Description

Technical Field

[0001] The present invention relates to a cable assembly, in particular to a cable assembly with on-off functions and a manufacturing method thereof. Background Art

[0002] Military equipment plays a vital role in modern warfare. The ignition and standby states of the equipment's engines are controlled by its launch system. Specifically, the switch device in the launch system controls the ignition and standby states of the equipment's engines, which is directly related to whether the military equipment can be quickly and accurately deployed in combat at critical moments. This requires reliable triggering of the switch device in the equipment's launch system and the ability to achieve reliable signal transmission within the military equipment. The connector in the switch device is connected to the cable used for communication within the equipment to form a cable assembly. Currently, the triggering of the switch device is implemented as follows: the connector used for communication within the equipment is inserted into the base, the connector is connected to the cable, and then a baffle is used to block the connector to prevent it from falling out of the base, thereby ensuring stable insertion of the connector and the adapter connector, achieving stable signal transmission in the cable. The existing traditional baffle has no error-proofing design and is a symmetrical structure. During assembly, it cannot be precisely matched with the connector. If it is installed in the wrong orientation, the switch cannot be triggered immediately and accurately within the specified time, and the reliable triggering requirement of the launch system switch device cannot be achieved.

[0003] Furthermore, in the prior art, if the installation position of the switch device on the base cannot be accurately positioned with the position of the connector, the connector cannot successfully trigger the switch device during ignition, resulting in ignition failure. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a cable assembly with on-off functions and a manufacturing method thereof.

[0005] The objective of the present invention is achieved by adopting the following technical solution: According to the present invention, a cable assembly with a switch function includes a base, the base having an insertion hole and a filling hole connected to the insertion hole, a connector inserted into the insertion hole, a rear end face of the connector protruding with a straight protrusion and an inclined protrusion, a rear end face of the base having a stopper for blocking the straight protrusion to prevent the connector from axially escaping from the insertion hole, and a micro switch; the filling hole is filled with gunpowder and sealed, and after the gunpowder explodes, it pushes the connector, causing the inclined surface of the inclined protrusion to approach, contact, and squeeze the contacts of the micro switch to trigger the micro switch.

[0006] Furthermore, the cable at the rear end of the connector is molded with glue to avoid the contacts of the micro switch.

[0007] Furthermore, a stopping step for stopping the connector axially forward is provided in the insertion hole.

[0008] Furthermore, the straight protrusions and the inclined protrusions protruding from the end face of the connector tail end are distributed at 90 degrees.

[0009] Furthermore, an outer side of the top of the inclined surface protrusion is provided with an inclined surface that matches the contact point, so that the thickness of the top of the inclined surface protrusion gradually decreases in the protruding direction.

[0010] Furthermore, the blocking piece is a C-shaped structure, the blocking piece and the micro switch surround the outside of the insertion hole, and a protruding piece is protruded from the inner side of the blocking piece for blocking the protrusion of the straight surface.

[0011] A method for manufacturing a cable assembly with a switching function, comprising the following steps:

[0012] Install the micro switch fixture into the insertion hole of the base and place the micro switch on the rear end surface of the base;

[0013] Circularly adjust the position of the micro switch on the rear end surface of the base and rotate the micro switch fixture to rotate it in the insertion hole until the thin section, gradient section, and thick section of the variable diameter protrusion on the micro switch fixture pass through the contact of the micro switch in sequence, and the following state occurs: the contact contacts the gradient section when moving from the thin section to the gradient section and is gradually compressed. When the contact passes through the gradient section, a sound of the micro switch being triggered can be heard. Continue to rotate the micro switch fixture to make the contact change from the gradient section to the thick section, so that the contact continues to be compressed. At this time, the position of the micro switch is determined;

[0014] Install the connector into the insertion hole of the base, and fix the micro switch on the base according to the determined position;

[0015] Turn the connector so that the inclined protrusion at the rear of the connector is in front of the micro switch contacts;

[0016] Assemble the baffle so that the straight-faced projection on the rear of the connector is in front of the baffle tab.

[0017] Furthermore, the shape of the front end of the micro switch tooling is the same as that of the front end of the connector, and a handle is provided on the rear end face of the micro switch tooling, and the handle is turned to rotate the micro switch tooling in the insertion hole.

