Description

connector

[0001] The present invention relates to a connector, and more specifically, to a connector having a structure that can improve high-current transmission performance and reinforce rigidity.

[0002] Recently, driven by the trend of miniaturization in electronic devices, circuit boards and connectors designed to electrically connect them to other components are also becoming smaller. Conversely, as the amount of information processed by electronic devices increases, the number of terminals provided on circuit boards or connectors is on the rise. Consequently, there is a growing demand for miniaturized connectors.

[0003] Typically, a connector may include a configuration for transmitting electrical signals. In this case, the configuration for transmitting electrical signals may be defined as a contact. The contact may be supported by an insulating material referred to as an insulator or an insulating material.

[0004] Meanwhile, the insulating material may be formed to have low rigidity due to its material. Therefore, when the connector is coupled with the mating connector, if the direction or angle is misaligned, there is a risk that the insulating material may be damaged by the external force applied to the connector. Accordingly, the connector includes another configuration named a hold-down to reinforce the rigidity of the insulating material.

[0005] The hold-down is formed from a metal material and combined with an insulating material to reinforce the rigidity of the insulating material. Additionally, since the hold-down is formed from a metal material, it can also perform the role of transmitting power for the operation of the connector.

[0006] In this case, the hold-down can transmit power of various sizes. As the power requirements of electronic devices utilizing connectors have recently increased, there is a growing number of instances where the hold-down takes on the role of transmitting high current.

[0007] Meanwhile, for high current to be transmitted, the number of points where the hold-downs provided in each connector are connected to each other must be increased compared to the case where low current is transmitted.

[0008] However, in the case of a hold-down according to the conventional technology, only the hold-down provided in one connector is configured to enable elastic connection, while the hold-down provided in another connector is configured to enable only fixed connection. Consequently, the increase in the number of points where each hold-down connects to one another is limited, which presents difficulties in high-current transmission.

[0009] Furthermore, the hold-down provided in any one of the above-mentioned connectors is configured to include both a configuration for fixed connection and a configuration for elastic connection. In this case, a cut-out portion must be formed inside the hold-down to secure space for the elastic connection. Consequently, the overall rigidity of the hold-down is reduced, and there is a problem with the difficulty of processing.

[0075]

[0076] Referring to FIGS. 1 and FIGS. 19, a plug connector (10) and a receptacle connector (20) constituting a connector (1) according to an embodiment of the present invention are illustrated as examples. The connector (1) according to the illustrated embodiment may be configured to include a plug connector (10) and a receptacle connector (20).

[0077] The plug connector (10) and the receptacle connector (20) can each be combined with different electrical devices (not shown) and electrically connected. Additionally, the plug connector (10) and the receptacle connector (20) can be combined with each other and electrically connected. Accordingly, different electrical devices (not shown) combined with the plug connector (10) and the receptacle connector (20), respectively, can be electrically connected with each other.

[0078] In one embodiment, the plug connector (10) and the receptacle connector (20) may be mounted on a substrate, for example, a PCB (Printed Circuit Board), each provided in the electrical device (not shown). In the above embodiment, the connector (1) may be referred to as a B2B (Board to Board) connector.

[0079] Meanwhile, the plug connector (10) and the receptacle connector (20) of the connector (1) according to an embodiment of the present invention may be configured to transmit a high current. To this end, the power transmission configurations provided in the plug connector (10) and the receptacle connector (20), respectively (i.e., the plug hold-down (300), the receptacle fixed hold-down (600), and the receptacle movable hold-down (700) to be described later) may be configured to be elastically deformable.

[0080] Additionally, the configurations (plug hold-down (300), receptacle fixed hold-down (600), receptacle movable hold-down (700)) provided in the plug connector (10) and the receptacle connector (20), respectively, can be electrically connected at multiple points. In other words, the plug connector (10) and the receptacle connector (20) can be electrically connected at multiple points to transmit power.

[0081] Therefore, compared to the case where the plug connector (10) and the receptacle connector (20) transmit power at a single connection point, a larger current, i.e., a high current, can be transmitted.

