A limiting groove with a width adapted to the width of the connector is opened on the top surface of the slot body. The front baffle is set at one end of the slot body and is directly opposite the end of the limiting groove. The rear baffle is located at the end of the slot body opposite to the front baffle and is also directly opposite the end of the limiting groove. A through groove adapted to the outer diameter of the wire harness is opened on the top surface of the rear baffle. The width of the through groove is smaller than the width of the end of the back cover near the rear baffle. The through groove and the limiting groove are coaxially arranged. The rear baffle is connected to the push rod of the cylinder. The extension and retraction direction of the cylinder is parallel to the axial direction of the through groove.

[0005] As a preferred embodiment, the cylinder is connected to the air source through a three-way solenoid valve, the control terminal of the three-way solenoid valve is electrically connected to a foot switch, and the three-way solenoid valve is controlled by the foot switch.

[0006] As a preferred embodiment, the width of the end of the rear cover facing the connector is the same as the width of the connector.

[0015] The specific implementation scheme of this utility model will now be described in detail with reference to the accompanying drawings.

[0016] Figure 2 The quick-assembly device for the wire harness connector back cover shown is used for assembly. Figure 1The connector 8 and the back cover 9 are shown. The quick assembly device for the rear cover of the wire harness connector includes a slot body 4 and a front baffle 5 for positioning the connector 8, a rear baffle 3 for pressing the rear cover 9, and a cylinder 1 for driving the rear baffle 3 to move toward the connector 8. The slot body 4, the front baffle 5, the rear baffle 3, and the cylinder 1 are all connected to a base 7. The top surface of the slot body 4 has a limiting groove 10 with a width adapted to the width of the connector 8. The front baffle 5 is located at one end of the slot body 4 and is directly opposite the end of the limiting groove 10. The rear baffle 3 is located at the end of the slot body 4 opposite to the front baffle 5 and is also directly opposite the end of the limiting groove 10. The top surface of the rear baffle 3 has a through groove 12 adapted to the outer diameter of the wire harness 11. The width of the through groove 12 is smaller than the width of the end of the rear cover 9 near the rear baffle 3. The through groove 12 and the limiting groove 10 are coaxially arranged. The rear baffle 3 is connected to the push rod of the cylinder 1. The extension and retraction direction of the cylinder 1 is parallel to the axial direction of the through groove 12.

[0017] In this embodiment, cylinder 1 is connected to the air source through a three-way solenoid valve 2. The control end of the three-way solenoid valve 2 is electrically connected to the foot switch 6. The three-way solenoid valve 2 is controlled by the foot switch 6 to free up the worker's hands for loading and unloading.

[0018] like Figure 1 As shown, the width of the end of the rear cover 9 facing the connector 8 is the same as the width of the connector 8. The end of the connector 8 facing the rear cover 9 radially contracts inward to form a plug body 15. The end of the rear cover 9 facing the connector 8 has a sleeve interface 16 that fits tightly with the plug body 15. The plug body 15 is provided with a slot 17. The inner wall of the rear cover 9 is provided with a hook 18 that matches the slot 17. The length of the slot body 4 along the axial direction of the limiting groove 10 is greater than the length of the plug body 15. The length of the connector 8 at the end of the plug body 15 facing away from the rear cover 9 is greater than the distance between the slot body 4 and the front baffle 5. When the connector 8 abuts against the front baffle 5, the plug body 15 is just located in the limiting groove 10 of the slot body 4.

[0019] like Figure 3 As shown, to prevent damage to the connector 8 structure caused by premature compression of the connector 8 and rear cover 9 due to excessive dimensional tolerances, this embodiment further provides a support plate 13 on the side of the front baffle 5 opposite to the slot body 4. The support plate 13 is parallel to the front baffle 5, and a support spring 14 is provided between the support plate 13 and the front baffle 5. The front baffle 5 can be slidably connected to the base 7 via a track, and under the elastic force of the support spring 14, it blocks the connector 8. The elastic force provided by the support spring 14 is greater than the squeezing force when the rear cover 9 and the connector 8 are fitted together, but less than the thrust provided by the cylinder 1. With this improvement, when the connector 8 and the rear cover 9 are compressed, if the cylinder 1 continues to drive the rear baffle 3 to squeeze the rear cover 9, the connector 8 can push the front baffle 5 towards the support plate 13, thereby avoiding excessive compression and damage to the connector 8.

[0020] There are various ways to slide the front baffle 5 and the base 7. This embodiment only shows one common one by example. All sliding pairs that can be used for linear sliding connection disclosed before the application date of this utility model can be used in this utility model.

[0021] like Figure 3 As shown, this embodiment also has multiple through slots 12 on the rear baffle 3, and the number of front baffles 5 is the same as the number of through slots 12. The front baffles 5 correspond one-to-one with the through slots 12, and the slot body 4 has limiting slots 10 that correspond one-to-one with the through slots 12. In this way, workers can assemble the connectors 8 and the rear cover 9 on multiple wire harnesses 11 at one time, further improving production efficiency.

[0022] The working process of this utility model is as follows: First, the quick assembly device for the rear cover of the wire harness connector is started, and then the worker loads the material. When loading the material, the worker places the wire harness 11 connected to the connector 8 onto the quick assembly device for the rear cover of the wire harness connector, so that the connector 8 is located in the limiting groove 10 and abuts against the front baffle 5. The wire harness 11 is then embedded in the through groove 12. At this time, the rear cover 9 is sleeved on the wire harness 11 and pre-connected with the connector 8. Pre-connection means that the rear cover 9 and the plug body 15 of the connector 8 have a small amount of contact. This kind of contact only requires the worker to provide a small force to complete, so as to maintain the accurate contact relationship between the connector 8 and the rear cover 9.

[0023] After the worker presses the foot switch 6, the cylinder 1 drives the rear baffle 3 to move towards the slot 4. When the rear baffle 3 contacts the rear cover 9, it pushes the rear cover 9 towards the connector 8, pressing the rear cover 9 onto the plug body 15, causing the hook 18 to engage with the slot 17. After the worker releases the foot switch 6, the cylinder 1 resets, causing the rear baffle 3 to reset as well. The worker then unloads the components and repeats the above process to assemble the connectors 8 and rear covers 9 of all wire harnesses 11.

[0024] When the quick assembly device for the wire harness connector back cover is equipped with multiple limiting grooves 10 and through grooves 12, the worker can set up multiple wire harnesses 11 at one time and assemble the connectors 8 and back covers 9 on the multiple wire harnesses 11 simultaneously.

[0025] Although manual labor is still required during the assembly of connector 8 and back cover 9, the assembly efficiency can be significantly improved compared to manually pressing the back cover 9 onto connector 8.

[0026] As can be seen, this utility model uses cylinder 1 to push rear baffle 3 to squeeze rear cover 9, and at the same time uses slot body 4 and front baffle 5 to limit connector 8, so that rear cover 9 and connector 8 can quickly engage and lock, realize the rapid assembly of wire harness connector rear cover, improve work efficiency and reduce labor costs.

[0027] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some examples of its application, and are not intended to limit the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
