Description

Connector assembly and disassembly device{APPARATUS FOR ASSEMBLING AND DISASSEMBLING CONNECTOR}

The following description relates to a connector assembly and disassembly device.

In the case of developing a guided weapon system, it is common to manufacture and operate the system components by function, and then integrate them. Each component is electrically interconnected through connectors and cables based on a defined interface for receiving power or transmitting and receiving data. D-Sub connectors are assembled in a pin-socket method, and there are fasteners at both ends to maintain the connection state. If necessary, apply an anti-loosening agent to the fasteners or apply an appropriate tightening torque to stably maintain the assembly of the connector from external vibration and impact environments. In order to assemble/disassemble such a connector, a procedure of alternately tightening or loosening the fasteners at both ends is necessary.

When assembling/disassembling a connector, if only one fastener is excessively tightened or loosened, the connector tilts in one direction and the pins/sockets and fasteners may be damaged. If the pin/socket is damaged, the connector will have a problem in the electrical connection function, which can cause a great loss in the operation of the entire guided weapon system.

1 is a view showing the internal structure of a connector assembly and disassembly device according to an embodiment.

Referring to FIG. 1, the connector assembly and disassembly device 1 can stably assemble or disassemble the connector even when the space in which the components inside the housing of the miniaturized device are arranged is narrow. The connector assembly and disassembly device 1 may include a housing 11, an operation part 13, a rotation transmission part 12, a first fastening part 14 and a second fastening part 15.

The operation unit 13 may rotate by receiving a rotational force from the outside. For example, the operation part 13 may pass through the housing 11 and be disposed across the outside and the inside of the connector assembly and disassembly device 1. According to this structure, the operation unit 13 may transmit the rotational force transmitted from the outside to the inside of the connector assembly and disassembly device 1. The operation unit 13 may include a handle 131, a handling shaft 132, and handling gears 133 and 134.

The handle 131 may allow the user to rotate the operation unit 13. For example, the handle 131 may be disposed outside the housing 11. The user may rotate the operation part 13 by using the handle 131 or may slide a part of the operation part 13 against the housing 11 by pushing or pulling it.

The handling shaft 132 is integrally connected to the handle 131 and can rotate together. For example, when the handle 131 is rotated by an external force, the handling shaft 132 may rotate at the same angular speed as the handle 131. The handling shaft 132 may include a plurality of stoppers 1321 and 1322.

The plurality of stoppers 1321 and 1322 may limit the length of the operation part 13 inserted into the interior of the housing 11 and/or the length to be withdrawn. According to the plurality of stoppers 1321 and 1322, gears corresponding to each other can be meshed at an accurate position simply by sliding the operation unit 13 in one direction.

The first stopper 1321 may limit the length of the operation part 13 inserted into the housing 11. The second stopper 1322 may limit the length of the operation part 13 withdrawn from the inside of the housing 11. A description of the first stopper 1321 and the second stopper 1322 will be described in detail in the description of FIG. 5.

The handling gears 133 and 134 are integrally connected to the handling shaft 132 to rotate together. The handling gears 133 and 134 may directly contact the rotation transmission unit 12 to transmit rotational force generated by an external force. The handling gears 133 and 134 may include a low speed drive gear 133 and a high speed drive gear 134 having a diameter larger than that of the low speed drive gear 133.

The rotation transmission unit 12 may rotate by receiving the rotational force of the operation unit 13. The rotation transmission unit 12 may rotate in parallel with the rotation axis of the operation unit 13. The rotation transmission unit 12 may include rotation transmission gears 123 and 124, a rotation transmission shaft 122, and a worm gear 121.

The rotation transmission gears 123 and 124 may rotate by engaging with the handling gears 133 and 134. For example, the rotation transmission gears 123 and 124 may include a low speed driven gear 123 meshing with the low speed drive gear 133 and a high speed driven gear 124 meshing with the high speed drive gear 134. have. For example, the diameter of the high speed driven gear 124 may be smaller than the low speed driven gear 123. For example, the sum of the diameters of the high-speed drive gear 134 and the high-speed driven gear 124 may be equal to the sum of the diameters of the low-speed drive gear 133 and the low-speed driven gear 123. For example, the diameter of the high speed drive gear 134 may be the same as the diameter of the low speed driven gear 123.

