BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector pin inserting head for a connector assembling machine for a printed circuit board.

[0002]

2. Description of the Related Art As a pin array inserting mechanism in a connector assembling machine for a printed circuit board, as shown in FIG.
The housing 3 of the connector into which the pin material 4 is inserted in the device A1 and the pin material 4 are continuously connected to the rail 6 and the rail 5 by the component aligning and supplying device (not shown). Supplied.

A pitch feed mechanism 36 including a housing feed pawl 12, a pin material feed pawl 13, a housing head detection pawl 16, and a lever 8 which form a pitch feed mechanism 36 facing the rails 5 and 6, and the pin. Cutter 9 for material 4
And a pin insertion claw 10 for inserting the pin material 4 into the housing 3.
And a pin insertion head 2a formed by the above, and each portion is driven by a cam driven by the same drive shaft (not shown) to insert the pins into a plurality of housings 3 at a predetermined pitch. A structure has been proposed in which the process is continuously performed.

Explaining an example in which two of the previously proposed pin inserting mechanisms are incorporated in a single-row assembly line, the lever 8 is swingable in the double arrow XX 'direction along the rails 5 and 6. The housing feed pawl 12 and the pin material feed pawl 13 which are arranged and attached to the lever 8 are
Only when the lever 8 moves straight in the direction of the arrow X, a predetermined feed is given to the housing 3 and the pin member 4, and the feed amount is 2P which is twice the pin arrangement interval P. .

If the two pin insertion mechanisms are A1 and A2, both feed the housing 3 and the pin material 4 with a feed amount of 2P, so the respective pin insertion phases are shifted by 1P, for example, the pin insertion mechanism A1 is an odd number. The pin at the second position is inserted, and the pin insertion mechanism A2 is operated to insert the pin at the even position.

The housing feed pawl 12 and the pin material feed pawl 13 perform the feeding operation by the forward and backward movement of the lever 8 by the same mechanism. The mechanism of the housing feed pawl 12 will be described with reference to FIG. As described above, the housing feed pawl 12 having the toe 23 engaged with the concave portion 24 on the lower surface of the housing 3 performs the feeding operation for a predetermined length by the movement of the lever 8 in the X direction. The non-cam flat portion 2 of the plate cam 18 that moves back and forth separately
7, the cam follower 19 of the housing feed pawl 12 is in contact, and when the feeding of the housing 3 of a predetermined length is completed, the cam portion 28 of the plate cam 18 comes into contact with the cam follower 19 and pushes down the housing feed pawl 12 toe 23 The recess 2
Remove from 4 and cut the feeding operation.

When the lever 8 is retracted in the direction of the arrow X ', due to the action of the beveled surface 12A of the tip of the housing feed pawl 12,
The claw 12 pivots downward with the fulcrum pin 17 as a swing point,
The feed claw 12 is returned to its original position by the tip of the toe slipping off the recess 24.

The pin material feeding claw 13 is operated in the same manner,
The feed hole 21 of the pin material 4 acts in exactly the same manner.

In addition to the pitch feed in the predetermined pin arrangement, for the feed corresponding to the connecting portion of the plurality of housings 3 which are continuously transferred, the housing leading end detection pawl 16 attached to the lever 8 has the end of the housing 3. The housing 3 is fitted in a groove 22 formed in the portion and is moved to a pin hole position of the next adjacent housing 3 by a predetermined feed amount or more.

Then, with a normal predetermined feed amount 2P,
The transfer of the both is sequentially performed on the rails 5 and 6. It should be noted that the lever 8 carries out an intermittent transfer in which the housing 3 and the pin member 4 are moved by a predetermined amount of 2P, and during the next transfer operation, both of them are returned to their original positions while being stopped at that position.

Therefore, at the time of stop, the pin material 4 is cut and the pin material 4 is inserted into the housing 3, and in a normal operation, the housing 3 and the pin material 4 have the same predetermined feed amount, Assuming that the pin interval is P, the pin 3 is transferred in parallel at the same timing with a feed amount of 2P, and the pin material 4 is cut and inserted uniformly when stopped, so that the housing 3
Select only the desired pin hole of and cut the pin material 4,
It cannot be inserted into the housing 3.

That is, there is an inherent drawback that the jump pin array cannot be assembled, and there is a problem that a step of removing unnecessary pins is required after inserting the pins to form the jump pin array.

