Description

socket connector {SOCKET CONNECTOR}

The present invention relates to socket connectors. More specifically, the present invention relates to a socket connector in which the degree of freedom of the connecting portion of the terminal is increased.

In general, when boards are connected to each other, two connectors connected to each board are used by a method such as soldering, and the two connectors may be connected to each other. Here, one of the two connectors is a plug connector, and the other is a socket connector. A socket connector is also called a receptacle connector. These plug connectors and socket connectors may be formed by arranging terminals in a mold unit. A plug connector and a socket connector may be mated to each other to form an electrical connector assembly.

The coupling portion of the socket terminal is easily deformed by repeated engagement and release or continued engagement, which adversely affects the strength of coupling force or durability of the connector.

The technical problem to be solved by the present invention is to reduce the plastic deformation of the coupling part, in particular, the free end of the coupling part.

The technical problems of the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

According to the present invention, a socket connector soldered and mounted on a board includes a base portion, a first wall portion protruding from the upper surface of the base portion, a second wall portion protruding from the top surface of the base portion and intersecting the first wall portion, and an upper surface of the base portion. A third wall portion protruding from and intersecting the second wall portion and facing the first wall portion, and a fourth wall portion protruding from the upper surface of the base portion and intersecting the first and third wall portions and facing the second wall portion. Mold part to do; A bracket installed at least on the first wall portion; and a plurality of socket terminals installed on at least the second wall, wherein at least one socket terminal among the plurality of socket terminals is (a) located outside the socket connector in the width direction and exposed from the sidewall of the mold part. an outer end, the bottom of which is a mounting part mounted on the board, (b) an upper curved part extending convexly toward the top while extending from the outer end to the inside in the width direction of the socket connector, (c) the A lower curved portion that extends from the upper curved portion to the inside of the socket connector in the width direction and is bent convexly downward, and the portion bent convexly toward the lower portion is exposed when viewed from the bottom surface of the mold portion, and (d ) an inner end extending upward from the lower curved portion in the width direction of the socket connector and coupled to a terminal of a mating connector of the socket connector, wherein the at least one socket terminal and the socket mold portion are When viewed from a cross-sectional side view of the socket connector cut in the width direction, (i) a section from the outer end to a predetermined position in the upper curved part is in contact with the socket mold part, and (ii) from a predetermined position in the upper curved part. The socket connector is not in contact with the socket mold part in a section up to the inner end.

Preferably, only a stopper located on at least a part of an upper portion of the lower curved portion covers the socket terminal in a section from a predetermined position of the upper curved portion to the inner end, and the stopper is a part of the socket mold portion; When an inner end of the at least one socket terminal moves upward, the upward movement of the at least one socket terminal is restricted.

Preferably, when the socket connector is viewed from a bottom surface, a mounting portion that is a bottom surface of the outer end portion and a bottom surface of the lower curved portion are exposed.

Preferably, when the socket connector is viewed from a top or bottom surface, a space penetrated vertically exists on a side surface of the inner end portion and an inner side surface of the upper curved portion.

Preferably, when the socket connector is viewed from a top or bottom surface, a space penetrated vertically also exists inside the inner end.

According to embodiments of the technical idea of the present invention, at least the following effects are provided.

The outer end 600-1 of the second socket terminal 600 and the outer side of the upper curved part 600-2 are firmly fixed by the socket mold part 400, and the inner end of the upper curved part 600-2 starts from the inner side of the upper curved part 600-2. Up to (600-4) is a part with a high degree of freedom. It can be seen that the range of movement of the free end from the middle portion of the upper curved portion 600-2 to the inner end portion 600-4 is large. Here, the middle part does not necessarily mean the exact center, and when viewed in the width direction (Y direction) of the socket connector of FIG. 4, any point between the outer and inner sides of the lower surface of the upper curved portion 600-2 (predetermined location). Also in the following description, the middle part does not necessarily mean the exact center, but means a predetermined position in between. That is, the 'predetermined position' may be in the middle of the lower surface of the upper curved portion 600-2, as long as it is between the outer wall and the inner wall, or may be slightly outward from there in the connector width direction (Y direction), or slightly therefrom. It may be biased toward the inside of the connector width direction (Y direction). FIG. 4 shows an example of the predetermined position, and shows an example in which the predetermined position is slightly outward from the center of the side cross-sectional view of the upper curved portion 600-2. Of course, the present invention is not limited to this embodiment, and even if the space S2 is small (that is, in FIG. If the space (S2) exists so that the inner wall part of the lower surface is spaced apart from the mold), the elastic freedom is exhibited.

