BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a terminal press-fitting device for which a tip end section of a terminal provided in a projected manner in a connector housing is press-fitted into an insertion hole formed on a substrate to connect the terminal and the substrate.

2. Description of the Related Art

A conventional structure is described in JP-A-7-65929, for example. In JP-A-7-65929, a for-substrate connector in which pin-like terminals (for-substrate connection pieces) are provided in a matrix form and are provided in a projected manner is mounted on a substrate such that the first comb teeth-like terminal arrangement plate in which guide grooves for guiding the pin-like terminals arranged in columns are formed at the same interval as the column space pitch and the number of columns is attached at a position in the vicinity of a face of the connector abutting against the substrate. Thereafter, the second comb teeth-like terminal arrangement plate in which guide grooves for guiding the terminals arranged in rows are formed at the same interval with the row space pitch and the number of rows is attached in the vicinity of the surface of the above-mentioned first comb teeth-like terminal arrangement plate. Then, the tip end of the above-mentioned terminal projecting out of the surface of the second comb teeth-like terminal arrangement plate and the insertion hole (through hole) of the substrate are used to temporarily mount the connector on the substrate to remove the first and the second comb teeth-like terminal arrangement plates. Thereafter, the above-mentioned connector is pressed toward the substrate side so that this connector is mounted on the substrate.

As described above, the above-mentioned structure is provided such that the above-mentioned tip end section of the terminal is press-fitted into the insertion hole formed in the substrate while the pin-like terminals provided in a projected manner in the connector housing are restricted by the above-mentioned first and the second comb teeth-like terminal arrangement plates. This structure has an advantage in that the above-mentioned connector can be mounted on the substrate without requiring special man-hours for modification even when these terminals have a thin shape and thus tend to be bent or to slant. However, this structure has a problem in that arrangements other than the matrix-like arrangement in which a plurality of terminals are provided on intersection points at which a plurality of lines extending column-wise of the connector and a plurality of lines extending row-wise intersect with one another prevent the comb teeth of the first and the second comb teeth-like terminal arrangement plates from providing the function for sufficiently positioning the terminals, thus failing to provide an effective prevention in the deformation of the terminals.

Specifically, this structure has a problem as shown below. When the terminals of the connector are arranged in a staggered manner due to a layout reason any of the comb teeth of the first comb teeth-like terminal arrangement plate and the comb teeth of the second comb teeth-like terminal arrangement plate cannot be straightly introduced to the area in which the above-mentioned terminals are provided As a result, when the above-mentioned tip end section of the terminal is press-fitted into the insertion hole of the substrate, the terminal cannot be positioned precisely, making it difficult to press-fit the tip end section of the terminal into the insertion hole of the substrate properly. In the case of a so-called press fit connector, in particular, by which the terminals and the substrate can be connected only by press-fitting the terminal into the insertion hole of the substrate without requiring soldering, when press-fitting the terminal into the above-mentioned insertion hole, an extremely large press-fitting force is required. Thus, an insufficiently-positioned terminal causes deformation of the terminal such as bending and slanting.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a terminal press-fitting device by which, even when at least some of the terminals provided in a projected manner in a connector housing are arranged in a staggered manner, the terminals can be press-fitted into the insertion holes of the substrate in an appropriate manner while each of the terminals is being appropriately restricted.

In order to solve the above-mentioned problem, the present invention provides a terminal press-fitting device in which a plurality of terminals are provided in a connector housing in a projected manner, and terminals of a connector having a staggered,arrangement section of the terminals for which an arrangement position of the terminals in a lateral direction of the connector housing is set in a staggered manner are press-fitted into an insertion hole formed on the substrate, comprising: a first terminal restricting member on which a guide section for restricting the vertical displacement thereof by being introduced between the terminals along the lateral direction of the connector housing is provided; and a second terminal restricting member on which a guide section for restricting the lateral displacement thereof by being introduced between the terminals along the vertical direction of the connector housing in an upper or lower part of the first terminal restricting member is provided; wherein guide grooves to which terminals arranged on the interior side of the connector housing are introduced is provided at a tip end portion of the guide portion of the first terminal restricting member positioned at the staggered arrangement section of the terminals.

According to the above-mentioned structure, in accordance with an operation for introducing the guide section of the first terminal restricting member between the terminals arranged at the exterior side of the above-mentioned staggered arrangement section, the terminals arranged at the interior side are introduced into the above-mentioned guide grooves, thereby restricting the vertical displacement of each terminal by the base end section and the tip end section of the above-mentioned guide section, respectively. The guide section of the above-mentioned second terminal restricting member in this state is introduced along the vertical direction of the connector housing to a part in which the terminal is provided, thereby restricting the horizontal displacement of each terminal by the guide sections of the above-mentioned first and second terminal restricting members.

