Description

Plug connector for floating B2B connector {plug connector for floating board to board connector}

The present application relates to a plug connector, and more specifically, to a plug connector that can be used as a floating B2B (board to board) connector.

Board-to-board connectors are used to connect printed circuit boards (PCBs) or electronic components with patterned conductors. In particular, board-to-board connectors (B2B connectors) include plug connectors and receptacle connectors, each of which is connected to a different board, and by combining the plug connector and the receptacle connector, signal transmission through different boards can be enabled.

In the past, circular coaxial connectors were used for RF (Radio Frequency) connections between substrates. However, in the case of coaxial connectors, after the female and male parts are aligned, they are mechanically fixed using a cylindrical screw. Therefore, if the female and male parts are not positioned accurately, problems such as the signal not being connected or being damaged may occur. In other words, since errors in actual manufacturing tolerance were not allowed, there were difficulties in the manufacturing process, and in the case of cylindrical screws, there were problems such as the lifespan being shortened due to repeated use.

To solve this problem, U.S. Patent No. 8,989,042 proposes a square-shaped RF connector. That is, since an RF connection is implemented by inserting a plug connector (60) into a receptacle connector (80) as shown in FIGS. 7 and 8, it is possible to solve problems that may occur in a method using a conventional coaxial connector. However, in the case of the square-shaped RF connector proposed in U.S. Patent No. 8,989,042, since the four sides of the receptacle connector (80) and the plug connector (60) are in direct contact, there is no free space for shaking during vibration, so there is a disadvantage that it is vulnerable to vibration. In other words, since there is a risk of easy damage when vibration or external impact is applied to the connector, there is a disadvantage that it is difficult to use as a vehicle connector, etc.

The present application seeks to provide a plug connector of a floating B2B connector that is robust against vibration or external shock.

The present application seeks to provide a plug connector of a floating B2B connector that is easy to connect and can secure sufficient floating space.

The present application seeks to provide a plug connector of a floating B2B connector that is easy to connect and can also be blind connected.

A plug connector according to one embodiment of the present invention relates to a floating board to board connector (B2B connector), and includes a plug insulator (110) including a bar-shaped first body portion (111) and a first insertion portion (113) formed at one end of the first body portion (111), wherein when the length of the first body portion (111) is L1, the length of the first insertion portion (113) is L2, and the thickness of the first body portion (111) is D1, and the thickness of the first insertion portion (113) is D2, L1>L2 and D2>D1 may be satisfied.

Here, the plug connector further includes a cover shell that is coupled to cover at least a portion of the plug insulator and includes a second body portion having a shape corresponding to the first body portion and a second insertion portion having a shape corresponding to the first insertion portion, so that the first body portion and the second body portion can be coupled to form a body portion, and the first insertion portion and the second insertion portion can be coupled to form an insertion portion.

Here, the insertion portion may further include support portions protruding on each of the two sides positioned in the width direction of the plug connector.

Here, the support portion may include a first support portion protruding on each of two side surfaces positioned in the width direction of the first insert portion; and a second support portion positioned in the width direction of the second insert portion and formed to cover the first support portion.

Here, the insertion portion may include a guide portion formed on an insertion surface positioned in the insertion direction of the plug connector.

Here, the guide portion may include a plurality of first guide portions formed on the insertion surface of the first insertion portion and formed such that the second insertion portion is fixed on the first insertion portion; and a plurality of second guide portions formed on the insertion surface of the second insertion portion and fastened on the first guide portion to fix the cover shell to the plug insulator.

Here, the first guide part may include a concave position guide part that specifies a position into which the second guide part is inserted; and a fixing protrusion located at both ends of the position guide part to fix the position of the second guide part.

Here, the second guide portion may include a first guide surface extending in the insertion direction from a second insertion portion positioned in the thickness direction; a second guide surface connected to the first guide surface and bent in the direction of the insertion surface; and a third guide surface connected to the second guide surface and bent in the direction of the insertion surface to form a flat surface.