[0013]

In view of the above-described conventional pin insertion mechanism, the present invention satisfies all the functions of the conventional connector assembling machine in the case of producing a connector of a normal type and continuously. It can be assembled at high speed, and when the housing pin arrangement requires a jump pin arrangement connector, it does not require the step of removing unnecessary pins from the completed connector, and it is added to the conventional one. Another object of the present invention is to obtain a jumper pin connector assembling machine that can easily achieve jump pin arrangement with such a mechanism and can continuously perform pin insertion work with a predetermined pin pattern.

[0014]

In order to solve the above-mentioned problems, according to the present invention, connector pins are inserted at a predetermined pitch on one of the upper surfaces of a pair of parallel rails connected to a component aligning and supplying apparatus. The transfer sliding contact surface of the plurality of housings was used, and the other was used as the transfer sliding contact surface of the hoop material in which the pin members were provided on the side edges at a predetermined pitch.

Further, by the lever on which the feed claw of the housing, the feed claw of the pin material and the head detection claw of the housing which are opposed to the sliding contact surface of the both are arranged, and the cam mechanism for regulating the feeding of the housing. A pitch feed mechanism for both the housing and the pin material was constructed.

Further, a connector assembling machine is constituted by a pin inserting head having a pin material cutter and a pin inserting hand, and the pitch feeding mechanism.

Further, a head detecting sensor is provided in the vicinity of the housing head detecting pawl, a solenoid having a pulling lever is attached to the pin material feeding pawl, and a basic pattern of the pin arrangement is input to the operation circuit of the solenoid. Incorporating a pin pattern setting mechanism.

In the solenoid operating circuit, an output signal to the solenoid is further calculated by the housing head pin position detection signal and the pin pattern setting mechanism signal, and corresponds to a predetermined pitch feed mechanism of the housing. A control device for controlling the feeding of the hoop material by the pin material feeding claw is incorporated to provide a flying pin connector assembling machine.

[0019]

The connector assembly machine for jumping pins of the present invention is a mechanical feeder for a connector housing and a pin material feeding mechanism, a pin material cutting cutter and a pin insertion hand mechanism, a housing head detecting mechanism, etc. in the conventional connector assembling machine. Since the stop mechanism is based on the base, the same function and the same components are adopted in this embodiment as in the conventional machine. As an example of installing two units in the assembly line of
The operation will be described.

When the housing and the pin material are continuously supplied to the housing rail and the connector pin material rail by the conventional parts aligning and feeding device, firstly, the pin incorporated in the first assembly line is assembled. In the insertion mechanism, the housing feed claw and the pin material feed claw attached to the lever are moved in the direction of movement by the operation of the lever that is arranged to move forward and backward along the rail.
A predetermined feed is given to the housing and the pin material at the same time, and the feed amount corresponds to a length of 2P, which is twice the pin arrangement interval P.

With respect to the mechanism for feeding the housing and the pin material at a predetermined pitch by the operation of the lever, the tips of the housing feeding pawl and the pin material feeding pawl are inserted into a recess on the lower surface of the housing through a cam follower that contacts the plate cam. By fitting, and on the other hand, by fitting in the feed holes arranged in the pin material at a predetermined pitch, both feed a predetermined feed.

The net feed amount of the transfer operation of the housing and the pin material by the operation of the lever is set by the shape of the plate cam that performs the operation of disengaging the toes of the both nails from the engaged state. When the cam portion of the plate cam comes into contact with the cam follower at the set length 2P portion, the toes of the two feed pawls are disengaged, and the feed of the set length 2P is completed. .

Regarding the feed corresponding to the adjacent portion between a plurality of housings which are continuously transported separately from the pitch feed 2P having a predetermined pin arrangement, the housing head detection pawl attached to the lever feeds the lever. By fitting into the groove arranged at the end of the housing, the next housing is moved until the pin insertion hole occupies the correct pin insertion position by more than the predetermined feed amount 2P, and the housing leading end detection pawl Slides on the housing except in the adjacent portion of the housing, and does not perform the action of the feeding operation.

Since a pin arrangement interval of 2P is set for one set of the pin insertion mechanisms, the second set of pin insertion mechanisms for the second set is phased with respect to the feed of the first pin insertion mechanism. Are arranged by shifting by 1P, and the arrangement is such that the even-numbered pin arrangement is performed and the odd-numbered pin arrangement is inserted, a housing having a predetermined pitch P arrangement is obtained, and in the assembly line. The pin array inserting operation at a predetermined pitch can be performed at a speed twice as fast as the operation by one set of the pin inserting mechanism.