[0018] Furthermore, a diameter-changing protrusion is provided on the edge of the rear end face of the micro switch fixture. In the rotation direction of the micro switch fixture, the diameter-changing protrusion is divided into a thin section, a gradual section, and a thick section in sequence.

[0019] Furthermore, the connector is limited in the base and connected to the cable, and the outlet direction of the cable avoids the contact of the micro switch. The cable is molded by glue injection, so that the cable direction is pre-formed.

[0020] Compared with the prior art, the present invention is beneficial in that:

[0021] The present invention proposes a cable assembly that can position a microswitch so that the microswitch is accurately triggered when the connector is pushed out by gunpowder. The cable assembly can be integrally mounted and formed, and uses a baffle with a special structure. The baffle is designed with a limit structure that cooperates with the inclined protrusion and straight protrusion on the connector to ensure reliable triggering of the microswitch and achieve smooth ignition of the engine. The beneficial effects of the present invention are summarized as follows:

[0022] (1) The present invention designs an installation structure with a base, which realizes the integrated installation and molding of the micro switch, connector and base, and realizes modular assembly for users.

[0023] (2) The present invention adopts a baffle with a special structure and a straight-face protrusion on the end face of the connector tail end, which solves the problem of the baffle pin bouncing in the prior art and realizes the smooth triggering of the micro switch.

[0024] (3) The present invention designs a gunpowder limiting structure, which realizes the conversion of the lateral force generated by the gunpowder explosion into an axial force, accurately and reliably triggers the micro switch, and ensures the accurate and smooth ignition of the equipment engine.

[0025] (4) The present invention accurately locates the position of the micro switch through the micro switch tooling. After installation, the inclined surface on the inclined protrusion on the connector smoothly pushes and squeezes the contacts of the micro switch to ensure that the micro switch is smoothly triggered to achieve ignition.

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] An embodiment of a cable assembly with on-off function according to the present invention is as follows: Figures 1 to 6 shown.

[0049] The cable assembly includes a cable, a connector 1 connected to the cable, a base 2 for inserting the connector 1, a micro switch 3 and a baffle 4 provided on the base 2. The cable assembly is described with the rear end of the connector 1 as the rear end.

[0050] The base 2 is provided with an insertion hole 21 for inserting the connector 1 . The micro switch 3 and the blocking piece 4 are arranged on the end face where the insertion hole 21 is located and are located on the rear end face of the base 2 close to the tail end of the connector 1 .

[0051] A stopping step 23 is provided on the inner wall of one end of the insertion hole 21. When the connector 1 is inserted into the insertion hole 21, the stopping step 23 stops the connector 1 forward, and then a blocking piece 4 is provided on the rear end face of the base 2 to stop the tail end of the connector 1 backward to prevent the connector 1 from falling out of the base 2.

[0052] The rear end face of connector 1 is equipped with two protrusions arranged at 90° angles: an inclined protrusion 11 and a straight protrusion 12. Both protrusions are sheet-like structures arranged vertically on the rear end face of the connector, and the two protrusions are close to the edge of the rear end face of connector 1. In this embodiment, connector 1 is a circular connector with a circular rear end face. The two protrusions are close to the edge of the rear end face, so they are bent along the edge of the rear end face.

[0053] The outer edge of the top of the inclined surface protrusion 11 is chamfered so that the outer edge of the top of the inclined surface protrusion 11 forms an inclined surface, so that the thickness of the top of the inclined surface protrusion 11 gradually decreases in the protruding direction.

[0054] The two protrusions on the end face of the connector tail are designed to prevent errors. The two protrusions are distributed at 90 degrees and have different shapes. One is a protrusion with a bevel and the other is a protrusion without a bevel, which is easy to distinguish and avoids the occurrence of incorrect insertion orientation when inserting the connector 1.

[0055] The direction of extension and retraction of contact 31 on microswitch 3 is perpendicular to insertion hole 21, and contact 31 faces insertion hole 21. The inclined surface of inclined protrusion 11 on connector 1 matches microswitch 3, and inclined protrusion 11 is located in front of contact 31 on microswitch 3. That is, the line between the end of contact 31 and inclined protrusion 11 is parallel to the axis of insertion hole 31. When connector 1 is pulled backward, the inclined surface of inclined protrusion 11 can contact and squeeze the end of contact 31, causing microswitch 3 to trigger. Microswitch 3 controls the ignition of the equipment engine, thereby igniting the equipment engine.

