Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, specifically a terminal connector to prevent terminals from being misaligned. Background Technology

[0002] Terminal misalignment is one of the most frequent defects in the wire harness assembly industry. This defect can lead to functional problems and potential hazards in the wire harness. Currently, preventing terminal misalignment at the production station usually involves requiring operators to follow the push, listen, and pull operation procedures. Some error detection methods also involve checking the terminal status at the back end.

[0003] Current process error prevention methods rely heavily on operator perception as the judgment standard. Operators are prone to misjudgment or errors when they are fatigued or inattentive. However, back-end terminal status detection is not considered process error prevention. If the detection method fails, there is a possibility of defective products being released. To address these issues, we have provided a terminal connector to prevent misalignment of terminals. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a terminal connector to prevent misalignment of terminals. This device allows for the use of a permanent marking method on the surface of the wires, such as laser marking or inkjet printing, before the wire harness is assembled. This ensures that the operator is visually reminded to complete the terminal assembly work as required, avoiding the outflow of defective products when the back-end detection method fails, and can stably guide the wires during the insertion process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a terminal connector for preventing misalignment of terminals, comprising a connector body, wherein a terminal connector is installed inside the connector body, and a cable connected to the terminal connector is disposed outside the connector body, wherein a marking ring is disposed on the outer surface of the cable, and an auxiliary mechanism for guiding the cable is disposed outside the connector body.

[0006] Furthermore, the marking ring can be permanently marked on the cable surface, such as by laser marking or inkjet printing. This step depends on the cable material. By setting the marking ring, the staff can intuitively observe the distance the cable penetrates into the connector body, thereby facilitating the observation of whether the cable and terminal joint are properly connected to the connector body. This avoids misjudgment or incorrect judgment when the operator is fatigued or inattentive.

[0007] Furthermore, the auxiliary mechanism includes two mounting frames sleeved on the outer surface of the connector body, and a connecting rod slidably connected to the two mounting frames. By setting the mounting frames and connecting rod, the auxiliary mechanism can be installed on the outside of the connector body as needed, and the subsequent components can assist in inserting cables and terminal connectors into the connector body, making the operation of inserting cables and terminal connectors into the connector body more convenient and precise.

[0008] Furthermore, a first telescopic spring is sleeved on the outer surface of the connecting rod between the two mounting frames. The first telescopic spring is used to pull the two mounting frames closer to each other. The upper and lower ends of the first telescopic spring are fixed to the mounting frames on the same side, respectively. By setting the first telescopic spring, it is easy to pull the two mounting frames closer together, so that when the two mounting frames are close to each other, they are sleeved on the outside of the connector body and the cable is guided by subsequent components.

[0009] Furthermore, the auxiliary mechanism also includes several crossbars fixedly connected to the outer surface of the mounting frame. The outer ends of the crossbars are fixedly connected to clamping plates. The auxiliary mechanism also includes a clamping guide assembly connected to the clamping plates. By setting the crossbars and clamping plates, the clamping guide assembly can be easily adjusted at the clamping plates, thereby enabling the clamping guide assembly to provide clamping, limiting and guiding functions for the cable when it is inserted into the connector body.

[0010] Furthermore, the clamping guide assembly includes an adjusting rod that slides with a pre-drilled hole on the upper surface of the clamping plate, and a connecting frame fixed to the lower end of the adjusting rod. The inner wall of the connecting frame is rotatably connected to a pulley for guiding the cable. By setting the clamping guide assembly, the connecting frame and pulley inside the clamping guide assembly can be clamped, which facilitates the pulley to contact the surface of the cable and guide the cable to slide.

[0011] Furthermore, the clamping guide assembly also includes a second telescopic spring sleeved on the outer surface of the adjusting rod. The upper and lower ends of the second telescopic spring are fixed to the adjusting rod and the clamping plate, respectively. By setting the clamping guide assembly and the second telescopic spring inside the clamping guide assembly, it is easy to pull the adjusting rod, thereby enabling the adjusting rod to pull the connecting frame and pulley to contact the cable.

