Description

Technical Field

[0001] The utility model relates to the technical field of automobile cooling fans, in particular to a connector fixing and installing structure. Background Art

[0002] A fixed mounting structure is required to fix the connector on the automobile cooling fan, so as to facilitate the connection between the connector and the power supply control connector outside the automobile.

[0003] The patent authorization publication document with authorization announcement number CN104810697B discloses an electrical connector and its corresponding fixing device, wherein the electrical connector includes a long rigid body, the rigid body having an input portion, the input portion forming a pair of adjacent channels for accommodating corresponding insulated electrical cables, and the electrical connector also having a base located at the bottom of the input portion; the electrical connector cooperates with the fixing device; the fixing device includes a base plate, two opposing elastic fixing elements are provided on the base plate, and a fixing area is formed between the elastic fixing elements for accommodating the input portion of the electrical connector; the elastic fixing elements are provided with respective fixing structures, when the input portion is inserted into the fixing area, the fixing structures can be stretched open by the input portion of the electrical connector, when the input portion is inserted into the fixing area, the fixing structures can fix the input portion of the electrical connector in the fixing area, each elastic fixing element also has a support platform, the support surface of the support platform is higher than the base plate, for supporting the input portion of the electrical connector, and the base is located between the support platforms of the two elastic fixing elements. In addition, the electrical connector further comprises a pair of mutually parallel positioning rods extending from the base, the bottom plate between the elastic fixing elements is provided with a pair of openings, and the positioning rods of the electrical connector base are respectively inserted into the openings.

[0004] However, the aforementioned fixed installation structure of the connector still has the following disadvantages: the input portion is held in place by elastic fixing elements on both sides and then positioned using two positioning rods. However, since the connector is relatively tight when docked with the external connector, it needs to be shaken when inserted, and the same is possible when removed. Since the elastic fixing elements themselves are elastically deformable, the elastic fixing elements may deform during insertion or removal, which may cause the input portion to separate from between the elastic fixing elements. Therefore, the aforementioned fixed installation structure is not secure, especially since the outer contour of the input portion is circular, which makes the clamping force of the elastic fixing elements more unstable. In addition, the connector is relatively cumbersome to disassemble. To remove the connector, the input portion needs to be pulled out vertically from the base plate. Since the cooling fan is generally arranged vertically and the connector is fixed to the base plate of the cooling fan, there is not much space to directly remove the connector. Utility Model Content

[0005] The technical problem to be solved by the present utility model is to provide a plug fixing and installation structure, which can be better installed and disassembled, and is more firmly fixed.

[0006] To solve the above technical problem, the technical solution of the present utility model is: a plug fixing and installation structure for an electric cooling fan of a vehicle. The plug includes a plug body, and the plug body includes an installation section for accommodating an insulated wire. The plug fixing and installation structure further includes a base provided on the cooling fan. Two support plates are oppositely provided on the base, and an assembly area convenient for installing the installation section is formed between the two support plates. A sliding clamping plate is provided in the assembly area on the base. A slot gap is formed between the sliding clamping plate and the base. A connecting seat is provided at the bottom of the installation section, and a slot portion convenient for the sliding clamping plate to insert is provided on the connecting seat. A limiting structure for restricting the separation of the sliding clamping plate and the slot portion is further provided on the base.

[0007] As a preferred solution, the limiting structure includes a limiting elastic tongue plate elastically provided on the base. A lower limiting block is provided at the upper end of the limiting elastic tongue plate, and an upper limiting block cooperating with the lower limiting block is provided on the slot portion.

[0008] As a preferred solution, the first end of the limiting elastic tongue plate is connected to the base. The second end of the limiting elastic tongue plate is upturned and suspended. A hollow hole is provided on the base below the limiting elastic tongue plate. The first end is upstream of the second end. When the slot portion and the sliding clamping plate are inserted, they slide from the first end to the second end of the limiting elastic tongue plate.

[0009] As a preferred solution, the sliding clamping plate includes a connecting clamping plate portion. The upstream end and the downstream end of the connecting clamping plate portion are both connected to the base. Sliding clamping edges are provided on both sides of the connecting clamping plate portion. The slot gap is formed between the sliding clamping edges and the base. Two slots slidingly cooperating with the sliding clamping edges are provided on the slot portion, and a limiting block for limiting and cooperating with the upstream end portion of the sliding clamping edge is further provided in the slot.

[0010] As a preferred solution, limiting strips are further provided on the base outside each sliding clamping edge, and the two limiting strips are slidingly cooperating with the outer side surface of the slot portion.

