In the case of the devices shown in FIGS. 12 and 13, there is a problem that it takes time because a plurality of operations are required to install and operate the device. In addition, it takes the same amount of time to replace the device. It is possible to consolidate connectors to reduce work, but it is difficult to eliminate the function of connecting cables to each connector because some users want to access each connector without consolidating depending on the device. There was also a problem. Further, since a plurality of cables are fixed to the device, there is a problem in terms of appearance (landscape), and there is a problem that time and skill are required for cable bundling and the like. Further, as shown in FIG. 14, since the cable joint is exposed, it is necessary to take additional measures to prevent the cable from falling off or being tampered with. Generally, the method of fixing the cable with tape is adopted, but the load is applied to the operator when working at a high place. As a measure for appearance, there is a measure to add a member that hides the cable wiring, but there is a problem that it is necessary to separately prepare a member and separately consider a method for fixing the member. (Fig. 15)

(First Embodiment)
A first embodiment of the connector connection structure of the present invention is shown in FIGS. 1 to 6.

1A and 1B are perspective views showing a connector connection structure, FIG. 1A is a view showing the entire connector connection structure, FIG. 1B is a view showing an electronic device B having connectors A-1 to AN, and FIG. 1C is a view showing a connector A. It is a figure which shows the docking station C which is electrically connected with -1 to AN.

The electronic device B is connected to the docking station C with connectors A-1 to A-N (the number is arbitrary, and when N connectors are collectively referred to as the connector portion A). The individual connectors A-1 to A-N constituting the connector portion A may be ordinary connectors. In other words, ready-made products used for communication (modular plug jack, RS232-C, LAN terminal, etc.), computer (USB, IEEE1394, etc.), power supply connector, display connection connector, coaxial (BNC, etc.), optical connector, etc. Can be used.

FIG. 2 is a perspective view of the docking station C. The docking station C has connector receiving portions E-1 to E-N (the number is arbitrary, hereinafter collectively referred to as a connector relay portion E) that is electrically connected to each of the connectors A-1 to A-N. FIG. 2 shows two connector receiving portions E-K and E-K + 1. The individual connectors that make up the individual connector receivers can be used off-the-shelf or partially modified. If the connector A-1 is a male terminal, the connector terminal of the connector receiving portion E-1 that receives the connector is a female terminal that can be electrically connected by fitting with the male terminal. The number of connector receiving portions is the same as that of the connector portion A. The electronic device B and the connector receiving part are male and female to receive them, respectively. If the connector shape on the electronic device B side is male, the connector receiving part is female, and conversely, if the electronic device B side is female, the connector receiving part. The department is a male. If the connector part A is a mixture of male and female, the connector receiving part is a mixture of female and male corresponding to it.

The connector relay unit E is fixed to the case unit F to form the docking station C. The case portion F is a metal case having a U-shaped cross section, and the two side plates 201 and the bottom plate 203 form a U-shape, and the upper side, that is, the side connected to the connector portion A is opened. In FIG. 2, the portion hidden by the front side plate 201 is transparently shown.

Four springs 205 are provided on the outer walls of the individual connector receiving portions E-1 to E-N, and one spring 206 is provided on the bottom surface. In FIG. 2, all the springs 205 and 206 are displayed on the connector receiving portion E-K + 1, and only a part of the springs 205 and 206 are displayed on the connector receiving portion E-K. Actually, five springs are also provided in the connector receiving part E-K.

