Description

  The present invention relates to a connector for conductively connecting a flat conductor such as an FPC and a substrate.

In recent years, electrical devices such as smartphones have been reduced in size and thickness, and at the same time, on-board functions such as camera shooting functions have become more sophisticated and multifunctional. In addition, for connectors used in such electrical devices, there is an increasing need for smaller size and lower height in order to increase the mounting density on the board.
A connector used in the above-mentioned electrical equipment, which is mounted on a board and electrically connects a flat conductor such as an FPC (Flexible printed circuit) or FFC (Flexible flat cable) and the board, includes a plug and a socket. What consists of two pieces is known. In this connector, a flat conductor or a substrate is connected to each of a plug and a socket, and the flat conductor and the substrate are electrically connected by stacking them.
However, in this type of connector, since the plug and the socket are fitted so as to overlap with each other in the board thickness direction, it is difficult to reduce the size in the board thickness direction (height direction). Therefore, a one-piece connector is used to reduce the size in the height direction. This one-piece connector is mounted on a board, and a flat conductor can be inserted into the board for electrical connection with the board.
Some connectors include a slider (pressing member) for pressing and fixing the flat conductor against the contact portion of the terminal in order to electrically connect the terminal and the flat conductor (see Patent Document 1). There are also other actuators that are fixed by contacting the flat conductor and the contact portion of the terminal by rotating the actuator.

JP2004-348974

  However, the one-piece connector described above requires a step of operating a slider and an actuator in order to connect the flat conductor and the connector in a conductive manner and fix the flat conductor in this state to prevent the flat conductor from coming off. . Further, since the slider and the actuator are provided along the contact direction between the flat conductor and the contact portion of the terminal, the size of the connector is increased by the amount of those components. In particular, when the flat conductor and the terminal are arranged along the height direction of the connector, it is difficult to reduce the height direction.

  The present invention has been made to solve the above problems. That is, an object of the present invention is to provide a connector that can prevent the flat conductor from coming off without increasing the number of work steps. It is another object of the present invention to provide a connector that can be securely connected to a flat conductor while being small.

In order to achieve the above object, the present invention is configured as follows.
That is, the present invention includes a terminal portion that is conductively connected to a flat conductor, and a connector main body having an insertion port for the flat conductor, and the connector main body includes a housing that holds the terminal portion, and a metal plate. A connector in which the terminal portion is electrically connected to the flat conductor by inserting the flat conductor between the terminal portion and the shell from the insertion port. A terminal group and a second terminal group, wherein the first terminal group includes a plurality of terminals having a first contact portion in contact with the flat conductor arranged in parallel; The terminal group of 2 includes a plurality of terminals having a second contact portion in contact with the flat conductor arranged in parallel, and the shell includes the first contact portion and the second contact portion. It has an upper surface part to cover, and the surface of the upper surface part is the outer shape of the connector. And the flat conductor is pressed and contacted by the first contact portion and the second contact portion on the back surface, and the first contact portion and the second contact portion are in the pressed state in the pressed state. Conductive connection with a conductor is provided, and the housing includes an elastic lock piece that is engaged with the flat conductor in a state where the first contact portion, the second contact portion, and the flat conductor are conductively connected. A connector is provided.

  In the present invention, the shell is provided so as to cover the first contact portion and the second contact portion, and this contact portion is electrically connected to the flat conductor in a state where the flat conductor is pressed against the shell. The flat conductor pressed by the contact portion can be received by the shell. Accordingly, the flat conductor can be sandwiched between the contact portion and the shell to prevent it from coming off, and the contact portion and the flat conductor can be securely connected to each other. Further, by providing the shell with a metal plate, the shell can be formed thinner while maintaining the rigidity of the shell so that the flat conductor can be sandwiched between the contact portions. Therefore, it is possible to reduce the size of the connector in the height direction by reducing the thickness of the shell.

  In the present invention, the housing includes an elastic lock piece that is engaged with the flat conductor in a state where the first contact portion and the second contact portion are conductively connected to the flat conductor. The disconnection of the mold conductor from the connector can be more reliably suppressed, and a connector with high connection reliability can be obtained.

  The elastic lock piece can be formed more easily by arranging it in parallel with the terminal, for example, and providing it on the housing. Further, by forming the elastic lock piece in a cantilever shape, for example, the elastic lock piece can be locked to the flat conductor with a simpler structure. Furthermore, for example, a locking portion is formed on this cantilevered elastic locking piece, and the flat conductor is inserted into the connector so that the locking portion is pressed by the flat conductor and elastically displaced away from the flat conductor. It shall be. And, by adopting a structure in which the locking portion is hooked and locked to a locking receiving portion such as a locking hole or a notch formed in the flat conductor, only the operation of inserting the flat conductor into the connector is possible. The elastic lock piece can be locked to the flat conductor. Therefore, the process of locking the connector to the flat conductor can be omitted.

  The shell has an upper surface portion covering the first contact portion and the second contact portion, a surface of the upper surface portion forms an outer shape of a connector, and the flat conductor is formed on the back surface of the first conductor. The contact portion is pressed and brought into contact with the second contact portion, and in this pressed state, the first contact portion and the second contact portion are electrically connected to the flat conductor. Therefore, for example, the shell is partially folded, and the entire height of the connector can be reduced as compared with the case where the same surface as the surface forming the outer shape of the connector is in conductive contact with the contact portion of each terminal. In addition, for example, by making the upper surface portion of the shell into a flat plate shape that maintains a flat plate surface, the overall height of the connector can be further reduced.

  In addition, when the contact portions of a plurality of terminals are arranged at the same position in the insertion direction of the flat conductor, and the flat conductor receives resistance from the plurality of terminals simultaneously, the flat conductor and the connector are fitted together. Will need more power. However, if the second contact portion of the present invention is to contact the flat conductor at an insertion position different from the first contact portion in the insertion direction of the flat conductor, It is possible to prevent the second terminal group from contacting the tip of the flat conductor inserted into the connector at the same time. By doing so, it is possible to disperse the resistance that the flat conductor receives from the terminal portion during insertion, and to fit the flat conductor to the connector with a smaller force.

