Description

Electrical connector for circuit board

The present invention relates to electrical connectors for circuit boards.

In this type of connector, when the connector is connected to the opposing connector with the direction at right angles to the surface of the circuit board as the connector fitting direction, it is inserted at a position shifted from the normal position in a direction parallel to the surface of the circuit board. Since the opposing connectors are connected together, so-called floating connectors that can absorb the above-mentioned deviation can be widely used, for example, as disclosed in Patent Document 1.

The floating connector of Patent Document 1 has: a fixed housing (shell body) formed in a quadrangular frame shape and fixed to the circuit board on its bottom surface; and movable relative to the fixed housing in the four-corner frame of the fixed housing Housing (housing connection part); and plural terminals (contacts) arranged in a state straddling the movable housing and the fixed housing. In the above-mentioned fixed case, the connection part of the terminal is soldered to the circuit board, and the terminal is fixed to the circuit board through the terminal. The terminal has a substantially L-shaped elastic part in the middle part of the terminal in the space between the movable housing and the fixed housing, and the above-mentioned deviation is absorbed by the elastic displacement of the elastic part.

The terminal of the connector of Patent Document 1 is formed by bending a metal strip in the plate thickness direction, that is, the so-called bent terminal (Patent Document 1, paragraph [0041]) According to Patent Document 1, the terminal can be assembled or integrally formed with respect to the fixed housing and the movable housing described above (paragraph [0053]).

The terminal has one end buried in the movable housing, and the contact portion for contacting and connection with the counter connector is fixed to the side surface of the movable housing so as to be exposed. In addition, the above-mentioned terminal is buried in the fixed case and held the other end side, and the front end thereof protrudes to the outside of the fixed case, and becomes a connection part for soldering and connection to the circuit board (see Fig. 5).

The elastic part of the above-mentioned terminal is formed in a substantially L-shaped groove between the movable housing and the fixed housing facing the receiving space of the receiving opposite connector, and can be elastically displaced in the groove. The connector with the above-mentioned receiving space is generally called a socket connector, and the opposite connector is called a plug connector.

[Patent Document 1] Japanese Patent No. 4411843

However, in the connector of Patent Document 1, the contact part of the terminal for contact connection with the counter connector is fixedly mounted on the side surface of the movable housing. Therefore, the terminal of the counter connector must have an elastically displaceable contact part. The plug connector that is fitted and connected to the socket connector of Patent Document 1 as the opposite connector is different from the socket connector. The contact part of the terminal is preferably a fixed contact part that is firmly fixed on the outer side of the plug housing , The form of elastic displacement is not respected.

Therefore, when the receptacle connector of Patent Document 1 is a plug connector in the form of a fixed contact portion fixed to the outer surface of the plug housing relative to the connector, the contact portion of the terminal on the receptacle connector side is formed to be fixed relative to the movable housing The fixed contact part of the installation cannot be elastically displaced, so it cannot correspond to the socket connector of the fixed contact part.

In Patent Document 1, the terminal has an elastic portion and can float. The floating terminal needs to be thin and thin in order to ensure the elastic displacement of the elastic part for floating. However, once a sufficient amount of elastic displacement is ensured, the terminal including the elastic contact portion will also become thinner and thinner. As a result, the elastic contact portion will become too soft to obtain a sufficient contact pressure.

In addition, according to Patent Document 1, although there is a description that the terminal can be held by a movable housing and a fixed housing even if it is integrally formed, in this type of connector, although the terminal is bent in the plate thickness direction, it is a bent terminal. However, if it is a terminal that can be removed in the thickness direction, the width of the terminal is reduced due to the purpose of arranging the terminals in a high-density pitch. Although it can be integrally molded and held, when the contact part of the terminal is elastically displaced However, due to the small width of the terminal, it is difficult to obtain sufficient compressive strength relative to the contact pressure with the counterpart connector.

In view of the above-related problems, the present invention provides a connector that can ensure sufficient contact pressure at the contact portion of the terminal even if it is a floating connector, and even if the terminal is arranged in a high density, the small terminal and the housing with a wide terminal are provided. In the case of integral molding, it is still possible to have a contact part that can be elastically displaced on a small terminal with this terminal width, even for non-elastically displaced solid The problem is that the relative connector of the terminal of the fixed contact part can still be used in the circuit board.

The electrical connector for a circuit board of the present invention has: a fixed housing fixedly mounted on the surface of the circuit board; a movable housing movable relative to the fixed housing; and plural terminals arranged across the fixed housing and the movable housing , And has: a fixed side held part held by a fixed housing; a movable side held part held by a movable housing; and an intermediate elastic part located between the fixed side held part and the movable side held part .

