Description

Limiting parts of electrical connectors for circuit boards

The present invention relates to a restriction member of an electrical connector for a circuit board.

When this type of connector is connected to the counterpart connector using the direction perpendicular to the surface of the circuit board as the connector fitting direction, the counterpart connector may shift from the normal position in the direction parallel to the surface of the circuit board Therefore, so-called floating connectors that can absorb the above-mentioned displacement are widely used, and are disclosed in Patent Document 1, for example.

The floating connector of Patent Document 1 has a fixed housing (outer housing) that is in the shape of a four-corner frame and is fixed to a circuit board with its bottom surface, and is located in the four-corner frame of the fixed housing and can be relative to the fixed housing. The movable housing (inner housing) that moves has a plurality of terminals arranged so as to straddle the movable housing and the fixed housing. The outer housing is fixed to the circuit board through the terminal by soldering the connection portion of the terminal to the circuit board. The terminal has a wave-shaped elastic part in the middle part of the terminal in the space between the movable housing and the fixed housing, and the elastic displacement of the elastic part is used to absorb the deviation.

The terminal of the connector of Patent Document 1 is formed by integral molding It is held by the fixed housing and the movable housing.

One end of the terminal is embedded in the movable housing, and the contact portion for contact connection with the counterpart connector is fixed to the side surface of the movable housing so as to be exposed. The other end side of the terminal is embedded and held in the fixed housing, and the front end of the terminal protrudes outside the fixed housing to become a connection part soldered to the circuit board.

In Patent Document 1, in this floating connector, when the counterpart connector is pulled out, in order to prevent the friction between the terminals from causing the movable housing (inner housing) to move upward excessively, the fixed housing (outer housing) The body) is equipped with a restricting member (restricting member), which can abut on the upper surface of a part of the movable housing to restrict the upward movement of the movable housing.

The above-mentioned restricting member (restricting member) is formed by bending a metal plate in the direction of its thickness, and has a horizontal lie in which the two sides of the fixed housing are sandwiched from above and below at the ends of the terminal arrangement direction The corner portion of the U-shaped cross-section and the fixing portion for fixing the restricting member to the circuit board are used to form the lower surface of the upper plate and the upper surface of a part of the movable housing among the upper and lower plates of the corner portion Restrictions on contact. With regard to the fixed housing, the restricting member is fitted to the side of the fixed housing by sandwiching the side of the fixed housing between the upper and lower plates of the corner.

[Patent Document 1] JP 2004-063358

However, the restricting member of Patent Document 1 uses the upper plate and the lower plate to form a U-shaped corner that lies horizontally, and the corner is fitted into the corresponding portion of the fixed housing. It is complicated, and the above-mentioned upper plate and lower plate are located on the upper and lower surfaces of the corresponding parts of the fixed housing, which leads to the enlargement of the connector in the vertical direction. In addition, the restriction of the movable member is performed by the upper plate of the above-mentioned corner part. Although the corner part is fitted into the corresponding part of the fixed housing, when focusing on the upper plate, the upper plate is formed only with the upper surface of the corresponding part. In surface contact, if the upper plate is strongly lifted by the movable member from below, the upper plate will tend to float up, which will undeniably lead to a decrease in its strength and thus its limiting ability. Furthermore, in Patent Document 1, although the terminal is held by being integrally molded with the fixed housing and the movable housing, the restricting member is fitted and mounted to the fixed housing. That is, the installation work is performed separately, and the manufacturing workability is poor. In addition, the fitting direction is restricted. Accordingly, the shape of the restricting member is limited. As a result, the enlargement of the restricting member is inevitable.

The present invention has been developed in view of the above-mentioned matters, and its subject is to provide a restraining member for an electrical connector for a circuit board, which can achieve miniaturization and increase the strength and restraint ability.

The limiting member of the electrical connector for the circuit board of the present invention is used to limit the movable amount of the movable housing of the electrical connector for the circuit board. The electrical connector for the circuit board has: fixedly mounted on the surface of the circuit board The fixed housing, the movable housing that is movable relative to the fixed housing, and a plurality of ends arranged in a state of straddling the fixed housing and the movable housing Each terminal has: a fixed-side held portion held by the fixed housing, a movable-side held portion held by the movable housing, and a position between the fixed-side held portion and the movable-side held portion Middle elastic part.

The restriction member is characterized in that, in the present invention, the restriction member is held by the fixed housing by integral molding and has a restriction portion for restricting the movement of the movable housing in the direction away from the circuit board In terms of quantity, the fixed-side held portion is held by the fixed housing by integral molding, and the movable-side held portion is held by the movable housing by integral molding.