  The elastic lock piece of the present invention includes a fixing portion fixed to the housing on the near side in the insertion direction of the flat conductor, and a substrate fixing portion connected to the fixing portion and fixed to the substrate. be able to.

  When inserting the flat conductor into the connector fixed to the board, for example, the flat conductor is inserted obliquely into the connector insertion slot, and a force is applied to the connector away from the board by the flat conductor. May be. However, the elastic lock piece has a fixing portion that is fixed to the housing just before the insertion direction of the flat conductor, and further has a substrate fixing portion that is connected to the fixing portion and fixed to the substrate. The housing can be securely fixed to the substrate on the front side in the insertion direction of the flat conductor. Therefore, even in the above case, the connector can be made difficult to peel off from the board.

  The housing of the present invention has a side wall portion in which a mounting recess is provided, and the shell has a housing fixing portion that is disposed inside the mounting recess and fixed to the housing. it can.

  If the housing fixing portion of the shell is fixed to the outside of the housing, the size of the connector as a whole increases by the amount that the housing fixing portion protrudes outward from the housing. In particular, if the housing fixing portion is fixed to the bottom surface side of the housing and attached so as to be inserted between the housing and the substrate, the height of the connector is increased by the height of the housing fixing portion. Therefore, the housing is provided with a mounting recess as in the present invention, and the housing fixing portion of the shell is inserted and fixed inside the mounting recess, so that the housing fixing portion does not protrude outside and the connector is entirely Thus, the shell can be securely fixed to the housing without increasing the size.

  The housing of the present invention has a back side wall portion arranged on the back side in the insertion direction of the flat conductor, and the shell is connected to the upper surface portion and a back plate portion along the wall surface of the back side wall portion. It can have.

In this way, when the shell is attached to the housing, the shell can be positioned by aligning the back plate portion with the back side wall portion, so that the attaching operation can be easily performed. In a state where the shell is attached to the housing, even if the shell and the housing are likely to be displaced from each other, the movement can be restricted by the contact between the back plate portion and the back side wall portion.
Further, the entire connector can be reduced in size by arranging the back plate portion along the plate surface of the back side wall portion so as not to create a large gap between the back plate portion and the back side wall portion. Further, for example, by arranging the back plate portion so as not to cover the terminal and exposing the substrate connecting portion of the terminal from the shell, the soldering operation of the substrate connecting portion to the substrate can be performed efficiently.

In the present invention, the elastic locking piece may be brought into contact with the shell by being engaged with a flat conductor to generate a contact sound.
According to the present invention, the operator can confirm that the elastic lock piece is locked to the flat conductor by the contact sound.

  The elastic lock piece according to the present invention includes a first extending portion extending along a direction in which a flat conductor is inserted into the connector body, a folded portion connected to the distal end side of the first extending portion, and the folded portion. And a second extending portion that extends along a direction in which the flat conductor is removed from the connector main body.

  By doing so, the spring length of the elastic lock piece can be extended inside the narrow housing. Thereby, the elastic lock piece can be sufficiently elastically deformed inside the housing, and a sufficient restoring force from the deformed state can be exhibited. Therefore, the flat conductor can be securely locked and prevented from coming off.

  The first extending portion of the present invention may have a step portion that bends in a direction away from the flat conductor inserted into the connector body.

  By doing so, even when the second extension portion is elastically deformed toward the first extension portion, it is difficult to cause a situation in which further elastic deformation is prevented by contacting the first extension portion. can do.

In the present invention, the elastic locking piece is brought into contact with the flat conductor at an insertion position different from at least one of the first contact portion or the second contact portion in the insertion direction of the flat conductor. Can do.
According to the present invention, it is possible to reduce the number of terminals that come into contact with the flat conductor simultaneously with the elastic locking piece when the flat conductor is inserted. Therefore, the resistance received simultaneously from the terminal portion and the elastic lock piece when inserting the flat conductor can be reduced, and the flat conductor can be inserted into the connector with a smaller force.

In the present invention, the first contact portions and the second contact portions can be alternately arranged in parallel.
According to the present invention, it is possible to evenly distribute the contact portions along the parallel direction without biasing the resistance acting on the flat conductor inserted into the connector from the terminal portion. Therefore, distortion and damage of the flat conductor due to partial strong resistance can be suppressed.

In the present invention, the terminals of the first terminal group and the terminals of the second terminal group can have the same shape.
According to the present invention, it is possible to provide a connector that is easy to manufacture without increasing the types of components. Further, the current value of each terminal can be easily made constant, and the entire terminal portion can be conductively connected to the substrate without deviation.

In the present invention, the insertion port is formed by an opening formed between the outer edge portion of the housing and the outer edge portion of the shell, and the outer edge portion of the shell is connected to the outer edge portion of the housing with a flat conductor. It can be provided on the back side in the insertion direction.
According to the present invention, since the operator can visually confirm the insertion port from the shell side, the flat conductor can be inserted into the connector without searching for the insertion port with a hand. Further, at that time, the contact surface of the flat conductor with the shell can be along the outer edge of the shell, and can be inserted into the connector through the insertion port in an inclined state. Therefore, even if there are other electronic components in the periphery and it is difficult to insert the flat conductor parallel to the substrate and insert it into the connector, the flat conductor can be easily inserted.

In the present invention, in the insertion direction of the flat conductor, the distance from the outer edge portion of the shell to the first contact portion and the second contact portion is determined from the outer edge portion of the housing to the first contact portion. The distance can be set shorter than the distance to the second contact portion.
It may be difficult and difficult to align the flat conductor into the insertion port of the small connector. This is particularly difficult when a flat conductor is inserted obliquely into the insertion slot, for example. Therefore, the distance from the outer edge portion of the shell to the contact portion is formed shorter than the distance from the outer edge portion of the housing to the contact portion. By doing so, the flat conductor inserted into the connector from the insertion port can be conductively connected to the contact portion only by moving a shorter distance while having the function of guiding the flat conductor in the housing.

  In the present invention, the elastic lock piece and the housing can be formed as an integral molded body. According to this, it is not necessary to prepare another component as the elastic lock piece, and the number of components can be reduced.

