Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of connector, in particular to a zipper type on-off connector device. BACKGROUND

[0002] In the field of electronic equipment assembly, electrical system integration, etc., as the core component of realizing circuit on-off and signal transmission, the plug-in efficiency and connection reliability of the connector directly affect the assembly quality and operation stability of the whole system. In the prior art, the batch plug-in device for the connector is usually arranged in a row by corresponding multiple male and female plugs, and all the male plugs are driven to simultaneously insert into the corresponding female plugs by a labor-saving mechanism (such as a lever mechanism), so as to realize the synchronous connection of multiple connectors. This kind of device improves the plug-in efficiency to a certain extent, and avoids the tedious operation of single plug-in, so it has been applied to a certain extent in batch production scenes.

[0003] In the implementation of the prior art, the inventors found that: Due to the individual differences in the machining precision, assembly error and plug-in resistance of multiple connectors, it is impossible to ensure that each male plug is completely inserted into the corresponding female plug during synchronous plug-in, and some male plugs may only achieve a half-plug-in state, resulting in unstable circuit connection, and subsequent manual inspection and secondary plug-in are required, which increases the process cost; during the synchronous plug-in process, all male plugs are forced to advance to the female plug under the action of the same driving force, and for male plugs with large plug-in resistance or positional deviation, the "hard top" phenomenon is likely to occur, causing the pins of the male plug to bend, deform or even break, directly leading to the damage of the connector, which not only increases the production loss, but also may cause safety hazards such as circuit short circuit due to the damaged connector.

[0004] Therefore, the present application provides a reliable batch plug-in connector technical solution, which ensures the plug-in efficiency, avoids the risk of hard plug damage, and ensures that each connector can achieve complete and stable connection, so as to meet the high-precision and high-reliability requirements of industrial production for batch connection of connectors, and solve the problems of poor plug-in integrity and damaged connectors in the prior art.

Detailed Implementation

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0018] Specifically, such as Figure 1 The diagram shown is an overall structural schematic of a zipper-type on / off connector device 100 provided in this application. This connector is mainly used to solve the problems of incomplete insertion, uneven force distribution, and easy damage to the pins caused by synchronous force application when multiple pairs of connectors are batch-connected. Its core lies in the use of a "zipper-type" step-by-step sequential insertion mechanism to reliably connect multiple pairs of male and female connectors in sequence.

[0019] The zipper-type on / off connector device 100 mainly includes four core parts: female plug array 10, male plug array 20, guide frame 30, and plug-in drive board 40.

[0020] Please refer to Figure 1 , Figure 2 and Figure 3 The female connector array 10 is used to provide a reference and flexible tolerance space for the connector. It includes multiple connectors along a first direction (i.e., Figure 1 The system includes female plug units 11 arranged at intervals in a left-right direction, and a floating mounting mechanism 112 for floating support of each female plug unit 11. Each female plug unit 11 includes at least one pair of female plugs 111 for electrical connection.

[0021] The floating mounting mechanism 112 is crucial for ensuring smooth insertion and confirming proper insertion. It mainly includes a mounting base 1121, a unit fixing block 1122, and elastic support components 1123 connected between the mounting base 1121 and the unit fixing block 1122, located on both sides of the female insertion unit 11. The mounting base 1121 has mounting holes 11211 for the female insertion unit 11 to pass through. The unit fixing block 1122 is used to fix a single female insertion unit 11. The unit fixing block 1122 has a female insertion mounting groove 11221 corresponding to the female insertion unit 111, and mounting recesses 11222 on both sides along the first direction. The elastic support components 1123 are connected between the mounting base 1121 and the unit fixing block 1122, and are partially accommodated within the mounting recesses 11222, allowing the unit fixing block 1122 and its fixed female insertion unit 11 to be positioned relative to the mounting base 1121 in an insertion direction perpendicular to the first direction (i.e.,...).Figure 1 The elastic floating is in the vertical direction (up-down direction).

[0022] More specifically, in combination with Figure 2 With Figure 3 , the elastic support assembly 1123 can include: a connecting plate 11231 fixed to the back of the mounting base plate 1121 by connecting bolts 1125 passing through the connecting holes, a through hole 112311 is formed in the middle of the connecting plate 11231; the connecting holes on both sides of the through hole 112311 are respectively formed in the two sleeve one 11232 fixed to the connecting plate 11231 and passing through the unit fixing block 1122; and two connecting guide columns 11233 connected to the unit fixing block 1122 at one end and having large-size limiting blocks at the other end and respectively extending into the two sleeve one 11232. A spring 11234 is sleeved on the connecting guide column 11233, and the two ends of the spring 11234 are respectively abutted on the unit fixing block 1122 and the limiting block at the end of the connecting guide column 11233, thereby providing the female plug unit 11 with an upward elastic support force.

[0023] Please refer to Figure 1 , Figure 4 and Figure 5 , the male plug array 20 is arranged in correspondence with the female plug array 10 up and down, for performing the plug-in action. It includes a plurality of male plug units 21 arranged at intervals in the first direction, and a driving block 212 fixed to each male plug unit 21. Each male plug unit 21 includes at least a pair of male plugs 211, and the male plugs 211 are provided with mounting bosses 2111 on both sides. The driving block 212 is correspondingly provided with a mounting groove 2122, and the opposite sides of the mounting groove 2122 are provided with a slot 2123. The male plug 211 is fixed by clamping the mounting bosses 2111 on both sides into the slot 2123 of the driving block 212, which is simple and reliable in structure.

