Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire harness connector technology, and in particular to a multilayer wire harness connector with flame retardant and anti-aging properties. Background Technology
[0002] In automotive electrical systems, in order to achieve reliable connections between different wiring harnesses and electrical devices, workers typically use multilayer wiring harness connectors to connect the wiring harnesses in the automotive electrical system to achieve electrical connections and signal transmission. Existing multilayer wiring harness connectors usually consist of a multilayer wiring harness connector female end, a multilayer wiring harness connector female end, and a connecting clip.
[0003] For example, utility model application CN202120215406.7 discloses a wire harness connector, specifically including a protective structure, a connector structure, and a combined structure. The connector structure is installed inside the protective structure, and the combined structures are installed on both sides of the connector structure. The protective structure includes a protective top shell, a protective bottom shell, a snap fastener, a snap fastener base, and a wire groove. The protective bottom shell is installed at the bottom of the protective top shell. This utility model, by installing a protective structure on the outside of the connector structure, with the protective top and base connected by a snap fastener, and wire grooves on both sides of the protective structure, facilitates the installation and removal of the protective structure through the snap fastener, while also increasing the protection of the connector, thereby further protecting the wire interface. The combined structures on both sides of the connector structure, with one set of combined blocks connected to another set of combined bases through the snap fastener structure, allow for flexible combination of the number of connectors according to the number of wire harnesses, making it suitable for connecting different numbers of wire harnesses.
[0004] However, in terms of traditional multilayer wire harness connectors, in order to facilitate quick insertion and removal of the wire harness, multilayer wire harness connectors are usually fixed by a simple snap-fit structure. However, when multilayer wire harness connectors are in a high-frequency vibration environment or are subjected to external impact, the snap-fit structure is prone to mechanical fatigue due to repeated stress, which can cause the multilayer wire harness connector to loosen, affecting the electrical connection effect and making it inconvenient to use. Utility Model Content
[0005] In view of this, the present invention provides a flame-retardant and anti-aging multilayer wire harness connector, which has a connecting block that provides double protection for the multilayer wire harness connector. When the female end and the female end of the multilayer wire harness connector are spliced, the connecting bracket squeezes the connecting block, causing the connecting block to slide within the connecting block and compress the fixing spring. When the female end and the female end of the multilayer wire harness connector are fully spliced, the connecting block will reset with the rebound of the fixing spring, allowing the connecting block to insert into the connecting bracket to lock the female end and the female end of the multilayer wire harness connector a second time.
[0006] This utility model provides a multilayer wire harness connector with flame retardant and anti-aging properties, specifically including: a multilayer wire harness connector female end; a connection socket is provided on the inner side of the multilayer wire harness connector female end; a connection plug is inserted into the connection socket; a multilayer wire harness connector male end is fixedly connected to the outside of the connection plug; a set of wire harness bodies are provided on the outside of both the multilayer wire harness connector female end and the multilayer wire harness connector male end; a fixing bracket is fixedly connected to the top surface of the multilayer wire harness connector female end; a fixing block is fixedly connected to the top surface of the multilayer wire harness connector male end; the fixing block is engaged in the fixing bracket.
[0007] Optionally, the top surface of the female end of the multilayer wire harness connector is symmetrically and fixedly connected to two auxiliary guide frames; the ends of the two auxiliary guide frames are provided with rounded bevels; the top surface of the male end of the multilayer wire harness connector is symmetrically and fixedly connected to two auxiliary guide plates; the two auxiliary guide plates are respectively aligned with the positions of the two auxiliary guide frames.
[0008] Optionally, the external of the sub-end of the multi-layer wire harness connector is symmetrically fixedly connected to two connecting blocks; each of the two connecting blocks is slidably connected to a connecting card block; a fixing spring is fixedly connected to the bottom surface of each of the two connecting card blocks; the ends of the two fixing springs are respectively fixedly connected to the two connecting blocks; the external of the female end of the multi-layer wire harness connector is symmetrically fixedly connected to two connecting card holders; the two connecting card holders are respectively aligned with the positions of the two connecting card blocks.
[0009] Optionally, a set of first damping protrusions is fixedly connected to the outside of both connecting blocks; a set of second damping protrusions is symmetrically fixedly connected inside both connecting brackets.
[0010] Optionally, a fixing frame is fixedly connected to the outer side of the female end of the multilayer wire harness connector and the outer side of the male end of the multilayer wire harness connector; a set of guide sliders is symmetrically fixedly connected inside each of the two fixing frames; a set of connecting springs is fixedly connected to the top surface of each of the two sets of guide sliders; the ends of the two sets of connecting springs are respectively fixedly connected inside the two fixing frames; a positioning clamping frame is fixedly connected between each of the two sets of guide sliders; the two positioning clamping frames are respectively in contact with the outer wall of the two sets of wire harness bodies.
[0011] Optionally, a label holder is fixedly connected to the top surface of both the female end and the male end of the multilayer wire harness connector; a label sticker is affixed to the top surface of both label holders. Beneficial effects
[0012] In the process of assembling multilayer wire harness connectors, the connecting bracket presses against the connecting block as the female and male ends of the multilayer wire harness connector are spliced together. When the female and male ends are fully spliced, the connecting block returns to its original position with the rebound of the fixing spring, allowing the connecting block to insert into the connecting bracket for a secondary locking of the female and male ends of the multilayer wire harness connector, forming a double safety. Even if the fixing block deforms slightly due to vibration, the connecting block can still limit displacement. At the same time, since the connecting blocks are symmetrically arranged on both sides, they can be subjected to force synchronously when subjected to vibration, avoiding deformation or breakage of the block caused by stress concentration on one side, effectively improving the practicality of the multilayer wire harness connector.
