Description

  The present invention relates to an electrical connector configured to hold a signal transmission medium inserted into a connector main body by a lock engaging portion.

  2. Description of the Related Art Conventionally, an electrical connector for electrically connecting a signal transmission medium such as a flexible flat cable (FFC) or a flexible printed circuit board (FPC) to a circuit wiring board has been widely used in various electric devices. The electrical connector is mounted such that the connector main body rises from the surface of the circuit wiring board via, for example, a board connection leg (hold down) joined to the circuit wiring board, and is provided on the connector main body of the electrical connector. A signal transmission medium is inserted inward from the insertion opening, and electrical connection is made.

  Among such electrical connectors, in a so-called non-Zif type electrical connector, a positioning portion comprising a notch-shaped recess, for example, at a terminal portion on the insertion side of a signal transmission medium inserted toward the inside And an automatic locking mechanism that maintains the insertion state of the signal transmission medium by engaging a lock part provided on the electrical connector side with a positioning part provided on the signal transmission medium side. Often adopted.

  On the other hand, in recent years, in this type of conventional electrical connector described in Patent Document 1 below, a contact pressure between a contact group held in the connector and each land portion of a signal transmission medium (FPC) is obtained. A configuration is being adopted in which a lock lever that prevents a signal transmission medium from falling off even with a small contact load is attached without using a slider. However, in such a configuration, since the lock portion provided in the connector main body is formed by a separate member, the entire connector tends to be expensive due to an increase in the number of parts. In addition, since the lock portion is engaged with the signal transmission medium by its own weight, there is a problem that a sufficient holding force for the signal transmission medium cannot be obtained.

  Further, in another electrical connector described in Patent Document 2 below, the signal transmission medium (FPC / FFC) is elastically pressed against the reinforcing metal fittings attached to both ends of the housing and soldered to the circuit wiring board. By providing the elastic support piece that supports the signal transmission medium, it is possible to prevent the signal transmission medium from being displaced. However, since the acting direction of the pressing force by the elastic support piece and the soldering portion of the reinforcing bracket are in a positional shift relationship, if the lock member release operation is repeated many times, it is continuously added to the connector body. The releasing operation force may affect the mounting state of the connector main body, and may cause the electrical connection to become unstable.

  In the following, it is assumed that the surface of the circuit wiring board (not shown) extends in a horizontal state, the direction in which the connector main body 11 rises from the surface of the circuit wiring board is “upward”, and the connector main body 11 The direction opposite to the rising direction is defined as “downward”. Further, the elongated extending direction of the insulating housing 11a constituting the connector main body 11 is defined as “connector longitudinal direction”, and the direction orthogonal to the “connector longitudinal direction” and “vertical direction” is defined as “front-rear direction”. Direction.

  Here, the above-described insulating housing 11a has a bottom wall surface facing a printed wiring board (not shown), and is a pair of rising wall surfaces that face each other from both sides in the front-rear direction on the bottom wall surface. An upper wall surface having a front end surface and a rear end surface, and connecting the upper sides of the front end surface and the rear end surface, which are the rising wall surfaces, extends above the bottom wall surface.

  An insertion opening 11b into which a signal transmission medium PB such as a flexible flat cable (FFC) and a flexible printed circuit board (FPC) described later is inserted is elongated along the connector longitudinal direction on the upper wall surface of the insulating housing 11a. It is formed to have a slit shape. The insertion opening 11b forms a hollow medium insertion passage that extends downward inside the insulating housing 11a and receives the terminal portion of the signal transmission medium PB. Then, the terminal portion of the signal transmission medium PB is arranged at a position above the insertion opening 11b so as to stand downward so as to be substantially orthogonal to the surface of the circuit wiring board (not shown). The terminal portion of the signal transmission medium PB is inserted into the medium insertion path of the electrical connector 10 through the insertion opening 11b as shown in FIG.

  According to such an insertion structure from above the signal transmission medium PB, when the signal transmission medium PB is inserted into the insertion opening 11b of the connector main body 11, the position of the insertion opening 11b and the signal transmission medium PB is determined. The relationship is easily observed from the upper side, and the insertion operation of the signal transmission medium PB is easily and accurately performed, and the state after insertion of the signal transmission medium PB is ensured satisfactorily.

[Insulating housing and conductive contact]
As described above, in particular, the conductive contact as shown in FIG. 7 is provided inside the insulating housing 11a into which the terminal portion of the signal transmission medium PB such as a flexible flat cable (FFC) or a flexible printed circuit board (FPC) is inserted. The (conductive terminal) 12 is disposed so as to extend in the vertical direction along the medium insertion path. A large number of the conductive contacts 12 are attached in a multipolar shape at a predetermined pitch interval along the connector longitudinal direction of the insulating housing 11a, and the conductive contacts 12 are arranged in a medium insertion passage of the insulating housing 11a. While having the flexible beam part 12a, the lower end part of the flexible beam part 12a is provided with the connection terminal part 12b which contacts a circuit wiring board (illustration omitted).