Here, the second support portion may include: a first connecting portion connected to the second insertion portion positioned in the width direction and bent outwardly corresponding to the shape of the first support portion; a first supporting surface connected to the first connecting portion and bent to cover the first support portion to form a flat surface; a second connecting portion extending in the length direction from the first supporting surface and bent inwardly corresponding to the shape of the first support portion; a second supporting surface connected to the second connecting portion and bent to cover the first support portion to form a flat surface; a third connecting portion extending in the width direction from the second supporting surface and bent inwardly corresponding to the shape of the first support portion; and a third supporting surface connected to the third connecting portion and bent to cover the first support portion to form a flat surface.

Here, the plug insulator is formed on an insertion surface positioned in the insertion direction of the plug connector, and may further include a plurality of fixing grooves for fixing the joining positions of the inner shells.

Here, the cover shell may be formed by combining one or two members.

Here, the support member (21) satisfies W3 > (W2-W1) / 2, where W3 may be the length (height) of the support member (21) protruding from the insertion member (20), W1 may be the widthwise length of the body member (10), and W2 may be the widthwise length of the insertion member (20).

Figures 1a and 1b are perspective views showing a plug connector of a floating B2B connector according to one embodiment of the present invention.

Referring to FIGS. 1A and 1B, a plug connector (100) according to one embodiment of the present invention can be divided into a body portion (10) and an insertion portion (20). Here, in FIG. 1A, the configuration of the inner shell and contact portion included in the plug connector is omitted for convenience of explanation.

Hereinafter, a plug connector of a floating B2B connector according to one embodiment of the present invention will be described with reference to FIGS. 1a and 1b and FIGS. 6a and 6b.

A floating board to board connector (B2B connector) according to one embodiment of the present invention includes a plug connector (100) and a receptacle connector (200) connected to different substrates, and may have a structure in which the plug connector (100) and the receptacle connector (200) are combined and electrically connected.
In other words, the plug connector (100) may have a structure in which it is coupled to a coupling groove (201) of a receptacle connector (200) forming a floating board to board connector, and is electrically connected to the contact portion of the receptacle connector through the illustrated contact portion (130).
To this end, the plug connector (100) may include a body part (10) having a contact part (130) mounted therein and having a bar shape having a width, a length, and a thickness as illustrated. In addition, the plug connector (100) may include an insertion part (20) formed to protrude in the longitudinal direction (insertion direction) to be coupled to a receptacle connector from the body part (10).
Meanwhile, the plug connector (100) includes a plug insulator (110) made of an insulating material. As shown in FIGS. 2A and 2B, the plug insulator (110) may include a first body part (111) in the shape of a bar forming the body part (10), and a first insertion part (113) formed to protrude from one end of the length direction of the first body part (111) and forming an insertion part (20).
At this time, the plug connector (100) can be configured to satisfy L1>L2 and D2>D1 when, as in FIG. 3, the length of the first body part (111) is L1, the length of the first insertion part (113) is L2, the thickness of the first body part (111) is D1, and the thickness of the first insertion part (113) is D2.
According to this configuration, when the plug connector (100) is inserted into the insertion groove (201) of the receptacle connector (200) and coupled as shown in FIGS. 6A and 6B, the insertion portion (20) described above is supported by having its outer surface come into contact with the elastic contact projection (210) provided on one side of the inner surface of the insertion groove (201) of the receptacle connector, and the body portion (10) can form a floating section (F) at a gap from the receptacle connector.

In other words, to explain again, the body part (10) constituting the plug connector (100) can be formed in a bar shape, and the insertion part (20) can be formed at one end of the body part (10).

As shown in Fig. 3, the length of the body part (10) may be L1, the thickness may be D1, and the length of the insertion part (120) may be L2, the thickness may be D2. Here, the plug connector (100) according to one embodiment of the present invention may be formed to satisfy L1>L2 and D2>D1.