[0012] Compared with the prior art, this terminal connector that prevents terminal misalignment has the following advantages:

[0013] 1. By setting a marking ring, this utility model can provide visual guidance to workers when inserting cables and terminal connectors into the connector body, thereby facilitating the accurate insertion of cables and terminal connectors into the connector body and avoiding improper connection between the terminal connectors and the connector body. Furthermore, the auxiliary mechanism can facilitate guidance when inserting cables into the connector body.

[0014] 2. By setting a marking ring, this utility model allows workers to visually observe the distance the cable penetrates into the connector body, thus facilitating the observation of whether the cable and terminal joint are properly connected to the connector body. This avoids misjudgment or incorrect judgment when operators are fatigued or inattentive. Attached Figure Description

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0021] As described in the background art, operators are prone to misjudgment or incorrect judgment when they are fatigued or inattentive. Detecting the terminal status at the back end is not considered process error prevention. If the detection method fails, there is a possibility of defective products being released. Therefore, this embodiment provides a terminal connector to prevent terminals from being misplaced. This device allows for the use of a permanent marking method on the surface of the wires, such as laser marking or inkjet printing, before assembling the wire harness. This ensures that the operator is visually reminded to complete the terminal assembly work as required, avoiding the release of defective products when the back end detection method fails. It also provides stable guidance for the wires during insertion.

[0022] See Figure 1 - Figure 4This embodiment proposes a terminal connector to prevent terminal misalignment, including a connector body 1, a terminal connector 2 installed inside the connector body 1, a cable 3 connected to the terminal connector 2 on the outside of the connector body 1, a marking ring 4 on the outer surface of the cable 3, and an auxiliary mechanism 5 for guiding the cable 3 on the outside of the connector body 1.

[0023] refer to Figures 1 to 4 The marking ring 4 can be set in a way that can be permanently marked on the surface of the cable 3, such as by laser marking or inkjet printing. Before marking the marking ring 4, the cable 3 needs to be inserted into the connector body 1 through the terminal connector 2. The distance of the cable 3 into the connector body 1 is recorded when the terminal is connected in place. Then, the marking ring 4 is marked on the surface of the cable 3 by laser marking or inkjet printing to facilitate the subsequent connection and assembly of the cable 3 and the terminal connector 2 to the connector body 1.

[0024] The marking ring 4 can be permanently marked on the surface of the cable 3, such as by laser marking or inkjet printing. The choice of this step varies depending on the material of the cable 3. By setting the marking ring 4, the staff can intuitively observe the distance of the cable 3 into the connector body 1, thereby making it easier to observe whether the cable 3 and the terminal connector 2 are properly connected to the connector body 1, and avoiding misjudgment or incorrect judgment when the operator is fatigued or inattentive.

[0025] As a supplement, the marking ring 4 can only be a complete ring shape, so that the position of the marking ring 4 on the cable 3 can be easily observed from different directions, thereby enabling observation of whether the cable 3 and the terminal joint 2 are connected to the connector body 1.

[0026] The auxiliary mechanism 5 includes two mounting frames 501 sleeved on the outer surface of the connector body 1, and a connecting rod 502 slidably connected to the two mounting frames 501.

[0027] By setting the mounting frame 501 and the connecting rod 502, the auxiliary mechanism 5 can be installed on the outside of the connector body 1 as needed, and the auxiliary cable 3 and terminal connector 2 can be inserted into the connector body 1 through subsequent components, making the operation of inserting the cable 3 and terminal connector 2 into the connector body 1 more convenient and precise.

[0028] As a supplement, the mounting frame 501 and the connecting rod 502 can be installed to the outside of the connector body 1 via subsequent components, and facilitate the disassembly of the auxiliary mechanism 5.

