Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and device for assembling connector contacts connected to core wires at both ends of a multi-core cable or a large number of discrete electric wires into a connector housing. .

When assembling the contacts of this type of connector into a connector housing, conventionally, as shown in FIG. , solder connection, wrapping connection, insulation displacement connection, etc.
A connector with wiring is assembled by inserting the contacts 4A and 4B into the contact holes 3A' and 3B' into the multiple contact holes 3A' and 3B'. It depends on human hands. That is, corresponding to the contact 4A that is first inserted into the contact hole 3A' of one connector housing, the contact 4B connected to the other terminal is inserted into the other connector housing 3B.
Accurately inserting and assembling the contact hole 3B' into the contact hole 3B' is a very complicated operation, which often results in incorrect assembly, and relies solely on the skill and intuition of the operator. Particularly in the case of multi-polar connectors or connectors with long wire lengths, the above-mentioned drawbacks are exacerbated because it is inconvenient to check the wiring at both ends of the wire.

Furthermore, in conventional electrical circuits such as electrical devices, when you want to change part of the circuit without changing the basic pattern of the circuit, or when creating a new circuit by using the conventional printed circuit board as is. In such cases, the circuits of multi-core cables and discrete electric wires connected by connectors, which are peripheral circuits, are often changed. In other words, the connection between the multi-core cable or discrete electric wire and the connector must be crossed. For an example of that connection,
To explain FIG. 2 of the attached drawings, the core wires 2 at both ends of the multi-core cable or discrete electric wire 1
A, 2B are connected to the contacts 4A, 4B of the connector housings 3A, 3B. In that case, normally the same number wires are connected to the contacts of the connector housings 3A and 3B, but as mentioned above, cross connections are made. When necessary, wire numbers 2 and 3 are connected by crossing them, as in the connector 3A shown in FIG.

The above example is a simple wiring in which wire numbers 2 and 3 are crossed, but there are actually many other types of complicated cross wiring. Conventionally, even in such complicated cross wiring, cross wiring was carried out by visually reading the wires manually. This makes the installation work more difficult and causes incorrect wiring, resulting in unreliable wiring.

The purpose of the present invention is to eliminate the drawbacks of the conventional wiring method, and to make it possible to connect the correct contact hole of the connector housing even with complicated wiring or complicated cross wiring, without relying on the operator's visual inspection or intuition. An object of the present invention is to provide an assembly method and apparatus for inserting and assembling contacts.

Next, the principle of the present invention will be explained based on the accompanying drawings.

Figure 1 shows a multi-core cable or a large number of discrete electric wires 1 with contacts 4A and 4B randomly connected to the core wires of both ends 2A or 2B using an automatic crimping machine or an automatic pressure welding machine. Terminal core wire 2
The contacts 4A connected to A are randomly inserted into the contact holes of one connector housing 3A. Various techniques for randomly inserting the contacts 4A into the contact holes of the housing 3A of one connector have been disclosed in the past, and since they are not the main focus of the present invention, they will only be briefly described below.

In Fig. 3, contacts 4 are randomly inserted into the contact holes of one connector housing 3A in Fig. 1.

The touch sensor 7 of the connection detector 6 is touching the other end 2B of the cable core or the contact 4B. In this state, when the connected contacts 4A of the cable core terminal 2A are scanned by the scanner of the connection detector 6 through the connection box 10, the terminal 2
B or contact 4B is touched by the touch sensor 7. Since the core wire is different in capacitance or impedance from other core wires that are not touched, the terminal 2A of the touched core wire is connected. Connector assembly allows you to know the wire number of the contact that is connected, and this wire number is displayed on an indicator such as an LED of the wire connection detector 6, and the electrical signal from the wire connection detector 6 will be explained in detail later. By driving the pulse motor of the device, the position of the contact hole of the other connector 3B is determined, and if the contact 4B whose number wire has been detected is inserted into the contact hole 5B, it is definitely inserted into the one connector housing 3A. By performing this operation for the contacts 4B of all the connectors 3B, which are inserted into the contacts 4B and the other connector 3B, the connectors 3A and 3B with correct wiring at both ends can be completed.

Next, the operation of the apparatus for assembling a contact into a connector housing constructed as described above will be explained in sequence according to the flowchart shown in FIG.

(1) Peel off the outer sheath from both ends of cable 1, and remove core wire 2.
Separate A and 2B.