In the related electrical connector for a circuit board, the present invention is characterized in that the terminal has: a connecting portion extending from the fixed side held portion at one end outside the fixed housing and connected to the circuit board, and The fixed-side held part is further located at the other end side of the terminal. The contact wrist is movably housed in the groove formed in the movable housing. The contact wrist has two elastic wrists connected by the contact part. The movable side held portion is formed on the respective bases of the two arm portions, the fixed side held portion is held by the fixed housing, and the movable side held portion is held by the movable housing.

In the related configuration of the present invention, the base of the wrist is integrally formed with the movable housing to hold the contact wrist with two wrists, and the two wrists connected by the contact are elastic in parts other than the above-mentioned base. It is deformed, so it can ensure the long elastic part of the wrist on one side, and form a large contact pressure of the contact part. The contact wrist is held by the bases on both sides, so the strength of the contact wrist is increased.

In the present invention, the fixed housing is equipped with a restricting metal piece that restricts the amount of movement of the movable housing in the direction separating from the circuit board. In this way, the metal member is restricted from moving in the pull-out direction of the movable housing when the connector is pulled out to protect the terminal.

In the present invention, the restricting metal piece has a restricting portion opposed to the upper surface of a part of the movable housing, and a plurality of fixed legs extending from the restricting portion and fixedly connected to the circuit board. In the above-mentioned form, a plurality of fixed feet are provided on the restricting metal piece, so the force for holding the restricting metal piece becomes larger, so that the restricting ability of the movable housing increases. In addition, electrical continuity with the circuit board can also be achieved by fixing the legs.

In the present invention, the restricting portion of the restricting metal piece is formed in a flat belt shape extending in the connector width direction perpendicular to the terminal arrangement direction, and a plurality of fixing legs can be provided at both ends of the restricting portion in the connector width direction The position of the part and the position of the middle part. In this way, the middle portion of the flat-belt-shaped restricting portion is also provided with a fixing foot portion, so the height direction dimension of the connector will not increase, and the restricting ability of holding the restricting metal can still be increased.

As explained above, in the present invention, a contact arm having two elastic arm parts connected by a contact part is provided in the terminal, and the bases of the two arm parts are integrally formed with the movable housing and held by the movable housing Therefore, even the two wrists of the floating connector still have a large elastic displacement to ensure sufficient elastic displacement at the contact part, so the strength of the contact pressure relative to the contact part is improved, and the two wrists Movable shell Holding can also improve the holding strength of the contact wrist.

The middle part of the above-mentioned terminal 60 is bent into an L-shape, and has a vertical part held by one side of the side wall 52 and exposed from the side wall 52 and a horizontal part bent from the vertical part. The vertical part forms the contact part 63. The moving portion toward the horizontal portion is buried in the plug housing 51 to form a held portion 64 held by the plug housing 51.

Next, based on the receptacle connector 1 and Figures 2 to 5 as the basis, the receptacle connector 1 will be described in further detail.

As shown in Figure 2, of the fixed housing 11 and the movable housing 21 of the socket connector 1, the inner surface of the side wall 12 of the fixed housing 11 and the side wall of the movable housing 21 forming the receiving space 1A are arranged so that the terminals The groove 13 and the terminal groove 22 are formed opposite each other. In addition, the movable housing 21 is such that the lower ends of the groove walls 23 formed between the terminal grooves 22 of the movable housing 21 extend toward the fixed housing 11 to form a rib 23A. All the ribs 23A located at the lower end of the plurality of groove walls 23 are located at the bottom of the receiving space 1A of the socket connector 1 and form a bottom holding portion 24 extending in the longitudinal direction of the movable housing 21. The above-mentioned movable housing 21 is arranged at both ends of the terminal groove 22 in the arrangement direction, provided from the movable housing The lower portion of the body 21 is a stepped plate-shaped restricted portion 25 protruding in the arrangement direction of the terminal grooves 22.

On the other hand, in the present embodiment, the terminal 30 of the receptacle connector 1 is formed by bending a metal strip in the thickness direction thereof, that is, forming a so-called bent terminal. In the present invention, the terminal includes not only a bent terminal, but also a form in which a metal plate is punched in the thickness direction, that is, a so-called stamped terminal.

The above-mentioned terminal 30 is as shown in FIG. 2, FIG. 4, and FIG. 5(A), and is formed as a whole with two inverted U-shaped waveforms, which are located on one of the side walls 12 of the fixed housing 11 The shape part forms an intermediate elastic part 31 and is accommodated in the terminal groove 13 formed in the side wall 12. In addition, the inverted U-shaped portion on the other side of the movable housing 21 forms a contact arm portion 32 having two arm portions 32A and 32B. The two wrists 32A, 32B are except for the bases of the wrists 32A, 32B. Almost these parts are contained in the terminal groove 22 of the movable housing 21. The aforementioned wrists 32A, 32B are in these The upper part is connected by a contact part 33. The contact portion 33 is bent and formed to protrude out of the terminal groove 22.