The overall degree of freedom of the socket terminal 600 is further increased, and plastic deformation is alleviated.

In addition, due to the existence of the surrounding empty spaces S1 and S2, most of the terminals (from the middle of the upper curved portion 600-2 to the inner end 600-4) are free to move, especially the inner end 600-4. 4) The operation is more free. As seen in the empty spaces (S1, S2), it can be moved while freely exerting elastic force upwards and sideways. Due to these spaces, the overall degree of freedom of the socket terminal 600 is further increased, and plastic deformation is alleviated.

In addition, the stopper 400-p is a part of the socket mold part 400 and restricts the upward movement of the socket terminal 600 when the inner end of the socket terminal 600 600-4 moves upward. do. That is, when force is applied in the direction in which the plug terminal of the connector of the socket terminal 600 is coupled and then uncoupled, the socket terminal 600 in the illustration of FIG. 4 is slightly pulled upward and then the coupling is released. . However, if the amount of lifting is too large, there is a risk of deformation/damage of the socket terminal 600 . However, the stopper 400-p prevents such lifting and prevents unnecessary stress and deformation. This also helps improve durability.

The socket connector 20 will be described as follows.

The socket connector 20 may include, for example, a socket mold part 400 , a first socket terminal 500 and a second socket terminal 600 .

The socket mold part 400 (molding part of the socket connector) may have a shape to accommodate a mold part (plug mold part) of a plug connector (not shown). For example, the mold part of the plug connector may have a shape inserted into a space defined by the mold part 400 of the socket connector.

The socket mold unit 400 may be formed of an insulator including resin and epoxy, but is not limited thereto.

The first socket terminal 500 and the second socket terminal 600 may be disposed on a wall portion of the socket mold part 400 . Also, a plurality of first socket terminals 500 and a plurality of second socket terminals 600 may be disposed on the wall portion of the socket mold part 400 .

The socket mold part 400 includes a base portion, a first wall portion 110 protruding from the top surface of the base portion, a second wall portion 120 protruding from the top surface of the base portion and crossing the first wall portion 110, and protruding from the top surface of the base portion. and crosses the second wall portion 120 and faces the first wall portion 110, the third wall portion 130 protrudes from the upper surface of the base portion, intersects the first wall portion 110 and the third wall portion 130, and the second wall portion 130 A fourth wall portion 140 facing the wall portion 120 is included.

For example, the first socket terminal 500 is formed on the first wall portion 110, and a plurality of second socket terminals 600 are formed side by side on the second wall portion 120 adjacent to the first wall portion at an angle of about 90 degrees. , Another first socket terminal 500 is formed on the third wall portion 130 adjacent to the second wall portion 120 at an angle of about 90 degrees, and the fourth wall portion adjacent to the third wall portion 130 at an angle of about 90 degrees ( 140), a plurality of other second socket terminals 600 are formed side by side. Also, the fourth wall portion 140 and the first wall portion 110 are adjacent to each other at an angle of about 90 degrees.

Therefore, the first wall portion 110 and the third wall portion 130 face each other and have a symmetrical shape, and the second wall portion 120 and the fourth wall portion 140 face each other and have a symmetrical shape.

The first socket terminal 500 and the second socket terminal 600 may include a conductive material.

For example, the first socket terminal 500 and the second socket terminal 600 may be formed of a metal material including copper, but are not limited thereto.

Accordingly, when the unshown plug connector is fastened to the socket connector 20, the first plug terminal and the second plug terminal (not shown) are electrically connected to the first socket terminal 500 and the second socket terminal 600. can be connected

For example, a first plug terminal (not shown) may be electrically connected to the first socket terminal 500 and a second plug terminal (not shown) may be electrically connected to the second socket terminal 600 .

For example, when the first plug terminal is a power terminal, the first socket terminal 500 may input/output a power electrical signal. Depending on circumstances, the first socket terminal 500 may simply be referred to as a metal fitting, if only paying attention to the fact that a certain structure exists without paying special attention to the fact that it is a power terminal.

For example, when the second plug terminal is a signal terminal, the second socket terminal 600 may input/output data electrical signals.