[0082] Meanwhile, in the case of the receptacle connector (20) to be described later, the configuration for transmitting power may include a configuration in which a fixed connection is made (i.e., a receptacle fixed hold-down (600)) and a configuration in which a connection is made by elastic deformation (i.e., a receptacle movable hold-down (700)). At this time, the receptacle fixed hold-down (600) and the receptacle movable hold-down (700) may be physically separated from each other and provided separately.

[0083] Therefore, when the receptacle fixed hold-down (600) and the receptacle movable hold-down (700) are composed of a single member, additional incisions for elastic deformation are not required. Accordingly, the receptacle fixed hold-down (600) and the receptacle movable hold-down (700) can be easily manufactured, and the rigidity of the receptacle fixed hold-down (600) and the receptacle movable hold-down (700) can also be sufficiently secured.

[0084] Below, the structure and function of the plug connector (10), the structure and function of the receptacle connector (20), and the combined structure of the plug connector (10) and the receptacle connector (20) will be explained in order.

[0085]

[0086] Referring to FIGS. 1 to 18, a plug connector (10) according to an embodiment of the present invention is illustrated as an example. The plug connector (10) according to the illustrated embodiment may be mounted on a substrate provided in an external electrical device (not shown). Accordingly, the plug connector (10) may be said to constitute a part of the connector (1) provided as a B2B connector.

[0087] The plug connector (10) is combined with the receptacle connector (20) and electrically connected. At this time, the plug connector (10) may be configured to transmit signals and power to the receptacle connector (20). To this end, the plug connector (10) may be configured to include a configuration for signal transmission (i.e., a plug signal contact (210) to be described later) and a configuration for power transmission (i.e., a plug power contact (220) and a plug hold-down (300) to be described later).

[0088] The plug connector (10) may have a shape corresponding to the shape of the receptacle connector (20). In the illustrated embodiment, the plug connector (10) is formed such that its length in the X-axis direction is longer than its width in the Y-axis direction and its height in the Z-axis direction. The plug connector (10) can be moved in the Z-axis direction to be coupled with the receptacle connector (20).

[0089] In the illustrated embodiment, the plug connector (10) includes a plug insulator (100), a plug contact (200), and a plug hold-down (300).

[0090] The plug insulator (100) is combined with other components of the plug connector (10) and supports them. The plug insulator (100) may be configured to block electrical connections between other components of the combined plug connector (10). To this end, the plug insulator (100) may be formed of an electrically insulating material.

[0091] The plug insulator (100) is coupled with the plug contact (200). The plug contact (200) can be electrically connected to the receptacle connector (20) while coupled with the plug insulator (100).

[0092] The plug insulator (100) is coupled with the plug hold-down (300). Each side of the plug insulator (100) in the X-axis direction, the left and right sides in the illustrated embodiment, can be coupled with the plug hold-down (300). The plug insulator (100), which has relatively low rigidity due to its material, can have its rigidity reinforced by the plug hold-down (300).

[0093] At this time, the plug insulator (100) can electrically insulate each component of the plug contact (200) and the plug contact (200) and the plug holddown (300).

[0094] In the embodiments illustrated in FIGS. 4 to 9, the plug insulator (100) includes a plug insulating body (110), a plug island receiving portion (120), a plug contact coupling portion (130), a plug hold-down coupling portion (140), a plug mounting space (150), a plug receiving space (160), and a plug operating space (170).

[0095] The plug insulating body (110) constitutes the body of the plug insulator (100). Other components of the plug insulator (100) may be formed or combined in the plug insulating body (110). In the illustrated embodiment, a plug island receiving portion (120) is formed inside the plug insulating body (110). Each side in the Y-axis direction of the plug insulating body (110), the front side and the rear side in the illustrated embodiment, may be defined as a plug contact coupling portion (130).