The springs 205 and 206 are provided on the outer walls of the individual connector receiving portions E-1 to E-N. A fixing portion 207 for fixing (hooking) one end of the spring is provided on the fixing plate 209. The fixing portion 207 is provided with a convex portion at a position where one end of the springs 205 and 206 is fixed, and a concave portion is provided in the convex portion. Further, a recess for fixing the other ends of the springs 205 and 206 is provided by carving the outer wall of the connector receiving portions E-1 to E-N. In this embodiment, both ends of the fixing plate 209 are connected to the side plate 201 of the case portion F, and the case portion F and the connector relay portion E are substantially integrated. Further, the height of the fixing plate 209 is lower than that of the side plate 201 to facilitate the work. Further, in order to put out the cables Hk and H-K + 1 in the direction of the bottom plate 203 and crawl on the bottom plate toward the aggregation portion G described later, the fixing plate 209 does not reach the bottom plate 203, and the cable H (plural). When the cables H-1 to HN are collectively referred to, the space d through which the cable H) passes is secured.

For individual connectors A-1 to AN, the connectors are squeezed or pushed in to bring the male and female terminals into contact with each other for electrical connection, so insert a hand or tool between the adjacent connectors to perform the connection work. An interval L1 for doing this is provided. FIG. 3 shows the interval L1 provided between the individual connectors A-1 to A-N. Since the interval L1 is a gap for inserting a hand or a tool to perform the connection work, it may be the same between the plurality of connector receiving portions and the connector portions A, but may be different. In the connector portion A, each of the connectors 301, 302, and 303 has a space S having a size L2 × L3, like the connector receiving portion. L1 is much larger than L2 and L3.

The dimension L2 between the two fixing plates 209 surrounding one connector receiving portion EK (K = 1 to N) and the dimension L3 between the two side plates of the case portion F are all the connector receiving portions E-1 to EN. Make it the same. That is, the shape and dimensions of the space S (first space) accommodating the connector receiving portions E-1 to E-N are all the same. The space is determined according to the size of the largest connector assumed as the connectors A-1 to A-N to be connected to the connector receiving part. In the case of FIG. 2, it is a rectangle of L2 × L3. This rectangle may be a square (L2 = L3) or a rectangle (L2 ≠ L3). Each connector receiving part is installed in the center of this fixed-shaped space. That is, the center of each connector receiving portion is aligned with the center of the space, and the connector portion A to be connected is aligned with the installation. On the other hand, each connector of the connector portion A has a second space having the same size as the first space for accommodating each connector receiving portion, and is installed in the center of the second space. That is, the center of each connector receiving portion is installed so as to coincide with the center of the space. In this way, the connector portion A composed of a plurality of connectors and the connector relay portion E can be connected at the same time. Due to the tolerance at the time of manufacture, the positions of the connector part A and the connector constituting the connector receiving part may be misaligned, but due to the above-mentioned spring, the connector receiving part moves within the tolerance range and connection is possible. Become.

FIG. 4 is a plan view of the docking station C of FIG. 2 as viewed from above. Only the connector receiving parts E-K and E-K + 1 are shown. Since the types of the two connector receiving portions are different, the distances (L4, L4') between the connector and the side plate and the connector and the fixing plate in the space S are different. Therefore, adjust the lengths of the springs 205 and 206 so that the connector is located in the center of the space S. Unless the shape of the space S and the shape of the connector receiving part are both square or circular, the four L4s (L4') in one connector receiving part will not be the same, but in FIG. 4, they are all the same notation L4. It is set to L4'.

Next, the cable H will be described. Thick cables require a large curvature to bend, and thin cables require a small curvature. Therefore, the distance between the bottom of the connector receiving portion and the bottom surface of the case portion F differs depending on the type of the connector receiving portion. Therefore, the spring used for the connector receiving part that requires a large curvature is tall, and the spring used for the connector receiving part that requires a small curvature is short. In addition to this, the lengths (heights) of the connector part A and the connector receiving parts E-1 to EN differ depending on the type, so the lengths of the connectors A-1 to AN as seen from the connector receiving parts E-1 to EN. (Height) is different. Therefore, adjust the height of the spring so that the heights of the connector receiving portions E-1 to E-N match the height of the connector portion A to ensure an electrical connection.