  The connection terminal portion 12b provided at the lower end portion of each conductive contact 12 extends toward the rear side (the right side in FIG. 7) and protrudes outward from the insulating housing 11a. The (rear end portion) is soldered to a conductive path (not shown) formed on the surface of a circuit wiring board (not shown). Further, from the inner end side portion of the connection terminal portion 12b opposite to the solder joint portion, the above-described flexible beam portion 12a is bent in a substantially right angle and extends in a cantilever manner. The flexible beam portion 12a extends so as to rise upward along the medium insertion path of the insulating housing 11a, and a terminal portion of the signal transmission medium PB is formed on the upper portion of the flexible beam portion 12a. The contact portion 12c is formed in contact with the terminal portion PB2 (see FIG. 4) provided in the contact portion.

[About Lock Unit Member (Holddown)]
Further, a pair of hold-downs 13 and 13 as lock unit members formed by bending a thin plate-like metal member are disposed at both end portions of the insulating housing 11a in the connector longitudinal direction. Each of these hold downs (lock unit members) 13 has a base frame plate 13a that surrounds both end portions of the insulating housing 11a in the connector longitudinal direction from the outer side in a substantially U-shaped plane. A pair of board connecting legs 13b and 13b projecting in the front and rear directions are provided on the front and back portions of the lower edge of 13a, respectively, and on the side surface of the lower edge of the base frame plate 13a. An integrated board connection leg portion 13c is provided to protrude outward in the connector longitudinal direction.

  Each of the board connecting legs 13b, 13b, 13c is formed of a plate-like member that is bent at a substantially right angle from the lower end edge of the above-described base frame plate 13a and protrudes outward, and its tip end portion extends substantially horizontally. It is formed to come out. The leading end portions of the board connection legs 13b, 13b, 13c are soldered to the connection parts (not shown) formed on the surface of the circuit wiring board (not shown), thereby The entire electrical connector 10 is fixed on the circuit wiring board.

  On the other hand, a plurality of plate-like fixing pieces 13d are formed on the upper edge portion of the base frame plate 13a of the hold-down (lock unit member) 13 described above so as to protrude upward. The entire hold down 13 is fixed to the insulating housing 11a by press-fitting the piece 13d into the insulating housing 11a.

  Next, in the terminal portion of the signal transmission medium PB inserted into the connector main body 11 as described above, the tip side exposed portion corresponds to the conductive contact 12 particularly as shown in FIG. Thus, terminal portions PB2 are formed at a predetermined pitch interval in the width direction, and positioning portions PB1 formed of notch-shaped concave portions are formed at the edge portions on both sides in the width direction. When the signal transmission medium PB is inserted into the electrical connector 10, the locking portion 14 provided on the electrical connector 10 side is engaged with the positioning part PB1 provided on the signal transmission medium PB. The insertion state of the signal transmission medium PB is held by such engagement of the locking lock portion 14.

  The locking lock 14 at this time is formed integrally with the hold-down (lock unit member) 13 disposed at both end portions in the connector longitudinal direction as described above, and is in the form of a beam provided so as to be elastically displaceable. It is provided in a part of the elastic lock link member 14a made of a member. The elastic lock link member 14a is cantilevered downward from the upper end portion on the back side of the hold down (lock unit member) 13 described above and integrally extends.

More specifically, the upper end portion constituting the base portion of the elastic lock link member 14a once bends from the upper end portion of the rising wall surface on the back side of the hold down (lock unit member) 13 to the front side of the connector. And is folded back toward the outer side in the connector longitudinal direction. And the main-body part which makes | forms the strip | belt-plate shape of the said elastic lock link member 14a is extended below from the folding | turning part 14c to the outward side. Folded portion 14c of the outward side provided at the upper portion of such an elastic lock link member 14a is made to swing fulcrum of the elastic lock link members 14a, downward from the swing fulcrum of its upper side A band plate-like main body portion extending in a cantilevered manner is formed as an oscillating member that can be elastically displaced. In the elastic lock link member 14a, the locking lock portion 14 described above is integrally provided at an intermediate position near the lower portion that is the swinging side portion of the band plate-like main body portion.

  At this time, the outward folding portion 14c including the upper oscillating fulcrum of the elastic lock link member 14a described above is configured to be folded back in the horizontal plane in consideration of the material cost to be used. However, the flexibility of the elastic lock link member 14a can be improved by adopting a structure in which the folded portion 14a is folded directly from the upper end side toward the lower side.

