Detailed Implementation

[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0037] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0038] The protective box 100 according to a first aspect embodiment of the present invention is described below with reference to the accompanying drawings.

[0039] like Figure 1 , Figure 3 and Figure 7As shown, the protective box 100 according to the first aspect of the present invention is used to accommodate terminals connected to a wire harness. The protective box 100 is formed with a receiving cavity 11, and a placement position 111 for accommodating terminals is provided in the receiving cavity 11. A detection hole 12 is provided on the outer surface of the protective box 100, and the detection hole 12 is opposite to and communicates with the placement position 111. Therefore, after the terminals connected to the wire harness are placed into the placement position 111, the protective box 100 can provide good protection for the terminals. Furthermore, by providing the detection hole 12 on the outer surface of the protective box 100, which is opposite to and communicates with the placement position 111, during the detection of the wire harness, a detection device such as a test probe can directly extend into the placement position 111 through the detection hole 12, ensuring that the test probe can make close contact with the terminals. Thus, the protective box 100 can improve the detection accuracy and efficiency of the wire harness while protecting the terminals.

[0040] According to the first aspect of the present invention, the protective box 100 has a detection hole 12 on its outer surface that is opposite to and communicates with the placement position 111. During the detection of the wire harness, the detection device, such as the test needle, can be directly inserted into the placement position 111 through the detection hole 12, ensuring that the test needle can make close contact with the terminal. Thus, the protective box 100 can improve the detection accuracy and efficiency of the wire harness while protecting the terminal.

[0041] In some embodiments, such as Figures 4-6 As shown, the outer surface of the protective box 100 is provided with annular ribs 16 surrounding the outer periphery of the detection hole 12. Therefore, the annular ribs 16 can better guide the insertion of the test probe and maintain its position to prevent probe wobbling from affecting testing accuracy. Furthermore, the protruding annular ribs 16 serve as a prominent marker, allowing the testing operator to quickly determine the position of the detection hole 12, thereby improving testing efficiency. In a specific example, along the axial direction of the detection hole 12 away from it, the inner circumferential surface of the annular rib 16 extends obliquely away from the central axis of the detection hole 12. That is, the internal space of the annular rib 16 forms a frustum shape, and the opening at the end of the annular rib 16 away from the detection hole 12 is larger. This reduces the difficulty of inserting the test probe into the annular rib 16 during insertion into the detection hole 12, and the inner circumferential surface of the annular rib 16 can guide the test probe to move towards the central axis of the detection hole 12.

[0042] According to some embodiments of this utility model, such as Figure 1 and Figure 3As shown, multiple placement positions 111 are provided, and a partition 13 is provided between any two adjacent placement positions 111 to separate two placement positions 111 on opposite sides. Since each placement position 111 can accommodate one terminal, by providing multiple placement positions 111, the number of terminals that the protective box 100 can accommodate can be increased. That is, terminals of multiple wire harnesses can be placed in the same protective box 100, reducing the number of protective boxes 100 and thus lowering the usage cost. Furthermore, the partition 13 effectively prevents terminals in two adjacent placement positions 111 from contacting, thereby forming effective insulation and avoiding the risk of short circuits due to contact between the two terminals.

[0043] According to some embodiments of this utility model, multiple detection holes 12 are provided. When there is only one placement position 111, the multiple detection holes 12 communicate with the same placement position 111, allowing the terminals within the placement position 111 to be detected through the multiple detection holes 12, thus reducing the operational difficulty for testing personnel. When there are multiple placement positions 111, the multiple detection holes 12 can correspond one-to-one with the multiple placement positions 111, thereby allowing the terminals within the multiple placement positions 111 to be detected separately through the detection holes 12, thereby improving the detection efficiency of wire harnesses connected to multiple terminals within the protective box 100.

[0044] In some embodiments, multiple placement positions 111 and multiple detection holes 12 are provided, with the number of detection holes 12 being the same as the number of placement positions 111 and corresponding one-to-one. Therefore, by accommodating multiple terminals, the protective box 100 can effectively reduce the number of protective devices for the wire harness terminals. Furthermore, during the testing process, multiple test pins can be simultaneously inserted into multiple detection holes 12 to achieve synchronous testing of multiple terminals, thereby improving the testing efficiency of the wire harness.