The above-mentioned intermediate elastic portion 31 of the terminal 30 is formed as a fixed-side held portion 34 extending obliquely from the lower end of the arm portion located on the deep side of the terminal groove 13, and the fixed-side held portion 34 is formed on the side wall of the fixed housing 11. The lower part of the 12 is buried and held by integral molding, and one end of the terminal 30 is extended from the fixed-side held portion 34 to be located outside the side wall 12 and positioned along the underside of the side wall 12 to form a soft end side. Solder connection to the connection part 35 for the circuit board.

The above-mentioned contact wrist 32 is a combination of its two wrists 32A, 32B Among them, the base portion 32A-1, which is located on the deep side of the terminal groove 22 and becomes the lower end of the arm portion 32A, is bent into an L-shape, and is buried and held in the lower part of the movable housing 21 by integral molding. On the other hand, the base 32B-1 of the lower end of the arm 32B located on the opening side of the terminal groove 22 is bent into an L shape and penetrates the bottom holding part 24 of the movable housing and the middle elastic part 31 The lower end of the arm located on the opening side of the terminal groove 13 among the two arm parts is connected. The base portion 32B-1 of the arm portion 32B is the movable side held portion 36 and is held by being integrally formed with the bottom portion holding portion 24.

The terminal 30 is as described above, and the two arms 32A, 32B of the contact arm 32 in the reverse U-shape are connected by the contact portion 33. The movable housing 21 is integrally formed to hold the bases 32A-1, 32B. -1, the inverted U-shaped part above the base 32A-1, 32B-1 is not subject to any restriction and can be elastically displaced. Of course, the middle elastic portion 31 is not subject to any restriction, and thus can be elastically displaced.

The metal plate-made restricting metal piece 40 held by the fixed housing 11 is shown in Figure 3 where the fixed housing 11 is omitted, the movable housing 21, the terminal 30, and the restricting metal piece 40 are shown. The upper surface of the restricted portion 25 described above is opposed to a flat belt-shaped restricting portion 41 extending in the connector width direction, and a fixed leg portion 42 extending from the restricting portion 41. Although the fixing legs 42 are provided on both ends and sides of the above-mentioned restricting portion 41, they are all bent downward into a crank shape, and the lower ends are soldered and fixed to the corresponding portions of the circuit board.

The aforementioned restricting metal piece 40 is formed by integrally forming the aforementioned fixed leg portion of the restricting portion 41 opposite to the restricted portion 25 of the movable housing 21 The edge of the positioning 42 and the base of the fixed leg 42 are buried in the fixed housing 11 and held by the integral molding of the fixed housing 11. In other words, the parts buried and held by the fixed casing 11 are exposed.

The above-mentioned restricting metal piece 40 is a part of which is integrally formed and held in the movable housing 21. Compared with the holding by press-fitting, it is not necessary to consider the press-in margin of the restricting metal piece to achieve space saving, and does not restrict the pressure. The inward direction can simplify the shape of the restricting metal piece, which can further improve the space saving.

The socket connector 1 of the above-mentioned form is used as follows. First, in the socket connector 1, the connecting portion 35 of the terminal 30 is soldered to the corresponding circuit portion of the circuit board (not shown), and the fixing leg portion 42 of the restraining metal member 40 is soldered to the circuit board. The counterpart.

On the other hand, the plug connector 2 is also the same as the receptacle connector 1, and the contact portion 62 of the terminal 60 of the plug connector 2 is soldered to a corresponding circuit portion of another circuit board (not shown).

After that, the plug connector 2 mounted on the above-mentioned other circuit board, as shown in Figures 1 and 5, with the above-mentioned other circuit board as the upper posture, that is, with the recess 51A of the plug connector 2 opening downward. The posture becomes the position directly above the socket connector 1 mounted on the above-mentioned circuit board, and it descends in its state.

When the plug connector 2 is lowered, the movable housing 21 of the socket connector 1 and the contact wrist 32 of the terminal 30 enter the recess 51A of the plug connector 2 together, and the plug connector 2 is received in the receiving space of the socket connector 1 1A (see Figure 5(B)).

As shown in Figure 5(B), connect the plug connector 2 to its lower end When fitted to the predetermined depth of the bottom holding portion 24 of the socket connector 1, the terminals 60 provided in the two rows of the plug connector 2 are the contact portions 33 and the connector of the two rows of the terminals 30 of the socket connector 1 The width direction abuts from the inside. The contact portion 33 is located on the upper part of the contact arm portion 32 composed of two elastic arms 32A, 32B, so that the elastic thrust of the elastic bending displacement of the two arms 32A, 32B interacts with the plug connector The contact portion 62 of the terminal 60 is in contact.