  In the present invention, the elastic lock piece can be formed of a metal piece. According to this, it is possible to obtain an elastic lock piece that has higher rigidity and is not easily damaged even if it receives a reaction force from a flat conductor.

  In the present invention, the terminal portion can be integrally formed with the housing. By doing so, a step of inserting the terminal portion into the housing is not required, so that a connector that is easier to manufacture can be obtained.

  In the present invention, the flat conductor may have a shield layer, and the shell may have a contact portion with the shield layer. According to this, by grounding the shell to the substrate, it is possible to take measures against EMI of noise generated by the flat conductor. Therefore, a connector that can be used for high-speed transmission of high-frequency signals can be realized.

  According to the connector of the present invention, the flat conductor can be prevented from coming off without increasing the number of work steps. By doing so, the efficiency of the fitting work can be increased. In addition, according to the connector of the present invention, it is possible to reliably establish a conductive connection with a flat conductor while having a low profile. Therefore, a connector with high connection reliability can be realized without separately providing a thick part in the height direction. Furthermore, according to the connector of the present invention, the flat conductor can be fitted with a smaller force. Therefore, it is possible to suppress the damage caused by applying a strong force to the miniaturized connector and realize a connector that can be easily fitted.

In the description, the board 2 side in the height direction Z is referred to as “lower side” and the connector 1 side is referred to as “upper side”. However, these do not limit the fitting direction of the connector 1 or the mounting method on the board 2. 7 shows a right side view of the elastic lock piece 7, the left side view is represented symmetrically with the right side view.

Embodiment [FIGS. 1 to 12]:
The connector 1 includes a connector main body 4 and a terminal portion 5 as shown in FIGS. The connector body 4 includes a housing 6, an elastic lock piece 7, and a shell 8.

  On one front wall portion 6a, a step portion 6d that forms an insertion port 9 for inserting the flat conductor 3 into the connector 1 is formed. The step portion 6d is formed one step lower than the upper surface of the other rear wall portion 6b and the upper surfaces of the two side wall portions 6c and 6c. The upper end of the stepped portion 6d is disposed at the approximate center of the housing 6 in the height direction Z.

  A housing portion 6e for housing a later-described terminal portion 5 is provided inside the housing 6. The terminal portion 5 is elastically deformable mainly along the height direction Z in the housing portion 6e.

  An attachment recess 6f is provided on the side of the substrate 2 in the side wall portions 6c, 6c of the housing 6. The mounting recess 6f is provided from the rear end side to the front side of the side wall portion 6c of the housing. However, since the stopper portion 6h is provided in front of the mounting recess 6f, the mounting recess 6f is not provided over the entire length in the front-rear direction Y. A housing fixing portion 8b1 of the shell 8 described later is inserted into the mounting recess 6f.

(Terminal part)
The terminal portion 5 is fixed to the housing 6. As a fixing method, in the present embodiment, the housing 6 and the terminal portion 5 are formed as an integral molded body by insert molding. Therefore, the process of attaching the terminal part 5 to the housing 6 becomes unnecessary, and the terminal part 5 can be provided in the housing 6 more easily. As shown in FIGS. 1, 4, and 5, the terminal unit 5 includes a first terminal group 5 a and a second terminal group 5 b that are in contact with the flat conductor 3.

  The first terminal group 5 a includes a plurality of terminals 10 that are fixed to the rear wall portion 6 b without the stepped portion 6 d and arranged in parallel along the width direction X of the housing 6.

  The second terminal group 5 b has a plurality of terminals 10 that are fixed to the front wall portion 6 a with the stepped portion 6 d and arranged in parallel along the width direction X of the housing 6. The number of terminals 10 of the first terminal group 5a and the number of terminals 10 of the second terminal group 5b are the same number, specifically, five in this embodiment.

  The terminals 10 of the first terminal group 5a and the terminals 10 of the second terminal group 5b are both made of a conductive metal and have the same shape and the same size. By sharing the terminal 10 between the first terminal group 5a and the second terminal group 5b, different terminals 10 are not required, and the manufacturing cost can be reduced. Therefore, the resistance of each terminal 10 becomes the same, and it is not necessary to take special measures to make the current values uniform.

  The terminal 10 includes a board connecting portion 10a, a fixing portion 10b, an elastic piece portion 10c, and a contact portion 10d. The terminals 10 of the first terminal group 5a are cantilevered from the rear wall 6b of the housing 6 and the terminals 10 of the second terminal group 5b are cantilevered from the front wall 6a of the housing 6 to the inside and outside of the housing 6, respectively. It extends like a beam.

  A board connecting portion 10 a extending to the outside of the housing 6 is provided on one end side of the terminal 10 and is fixed to the board 2 by soldering.

  The fixed portion 10b is a fixed portion with respect to the housing 6, is continuous with the substrate connecting portion 10a, and is formed in a flat plate shape. The fixed portion 10b is formed of a vertical piece 10b1 and a horizontal piece 10b2. The vertical piece 10b1 extends along the height direction Z from the board connecting portion 10a side, and the plate surface is substantially parallel to the wall surface 6a1 of the front wall portion 6a of the housing 6 and the wall surface 6b1 of the rear wall portion 6b. Is provided. The upper end of the vertical piece 10 b 1 is located at the approximate center in the height direction Z of the housing 6. The horizontal piece 10b2 is provided so as to be continuous with the upper end of the vertical piece 10b1 and have a plate surface substantially parallel to the substrate 2. And the horizontal piece part 10b2 in the terminal 10 of the 1st terminal group 5a penetrates the rear wall part 6b of the housing 6, and the horizontal piece part 10b2 in the terminal 10 of the 2nd terminal group 5b penetrates the front wall part 6a. The terminals 10 are fixed to the housing 6.

  The elastic piece portion 10c is continuous with the fixed portion 10b and is formed in a flat plate shape. The elastic piece portion 10c is elastically deformed along the height direction Z of the connector 1 with a fixed portion (fixed portion 10b) with the front wall portion 6a or the rear wall portion 6b on the fixed side as a fulcrum.

