The housing seating part 210 is a housing that is seated, and is formed as a recess recessed in one surface of the dedicated jig 200. At this time, the housing seat 210 is formed similar to the shape of the housing 300 so that the housing 300 can be stably seated on the housing seat 210.

The clamp 220 is for fixing the housing 300 to the housing seating portion 210 and is formed through the side surface of the dedicated jig 200. The clamp 220, as shown in Figures 5 to 7, the gripping portion 221 protrudingly formed on the side of the dedicated jig 200 and the binding portion 222 inserted into the housing seating portion 210 Is formed. The gripping portion 221 and the binding portion 222 are formed by bending both ends of the clamp 220 in opposite directions, and are inserted into and coupled to the side surfaces of the dedicated jig 220. The binding portion 222 inserted into the housing seating portion 210 contacts the side surface of the seated housing 300 to fix the housing 300. At this time, the clamp 220 is coupled with a pin or the like at the point P so as to be rotatable. Then, when the operator presses the gripping part 221 in the direction of the arrow shown in FIG. 7 (b), the clamping part 222 rotates around the point P, and the binding part 222 is inside the housing seating part 210. Is moved from outside to outside.

The clamp 220 may return to the original position when the gripping part 221 is pressed and released. To this end, the clamp 220 may additionally constitute a spring (not shown) that presses the gripping portion 221 from the inside of the dedicated jig 200 to the outside of the dedicated jig 200. Alternatively, a spring may be configured at the point P to have the property that the clamp 220 is to be fixed at a certain position.

By forming the clamp 220 formed as described above, the housing 300 may be coupled to the dedicated jig 200 by preventing upward movement of the housing 300 seated on the housing seating portion 210.

As the fastening part 230 is coupled to the common jig 100, as shown in FIG. 8, it is composed of an insertion column 231 and a fastening protrusion 232.

The insertion column 231 is inserted into the insertion hole 111 of the coupling portion 110 to be described later, and is formed to protrude on one side of the dedicated jig 200. In more detail, it is preferable that the insertion column 231 is formed to protrude from the opposite side of one side on which the housing seating portion 210 is formed. In addition, it is preferable that the insertion column 231 is formed of a cylindrical column having a cross section.

The fastening protrusion 232 is inserted into the protrusion insertion groove 112 and the fastening groove 113 of the coupling portion 110 to be described later, and is formed to protrude in the radial direction from the outer circumferential surface of the insertion column 231. The fastening protrusions 232 are spaced along the outer circumferential surface of the insertion column 231 to be formed in plural, so that it is preferable to improve the bonding force between the dedicated jig 200 and the common jig 100.

The dedicated jig 200 as described above may be formed in a different shape according to the type of the housing 300 to be inspected. In more detail, as illustrated in FIG. 11, a housing seat having a different shape is formed in the dedicated jig 200 ′. That is, only the shape of the housing seating portion is changed according to the outer shape of the housing 300, and the clamp 220 and the fastening portion 230 are applied in the same way.

As such, by providing various types of dedicated jigs 200 and 200 'according to the outer shape of the housing 300, the housing 300 of various shapes can be inspected. That is, various types of housings 300 can be applied by changing and combining the dedicated jig 200 to one common jig 100, thereby increasing the utilization range of the inspection jig and reducing production cost.

The common jig 100 is to determine the insertion state of the terminal 400 coupled to the housing 300 by combining the dedicated jig 200 described above. 9 and 10, the joint jig 100 includes a coupling unit 110 and a detection unit 120, and a connection shaft 130 coupling the coupling unit 110 and the detection unit 120 Is provided. 10 is a cross-sectional view of the common jig 100, FIG. 10 (a) is a basic state in which no force is applied to the common jig 100, and FIG. 10 (b) is a common jig 200 In the process of coupling to (100), while the blocking plate 116 is pressed down to the lower side (inside of the coupling part 110), FIG. 10 (c) shows that the combination of the dedicated jig 200 and the common jig 100 When completed, the blocking plate 116 has returned to its original position, but the coupling part 110 is moved in a direction away from the detection part 120 during the inspection of the coupling state of the terminal 400.

Coupling unit 110, as the fastening unit 230 of the dedicated jig 200 is inserted and coupled, the insertion hole 111, the projection insertion groove 112, the fastening groove 113, the fixing groove 115 and Shaft seating groove 114 is formed, the blocking plate 116 is coupled.