Here, for example, when the plug connector 2 is fitted into the receptacle connector 1 at a position shifted from a predetermined position in the left-right direction with respect to the receptacle connector 1, the receptacle connector 1 is paired by the offset amount The middle elastic part 31 of one terminal of the two terminals 30 elastically displaces to form its inverse U-shaped two-leg opening, and the middle elastic part of the other terminal is elastically displaced to form its inverse U-shaped two-leg With the feet closed, the plug connector 2 can be moved, that is, so-called floating.

The state of the above floating can be clearly understood in Figure 6(A) and (B). Figures 6(A) and (B) are diagrams showing the connector 1 from above, Figure 6(A) shows the case where the movable housing 21 is in the normal position relative to the fixed housing 11, and Figure 6(B) It shows that the movable housing 21 is in a floating position relative to the fixed housing 11. In FIG. 6(A), the movable housing 21 is a regular position that is symmetrical to the fixed housing 11 in any one of the vertical and horizontal directions. In this normal position, the movable housing 21 is shown in the upper and lower parts of Figure 6(A), and an equal gap δ is formed between the movable housing 21 and the fixed housing 11. The left and right restricted portions 25 of the movable housing 21 are The restriction portion 41 of the restriction metal member 40 is restricted by the same area. This is shown from above, but never It can be clearly seen that the restricted portion 25 that the restricting portion 41 abuts has the same area on the left and right.

On the other hand, in FIG. 6(B) in the floating state, the movable housing 21 moves diagonally to the upper right with respect to the fixed housing 11. That is, the upper gap δ in Fig. 6(A) disappears, and the lower gap increases. In addition, in the left-right direction, the restricted portion 25 on the right is restricted by the restricted portion 41 in a state of abutting against the restricted portion 41 with a larger area than the restricted portion 25 on the left. In other words, the unrestricted area of the restricted portion 25 on the left is smaller than that in Fig. 6(A). This floating is as shown in FIG. 6(B), and the terminal 30 can be elastically deformed by the elastic portion 31.

Even if the terminal 30 of the socket connector 1 is fitted in a normal position or fitted with an offset, the contact arm 32 of the terminal 30 is at the base of the two arm parts 32A and 32B. One side is integrally formed with the movable housing 21 and held firmly, and extends from the base to a sufficient length, so that the contact pressure with elastic displacement with the terminal 60 of the plug connector 2 can be sufficiently ensured.

As mentioned above, the terminal 30 of the receptacle connector 1 is in contact with the terminal 60 of the plug connector 2 at its contact portion 33 with a large contact pressure. Therefore, when the plug connector 2 is pulled out, it is shown that the receptacle connector 1 is in the contact portion. 33 has a large frictional force acting in the pull-out direction, and the movable housing 21 has a tendency to move upward by its force to increase the amount of activity.

In this embodiment, a restricting metal piece 40 is held in the fixed housing 11, and the restricting portion 41 of the restricting metal piece 40 is located opposite to the upper surface of the restricted portion 25 of the movable housing 21. Therefore, the plug connector 2 is unplugged At this time, even if the movable housing 21 is pulled upward by the frictional force of the contact portion 33 of the terminal 30, the restricted portion 25 is abutted against the restricting portion 41 to restrict upward movement. The restriction portion 41 may be in contact with the upper surface of the restricted portion 25 from the beginning before the plug connector 2 is pulled out, or there may be a gap between the upper surfaces of the restricted portion 25 at the beginning.

Although the above-mentioned restricting metal piece 40 is firmly held by integrally forming the fixed housing 11, the restricting metal piece 40 itself can be soldered and fixed to the circuit board with its plural fixing legs 42. Therefore, even if the restricting portion 41 is affected by movement The upward force of the housing 21 can still be strong enough to limit the upward movement of the movable housing 21.

The present invention is not limited to the examples shown in FIGS. 1 to 6 and can be modified in various ways.

For example, although the terminal 30 of the existing receptacle connector 1 is a pair of opposing terminals 30 as separate members, it may be formed as a member connected to each other. In the case of Fig. 6(A), with respect to the movable housing 21, the terminal 30 with the contact portion 33 on the left and right is a member, so that one arm 32A is formed downward from the contact portion 33 and the other arm 32B is formed The contact wrist 32 extends in the lateral direction. The base of one arm 32A is held by the bottom holding part 24 of the movable housing 21 as in the conventional form, and the base of the other arm 32B is held by the upper part of the central wall of the movable housing 21.

The terminal 30 in FIG. 7(A) may be separated into two terminals 30 in a pair. For example, in FIG. 7(B), the base of the other arm is held by the upper part of the center mold of the T-shaped cross-sectional shape of the movable housing 21.