[0056] In order to make the inclined protrusion 11 squeeze the contact 31 when the inclined protrusion 11 is pulled out backwards and the micro switch 3 is triggered smoothly, it is necessary to accurately locate the position between the micro switch 3 and the insertion hole 21 (or the connector 1). In this embodiment, the micro switch fixture 5 is used to realize the positioning of the micro switch. Figure 10a 、 Figure 10b shown.

[0057] The front end of the microswitch fixture 5 has the same shape as the front end of the connector 1. After the microswitch fixture 5 is inserted into the insertion hole 21, the microswitch fixture 5 is stopped forward by the stop step 23. The rear end of the microswitch fixture 5 is provided with a handle 51. Turning the handle 51 rotates the microswitch fixture 5 within the insertion hole 21. The edge of the rear end of the microswitch fixture 5 is provided with a reducing protrusion 52. The microswitch fixture 51 is generally circular, and its rear end is also circular. The reducing protrusion 52 is close to the edge of the rear end and has an overall arc shape. In the direction of rotation of the microswitch fixture 5, the reducing protrusion 52 is divided into a thin section 521, a gradual section 522, and a thick section 523. The thickness of the thin section 521 is smaller than that of the thick section 523, and the thickness of the gradual section 522 gradually increases from the thin section 521 to the thick section 523. The inner concave surface of each section of the variable diameter protrusion 52 is a complete arc surface. Therefore, the outer concave surface of each section of the variable diameter protrusion 52 is divided into three arc surfaces with different radii, and the arc surface of the gradual section 522 is an arc surface with a gradually changing radius, making the outer arc surface of the variable diameter protrusion 52 uneven.

[0058] The shape of the variable diameter protrusion 52 is designed to match the inclined surface protrusion 11. When the connector 1 is disengaged from the insertion hole 21, the inclined surface on the inclined surface protrusion 11 gradually approaches the contact 31 and then contacts the contact 31. As the inclined surface protrusion 11 continues to move backward, the inclined surface squeezes the contact 31, causing the micro switch 31 to gradually retract and trigger (the micro switch may make a sound when triggered). Then the inclined surface protrusion 11 continues to be disengaged backward until the connector 1 is disengaged from the insertion hole 21. Correspondingly, the micro switch fixture 5 is designed according to the shape and working state of the inclined surface protrusion 11. When the micro switch fixture 5 is rotated, the thin section 521 does not contact the contact 31. As the micro switch fixture 5 continues to rotate, the gradient section 522 contacts the contact 31, causing the contact 31 to retract. As the micro switch fixture 5 continues to rotate, the contact 31 continues to retract until it is triggered. As the micro switch fixture 5 continues to rotate to the thick section 523, the contact 31 continues to be squeezed. Figure 11 shown.

[0059] When installing the micro switch 3, insert the micro switch tool 5 into the insertion hole 21, temporarily position the micro switch 3 on the rear end face of the base 2, and rotate the micro switch tool 5. If the action state of the reducing protrusion 52 and the contact 31 is consistent with the action state of the above design, it means that the micro switch 3 is installed in place; if the reducing protrusion 52 and the contact 31 do not contact from the beginning to the end, it means that the micro switch 3 is too far away from the insertion hole 21, and the position of the micro switch 3 needs to be adjusted; if the reducing protrusion 52 squeezes the contact 31 at the beginning, it means that the micro switch 3 is too close to the insertion hole 21, and the position of the micro switch 3 needs to be adjusted; until the gradual section 522 of the reducing protrusion 52 can gradually approach the contact 31, contact the contact 31, trigger, and continue to squeeze the contact 31, it means that the position of the micro switch 3 is appropriate, and then the position of the micro switch 3 is determined. During the assembly process, the micro switch 3 is assembled according to this position.

[0060] After the position of the micro switch 3 is determined and installed by the micro switch tool 5, the trigger failure caused by the inclined protrusion 11 not contacting the contact 31 when the connector 1 is disengaged from the insertion hole 21 can be avoided; the trigger failure caused by the inclined protrusion 11 directly breaking the contact 31 can also be avoided.