[0024] Please refer to Figure 1 and Figure 6 , the guide frame 30 provides accurate guidance and limiting for the plug-in process. It includes an L-shaped limiting plate 31 extending in the first direction and a guide plate 32 fixed to the limiting plate 31. The L-shaped limiting plate 31 is composed of a first plate part 312 and a second plate part 313 connected vertically. On the first plate part 312, an avoidance slot 311 is formed corresponding to the position of each driving block 212, allowing the driving block 212 and the male plug unit 21 carried thereby to move up and down in the avoidance slot 311. The guide plate 32 is fixed to the second plate part 313, and a guide rail 321 extending in the first direction is formed on the plate surface of the guide plate 32 corresponding to each driving block 212.

[0025] Please refer to Figure 1 and Figure 7The plug-in driving plate 40 is a driving component of the device. The main body of the plug-in driving plate 40 is slidably arranged on the guide rail 321 of the guide plate 32. The lower end of the plug-in driving plate 40 is designed with a continuous driving slope 41.

[0026] The core driving and matching relationship of the device is that, as shown in Figure 4 , Figure 5 Each driving block 212 is machined with a driven slope 2121 at both ends in the first direction, which is matched with the driving slope 41 of the plug-in driving plate 40. The intersection position of the driven slopes 2121 at both ends of the driving block 212 is also provided with a rolling member, which is used to roll and move through the rolling member 2124 after the driving slope 41 of the plug-in driving plate 40 is inserted into the driven slope 2121. That is, the rolling member 2124 such as a roller or a bearing is installed in the groove of the driven slope 2121.

[0027] In addition, the male plug array 20 also includes a reset mechanism 213, which is arranged on both sides of the driven slope 2121 of the driving block 212. The reset mechanism 213 is arranged on both sides of the driven slope 2121 of the driving block 212, and the reset mechanism 213 includes an extension boss 2131 which is connected with the driving block 212 and is provided with a through hole, a sleeve two 2132 which is connected with the extension boss 2131 and corresponds to the through hole of the extension boss 2131, a connecting guide rod 2133 which passes through the through hole of the sleeve two 2132 and the extension boss 2131 and is connected with the limiting plate 31, and a reset spring 2134 which is sleeved on the connecting guide rod 2133 and is located between the sleeve two 2132 and the limiting plate 31. The guide plate 32 is provided with a through groove 322 at a position corresponding to the sleeve two 2132, so as to provide space for the movement of the reset mechanism.

[0028] Further, in order to ensure that the male plug unit 21 is completely plugged in place, as shown in Figure 2 , Figure 3 The unit fixing block 1122 is also provided with an abutting boss 1124 at a position corresponding to the through hole 112311, and the mounting base plate 1121 is provided with a through hole 11212 at a position corresponding to the abutting boss 1124. Figure 5 As shown in ,

[0029] The working principle and the plugging process of the device are as follows: In the initial state, the male plug array 20 is in the raised position under the action of the reset spring 2134 of the reset mechanism 213, and the male plug unit 21 is separated from the female plug unit 11. When batch plugging is required, the operator or external driving mechanism pushes the plugging driving plate 40 to slide in the first direction (for example, from left to right). The driving slope 41 at the front end of the plugging driving plate 40 first contacts and engages with the driven slope 2121 of the first (leftmost) driving block 212. Under the action of the slope, the first driving block 212 overcomes the force of its reset spring 2134 and drives the first male plug unit 21 to move downward and smoothly insert into the corresponding first female plug unit 11. In this process, if there is a slight alignment deviation, the female plug unit 11 can be slightly elastically adjusted by its floating installation mechanism 112 to avoid hard impact.

[0030] As the plugging driving plate 40 continues to advance, the driven slope 2121 of the first driving block 212 disengages from the driving slope 41, but its male plug unit 21 remains inserted in the state that the reset spring 2134 is compressed. At the same time, the driving slope 41 begins to engage with the driven slope 2121 of the second driving block 212, driving the second male plug unit 21 to insert downward. This cycle continues, like a zipper closing, all male plug units 21 are sequentially and orderly driven and inserted into the corresponding female plug units 21.

[0031] When a certain driving block 212 is driven to the lowermost end, i.e., its male plug unit 21 should be fully inserted, the abutting leg 214 of the driving block 212 will pass through the through hole 11212 of the installation base plate 1121 downward and contact and press against the abutting boss 1124 of the female plug unit 11 below. This action forces the unit fixing block 1122 of the female plug unit 11 to produce a slight additional elastic displacement by compressing its spring 11234. This "abutting" confirms that the pair of connectors has been fully plugged in place in structure, providing reliable feedback on the completion of plugging.

[0032] When the connectors need to be separated, the plugging driving plate 40 is simply pulled out. Each driving block 212 is sequentially reset upward under the action of the reset spring 2134 of its reset mechanism 213, driving the male plug unit 21 to separate from the female plug unit 11, and the entire process is also orderly and gentle.

[0033] The above is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