By using the restricting element of the present invention in this way, when the restricting portion is used to restrict the movable amount of the movable housing, because the restricting element is held by the fixed housing by integral molding, the restricting portion is formed by the fixed housing It is firmly held to increase the restriction ability of the movable housing. Moreover, because the restricting member is held by the fixed shell, it does not need to be formed into a complicated shape and becomes simplistic. In addition, because the fixed part is located within the wall thickness of the fixed shell, it helps the connector to move up and down. The direction of miniaturization. Furthermore, in the present invention, the terminal is held by the fixed housing and the movable housing by integral molding, and the restricting member can also be held by the integral molding, and the manufacturing steps are simplified.

In the present invention, the form of the restricting member may be configured to have a restricting portion facing 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 this form, since a plurality of fixed legs are provided on the restrictor, the force for holding the restrictor increases, thereby increasing the restricting ability of the movable housing Get bigger. Furthermore, electrical conduction with the circuit board can be achieved through the fixed legs.

The present invention may be configured such that the restricting portion of the restricting member has a flat belt shape extending in the connector width direction perpendicular to the terminal arrangement direction, and a plurality of fixing legs are provided at both ends of the restricting portion in the connector width direction Location and the location of the middle. In this way, because the middle part of the flat belt-shaped restricting part is also equipped with a fixed leg part, it is not necessary to increase the height direction dimension of the connector to increase the force used to hold the restrictor, and even if the restricting part is freely movable The strength of the shell is still not easy to flex and increase the strength.

In the present invention, as described above, in an electrical connector for a floatable circuit board, a part of the restricting member for restricting the upward momentum of the movable housing is held by integral molding with the fixed housing. The above-mentioned restricting member can be integrally formed and held while the terminal is integrally formed and held. Therefore, the workability during manufacturing is improved. In addition, the held part for the integral forming and holding of the restricting member is located within the wall thickness of the fixed housing, because it is not It is located outside the fixed housing, and can be miniaturized in the vertical direction corresponding to this. In addition, because the above-mentioned held part is buried in the wall thickness of the fixed housing, even if the restricting part receives a large force from the upper side of the movable housing, it will not float up from the fixed housing and be held firmly, thereby making it The ability to restrict the movable housing is improved. Furthermore, since the restricting member is not fitted into the fixed housing as in the past, it does not cause an increase in size or restriction of the mounting direction, and can achieve the miniaturization of the restrictor in this direction.

Next, returning to the socket connector 1, the socket connector 1 will be described in more detail according to FIGS. 2 to 5.

As shown in FIG. 2, on 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 are used to form the receiving space 1A. The terminal groove 13 and the terminal groove 22 facing each other are aligned and formed. In addition, in the movable housing 21, the lower end of the groove wall 23 formed between the terminal grooves 22 of the movable housing 21 extends toward the fixed housing 11 to form a rib 23A. All the ribs 23A located at the lower ends of the plurality of groove walls 23 are located at the bottom of the receiving space 1A of the socket connector 1, thereby forming a bottom holding portion 24 extending along the longitudinal direction of the movable housing 21. The arrangement direction of the terminal groove 22 of the movable housing 21 is two The end is provided with a plate-shaped restricted portion 25 having a step that protrudes from the lower part of the movable housing 21 in the arrangement direction of the terminal groove 22 (see FIG. 3).

On the other hand, in the present embodiment, the terminal 30 of the receptacle connector 1 is a form of a so-called bent terminal by bending a metal strip in the thickness direction. In the present invention, the terminal is not limited to a bent terminal, and may be 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, as shown in FIGS. 2, 4, and 5(A), has a substantially waveform having two inverted U-shaped portions as a whole, and is located in an inverted U-shape on one of the side walls 12 of the fixed housing 11 The part constitutes the 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 located on the other side of the movable housing 21 forms a contact arm portion 32 having two arm portions 32A and 32B. The two arm portions 32A, 32B, except for the base portion of the arm portions 32A, 32B, are mostly accommodated in the terminal groove 22 of the movable housing 21. The upper part of the above-mentioned arm portions 32A, 32B is contacted by 33 connected. The contact portion 33 is convexly curved and formed so as to protrude out of the terminal groove 22.

The above-mentioned intermediate elastic portion 31 of the terminal 30 extends obliquely from the lower end of the arm portion located on the inner side of the terminal groove 13 to become the fixed side held portion 34, and the fixed side held portion 34 is buried by integral molding It is held in the lower part of the side wall 12 of the fixed housing 11, and from the fixed side held portion 34, one end of the terminal 30 extends to the outside of the side wall 12 and along the lower surface of the side wall 12, and the end side is formed for The connection part 35 for soldering with the circuit board.