[0011] As a preferred solution, an upper limiting structure for limiting the upper part of the installation section is further provided at the upper ends of the two support plates.

[0012] As a preferred solution, the upper limiting structure includes an upper limiting seat arranged on the inner side of the support plate and extending toward another support plate, and the upper limiting seat is provided with an arc-shaped surface adapted to the outer contour of the mounting section, and the upper limiting seat is in contact with the outer contour of the mounting section or a gap is provided.

[0013] As a preferred solution, the upstream end of the lower limit block and the downstream end of the upper limit block are respectively provided with guide inclined surfaces for convenient sliding fit, and the downstream end of the lower limit block and the upstream end of the upper limit block are respectively provided with limit end surfaces for mutual interference and limit fit.

[0014] After adopting the above technical solution, the effect of the utility model is as follows: since the plug fixing installation structure also includes a base arranged on the cooling fan, the base is provided with two support plates arranged opposite to each other, and an assembly area for facilitating the installation of the installation section is formed between the two support plates, a sliding card plate is provided on the base in the assembly area, and a card slot gap is formed between the sliding card plate and the base, a connecting seat is provided at the bottom of the installation section, and a slot portion for facilitating the insertion of the sliding card plate is provided on the connecting seat, and a limiting structure for limiting the separation of the sliding card plate and the slot portion is provided on the base. Therefore, the plug is directly slidably inserted and matched between the connecting seat and the slot portion on the base and the sliding card plate, and the separation of the two is limited by the limiting structure, so that it can be slidably installed and fixed firmly during assembly, and at the same time, it only needs to slide and withdraw the installation section during disassembly. Since the card slot gap is formed between the sliding card plate and the base, the installation direction of the installation section is not perpendicular to the plate surface of the cooling fan, so that the direction of withdrawal or insertion can avoid the radiators on both sides of the cooling fan, and installation and disassembly are also more convenient.

[0015] Since the limiting structure includes a limiting spring tongue plate elastically arranged on the base, a lower limiting block is arranged on the upper end of the limiting spring tongue plate, and an upper limiting block cooperating with the lower limiting block is arranged on the slot portion. When the slot portion and the sliding card plate are slidably inserted and matched, the elastic action of the limiting spring tongue plate causes the lower limiting block to move downward to avoid the upper limiting block. When the sliding assembly is in place, the upper limiting block and the lower limiting block can cooperate with each other to limit the slot portion from falling out.

[0016] Also, since the sliding clamping plate includes a connecting clamping plate portion, both the upstream end and the downstream end of the connecting clamping plate portion are connected to the base, so the connection and fixation of the sliding clamping plate are very firm, which can ensure sufficient strength for the connection between the slot portion and the sliding clamping plate. Sliding clamping edges are provided on both sides of the connecting clamping plate portion, and a slot gap is formed between the sliding clamping edges and the base. Two slots that are slidably engaged with the sliding clamping edges are provided on the slot portion, and a limiting block that is in limiting engagement with the upstream end portion of the sliding clamping edge is further provided in the slot. In this way, the limiting block and the upstream end portion cooperate with each other to further limit another sliding direction of the slot portion, thus ensuring that the connection position does not shift.

[0017] Also, on the base, limiting bars are provided on the outside of each sliding clamping edge. The two limiting bars are slidably engaged with the outer side surface of the slot portion. The limiting bars can further restrict both sides of the slot portion and also facilitate the smooth insertion of the slot portion into the sliding clamping plate.

[0018] Also, an upper limiting structure for limiting the upper part of the installation section is provided at the upper ends of the two support plates. The upper limiting structure includes an upper limiting seat provided on the inner side of the support plate and extending towards the other support plate. An arc surface adapted to the outer contour of the installation section is provided on the upper limiting seat. The upper limiting seat is in contact fit or has a gap with the outer contour of the installation section. In this way, the position of the installation section can be further restricted by the upper limiting seat, avoiding excessive shaking during the insertion or extraction of the connector plug, which may cause the disconnection of the slot portion and the sliding clamping plate, making its fixation more reliable. At the same time, since the installation section is slidably inserted and installed, the upper limiting seat does not hinder the fixed installation of the installation section, and the two support plates do not need to be made of elastic materials, so their strength can be higher, further ensuring the limiting effect of the upper limiting seat.

Detailed implementation manners

[0028] The present utility model will be further described in detail below through specific embodiments.