The housing and the pin member are moved in parallel with each other by the forward and backward movement of the lever at the same pitch feed and the same phase, and the transfer operation is an intermittent operation of transfer and stop. In addition, the cutting of the pin material and the insertion operation of the pin material into the housing are performed at the time of stop, and the same mechanical transfer, cutting and insertion mechanisms as those of the conventional structure are adopted. Therefore, all the functions of the assembling machine can be satisfied even when a normal type connector is manufactured.

Next, in addition to the mechanical feed mechanism described above,
Corresponding to jump pin connector assembly by adding electrical detection, calculation, and output functions such as a pin pattern setting mechanism to the electrical lead detection sensor, solenoid that separates the pin material feed claw, and solenoid circuit The operation will be described.

The pin pattern of the connector is set as a reference of the pin arrangement in the setting mechanism, but in the detection mechanism, the feed positioning mechanism of the housing is adjusted for each pole number even if the number of poles of the housing is changed. In order to make the mechanism unnecessary, a rear reference housing positioning mechanism that aligns the rear end face of the housing is adopted, and the pin pattern with the rear side of the housing as the first pin is used as the toggle switch. Set with or digital switch. In the example, the pattern is ↑
Set as ↓ ↑ ↓ ↑ ↓ 0 ↓.

Next, in the pin inserting step, since two sets of pin inserting mechanisms are set, the pin pattern is divided into two.
In the embodiment, since the number of poles of the entire housing is eight and it is even, the first pin insertion head is allocated odd pins and the second pin insertion head is allocated even pins.

The housing top detecting claw is engaged with a groove provided at the end of the housing, and the next housing
When the pin hole of the housing moves to a position occupying the pin insertion position by more than the feed amount of P, the housing detection sensor is activated to electrically detect the head of the housing and then the lever feeds the housing at a predetermined pitch 2P. Each time the detection mechanism shifts the pin pattern by 1 bit.

In the detection mechanism, when the shifted pin pattern reaches the jumping pin position, the solenoid is excited by the arithmetic circuit and the pin material feeding pawl is removed from the pin material feeding hole via the pulling lever. Since the pin material feeding claw is idle-fed and the pin hole is brought to the position of the pin material that has already been cut and inserted, the pin is not inserted.

When the next shift has a pin, the solenoid is demagnetized by the arithmetic circuit, and the idle feed pin material feed pawl is again brought into a position to engage with the pin material feed hole, and the predetermined pitch 2P is set. It will be sent.

Therefore, at the next pole without jump pins, the housing and the pin material are simultaneously transferred at a predetermined pitch 2P,
At the stop time, the cut pins are normally inserted into the housing.

When the adjacent portion of the housing is moved by the predetermined pitch 2P feed, the housing leading edge detection claw is activated, and the transfer operation is performed to correctly feed the pin hole of the next housing to the pin insertion position. At the same time, the leading edge detection sensor operates. Due to
The shift of the pin pattern in the setting mechanism is returned to the head pin position.

After the pins are inserted into the housing by the first pin insertion head, the insertion operation is further performed by the second pin insertion head. At this time, one is a pin array with a normal pitch and the other is at the same time. Even with the pin arrangement of jump pins, if a pin pattern is set in advance in the detection mechanism, pin insertion with a normal pitch is performed on one side, and pin insertion with jump pins is performed on the other side.

The housing in which the pin is inserted by the second pin insertion head becomes the housing of the connector in which the pin insertion is completed based on the pin pattern, so that it is transferred to the setting mechanism constituting the inspection section by a conveyor or the like. The pin pattern of the setting mechanism set by the toggle switch or digital switch and the pin arrangement of the pin are assembled and compared and inspected, and defective products are discarded, and jump pin connectors with free pin patterns are continuously connected. Can be produced.

1 to 4 show an example of an embodiment of a jump pin inserting mechanism of the present invention applied to a connector assembling machine for a printed circuit board. The components, components, etc. shown in the drawings are as follows. The same components and parts as those of the conventional one will be described with the same reference numerals and the same names.

FIG. 1 shows an outline of the structure of the jumper pin connector assembly machine. In the figure, reference numeral 6 is a rail of a housing 3 of the connector, and reference numeral 5 is a hoop forming a pin material 4. The rails of the material 7, wherein the upper surfaces of the rails 5 and 6 are parallel to each other, and are connected to a parts aligning and feeding device (not shown in the drawing). The transfer sliding contact surfaces 34 and 35 are used.

