Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal inspecting device for a connector used for inspecting an inserting state of a wire terminal housed in a connector and an inserted state of conductivity.

[0002]

2. Description of the Related Art Conventionally, the above-mentioned connector terminal inspection device is
There are known examples such as Japanese Utility Model Publication No. Sho 53-18545 and Japanese Utility Model Publication No. 55-8221, which commonly have an inspector main body with a connector fitting portion on the front face, and a plurality of inspections on the main body. The pins are juxtaposed in parallel with each other so that their tips are opposed to the connector, and the inspection pins are biased toward the connector and are bisected by an intermediate interval. When contacting and retreating, the inspection pin, which is divided into two parts, comes into contact with the circuit to conduct the circuit, and the required inspection is performed.

[0003]

However, according to the first conventional example, Japanese Utility Model Publication No. 53-18545, after the connector C to be inspected is fitted to the pin 3 of the main body 1, the main body 1 is rotated. To connect the connector C to the main body 1 and the guide plate 2.
The connector and the pin 3 are press-fitted and fixed between the three to make complete contact, but when the connector is fitted to the main body, the connector is in a free state and easily sways, and the main body is also rotatable. An oblique force was applied to the pin and the device was apt to be painful, and the force required for the press-fitting was large and difficult.

Next, a second conventional example, Japanese Utility Model Publication No. 55-822.
In No. 1, after the connector A is preliminarily attached to the support plate 2, the lever 17 is operated to slide the inspector body 1 forward and backward by the cam 9 to clamp the connector between the body and the support plate. Then, the connector and the pin 11 are brought into contact with each other. This prevents an oblique force from being applied to the pin and reduces the operating force by operating the lever, thereby attempting to eliminate the drawbacks of the first conventional example.

However, even in the second conventional example,
Since the connector A is simply fitted into the hole of the single-plate-shaped support plate 2 and is attached in a cantilever manner, there is a risk of rattling and attachment of the connector. In this state, the connector A is fitted into the pin. Then, the inspection pin or the terminal of the connector is easily damaged.

[0006]

A terminal inspection device for a connector according to the present invention for solving the above problems comprises an inspection section 2 and a connector holding section 3 provided so as to face the inspection section 2. In a terminal inspecting device for a connector, in which any one of the inspection unit 2 and the connector holding unit 3 is movable relative to the other in the front-rear direction so that the connector holding unit 3 is a holding plate unit. 8 and positioning frames 22A, 22B that extend from the holding plate portion 8 in the direction of the inspection unit 2 and that face each other by contacting both sides of the connector to regulate the position of the connector.

[0007]

With the above-described structure, the connector has the holding plate portion 8 and the positioning frames 22A, 22 on both sides with respect to the connector holding portion.
The probe is fitted and housed in a substantially U-shaped space composed of B and supported from three sides, so that the holding posture is stable, the positioning accuracy is improved, and the connector does not rattle. Or, there is no fear that the terminals of the connector will be damaged.

Further, if the engaging portions 5a and 22C of the connector and its holding portion are engaged with each other, the connector and the holding portion can be accurately positioned without rattling.

[0009]

Embodiments will be described in detail below with reference to the drawings. 1 to 3 showing an embodiment thereof, in a terminal inspector of the present invention, an inspection unit 2 having an inspection probe 9 inserted therein is mounted at an intermediate position of a groove-shaped underframe 1 having a U-shaped cross section. The inspection unit 2 is movable in the front-back direction of the underframe 1. In front of the inspection unit 2, a connector holding unit 3 facing the inspection unit 2 is fixed to the front end portion of the underframe 1.

The connector holding portion 3 comprises a front holding plate portion 8 and a pair of positioning frames 22A and 22B. The positioning frames 22A and 22B substantially extend rearward from both side portions of the holding plate portion 8 and face each other, and an upper opening portion 32 and a rear opening portion 33 are formed above and behind them, respectively. Therefore, when the connector 5 is mounted and housed in the connector holding portion 3 from above through the upper opening portion 32, the connector 5 rattles in the substantially U-shaped space formed by the positioning frames 22A and 22B and the holding plate portion 8. Accurately positioned without Further, at this time, the protrusion 5a of the connector 5 is slidably engaged with the recess 22C of the positioning frame 22A so that the positioning frame 2

At this time, the electric wire 14 of the connector 5 is loosely inserted into the opening 7 of the holding plate 8, and as shown in FIG.
The rear end of the connector 5 has a rear opening 33 of the connector holder 3.
To the rear, that is, to the inspection unit 2.