Meanwhile, the plug connector (100) may further include the plug insulator (110) and the cover shell (140) described above, as illustrated in FIG. 2A. Here, the plug insulator (110) may include a first body portion (111) having a bar shape, a first insertion portion (113) formed at one end of the first body portion (111), and the cover shell (140) may be coupled to cover the plug insulator (110) and may include a second body portion (141) having a shape corresponding to the first body portion (111) and a second insertion portion (143) having a shape corresponding to the first insertion portion (113).

In addition, as shown in FIGS. 4a and 4b, the body part (10) can be formed by combining the first body part (111) and the second body part (141), and the insertion part (20) can be formed by combining the first insertion part (113) and the second insertion part (143).

Here, the insertion portion (20) is formed to be relatively thicker than the body portion (10), so that it can come into contact with the contact projection (210) of the receptacle. In this case, the body portion (10) can float from the receptacle (200) due to the elastic force of the contact projection (210).

Referring to FIGS. 1A and 1B, the insertion portion (20) may further include support portions (21) protruding on each side located in the width direction of the plug connector (100). Here, the support portions (21) may perform a function of maintaining the coupling when the plug connector (100) vibrates in the left-right direction when coupled to the counterpart. In other words, the support portions (21) may support the counterpart and restrict movement within a range of motion when vibrating in the left-right direction. In addition, referring to FIGS. 3(a) and 4B, the height (W3) of the support portions (21) protruding from the insertion portion (20) may be formed to satisfy W3 > (W2-W1)/2. Here, W1 corresponds to the width direction length of the body portion (10), and W2 corresponds to the width direction length of the insertion portion, and through this, coupling with a counterpart such as a receptacle connector may be performed more easily.

Meanwhile, referring to FIG. 2A, the support portion (21) can be distinguished into a first support portion (113A) and a second support portion (143A). That is, the first support portion (113A) may be protruded from each of the two side surfaces located in the width direction of the first insertion portion (113). The second support portion (143A) may be located in the width direction of the second insertion portion (143) and may be formed to cover the first support portion (113A). That is, the second support portion (143A) may protect the first support portion (113A) and guide the support portion (21) to be easily inserted when the plug connector (100) is inserted into a counterpart.

Specifically, referring to FIG. 2b, the second support member (143A) may include a first connecting member (P1), a first supporting surface (P2), a second connecting member (P3), a second supporting surface (P4), a third connecting member (P5), and a third supporting surface (P6).

The first connecting portion (P1) can be connected to the second insertion portion (143) positioned in the width direction, and can be bent outwardly corresponding to the shape of the first support portion (113A). The first supporting surface (P2) is connected to the first connecting portion (P2), and can be bent to cover the first support portion (113A) to form a flat surface. Here, the first supporting portion (113A) can have its outer surface in the width direction covered by the first connecting portion (P1) and the first connecting portion (P2).

Thereafter, the second connecting portion (P3) can be extended in the longitudinal direction from the first supporting surface, and the second connecting portion (P3) can be formed to be bent inwardly corresponding to the shape of the first supporting portion (113A). In addition, the second supporting surface (P4) can be connected to the second connecting portion (P3) and can be bent to cover the first supporting portion (113A) to form a flat surface. That is, the first supporting portion (113A) can be covered in the insertion direction by the second connecting portion (P3) and the second supporting surface (P4).

In addition, the third connecting portion (P5) can extend in the width direction from the second supporting surface (P4) and can be bent inwardly corresponding to the shape of the supporting portion (113A). The third supporting surface (P6) can be bent to cover the first supporting portion (113A) by being connected to the third connecting portion (P5) to form a flat surface. In this case, the third connecting portion (P5) and the third supporting surface (P6) can cover the width direction inner surface of the first supporting portion (113A) and can fix the second supporting portion (143A) to the first supporting portion (113A).