The rails 6 and 5 are used not only to supply the housing 3 and the hoop material 7 from the component supply device, but also to transfer the housing 3 and the hoop material 7 which will be described later, and from the hoop material 7. It is configured to serve as a transfer table which is a base portion of each step such as cutting the pin material 4 and inserting the pin material 4 into the housing 3.

A lever 8 which faces the rails 6 and 5 and which feeds the housing 3 and the hoop member 7 with a predetermined pitch P is arranged so as to be able to move back and forth in the transfer direction X and the return direction X'of the both. ing.

On the lever 8, on the one hand, a housing feed pawl 12 is arranged below the housing 3 to be transferred, and on the other hand, a housing head detection pawl 16 is arranged above the housing 3, The feed pawl 12 is swingably arranged via a fulcrum pin 14 toward a recess 24 on the back side of the housing 3, and the leading detection pawl 16 is inserted into a groove 22 at the front end of the housing 3 via a fulcrum pin 17. The claws 12 and 16 are arranged so as to swing toward each other.
The leaf spring 26 facilitates the depression 24 and the groove 2.
It is biased to mesh with 2.

The lever 8 has a pin material feeding claw 13
Are arranged above the feed holes 21 arranged in parallel with the leading edge detection claws 16 at the side edges of the hoop material 7 at a predetermined pitch P, and swing toward the feed holes 21 via the fulcrum pins 15. It is movably arranged and is biased by a leaf spring 26 so that it can be easily meshed with the feed hole 21.

When the toe tips 23, 23 of the housing feed claw 12 and the pin material feed claw 13 move in the direction of arrow X as the lever 8 moves forward and backward, the housing 3 and the hoop material are moved by a cam action described later. 7 is moved forward, and on the other hand, when moving in the direction of arrow X ', the housing 3
And the hoop member 7 has a claw shape that can slide on the surface of the hoop member 7, and therefore the frictional force between the transfer sliding contact surface 35 and the housing 3 and between the transfer sliding contact surface 34 and the hoop member 7 is the same. Since it exceeds the resistance of the toes 23, 23 of the Nos. 12 and 13, the housing 3 and the hoop member 7 are stationary at the advanced position.

The pitch size of the recesses 24 arranged on the back surface of the housing 3 and the pitch size of the feed holes 21 arranged in the hoop material 7 are the same, and the lever 8
The cam mechanism 30 associated with the forward movement of the claws 12 and 13 determines the engaging and pushing lengths of the pawls 12 and 13 with respect to the housing 3 and the hoop member 7, and a predetermined feed pitch dimension can also be determined by adjusting the engaging and pushing length. In the present embodiment, since the two jumping pin insertion mechanisms 1 and 2 are arranged in one working line, the two pitches of the pin material 4 correspond to the housing 3
It is said that the feed amount is one time.

The housing feed claw 12 and the pin material feed claw 13 are in rolling contact with the plate cam 18 as the fixed cam of the cam mechanism 30 shown in FIG. 3 via the cam follower 19, and the cam follower 19 is brought into contact with the non-cam surface 27. When brought into close contact, the toe 23 is engaged with the concave portion 24 of the housing 3 or with the feed hole 21 of the hoop member 7, and when brought into close contact with the cam surface 28, it is disengaged. Therefore, the feed length of the housing 3 and the hoop member 7 is determined by the length of the non-cam surface 27 of the plate cam 18, and the pawls 12 and 13 are not meshed with each other in the transfer operation of the lever 8 on the cam surface 28 as described above. From the claws 12, 1
Since the cam length is determined by the meshing length of 3, the shape of the cam is set by a preset feed amount.

Regarding the feed corresponding to the adjacent portions between the plurality of housings 3, the housing leading edge detection claw 16 is meshed with the groove 22 as described above, and the next housing 3 is moved.
Is fed more than the feed amount of the preceding housing, and is moved to a position where the pin hole of the next housing 3 occupies the pin insertion position is the same as the conventional one.

As shown in FIG. 1, the cutter 9 having the toes parallel to the end faces of the plurality of pin members 4 projecting from the hoop member 7 at a predetermined pitch P is located at the origin position of the cutter 9. And a pin member 4 by the pin inserting claw 10 when the transfer of the hoop member 7 is stopped when the hoop member 7 is stopped from moving forward and backward in the arrow X direction, which is the transfer direction, on the same projection plane as the stop position B of the pin inserting claw 10 described later. Between the cutting position of the pin material 4 which is the same position as the clamping position c of
The pin insertion claw 1 is vertically movable in the direction of arrow ZZ.
It is arranged to be operated in relation to zero operation.