Among the two arms 32A, 32B of the above-mentioned contact arm 32, the structure The base portion 32A-1, which is the lower end portion of the arm portion 32A located on the inner side of the terminal groove 22, is bent into an L-shape, and is buried and held in the lower portion of the movable housing 21 by integral molding. On the other hand, the base portion 32B-1 constituting the lower end portion of the arm portion 32B located on the opening side of the terminal groove 22 is bent in an L-shape and penetrates the bottom holding portion 24 of the movable housing, and is two of the middle elastic portion 31 Among the arms, the lower ends of the arms located on the opening side of the terminal groove 13 are connected. The base portion 32B-1 of the arm portion 32B becomes the movable side held portion 36 and is held by integrally molding with the bottom holding portion 24.

As described above, the two arm portions 32A, 32B of the contact arm portion 32 that are connected by the contact portion 33 and have an inverted U-shape of the terminal 30, the base portions 32A-1, 32B-1 of which are connected to the movable shell The body 21 is integrally molded and held, and the inverted U-shaped portion above the base portions 32A-1, 32B-1 is not restrained in any way and becomes elastically displaceable. Of course, the middle elastic portion 31 is not restrained and can be elastically displaced.

The restrictor 40 made of a metal plate held by the fixed housing 11, as shown in FIG. 3 showing the movable housing 21, the terminal 30, and the restrictor 40 while omitting the fixed housing 11, has: facing the movable housing 21. The upper surface of the restricted portion 25 is a flat belt-shaped restriction portion 41 extending in the connector width direction, and a fixed leg portion 42 extending from the restriction portion 41. The fixing legs 42 are provided on both ends and sides of the restriction portion 41. Each fixing leg 42 is bent downward in a crank shape, and the lower end is welded and fixed to the corresponding portion of the circuit board.

Such a restriction member 40 is provided with the fixed leg portion 42 in the restriction portion 41 facing the restricted portion 25 of the movable housing 21 The edge portion and the base portion of the fixed leg portion 42 are buried in the fixed housing 11 by integral molding, and are held by being integrally molded with the fixed housing 11. In other words, the part buried and held by the fixed housing 11 is exposed.

Since a part of the restricting member 40 is held by the fixed housing 11 by integral molding, compared with the holding by press-fitting, it is not necessary to consider the part required for press-fitting of the restricting member, so space saving can be achieved. The shape of the restrictor can be simplified, and the press-in direction is not restricted, and the shape of the restrictor can be simplified, which also contributes to space saving.

The socket connector 1 of this form is used according to the following methods. First, in the receptacle 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 restricting member 40 is soldered and fixed to the corresponding portion of the circuit board.

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 the corresponding circuit portion of another circuit board (not shown).

Then, as shown in FIGS. 1 and 5, the plug connector 2 mounted on the above-mentioned other circuit board is placed in a posture where the above-mentioned other circuit board is located upward, that is, the posture where the recess 51A of the plug connector 2 opens downward. , Is arranged directly above the receptacle connector 1 mounted on the above-mentioned circuit board, and is lowered as it is.

When the plug connector 2 is lowered, the movable housing 21 of the socket connector 1 enters the recess 51A of the plug connector 2 together with the contact arm 32 of the terminal 30, and the plug connector is received in the receiving space 1A of the socket connector 1. Connector 2 (refer to Figure 5(B)).

As shown in FIG. 5(B), when the mating of the plug connector 2 progresses to the predetermined depth of its lower end abutting the bottom holding portion 24 of the socket connector 1, the two rows of the plug connector 2 The terminal 60 is in contact with the contact portion 33 of the terminal 30 in the two rows of the socket connector 1 from the inside in the connector width direction. The contact portion 33 is located on the upper part of the contact arm portion 32 formed by the two elastic arms 32A, 32B, and is connected to the plug by the elastic force caused by the elastic deflection displacement of the two arms 32A, 32B The contact portion 62 of the terminal 60 of the device makes contact.

Here, for example, when the plug connector 2 is fitted to the receptacle connector 1 in a position shifted from a predetermined position in the left-right direction to the receptacle connector 1, corresponding to the shift amount, the above-mentioned receptacle connector 1 is made up The middle elastic part 31 of one of the two terminals 30 of the pair is elastically displaced in such a way that the two legs of the inverted U shape are opened, and the middle elastic part of the other terminal is closed by the two legs of the inverted U shape. In this way, the movement of the plug connector 2 becomes possible, which is called floating.

The above floating state can be clearly understood from Figure 6(A) and (B). Figure 6 (A), (B) is a view of the connector 1 viewed from above, Figure 6 (A) shows the case where the movable housing 21 is in the normal position with respect to the fixed housing 11, and Figure 6 (B) shows the movable housing 21 For the case where the fixed housing 11 is in a floating position. In FIG. 6(A), the movable housing 21 is in a symmetrical normal position with respect to the fixed housing 11 without shifting in the up-down and left-hand directions. In this normal position, as shown in the upper and lower parts of FIG. 6(A), the gap δ between the movable housing 21 and the fixed housing 11 is formed equally, and the movable housing The restricted portion 25 on the left and right sides of 21 is restricted by the restricting portion 41 of the restricting member 40 with the same area. In this regard, when viewed from above, it is clearly understood that the restricted portion 25 that is not in contact with the restricting portion 41 is shown with 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. Furthermore, in the left-right direction, the restricted portion 25 on the right is restricted by the restricted portion 41 in a state where the restricted portion 25 on the right is in contact with 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 in the state of FIG. 6(A). This floating is made possible by the elastic displacement of the elastic part 31 of the terminal 30 as shown in FIG. 6(B).