The insertion hole 111 is inserted and coupled to the insertion column 231, and is formed by being recessed on one surface of the coupling portion 110. At this time, the insertion hole 111 is preferably formed in a circular cross section so that the insertion column 231 can be stably inserted.

The protrusion insertion groove 112 is a place where a plurality of fastening protrusions 232 are inserted, and is formed in the depth direction of the insertion hole 111 on the inner circumferential surface of the insertion hole 111. More specifically, the projection insertion groove 112 is formed spaced apart along the outer circumferential surface of the insertion hole 111 at the same interval as the plurality of fastening protrusions 232 are formed. At this time, the projection insertion groove 112 is formed in a groove shape from the inlet of the insertion hole 111 so that the fastening projection 232 can be inserted to the inside of the insertion hole 111 along the projection insertion groove (112).

The fastening groove 113 guides the fastening protrusion 232 inserted into the insertion hole 111 through the projection insertion groove 112 to move to the fixing groove 115, along the inner circumferential surface of the insertion hole 111. Is formed. More specifically, the fastening groove 113 is formed in a ring shape along the inner circumferential surface of the insertion hole 111 in communication with the projection insertion groove 112 at a position spaced a predetermined depth from the inlet of the insertion hole 111.

The fixing groove 115 communicates with the fastening groove 113 at a position spaced apart from the projection insertion groove 112 and is formed in the depth direction of the insertion hole 111. At this time, the fixing groove 115 is formed in a direction toward the inlet of the insertion hole 111 in the fastening groove 113, it is preferable that a plurality of fastening protrusions 232 are spaced at the same intervals formed and formed in a plurality Do.

The blocking plate 116 is coupled to be movable toward the insertion hole 111, as shown in FIGS. 10 (a) and 10 (b), inside the coupling portion 110, and the diameter of the fastening groove 113 It is preferably formed in the same way. The blocking plate 116 is coupled to the back surface of the surface exposed to the outside through the insertion hole 111 so that the pressing spring 116a is coupled to receive a force pushed toward the insertion hole 111, and the fastening groove 113 Is inserted.

As the fastening portion 230 is coupled to the coupling portion 110 formed as described above, the dedicated jig 200 and the common jig 100 are combined. In more detail, in order to combine the dedicated jig 200 and the common jig 100, the operator fits the plurality of fastening protrusions 232 to be inserted into the plurality of protrusion insertion grooves 112, and then inserts the pillar 231. Is inserted into the insertion hole 111. When the end of the insertion column 231 is in contact with the blocking plate 116, the dedicated jig 200 is pressed, as shown in FIG. 10 (b), so that the blocking plate 116 can be moved downward. Then, while pressing, the dedicated jig 200 is rotated to insert the fastening projection 232 into the fastening groove 113. When the fastening protrusion 232 enters the fastening groove 113, the dedicated jig 200 is continuously rotated until the fastening protrusion 232 enters the fixing groove 115. In this case, it is not necessary to press the dedicated jig 200. When the fastening protrusion 232 is inserted into the fixing groove 115, the engaging operation can be completed by pulling the dedicated jig 200 in the opposite direction of insertion to confirm whether the common jig 100 is properly engaged.

By constructing the coupling structure with such a simple configuration, it can be combined with a simple operation of insertion and rotation. Therefore, the operator can combine the dedicated jig 200 and the common jig 100 with intuitive judgment, thereby facilitating work.

The shaft seating groove 114 is a place where the connecting shaft 130 is inserted and seated, and is formed at a position spaced apart from the insertion hole 111. At this time, the shaft seating groove 114 is preferably formed equal to the number of connecting shaft 130. In addition, a locking jaw 114a is formed to protrude inward on the inner circumferential surface of the shaft seating groove 114. At this time, the locking jaw 114a is formed by a plurality of stages in the depth direction of the shaft seating groove 114, so that the locking protrusions 131 and the shaft springs 132 of the connecting shaft 130, which will be described later, are supported in contact with each other.

The detection unit 120 is coupled so that the coupling unit 110 is movable, and a detection switch 121 and an alarm unit 122 that detect movement of the coupling unit 110 are formed.