It is preferable to have a structure in that the lower end face of an expanded section provided at each terminal is provided to be opposed to the upper end face of the guide section composing the first terminal restricting member, and when the terminal is press-fitted, the lower face of the expanded section is made to abut against the upper end face of the guide section so as to restrict the displacement of each terminal in the lower direction.

According to the above-mentioned structure, when the tip end section of the terminal is press-fitted into the insertion hole of the substrate, the lower face of the above-mentioned expanded section abuts against the upper end face of the above-mentioned guide section to restrict the displacement of each terminal in the lower direction, thereby effectively preventing buckling deformation of the terminal.

This terminal press-fitting device includes: the support table7for supporting the above-mentioned connector housing2and the substrate6while they are positioned; the base plate9for allowing the above-mentioned support table7to be slidably supported in the front and rear directions along the pair of left and right guide rails8provided at the upper face; the pair of left and right elevation bars10provided at the depth side of this base plate9; the pressing plate11that is supported to be elevated along this elevation bar10; and the elevation driving mechanism13including the operation handle12for pushing down this pressing plate11by a manual operation. It is also possible that the above-mentioned elevation driving mechanism13has an electric driving section, an air pressure driving section, or a hydraulic driving section to automatically move the above-mentioned pressing plate11up and down in accordance with the switch operation.

The above-mentioned support table7has: the placement plate7aon which the connector housing2is placed; the positioning stopper14to which the side end face of the connector housing2placed on this placement plate7ais pushed so that the connector housing2is positioned in the lateral direction Y; the first terminal restricting member15provided at the depth side of the above-mentioned placement plate7a;the second terminal restricting member16that is slidably provided in left and right directions at one side of the support table7; the clamp member17making pressure contact with the rear face section of the above-mentioned connector housing2; and the connector-holding mechanism18for pushing this clamp member17toward the depth side of the support table7to hold the connector housing2.

The support table7also has formed a pair of left and right positioning holes19. When the terminal3described later is press-fitted, a positioning pin (not shown) provided in the elevation driving mechanism13is inserted into the above-mentioned positioning hole19, thus positioning the above-mentioned pressing plate11and the support table7. At the depth side of the above-mentioned support table7, there is also provided the substrate-holding section20for holding the positioned substrate6. At the front end of the support table7, the grip21for sliding operations is attached.

As shown inFIG. 7andFIG. 8, the above-mentioned first terminal restricting member15has a plurality of guide sections22that are arranged in the vertical direction X of the connector housing2at a fixed interval and that are provided in a projected manner in the lateral direction Y of the connector housing2. Each guide section22consists of a plate member having a thickness that can be introduced into the terminals3adjacent to one another that are arranged in the above-mentioned vertical direction X and is provided at a position at which the upper end face is opposed to the lower end face of the expanded section3bprovided in each terminal3.

The guide section22of the above-mentioned first terminal restricting member15is structured to, in accordance with an operation for holding the connector housing2described later, be introduced along the lateral direction Y to a region in which the terminals3are provided. As a result, when a erecting section of each terminal3(lower part of the expanded section3b) abuts against the above-mentioned guide section22, the displacement of each terminal3in the vertical direction X is restricted and, when the tip end section of the terminal3is press-fitted into the insertion hole6aof the substrate6, the expanded section3bof each terminal3abuts against the upper face of the above-mentioned guide section22, thus restricting the displacement of each terminal3in the lower direction. Furthermore, the above-mentioned guide section22has a tapered shaped taper face22athat functions as a guide face for introducing the tip end section between the terminals3.

Among the guide sections22positioned in the staggered arrangement section5of the above-mentioned terminals3A and3B, the guide section22that is introduced between the terminals3A arranged on the front face of the connector housing2has, at the front end thereof, the guide groove23having a predetermined width that extends in the upper and lower directions. The interior of this guide groove23is introduced with the erecting section of terminal3B arranged at the rear side of the above-mentioned terminal3A (lower part of the expanded section3b).