[0045] According to some embodiments of this utility model, a limiting structure is provided on the placement position 111. The terminal includes a connecting tube and a connecting piece disposed on the connecting tube. The connecting tube is connected to a wire harness, and the wire harness is fixed by passing through the connecting tube. At least one of the connecting tube and the connecting piece is limited and engaged with the limiting structure. Specifically, the limiting structure can limit the connecting tube to maintain the terminal's position within the protective box 100; the limiting structure can limit the connecting piece to maintain the terminal's position within the protective box 100; or both the connecting tube and the connecting piece can be limited and engaged with the limiting structure simultaneously to maintain the terminal's position within the protective box 100. Therefore, the limiting structure can effectively restrict the terminal's freedom of movement relative to the placement position 111, thereby firmly fixing the terminal within the protective box 100 and preventing it from detaching, thus ensuring the protective effect of the protective box 100 on the terminal.

[0046] According to some embodiments of this utility model, the limiting structure includes a positioning block 141, and a connecting hole is formed on the connecting piece. The positioning block 141 is adapted to pass through the connecting hole. Thus, the positioning block 141 can effectively position the connecting piece within the placement position 111; that is, the positioning block 141 can provide an accurate positional marker for the placement of the terminal. Furthermore, the positioning block 141 can restrict the degree of freedom of movement of the connecting piece to ensure the stability of the terminal housed within the placement position 111.

[0047] According to some embodiments of this utility model, the connecting piece is U-shaped, and the positioning block 141 and the inner wall surface of the placement position 111 together define a first limiting space 142, which is U-shaped. That is, the shape of the first limiting space 142 is the same as the shape of the connecting piece. Specifically, the first limiting space 142 being U-shaped means that the projection of the first limiting space 142 on the reference plane is U-shaped, and the reference plane is perpendicular to a third direction. This improves the limiting effect of the first limiting space 142 on the connecting piece, preventing the terminal from coming out of the placement position 111, thereby ensuring the protective effect of the protective box 100 on the terminal.

[0048] It should be noted that this is only an example illustrating one type of shape of the connecting piece and the first limiting space 142, to facilitate understanding of the cooperation between the connecting piece and the first limiting space 142. In other embodiments, the connecting piece is annular, and the projection of the first limiting space 142 in a third direction is also annular, that is, the shape of the first limiting space 142 is the same as the shape of the connecting piece.

[0049] According to some embodiments of this utility model, the limiting structure includes two opposing claws 143, which together define a second limiting space 144, within which at least a portion of the connecting tube is located. Thus, the two claws 143 can effectively hold the portion of the connecting tube within the second limiting space 144, preventing the connecting tube from detaching. Specifically, each claw 143 has an elastic arm and a limiting protrusion. The elastic arm extends in a third direction, and the elastic protrusion is located on the side of the elastic arm facing the second limiting space 144 and at the free end of the elastic arm. During the process of placing the connecting tube into the second limiting space 144, the connecting tube, through the limiting protrusion, pushes the free end of the elastic arm to deform outward. After the connecting tube enters below the limiting protrusion, the elastic arm returns to its original deformation, causing the limiting protrusion to be positioned above the connecting tube, thereby limiting the connection tube.

[0050] In some specific embodiments, each placement position 111 is provided with a corresponding limiting structure to ensure the limiting effect on the terminals in each placement position 111.

[0051] According to some embodiments of this utility model, the protective box 100 includes a box body 1 and a cover 2. A receiving cavity 11 is formed within the box body 1. The cover 2 is switchably disposed on the box body 1 between an open state and a closed state to open or close the receiving cavity 11. A detection hole 12 is disposed on at least one of the box body 1 and the cover 2. That is, when the cover 2 is in the open state, the receiving cavity 11 is opened to facilitate placing the terminal into the placement position 111 of the receiving cavity 11 and to facilitate removing the terminal from the receiving cavity 11; when the cover 2 is in the closed state, the receiving cavity 11 is closed to prevent the terminal from falling out of the receiving cavity 11, thus stably holding the terminal within the receiving cavity 11. Therefore, by providing a cover 2 that can be switched between an open state and a closed state, the difficulty of placing or removing the terminal from the receiving cavity 11 can be reduced, thereby improving the ease of use of the protective box 100.

