Description

  The present invention relates to a connector packing structure and a connector packing method.

  2. Description of the Related Art Conventionally, as described in Patent Document 1, a connector composed of two parts including a housing that accommodates a connection terminal and a holder that is engaged with the housing includes the two parts (housing and holder) together as a bag. And packed in boxes.

  That is, as shown in FIG. 6, the connector 1 to be packaged conventionally comprises a resin housing 1a capable of accommodating the connection terminals T and a resin holder 1b engaged with the housing 1a. It is. In addition, let the direction (arrow X direction of FIG. 1) which inserts the connecting terminal T in the connector 1 be the front.

  As shown in FIG. 6 (a), in the connector 1, a locking lance 1c for preventing terminal removal formed on the holder 1b side can be elastically deformed in the vertical direction (arrow Y direction in FIG. 1) within the housing 1a. At this position, the housing 1a and the holder 1b are locked by a temporary engaging portion (not shown), and are temporarily locked.

  Further, as shown in FIG. 6B, when the holder 1b is further pushed forward by the force F from the rear, the temporary engagement is released, and the locking lance 1c can come into contact with the base 1d in the housing 1a. At this position, the housing 1a and the holder 1b are brought into a final locking state in which they are locked by a main engagement portion (not shown). In this fully locked state, the locking lance 1c contacts the pedestal 1d in the housing 1a and is restricted from moving forward and swinging downward.

  That is, as shown in FIG. 7A, when the connection terminal T is inserted into the temporarily locked connector 1, the connection terminal 1a gets over the locking lance 1c and reaches the front side inside the housing 1a. Although not shown in the figure, when the holder 1b is further pushed in to bring the connector 1 into the final locking state, the locking protrusion 1e of the locking lance 1c comes into contact with the locking portion Ta of the connection terminal T, The connection terminal T is prevented from coming out backward. The connection terminal T is appropriately accommodated in a predetermined position in the housing 1a.

  However, as shown in FIG. 7B, when the connection terminal T is inserted into the connector 1 in the final locking state in which the connection terminal T is not accommodated, the swing of the locking lance 1c is restricted by the base 1d. Therefore, the connection terminal T cannot get over the locking lance 1c and cannot be accommodated in the housing 1a.

It is desired that the connector 1 as described above be packaged so as to reach the user in a temporarily locked state that can be said to be a state immediately before use. Further, in order to prevent breakage or deformation (particularly deformation or breakage of the locking lance 1c) due to contact between two parts having different shapes, packaging in a temporarily locked state is desirable.
In addition, even if it is possible to return from the final locking state to the temporary locking state (return operation) by performing a predetermined operation, the user may misuse the connection terminal T which is impossible in the final locking state. In order to prevent damage due to insertion or unreasonable return operation), it is desired to be packed in a temporarily locked state.

However, conventionally, as shown in FIG. 8, a plate-like partition member d is installed in a box D such as a cardboard for transportation, and a group of connectors having a predetermined weight are stored in a bag S and packed. Met. In such a conventional packing method, a large space is formed inside the bag body S or inside the box body D, and damage or deformation caused by contact between the connectors 1 due to vibration during transportation or impact of dropping, etc. Therefore, there is a possibility that a problem of erroneous insertion from the temporarily locked state to the fully locked state may occur.
JP-A-8-321344

  As described above, when packed in large quantities in bags or boxes, parts with different shapes (housing and holder) are strongly pressed (collised) with each other due to vibration during transportation or impact from dropping, resulting in damage or deformation. There was a problem that occurred.

  Further, when the holder is placed in the above-mentioned temporarily locked state and packed in a bag or a box as shown in FIG. 8, the housing is further pushed from the temporarily locked state and engaged before the connection terminal is inserted. Thus, there is a problem that erroneous insertion into the final locking state occurs, and the user arrives at the user (customer) in a state where the connection terminal cannot be inserted (the connector cannot be used).

Therefore, an object of the present invention is to provide a packaging structure and a connector packaging method that are less likely to cause problems such as breakage and deformation due to strong pressing between connectors.
In particular, when a connector in a temporarily locked state is packaged, another object is to prevent the occurrence of an erroneous insertion that unintentionally enters a fully locked state.

  In order to achieve the above object, a connector packaging structure according to the present invention is a connector packaging structure for packaging a plurality of connectors each including a housing that accommodates a connection terminal and a holder that engages with the housing. The connector is held in close contact with the vacuum sealed bag in a one-step planar alignment state.