[0029] A first telescopic spring 503 is sleeved on the outer surface of the connecting rod 502 and located between the two mounting frames 501. The first telescopic spring 503 is used to pull the two mounting frames 501 closer to each other. The upper and lower ends of the first telescopic spring 503 are respectively fixed to the mounting frames 501 on the same side.

[0030] By setting the first telescopic spring 503, it is easy to pull the two mounting frames 501 closer together, so that when the two mounting frames 501 are close to each other, they can be sleeved on the outside of the connector body 1, and the cable 3 can be guided by subsequent components.

[0031] As a supplement, the first telescopic spring 503 enables the two mounting frames 501 to be elastically pulled by the first telescopic spring 503, so that the mounting frames 501 are fitted onto the outside of the connector body 1, thereby enabling the auxiliary mechanism 5 to be fitted onto the outside of the connector body 1 to guide the cable 3.

[0032] The auxiliary mechanism 5 also includes a number of crossbars 504 fixedly connected to the outer surface of the mounting frame 501. The outer ends of the crossbars 504 are fixedly connected to clamping plates 505. The auxiliary mechanism 5 also includes a clamping guide assembly connected to the clamping plates 505.

[0033] By setting the crossbar 504 and the clamping plate 505, the clamping guide assembly can be easily adjusted at the clamping plate 505, thereby enabling the clamping guide assembly to provide clamping, limiting and guiding function for the cable 3 when it is inserted into the connector body 1, and making the cable 3 more stable when inserted into the connector body 1 to avoid tipping over and making it difficult to see the marking ring 4.

[0034] The clamping guide assembly includes an adjusting rod 506 that slides in conjunction with a pre-drilled hole on the upper surface of the clamping plate 505, and a connecting frame 508 fixed to the lower end of the adjusting rod 506. The inner wall of the connecting frame 508 is rotatably connected to a pulley 509 for guiding the cable 3.

[0035] By setting up a clamping guide component, the connection frame 508 and pulley 509 inside the clamping guide component can be set up to facilitate the pulley 509 to contact the surface of the cable 3 and guide the cable 3 to slide.

[0036] Furthermore, it provides a certain degree of stability and smoothness when the cable 3 is inserted into the connector body 1, preventing the marking ring 4 from shifting and affecting the operator's visual observation when the cable 3 and terminal connector 2 are inserted into the connector body 1.

[0037] The clamping guide assembly also includes a second telescopic spring 507 sleeved on the outer surface of the adjusting rod 506, with the upper and lower ends of the second telescopic spring 507 fixed to the adjusting rod 506 and the clamping plate 505, respectively.

[0038] By setting up a clamping guide assembly and the second telescopic spring 507 inside the clamping guide assembly, it is easy to pull the adjusting rod 506, so that the adjusting rod 506 can pull the connecting frame 508 and the pulley 509 to contact the cable 3, thereby clamping and guiding the cable 3 to slide, reducing the situation where the marking ring 4 bends on the surface of the cable 3 when the cable 3 is inserted into the connector body 1, which affects the operator's observation.

[0039] Working principle: When assembling wires and terminals with connectors, an initial distance test is required based on the cable 3. After the cable 3 and connector 2 are inserted into the connector body 1, the distance the cable 3 penetrates into the connector body 1 is recorded, and a marking ring 4 is made, ensuring that the connector 2 and connector body 1 are properly connected. In subsequent production lines, based on the data from the initial distance test, a permanent marking method can be used, such as laser marking or inkjet printing, to mark the surface of the cable 3 with the marking ring 4. This facilitates visual observation when the cable 3 and connector 2 are subsequently inserted into the connector body 1, ensuring the accuracy of the subsequent connection and assembly of the cable 3 and connector 2 and preventing incomplete connection after insertion.

[0040] When the cable 3 and terminal connector 2 are inserted into the connector body 1, they are guided by the pulley 509, which makes it easier for the cable 3 to be inserted into the connector body 1, and the auxiliary mechanism 5 can be installed or removed as needed.