The socket connector 20 may be an exemplary socket connector to which a plug connector not shown according to an embodiment is fastened. The socket connector 20 may include, for example, a socket mold part 400 , a first socket terminal 500 and a second socket terminal 600 .

The mold part 400 of the socket connector may have a shape to accommodate a mold part (plug mold part) of a plug connector (not shown). For example, the plug mold part may have a shape inserted into a space defined by the socket mold part 400 .

The socket mold unit 400 may be formed of an insulator including resin and epoxy, but is not limited thereto.

The first socket terminal 500 and the second socket terminal 600 may be disposed on a wall portion of the socket mold part 400 . Also, a plurality of first socket terminals 500 and a plurality of second socket terminals 600 may be disposed on the wall portion of the socket mold part 400 .

In the socket connector 20 of FIG. 1 , each first socket terminal 500 at both ends covers a plastic housing (socket mold part 400). That is, there is no part where the plastic housing covers the first socket terminal 500, and the first socket terminal 500 covers the plastic housing and the first socket terminal 500 is exposed. As a conventional example, there is a case where a part of the first socket terminal 500 (for example, a part corresponding to a corner portion of the socket connector 20) is covered with a plastic housing. Since the metal of the whole is covered, cracking of the housing is prevented and an easier coupling operation is possible.

Meanwhile, as an example, the signal terminal as the second socket terminal 600 may be composed of 32 PINs allowing a current of 0.3A, and the power terminal as the first socket terminal 500 may allow a current of 5A. there is. However, in the example of FIG. 1, the number of PINs is 8. The socket mold part 400 of the socket connector 20 is preferably made of a plastic material, and may be, for example, LCP (Liquid Crystal Polymer). The first socket terminal 500 and the second socket terminal 600 of the socket connector 20 are preferably made of metal, and may be, for example, copper alloy plated with gold (nickel under layer).

FIG. 2 is a top view of the socket connector 20 of FIG. 1 .

In FIG. 2, all eight second socket terminals 600 are shown as having the same shape. Four socket terminals 600 are disposed along the longitudinal direction (X direction) of the connector 20, and two socket terminals 600 face each other along the width direction (Y direction) of the connector 20.

However, this is a preferred embodiment, and the arrangement is not necessarily limited as shown in FIG. 2 . For example, depending on the embodiment, the second socket terminal 600 may be a mixture of a plurality of types (for example, two types).

FIG. 3 is an enlarged view of a part of FIG. 2 .

In FIG. 3 , the second socket terminal 600 (hereinafter also referred to as the socket terminal 600 for convenience) includes an outer end 600-1 (external cutting part), an upper curved part 600-2; It includes a lower curved portion 600-3 (see FIG. 4) and an inner end portion 600-4.

The inner side in the width direction refers to a central position in the width of the socket connector 20. The outside in the width direction refers to both ends in the width of the socket connector 20 . In the example of Fig. 3, both the left and right sides are outside in the width direction, and the middle portion is inside in the width direction.

Since it is difficult to grasp the three-dimensional shape only with the top view of FIG. 3 , the cross-section ab of FIG. 3 will be described below with reference to FIG. 4 which is a side view of the cross-section ab of FIG.

4 is a cross-sectional side view of a cross-section in the direction ab of FIG. 3 seen from the side.

FIG. 4 shows a cross section of the socket terminal 600 cut along a plane (YZ plane) orthogonal to the longitudinal direction (X-axis direction) of the socket connector 20 .

Looking at the schematic configuration, the second socket terminal 600 (socket terminal)

An outer end portion 600, which is a mounting portion 600-m located outside the socket connector 20 in the width direction (Y direction) and exposed at the sidewall of the socket mold portion 400, the bottom of which is mounted on a board. -One),

An upper curved portion 600-2 that is convexly bent upward while extending from the outer end 600-1 to the inside of the socket connector 20 in the width direction (Y direction);

It extends from the upper curved portion 600-2 to the inside of the socket connector 20 in the width direction (Y direction) and is bent convexly toward the bottom, and the portion bent convexly toward the bottom is the socket mold portion 400 The lower curved portion 600-3 exposed when viewed from the bottom of the, and