  The contact portion 10 d is formed continuously with the elastic piece portion 10 c and is a portion that is conductively connected to the flat conductor 3. The contact portion 10d is formed with a narrower terminal width than the elastic piece portion 10c so as to be soft and elastically deformable. A first contact portion 10d1 is formed at the terminal 10 of the first terminal group 5a at the approximate center of the contact portion 10d bent in a mountain shape along the front-rear direction Y. Similarly, a second contact portion 10d2 is formed at the terminal 10 of the second terminal group 5b. The contact portions 10d1 and 10d2 are electrically connected to the flat conductor 3, respectively. The terminal 10 has an inclined portion 10d3 on the tip side of the contact portions 10d1 and 10d2. The inclined portion 10d3 is formed to be curved so that the inclination angle gradually increases toward the distal end side of the terminal 10. And the front-end | tip is formed so that it may become a position substantially the same as the elastic piece part 10c in the height direction Z of the connector 1, ie, a position lower than the upper surface of the step part 6d of the front wall part 6a.

  The terminals 10 of the first terminal group 5a and the terminals 10 of the second terminal group 5b are alternately arranged along the width direction X. Thereby, in the terminal part 5, the 1st contact part 10d1 and the 2nd contact part 10d2 are arrange | positioned at the different position in the front-back direction Y at zigzag form. By arranging the terminals 10 in a staggered manner in this way, the pitch between the adjacent first contact portions 10d1 and the second contact portions 10d2 is reduced, and at the same time, the interval between the substrate connection portions 10a and 10a is increased. Can do. Therefore, it is possible to obtain the terminal portion 5 which has a narrow pitch and is easy to be soldered to the substrate 2 and easy to mount.

[Elastic lock piece]
The elastic lock piece 7 is for locking the flat conductor 3 so as not to come out of the connector 1. The elastic lock piece 7 is formed of a metal piece and is provided at both side positions of the second terminal group 5 b in the width direction X of the housing 6. The insert 6 is integrally molded and fixed to the front wall 6 a having the step 6 d of the housing 6 in the same manner as the terminal 5. Thereby, the attachment process to the housing 6 of the elastic lock piece 7 can be skipped.

  As shown in FIGS. 7 and 9 to 12, the elastic lock piece 7 includes a substrate fixing portion 7 a, a fixing portion 7 b, an elastic piece portion 7 c, and a locking portion 7 d.

  The board fixing portion 7 a is provided on one end side of the elastic lock piece 7 and is fixed by being soldered to the board 2. The board fixing part 7a is fixed to the board 2 on the side of the front wall part 6a where the insertion port 9 for the flat conductor 3 to the connector 1 is provided.

The fixing portion 7b is formed continuously with the substrate fixing portion 7a, and has a vertical piece portion 7b1 and a horizontal piece portion 7b2 which are bent in a crank shape.
The vertical piece 7 b 1 extends in the height direction Z and is formed so that the plate surface is substantially parallel to the wall surface 6 a 1 of the front wall portion 6 a of the housing 6. The horizontal piece 7b2 is formed so as to be bent from the upper end of the vertical piece 7b1 so that the plate surface is substantially parallel to the substrate 2. Further, the horizontal piece 7 b 2 passes through the front wall 6 a of the housing 6 and is fixed to the housing 6.
When the flat conductor 3 is inserted into the connector 1 fixed to the board 2, the flat conductor 3 is inserted obliquely into the insertion port 9 of the connector 1, and the board 1 is connected to the connector 1 by the flat conductor 3. A force may be applied in a direction away from 2. However, the connector 1 has the fixing portion 7b to which the elastic lock piece 7 is fixed to the housing 6 before the insertion direction of the flat conductor 3 as described above, and further to the board 2 before the insertion direction of the flat conductor 3. It has the board | substrate fixing | fixed part 7a fixed with respect to it. Therefore, the housing 6 can be securely fixed to the board 2 on the front side in the insertion direction of the flat conductor 3 by the elastic lock piece 7, so that the connector 1 is hardly peeled off from the board 2 even in the above case. be able to.

  The elastic piece portion 7c is continuous with the fixed portion 7b and is formed in a flat plate shape. And it has the 1st expansion | extension part 7c1, the folding | returning part 7c2, and the 2nd expansion | extension part 7c3.

  The first extending portion 7c1 extends along the front-rear direction Y from the front wall portion 6a having the step portion 6d in the housing 6 toward the rear wall portion 6b not having the step portion 6d. Further, the first extending portion 7c1 is provided with a step portion 7c5 that is hung from the front wall portion 6a side to the rear wall portion 6b side and is stepped down in a crank shape. The rear wall 6b side of the stepped portion 7c5 is provided away from the second extending portion 7c3 as compared to the front wall 6a side. A through hole 7c4 is formed on the front wall 6a side of the step 7c5.

  The folded portion 7c2 extends from the end on the rear wall 6b side toward the side closer to the flat conductor 3 inserted in the fitting chamber 6g in the first extending portion 7c1, and is bent in a substantially U shape. Formed. And it connects to the 2nd expansion part 7c3.

  The second extending portion 7c3 extends along the front-rear direction Y from the rear wall portion 6b side toward the front wall portion 6a side. The second extension 7c3 is provided at the same position in the width direction X as the first extension 7c1, and the first extension 7c1 and the second extension 7c3 overlap in the height direction Z. It is done.

  The elastic piece portion 7c as described above is elastically deformed along the height direction Z of the connector 1 with a fixed portion (fixed portion 7b) to the front wall portion 6a on the fixed side as a fulcrum. Further, the spring length can be extended inside the narrow housing 6 by making the shape folded inside the housing 6 as described above. Thereby, when pressed by the flat conductor 3, the elastic piece 7c can be sufficiently elastically deformed. Further, when the flat conductor 3 is further inserted into the inner side of the fitting chamber 6g and the locking receiving portion 3a of the flat conductor 3 reaches the locking portion 7d, the elastic piece portion 7c exhibits a sufficient restoring force. Thus, the locking portion 7d is inserted into the locking receiving portion 3a.

