Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION This invention relates to devices such as connectors, printed circuits, coil bodies, transformers, etc.
Or, it generally relates to a system for fitting a pin into any device that can accommodate the pin. In the example described below, the purpose of the system, though not limiting, is to fit the pins into holes in the connector.

[0002]

BACKGROUND OF THE INVENTION The term "pin" includes any type of male or female electrical contact that fits into a support or socket, and after these electrical contacts are inserted into the support, a complete electrical connector is formed. Or fixed to the device,
The cable can be terminated.

[0003] Before being fitted, the fitting pins, which technicians generally refer to as "studs", are:
It is fixed in a hole or cavity in the socket in the following manner. That is, such a method involves placing the pin in a hole in a mold and overmolding the pin with a suitable plastic that will constitute the socket of the connector to be obtained.
g) or force the pin into a pre-formed hole in a plastic socket.

[0004] Whichever method is used, a quick fit of the pin is required in each case, depending on the packaging of the pin. This is because the pins are loose, are provided on a transport strip, or are provided in the form of pre-cut sections of continuous wire wound on a reel.

[0005] The system according to the invention relates essentially to a pin formed by a separable part of a continuous wire wound on a reel, in other words the separable parts are arranged side by side, They are connected to each other by weak areas of small cross-section forming a "notch".

[0006] Pin-fitting systems based on separable portions of a continuous wire exiting a reel are already disclosed in US Patent Nos. 4,176,448 and 4,318,96.
No. 4 is taught.

With this system, the separable portion of the continuous wire is paid out one by one, then the first end portion is separated from the rest of the continuous wire, and this separated portion is finally inserted into a hole in the connector support. It becomes possible to do. Although widely used, this system has the following disadvantages:

[0008]

Such prior art systems include a punch-type cutting mechanism for separating the first end portion from the rest of the continuous wire, the cutting mechanism being drawing. This acts on the fragile region in a direction orthogonal to the axis of the end portion. Since the continuous wire forming the pin is formed of a soft conductive material (brass, bronze, or the like), the fragile region does not break cleanly, so that burrs remain at the ends of the pin. This is a very important point, and due to the tolerance of the length of the separable part forming the future pin, the notch defining the fragile area can be optimally positioned relative to the punch of the cutting mechanism. Because it is difficult. Thus, such burrs can interfere with the actual connection operation and cause a subsequent failure.

Further, another disadvantage of this conventional system is that
Near the end to be separated from the rest of the continuous wire,
Due to the arrangement in which the punch-type cutting mechanism is located, there is a bulky mechanical device near the insertion gripper, and several pins, especially between two adjacent pins, are currently needed. It is impossible to simultaneously fit the pins at a pitch of less than 2 mm. Further, a connector having a plurality of rows of right-angle pins, and firstly inserting a linear pin that becomes shorter for each row, and then fitting the right-angle pins in the next operation, Cannot be handled by the system described in the patent.

[0010] Such conventional systems also have other disadvantages. In particular, it is relatively slow because only one pin is inserted at a time. Also, the use of a retractable punch-type cutting mechanism is noisy and generates periodic shocks and vibrations, which always adversely affect the actual system and its adjustment, and also cause the end parts to be separated during the separation operation. The metal particles generated by the punch-type cutting mechanism accumulate. Also,
Punches must be changed regularly.

It is an object of the present invention to overcome these drawbacks, in particular with the ability to separate the ends without burrs and without strict alignment in the fragile area. Several pins with different lengths and cross-sectional areas
The present invention relates to a system that can be fitted simultaneously with any fit shape (eg, four aligned, four forming a square vertex and one in the middle).

[0012]

SUMMARY OF THE INVENTION To this end, a system for fitting a pin formed by a portion of a continuous wire that is connected sequentially at a fragile area and separable at the fragile area, especially to a device such as a connector, is known. According to the invention, an advance / guide unit for stepwise advancement and guidance of the continuous wire and a fitting unit for fitting a part of the continuous wire into the device, these units being movable with respect to each other At the end of the continuous wire
From the loading position, which is the first position introduced into the fitting unit by the guide unit, to the fitting position, which is the second position where the end portion of the continuous wire separated from the rest of the continuous wire can be fitted into the device. Alternatively, the two units move relative to each other from the second position to break the corresponding weakened area, thereby separating the end portion from the rest of the continuous wire.