  A connector packaging structure is provided for packaging a plurality of connectors each including a housing for accommodating a connection terminal and a holder engaged with the housing, wherein the holder (1b) is temporarily engaged with the housing. The above-mentioned connector in the locked state is arranged in the vacuum sealed bag in the vertical direction and the horizontal direction, and is tightly held in a one-step planar alignment state.

  Further, the connector packing method of the present invention is a connector packing method for packing a plurality of connectors each including a housing for accommodating connection terminals and a holder engaged with the housing, and the plurality of connectors to be packed. In a temporarily locked state in which the holder is temporarily engaged with the housing, and the connectors are stored in a one-step planar alignment state in the storage bag in the vertical and horizontal directions, and then the storage bag. Is vacuum-sealed, and the opening is fused to form a vacuum-sealed bag, and the plurality of connectors are closely held in the vacuum-sealed bag in a one-step planar alignment state and packed.

  Also, a connector packing method for packing a plurality of connectors including a housing for storing connection terminals and a holder for engaging with the housing, wherein the connector placement instruction diagram is drawn on the storage bag. Insert a sheet-like underlay material, put the plurality of connectors to be packed into a temporarily locked state in which the holder is temporarily engaged with the housing, and place the connector on the underlay material according to the arrangement instruction diagram. Next, they are stored in a one-step planar alignment state in the vertical and horizontal directions, then the underlay material is pulled out, the storage bag is evacuated, and the opening is fused to form a vacuum sealed bag. The plurality of connectors are packed in the vacuum sealed bag so as to be tightly held in a one-step planar alignment state.

The connector of the present invention can be neatly held in a one-step planar alignment state. The connector can be kept in close contact with a vacuum seal to prevent the connector from moving from the aligned state, and the connector can be prevented from being damaged or deformed by vibration or dropping during transportation. The connectors can be stored in a stacked manner in a transport box or the like with the connectors arranged in a single plane. It is possible to maintain the alignment state without using a tape or the like that causes the adhesive component to adhere to the connector and without contaminating the connector.
In particular, when packing a connector in a temporarily locked state, it is possible to prevent an erroneous insertion from the temporarily locked state to the fully locked state unintentionally due to strong pressing (collision) between the connectors and a drop impact. .

Hereinafter, a connector packing structure and a connector packing method of the present invention will be described in detail based on the drawings showing the embodiments.
First, the connector packaging method according to the embodiment of the present invention includes two parts (housing 1a and holder) as described above, as shown in a sectional side view shown in FIG. 1 (a) and a sectional plan view shown in FIG. 1 (b). The known connector 1 configured in 1b) is temporarily locked.

  Next, a sheet-like underlay material 20 on which an arrangement instruction diagram 20a of the connector 1 to be stored is drawn is inserted into a storage bag 10A formed by laminating a thermoplastic resin such as polyethylene or polypropylene. In accordance with the instruction of the arrangement instruction figure 20a shown by the alternate long and short dash line, the connector 1 temporarily locked in the longitudinal (front-rear) direction (arrow V direction) and the lateral (left-right) direction (arrow W direction) is placed on the underlying material 20 A predetermined quantity is arranged. Further, the adjacent connectors 1 and 1 in the vertical direction and the horizontal direction are arranged in contact with each other.

  The arrangement instruction figure 20a shows a predetermined position where the connector 1 is to be arranged, a predetermined attitude (front-rear direction, left-right direction, front-back direction) and quantity of the connector 1. The postures of the plurality of connectors 1 are unified on the underlay material 20 in the storage bag 10A and arranged in a one-step planar alignment state. In other words, the connectors 1 are arranged in a grid shape (a grid pattern) whose number can be easily confirmed. In addition, although the arrangement | positioning instruction | indication figure 20a was shown by the dashed-dotted line in FIG. 1, it is actually made into the drawing, photograph, etc. which have the character and figure (visible).

  Next, as shown in FIG. 2, after arranging the connector 1, the underlay material 20 is pulled out from the storage bag 10A. In the storage bag 10A, the plurality of connectors 1 arranged in the vertical direction and the horizontal direction and maintained in the one-step planar alignment state are left.

  Then, as shown in FIG. 3, the nozzle 50a of the suction device 50 is inserted from the opening of the storage bag 10A where the plurality of connectors 1 remain, and the air in the storage bag 10A is sucked (evacuated). The storage bag 10A is brought into close contact with the shape (unevenness) of the connector by the internal negative pressure.

After evacuation, the fusion bag 50b attached to the suction device 50 is used to fuse the opening to seal the storage bag 10A to form the vacuum sealed bag 10. The plurality of connectors 1 are packed and held together in a one-step planar alignment state with the adhesion force due to the negative pressure.
As shown in FIGS. 4 (a) and 4 (b), the plurality of connectors 1 in a temporarily locked state are aligned in the vertical and horizontal directions in the vacuum sealing bag 10 to be in a one-step planar alignment state (FIG. 4 (a). ), The connector packaging body 30 (first packaging state) is formed in which the atmospheric pressure P is applied and held tightly from the outside.