[0029] As Figures 1 to 7 shown, a fixing and installing structure of a plug 5 is used on an electric cooling fan of a vehicle. The plug 5 includes a plug body 51. The plug body 51 includes an installation section 52 for accommodating an insulated wire. A connection seat 53 is arranged at the bottom of the installation section 52. A slot part 54 is arranged on the connection seat 53. A limiting structure 7 for restricting the separation of the sliding clamping plate 6 and the slot part 54 is further arranged on the base 1.

[0030] The fixing and installing structure of the plug 5 further includes a base 1 arranged on the cooling fan, and the base 1 is arranged on the bottom plate 4 of the cooling fan.

[0031] Two opposite support plates 2 are arranged on the base 1. An assembly area convenient for installing the installation section 52 is formed between the two support plates 2. Reinforcing ribs are arranged on the outer side surface of the support plate 2 to increase the strength of the support plate 2.

[0032] A sliding clamping plate 6 is arranged in the assembly area on the base 1. A slot gap 63 is formed between the sliding clamping plate 6 and the base 1. In this embodiment, the sliding clamping plate 6 includes a connecting clamping plate part 61. The upstream end and the downstream end of the connecting clamping plate part 61 are both connected to the base 1. The plate surface of the sliding clamping plate 6 is parallel to the bottom plate 4 of the cooling fan. Sliding edge parts 62 are arranged on both sides of the connecting clamping plate part 61. The slot gap 63 is formed between the sliding edge parts 62 and the base 1. Two slots which are slidably matched with the sliding edge parts 62 are arranged on the slot part 54. A limit stop block 56 which is limitedly matched with the upstream end part of the sliding edge part 62 is further arranged in the slot.

[0033] On the base 1, limit bars 8 are also provided on the outside of each sliding card edge portion 62, and the two limit bars 8 are in sliding fit with the outer side surface of the slot portion 54.

[0034] The limiting structure 7 includes a limiting elastic tongue plate 71 elastically arranged on the base 1. A lower limiting block 72 is arranged at the upper end of the limiting elastic tongue plate 71, and an upper limiting block 55 matched with the lower limiting block 72 is arranged on the slot portion 54. The first end of the limiting elastic tongue plate 71 is connected to the base 1, the second end of the limiting elastic tongue plate 71 tilts upward and is arranged in a suspended manner. A hollow hole 73 is arranged on the base 1 below the limiting elastic tongue plate 71. The first end is upstream of the second end. When the slot portion 54 and the sliding card plate 6 are inserted, they slide from the first end to the second end of the limiting elastic tongue plate 71. Guide inclined surfaces for convenient sliding fit are respectively arranged at the upstream end of the lower limiting block 72 and the downstream end of the upper limiting block 55, and limiting end surfaces for mutual contact and limiting fit are respectively arranged at the downstream end of the lower limiting block 72 and the upstream end of the upper limiting block 55.

[0035] During installation, after the two slots on the slot portion 54 are aligned with the sliding card edge portion 62, they slide from the first end to the second end. When sliding, the slot portion 54 will downwardly press the limiting elastic tongue plate 71, so that the lower limiting block 72 descends to avoid the upper limiting block 55. When sliding in place, the limiting block 56 in the slot will be in limiting fit with the upstream end portion of the sliding card edge portion 62. At this time, the upper limiting block 55 and the lower limiting block 72 are also in limiting fit, so as to ensure the accurate and firm installation position of the slot portion 54. When it is necessary to pull out, only need to press the limiting elastic tongue plate 71 from both sides by hand or a tool to make the lower limiting block 72 descend, and then the connection plug 5 can be conveniently pulled out.

[0036] At the upper ends of the two support plates 2, an upper limiting structure for limiting the upper part of the installation section 52 is also provided. The upper limiting structure includes an upper limiting seat 3 arranged on the inner side of the support plate 2 and extending towards the other support plate 2. An arc surface adapted to the outer contour of the installation section 52 is arranged on the upper limiting seat 3. There is contact fit or a gap is provided between the upper limiting seat 3 and the outer contour of the installation section 52.

[0037] Certainly, in this embodiment, the upper limiting seats 3 are respectively arranged on the two support plates 2, and the upper limiting seats 3 can also be directly connected between the two support plates 2 to form an integral limiting seat.

[0038] The main purpose of the upper limiting structure is to limit the upper position of the connection plug 5 to prevent excessive shaking during the docking or pulling out of the connection plug 5, which may cause the separation of the slot portion 54 and the sliding card plate 6.

[0039] In summary, the above fixed installation structure of the connector 5 is more firmly fixed, can adapt to a greater degree of shaking during docking or unplugging, and the connector 5 can also be easily removed.

[0040] The above-described embodiments are only descriptions of the preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and modifications made to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