The detection switch 121 is switched to an ON state and an OFF state, and is coupled to the detection unit 120 to come into contact with the coupling unit 110. In more detail, the coupling part 110 coupled to the detection part 120 receives a force pulled toward the detection part 120 by the connecting shaft 130, as shown in FIG. 10 (a). Then, the detection switch 121 is pressed against the coupling portion 110 that is pulled toward the detection portion 120. And, as shown in Figure 10 (b), when the engaging portion 110 is pulled in a direction away from the detection unit 120, the detection switch 121 is not pressed. Here, in the detection switch 121, a pressed state is an OFF state, and an unpressed state is an ON state. Therefore, when the coupling unit 110 is moved in a direction away from the detection unit 120, it is switched from an OFF state to an ON state.

The alarm unit 122 initiates an alarm to an operator when the detection switch 121 is switched to an ON state, and may be implemented in various ways. When the detection switch 121 is turned on using a light emitting device such as an LED, light may be emitted to inform. Alternatively, an acoustic device may be used to notify the user by making a buzzer sound. The on / off state of the detection switch 121 can be initiated to the operator by using various other methods.

Power is applied to the above detection unit 120 to drive the detection switch 121 and the alarm unit 122.

As described above, by separately configuring the alarm unit 122, an operator can intuitively check whether the coupling unit 110 is moved, thereby facilitating work. In addition, by determining the combined test result of the terminal 400 according to whether the alarm unit 122 is alarmed, a plurality of workers can determine the same criteria, thereby improving the reliability of the test result.

The connecting shaft 130 is a combination of the coupling portion 110 and the detection portion 120, one side is inserted into the shaft seating groove 114 of the coupling portion 110, and the other side is fixed to the detection portion 120. That is, the connecting shaft 130 is coupled through the coupling portion 110 and the contact portion 120. And, at one end of the connecting shaft 130 that is inserted into the shaft seating groove 114, a locking protrusion 131 is formed. The locking protrusion 131 is formed to protrude in the radial direction at the end of the connecting shaft 130, and is formed to contact the locking jaw 114a.

As such, the shaft spring 132 is coupled to one side of the connecting shaft 130 on which the locking protrusion 131 is formed. The shaft spring 132 is coupled so that one end is in contact with the engaging protrusion 131 and the other end is in contact with the engaging jaw 114a. The coupled shaft spring 132 is to press the locking protrusion 131 and the locking jaw 114a in a direction away from each other, and the ends of the connecting shaft 130 are positioned on the upper side of the shaft mounting groove 114 based on the drawing. To be able to. That is, the coupling part 110 is fixed by pressing it toward the detection part 120.

At this time, the engaging protrusion 131 and the shaft spring 132 may be coupled to contact with the engaging jaw 114a formed by a plurality of stages, respectively.

By forming the shaft spring 132 on the connecting shaft 130, a force pulling toward the detection unit 120 is continuously applied to the coupling unit 110, and the coupling unit 110 presses the detection switch 121 to turn off ( OFF) to maintain the state. Therefore, when pulling the coupling portion 110 away from the detection unit 120 and then releasing it, the coupling portion 110 returns to the original position again.

Hereinafter, with reference to FIG. 12, the principle of inspecting the coupling state of the terminal 400 coupled to the housing 300 will be described. First, the bonding state of the terminal 400 coupled to the housing 300 is examined by pulling the wire 500 coupled to the terminal 400. When the terminal 400 is fully coupled to the housing 300, the terminal 400 will not be detached from the housing 300, and if it is incompletely coupled, the terminal 400 will be detached from the housing 300. Below, for convenience of description, the direction in which the wire 500 is pulled is referred to as a 'pull direction'.

First, when the terminal 400 is fully coupled, when the wire 500 coupled to the housing 300 is pulled in the pulling direction, the terminal 400 is moved in the pulling direction by the wire 500 and the terminal 400 The fully coupled housing 300 moves together. Similarly, the dedicated jig 200 coupled to the housing 300 and the engaging portion 110 coupled to the dedicated jig 200 move together in the pulling direction. When the coupling portion 110 is moved, as shown in FIG. 12 (b), the shaft spring 132 is compressed and the detection switch 121 is switched to the ON state.

That is, when the terminal 400 is fully coupled, the coupling force between the terminal 400 and the housing 300 is greater than the spring force by which the shaft spring 132 pulls the coupling unit 110 to the detection unit 120. Therefore, when the wire 500 is pulled, the coupling part 110 is moved together in the pulling direction.