The connector relay section E is arranged in each space S so as to correspond to the position of the connector section A. The cable H is passed through the aggregation part G of the case part F. Mount Docking Station C on a wall or pole. After that, the packing D is sandwiched between them, and the connector portion A of the electronic device B is connected to the connector relay portion E.

Many types of connector part A are assumed. For example, the connector is threaded, and some are screwed into the connector connection multiple times to fix it, while others are pushed into the connector to connect. The structure and shape of the connector part A are the same as the existing ones. Therefore, when the docking station C is not used, the cable may be connected to the connector portion A by the usual method, and various user requests can be met.

Corresponding cables H-1 to H-N (any number) are fixed from each connector receiving portion, and the cables H are collectively exited from the centralizing portion G. Each cable H is independent, and when the corresponding connector receiving part is removed, the cable H also comes out. In FIG. 1, the centralized portion has a cylindrical shape (circular cross section), but when the number of cables is large, the cross section may be widened to form a shape like a truck on land. Further, the surface provided with the collecting portion G may be eliminated, and the surface may be opened to facilitate the work of pulling out the cable from the case portion F. Such an opening is also called an aggregation unit G.

The connector part A is assumed to be various, and the tightening method is different for each connector. In the present embodiment, it is difficult to screw in a connector of a type that is screwed in and fixed. Therefore, instead of being mechanically fixed, the connector relay portion E and the connector portion A are in electrical contact with each other to satisfy the electrical function. As shown in FIG. 10, for example, if the outer diameter of one connector 1000 is smaller than that of the other connector 1001, electrical connection is possible if the wires to be connected (center conductor 1002) come into contact with each other.

However, in the case of this method, since the screw thread 1004 is not screwed in, the waterproof property of the connector is impaired. Fill with packing D.
(Explanation of operation)
The connector relay portion E of the docking station C is arranged so as to correspond to the position of the connector portion A of the electronic device B. Specifically, prepare a type that can connect the connector receiving portions E-1 to EN to the opposing connectors A-1 to AN. Cables H-1 to HN are integrally connected to the connector receiving portions E-1 to EN on the opposite side of the connector portion A, respectively. First, fit the end of the spring of the bottom plate into the fixed part of the bottom plate, then insert the cable HK of one connector receiving part EK into the space in the center of the spring 206, and when the cable H passes through the spring 206, the case part Crawl on the bottom plate of F and pull out the other side of the cable from the central part G. If a spring with a large diameter, for example, one having the same diameter as the bottom of the connector relay part E, is used, it is easy to pass the cable. The cable is pulled out from between the spring 206 and the bottom plate of the case portion F toward the central portion G, but if the distance from the end of the spring 206 fitted to the bottom plate to the start of winding of the spring is long, the cable is pulled out. Cheap.

After that, the connector receiving portions E-1 to E-N connected to the cable are inserted between the side plates of the case portion F, and the ends of the four springs are fitted into the recesses of the side plates. This work is performed in the same manner for the remaining N-1 connector receiving portions. After that, the docking station C is attached to a wall or a pole as shown in FIG. 5 with a mounting bracket (not shown) provided on the opposite side of the collecting portion G of the case portion F.

Next, the electronic device B is fixed from above, but as shown in FIG. 6, the connection surface between the electronic device B and the docking station C is aligned with the rectangular ring-shaped packing D sandwiched between them to ensure airtightness. , Thoroughly crush packing D and fix it. Screws, hooks, etc. are provided on the electronic device B and the docking station C (not shown), and they are sufficiently fixed to each other. At the same time as this fixing work is completed, the connection between the connector portion A and the connector relay portion E of the electronic device B is also completed.

As described above, each connector receiving portion can be moved by a spring. Therefore, when the weight of the electronic device B is applied to the docking station C during the fixing work, it can be moved to the position where the male and female terminals of the connector relay portion E and the connector portion A fit, and the electrical connection between a plurality of connectors can be easily performed. You can take it. Various types of connectors are used for the connector part A. However, in the present embodiment, the spaces for accommodating one connector receiving portion E-K all have the same shape. That is, the vertical and horizontal sizes of the spaces are the same, so when viewed from above, the case portion F is divided into the same shape by a fixed plate. As a result, even if various combinations of the individual connectors A-1 to A-N constituting the connector portion A are exchanged, the connector can be connected to the connector relay portion E.