It extends from the lower curved portion 600-3 to the inside of the socket connector 20 in the width direction (Y direction) and faces upward, and is coupled to the terminal P of the mating connector (plug connector) of the socket connector 20 Inner end (600-4)

includes

When viewed in a cross-sectional side view of the second socket terminal 600 and the socket mold part 400 cut in the width direction (Y direction) of the socket connector 20, (i) the upper curved part 600 from the outer end 600-1 -2) is in contact with the socket mold part 400, and (ii) from the middle part of the upper curved part 600-2 to the inner end part 600-4, the socket mold part 400 is not in contact with

That is, in the socket terminal 600 shown on the left side of FIG. 4, the outer part is firmly fixed by the socket mold part 400, and the inner part (the part from the middle part of the upper curved part to the inner terminal) is the socket mold. It is not fixed by part 400.

As in FIG. 3, also in FIG. 4, the inner side in the width direction refers to a central position in the width of the socket connector 20. The outside in the width direction refers to both ends in the width of the socket connector 20 . In the example of Fig. 4, both the left and right sides are outside in the width direction, and the middle portion is inside in the width direction.

The plug terminal (signal terminal) of the plug connector (not shown) is coupled by being sandwiched between the inner side (inner side in the width direction) of the upper curved portion 600-2 and the outer side (outer side in the width direction) of the inner end portion 600-4. .

The stopper 400-p, which will be described later, may be in contact with the upper surface of the lower curved portion 600-3, or may have a fine gap therebetween.

Also, the bottom surface of the outer end 600-1 of the second socket terminal 600 functions as a mounting portion 600-m mounted on a board.

In the above description, the inner side refers to the middle portion when viewed from FIG. 4 . In Fig. 4, the outer terminal side of the left and right socket terminals is the outer side.

Although it is difficult to clearly define the boundaries of the outer end 600-1, the upper curved part 600-2, the lower curved part 600-3, and the inner end 600-4, as an example, as indicated by the dotted line in FIG. can be grouped together.

As can be seen in FIG. 4 and more clearly through FIGS. 5 and 6 to be described later, when viewed from the bottom, the outer end 600-1 and the lower curved portion 600-3 are exposed.

The lower surface 600-m (mounting part) of the outer end 600-1 of the second socket terminal 600 is equal to or lower than the height of the bottom surface of the socket mold part 400 so that it can be mounted on a board.

The mounting part means that a part of the second socket terminal 600 is bonded to the board by soldering or the like in order to fix the second socket terminal 600 to the board.

As shown in FIG. 4 , the lower portion of the second socket terminal 600 immediately adjacent to the cut portion of the outer end portion 600-1 becomes the mounting portion 600-m.

On the other hand, FIG. 4 shows a cross section of the socket mold part 400, and hatched portions in the cross section indicate a surface that is directly cut when cut in the ab direction. Incidentally, in the socket mold portion 400 in FIG. 4, portions not shaded indicate that they are retracted backward from the cut surface (i.e., they are retracted in the -X direction in FIG. 4). That is, the outer end 600-1 of the second socket terminal 600 and the outer side of the upper curved portion 600-2 are firmly fixed by the socket mold portion 400, and from the inner side of the upper curved portion 600-2. Up to the inner end 600-4 becomes a part with a high degree of freedom.

In FIG. 3, empty spaces S1 and S2 are shown. Referring to the existence of the empty spaces S1 and S2 in FIG. 3, the structure of the same empty spaces S1 and S2 in FIG. 4 can be easily understood. There will be. As described above, the hatched portion of the socket mold part 400 in FIG. 4 is a portion directly cut by the ab-direction cutting plane in FIG. It can be understood that the part marked with is penetrated up and down.

Due to the existence of the empty spaces S1 and S2, most of the terminals (from the middle of the upper curved portion 600-2 to the inner end 600-4) are free to move, especially the inner end 600-4. this is more free

In addition, as shown in the empty spaces S1 and S2 of FIG. 3, it can be moved while freely exerting elastic force upward and sideways.

In FIG. 4 , a stopper 400-p is formed as a part of the socket mold part 400.

That is, in the section from the middle part of the upper curved part 600-2 to the inner end 600-4, only the stopper 400-p located on at least a part of the upper part of the lower curved part 600-3 is connected to the socket terminal 600. is covering Forming the stopper 400-p as a part of the socket mold part 400 in this way is possible by, for example, insert molding.

The stopper 400-p is a part of the socket mold part 400 and restricts the upward movement of the socket terminal 600 when the inner end of the socket terminal 600 600-4 moves upward.

