Technical Field

[0001] This utility model relates to the field of connector insertion and removal detection technology, and more specifically, to an automotive connector insertion and removal detection mechanism. Background Technology

[0002] As a key component of automotive electronic systems, the plugging and unplugging force of automotive connectors directly affects the reliability of circuit connections and the safety of the entire vehicle. Therefore, the plugging and unplugging force of connectors must be tested before leaving the factory.

[0003] Currently, the industry mostly uses manual sampling or fixed testing equipment for connector insertion and extraction force testing. Manual sampling is inefficient and has insufficient coverage, which can easily lead to defective products entering the market; while fixed testing equipment cannot be integrated into the production line, requiring interruption of the production process and reducing overall efficiency.

[0004] Therefore, there is an urgent need for a plug-in / plug-out testing mechanism capable of continuous online testing. Utility Model Content

[0005] The purpose of this invention is to provide an automotive connector insertion and removal testing mechanism to solve the problem that it is inconvenient to perform batch insertion and removal testing of connectors in the prior art.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] An automotive connector insertion and removal testing mechanism is provided for batch insertion and removal testing of connectors. It is an integrated testing mechanism consisting of an adjustable side seat 12, a standard part 14, and an insertion and removal force testing unit 1212. It can be directly installed above the transmission equipment on the production line, eliminating the need for traditional fixed equipment testing. It can perform insertion and removal testing in a timely manner after the connector production process, effectively preventing defective products from entering the market.

[0033] In some embodiments, the specific structure of the automotive connector insertion / removal detection mechanism is as follows: Figure 1-4 As shown, it includes an integrated detection mechanism that is detachably mounted above the transmission equipment;

[0034] The testing mechanism includes a fixed base 11, a side base 12, and a standard component 14;

[0035] The mounting bases 11 are symmetrically installed in pairs above the frame of the transmission equipment, and the sides of the mounting bases 11 extend downwards. The height can be adjusted by connecting the mounting bases 11 to the extension plate and the frame with bolts.

[0036] Side seat 12 includes a base plate 121 and a top plate 122;

[0037] The base plate 121 is located above the conveyor belt of the transmission equipment, and the top plate 122 is installed above the base plate 121 by a lifting device, forming a partition between the two, corresponding to the insertion interfaces at both ends of the connector.

[0038] Furthermore, an upwardly extending side stop 1211 is fixed to the outer side of the base plate 121, and an insertion and extraction force testing unit 1212 is installed on the inner side of the side stop 1211.

[0039] It should be noted that the insertion and extraction force testing unit 1212 preferably adopts an integrated structure of a high-precision force sensor (such as a strain gauge or piezoelectric sensor) and a miniature electric push rod. The push rod is driven by a controller to achieve reciprocating motion, simulating insertion and extraction actions. The force sensor detects the insertion and extraction force data in real time and transmits it to the external quality control system through a data interface (such as RS485 or Ethernet).

[0040] Standard part 14 is located in the partition space, and its inner surface is integrated with a connector for plugging and unplugging.

[0041] It should be noted that the inside of standard part 14 has mating terminals (such as copper alloy pins) that match the connector under test, and the terminal layout can be changed according to the connector model.

[0042] Among them, one end of the standard part 14 is fixed with a positioning plate 141, which extends inward to block the connector for transmission and forms a positioning.

[0043] Furthermore, the outer side of the standard part 14 is fixedly connected to the movable end of the insertion and extraction force testing unit 1212 by bolts;

[0044] In addition, a bidirectional transmission rod 13 is rotatably installed between adjacent fixed seats 11. An equipment box is fixedly installed on the outer side of the upper end of one of the fixed seats 11, which contains a micro rotary motor to drive the bidirectional transmission rod 13 to rotate.

[0045] Among them, the bidirectional transmission rod 13 is a two-section ball screw structure with opposite thread directions on the left and right sections (one section is left-handed and the other is right-handed).

[0046] Furthermore, a transmission seat 1221 is fixedly installed on the upper end of the top plate 122. It is a double-layer plate structure, and a spiral sleeve is fixedly installed between the two layers for transmission connection with the bidirectional transmission rod 13.

[0047] It is understandable that the rotational movement of the bidirectional transmission rod 13 drives the two sets of side seats 12 to move inward or away from each other simultaneously via the spiral sleeve, thereby achieving the effect of clamping the connector for positioning and releasing the positioning.

[0048] It should be noted that by integrating the insertion and extraction force testing unit 1212 into the testing mechanism, and combining the adjustable structure of the testing mechanism, it can be installed on the transmission equipment in various production processes, thereby eliminating the traditional fixed equipment sampling inspection method in testing operations.

[0049] like Figure 2As shown, both ends of the bottom plate 121 and the top plate 122 have protruding plates 1201.

[0050] Among them, a lifting part 15 is installed above the convex plates 1201 at both ends of the top plate 122, and the movable end of the lifting part 15 extends downward to connect to the convex plates 1201 at both ends of the bottom plate 121.

[0051] It should be noted that the lifting part 15 is preferably an electric telescopic device.

[0052] like Figure 3 and Figure 4 As shown, a boss 1411 is fixedly installed on the outer side of the standard part 14;

[0053] A fixing bracket 12121 is fixedly installed on the inner side of the insertion and extraction force testing unit 1212;

[0054] The inner side of the fixing bracket 12121 has a square groove structure, corresponding to the boss 1411, and the two are fixed by bolts.

[0055] Understandably, the detachable connection between the boss 1411 and the mounting bracket 12121 allows for convenient switching of different standard parts 14 for insertion and removal testing when changing connector models.

[0056] In some publicly available publications, the specific usage methods of automotive connector plug-in / plug-out testing mechanisms are as follows:

[0057] S1. Place the detection mechanism above the conveyor belt of the transmission equipment, activate the lifting part 15 to extend it, thereby lifting the top plate 122 upward, forming a partition between the bottom plate 121 and the top plate 122 to cover the connector. At this time, the bottom plate 121 and the top plate 122 can abut against the upper and lower edges of the connector.

[0058] S2. The rising top plate 122 drives the fixed seat 11 to rise. The plate extending downward from the side of the fixed seat 11 is connected and fixed to the frame of the transmission equipment by bolts, or the fixed seat 11 is fixed by a screw combined with a rubber pad through a tightening force.

[0059] S3. Start the rotary motor in the equipment box above one of the fixed seats 11, drive the bidirectional transmission rod 13 to rotate, and use the transmission structure of its two sections of the body with opposite rotation directions to drive the adjacent side seats 12 to move towards each other through the spiral sleeve installed on the side of the transmission seat 1221 above the top plate 122, leaving a channel for the connector to pass through.

[0060] S4. The connector is conveyed above the conveyor belt. When it moves to the predetermined position, it stops conveying by abutting the positioning plate 141. Then, the insertion and extraction force test unit 1212 is started, which moves the fixing frame 12121 at its front end back and forth, thereby driving the standard part 14 to move closer to and away from the connector, so that the connector integrated on the inner side of the standard part 14 and the connector can be inserted and extracted to form a test.

[0061] S5, the reverse rotation of the bidirectional transmission rod 13 causes the adjacent side seats 12 to move away from each other at the same time, thereby expanding the reserved space between the adjacent side seats 12 and the connector transmission is moved out.

[0062] S6. When switching connector models, remove the bolts connecting the boss 1411 and the fixing bracket 12121, and replace the corresponding standard part 14 to continue the insertion and removal test.