A structure that secures a space (L1 described above) between connectors when the connector is squeezed by hand is common, and the difference depending on the type of connector (difference between L4 and L4'is small) is 10 mm compared to the space. It is as follows.

If it is a small connector, the moving distance required to connect to the connector part A is also small, so if the size of the space S is optimally set according to the size and shape of each connector receiving part, the connector relay part E The length can be reduced. However, in that case, it is necessary to reset the space S every time the type of the connector portion A changes. That is, it is necessary to change the place where each connector receiving portion is fixed for each type of the connector portion A, which is very complicated. On the other hand, if the space S is matched to the largest connector used in the connector portion A as in the present embodiment, it is not necessary to change the space S even if the connector used in the connector portion A changes. , Versatile.
(Explanation of effect)
In the present embodiment, by consolidating the connector receiving portions in the docking station and making them movable, cables of various connection methods can be connected at once. Therefore, the time required for installing or replacing the device can be shortened, and the installation becomes easy.

In addition, since the cables can be aggregated, no external appearance measures are required, and each connector can be easily accessed by removing the electronic device from the docking station. Further, since the electronic device can be easily installed, no load is applied even when working at a high place.

Depending on the cost and customer's request, there may be a case where the existing structure in which the cable is individually connected to each connector is not desired to be changed. Since the present embodiment does not change the dimensions and shapes of the individual connectors A-1 to AN constituting the connector portion A, each of the connector portions A even when the connector receiving portion connection structure of the present embodiment is not used. Cables can be individually connected to the connector.
(Second embodiment)
7A and 7B are views showing the connector connection structure of the second embodiment of the present invention, in which FIG. 7A is a top view and FIG. 7B is a side view. This embodiment differs from the first embodiment in that a shoulder bolt 701 is used to fix the connector receiving portion EK to the case portion F. As the connector part that constitutes the connector receiving part, an off-the-shelf product or a modified part thereof can be used. In this embodiment, the fixing plate of the first embodiment is unnecessary.

Make two holes in the diagonal corner of the connector receiving part E-K body to pass the shoulder bolt 701. Pass the shoulder bolt through the two holes. Further, the screw at the tip of the shoulder bolt is screwed into the screw hole of the seat plate 702 to which the spring 706 is fixed, and the seat plate 702 is further fixed to the bottom plate 203 of the case portion F. Can be moved in the horizontal direction with the bottom plate 203 by the amount of the gap between the shoulder bolt 701 and the two holes 704 through which the shoulder bolt 701 is passed. Further, in the direction perpendicular to the bottom plate 203, the spring 706 can be moved by the amount of expansion and contraction.

Also, since the length (height) of the connector part A and the connector receiving parts E-1 to EN differs depending on the type, the length (height) of the connectors A-1 to AN as seen from the connector receiving parts E-1 to EN. Is different. Therefore, the height of the spring of the seat plate 702 is adjusted so that the heights of the connector receiving portions E-1 to E-N match the height of the connector portion A.

In addition, some other members are opened in the bottom plate of the case portion F in addition to these two holes so that different types of connector receiving portions can be accommodated.

Further, the cable H is connected to the connector relay portion E through the centralized portion of the case portion F, and the shoulder bolt of the connector relay portion E is screwed into the screw hole of the case portion F to fix it. Mount Docking Station C on a wall or pole. After that, the packing D is sandwiched between them, and the connector portion A of the electronic device B is connected to the connector relay portion E.

Further, since the connector constituting the connector receiving portion can generally absorb the tolerance in the height direction, the spring property becomes unnecessary as long as it is within the range.