  A locking portion 7d is provided at the tip of the elastic piece portion 7c. The locking part 7d has a vertical piece part 7d1 along the height direction Z, a bent part 7d2, and an inclined part 7d3. The bent portion 7d2 is inserted differently in the front-rear direction Y from the first contact portion 10d1 in the terminal 10 of the first terminal group 5a and the second contact portion 10d2 in the terminal 10 of the second terminal group 5b. Provided in position. Thereby, it is possible to prevent the first contact portion 10d1 and the second contact portion 10d2 from coming into contact with the tip of the flat conductor 3 inserted into the connector 1 at the same time. By doing so, the resistance that the flat conductor 3 receives from the terminal portion 5 at the time of insertion can be dispersed, and the flat conductor 3 can be fitted to the connector 1 with a smaller force.

  The elastic lock piece 7 is formed so that the plate width is wider than the terminal 10 in each part over the entire length. Thereby, it is hard to elastically deform and the restoring force when pressed is strengthened. Further, the distal end of the elastic lock piece 7 is positioned at substantially the same position as the second extending portion 7c3 in the height direction Z of the connector 1, that is, lower than the upper surface of the step portion 6d of the front wall portion 6a. Formed as follows.

〔shell〕
The shell 8 is formed of a thin metal plate and includes an upper surface portion 8a, a side surface portion 8b, a substrate fixing portion 8c, and a back plate portion 8f, as shown in FIGS.

  The upper surface portion 8a is formed in a substantially rectangular shape and is provided so as to cover the first contact portion 10d1 and the second contact portion 10d2. The front surface 8a2 of the upper surface portion 8a forms the outer shape of the connector 1, and the flat conductor 3 is pressed and brought into contact with the back surface 8e by the first contact portion 10d1 and the second contact portion 10d2. The first contact portion 10d1 and the second contact portion 10d2 are electrically connected to the flat conductor. Therefore, for example, the shell 8 is partially folded, and the entire surface of the connector 1 is reduced compared to the case where the same surface as the surface forming the outer shape of the connector 1 is in conductive contact with the contact portions 10d1 and 10d2 of each terminal 10. Can be turned upside down. Further, the shell 8 is formed in a flat plate shape that maintains a flat plate surface, which contributes to a reduction in the overall height of the connector 1. Two substantially rectangular through-holes 8a1 are formed in the upper surface portion 8a, and are provided above the bent portion 7d2 of the elastic lock piece 7 described above.

  Two side portions 8b are provided at both ends in the width direction X of the upper surface portion 8a. Therefore, the shell 8 has four side portions 8b. Further, the side surface portion 8 b is provided so as to cover the wall surface 6 c 1 of the side wall portion 6 c in the housing 6.

  A housing fixing portion 8b1 is provided at the lower end of the side surface portion 8b. The housing fixing portion 8b1 is bent from the lower end of the side surface portion 8b in a direction parallel to the substrate 2 and has a substantially rectangular bottom surface. The housing fixing portions 8b1 and 8b1 on one side in the width direction X and the housing fixing portions 8b1 and 8b1 on the other side are provided to face each other. The housing fixing portions 8b1 and 8b1 on the one side are disposed inside the mounting recess 6f on the one side of the housing 6. Similarly, the other-side housing fixing portions 8b1 and 8b1 are disposed inside the other-side mounting recess 6f. Accordingly, the two housing fixing portions 8 b 1 and 8 b 1 are arranged in one mounting recess 6 f and the shell 8 is held against the housing 6.

  A guide edge 8b2 that is inclined with respect to the width direction X and the front-rear direction Y is formed on the front end side of each housing fixing portion 8b1 and on the center side in the width direction X. By providing the guide edge 8b2, the length of the housing fixing portion 8b1 in the width direction X becomes shorter toward the front end side, and the interval between the housing fixing portions 8b1 facing each other increases toward the front end side.

  The back plate portion 8f extends from the rear end portion of the upper surface portion 8a. The back plate portion 8f is provided along the wall surface of the rear wall portion 6b of the housing 6 so that a large gap is not formed between the rear plate portion 8f and the rear wall portion 6b. Therefore, compared to the case where a large gap is provided between the rear wall portion 6b of the housing 6 and the back plate portion 8f, it is possible to suppress the connector 1 from being enlarged in the front-rear direction Y as a whole.

  Further, the back plate portion 8f is provided short in the height direction Z so as not to interfere with the substrate connecting portion 10a of the terminal 10 of the first terminal group 5a and not to cover the substrate connecting portion 10a from above. By doing so, when the board connecting portion 10a is soldered to the board 2, the back plate portion 8f of the shell 8 does not get in the way, so that the soldering work can be performed efficiently.

  The housing 6 is accommodated in a space 8g formed by the upper surface portion 8a of the shell 8, the four side surface portions 8b and 8b, the back plate portion 8f, and the four housing fixing portions 8b1.

  The substrate fixing portion 8c is provided by bending outward between two side surface portions 8b, 8b provided on the same plane. Then, it is soldered to the substrate 2.

  The shell 8 forms an insertion port 9 for the flat conductor 3 between the shell 8 and the step 6 d of the housing 6 while being fixed to the housing 6. An outer edge portion 8d facing the step portion 6d is provided at the front end of the shell 8, and this outer edge portion 8d faces an extension line of the wall surface 6a1 of the front wall portion 6a toward the back side in the insertion direction of the flat conductor 3. It is formed by shifting from the position. As a result, the opening width on the insertion port 9 side in the insertion direction of the flat conductor 3 is greatly enlarged. Further, the distance between the height position along the horizontal direction of the step portion 6d and the back surface 8e of the upper surface portion 8a of the shell is substantially the same as the thickness of the flat conductor 3, so that the connector 1 as a whole has a low height. ing.

[Description of assembly method]
The housing 6, each terminal 10, and the elastic lock piece 7 are provided by insert integral molding as described above. When the shell 8 is fixed to the housing 6, first, the position of the front end of the shell 8 on the outer edge portion 8 d side is aligned with the rear wall portion 6 b side of the housing 6. Specifically, the front end of the housing fixing portion 8b1 is aligned with the rear end of the mounting recess 6f, and the housing fixing portions 8b1 and 8b1 are positioned on both sides of the bottom wall portion 6i located between the mounting recesses 6f and 6f in the housing 6. Adjust. A guide edge 8b2 is formed on the front end side of the housing fixing portion 8b1, and the interval between the housing fixing portions 8b1 facing each other is increased toward the front end side as described above, so that the bottom wall is formed between the guide edges 8b2 and 8b2. It becomes easy to insert the part 6i. In this state, the housing fixing portion 8b1 is slid into the mounting recess 6f, but the sliding movement can be guided by the guide edge 8b2. By doing so, the housing 6 is accommodated in the space 8 g of the shell 8.