[0096] Each side in the X-axis direction of the plug insulating body (110), the left and right sides in the illustrated embodiment, may be defined as a plug hold-down coupling part (140). A plug mounting space (150) is formed on the other side in the Z-axis direction of the plug hold-down coupling part (140) of the plug insulating body (110), the lower side in the illustrated embodiment.

[0097] A portion of the lower side in the illustrated embodiment, which is the other side in the Z-axis direction of the plug insulating body (110), may surround the plug receiving space (160). Additionally, a plug operating space (170) is formed along the Y-axis direction of a portion of the lower side in the illustrated embodiment, which is the other side in the Z-axis direction of the plug insulating body (110), to surround the plug receiving space (160).

[0098] The plug insulating body (110) may have a shape corresponding to the shape of the plug connector (10). In the illustrated embodiment, the plug insulating body (110) is a three-dimensional shape having a length in the X-axis direction longer than the width in the Y-axis direction and a height in the Z-axis direction.

[0099] The plug island receiving portion (120) is a space formed inside the plug insulating body (110). The plug island receiving portion (120) accommodates a receptacle insulating island (420) provided in a receptacle connector (20) coupled with a plug connector (10). A receptacle contact (500) located adjacent to the receptacle insulating island (420) can be electrically connected to a plug contact (200) exposed to the plug island receiving portion (120).

[0100] The plug island receiving portion (120) may be defined by being surrounded by each part of the plug insulating body (110). In the illustrated embodiment, each side in the X-axis direction, each side in the Y-axis direction, and one side in the Z-axis direction of the plug island receiving portion (120) are surrounded by the plug insulating body (110).

[0101] The other side in the Z-axis direction of the plug island receiving portion (120), the upper side in the illustrated embodiment, is formed open. The receptacle insulating island (420) of the receptacle connector (20) can be inserted through the upper side of the plug island receiving portion (120).

[0102] The plug island receiving portion (120) is in communication with the plug contact coupling portion (130). The plug contact (200) received in the plug contact coupling portion (130) may be at least partially exposed to the plug island receiving portion (120). In the illustrated embodiment, each side of the plug island receiving portion (120) in the Y-axis direction is in communication with the plug contact coupling portion (130).

[0103] The plug island receiving portion (120) may have a shape corresponding to the shape of the plug insulating body (110) or the receptacle insulating island (420). In the illustrated embodiment, the plug island receiving portion (120) is a three-dimensional shape having a length in the X-axis direction longer than the width in the Y-axis direction and a height in the Z-axis direction.

[0104] The plug contact coupling portion (130) is a configuration in which the plug insulator (100) is coupled to the plug contact (200). The plug contact (200) is received in the plug contact coupling portion (130) and can be supported by other configurations of the plug insulator (100).

[0105] A plug contact coupling portion (130) is formed on an outer corner of the plug insulating body (110). In the illustrated embodiment, the plug contact coupling portion (130) is formed by being recessed at each corner in the Y-axis direction of the plug insulating body (110) (i.e., the portion extending in the X-axis direction). That is, the plug contact coupling portions (130) formed at each corner of the plug insulating body (110) are positioned facing each other along the Y-axis direction with the plug island receiving portion (120) in between.

[0106] The plug contact coupling portion (130) is in communication with the outside of the plug insulator (100) and the plug island receiving portion (120), respectively. The plug contact (200) received in the plug contact coupling portion (130) is exposed to the outside of the plug insulator (100) and the plug island receiving portion (120), respectively, and can be electrically connected to the receptacle contact (500) provided in the receptacle connector (20).

[0107] Multiple plug contact coupling portions (130) may be formed. Each of the multiple plug contact coupling portions (130) may accommodate multiple plug contacts (200). The multiple plug contact coupling portions (130) may be spaced apart along the X-axis direction.

[0108] In the illustrated embodiment, the plug contact coupling portion (130) includes a plug signal contact coupling portion (131) and a plug power contact coupling portion (132).