The pin insertion claw 10 shaped to clamp the pin material 4 by a pair of upper and lower claws is located at the transfer stop position of the pin material 4, and is clamped to the pin material 4 and the escape position e. A pin set between the clamp position C and the insertion position into the housing 3 is movable in the direction of the arrow Y-Y in FIG. 1 on the projection plane and is set in the process of assembling the pin material 4 and the housing 3. Between the drop distance between the transfer position level of the material 4 and the transfer position level of the housing 3, that is, between the clamp position c of the pin material 4 and the position h of the same height as the insertion position of the pin material 4 into the housing 3. Are vertically movably arranged in the vertical direction, and as described above, the clamping and cutting operations of the pin material 4 and the inserting operation of the clamped pin material 4 into the housing 3 are correlated in the transfer stop time of the both. Divide.

Therefore, again the housing 3 and the hoop material 7
Is moved by a predetermined amount and then stopped, the cutting of the pin material 4 and the insertion into the housing 3 are continuously performed, and the housing in which the pin material 4 is inserted for each pole by the first pin insertion head as described above. 3 is the next pin insertion head and 1P
The pin material 4 for each of the displaced poles is inserted.

The drive of the cutter 9 and the insertion pawl 10 which are provided with the housing feed pawl 12, the pin material feed pawl 13, and the housing head detection pawl 16 and which constitute the lever 8 and the pin insertion head are not shown. The structure is such that it is driven by a plurality of cams arranged on the same drive shaft.

In the mechanical pitch feed mechanism 36 including the mechanical housing feed pawl 12, the pin material feed pawl 13, the housing detection pawl 16 and the like described above, the pin insertion is performed continuously by a normal pin arrangement without jump pins. However, in order to deal with the pin pattern having the jump pin arrangement, the pin insertion mechanism to which the electric control device is added as described above will be described.

At the same time that the front end detection sensor 29 for electrically detecting the front end of the housing simultaneously with the detection of the groove 22 on the end face of the housing 3 by the front end detection pawl 16 is close to the front detection pawl 16, the lever 8 is provided. It is installed in.

Control is performed by a pin pattern setting mechanism, which will be described later, and a solenoid 33 having a correlation with the mechanism, a pull-up lever 32 connecting the solenoid 33 and the pin material feed claw 13, and the housing head detection sensor 29. A device 31 is configured and arranged on the lever 8. When a signal indicating a jump pin position is output from the setting mechanism to the solenoid 33, the solenoid 33 is released.
Is excited, and the pin material feeding claw 13 is moved through the lever 32.
Is detached from the feed hole 21 of the engaged hoop material 7, and the pin feed is stopped.

As shown in the block diagram of FIG. 4, the pin pattern setting mechanism divides a predetermined pin pattern into two sets of pin patterns and divides the two pin insertion heads into operations in this embodiment. The head detection sensor 29 has a storage calculation output function for calculating the signal as shown in the flow chart and outputting it to the solenoid 33 to perform a pin insertion operation at a predetermined position in the jump pin array.

Further, in the pin pattern setting mechanism, in order to eliminate the need to adjust the housing 3 positioning mechanism for each pole number even if the number of poles of the housing 3 is changed, a rear reference feeding mechanism of the housing 3 is adopted. ing. That is, since the transfer start position of the housing 3 by the housing feed claws 12 is always operated with the rear end of the housing 3 as a reference, if the reference feed of the housing 3 is rearward even if there is a change in the number of poles, the pin pattern is set backward. You can set the side as pin 1.

In the mechanical feeding mechanism based on the rearward reference feeding, when the housing 3 easily slides on the rail 6 due to the inertial force associated with the transfer operation, which causes a hindrance to the overall positioning,
The brake device is installed in consideration of applying a brake load to the housing 3.

Since the pin insertion operation into the housing 3 is performed on the basis of the head, the number of pin assignments of the pin insertion head differs depending on whether the total number of poles is even or odd.

In the embodiment, when the number of pin poles is eight, the total number of poles is an even number.
Then, because of the head reference, the allocation is odd-numbered pins, and the subsequent pin insertion head 26 is allocated even-numbered pins.