[0013] Due to the construction of the system with respect to the advance / guide unit and the fitting unit which can move relative to each other, the separation of the end portion from the rest of the continuous wire is a simple relative operation between the two units. This is performed by breaking the fragile area by the movement, which is performed without relying on a cutting mechanism such as a punch mechanism.
As a result, high operational reliability of the system according to the invention is ensured, since there is no burrs, no noise and no vibration, and the maintenance required for the system is reduced. Furthermore, the absence of a cutting mechanism near the part to be separated allows the space around the two units to be free, so that pins arranged at small pitches ( The separation part) can be fitted simultaneously with several pins having different lengths and cross-sectional areas.

Preferably, in the first position, the advance / guide unit and the fitting unit are aligned so that the end portion introduced into the fitting unit and the remaining part of the continuous wire guided in the advance / guide unit are The insertion unit is orthogonal to the advance / guide unit in a second position after the relative movement between the two units, having a linear shape defining the direction of advance of the continuous wire and breaking the corresponding weakened area In position so that the end portions can be fitted into the device.

In particular, the relative movement between the advance / guide unit and the fitting unit is such that the fitting unit is rotated about an axis perpendicular to the direction of advance of the continuous wire so that the fitting unit is aligned with the forward / guide unit. Moving from the position to a second position in a direction orthogonal to the first position.

Structurally, the advance / guide and fit unit is supported by a frame, the fit unit being linked to the frame and mounted on a rotating shaft orthogonal to the direction of advance of the continuous wire, and driving means. Can move the fitting unit from the first position to the second position or vice versa.

Preferably, the advancing / guiding and linking units are linked together and move from the first position to the second position so that the advancing / guiding unit follows the fitting unit and provides a weakened area between the parts. Can be smoothly broken. As a result, it is possible to obtain a pin that is gradually and neatly separated, has a contour without irregularities, and is not deformed.

In the present embodiment, the link mechanism between the advance / guide unit and the fitting unit is provided with an end portion parallel to the rotation axis and housed in the fitting unit and a continuous wire housed in the advance / guide unit. Formed by a hinge pin facing the weakened area between the rest and the advance / guide unit being mounted for rotation about a pivot pin parallel to the hinge pin and carried by the slide; The slide can slide along the frame in a direction perpendicular to the pivots and hinge pins. Preferably, the pivot pin is
It is located at the rear of the advance / guide unit, opposite the hinge pin located at the front of the advance / guide unit. Thus, the advance / guide unit swings and slides like a piston rod of an internal combustion engine.

Further, the advance / guide unit includes at least one longitudinal guide channel for receiving the continuous wire and a controllable advance mechanism for interacting with the continuous wire to ensure that the continuous wire can be advanced stepwise. And Several longitudinal channels may be arranged parallel to each other, each containing a continuous wire. This allows some of the end portions to be separated and housed in the fitting unit and fitted into the socket of the connector. Of course, any number and arrangement of channels may be used as needed, without departing from the scope of the invention, for example, two, three, four or more channels may be arranged in a row, They can be arranged in a triangle, square or pentagon, etc., so that several pins (separated ends) can be fitted into the socket of the connector at the same time.

[0020] In a preferred embodiment, the fitting unit includes a support combined with the rotating shaft and a fitting head slidably mounted on the support, the fitting head being in the first position. Forward when in /
At the end facing the guide unit, there is at least one housing capable of receiving an end portion of the continuous wire. If the advance / guide unit is provided with a plurality of channels, each containing a continuous wire, the fitting head is provided with a plurality of corresponding housings.

[0021] The system further includes actuating means for sliding the setting head so that the end portion is securely introduced into the device when the setting unit assumes the second position.

Further, the operating means has a cam which is connected to a rotating shaft supporting the fitting unit via a synchronous mechanism and is driven to rotate, and when the fitting unit takes the second position, the cam is moved. The action causes the fitting head to slide toward the device so that the end portions can be fitted.

