specifically, the housing 1 includes an upper cover 11 and a housing body 12. The upper cover 11 is covered on the housing body 12. The plugging slot 111 is opened on the upper cover 11, and the pull rod 2 is hingedly arranged on the housing body 12.

[0042] In this embodiment, the direction indicated by a in the attached figure is the first direction, which is the plugging direction of the CPA part 3 relative to the housing 1 and also the opening direction of the plugging slot 111. The direction indicated by b is the second direction, which is a direction perpendicular to the plugging direction of the CPA part 3 and also the height direction of the connector. The upper cover 11 is covered on the housing body 12 along the second direction.

[0043] In this embodiment, by swinging the pull rod 2 to push against the first chuck 31, the CPA part 3 is gradually driven to be inserted into the plugging slot 111. During the process, the CPA part 3 can pass through the pre-locking position and the final locking position in sequence. Specifically, when the CPA part 3 moves to the pre-locking position, the pull rod 2 pushes against the first chuck 31 to abut the first chuck 31 against the groove wall of the card slot 112 on the side close to the first card hole 113. The CPA part 3 being in the pre-locking position corresponds to Figures 4 to 6 as shown. As the pull rod 2 further swings, the pull rod 2 continues to push against the first chuck 31, and then the first chuck 31 can be pressed into the card slot 112 and clamped with the first card hole 113, that is, the CPA part 3 reaches the final locking position. The CPA part 3 being in the pre-locking position corresponds to Figures 7 to 8 as shown. The setting of the pull rod 2 ensures that the insertion of the CPA part 3 is more labor-saving and convenient. And when the CPA part 3 is in the pre-locking position and the final locking position, the pull rod 2 can block the first chuck 31 to prevent the first chuck 31 from loosening, and further prevent the CPA part 3 from falling out of the plugging slot 111, effectively ensuring the reliability and stability of the installation of the CPA part 3.

[0044] Specifically, along the first direction, the card slot 112 and the first card hole 113 are arranged opposite to each other. The first card hole 113 is located on a side farther from the slot opening of the plugging slot 111 than the card slot 112.

[0045] In this embodiment, a second chuck 32 is provided on the second side of the CPA part 3 in the second direction, and the housing 1 is correspondingly provided with a second card hole communicating with the insertion slot 111. When the CPA part 3 is in the pre-locking position, the second chuck 32 is clamped in the second card hole. Specifically, when the CPA part 3 moves to the pre-locking position, while the first chuck 31 abuts against the card slot 112, the second chuck 32 is clamped in the second card hole, further ensuring the reliability and stability of the CPA part 3 in the pre-locking position.

[0046] Specifically, a pressing head 211 is provided on the pull rod 2, and the pressing head 211 is used to push against the first chuck 31.

[0047] Specifically, the pull rod 2 includes a first rod portion 21 and second rod portions 22 provided in pairs on opposite sides of the first rod portion 21. The pressing head 211 is provided on the first rod portion 21. The two second rod portions 22 are correspondingly arranged with the opposite sides of the housing 1 in the third direction, and each second rod portion 22 is hinged to the corresponding side of the housing 1. The first direction, the second direction, and the third direction are orthogonal to each other.

[0048] In this embodiment, the c direction refers to the third direction, and the third direction is the interval direction of the opposite two side walls of the insertion slot 111. Specifically, along the third direction, the number of the first chucks 31 on the CPA part 3 is arranged at intervals, with two or more provided. The number of the card slots 112, the first card holes 113, and the second card holes on the housing 1 is arranged at intervals. The number of the pressing heads 211 on the first rod portion 21 is arranged at intervals. The multiple first chucks 31, card slots 112, first card holes 113, second card holes, and pressing heads 211 are arranged in one-to-one correspondence.

[0049] In this embodiment, the CPA part 3 includes a main body 301 and an elastic arm 302 provided on the main body 301, and the first chuck 31 is located on the elastic arm 302. Specifically, the self-deformation of the elastic arm 302 provides an elastic force, which can ensure that the first chuck 31 can move within a certain range and can be reliably clamped in the card slot 112 or the first card hole 113. Specifically, when the CPA part 3 is in the pre-locking position, as the pull rod 2 further swings, the pull rod 2 continues to push against the first chuck 31, which can cause the elastic arm 302 to deform downward, pressing the first chuck 31 to disengage from the card slot 112 and further move towards the first card hole 113. When the first chuck 31 moves to the first card hole 113, the self-elastic force of the elastic arm 302 drives the first chuck 31 to protrude and be clamped in the first card hole 113.

[0050] Specifically, the main body 301, the elastic arm 302, the first chuck 31, and the second chuck 32 are integrally formed.

[0051] Specifically, a gripping portion 33 is further provided on the main body 301, and the gripping portion 33 can facilitate the operator to take the CPA member 3. The gripping portion 33 is also provided with a pattern structure for increasing friction.

[0052] Specifically, the first rod portion 21 and the second rod portion 22 are integrally formed, which has a simple structure and is easy to process.

[0053] Specifically, the second rod portion 22 is hinged to the housing 1 via a hinge shaft 23, the hinge shaft 23 is extended along the third direction and is disposed on the housing 1, the second rod portion 22 is provided with a hinge hole 221, and the second rod portion 22 is hinged to the hinge shaft 23 via the hinge hole 221. Specifically, the hinge shaft 23 passes through the hinge hole 221 and is rotatably connected to the hinge hole 221.

[0054] More specifically, the hinge hole 221 is configured as a stepped hole, including a small end hole portion 2211 and a large end hole portion 2212 that are connected to each other. The hinge shaft 23 passes through the small end hole portion 2211 and extends into the large end hole portion 2212. The side wall of the small end hole portion 2211 is provided with a locking groove 2213. The hinge shaft 23 is correspondingly provided with a locking head 231 capable of passing through the locking groove 2213. Specifically, when the hinge shaft 23 is rotated to a position where the locking head 231 and the locking groove 2213 overlap, the hinge shaft 23 and the locking head 231 can pass through the small end hole portion 2211 and enter the large end hole portion 2212 together. Then, the hinge shaft 23 is rotated so that the locking head 231 and the locking groove 2213 are offset, and the hinge shaft 23 can be locked in the hinge hole 221 without affecting the rotational cooperation between the hinge shaft 23 and the hinge hole 221.

[0055] In this embodiment, the opening angle of the locking groove 2213 can be set according to actual conditions, and it is only necessary to avoid the corresponding swing range of the pull rod 2 when the CPA is located from the pre-locking position to the final locking position.

[0056] In this embodiment, the housing 1 is provided with a third clamp 114, and the third clamp 114 is suitable for clamping with the first rod portion 21 when the CPA member 3 is in the final locking position. Specifically, by providing the third clamp 114, when the clamping rod swings to a position corresponding to the final locking position of the CPA member 3, the first rod portion 21 and the third clamp 114 are effectively clamped in a straight line, thereby ensuring reliable and effective fixation of the pull rod 2 and ensuring the swing positioning of the pull rod 2.

[0057] In summary, the connector provided in this embodiment has a simple structure, the CPA component 3 is more labor-saving and stable during installation, is not easy to get loose, and is highly practical.

[0058] Obviously, the above-mentioned embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