The torque ratio of the high speed driven gear 124 to the high speed drive gear 134 may be smaller than the torque ratio of the low speed driven gear 123 to the low speed drive gear 133. According to this structure, first, in a state in which the high-speed drive gear 134 and the high-speed driven gear 124 are engaged, the worm gear 121 can rotate at a relatively high rotational speed. Fastening is possible. On the other hand, in a state in which the low-speed drive gear 133 and the low-speed driven gear 123 are engaged, the worm gear 121 can output a relatively high torque, so that the connector can be firmly fastened using a higher torque. . In other words, the connector assembly and disassembly device 1 has a structure in which the torque ratio of the rotation transmission unit 12 to the operation unit 13 can be adjusted, so that the torque ratio appropriate to the situation is selected, and the assembly and disassembly work of the connector It is possible to do.

The rotation transmission shaft 122 may be integrally connected with the rotation transmission gears 123 and 124 to rotate together, and the worm gear 121 may be integrally connected with the rotation transmission shaft 122 to rotate together.

The first fastening part 14 and the second fastening part 15 are parallel, and can rotate together by meshing with the rotation transmission part 12. The first fastening part 14 and the second fastening part 15 can tighten or loosen the two screws of the connector at the same time, so that even a miniaturized device can be precisely assembled. In addition, since the first fastening part 14 and the second fastening part 15 operate at the same time, it is possible to protect the durability of the equipment by preventing fatigue breakage or twisting due to imbalance of the fastening force. On the other hand, at least one of the first fastening portion 14 and the second fastening portion 15, at least one fastening portion may be provided with tips 143 and 153 that are positioned at an end and engageable with a screw and detachable. The tips 143 and 153 will be described in detail later in FIGS. 3, 4, and 7. The first fastening portion 14 includes a first assembly gear 141 and a first rotation transmission shaft 142, and the second fastening portion 15 is a second assembly gear 151 and a second rotation transmission It may include a shaft 152.

The assembly gears 141 and 151 may mesh with the worm gear 121. For example, the assembly gears 141 and 151 may be worm wheels, and the relative angles of meshing with the worm gear 121 may vary. According to this structure, the rotation axis of the worm gear 121 and the rotation axis of the assembly gears 141 and 151 may not be parallel. For example, as shown in FIG. 1 and the like, the rotation axis of the assembly gears 141 and 151 may be disposed perpendicular to the rotation axis of the worm gear 121.

The rotation transmission shafts 142 and 152 may be connected to the assembly gears 141 and 151 to convert and transmit the rotation direction of the worm gear 121. For example, the rotation axis of the operation unit 13, the rotation axis of the first fastening unit 14 and the rotation axis of the second fastening unit 15 may not be parallel. As shown in FIG. 1, the rotation axis of the operation part 13 and the rotation axis of the first fastening part 14 and the second fastening part 15 may be perpendicular to each other. According to this structure, even if the operation part 13 does not necessarily rotate in a position parallel to the rotation axis of the first fastening part 14 and the second fastening part 15, the first fastening part 14 and the second fastening part (15) can be rotated. Accordingly, when assembling the connector located between the narrow gap, the first fastening part 14 and the second fastening part 15 are rotated to assemble the connector even if the space is not secured as much as the length of the rotation axis of the operation part 13. And can be disassembled.

2 is a side view of an apparatus for assembling and disassembling a connector according to an exemplary embodiment.

1 and 2, a space 111 for adjusting a distance between a first fastening part 14 (see FIG. 1) and a second fastening part 15 (see FIG. 1) may be formed on the rear surface of the housing 11. have. The spacing adjustment space 111 is formed to be long along the length direction of the worm gear 121 (see FIG. 1), and fixes the relative positions of the first fastening part 14 and the second fastening part 15 according to the number of connector pins. The fixing groove 112 may be formed to be able to. The diameters of the rotation transmission shafts 142 and 152 may be smaller than the diameter of the fixing groove 112 and may be slightly larger than the height of the spacing adjustment space 111. In addition, the periphery of the spacing control space 111 of the housing 11 may be formed of a material having appropriate flexibility, such as rubber, silicone, plastic, or rubber. According to such a structure, the rotation transmission shafts 142 and 152 can be rotated while being mounted in the fixing groove 112, and may be moved along the spacing adjustment space 111 by a user's manipulation. 2 is a first tip 143 of the first fastening part 14 and the second tip 153 of the second fastening part 15 in the fixing groove 112, which can be applied to a connector having a 25-pin standard. It shows examples arranged at intervals.

FIG. 3 is a partially enlarged view of FIG. 1A, and FIG. 4 is a cross-sectional view taken along the line I-I of FIG. 3.