  And as shown in FIG. 5, the direction (arrow X direction) in which the holder 1b is inserted in the box D for shipping or storing such as a cardboard box is connected to the plurality of connector packing bodies 30 in the box D. It arrange | positions in the laminated form so that it may become horizontal with respect to a bottom face, and also packs (2nd packing state), and the packaging of the connector 1 is complete | finished.

The connector package 30 is obtained by the packaging method described above.
That is, in the connector packing structure of the embodiment of the present invention, as shown in FIG. 4, a plurality of temporarily locked connectors 1 are arranged in a vertical and horizontal direction in a vacuum sealing bag 10 and aligned in a single plane. It is a structure that is kept in close contact with the state.
The vacuum-sealed bag 10 pulls the connector 1 inward (of the vacuum-sealed bag 10) by the negative pressure inside. That is, as shown in FIG. 4A, the atmospheric pressure P acts from the outside, and the inner surface of the bag 10 is in close contact with the outer surface of the connector 1. The adjacent connectors 1 and 1 in the vertical direction and the horizontal direction are in close contact with each other with an appropriate force (a force that does not cause the connector 1 to be fully locked, or a force that does not cause deformation or damage). Is in surface contact. It can be said that the movement in the vertical (front-rear) direction (arrow V direction) and the horizontal direction (arrow W direction) is restricted and formed as one flat block body member.

  The vacuum-sealed bag 10 is a storage bag 10A that is evacuated and whose opening is sealed, and the thickness of the storage bag 10A is preferably 0.04 mm to 0.08 mm. If the thickness is less than 0.04 mm, the connector 1 may be in close contact with the connector 1 or may be damaged (breached) by an external force. If the thickness is greater than 0.08 mm, the connector is used when evacuated (becomes a vacuum sealed bag 10). This is because it is difficult to keep in close contact with the unevenness of 1.

The effect | action of the connector packing structure of embodiment mentioned above is demonstrated.
In a state where the connectors 1 and 1 are not in contact with each other before being evacuated, a part of the vacuum sealing bag 10 enters and prevents the connector 1 from moving into the space. Further, when the vacuum sealing bag 10 is brought into close contact with the concavity and convexity of the connector 1, the connector 1 and the vacuum sealing bag 10 are engaged with each other, and the movement of the connector 1 is restricted. Prevents connectors 1 and 1 from moving and coming into contact with each other due to vibrations during transportation or impact from falling, causing damage or deformation, incorrect insertion (unintentionally changing from temporarily locked to fully locked), etc. The occurrence of problems is prevented. Moreover, it can be said that it is a flat block shape, and can be stood like a book and can be stored and temporarily placed.

  In particular, when a plurality of connector packaging bodies 30 having the connector structure of the embodiment are packaged in the box body D, they can be stacked while being brought into surface contact in a stacked manner. That is, the connector 1 can be packed in the box D by being aligned in the vertical and horizontal directions, and further in the vertical direction (the direction indicated by the arrow H in FIG. 5). Compared to the conventional example (see FIG. 8), a useless space is not formed, and the bulk density (the number of storage) is improved.

  Next, a comparison verification between the conventional example of FIG. 8 and the example shown in FIG. 5 was actually performed on the box D having the same size. First, in the conventional example in which the packaged connector 1 is stored in the box D divided by the partition member d, the number of connectors 1 stored (packed) is 500. In the embodiment of FIG. 5 in which a plurality of connector packages 30 are laminated, the number is 1008. In addition, when the verification was performed using another connector having a different shape, a result that enables 2.77 times the quantity of packaging was obtained. That is, although depending on the outer shape, a result that enables packing of about 1.5 to 2.8 times the quantity of the conventional example was obtained.

Further, the above-described conventional example containing 500 pieces and the example containing 1008 pieces were dropped from a height of 1 m five times for comparative verification.
In the conventional example, 6 defective products such as breakage and incorrect insertion occurred. In the examples, there was no defective product although the quantity (weight) was 1.5 times or more. Thus, it can be seen that the occurrence of defects has been remarkably reduced.

  Further, since the connector 1 is packed in the vacuum sealed bag 10 in a predetermined quantity and already sorted (separated) into the predetermined quantity, the partition of the box D as in the conventional example shown in FIG. The installation work of the member d can be omitted. In addition, the quantity control by weight can be easily performed from the confirmation of the number by weight.