Meanwhile, the insertion portion (20) may further include a guide portion (22). That is, the guide portion (22) may be formed on the insertion surface (A) located in the insertion direction of the plug connector (100), and the guide portion (22) may include a first guide portion (113B) and a second guide portion (143B).

The first guide portion (113B) is formed on the insertion surface (A) of the first insertion portion (113), and a plurality of second insertion portions (143) may be formed so that they are fixed on the first insertion portion (113). Here, the first guide portion (113B) may further include a position guide portion (G1) and a fixing projection (G2). The position guide portion (G1) may be formed in a concave shape to designate a position in which the second guide portion (143B) is inserted, and the fixing projections (G2) may be positioned at both ends of the position guide portion (G1) to fix the position of the second guide portion (143B). That is, the cover shell (113) may be self-aligned by the position guide portion (G1).

The second guide portion (143B) is formed on the insertion surface (A) of the second insertion portion (143), and may be formed in multiple numbers to be fastened on the first guide portion (113B) to fix the cover shell (140) to the plug insulator (110). The second guide portion (143B) may be distinguished into multiple surfaces in order to be fastened within the first guide portion (113B). That is, as illustrated in FIG. 2B, the second guide portion (143B) may include a first guide surface (S1), a second guide surface (S2), and a third guide surface (S3).

The first guide surface (S1) may extend from the second insertion portion (143) located in the thickness direction, and the second guide surface (S2) may be formed to be connected to the first guide surface and bent in the direction of the insertion surface (A). Thereafter, the third guide surface (S3) may be connected to the second guide surface (S2) and bent in the direction of the insertion surface (A) to form a flat surface. That is, a plurality of second guide portions (143B) may be formed to extend from the second insertion portion (143), and each may be bent in the direction of the insertion surface (A) and coupled and fixed to the first guide portion (113B).

Figure 2a is an exploded perspective view showing a plug connector of a floating B2B connector according to one embodiment of the present invention.

Referring to FIG. 2a, a plug connector (100) according to one embodiment of the present invention may include a plug insulator (110), an inner shell (120), a contact portion (130), and a cover shell (140).

Referring to FIG. 2a below, a plug connector of a floating B2B connector according to one embodiment of the present invention is described.

The plug insulator (110) can be implemented with an insulating material that does not conduct electricity, and can include a plurality of fixing grooves (112) for mounting an inner shell (120) and a contact portion (130) therein. That is, the plug insulator (110) can mount each inner shell (120) and contact portion (130) by distinguishing them with the fixing grooves (112), and thereby insulate each inner shell (120) and contact portion (130).

Meanwhile, as illustrated in FIGS. 1A and 1B, when the plug insulator (110) is coupled with a counterpart such as a receptacle connector (not illustrated), the insertion portion (20) that is inserted first may have a relatively thick shape. That is, the plug insulator (110) may be implemented so that its longitudinal cross-section has a T shape, and may be inserted starting from the thick insertion portion (20) when coupled with a receptacle connector, etc. Specifically, the plug insulator (110) may include a first body portion (111), a fixing groove portion (112), and a first insertion portion (113), as illustrated in FIG. 2A.

The first body part (111) can be formed in a bar shape, and the first insertion part (113) can be formed at one end of the first body part (111). The insertion surface (A) is positioned in the insertion direction with respect to the counterpart of the plug connector (100), and can be inserted into the counterpart from the insertion surface (A).

The fixed groove portion (112) can be formed on the insertion surface (A) formed on the first insertion portion (113). A plurality of fixed groove portions (112) can be formed on the insertion surface (A), and as shown in Fig. 2, a plurality of fixed groove portions (112) can be aligned in parallel. Thereafter, an inner shell (120) and a contact portion (130) can be inserted into each fixed groove portion (112).