[0109] The plug signal contact coupling portion (131) accommodates the plug signal contact (210) of the plug contact (200). The plug signal contact (210) accommodated in the plug signal contact coupling portion (131) is exposed to the outside of the plug insulator (100) and the plug island receiving portion (120) so as to be electrically connected to the receptacle signal contact (510).

[0110] The plug signal contact coupling portion (131) is formed by being recessed at each corner of the plug insulating body (110). At this time, the plug signal contact coupling portion (131) is formed by being recessed at each side in the Y-axis direction and one side in the Z-axis direction of each corner of the plug insulating body (110).

[0111] Multiple plug signal contact coupling portions (131) may be formed. Multiple plug signal contact coupling portions (131) may be spaced apart from each other to accommodate multiple plug signal contacts (210) respectively.

[0112] At this time, the remaining portion of the corner of the plug insulating body (110) is located between the plurality of plug signal contact joints (131). That is, the plurality of plug signal contact joints (131) can be physically and electrically partitioned by the remaining portion.

[0113] Accordingly, a plurality of plug signal contacts (210) each accommodated in a plurality of plug signal contact coupling portions (131) can be electrically insulated from each other.

[0114] In the illustrated embodiment, the plug signal contact coupling portions (131) are provided in pairs, each comprising three. The three plug signal contact coupling portions (131) are spaced apart along the X-axis direction and are located between a pair of plug power contact coupling portions (132).

[0115] The plug power contact coupling portion (132) accommodates the plug power contact (220) of the plug contact (200). The plug power contact (220) accommodated in the plug power contact coupling portion (132) is exposed to the outside of the plug insulator (100) and the plug island receiving portion (120), so that it can be electrically connected to the receptacle power contact (520).

[0116] The plug power contact coupling portion (132) is formed by being recessed at each corner of the plug insulating body (110). At this time, the plug power contact coupling portion (132) is formed by being recessed at each side in the Y-axis direction and one side in the Z-axis direction of each corner of the plug insulating body (110).

[0117] Multiple plug power contact coupling portions (132) may be formed. Multiple plug power contact coupling portions (132) may be spaced apart from each other to accommodate multiple plug power contacts (220) respectively.

[0118] At this time, the remaining portion of the corner of the plug insulating body (110) is located between the plurality of plug power contact joints (132). That is, the plurality of plug power contact joints (132) can be physically and electrically partitioned by the remaining portion.

[0119] Accordingly, a plurality of plug power contacts (220) each accommodated in a plurality of plug power contact coupling portions (132) can be electrically insulated from each other.

[0120] In the illustrated embodiment, the plug power contact coupling portions (132) are provided as a pair, each comprising two. The two plug power contact coupling portions (132) are spaced apart along the X-axis direction and positioned facing each other with three plug signal contact coupling portions (131) located between them.

[0121] The plug hold-down coupling portion (140) is a configuration in which the plug insulator (100) is coupled with the plug hold-down (300) to support it. The plug hold-down coupling portion (140) can be defined as an end portion in the X-axis direction of the plug insulator body (110). Multiple plug hold-down coupling portions (140) may be defined, and each of the multiple plug hold-down coupling portions (140) can support multiple plug hold-downs (300).

[0122] In the illustrated embodiment, the plug hold-down coupling portions (140) are defined as a pair by each side end in the X-axis direction of the plug insulator (100). The pair of plug hold-down coupling portions (140) are positioned facing each other along the X-axis direction with the plug island receiving portion (120) in between. A pair of plug hold-downs (300) can be coupled and supported in each plug hold-down coupling portion (140).

[0123] Accordingly, the plug insulator (100) made of an insulating material having relatively low rigidity can have its rigidity reinforced by the plug holddown (300). Accordingly, when the plug connector (10) and the receptacle connector (20) are combined, damage to the plug insulator (100) can be prevented.

[0124] Meanwhile, a pair of plug hold-down coupling parts (140) spaced apart along the X-axis direction are formed symmetrically with respect to the Y-axis direction. Below, the explanation will focus on the plug hold-down coupling part (140) located on one side of the X-axis direction, that is, on the left side.