Further, the retaining means can ensure that the end portion is restrained within the housing in the fitting head until the end portion is fitted immediately after being separated from the rest of the continuous wire. Preferably, the holding means is
It is of the suction type and comprises a fluid supply which interacts with the housing via a duct formed in the fitting head.

Also, a spring-type return member is provided between the support of the fitting unit and the fitting head for returning the fitting head to the inoperative position after the end portion has been fitted.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings clearly illustrate how the invention may be realized. In these drawings,
The same reference numerals indicate the same members.

The purpose of the pin fitting system 1 shown in FIGS. 1 to 3 is to allow the pin B to be fitted or inserted into the hole of the connector C so that it can later interact with another connector having additional pins. It is to be. In order to supply the pin B to the pin fitting system 1, as shown in FIG. 4, the pin B is formed of the same part of the continuous wire F, and these parts form a “notch”. They are sequentially connected by a weak area Z having a low strength. The continuous wire F is fed out of the reel in a known manner, not shown, and is fed out in a stepwise manner by the pin fitting system 1 as will be described later, so that the end pin or end portion BE becomes the remaining portion of the continuous wire F. Separated from
The connector is inserted into the corresponding hole.

In the example shown, the pin-fitting system 1 accommodates four continuous wires arranged in parallel (in a horizontal row) and simultaneously fits four pins into the corresponding holes of the connector in each actuation cycle. Can be included. Of course, the number of continuous wires and their arrangement (arranged in a triangle, square, pentagon, etc.) could be varied as needed without departing from the scope of the invention.

A pin fitting system 1 according to the present invention
Includes a forward / guide unit 2 for progressively advancing and guiding the continuous wire F in the forward direction A, and a fitting unit 3 for fitting an end pin of the continuous wire F to the connector.

The two units 2 and 3 are supported by a frame 4 in the form of a plate and are mounted for relative movement with respect to each other to connect the end portions or end pins BE of four parallel continuous wires F. Forward / guide unit 2
The loading end position (FIGS. 1 to 3), which is the first position to be introduced into the fitting unit 3, is moved from the remaining portion of the four continuous wires F after the corresponding weakened region is broken by the relative movement. It is possible to reversibly set a fitted end position (FIGS. 9 and 10), which is a second position where the end pin BE of the separated continuous wire can be fitted into the corresponding hole of the connector C.

In the illustrated embodiment of the pin fitting system 1, the fitting unit 3 is linked to a frame 4 and mounted on a rotating shaft 5 perpendicular to the direction A of advance of the continuous wire. The rotating shaft 5 is connected to the frame 4
, And the plane of the frame 4 is arranged in a vertical plane in the drawing.
The geometric axis of the rotating shaft 5 is horizontal.

In particular, the fitting unit 3 has a support 7 combined with the rotary shaft 5 and a sliding surface 9 provided on the support 7 and arranged in a direction orthogonal to the geometric axis of the rotary shaft 5. And a fitting head 8 slidably mounted. The fitting head 8 has a tapered end 8A in which four parallel housings 10 are formed for receiving the end pins BE of the continuous wire F.
The other end 8B of the fitting head 8 has a fitting head 8
A wheel 11 is provided which can interact with actuating means 12 for sliding the pin with respect to the support 7 and thus allow the pins to be inserted into the connector C. Holding means 13 for holding the separated pins at a position in each housing 10 are provided;
The holding means 13 includes a fluid suction source (not shown) connected to the housing 10 via a duct 8C formed in the fitting head 8. Further, an elastic return member 14 such as a spring is provided between the support 7 and the fitting head 8.
A fitting head is provided parallel to the direction of sliding in the support.

The advance / guide unit 2 comprises a support 15 having four parallel longitudinal channels 16 in which a continuous wire F fed from a reel (not shown) is arranged. These four channels 16 can in each case be constituted by tubes or ducts or guide slots or grooves forming the channels 16 so as to be able to guide the matching part of the continuous wire F.