  When the front end of the housing fixing portion 8b1 of the shell 8 comes into contact with the stopper portion 6h of the housing 6 by sliding movement, the movement of the shell 8 relative to the housing 6 can be restricted. Similarly, the movement of the shell 8 relative to the housing 6 can also be restricted by contacting the back plate portion 8 f of the shell 8 with the rear wall portion 6 b of the housing 6. By providing the stopper portion 6 h and the back plate portion 8 f, the shell 8 can be easily positioned with respect to the housing 6. Thus, by disposing the two housing fixing portions 8b1 inside one mounting recess 6f, the mounting operation of the shell 8 to the housing 6 is completed.

  Since the housing 6 can be disposed between the housing fixing portion 8b1 and the upper surface portion 8a by the above mounting method, the shell 8 is attached to the housing 6 as compared with the case where the shell 8 is simply put on the housing 6. Can be fixed firmly. In addition, since the housing 6 can be accommodated in the space 8g of the shell 8 by sliding the housing 6 on the shell 8 as described above, the housing fixing portion 8b1 is mounted after the shell 8 is put on the housing 6. Is not required to bend and insert into the mounting recess 6f. Therefore, the operation of attaching the shell 8 to the housing 6 can be performed more easily.

  If the shell 8 is likely to move forward with respect to the housing 6 with the shell 8 fixed to the housing 6, the housing fixing portion 8b1 of the shell 8 may come into contact with the stopper portion 6h or the back plate portion. The movement can be restricted by 8f contacting the rear wall portion 6b of the housing 6. In this way, it is possible to make it difficult for the shell 8 to be displaced relative to the housing 6.

  Further, if the housing 6 does not have such an attachment recess 6f and the housing fixing portion 8b1 is provided outside the housing 6, the entire connector 1 is increased in size by the housing fixing portion 8b1. In particular, when the housing fixing portion 8b1 protrudes below the housing 6 and is disposed so as to be inserted between the housing 6 and the substrate 2, the entire connector 1 is increased in height by the height of the housing fixing portion 8b1. . Therefore, the mounting recess 6f is provided on the lower end side of the side wall portion 6c of the housing 6 as in the present embodiment, and the housing fixing portion 8b1 is disposed in the mounting recess 6f, thereby increasing the size and height as described above. Can be suppressed.

[Explanation of usage]
Next, a method for using the connector 1 will be described. The flat conductor 3 described in the present embodiment is an FPC, and the connector 1 is electrically connected to the circuit of the substrate 2. As the FPC as the flat conductor 3, one having the latch receiving portions 3a on both ends in the width direction X is used. The latch receiving portion 3a shown in the present embodiment is formed as a notched portion in which the side surface of the FPC is notched in a concave shape, but may have a shape that an elastic lock piece 7 to be described later can be latched and prevented from coming off. For example, it may be a hole or another shape.

  First, as shown in FIG. 8, the flat conductor 3 is inserted into the connector 1 from the insertion port 9. As described above, the outer edge portion 8d of the shell 8 is formed so as to be shifted from the position on the extension line of the wall surface 6a1 of the front wall portion 6a toward the back side in the insertion direction of the flat conductor 3, thereby The opening width on the insertion port 9 side in the insertion direction of the conductor 3 is greatly enlarged. Therefore, since the operator can visually confirm the insertion port 9 from the upper surface side of the shell 8, the flat conductor 3 can be inserted into the connector 1 without searching for the insertion port 9 by hand. Further, at that time, the flat conductor 3 can be easily inserted into the connector 1 by inserting the tip of the flat conductor 3 obliquely from above the insertion opening 9 so as to be inserted into the insertion opening 9 obliquely (see FIG. 9). Since the step 6d of the housing 6 can be used as an insertion guide for the flat conductor 3 to be inserted obliquely when inserted into the insertion port 9, the flat conductor 3 is smoothly inserted into the connector 1. In this way, by allowing the flat conductor 3 to be inserted from obliquely above the connector 1, for example, even if another electronic component 13 is mounted near the insertion port 9 of the connector 1, the flat conductor 3 can be inserted. It can be easily inserted into the connector 1 and electrically connected.

  The tip of the flat conductor 3 inserted into the connector 1 through the insertion port 9 contacts the inclined portion 10d3 of the terminal 10 of the first terminal group 5a, and pushes down the terminal 10 toward the substrate 2 side. Over the contact portion 10d1. The tip of the inclined portion 10d3 of the terminal 10 and the engaging portion 7d of the elastic lock piece 7 are provided at substantially the same position in the height direction Z as the elastic piece portion 10c of the terminal 10 and the elastic piece portion 7c of the elastic lock piece 7, respectively. It is disposed at a lower position on the substrate 2 side than the upper surface of the step portion 6d of the front wall portion 6a. For this reason, immediately after the tip of the flat conductor 3 enters the fitting chamber 6g from the insertion port 9, it is caught by the tip of the inclined part 10d3 of the terminal 10 or the engaging part 7d of the elastic lock piece 7, or cannot be inserted. It is possible to prevent the terminal 10 and the elastic lock piece 7 from being buckled or damaged by being pushed in forcibly.

The flat conductor 3 is inserted into the back of the connector 1 along the back surface 8e of the upper surface portion 8a of the shell 8 while being pressed by the terminals 10 of the first terminal group 5a (FIG. 10). Then, the tip of the flat conductor 3 comes into contact with the inclined portions 7d3 of the two elastic lock pieces 7 almost simultaneously, and pushes the locking portion 7d toward the board 2 to get over. At that time, the tip of the engaging portion 7d of the elastic lock piece 7 enters the through hole 7c4 provided in the first extending portion 7c1. Therefore, the elastic lock piece 7 can be elastically deformed without being interfered by the first extending portion 7c1.
In addition, the rear wall 6b side of the step portion 7c5 in the first extension portion 7c1 is provided farther from the second extension portion 7c3 than the front wall portion 6a side. By doing so, even if the elastic lock piece 7 is pressed toward the substrate 2 by the flat conductor 3, the second extending portion 7c3 can be elastically deformed without being interfered with the first extending portion 7c1.