For example, when the number of pin poles is 8, the pin pattern is ↑ ↓ ↑ ↓ ↑ ↓ 0 ↓ as the rear reference of the housing, the rear side is the first pin, the second is 0, and the pin is 0. It shows the position of a jumping pin without a pin, and the pins from 3 to 8 are inserted thereafter. To store in the control function based on this pin pattern, the housing is set by the toggle switch or digital switch in the setting mechanism panel. Pin patterns are sequentially set from the rear side of 3.

When the pin pattern is divided into two as described above, and one of the pin patterns is assigned to the pin insertion head 2a as ↑↑↑ 0 first, an odd-numbered pin from the head of the housing 3, that is, 1, 3, 5, 7
The pin of the second pin arrangement is selected, the first pin on the rear side becomes 0, and it is displayed as a jumping pin.
The second pin is an insertion pin.

In this setting mechanism, when the groove 22 of the housing 3 is detected by the housing leading edge detecting claw 16 and the leading edge detecting sensor 29, the next housing 3 is mechanically fed. The first pin hole of the head reference is moved to the pin insertion position, and at the same time, the head is electrically detected by the head detection sensor 29, and is divided into two parts for each feeding of the housing 3 according to the block diagram shown in FIG. The pin pattern is shifted by one digit.

When the shifted pin pattern reaches the jumping pin position, the solenoid 33 is excited and the pin material feed claw 13 is pulled up via the lever 32, and the feed hole 21 of the hoop material 7 is pulled out. When the pin material feeding claw 13 is detached, it is idly fed.

Next, when the next shift has a pin, the solenoid 33 is demagnetized, and the idle feed pin material feed claw 13 is engaged with the feed hole 21 of the hoop material 7, and the housing 3 at the next pole. The hoop material 7 and the hoop material 7 are simultaneously fed at the same pitch, and the cutting of the pin material 4 and the insertion of the pin into the housing 3 are normally performed.

Next, when the adjacent portion of the housing 3 comes, the housing leading edge detection claw 16 is operated, the leading pin hole of the next housing 3 is moved to the pin insertion position, and at the same time, the signal from the leading edge detection sensor 29 is sent. As shown in the flowchart, the pin pattern moves to the beginning, and then the pin insertion is performed.

If the pin insertion head 2a has completed the pin insertion and the other pin insertion head 2b has the pin pattern ↓↓↓↓ as described above, the even-numbered pins from the top of the housing, that is, 2 , 4, 6th and 8th pin arrangement pins are selected, and the 4th, 6th and 8th pins are sequentially inserted from the 2nd pin on the front side without skipping pins.

However, the other pin inserting head 2b can also be made to jump pins at the same time by setting the pin pattern in advance in this way.

Therefore, the housing 3 in which pin insertion is completed by the pin insertion head 2b is transferred to an inspection section having the same structure as the setting mechanism by a conveyor or the like, and the pin pattern set by the toggle switch or digital switch is completed. The pin pattern of the connector that has been removed is checked, and the defective product is discarded. Therefore, according to the jumping pin insertion mechanism, it is possible to continuously produce a jumping pin connector having a desired free pin pattern.

[0067]

According to the present invention, in addition to the conventional pin insertion mechanism, the head detection sensor for detecting the housing head position, the solenoid and the jump pin arrangement for giving the operation of pulling the pin material feeding claw away from the hoop material when the jump pin arrangement is adopted. By arranging a pin pattern setting mechanism that stores a basic pattern and gives an output corresponding to jump pins to the solenoid, all the functions of the conventional assembly machine can be satisfied, and even when assembling a connector without jump pins. A sufficient assembly effect can be obtained.

Moreover, in the case of the jump pin arrangement, a predetermined pattern can be freely set by the pattern setting mechanism,
By inputting a pattern corresponding to a predetermined jump pin arrangement of the housing, desired pin feeding can be performed, and pin insertion can be easily stopped according to the jump pin position.

If two pin insertion mechanisms are arranged for the jumper connector assembly machine for one line, the pin pattern can be divided into two and the pattern setting mechanism can be input by a toggle switch or the like. The position of the jumping pin can be any position, and if the housing and pin feed are also doubled the predetermined feed pitch, the feed speed in the line will be doubled, which will greatly improve productivity. In addition, it is possible to eliminate the difficult and troublesome work of inserting the jumping pin and pulling it out after completion as in the conventional case.