  Further, at the base end portion on the upper end side of the elastic lock link member 14a, the strip-like main body portion of the elastic lock link member 14a from the outward folded portion 14c having the folded structure in the horizontal direction as described above. Is extended downward and bent at a substantially right angle toward the front side of the connector from the lower end portion of the band plate-shaped main body portion, that is, the position corresponding to the lower side of the medium insertion passage described above. Has been made. And the locking lock part 14 mentioned above is arrange | positioned in the position a little above the lower end bending part of the elastic lock link member 14a.

  The locking lock portion 14 is formed of a substantially triangular hook-like member protruding from the side edge portion of the elastic lock link member 14a toward the connector front side so as to be bent at a substantially right angle. 11a is arranged so as to protrude toward the inside of the medium insertion path. The lower end edge corresponding to the base of the triangle that forms the outer shape of the locking lock portion 14 is an engagement side, and the inner peripheral edge portion of the positioning portion PB1 provided in the signal transmission medium PB described above. So that they can be engaged. Further, from the top portion provided on the protruding side portion of the engagement side of the locking lock portion 14, the guide side having a guide function for the positioning portion PB1 of the signal transmission medium PB described above is inclined upward. After the terminal portion of the signal transmission medium PB inserted into the electrical connector 10 rides on the guide side of the locking lock portion 14, the positioning portion of the signal transmission medium PB is extended. The locking lock portion 14 is engaged with the PB1.

That is, when the terminal portion of the signal transmission medium (FFC or FPC) PB is inserted into the medium insertion passage through the medium insertion opening 11b as shown in FIGS. When the terminal portion of the signal transmission medium PB comes into contact with the guide side and the locking lock portion 14 is pressed rearward, the elastic lock link member 14a extending in the substantially vertical direction in the initial state is It is bent and elastically displaced so as to be pushed rearward about the swing fulcrum. As a result, the locking portion 14 moves so as to be retracted rearward from the medium insertion path, and the terminal portion of the signal transmission medium PB continues to descend without any trouble. Furthermore, when the terminal portion of the signal transmission medium PB is pushed downward and the positioning portion (notch-shaped recess) PB1 reaches the locking lock portion 14, the lower end side engagement side of the locking lock portion 14 is The elastic lock link member 14a is swung so as to fall into the positioning portion PB1 of the signal transmission medium PB by the elastic restoring force of the elastic lock link member 14a. As a result, the locking lock portion 14 is engaged with the positioning portion PB1 of the signal transmission medium PB, and the insertion state of the signal transmission medium PB is maintained.
[Unlock mechanism]
The unlocking mechanism has a function of releasing the locking lock portion 14 engaged with the positioning portion PB1 of the signal transmission medium PB as described above, and unlocking for performing such unlocking operation is performed. An operation unit 14b is provided. In other words, as described above, the elastic lock link member 14a is bent so as to form a substantially L-shaped side surface from the lower position of the locking lock portion 14 provided in the middle of the elastic lock link member 14a and extends substantially horizontally to the front side of the connector. However, the front-side extended end portion of the elastic lock link member 14a is connected to the lower end portion of the lock release operation portion 14b.

  As described above, the unlocking operation portion 14b is arranged so as to protrude upward from the lower end portion which is a connecting portion with the elastic lock link member 14a, but is formed so as to be integrated with the insulating housing 11a. The unlocking operation portion 14b is arranged so that the outer surface forms a part of the outer surface from the upper wall surface of the insulating housing 11a to the front wall surface which is one of the rising wall surfaces. The moving operation of the operation unit 14b is configured to be pushed downward.

  More specifically, the unlocking operation portion 14b extends in a long shape along the connector longitudinal direction so as to connect the elastic lock link members 14a, 14a disposed at both ends in the connector longitudinal direction. The outer surface of the unlocking operation portion 14b is a part of the outer surface of the connector, that is, from the front side (left side in FIG. 8) of the medium insertion opening 11b to the front end surface on the front side of the connector. It arrange | positions so that the connector outer surface over half may be formed.

  Further, the unlocking operation portion 14b is integrally connected to the insulating housing 11 via a pair of swing arms 14b1 and 14b1 at both end portions in the connector longitudinal direction. The pair of swing arms 14b1 and 14b1 is formed of a plate-like member that forms the outer surface of the connector on both outer sides of the insertion opening 11b, and is disposed in the front portion of the connector (the left portion in FIG. 8). It is configured to extend toward the rear side from the unlocking operation portion 14b and to form an elastic flexible member that integrally couples both the members 14b and 11a. By such a pair of swinging arms 14b1 and 14b1, the unlocking operation unit 14b is held so as to be elastically displaceable in the vertical direction, and the upper wall surface, which is a pressed surface of the unlocking operation unit 14b, is lowered by the fingertip of the operator By being pushed in, particularly, as shown in FIG. 3 and FIG. 9, it is configured to be elastically displaced while slightly rotating downward.