  In the present invention, the design can be changed. For example, in FIG. 1B, the arrangement instruction diagram 20a is oriented in the same direction as the connector 1, but depending on the outer shape of the connector 1, May instruct the connector 1 to face in a different direction or front and back so that the storage area becomes smaller.

  Further, when the connector package 30 is packaged (stored) in the box D, the direction in which the holder 1b is inserted (arrow X direction) is arranged so as to be perpendicular to the bottom surface of the box D ( Storage).

The suction device 50 preferably has an intake performance of −66.7 ± 10 kPa. The inspiratory time is preferably 1 to 10 seconds, more preferably 4 to 7 seconds.
For example, with a suction device 50 with an intake performance of −66.7 kPa, if the intake time (evacuation time) is shorter than 1 second, the vacuum sealing bag 10 is not sufficiently adhered to the connector 1 and is being transported. In addition, the connector 1 moves through the vacuum sealing bag 10 to increase the possibility of breakage, deformation, and erroneous insertion. On the other hand, if it is longer than 10 seconds, the force drawn toward the inside of the vacuum sealing bag 10 becomes strong, and the connector 1 may be damaged, deformed, or erroneously inserted.
In addition to the rear holder type connector 1 in which the holder 1b is fitted (engaged) from the rear of the housing 1a as described above, the connector 1 is not shown, but the front in which the holder 1b is fitted from the front of the housing 1a. The holder-type connector 1 and the side holder-type connector 1 into which the holder 1b is fitted can be freely used from either the top, bottom, left, or right lateral direction of the housing 1a.

  As described above, the present invention is a connector packing structure for packing a plurality of connectors 1 each including the housing 1a that accommodates the connection terminals T and the holder 1b that engages with the housing 1a. 1 is kept in close contact with the vacuum sealed bag 10 in a one-step planar arrangement, so that the connectors 1 and 1 are not strongly pressed (collised) with each other due to vibration during transportation or impact of dropping, The possibility of occurrence of defects such as breakage and deformation can be reduced. Further, it is possible to prevent the connector 1 from getting wet due to rain or the like, and adhesion of dust or the like. The connector 1 can be stored in the box D or the like in an aligned state, and the storage density (bulk density) can be improved. It can be packed (shipped) in large quantities compared to the conventional case, and transportation costs can be reduced.

  The connector packaging structure includes a plurality of connectors 1 each including a housing 1a that accommodates the connection terminals T and a holder 1b that engages with the housing 1a, and the holder 1b is temporarily engaged with the housing 1a. Since the above-mentioned connectors 1 in the temporarily locked state are aligned in the vertical and horizontal directions in the vacuum sealing bag 10 and held in close contact with each other in a one-step plane alignment state, each connector is affected by vibration during transportation or impact of dropping. 1 and 1 can be prevented from strongly pressing (collision) with each other, and the possibility of occurrence of problems such as breakage and deformation can be reduced. Further, it is possible to prevent the connector 1 from getting wet due to rain or the like, and adhesion of dust or the like. The connector 1 can be stored in the box D or the like in an aligned state, and the storage density (bulk density) can be improved. It can be packed (shipped) in large quantities compared to the past. Transportation costs can be reduced. Further, it is possible to prevent the main locking state (occurrence of erroneous insertion). In addition, misuse of the user (forcible insertion of the connection terminal T in the fully locked state or damage due to an excessive return operation) can be prevented in advance. The storage posture according to the situation such as stacking and leaning becomes possible, and the efficiency of the packing work is improved.

The holder 1b is temporarily engaged with 1a, and the connector 1 is stored in the storage bag 10A in the vertical and horizontal directions and stored in a one-step planar alignment state, and then the storage bag 10A is evacuated. Then, the vacuum sealing bag 10 is formed by fusing the openings, and the plurality of connectors 1 are packed and held in the vacuum sealing bag 10 in a one-step planar alignment state. The close contact holding force by the atmospheric pressure P acting on the bag 10 from the outside can prevent the connectors 1 and 1 from being strongly pressed (collised) with each other during transportation. The possibility of occurrence of problems such as breakage, deformation, and incorrect insertion can be reduced. In other words, the connector 1 is held in close contact with the vacuum-sealed bag 10 in a one-step planar alignment state, and the risk of problems occurring in the internal connector 1 during transportation is reduced. Further, it is possible to prevent the connector 1 from getting wet due to rain or the like, and adhesion of dust or the like. The quantity of the connector 1 can be easily managed. You can know the quantity of packing instantly. The connector 1 can be stored in the box D or the like in an aligned state, and the storage density (bulk density) can be improved.