As shown inFIG. 9andFIG. 10, the above-mentioned second terminal restricting member16extends along the vertical direction X of the connector housing2and consists of comb teeth-like plate members that are provided in the lateral direction Y of the connector housing2at a fixed interval and that have a plurality of guide sections25. The second terminal restricting member16is supported so as to be slidable in the vertical direction X of the above-mentioned connector housing2by the support mechanism24provided at one side of the above-mentioned support table7. The guide section25of the above-mentioned second terminal restricting, member16is introduced along the upper face of the above-mentioned first terminal restricting member15and the vertical direction X of the connector housing2to the region in which the terminals3are provided. As a result, the guide section25abuts against a part in the vicinity of the tip end section of each terminal3, that is, a part corresponding to the press-fitting section3aof each terminal3, to restrict the displacement of each terminal3in the lateral direction Y.

The support mechanism24of the above-mentioned second terminal restricting member16has: the support bracket26provided at one side of the support table7; a pair of upper and lower guide bars27that are provided in a projected manner and that are horizontally provided toward the exterior side from this support bracket26; and the slide block28that is slidably supported along this guide bar27. The upper face of this slide block28is attached with the base end section of the above-mentioned second terminal restricting member16. When the above-mentioned slide block28is slid to have a horizontal displacement along the guide bar27, the above-mentioned second terminal restricting member16is moved from a stand-by position as shown inFIG. 9in which the second terminal restricting member16evacuates to the exterior side of the support table7to a restrictive position as shown inFIG. 10in which the above-mentioned guide section25restricts the lateral displacement of the terminal3(seeFIG. 13).

As shown inFIG. 11, the above-mentioned connector-holding mechanism18has the driving shaft29that is, provided in a projected manner at the clamp member17; the support cylinder30for supporting this driving shaft29in a slidable manner; and the operation lever31for allowing the above-mentioned driving shaft29to move into or to move out of the support cylinder30so that the clamp member17is moved in the front and rear directions. By making the above-mentioned operation lever31operate to push the driving shaft29toward the front side while the connector housing2is being provided on the above-mentioned placement plate7aand its side end section is made to abut against the positioning stopper14to be positioned in the left and right directions, the rear face of the above-mentioned connector housing2is engaged with the clamp member17in a press contact manner.

By making the connector housing2be pushed via the above-mentioned clamp member17toward the depth side of the support table7, each guide section22of the first terminal restricting member15is introduced along the lateral direction Y of the connector housing2to the region in which the terminals3are provided as shown inFIG. 8and the above-mentioned connector housing2is held to be positioned on the substantial center part of the support table7as shown inFIG. 11.

As shown inFIG. 11andFIG. 12, the above-mentioned substrate-holding section20has; a pair of left and right supporting columns33that are supported in an elevatable manner by the slide support section32provided at the inner end section of the support table7; the elevation frames34provided between the upper end sections of these supporting columns33; a pair of left and right arms35that are provided in a projected manner in this elevation frame34; and a pair of left and right positioning pins36fixed to the above-mentioned elevation frame34. The above-mentioned substrate-holding section20is structured such that, when the substrate6is held by the above-mentioned substrate-holding section20, this positioning pin36is inserted into the positioning hole6aof the substrate6to position the substrate6on the support table7in the horizontal direction.

The above-mentioned supporting column33is externally engaged with the compression coil spring37for biasing the elevation frame34in an upward direction and, at the lower face side of the support table7, the lock plate38having the magnet39is fixed to the lower end of the supporting column33. In a normal setting, the above-mentioned elevation frame34and the positioning pin36are locked to the substrate set position in the upward direction as shown inFIG. 12Aby the biasing force of the above-mentioned compression coil spring37. In a press-fitting operation which will be described later, the above-mentioned supporting column33and the lock plate38are lowered in accordance with a pushing down force from the above-mentioned pressing plate11against the biasing force by the above-mentioned compression coil spring37. As a result, the holding plate40consisting of magnetic material that is provided in the lower direction of the support table7attracts the above-mentioned magnet plate39, thus holding the above-mentioned elevation frame34and positioning pin36at the lowering position shown inFIG. 12B.

In order to connect the substrate6to the connector1by using the press-fitting device structured as described above to press-fit the tip end section of the terminal3to the insertion hole6aof the substrate6, the connector housing2is first made placed on the placement plate7aof the support table7as shown inFIG. 11, and held in a manner such that the connector housing2is positioned at the approximately center portion on the support table7by operating the connector holding mechanism18to press-contact the clamp member17to the rear face of the connector housing2in a state where the one end part of the connector housing2is made to abut against the positioning stopper14.