On the other hand, behind the inspection unit 2, there is a lever-shaped operation lever 10 which is erected at the rear end of the underframe 1, and the operation lever 10 is connected to the inspection unit 2 via a link 12 attached to its operating point. The operating lever 11 is connected to the operation shaft 11 at the rear end.
0, the link 12 and the actuating shaft 11 constitute the operating portion 4, and the pushing and pulling force amplified is applied to the inspection portion 2 by the forward tilting and standing of the operating lever 10, and the inspection portion 2 is placed on the underframe 1. To move back and forth. In the figure, 20 is the operating shaft 11.
Is a guide.

More specifically, as shown in FIG. 2, the inspection portion 2 has a recess 16 into which the rear portion of the connector 5 is slightly fitted.
There is a through hole extending in the front-back direction of the inspection unit 2 in the bottom wall of the recess 16, and the inspection probe 9 is inserted therein.
The head is projected and inserted into the recess 16. A large number of inspection probes 9 are arranged corresponding to the positions of the terminals 13 accommodated in the connector 5 to be inspected.

As shown in FIG. 3, the inspection probe 9 is housed in the metal tube body 31 and is composed of a pair of slidable front probe 17A and rear probe 17B. The front probe 17A and rear probe 17B are individually arranged. In the free state, a small gap G is interposed between the rear end of the front probe 17A and the front end of the rear probe 17B to separate them from each other.

That is, the front half of the front probe 17A is housed so as to project from the metal tube 31, and the rear half of the front probe 17A is provided between the step portion 17 'in the middle and the front end of the metal tube 31.
8A is attached and urged forward, and when it is free, it stops at the position shown. Further, the rear probe 17B has a front half portion inside the hollow portion of the metal tube body 31, and the rear half portion is inserted into the metal outer sheath tube 19 in series with the coil spring 18B, and the front end portion of the outer sheath tube 19 is provided with the insulating material 21. It is fixed to the metal tube body 31 via the. And the rear probe 17B
Is urged forward by a coil spring 18B in the outer tube 19, and when it is free, it stops at the position shown in the figure, and the gap G is interposed between it and the front probe 17A.

That is, the inspection probe 9 is the common metal tube 3
1, the front probe 17A for accommodating the latter half portion and the rear probe 17B for accommodating the front half portion are arranged in series and individually biased forward, and the front probe 17A is moved forwards and backwards in the metal tube body 31 for sliding between metals. The rear probe 17B is freely accommodated, and the rear probe 17B is accommodated in the metal outer tube 19 attached to the metal tube body 31 via the insulating material 21 so as to be able to slide back and forth between the metals so that the entire body is unitized. ing.

Therefore, when free, the front probe 17A
And the rear probe 17B are separated from each other through the gap G, and the front probe 17A is retracted to move the rear probe 17B during inspection.
The structure is such that it makes contact with B and conducts electricity.

In the terminal inspecting device of the present invention having the above-mentioned structure, the connector 5 to be inspected is mounted from above the connector holding part 3 as shown in FIG. The amplified pushing force is applied to the position 2 to move forward, and the rear end portion of the connector 5 is fitted into the recess 16 in the front thereof. If the connector 5 has the terminal 13 in the normal insertion posture, the probe 17A interferes with the terminal 13 and therefore resists the bias of the coil spring 18A.
1 and retracts to contact the rear probe 17B.

Thus, when the electric wire 14 of the terminal 13 and the electric wire 15 connected to the outer tube 19 of the rear probe 17B are connected, the circuit passing through the terminal 13 becomes conductive, and it can be confirmed that the electric conduction performance is good. Further, if the terminal 13 is out of stock or has a bad attitude, the above-mentioned conduction becomes impossible and a defective product is confirmed.

In particular, in the connector inspection of a multi-pole high-density terminal, even if the front probe 17A is inserted into the narrow terminal cavity of the connector 5, there are problems such as posture collapse and inability to contact the terminal due to interference with the cavity. It does not occur, and good connector terminal inspection can be performed efficiently.

[0021]

The connector 5 includes the holding plate portions 8 and 1 of the connector holding portion 3.
Since it is fitted and mounted in the substantially U-shaped space formed by the pair of opposing positioning frames 22A and 22B and supported from three sides, conventionally, it is simply cantilevered in a single plate-shaped connector holding portion. Compared with the case of holding, the holding posture is stable and accurate positioning is performed, so it is not necessary to check the position of the connector or correct the position, which can reduce the number of work steps and improve the work accuracy. obtain.

Therefore, when either the inspection unit 2 or the connector holding unit 3 is relatively moved and the inspection unit 2 is pressed against the connector and pressed against the holding plate unit 8, the connector rattles and is inspected. There is no risk of damage to the terminals of the probe or connector, or failure of inspection.

If the connector 5 and the connector holding portion 3 are provided with the engaging portions 5a and 22C, respectively, and are engaged with each other, the connector can be positioned with respect to the holding portion 3 extremely accurately and without rattling. Therefore, it is possible to further reduce the number of working steps and further improve the positioning accuracy of the connector.