The plug terminal (signal terminal) of the plug connector (not shown) is clamped and coupled between the inner side (inner side in the width direction) of the upper curved portion 600-2 and the outer side (outer side in the width direction) of the inner end portion 600-4. form can be envisaged. However, if the plug terminal of the connector of the socket terminal 600 is coupled and then a force acts in the direction of disengagement, the socket terminal 600 will be slightly pulled upwards and then disengaged. . However, if the amount of lifting is too large, there is a risk of deformation/damage of the socket terminal 600 . However, the stopper 400-p prevents such lifting. This also helps improve durability.

The stopper 400-p may be in contact with the upper surface of the lower curved portion 600-3, or may have a fine gap therebetween.

5 is a bottom view of the socket connector 20 of the present invention viewed from the bottom.

Details thereof will be described later with reference to FIG. 6 .

FIG. 6 is a part of a bottom view of the socket connector 20 of FIG. 5 .

6, the lower curved portion 600-3 of the socket terminal 600 is exposed. In addition, the outer end portion 600-1 serving as the mounting portion 600-m is also exposed.

3, a space S1 exists on the side surface of the inner end portion 600-4 (that is, the side surface in the X direction), and also vertically on the inner side surface of the upper curved portion 600-2. A through space (S2) exists.

In addition, a space S1 penetrating vertically also exists inside the inner end portion 600-4.

Due to these spaces, the overall degree of freedom of the socket terminal 600 is further increased, and plastic deformation is alleviated.

In the above example, it is assumed that all of the plurality of second socket terminals 600 are of the same type, but it is not necessarily limited thereto, and various types of second socket terminals (ie, second socket terminals having different structures) are mixed. There may be.

7 is a side cross-sectional view of the second socket terminal 600 in an operating state.

4 shows a state in which the plug connector is not coupled to the socket connector 20 (that is, a state in which the terminal 600 is not operated), FIG. 7 shows that the plug terminal P is connected to the second socket terminal 600. There is a difference in indicating a coupled state (ie, a state in which the terminal 600 is operated). In FIG. 7, the plug terminal P of the plug socket (not shown) is shown in an arbitrary shape for convenience in order to show the operating state of the second socket terminal 600, and the plug terminal P is shown in FIG. It is not limited to one shape. Rather, the plug terminal (signal terminal) of the plug connector (not shown) is sandwiched between the inner side of the upper curved portion 600-2 (inner side in the width direction) and the outer side (outer side in the width direction) of the inner end portion 600-4. A combined form would be more common.

As shown in FIG. 7 , when the socket connector 20 and the plug connector are coupled, the terminal 600 receives stress and is deformed (moved). As shown in FIG. 7 , it can be seen that the movement range of the free end from the middle portion of the upper curved portion 600-2 to the inner end portion 600-4 is large.

And, when the plug terminal P is disengaged (that is, when the plug terminal P moves upward in the drawing, or when the socket connector 20 moves downward in the drawing), the inner end 600-4 may be dragged upwards somewhat while being in contact with the plug socket (P). However, the stopper 400-p restricts the upper surface of the lower curved portion 600-3 from being pulled up. Therefore, it is possible to solve problems such as the socket terminal 600 being detached due to excessive force during coupling release, while enjoying the advantage of a large movable range of the free end. In addition, it helps to improve the durability of the socket terminal 600.

Referring to FIG. 2 and the like, the case where four terminals are disposed in the X direction has been described, but the number of terminals is not limited thereto and may be any number (8, 16, etc.). In addition, the arrangement of the second wall portion 120 and the fourth wall portion 140 is shown as being regular, and although this is preferable, it is not necessarily limited thereto, and the second socket terminal 600 of different structures is mixed. Embodiments are also possible, and various other modifications are possible.

8 is a side view of the socket connector 20 of FIG. 1 .

It can be seen that the outer end 600-1 of the second socket terminal 600 exists at a position equal to or slightly lower than the bottom surface of the socket connector 20. The bottom surface of this outer end portion 600-1 functions as a mounting portion 600-m, which is a portion mounted on a board by soldering or the like.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above embodiments and can be manufactured in a variety of different forms, and those skilled in the art in the art to which the present invention belongs A person will understand that the present invention may be embodied in other specific forms without changing the technical spirit or essential features.