In accordance with this operation for holding the connector housing2, the matrix-like arrangement section4of the terminals3is provided such that the guide section22of the first terminal restricting member15is introduced to the rear side along the lateral direction Y of the connector housing2and the above-mentioned guide section22restricts the vertical displacement of each terminal3. On the other hand, the staggered arrangement section5of the terminals3A and3B are provided as shown inFIG. 8in which each guide section22of the first terminal restricting member15is introduced to the rear side along the terminal3A positioned at the front side of the connector housing2and, in accordance with this, the guide groove23formed at the tip end section of the guide section22is introduced with the terminal3B positioned at the rear side of the connector housing2. As a result, the above-mentioned guide section22and guide groove23restrict the vertical displacement of the terminals3A and3B, respectively.

Next, when the second terminal restricting member16at the evacuating position as shown inFIG. 9is slid to have a displacement toward the center of the support table7as shown inFIG. 13, then the guide section25of the second terminal restricting member16is introduced along the lateral direction Y of the connector housing2to a part in which the terminals3are provided, thus restricting the lateral displacement of each terminal3by the above-mentioned guide section25(seeFIG. 10). In this way, the connector housing2is held on the support table7while the guide section22of the first terminal restricting member15and the guide section25of the second terminal restricting member16accurately position the terminals3in the connector housing2that are projected in the upward direction, respectively.

Then, the substrate6is positioned such that the positioning pin36provided in the above-mentioned substrate-holding section20is inserted into the positioning hole6bof the substrate6and a part in which the above-mentioned insertion hole6ais provided is provided on the holding section of the above-mentioned connector housing2as shown inFIG. 14. As a result, the substrate6is held by the substrate-holding section20while the tip end section of the terminal3projected in an upward direction in the connector housing2is positioned to be temporarily inserted into the above-mentioned insertion hole6a.

As described above, the slide block28is slid along the above-mentioned slide bar27to have a displacement toward the exterior side of the support table7while the connector1and the substrate6are being held on the support table6, thereby canceling the restriction of the terminal3by the above-mentioned second terminal restricting member16. The grip21provided at the above-mentioned support table7is held to slide the support table7along the guide rail8to have a displacement toward the depth side of the base plate9, thereby moving the above-mentioned support table7to the press-fitting position provided at the depth side of the base plate9, as shown inFIG. 15. The above-mentioned support table7is slid to have a displacement until the support table7abuts against the stopper41provided at the inner end of the above-mentioned base plate9(seeFIG. 5), thereby setting the support table7at the above-mentioned press-fitting position.

Then, the operation handle12of the above-mentioned elevation driving mechanism13is operated to push down the pressing plate11as shown inFIG. 16, thereby allowing this pressing plate11to be pressure contacted with the upper face of the above-mentioned substrate6to bias the substrate6in the lower direction. As a result, the press-fitting section3bprovided at the tip end section of the terminal3is press-fitted into the insertion hole6aof the substrate6. In accordance with this press-fitting operation, the above-mentioned substrate6is connected with the connector1and the above-mentioned elevation frame34, the supporting column33, and the lock plate38are lowered to cause the magnet plate3910to be adsorbed on the holding plate40. As a result the substrate6on the elevation frame34is held to be linked to the connector1(seeFIG. 12B).

When the above-mentioned press-fitting operation is completed, the biasing force or the like of the return spring provided in the elevation driving mechanism13is used to raise the pressing plate11in the upward direction to the stand by position and the above-mentioned support table7is slid so as to be pulled to the front. Then, the holding status of the connector housing2by the above-mentioned connector-holding mechanism18is canceled as shown inFIG. 17and the integrally-connected connector1and substrate6are removed from the support table7. Thereafter, the arm35is raised in the upward direction or a guide section (not shown) is made to abut against the above-mentioned arm35to raise the elevation frame34, the supporting column33, and the lock plate38, thereby canceling the state in which the elevation frame34is held by the above-mentioned magnet plate39. As a result, the above-mentioned elevation frame35is returned to the substrate set position in the upward direction by the biasing force by the compression coil spring37.

As described above, the terminal press-fitting device by which the tip end section of the terminal3provided in a projected manner in the connector housing2is press-fitted into the insertion hole6aformed in the substrate6includes: the first terminal restricting member15including the guide section22that is introduced along the lateral direction Y of the connector housing2between the terminals3to restrict the vertical displacement of each terminal3; and the second terminal restricting member16including the guide section25that is introduced along the vertical direction X of the connector housing2between the terminals3to restrict the lateral displacement of each terminal3at an upper part of the first terminal restricting member15. The tip end section of the guide section22of the first terminal restricting member15positioned at the staggered-arrangement section5of the above-mentioned terminals3A and3B has the guide groove23to which the terminal3B positioned at the depth side of the connector housing2is introduced. As a result, even when the guide member cannot be introduced in a straight manner along the terminals3A and3B provided in the above-mentioned staggered arrangement section5, the tip end section can be press-fitted into the insertion hole6aof the substrate6in an appropriate manner while the terminals3A and3B positioned at the above-mentioned staggered arrangement section5are accurately positioned.