(2) Hold the cable 1 with the outer sheath peeled off using the wire holding arm 20.
0B, and the terminal side to be incorporated into the connector housing is held by the cable holding part 146.

(3) Turn on the power using the power switch 121 of the control box 120 provided in the device.

(4) Determine the pitch of the contact holes in the connector housing using the connector type switch 191 provided in the operation box 190. That is, this connector type switch 191 stores the X-axis pitch and Y-axis pitch of standard and frequently used connectors in the main memory (RAM) of the multiple types microcomputer 190A. In actual work, what is stored in this microcomputer is used to drive a pulse motor via a central processing unit (CPU), and by switching the connector type switch 191, it is possible to incorporate many types of connectors.

(5) Connector housing 3A to be assembled next
into the connector groove 132 of the connector housing moving base 130. and operation button 190
When the single pitch feed button 192 (sequential feed by the same pitch as the contact pitch) button 192 is pressed, the connector housing 3A is firmly attached to the moving table 131. However, in this case, a recess 133A is provided on the connector clamp 133 side in consideration of the number of poles, size, etc. of the connector housing so that various connector housings can be attached thereto, and the number of poles and model name 133B are written thereon. Furthermore, the connector clamp 133 can be easily attached and detached, so that it can be used not only for square connectors but also for round connectors and the like. The circular connector will be explained later.

(6) After confirming that the connector housing 3A is attached to the connector clamp 133, press the start button 193 of the operation box 190, and the X-axis pulse motor 150 drives the moving table 131 to the original position, which is the origin. Move to the contact hole position, and then move the Y-axis pulse motor 1
60 moves the contact insertion grooved cover 140 along the Y-axis to the position of the first contact hole, and the contact insertion groove 141 attached to the cover 140 corresponds to the contact hole to randomly insert contacts. Can be inserted and assembled. When the contact 4A of the housing is completely and accurately inserted, the air cylinder 142 is actuated by a touch sensor or optical sensor (not shown), and the lead wire moving arm 143 receives the lead wire made of an elastic material. It is stored in the open hole 134A. However, in this case, since it is only inserted randomly, other methods may be used to incorporate it.

(7) Next, the X-axis pulse motor 150 moves to the contact insertion groove 141 in accordance with the pitch of the next contact hole 3A', and the contact 4A is inserted into the contact hole 3A' in the same manner as described above.
In this way, all contact holes 3 on the X axis
The contact 4A will be inserted into A'. Similarly, when the terminal hole row in the X-axis direction is not just one row but multiple X-axis rows, for example, second row, third row, etc., the Y-axis pulse motor 160 moves the contact insertion grooved cover 140 in the Y-axis direction. All the contacts 4A are assembled into the connector housing 3A by transferring each row and by using the X-axis pulse motor to transfer the moving table 131.

(8) When the contacts 4A are assembled into all the connector housings 3A according to (7), the connector housings 3A are removed from the connector clamp 133 and connected to the coupling connector 11 of the detector connection box 210. Then, the cable 1 is held by the cable holding portion 146 so that the terminal end of the cable 1 can be assembled.

(9) Line selection switch 19 of operation box 190
Press 4 to securely attach the connector housing 3B using the connector clamp 133, and set the X-axis pulse motor 150 and Y-axis pulse motor 160 to operate by selecting the wire number.

(10) Next, when the start button 193 is pressed and any contact 4B of the cable 1 is grabbed by hand, the detector 170 scans it, selects the number line, and automatically sends the signal from the detector to the X-axis and The Y-axis pulse motor is driven, and the contact hole 3B' of the contact housing 3B is set at the set position, and the contact 4
The assembly is performed by inserting B into the contact hole 3B'.

(11) Next, as in (10), any other contact 4B is grabbed and all the contacts 4B are assembled into the contact housing 3B. Then, only the necessary wire numbers are cross-wired by the cross-wiring means.

(12) With the above steps, the contacts at both ends of the cable 1 are assembled into the connector housing.Next, the cable 1 is held by the wire holding arm 230A,
The connector at one end of the cable 1 is connected to the connector test connection box 220A, and the connector at the other end is connected to the front end connector 11 of another connector test connection box 220B, and continuity and voltage withstand tests are performed.

Through the above operating procedure, the connector can be assembled repeatedly, the cable can be assembled reliably, and mass production can be carried out.