Regardless of whether the plug connector 2 is fitted in the normal position or in the offset position, the terminal 30 of the above-mentioned socket connector 1 can have the contact arm 32 of the terminal 30 in either of the two arms. The bases of the parts 32A, 32B are firmly held by being integrally formed with the movable housing 21, and because they extend sufficiently long upward from the base, the elasticity between them and the terminal 60 of the plug connector 2 The contact pressure generated by the displacement is ensured to be sufficiently large.

In this way, the terminal 30 of the socket connector 1 uses its contact portion 33 to contact the terminal 60 of the plug connector 2 with a relatively large contact pressure. Therefore, when the plug connector 2 is pulled out, the socket connector 1 is in contact with The portion 33 has a relatively large frictional force acting in the pull-out direction, and the movable housing 21 tends to move upward due to the force to increase the movable amount.

In this embodiment, the restrictor 40 is held by the fixed housing 11 and is arranged so that the restricting portion 41 of the restrictor 40 faces the upper surface of the restricted portion 25 of the movable housing 21. Therefore, when the plug connector 2 is pulled out, 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 will abut against the restricting portion 41 and move upward. Movement is restricted. The restricting portion 41 is always in contact with the upper surface of the restricted portion 25 before being pulled out from the plug connector 2.

The above-mentioned restricting member 40 is integrally formed to be firmly held by the fixed housing 11. The restricting member 40 itself is also fixed to the circuit board by means of its plurality of fixing legs 42 by welding, so even if the restricting portion 41 is received The upward force from the movable housing 21 can still restrict the upward momentum of the movable housing 21 with sufficient strength.

Next, the essentials of integral molding of the restricting member 40 and the fixed housing 11 of this embodiment will be described based on FIG. 7. FIG. 7 is a partial cross-sectional view of the restricting member 40 and the upper mold M1 and the lower mold M2 for molding. It is the restricting member 40 of FIG. 4 at two fixed arms extending from the side edge of the restricting portion 41 In the position between the portions 42, the restricting portion 41 is cut with a surface extending in the terminal arrangement direction.

In FIG. 7(A), the upper mold M1 is formed with a space M1-A for molding the end wall of the fixed housing 11, a space M1-B for molding the movable housing 21, and a space M1-B formed in The segmental portion M1-C of the restricting portion 41 of the restricting member 40 is located on the lower surface of the wall between the space M1-A and the space M1-B. On the other hand, the lower mold M2 has a shallow recessed space for forming the bottom of the end wall of the fixed shell M2-A, a space M2-B for forming the bottom of the movable housing 21 including the restricted portion 25, and a protrusion M2-C; the protrusion M2-C is used to be part of the lower portion of the restriction 41 The surfaces abut, so that the space M1-A and the space M2-A become one closed room, and the space M1-B and the space M2-B become another closed room.

Between such an upper mold M1 and a lower mold M2, first, the restrictor 40 is arranged as shown in FIG. 7(A), and then as shown in FIG. 7(B), the restricting part 41 of the restrictor 40 The protrusion M2-C of the lower mold abuts the lower surface of the restricting portion 41 in a state of being arranged in the space M1-C of the upper mold M1. In this state, the upper mold M1 and the lower mold M2 form a closed forming space that can be molded. The space M1-A of the upper mold M1 and the space M2-A of the lower mold M2 form a closed chamber for For the formation of the end wall of the fixed housing 11, the space M1-B of the upper mold M1 and the space M2-B of the lower mold M2 form another closed chamber for forming the movable housing 21. In this state, as shown in FIG. 7(C), molten resin is injected into the above-mentioned molding space for molding. After the resin is cured, the upper mold M1 and the lower mold M2 are separated and removed, as shown in FIG. 7(D) A one-piece molded product of the fixed housing 11, the movable housing 21 and the restricting member 40 is obtained.

In the state of FIG. 7(D), the restricting member 40 is buried in the fixed housing 11 between the restricting portion 41 and the fixed portion 42, so the restricting member 40 is firmly held by the fixed housing 11. On the other hand, the movable housing 21 only makes surface contact with the lower surface of the restricting portion 41, and can be easily peeled off from the restricting portion 41 by applying a slight external force. In this way, the movable housing 21 becomes a movable state with respect to the restriction member 40.