Specifically, the tip end section of the guide section22of the first terminal restricting member15has the guide groove23having a predetermined width. As a result, in accordance with the introduction of the above-mentioned guide section22between the terminals3A arranged at the exterior side of the connector housing2as shown inFIG. 8, the terminals3B arranged at the rear side of the above-mentioned terminal3A can be introduced to the above-mentioned guide groove23. In this way, when the above-mentioned guide section22is introduced to the terminals3A at the exterior side and the terminals3B at the interior side are introduced to the above-mentioned guide groove23, the bending of the terminals3A and3B can be corrected and the displacement of the terminals3A and3B in the vertical direction X can be effectively restricted by the base end section and the tip end section of the guide section22, respectively.

In this way, the guide section22of the first terminal restricting member15is introduced along the lateral direction Y of the connector housing2to the region in which the terminals3are provided to restrict the vertical displacement of the respective terminals3and the guide section25of the second terminal restricting member16is introduced along the vertical direction X of the connector housing2to the region in which the terminals3are provided to restrict the vertical displacement of the respective terminals3. As a result, each terminal3can be accurately positioned while preventing an adverse effect in which the terminal3is inclined or bent, for example. This allows, even in the case of a press fit connector requiring a large press-fitting force, the above-mentioned insertion hole6aof the substrate6to be inserted with the tip end section of the terminal3easily and securely to properly connect the terminal, of the connector1to the substrate6without causing deformation of the above-mentioned terminal3such as bending.

In the above-mentioned embodiment, the lower end face of the expanded section3bprovided in each terminal3is provided to be opposed to the upper end face of the guide section22composing the above-mentioned first terminal restricting member15so that, when the terminal3is press-fitted, the lower face of the above-mentioned expanded section3babuts against the upper end face of the above-mentioned guide section22to restrict the displacement of each terminal3in the lower direction. However, the above-mentioned embodiment may be changed such that the above-mentioned first terminal restricting member15has a stepped section that is introduced to the lower part of the base end section3dof the terminal3provided in a projected manner in the connector housing2so that this stepped section restricts the displacement of the above-mentioned terminal3in the lower direction.

In the structure as described above in which the stepped section provided in the first terminal restricting member15is used to restrict the displacement of the terminal3in the lower direction, there is a tendency where, when the tip end section of the terminal3is press-fitted into the insertion hole6aof the substrate6, the terminal3suffers buckling deformation due to the pressing load on the erecting section of the terminal3. To prevent this, it is preferable that the lower end face of the expanded section3bprovided in the terminal3is provided to be opposed to the upper end face of the guide section22composing the first terminal restricting member15as shown inFIG. 8so that the lower face of the above-mentioned expanded section3bis made to abut against the upper end face of the guide section22to restrict the displacement of each, terminal3in the lower direction, thereby preventing the load that causes the buckling deformation of the terminal3from being applied to the above-mentioned erecting section.

The above-mentioned embodiment described the connector1having the staggered arrangement section5in which two columns of terminals3A and3B are arranged in the lateral direction Y of the connector housing2. However, the present invention also can be applied to a connector in which the groove depth of the guide groove23formed in the guide section22of the first terminal restricting member16(lateral length of the connector housing2) is set to have a value corresponding to the interval between the terminals3provided at two or more columns so that the lateral direction Y of the connector housing2has a staggered arrangement of three or more columns of terminals.

The terminal press-fitting device according to the present invention is also not limited to the connector1having the “L”-shaped terminal3that is formed by the base end section3dthat is provided in a projected manner and that is provided from the front face of the connector housing2in the forward direction; and the erecting section extending from the front end in the upward direction. The terminal press-fitting device according to the present invention also can be applied to a connector having a terminal that is provided in a projected and straight manner and, that is provided from the connector housing2in the upward direction. The terminal press-fitting device according to the present invention also can be applied to a connector in which all regions of the above-mentioned connector housing2have the staggered arrangement section5of the terminals.

The above-mentioned embodiment in which the guide section22of the first terminal restricting member15is constructed in the upward direction with the guide section25of the second terminal restricting member16also may be changed such that the guide section25of the second terminal restricting member16is provided in the upward direction with the guide section22of the first terminal restricting member15.