  On the other hand, the elastic lock link member 14a connected to the lock release operation portion 14b is configured to swing in conjunction with the downward pushing operation of the lock release operation portion 14b, that is, the lock release operation. . More specifically, the elastic lock link member 14a extends from the lower position of the locking lock portion 14 to the front side of the connector as described above, and its extended end is connected to the lower end portion of the lock release operation portion 14b. It is made to the composition. Therefore, when the unlocking operation portion 14b moves so as to be pushed downward by the unlocking operation, the elastic lock link member 14a is elastically displaced, particularly as shown in FIGS. The locking lock portion 14 is moved so as to rotate to the rear side of the connector (right side in the figure), whereby the locking lock portion 14 is detached from the positioning portion PB1 of the signal transmission medium PB.

  That is, from the state in which the signal transmission medium PB is inserted and held as described above, that is, from the state in which the locking portion 14 is engaged with the positioning portion PB1 of the signal transmission medium PB and the insertion state of the signal transmission medium PB is maintained. When the assembly operator's operating force is applied to the unlocking operation portion 14b on the lower side, the elastic lock link member 14a swings counterclockwise in FIGS. 8 and 9 against its own elastic force. Thus, the locking portion 14 provided on the elastic lock link member 14a is retracted rearward from the medium insertion path and is released from the positioning portion PB1 of the signal transmission medium PB. As a result, the signal transmission medium PB is opened, and the signal transmission medium PB can be removed upward.

[Unlock movement restrictions]
At this time, the insulating housing 11 has a swing restricting surface 11c that faces the unlocking operation portion 14b described above from the rear side. As described above, the swing restricting surface 11c is formed from an inclined stopper surface with which the lower end edge portion of the unlocking operation portion 14b comes into contact when the unlocking operation portion 14b is pushed downward during the unlocking operation. Yes. That is, the lock release operation part 14b is displaced so as to fall forward as the elastic lock link member 14a swings due to the lock release operation (see FIG. 9), but when such a lock release operation is performed over a predetermined amount. In this case, the lower end portion of the unlocking operation portion 14b comes into contact with the rocking regulation surface 11c of the insulating housing 11 described above, and further unlocking operation is restricted, and the unlocking operation portion 14b is excessively operated. It is configured so that there is nothing.

  As described above, in this embodiment, the lock release mechanism having the lock release operation portion 14b, the elastic lock link member 14a, and the locking lock portion 14 has a bottom wall surface and a rear wall from the front end surface that is one of the rising wall surfaces of the insulating housing 11a. It arrange | positions so that it may wrap around along the circumference | surroundings of the said insulating housing 11a over an end surface. Therefore, the medium insertion path of the signal transmission medium PB is formed in the central portion of the insulating housing 11a without being disturbed by the lock release mechanism. Further, since the span length of the elastic lock link member 14a is ensured to be elongated along the circumference of the medium insertion path of the signal transmission medium PB, the entire connector can be reduced in size without deteriorating the connector function. Easy to do.

  Further, in this embodiment, the elastic lock link member 14a and the locking lock portion 14 constituting the lock release mechanism are integrated with the hold-down (lock unit member) 13 having the board connection legs 13b, 13b, 13c. Therefore, high productivity can be obtained.

  Furthermore, since hold downs (lock unit members) 13 having a lock release mechanism are arranged at both end portions in the connector longitudinal direction, even for electrical connectors having different connector lengths and contact core numbers (pole numbers). The lock unit member having the same structure can be shared.

  Furthermore, according to this embodiment, since the unlocking operation part 14b is arranged so as to wrap around from the upper wall surface to the front end surface of the insulating housing 11, the medium insertion path of the signal transmission medium PB is provided with the unlocking operation part. It is formed without being obstructed by 14b, and the miniaturization of the entire connector is further facilitated.

  Although the invention made by the present inventor has been specifically described based on the embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. Needless to say.

  For example, the elastic lock link member according to the present invention may be arranged so as to wrap around from the back side (rear end surface side) on the circuit wiring board side to the front side (front end surface side), contrary to the above-described embodiment. .

  Further, the present invention is not limited to the vertical insertion type electrical connector as in each of the above-described embodiments, and can be similarly applied to a horizontal insertion type electrical connector.