The synchronous stepwise advancement of the continuous wire in each working cycle of the pin-fitting system 1 is provided by an advancement mechanism 17 in the form of a runner or a pawl, which is shown symbolically in the drawing and, for example, By interacting with the weakened zone Z between two successive parts of each continuous wire, it can be advanced one step equal to the length of each part towards the fitting unit 3 (of course, a special In the case of fitting, each continuous wire or group of continuous wires could be advanced independently).

To do this, in the loading position, which is the first position, the forward / guide unit 2 and the fitting unit 3 are aligned, and the channel 16 in the forward / guide unit 2 and the housing 10 in the fitting unit 3 are So that each is on an extension of each other.

In particular, in FIG. 5, there is a certain separation between the opposed ends 8A and 15A of the two aligned units 2 and 3, guiding the end pins BE and the channels 16 located in the housing 10. The weakened zone Z between the second pin BP and the end of the pin is located in the space between the two units, and almost all of the pins BE and BP are confined in the housing of the respective unit and the corresponding channel. Need to be pointed out.

Also, the two units 2 and 3 are linked to each other so as to ensure the desired kinematic behavior of the pin fitting system 1. In this example, the link mechanism between the two units is constituted by a hinge pin 19 which is parallel to the rotation axis 5 and connects the two supports 7 and 15. Further, the hinge pin 19 is located at a position extending in a substantially orthogonal direction from the weak region Z between the end pin BE of the continuous wire F and the second pin BP from the end.

The forward / guide unit 2 is connected to the fitting unit 3 by the hinge pin 19 so that the forward / guide unit 2 can follow the rotation of the fitting unit 3.
The slide pin 21 is attached to the hinge pin 19 so as to rotate around a pivot pin 20 carried by a slide 21. The slide 21 is connected to the pivot pin 20 and the hinge pin 19 through a slide surface 22 integrated with the frame 4. It can slide in orthogonal sliding directions. The pivot pin 20 is located at the rear end 15B of the forward / guide unit 2, and the front end 15A of the forward / guide unit 2 faces the fitting unit 3.

Thus, the advance / guide unit 2 can be compared to a connecting rod of an internal combustion engine, the crankshaft of which will be the fitting unit 3 and the piston will be the slide 21.

Actuating means 1 for sliding fitting head 8
2 is a cam 23 attached to a shaft 24 in the illustrated example.
The shaft 24 is supported by the frame 4 and is parallel to and vertically aligned with the rotation axis 5 of the fitting unit 3.
Since the shaft 24 of the cam 23 is mechanically connected to the rotary shaft 5 via a suitable synchronization mechanism 25, the action of the cam 23 on the fitting head 8 of the fitting unit 3 is such that the fitting head will be described later. This is only possible when taking the second position.

The operation of the pin fitting system 1 according to the present invention is performed as follows.

Initially, assume that the pin-fitting system 1 is in the loading end position, which is the first position shown in FIGS. 1, 2, 3 and 5 corresponding to the start of a working cycle. In this first position, the two units 2 and 3 are horizontally aligned and the housing 10 in the setting head 8 has a channel 16 for guiding a continuous wire F.
It is on an extension of. The end pin BE of the continuous wire F is advanced by the advancement mechanism 17 into the housing 10 in the fitting head 8 in the inoperative position with respect to the support 7 by the action of the return spring 14. At this time, the four vulnerable areas Z
Are located between the two units 2 and 3 and are substantially aligned with the hinge pins 19 of these two units.

At this time, the driving motor 6 rotates the fitting unit 3 in the direction of the arrow R by the rotating shaft 5 and moves it from the horizontal position to the vertical position. FIGS. 6, 7 and 8 show the intermediate position of the fitting unit 3 in which the forward / guide unit 2 is swung and slid together by the hinge pin 19 like a connecting rod of an internal combustion engine. The front part of the advance / guide unit 2 advances along the rotation path described by the hinge pin 19, while the rear part of the advance / guide unit 2 rotates around the pivot pin 20 while sliding on the sliding surface 22-slide. 21 Follow a straight path along the junction. During this movement, the housing 1 of the fitting unit 3
0 and the remaining portion of the continuous wire F located in the channel 16 of the advance / guide unit 2 gradually bend in the weak zone Z, changing from the aligned state to the bent state. 6, 7 and 8, the fragile region Z is
It starts to break gradually.