  When the flat conductor 3 is further moved along the back surface 8e of the upper surface portion 8a of the shell 8 into the back side of the fitting chamber 6g while the elastic lock piece 7 is pushed down, the flat conductor 3 is in the second state. The contact portion 10d of the terminal 10 of the terminal group 5b is pushed down to get over the second contact portion 10d2 (FIG. 11).

  Thereafter, when the flat conductor 3 is further moved into the fitting chamber 6g, the locking receiving portion 3a of the flat conductor 3 reaches the locking portion 7d of the elastic lock piece 7. The elastic locking piece 7 which is elastically deformed so that the locking portion 7d falls down always has a restoring force to return to the shell 8 side. Therefore, in a state where the latch receiving portion 3a reaches the latching portion 7d of the elastic lock piece 7, the elastic lock piece 7 enters the latch receiving portion 3a and is restored to its original shape. At this time, the vertical piece 7d1 of the locking portion 7d of the elastic lock piece 7 is substantially parallel to the inner edge 3a1 of the locking receiving portion 3a and locks the connector 1 (FIG. 12). At this time, the tip of the flat conductor 3 may be in contact with the rear wall 6b on the rear side in the insertion direction of the housing 6, but a gap may be formed between the flat conductor 3 and the rear wall 6b.

  In this state, the flat conductor 3 is sandwiched between the first contact portion 10d1 in the first terminal group 5a, the second contact portion 10d2 in the second terminal group 5b, and the upper surface portion 8a of the shell 8, and is flat. The mold conductor 3 and the terminal portion 5 are electrically connected. The shell 8 is formed of a thin metal plate, and high rigidity can be obtained even if the plate thickness is thin. Therefore, the shell 8 can firmly hold the flat conductor 3 between the terminal portion 5 and can receive the pressing force by the terminal portion 5 so that the flat conductor 3 and the terminal portion 5 are surely brought into conductive contact. . Therefore, the connector 1 can realize a reliable conductive contact with the flat conductor 3 while being thin.

  Next, a method for extracting the flat conductor 3 from the connector 1 will be described. As described above, the shell 8 has the through hole 8a1 above the locking portion 7d of the elastic lock piece 7. From this through hole 8a1, for example, by inserting a tool or the like with a projection and pushing down the locking portion 7d, the locking lock of the locking portion 7d with respect to the locking receiving portion 3a of the flat conductor 3 is released. The flat conductor 3 can be pulled out from the connector 1. By doing so, it is easy to maintain the conductive connection between the flat conductor 3 and the terminal portion 5, and the flat conductor 3 can be easily pulled out when necessary.

[Description of connector action and effect]
Next, the operation and effect of the connector 1 of the present embodiment will be described in addition to the above.
As described above, the outer edge portion 8d of the shell 8 is formed so as to be shifted from the position on the extension line of the wall surface 6a1 of the front wall portion 6a toward the back side in the insertion direction of the flat conductor 3. Thereby, the distance from the outer edge part 8d of the shell 8 to the first contact part 10d1 and the second contact part 10d2 is shorter than the distance from the outer edge part of the step part 6d (the wall surface 6a1 of the front wall part 6a). Has been. By doing so, the insertion distance of the flat conductor 3 can be shortened. Therefore, the fitting work of the flat conductor 3 and the connector 1 can be made efficient.

  When a force in the removal direction is applied to the flat conductor 3 while the flat conductor 3 is locked to the connector 1, the vertical piece 7d1 of the elastic lock piece 7 comes into contact with the inner edge 3a1 of the latch receiving portion 3a and comes off. The contact state between the terminal portion 5 of the connector 1 and the flat conductor 3 is maintained. Therefore, since the flat conductor 3 can be locked to the connector 1 without providing another member such as an actuator or a slider, the connector 1 can be downsized in the height direction Z. Further, since the locking can be performed by only one operation of inserting the flat conductor 3 into the connector 1, the fitting operation is easy.

  As described above, the first extending portion 7c1 of the elastic lock piece 7 is provided with the step portion 7c5 that bends in a crank shape. If the lower end of the folded portion 7c2 is arranged at the same height position as the horizontal piece 7b2 of the fixed portion 7b without providing the stepped portion 7c5, the connector 1 is enlarged in the height direction Z as a whole. Therefore, by providing this stepped portion 7c5, the lower end of the folded portion 7c2 is lowered by one step from the horizontal piece portion 7b2. By carrying out like this, the connector 1 can be made low-profile.

As described above, the bent portion 7d2 in the engaging portion 7d of the elastic lock piece 7, the first contact portion 10d1 in the first terminal group 5a, and the second contact portion 10d2 in the second terminal group 5b are moved in the front-rear direction Y. Arranged at different positions. In this way, the structure is such that these are in contact with and overriding the flat conductor 3 in order, and when the flat conductor 3 is inserted into the connector 1, the resistance that the flat conductor 3 receives simultaneously from the terminal portion 5 and the elastic lock piece 7. Can be reduced. Therefore, the flat conductor 3 can be inserted into the connector 1 with a smaller force.
Further, as described above, the first contact portions 10d1 and the second contact portions 10d2 are alternately arranged along the width direction X. By doing so, the resistance received by the flat conductor 3 from the terminal portion 5 can be distributed along the width direction X, and at the same time, the resistance of the flat conductor 3 caused by receiving the resistance from all the terminals 10 can be prevented. It can be made difficult to occur.