The inner shell (120) is inserted into each fixed groove (112) and may be implemented with a conductive material. As shown in FIG. 2, the inner shell (120) may have a shape of a hollow square pillar, but depending on the embodiment, it may also be implemented with a polygonal pillar or cylinder. Since the inner shell (120) is implemented with a conductive material, it may perform an electromagnetic shielding function for the contact portion (130) included inside the inner shell (120).

The contact portion (130) is included in the inner shell (120), and when the plug connector (100) is inserted into and coupled with the receptacle connector (not shown), it can form an electrical contact with the receptacle connector. As shown in FIG. 2A, the contact portion (130) can have a shape extending parallel to the length direction of the first body portion (111), and one end can be fixed to the inner shell (120) and the other end can be floated within the inner shell (120). Specifically, as shown in FIG. 2A, the contact portion (130) can include a contact pin (131) and a molding portion (132).

The contact pin (131) may be implemented with a conductive material such as metal, and may form an electrical contact when inserted into the receptacle connector. Here, since the contact pin (131) corresponds to a linear metal pin, it may provide elasticity corresponding to pressure in the up-down or left-right directions. Depending on the embodiment, it is also possible to utilize at least one of the contact pins (131) as a terminal for an RF signal.

The molding part (132) is formed to surround the contact pin (131) to insulate the contact pin (131) and to float the contact pin (131) inside the inner shell (120). Specifically, as shown in FIG. 2A, one end of the molding part (132) is formed to have a size corresponding to the cross-sectional area of the inner shell (120) and can be fixed inside the inner shell (120). Here, one end of the contact pin (131) can be fixed by being coupled to one end of the molding part (132), and the other end of the contact pin (131) extending from one end of the molding part (132) can be floated inside the inner shell (120). That is, the other end of the contact pin (131) can float inside the inner shell (120) without coming into contact with the inner shell (120).

However, the contact pin (131) and the inner shell (120) may be formed of a conductive material, and if the contact pin (131) comes into contact with the inner shell (120) due to external impact, etc., problems such as leakage or short circuit may occur. Therefore, as shown in FIG. 2A, the molding part (132) is formed to surround the contact pin (131), thereby insulating the contact pin (131) from the inner shell (120). Here, since the contact pin (131) needs to form an electrical contact when the plug connector (100) is coupled with the receptacle connector, the molding part (132) may additionally include a contact portion (C) where the contact pin (131) is exposed. That is, the contact portion (130) may form an electrical contact through the contact portion (C) when coupled with the receptacle connector.

The cover shell (140) can be combined to cover the outer surface of the plug insulator (110). In FIG. 2A, an example is shown in which two members of an upper cover and a lower cover are combined to form the cover shell (140), but the cover shell (140) can be formed to combine one or more members. The cover shell (140) can be formed of a material such as metal, and can be combined to the upper surface and the lower surface of the plug insulator (110), respectively, to protect the plug insulator (110) from external impact, etc. In general, the plug insulator (110) can be formed by injection molding using a plastic that is easy to process, but since this has low strength, there is a high risk of damage due to external impact, etc. Therefore, in order to protect the plug insulator (110), the cover shell (140) can be added to cover the outer surface of the plug insulator (110). Here, the cover shell (140) can function as a ground, in which case it can also be connected to the cover shell of the receptacle connector.

Meanwhile, the set length (L2) of the insertion portion (20) may be set in various ways depending on the embodiment, but may be set at least shorter than the depth of the insertion groove of the receptacle connector into which the plug connector (100) is inserted. In addition, depending on the embodiment, the set length (L2) of the insertion portion (20) may be set to be longer than the effective contact length of the contact portion (130). The effective contact length is a length at which the contact portion (130) can form an electrical contact, and corresponds to the length of the contact portion (C). Here, the set length (L2) of the insertion portion (20) may be set to be longer than the effective contact length, so that wiping of the contact portion (C) may be performed.