When the rotation R of the fitting unit 3 is continued and the fragile area Z of each end pin BE breaks from the remaining part of the continuous wire F, the fitting unit 3 takes the second position, in this case, as shown in FIG. 9, as shown in FIGS. 10 and 11, it is rotated by an effective 90 degrees and is in the vertical position.

Due to the link mechanism between the two units 2 and 3 and the resulting rotation and swinging movement, the breakage of the fragile zone Z leading to the separation of the two successive pins BE and BP occurs gradually and finely, No deformation or deformation of the pin.

Until the fitting unit 3 reaches the second position, the holding means 13 (see FIG. 11) operates and the duct 8
Each separation pin is restrained in the respective housing 10 by suction by C while being pressed against the bottom 10A thereof. Thus, when the fitting unit 3 takes the second position, the end pin BE is held in the housing 10.

When the fitting unit 3 moves from the first position to the second position, the shaft 24 carrying the cam 23 rotates via the synchronization mechanism 25, and the support 7 for the fitting unit 3 moves to the second position. 9 and FIG.
), Only the cam 23 comes into contact with the wheel 11 of the fitting head 8.

Further, the cycle of the pin insertion system 1 continues, and the two units 2 and 3 are restrained at predetermined positions by stopping the drive motor 6, while the contour 23A of the cam 23 drives the insertion head 8 by "driving". (Attac
k) "and the fitting head 8 slides relative to the support 7 towards the connector C, which is symbolized in FIGS. In order not to obstruct the sliding of the fitting head 8 in the vertical downward direction, the advance / guide unit 2 is returned to a position slightly away from the return means (not shown), or the fitting is performed as soon as the end part is separated. The “follow-up” to the unit 3 is performed by, for example,
The operation is terminated by elastic stop means (not shown) disposed between the guide unit 2 and the guide unit 2. Of course, the connector C is positioned so that its housing hole faces the pin BE to be fitted. While the setting head 8 moves down from the inactive position to the active position, the resilient return spring 14 is compressed by the action of the profile 23A of the cam 23 until the end pins BE are completely mounted, so that each end pin BE is fully mounted. Are fitted in corresponding holes in the connector C. Of course, the holding means 13 for holding the pin BE has been deactivated in advance. In the position shown in FIG. 12, the eccentric distance E of the cam 23 from the geometric axis of the shaft 24 is at a maximum and the setting head 8 is in the lower operating position and compresses the elastic return spring 14. ing.

Next, as the cam 23 continues to rotate, its eccentric distance E decreases, and by the action of the relaxed elastic return spring 14, the fitting head 8 returns to the inoperative position above it (FIGS. 14 and 15). reference). Outline 23A of cam 23
At this time, the fitting head 8 at the upper position in the vertical direction is
And the unit 2 and 3 are returned to the positions shown in FIGS. 1 and 3 by re-actuating the drive motor 6 of the rotating shaft 5 in the opposite direction. The operation cycle of the pin fitting system 1 is completed.

The advantages of the pin-fitting system according to the invention can be summarized as follows: the separation by gradually bending at the weakened area does not involve lateral forces and therefore does not result in the formation of burrs As a result, a complete decoupling of the end portions takes place, without having to very precisely position the center of the weakened area on the axis of rotation in order to separate the end portions, which end portions are located within the housing in the fitting head. Because they are free, fully automatically and individually aligned along the axis of rotation, and lack a specific cutting mechanism, they can supply end parts that are placed very short distance apart, possibly long Nothing prevents simultaneous fitting of several end sections of different height and cross-section, which is very useful for connectors with right-angled outputs Yes, all of these criteria allow higher production speeds to be achieved than with the conventional pin-fitting systems described above, while improving the quality of the pin ends and cutting members within the pin-fitting system. The absence has the further advantage that maintenance is reduced because there is no cutting debris, there is no punch to change, there is no impact on the end parts when cutting, and thus the mechanism is completely silent.