3 and 4, the rotation transmission shaft 142 and the tip 143 may be fitted with each other. The rotation transmission shaft 142 and the tip 143 may be coupled at at least two or more different angles. According to this structure, even when the angles of the screws installed on both sides of the connector are different from each other, by adjusting the angle of the tip 143 with respect to the rotation transmission shaft 142, it is possible to properly engage.

For example, the rotation transmission shaft 142 includes fine adjustment grooves 1421 (refer to FIG. 7) extending at different angles with respect to the central axis, and the tip 143 is a fine adjustment groove 1421 accommodated in the fine adjustment groove 1421. It may include an adjustment protrusion (1431 (see FIG. 7)). The fine adjustment groove 1421 and the fine adjustment protrusion 1431 may be molded and fixed so that they cannot rotate with respect to each other in a fitted state.

5 is a diagram illustrating a process of operating a connector assembly and disassembly device according to an exemplary embodiment.

Referring to FIG. 5, the operation part 13 may be inserted into the housing 11 or may be withdrawn from the inside of the housing 11 along the direction of the rotation axis of the operation part 13. According to the insertion and extraction of the operation unit 13, the torque ratio of the rotation transmission unit 12 to the operation unit 13 may be adjusted.

For example, when the handle 131 is pushed toward the housing 11, the first stopper 1321 contacts the housing 11 so that the operation part 13 is no longer inserted into the housing 11, and is driven at high speed. The gear 134 is engaged with the high-speed driven gear 124, so that the connector assembly and disassembly device 1 can operate in a high-speed mode. For example, in the initial stage of assembly of the connector or the final stage of disassembly of the connector, two screws can be fastened or loosened at the same time by using the above high-speed mode.

Conversely, when the handle 131 is pulled out of the housing 11, the second stopper 1322 contacts the housing 11, so that the operation part 13 is no longer pulled out of the housing 11, and the low-speed drive gear Since 133 is engaged with the low-speed driven gear 123, the connector assembly and disassembly device 1 can operate in a high torque mode. For example, in the final stage of assembly of the connector or the initial stage of disassembly of the connector, two screws can be tightened or loosened simultaneously with high torque by using the above high torque mode.

On the other hand, by varying the arrangement of each gear (123, 124, 133, 134), it is naturally possible to enter the high torque mode when the handle 131 is pushed in, and the high-speed mode when the handle 131 is pulled out. , A detailed description thereof will be omitted.

6 is a diagram illustrating a distance between a first fastening part and a second fastening part according to an exemplary embodiment.

For example, along the spacing control space 111, at least one of the first fastening part 14 and the second fastening part 15 is moved with respect to the worm gear 121 so that the gap between them is l _2. I can. According to this structure, the connector assembly and disassembly device 1 may be applicable to connectors having various sizes and spacings.

On the other hand, a bearing (no sign) may be installed around the fastening parts 14 and 15. The bearing is slidably connected to one side of the housing 11, so that the fastening parts 14 and 15 can be guided so that the fastening parts 14 and 15 are stably rotated while moving together with the movement of the fastening parts 14 and 15.

7 is a view showing an end portion of a first fastening portion according to an exemplary embodiment.

Referring to FIG. 7, when the two screws are not aligned or the angles of the tips 143 and 153 of the fastening portions 14 and 15 do not match the two screws at the same time, the fineness of the tip 143 You can see the structure that can be adjusted. In this case, by separating the detachable tip 143 with respect to the rotation transmission shaft 142 and rotating the fine adjustment protrusion 1431 with respect to the fine adjustment groove 1421, the tip 143 can be remounted at a different angle. . 7 shows the end of the first fastening part 14, but it is revealed that the same structure can be applied to the second fastening part 15 as well as the first fastening part 14. As shown in FIG.

The smaller the two devices 3a and 3b are, the narrower the space for assembling the connector 2 can be. In such a case, it is extremely difficult to directly insert the fastening tool 4 such as a driver in the axial direction of the screw provided in the connector 2. However, in the case of the connector assembly and disassembly device 1 according to the embodiment, since the length in the axial direction of the screw installed in the connector 2 is relatively short, it can be approached and assembled and disassembled as shown.

Meanwhile, although the user may directly rotate the handle 631 by hand, the fastening tool 4 may be separately inserted into the handle 631. For example, the fastening tool 4 may be provided with a driving means such as a motor capable of automatically rotating the handle 631. For example, the handle 631 may be provided with recessed applicator grooves 6311 and 6312 so that the fastening tool 4 can be engaged. The applicator grooves 6311 and 6312 may vary depending on the type of the fastening tool 4.