FIGS. 5A and 5B are schematic diagrams showing the combination of a plug connector (100) and a receptacle connector (200) according to one embodiment of the present invention, and FIGS. 6A and 6B are cross-sectional views at the time of combination. Here, for convenience of explanation, FIGS. 5A and 5B show the configuration of the inner shell (120) and the contact portion (130) included in the plug connector (100) without showing them.

As shown in FIGS. 5A and 5B, the set thickness of the insertion portion (20) can be set to correspond to the size of the insertion groove of the receptacle connector (200). In this case, if the insertion portion (20) of the plug connector (100) is not positioned exactly on the insertion groove of the receptacle connector (200), the connection becomes impossible. That is, when the plug connector (100) is inserted, the insertion position can be easily specified by the insertion portion (20), and through this, the plug connector (100) can be accurately inserted into the insertion groove of the receptacle connector (200).

In general, in the case of a floating B2B connector, a floating gap may be provided within the counterpart to allow the plug connector to be displaced in order to float the connector. However, due to the floating gap, the plug connector may not be precisely aligned with the corresponding counterpart, and in this case, mating of the plug connector may be difficult. In addition, in this case, the worker may repeatedly attempt to mate, and in some cases, there is a risk that the plug connector or the counterpart may be damaged due to a collision.

On the other hand, in the case of the plug connector (100) according to one embodiment of the present invention, since it includes an insertion portion (20), the plug connector (100) can be inserted into the insertion groove of the receptacle connector (200) in close contact with it by the insertion portion (20). Accordingly, the worker can easily insert it into the receptacle connector (200) without having to separately align it with the plug connector (100). That is, even in the case of blind connection where it is difficult to accurately confirm the position of the receptacle connector (200), the worker can easily insert the plug connector (100).

Additionally, as shown in FIGS. 6A and 6B, the plug connector (100) is composed of a body portion (10) and an insertion portion (20), and the insertion portion (20) may be formed to be relatively thicker than the body portion (10). At this time, the receptacle connector (200) may include a bar-shaped body portion, an insertion groove formed on one side of the body portion, and a protrusion formed with a set thickness on the inner surface of the insertion groove.

Here, when the plug connector (100) is inserted into the receptacle connector (200) and connected, the contact projection (210) of the receptacle connector (200) can come into contact with the insertion portion (20) of the plug connector (100), and the plug connector (100) can float due to the elasticity of the contact projection (210). That is, a floating section (F) can be provided between the receptacle connector (200) and the plug connector (100) by the contact projection (210) of the receptacle connector (200), and the contact terminals inserted into the inner shells of each of the receptacle connector (200) and the plug connector (100) can also float.

If a floating section (F) is not provided between the receptacle connector (200) and the plug connector (100), each inner shell is inserted into the fixed receptacle connector (200) and plug connector (100), and thus there is a high risk of damage by hitting the fixed receptacle connector (200) and plug connector (100).

Accordingly, the plug connector (100) according to one embodiment of the present invention can form a floating section (F) when connected to a receptacle connector (200) so that the inner shell can float, and further, by floating the inner shell, the contact portion inside the inner shell can also float. That is, the floating section (F) allows the plug connector (100), the inner shell (120), and the contact portion (130) to float, and also provides a space that can alleviate shock due to external vibration.

The most important point in a floating B2B connector is that even if vibration or external impact is applied after the plug connector (100) and the receptacle connector (200) are connected, the electrical contact between the contact portion (130) of the plug connector (100) and the contact portion of the receptacle is maintained, and the contact portion (130) floats together with the external vibration. Therefore, it is necessary to form a floating section (F) between the plug connector (100) and the receptacle connector (200) so that the inner shell into which the contact portion is inserted can float.

The present invention is not limited to the above-described embodiments and the attached drawings. It will be apparent to those skilled in the art to which the present invention pertains that components according to the present invention can be substituted, modified, and changed within a scope that does not depart from the technical spirit of the present invention.
