Description

Technical Field

[0001] The utility model relates to the technical field of electrical components, in particular to a wiring terminal and a high-voltage connector equipped with the wiring terminal. Background Art

[0002] A wiring terminal is a connecting component used between a cable and an electrical appliance or a power source. The structure of the existing wiring terminal can refer to a Chinese patent with the publication number CN111786135A, which discloses a wing-opening type wiring terminal. The structure includes a crimping part. One end of the crimping part is provided with a mating part for connecting and fixing the end of the cable. The crimping part includes a bottom plate. A crimping position for placing the cable is arranged on the bottom plate. Crimping wings extend from both sides of the bottom plate. The crimping wings and the crimping position are integrally formed. Before the cable is crimped, it needs to be stripped. The conductor, inner insulation layer, shielding layer, and outer insulation layer are successively exposed at the stripping place. During crimping, the conductor part is placed on the crimping position, and the crimping wings are driven to bend and deform towards the middle of the crimping position to wrap the cable, thus completing the crimping. In order to protect the cable and optimize the performance of the cable, a shielding ring is assembled on the cable before crimping with the terminal to reduce the influence of external electromagnetic fields on the power source or the circuit. The shielding ring is sleeved and fixed outside the shielding layer.

[0003] The existing terminals generally only crimp one cable. If multiple terminals are connected to a power source or an electrical appliance, enough space needs to be reserved at the wiring part of the power source or the electrical appliance to set the insertion interface, resulting in a relatively large volume of the power source or the electrical appliance. For the structure of the existing terminal, if two or more cables want to be directly connected, due to the existence of the shielding ring, after the crimping wings are crimped, the two cables and the shielding rings outside the cables will be squeezed against each other to cause interference, resulting in its inability to be used normally or even failure. Therefore, in order to reduce the volume of the power source or the electrical appliance and achieve lightweight design, it is necessary to first solve the problem that the existing wiring terminal cannot crimp more than one cable. Summary of the Utility Model

[0004] Aiming at the disadvantage that when the existing terminal structure is connected to a cable equipped with a shielding ring, each terminal can only access one cable, resulting in the inability of the power source or the electrical appliance to reduce its volume and achieve lightweight design, the purpose of the utility model is to provide a wiring terminal that can access multiple cables and can reserve space for the assembly of shielding rings for the cables.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A cable wiring terminal includes a terminal body and a crimping part connected to the terminal body. The crimping part includes a bottom plate connected to the terminal body. At least two main crimping units that can be respectively used for crimping one cable are formed on the bottom plate. A separation structure is arranged between adjacent main crimping units.

[0007] With the above - mentioned solution, each terminal can be connected to at least two cables. The separation structure can distinguish each main crimping unit, and after crimping, there will be a gap between each cable to prevent the cables from being squeezed against each other, leaving a space that can accommodate the shielding ring. Therefore, with a cable wiring terminal in this solution, each terminal body can be connected to at least two cables equipped with shielding rings. By achieving crimping with one terminal body, it can reduce the volume of the power supply or electrical appliance. In this solution, the cable can be stripped in the middle and then, after being bent, placed on adjacent main crimping units for crimping respectively, eliminating the step of cutting the cable once, which can improve production efficiency.

[0008] Preferably, the separation structure includes a mating protrusion protruding on the base film between two adjacent main crimping units.

[0009] Preferably, the mating protrusion is formed by bending the base film.

[0010] With the above - mentioned solution, most of the base films of existing terminals are composed of flat plates and are processed by stamping. The mating protrusion in this solution can also be formed in one step by stamping without adding extra production steps. During processing, the stamping die acts on the bottom of the base film to form a concave structure, and a mating protrusion is formed on the other side of the base film corresponding to the concave structure.

[0011] Preferably, the main crimping unit includes a first crimping area for placing the conductor part of the cable and a first crimping wing corresponding to the first crimping area.

[0012] Preferably, an auxiliary crimping unit for increasing the crimping stability of the cable is provided at one end of the main crimping unit far from the terminal body.

[0013] Preferably, the auxiliary crimping unit includes a second crimping area formed by expanding and extending outward on the side of the first crimping area far from the terminal body for placing the insulating part of the cable and a second crimping wing corresponding to the second crimping area.

[0014] Preferably, one end of the first crimping wing and the second crimping wing are respectively fixed on the base film, and the other ends can be deformed and respectively limit the conductor part and the insulating part of the cable in the first crimping area and the second crimping area after deformation.

[0015] With the above - mentioned solution, the crimping part in this solution can crimp the conductor part and the insulating part of the cable respectively, and the second crimping area and the second crimping wing are used to further strengthen the binding effect on the cable, enhance the overall pulling force of the cable, and make it not easy to break away from the crimping part.

[0016] Preferably, a fastening structure for enhancing the pulling force of the cable is provided on the auxiliary crimping unit. The fastening structure includes V-shaped notches spaced apart at the second crimping area and the second crimping wing on the bottom plate. The tips of the V-shaped notches face the terminal body, and fixing flaps that can be folded inward are formed at the V-shaped notches.