  According to the connector 1 of the present embodiment, the flat conductor 3 can be prevented from coming off without increasing the number of work steps. By doing so, the fitting work between the flat conductor 3 and the connector 1 can be made efficient. Further, according to the connector 1 of the present embodiment, the flat conductor 3 can be locked to the connector 1 while being low in height, and can be reliably connected to the terminal portion 5. Therefore, connection reliability can be improved without separately providing parts having a thickness in the height direction Z such as an actuator and a slider. Furthermore, according to the connector 1 of this embodiment, the resistance which the flat conductor 3 receives simultaneously from the terminal part 5 and the elastic lock piece 7 can be reduced, and it can be fitted with the flat conductor 3 with a smaller force. Therefore, it is possible to suppress damage caused by applying a strong force to the miniaturized connector 1 and to facilitate the fitting operation.

Modification of the embodiment:
In the above embodiment, the FPC without the shield layer 11 is shown as the flat conductor 3, but an FPC or FFC having the shield layer 11 is used as the flat conductor 3, and the contact portion between the shell 8 and the shield layer 11 is used. 12 is provided, soldered to the substrate 2 and grounded, whereby the connector 1 with more effective EMI countermeasures can be obtained (FIG. 13).

  In the embodiment, the fixing method by insert molding is exemplified as the fixing method of the terminal portion 5 with respect to the housing 6, but a terminal hole may be provided in the housing 6 and fixed by press-fitting.

  In the embodiment, the example in which the shell 8 is provided with the substantially rectangular through hole 8a1 on the upper side of the engaging portion 7d of the elastic lock piece 7 is shown. On the other hand, as shown in FIG. 14, the position of the through hole 8 a 1 may be slightly shifted from the position directly above the locking portion 7 d and provided, for example, on the elastic piece portion 7 c side of the elastic lock piece 7. And when the latching | locking part 7d enters into the latching receiving part 3a of the flat conductor 3, it is set as the structure which contact | abuts to the shell 8 and generate | occur | produces a contact sound. By doing so, the operator can confirm that the flat conductor 3 is locked to the connector 1 by this contact sound. When releasing the lock of the elastic lock piece 7, the lock is released by pushing down the elastic piece portion 7c of the elastic lock piece 7 to the substrate 2 side through the through hole 8a1, and the lock portion 7d is released from the lock receiving portion 3a. It is possible to remove the flat conductor 3 from the connector 1.

  As shown in FIG. 15, when the through hole 8 a 1 provided in the shell 8 is eliminated and the engaging portion 7 d of the elastic lock piece 7 enters the engaging receiving portion 3 a of the flat conductor 3, the shell 8 comes into contact. A structure that generates a contact sound can also be used. In this case, unlocking may not be possible, or the holding force by the elastic lock piece 7 may be adjusted softly so that the flat conductor 3 can be pulled out with a predetermined pulling force if the flat conductor 3 is pulled in the pulling direction from the connector 1.

  In the said embodiment, the operator pushed the flat conductor 3 in the connector 1, and showed the example which fits these. On the other hand, after the operator inserts the flat conductor 3 into the connector 1 and the engaging portion 7d of the elastic locking piece 7 contacts the inner edge 3a1 of the engaging receiving portion 3a, the insertion force is not applied. It is also possible to release your hands. In this case, the vertical piece 7d1 of the locking portion 7d can push the inner edge 3a1 toward the back in the insertion direction of the flat conductor 3 by the restoring force of the elastic lock piece 7. Thereby, even if an operator does not apply force, the flat conductor 3 can be automatically sucked into the connector 1 and stopped at a predetermined position.

  In the present embodiment, the second contact portion 10d2 is located at a position where the tip of the flat conductor 3 reaches at the same time that the locking receiving portion 3a of the flat conductor 3 reaches the locking portion 7d of the elastic lock piece 7. An example of placing is shown. In this case, the second contact portion 10d2 can be passed over the flat conductor 3, and the latch receiving portion 3a can reach the latch portion 7d of the elastic lock piece 7 as it is (FIG. 11). However, for example, when the latch receiving portion 3 a of the flat conductor 3 reaches the latch portion 7 d of the elastic lock piece 7, the depth in the insertion direction of the flat conductor 3 into the connector 1 is more than the tip of the flat conductor 3. It is good also as what arrange | positions the 2nd contact part 10d2 so that it may be located in the side. In this case, the latch contact portion 3a of the flat conductor 3 reaches the latch portion 7d of the elastic lock piece 7, and then the flat conductor 3 enters the back side of the connector 1 so that the second contact portion 10d2 is reached. Can be overcome. By doing so, it is possible to adopt a configuration in which the flat conductor 3 can be pushed into the back side by the restoring force of the elastic lock piece 7 to get over the second contact portion 10d2. Therefore, the operator can insert the flat conductor 3 into the connector 1 with a light force.

  Further, for example, contrary to the above, when the latch receiving portion 3 a of the flat conductor 3 reaches the latch portion 7 d of the elastic lock piece 7, the flat conductor to the connector 1 rather than the tip of the flat conductor 3. The second contact portion 10d2 may be arranged so as to be positioned on the near side in the insertion direction of 3. In this case, the locking portion 7d of the elastic lock piece 7 can enter the locking receiving portion 3a of the flat conductor 3 after the flat conductor 3 has completely passed over the second contact portion 10d2. By doing so, the operator can get over the second contact portion 10d2 before the engaging portion 7d of the elastic lock piece 7 enters the engaging receiving portion 3a of the flat conductor 3, and the fitting Can be confirmed with a sense of hand. Therefore, it is possible to make incomplete fitting difficult to occur.

  In the above embodiment, the example in which the flat conductor 3 is obliquely inserted into the insertion port 9 of the connector 1 has been described. However, the flat conductor 3 is inserted in parallel with the substrate 2 in accordance with the mounting state of the surrounding electronic component 13. Also good. The step portion 6d can function as an insertion guide, but whether or not to use the step portion 6d is arbitrary by the operator.

  In the above embodiment, the elastic lock piece 7 is formed of a metal piece, and the elastic lock piece 7 that does not buckle or buckle even when receiving a reaction force from the flat conductor 3 at the time of insertion is illustrated. (It is the same as FIG. 7 in the drawing). In this case, for example, it can be formed as a molded body integral with the housing 6, and according to this, there is an advantage that the number of parts of the elastic lock piece 7 can be reduced.