On the other hand, when the terminal 400 is incompletely coupled, the wire 500 coupled to the terminal 400 is moved in the pulling direction, and a force to move in the pulling direction is also applied to the housing 300. However, since the shaft spring 132 presses the engaging portion 110 toward the detection unit 120, the dedicated jig 200 coupled to the engaging portion 110 also cannot move in the pulling direction, and is coupled to the dedicated jig 200 The housing 300 is also not moved in the pulling direction. Therefore, the housing 300 is not moved and the terminal 400 is removed from the housing 300.

That is, in the state where the terminal 400 is incompletely coupled, the coupling force between the terminal 400 and the housing 300 is smaller than the spring force by which the shaft spring 132 pulls the coupling portion 110 to the detection unit 120. Therefore, when the wire 500 is pulled, the coupling part 110, the dedicated jig 200 and the housing 300 do not move, and the terminal 400 is separated from the housing 300.

As described, the inspection jig of the present invention inspects the coupling state of the terminal 400 by applying a continuous force in a direction opposite to the pulling direction to the housing 300 to which the terminal 400 is coupled. At this time, the inspection jig of the present invention, by applying a constant force to the housing 300, it is possible to check the binding force of a certain size between the housing 300 and the terminal 400. Therefore, even if a plurality of workers perform the inspection of the coupling state of the terminal 400, it is possible to always obtain the same result. In addition, it is possible to accurately detect an incomplete coupling of the terminal 400 by ensuring a coupling force of a certain size or more between the terminal 400 and the housing 300, thereby improving the quality.

13 shows a procedure for performing a terminal state inspection of the terminal 400 using the inspection jig of the present invention.

To start the inspection, the operator is provided with a dedicated jig 200 suitable for the housing 300 to be inspected, and then combines the housing 300 with the dedicated jig 200. Then, the fastening protrusion 232 of the dedicated jig 200 is aligned with the protrusion insertion groove 112 of the common jig 100 and inserted. Thereafter, while pressing the blocking plate 116 downward, the dedicated jig 200 is rotated so that the fastening protrusion 232 moves to the fixing groove 115. When the fastening projection 232 is inserted into the fixing groove 115, confirm the combination of the dedicated jig 200 and the common jig 100 by pulling. When the combination of the dedicated jig 200 and the common jig 100 is completed, the terminal 400 to which the wire 500 is connected is inserted into the terminal insertion hole 310 of the housing 300 to be coupled. Then, the wire 500 is pulled in the pulling direction. At this time, the operator pulls the wire 500 to the alarm unit 122 until the alarm is started. If the terminal 400 is fully coupled, an alarm will be initiated to the alarm unit 122 as shown in FIG. 13 (f), and if incompletely coupled, the terminal 400 will be separated from the housing 300.

When an alarm is started in the alarm unit 122, it is determined that the terminal 400 is fully coupled, and the previous process is repeated to insert the next terminal. On the other hand, when the terminal 400 is separated from the housing 300, the terminal 400 is damaged or worn, and the terminal 400 is judged to be defective or replaced or inserted again into the terminal insertion hole 610 to repeat the process. do.

When using the inspection jig of the present invention, as described, it is possible to perform the inspection by pulling the wire 500 only as much as the force corresponding to the required binding force between the terminal 400 and the housing 300. In addition, when the binding force is satisfied, the alarm is immediately started to the alarm unit 122, so that there is no need to apply more force. Therefore, by minimizing the force that the operator uses in the inspection process, there is an effect that can reduce the fatigue of the operator.

In addition, since the inspection jig always pulls the housing 300 with the same force, the same result can be obtained even when a plurality of workers perform the inspection, thereby improving the reliability of the inspection result.

In addition, by allowing the terminal 400 to check whether the terminal 400 is engaged in the step of inserting the terminal 400 into the housing 300, the process can be efficiently operated. In addition, by improving the reliability of the inspection result, there is an effect of improving the quality by preventing the problem of defective bonding of the terminal 400 in the latter process or the finished product.

The above is merely a description of some of the preferred embodiments that can be implemented by the present invention, and as is well known, the scope of the present invention should not be construed as being limited to the above-described one embodiment. It will be said that the technical spirit of the invention and the technical spirit of the same are all included in the scope of the present invention.