[0017] Preferably, at least two V-shaped notches are spaced apart on each group of auxiliary crimping units.

[0018] With the above solution, after the cable is crimped, its insulating part faces the V-shaped notch. At this time, the fixing flap can be squeezed inward from the outside of the second crimping area to drive it to fold inward. The tip of the fixing flap is in the shape of a barb and buckles into the insulating part. At this time, the fixing flap can effectively resist the pulling force on the cable, achieving the effect of enhancing the overall pulling force of the cable.

[0019] The second object of the present utility model is to provide a high-voltage connector, including the wiring terminal described in any one of the above solutions.

[0020] With the above solution, since the above wiring terminal can crimp more than two cables at the same time, when the high-voltage connector adopts this wiring terminal, the number of cable connections can be increased without changing the number of terminal interfaces, achieving the effect of saving space.

[0021] Due to the adoption of the above technical solutions, the present utility model has significant technical effects: each terminal can connect at least two cables. The separation structure can distinguish each first crimping area, and there will be a gap between each cable after crimping to prevent the cables from squeezing each other, leaving a space for accommodating the shielding ring. Therefore, by using a cable wiring terminal in this solution, each terminal body can connect at least two cables equipped with shielding rings, achieving the effect of reducing the volume of the power supply or electrical appliance when one terminal body is crimped; in this solution, the cable can be stripped in the middle and then placed on adjacent first crimping areas for crimping after being bent, saving the step of cutting the cable once and improving production efficiency.

In this embodiment, the main crimping unit 3 includes a first crimping area 31 for placing the conductor part of the cable and a first crimping wing 32 corresponding to the first crimping area 31. In this embodiment, the first crimping wing 32 extends and protrudes from both sides of the base film 2, and one end of the first crimping wing 32 away from the base film 2 can be deformed, and after deformation, the conductor part of the cable is limited in the first crimping area 31; a separation structure is provided between the two first crimping areas 31. The separation structure includes a matching protrusion 4 protruding on the base film 2 between the two first crimping areas 31. According to Figure 1 , 2 shown, in this embodiment, the matching protrusion 4 is formed by bending the base film 2, and a concave structure 41 corresponding to the matching protrusion 4 is formed on the side of the base film 2 facing away from the matching protrusion 4.

[0032] Combined with the above structure, referring to Figures 1 - 2 it can be known that each terminal in this embodiment can connect at least two cables. The separation structure can distinguish each first crimping area 31, and there will be a gap between each cable after crimping, preventing the cables from being squeezed against each other, and leaving a space that can accommodate the shielding ring. Therefore, by using a cable wiring terminal in this solution, each terminal body 1 can be connected to at least two cables equipped with shielding rings, achieving the effect that one terminal body 1 can be crimped to reduce the volume of the power supply or the electrical appliance;

[0033] In this embodiment, the cable can be stripped in the middle, and after being bent, it can be respectively placed on the adjacent first crimping area 31 for crimping, eliminating the step of cutting the cable once, and improving the production efficiency.

[0034] Embodiment 2

[0035] Based on Embodiment 1, this embodiment further defines a wiring terminal.

As shown in Figure 3 、 4 , the auxiliary crimping unit 5 includes a second crimping area 51 formed by expanding and extending outward on the side of the first crimping area 31 away from the terminal body 1 for placing the insulating part of the cable. A second crimping wing 52 corresponding to the second crimping area 51 is provided on the bottom plate 2. In this embodiment, the second crimping wing 52 extends and protrudes on both sides of the bottom plate 2 where the second crimping area 51 is located. The end of the second crimping wing 52 away from the bottom plate 2 can be deformed and, after deformation, limit the insulating part of the cable within the second crimping area 51. In this embodiment, the second crimping wing 7 extends and protrudes at the edges of both sides of the bottom plate 2 where the second crimping area 32 is located.

[0036] The crimping part in this solution can crimp the conductor part and the insulating part on the cable respectively. The functions of the second crimping area 32 and the second crimping wing 7 are to further strengthen the binding effect on the cable, enhance the overall pulling force of the cable, and make it not easy to break away from the crimping part.

The fastening structure includes V-shaped notches 6 spaced apart on the bottom plate 2 at the second crimping area 51 and the second crimping wing 52. The tip of the V-shaped notch 6 faces the terminal body 1. A fixing flap 7 that can be turned inward is formed at the V-shaped notch 6. In this embodiment, at least two V-shaped notches 6 are spaced apart on each auxiliary crimping unit 5.

[0039] After the cable is crimped, its insulating part faces the V-shaped notch 8. At this time, the fixing flap 9 can be squeezed inward from the outside of the second crimping area 51 to drive it to turn inward. The tip of the fixing flap 9 is barbed and buckles into the insulating part. At this time, the fixing flap 9 can effectively resist the pulling force on the cable, achieving the effect of enhancing the overall pulling force of the cable.