[0013] By attaching different colored labels to the outside of the female and male ends of the multilayer wire harness connector, operators can quickly identify and distinguish the circuits with different functions, reduce wiring errors, and effectively improve the convenience of the multilayer wire harness connector.

Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts. Example 1
[0027] This utility model proposes a multilayer wire harness connector with flame retardant and anti-aging properties. Please refer to [reference needed]. Figures 1 to 8 Includes: female terminal 1 of multilayer wire harness connector;
[0028] A connection socket 103 is provided on the inner side of the female end 1 of the multilayer wire harness connector; a connection plug 104 is inserted into the connection socket 103; a multilayer wire harness connector male end 101 is fixedly connected to the outside of the connection plug 104; a set of wire harness bodies 102 are provided on the outside of both the female end 1 and the male end 101; a fixing bracket 109 is fixedly connected to the top surface of the female end 1; a fixing block 110 is fixedly connected to the top surface of the male end 1; the fixing block 110 is snapped into the fixing bracket 109.
[0029] The top surface of the female end 1 of the multilayer wire harness connector is symmetrically and fixedly connected to two auxiliary guide brackets 112; the ends of the two auxiliary guide brackets 112 are provided with rounded bevels; the top surface of the male end 101 of the multilayer wire harness connector is symmetrically and fixedly connected to two auxiliary guide plates 111; the two auxiliary guide plates 111 are respectively aligned with the positions of the two auxiliary guide brackets 112.
[0030] Two connecting blocks 113 are symmetrically fixedly connected to the outside of the multilayer wire harness connector sub-end 101; a connecting clip 114 is slidably connected inside each of the two connecting blocks 113; a fixing spring 116 is fixedly connected to the bottom surface of each of the two connecting clips 114; the ends of the two fixing springs 116 are respectively fixedly connected inside the two connecting blocks 113; two connecting brackets 117 are symmetrically fixedly connected to the outside of the multilayer wire harness connector female end 1; the two connecting brackets 117 are respectively aligned with the positions of the two connecting clips 114.
[0031] Both connecting blocks 114 are externally fixedly connected to a set of first damping protrusions 115; both connecting brackets 117 are internally fixedly connected to a set of second damping protrusions 118.
[0032] A fixing bracket 105 is fixedly connected to the outer side of the female end 1 and the outer side of the male end 101 of the multilayer wire harness connector. A set of guide sliders 106 is symmetrically fixedly connected inside the two fixing brackets 105. A set of connecting springs 107 is fixedly connected to the top surface of the two sets of guide sliders 106. The ends of the two sets of connecting springs 107 are respectively fixedly connected inside the two fixing brackets 105. A positioning clamping bracket 108 is fixedly connected between the two sets of guide sliders 106. The two positioning clamping brackets 108 are in contact with the outer walls of the two sets of wire harness bodies 102 respectively.
[0033] The specific usage and function of this embodiment: The outer shell and internal insulation layer of the multilayer wire harness connector female terminal 1 and multilayer wire harness connector female terminal 101 are usually made of flame-retardant materials, which have good flame-retardant properties. Both the multilayer wire harness connector female terminal 1 and multilayer wire harness connector female terminal 101 have an anti-oxidation layer inside, enhancing the multilayer wire harness's resistance to heat aging. During the splicing process of the multilayer wire harness connector female terminal 1 and multilayer wire harness connector female terminal 101, the multilayer wire harness connector female terminal 101 is inserted into the multilayer wire harness connector female terminal. Within 1 hour, the arc-shaped surface at the end of the auxiliary guide plate 111 and the chamfered arc at the end of the auxiliary guide bracket 112 guide the multi-layer wire harness connector sub-end 101, providing auxiliary docking for the multi-layer wire harness connector sub-end 101. During the splicing process of the multi-layer wire harness connector female end 1 and the multi-layer wire harness connector sub-end 101, the fixing bracket 109 and the fixing block 110 fix the multi-layer wire harness connector female end 1 and the multi-layer wire harness connector sub-end 101. At the same time, as the multi-layer wire harness connector female end 1 and the multi-layer wire harness... When the connector sub-end 101 is spliced, the connecting card holder 117 presses against the connecting card block 114, causing the connecting card block 114 to slide within the connecting block 113 and press against the fixing spring 116. When the multilayer wire harness connector female end 1 and the multilayer wire harness connector sub-end 101 are fully spliced, the connecting card block 114 will return to its original position with the rebound of the fixing spring 116, allowing the connecting card block 114 to insert into the connecting card holder 117 to perform a secondary locking of the multilayer wire harness connector female end 1 and the multilayer wire harness connector sub-end 101, through the first damping protrusion 11. The setting of the 5th and the second damping protrusion 118 can increase the friction between the connecting block 114 and the connecting bracket 117 to suppress the slight slippage generated during vibration. The setting of the positioning clamp 108 and the fixing bracket 105 can limit the wire harness body 102. At the same time, the elastic potential energy of the connecting spring 107 itself can make the positioning clamp 108 adapt to wire harness bodies 102 of different diameters, and can also make the positioning clamp 108 provide continuous pressure on the wire harness body 102 to prevent the wire harness body 102 from loosening.

[0034] Based on Example 1, please refer to Figures 1 to 3 It includes: a label holder 119 and a label sticker 120. A label holder 119 is fixedly connected to the top surface of the female end 1 of the multilayer wire harness connector and the top surface of the male end 101 of the multilayer wire harness connector; a label sticker 120 is pasted on the top surface of both label holders 119.
[0035] The specific usage and function of this embodiment: By attaching different colored identification stickers 120 to the outside of the female end 1 and the male end 101 of the multilayer wire harness connector, operators can quickly identify and distinguish the lines with different functions, thereby reducing the occurrence of wiring errors.