[0061] The baffle 4 features a U-shaped, error-proof design. A protrusion 41 protrudes from the inner side of one side, making it asymmetrical and preventing incorrect installation orientation. The baffle 4 and the microswitch 3 wrap around the edge of the insertion hole 21. The protrusion 41 mates with the straight-faced protrusion 12 of the connector, which is located in front of the protrusion 41. This prevents the connector 1 from moving backward, thereby preventing the inclined protrusion 11 from accidentally contacting the contact 31 of the microswitch 3.

[0062] After the baffle 4 is mounted on the base 2, if the inclined protrusion 11 of the connector 1 is not located under the contact 31, the straight protrusion 12 cannot be located in front of the protruding piece 41. Figure 7 As shown, it is impossible to simultaneously realize that the protruding piece 41 of the baffle 4 presses the straight protrusion 12 of the connector and the inclined protrusion 11 of the connector 1 is located under the contact 31, which makes it easy for the connector 1 to fall out, thereby failing to assemble the cable assembly and thus achieving error-proof installation of the baffle 4 position. Figure 8 During assembly, the beveled protrusion 11 of connector 1 is located in front of the protruding piece 41 of baffle 4, and the straight protrusion 12 is located in front of the contact 31. During assembly, the asymmetrical structure of baffle 4 makes it easy to identify and prevent incorrect installation. During assembly, it is necessary to ensure that the beveled protrusion 11 matches the contact 31 of microswitch 3 and is located in front of the contact 31, and that the straight protrusion 12 is located in front of the protruding piece 41 of baffle 4. This ensures a unique assembly position, and there is no alternative installation orientation.

[0063] After the micro switch 3 is positioned and installed on the base 2, the micro switch 3 is located on one side of the insertion hole 21, and the baffle 4 is set on the other side of the insertion hole 21. Since the baffle 4 is a U-shaped structure, the baffle 4 and the micro switch 3 can surround the insertion hole 21. Therefore, after the position of the micro switch 3 is determined, the position of the baffle 4 can be quickly located.

[0064] A powder launcher 22 is mounted on base 2. This launcher 22 includes a filling hole 22, perpendicular to and connected to insertion hole 21, for filling with powder. After filling hole 22 with powder, it is sealed, forming a sealed structure. In this embodiment, a relatively weak sealing material is installed at the location where filling hole 22 communicates with insertion hole 21, and a relatively strong sealing material is installed elsewhere. This maximizes the force of the powder explosion into an axial force applied to connector 1.

[0065] By adopting the special limiting structure of the baffle 4, at the moment of ammunition ignition, since the gunpowder launch tube is designed as a sealed structure, the lateral force generated by the gunpowder explosion is converted into an axial force at the moment of ignition. Figure 9 As shown, the connector is bounced up along the axial force direction, and the straight protrusion 12 breaks the protruding piece 41 of the blocking piece 4. The inclined protrusion 11 of the connector 1 triggers the contact 31 of the micro switch, realizing the smooth triggering of the micro switch 3 and ensuring the accurate ignition of the equipment engine.

[0066] The thickness of the baffle 4 must be precisely designed, with strict thickness tolerances, to ensure that the force generated by the explosive charge causes the straight protrusion 12 on the connector 1 to directly break through the protruding piece 41 of the baffle 4. At the same time that the straight protrusion 12 on the connector 1 breaks through the protruding piece 41, the inclined surface of the inclined protrusion 11 squeezes the contact 31, triggering the microswitch 3 with precise timing and within a very short time.

[0067] The outgoing line direction at the tail end of the connector 1 is staggered from the installation position of the micro switch 3, which does not affect the triggering of the micro switch 3. The outgoing line at the tail end is molded by glue, and the wiring harness is pre-formed, away from the contact 31 of the micro switch to avoid accidental touch.

[0068] The present invention proposes a cable assembly that can position a micro switch 3 so that the micro switch 3 is accurately triggered when the connector 1 is pushed out by gunpowder. The cable assembly can be integrally mounted and formed, and uses a baffle 4 with a special structure. The baffle 4 is designed with a limiting structure (protrusion 41) that cooperates with the inclined protrusion 11 and the straight protrusion 12 on the connector 1 to ensure reliable triggering of the micro switch 3 and achieve smooth ignition of the engine. The beneficial effects of the present invention are summarized as follows:

[0069] (1) The present invention designs an installation structure with a base 2, which realizes the integrated installation and molding of the micro switch 3, cable, connector 1 and base 2, and realizes modular assembly for users.