In addition, although the above explanation has been given only for a square connector, even a round connector 30B as shown in Fig. 11 can be easily assembled by reading the position of the contact hole 30B' in the X and Y directions and transferring it in the X and Y axis directions. is possible.

In this case, if the contact pitch of the round connector 30B is not stored in the main memory (RAM), replaceable (cassette) type round connector 30B
It is necessary to switch to a contact pitch dedicated memory (ROM) and also change the connector type switch to the switch 191A dedicated to round connectors.

Furthermore, the above explanation is based on the microcomputer 1.
Regarding the pitch transfer of the X and Y axes stored in the RAM of the 90A, there is a connector that is installed without being stored in the microcomputer 190A, that is, contact holes that are not regularly arranged on the X and Y axes. In order to accommodate special connectors with It can also be integrated with a connector.

Next, with reference to the block diagram of the control circuit shown in FIG. 9, the assembling of contacts in the case of single pitch feeding and the assembling of contacts in case of number line selective feeding will be described in detail.

In FIG. 9, first press the single pitch feed switch 192 for setting work conditions, then press the start button 193, and the X-axis pulse motor 150 and Y-axis pulse motor 160 are activated via the CPU.
Connector housing 3A due to RAM memory
further move the contact insertion grooved cover 14
0 and is stopped at the contact hole 3A' which becomes the origin. When the contact 4A is inserted into the contact hole 3A', the optical sensor 250 (or touch sensor) confirms that the contact has been inserted normally, and the signal is transmitted to the detection section 251. The X-axis pulse motor 150 or the Y-axis pulse motor 160 drives only one pitch of the next contact hole 3A'.

In this way, the single pitch moves the connector housing 3A and the contact insertion grooved cover 140 by the X-axis pulse motor 150 or the Y-axis pulse motor 160, and the contact 4A is assembled.

In FIG. 9, when all the contact holes 4A of the connector housing 3A have been assembled by the single pitch feed described above, the connector housing 3A is connected to the coupling connector 11 of the detector connection box 210, and the next operation is performed. As a condition, if you press the wire selection switch 194 and the start button 193, and then touch any one of the contacts 4B at the other end of the cable with the touch sensor 7, the switch for that core number will operate, and the switch for which wire will be activated. It scans to see if it is activated and uses it as an electrical signal for the touch scanner. The electrical signal is amplified by an input interface.
X-axis pulse motor 150 and Y-axis pulse motor 16 via CPU and output interface
0, both motors are driven, and a lead wire can be inserted into the contact hole. Further, a signal indicating the number line is transmitted from the CPU to the number line display 240 using an LED display and displayed. As a result, the operator can visually know which number line has been selected from the number line indicator 240.

On the other hand, when the start button 193 is pressed, the X-axis and Y-axis pulse motors 150, 160 are driven via the CPU in response to this, and the connector housing 3B and the contact insertion grooved cover 140 are moved. As a result, the contact 4B can be easily assembled into the contact hole 3B' of the connector housing 3B.

The method and apparatus for assembling a cross-wiring contact into a connector housing according to the present invention are as described above, and have the following effects.

In cross wiring, it is no longer necessary for the worker to visually select the number of core wires, and the fatigue of the worker is significantly reduced.

The operator can cross-wire by simply grabbing any contact and inserting it into the contact hole, so the work is extremely easy, as it does not require any skill and does not rely on intuition. This can be done quickly and easily by anyone, eliminating the possibility of incorrect installation.

Even if the multi-pole connector or the wire is very long, the work remains the same and can be done easily as described above.

Mass production is possible because a series of tasks can be completed in a short period of time.

By simply replacing the cross wiring of the cross wiring means as appropriate, any cross wiring can be easily performed always in the same procedure.

Effects of the second embodiment The cross wiring 200 of the first embodiment crosses a pair of connectors having the same number of poles as the connector connected to the cable 7 using the electric wire 201 to the contacts of the required wire number. Since it is difficult to manufacture this one pair of cross wiring connectors, if you have many different types of cross wiring, it is necessary to prepare the same number of one pair of cross wiring connectors each time. I needed to make one.

However, in the case of the keyboard 400 of the second embodiment, the communication hole 402 of the keyboard 401 is
Cross wiring can be easily and quickly rearranged simply by replacing the key 410.

Effects of the third embodiment The third embodiment exhibits even better effects than the second embodiment. In other words, it is possible to more easily and quickly switch the cross wiring simply by operating the slide switch in any X column.