[0070] (2) The present invention adopts a baffle with a special structure and a protrusion on the end face of the connector tail end, which solves the problem of the baffle pin bouncing in the prior art and realizes the smooth triggering of the micro switch 3.

[0071] (3) The present invention designs a gunpowder limiting structure (a gunpowder launcher perpendicular to the insertion hole where the connector 1 is located), which realizes the conversion of the lateral force generated by the gunpowder explosion into an axial force, accurately and reliably triggers the micro switch 3, and ensures the accurate and smooth ignition of the equipment engine.

[0072] (4) The present invention accurately locates the position of the micro switch 3 through the micro switch tool 5. After installation, the inclined surface on the inclined protrusion 11 on the connector 1 smoothly pushes and squeezes the contact 31 of the micro switch 3, ensuring that the micro switch 3 is smoothly triggered to achieve ignition.

[0073] In other embodiments of a cable assembly with an on-off function of the present invention, on the basis of the above embodiment, the micro switch tooling 5 can be replaced by a tooling with the same outer contour structural dimensions as the connector 1, and a handle is provided at the tail of the tooling. After adjusting the position of the micro switch 3, the tooling is pulled outward so that the inclined protrusion at the tail of the tooling contacts, squeezes, and triggers the contact 31, and the action process is consistent with the action process of the connector 1, thereby determining the position of the micro switch 3.

[0074] In other embodiments of a cable assembly with a switching function of the present invention, based on the above embodiment, the baffle 4 can also be of other shapes, as long as the protruding piece 41 on the baffle 4 can block the straight-face protrusion 12 of the connector 1 to prevent the connector 1 from moving backward in the insertion hole 21, and the protruding piece 41 can be broken after the gunpowder explodes to release the blocking of the connector 1.

[0075] In other embodiments of a cable assembly with an on-off function of the present invention, based on the above embodiments, the extension direction of the filling hole 22 may not be perpendicular to the insertion hole 21, and may be set at an angle, and the inclination direction may be toward the rear end, so that the force of the gunpowder explosion can be converted into axial force as much as possible to achieve instant triggering.

[0076] An embodiment of a method for manufacturing a cable assembly with a switching function according to the present invention is as follows: Figures 11 to 13 As shown, the following steps are included:

[0077] 1) Install the micro switch fixture 5 into the insertion hole 21 of the base 2, and place the micro switch 3 on the rear end surface of the base 2 where the insertion hole 21 is located, as shown in the figure. Figure 11 shown.

[0078] 2) Circularly adjust the position of the micro switch 3 on the rear end surface of the base 2, and twist the handle 51 of the micro switch fixture 5 to rotate the micro switch fixture 5 in the insertion hole 21 until the thin section 521, the gradient section 522, and the thick section 523 of the diameter-reducing protrusion 52 on the micro switch fixture 5 pass the contact 31 in sequence. The following state occurs: after the contact 31 moves from the thin section 521 to the gradient section 522, it contacts the gradient section 522 and is gradually compressed. A crisp sound can be heard when the contact 31 passes through the gradient section 522. This is the sound of the micro switch 3 being triggered. Continue to rotate the micro switch fixture 5 so that the contact 31 moves from the gradient section 522 to the thick section 523. You can see that the contact 31 continues to be compressed. At this time, the position of the micro switch 3 is determined.

[0079] 3) Install the connector 1 into the base 2 and fix the micro switch 3 on the base 2 according to the determined position.

[0080] 4) After inserting the connector 1 into the insertion hole 21 of the base, rotate the connector 1 to Figure 12 In the position shown, the inclined protrusion 11 at the rear of the connector housing 1 is centered in front of the contact 31 of the micro switch 3 .

[0081] 5) Assemble the baffle 4 so that the inclined protrusion 11 at the rear of the connector housing is centered in front of the contact 31 of the micro switch, and the straight protrusion 12 is centered in front of the protruding piece 41 of the baffle 4.

[0082] 6) Connect the connector 1 to the cable, and make the outgoing line avoid the contact 31 of the micro switch 3. The cable at the end of the connector is molded with glue, so that the cable runs in the pre-molded direction to ensure that it does not touch the contact 31.

[0083] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and alterations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