[0052] According to some embodiments of this utility model, when the cover 2 is in the closed state, the side facing the box 1 is a first side 21. A pressing block 22 is provided on the first side 21. In the closed state, at least a portion of the pressing block 22 is located within the placement position 111 and is adapted to abut against the terminal. That is, by providing the pressing block 22 on the first side 21, when the cover 2 is in the closed state and the receiving cavity 11 is closed, the pressing block 22 can press down on the terminal in the placement position 111, thereby effectively preventing the terminal in the placement position 111 from moving around, thus improving the reliability of the protective box 100 in protecting the terminal.

[0053] In one specific example, the cross-section of the pressure block 22 is cross-shaped. This increases the contact area between the pressure block 22 and the terminal, thereby improving the stability of the pressure block 22 in pressing the terminal. It should be noted that this is merely an example of one type of cross-section of the pressure block 22 and is not a limitation thereof. In other embodiments, the cross-section of the pressure block 22 can also be circular, square, triangular, etc.

[0054] According to some embodiments of this utility model, the detection hole 12 is provided on the housing 1, and the detection hole 12 and the pressure block 22 are located on opposite sides of the terminal and are directly opposite each other. That is, the pressure block 22 presses down on the part of the terminal opposite to the detection hole 12 from the side of the terminal away from the detection hole 12. Thus, the pressure block 22 can better fix the part of the terminal opposite to the detection hole 12, thereby avoiding misalignment between the terminal and the detection hole 12 that would affect the detection. In addition, the detection hole 12 and the pressure block 22 are located on opposite sides of the terminal, which can avoid the pressure block 22 interfering with the insertion of the test probe, so as to ensure that the test probe can be smoothly inserted into the detection hole 12 and contact the terminal, thereby improving the detection efficiency.

[0055] In some embodiments, the placement positions 111 are provided with a plurality of spaced-apart blocks arranged along the second direction, and the receiving cavity 11 is provided with a plurality of spacers 13. A spacer 13 is provided between any two adjacent placement positions 111, and the spacers 13 are positioned in the third direction (e.g., Figures 5-7 At least one of the opposite side surfaces of e3 shown is provided with a groove, the third direction being perpendicular to the first direction (e.g., Figure 3 and Figure 6 e1 as shown) and the second direction (as shown) Figure 3 and Figure 5 As shown in the figure, e2) is vertical. Due to the presence of the partition 13, the thickness of the box body 1 at the location of the partition 13 is greater than the thickness at the location of the placement position 111 in the third direction. Therefore, by providing grooves on the opposite sides of the partition 13 along the third direction, the overall thickness of the box body 1 can be made more uniform, thus reducing the difficulty of injection molding.

[0056] In some embodiments, at least one of the opposite side surfaces along a third direction of the outer peripheral wall of the receiving cavity 11 is provided with a groove. This ensures that the overall thickness of the box body 1 is more uniform, thereby reducing the difficulty of injection molding.

[0057] According to some embodiments of this utility model, the protective box 100 further includes a flexible connecting part 3, one end of the box body 1 is connected to the cover body 2 through the flexible connecting part 3, and the other end of the box body 1 is snapped into the cover body 2. By providing the flexible connecting part 3 between the box body 1 and the cover body 2, while ensuring the connection between the box body 1 and the cover body 2, the relative position of the box body 1 and the cover body 2 can be changed by the deformation of the flexible connecting part 3, thereby realizing the switching between the open and closed states of the cover body 2. Furthermore, the snap-fit ​​connection between the box body 1 and the cover body 2 can stably keep the cover body 2 in the closed state, thereby improving the protection effect of the protective box 100 on the terminals. Moreover, the snap-fit ​​connection structure is easy to disengage, reducing the difficulty of subsequently opening the cover body 2 to remove the terminals, thus improving the reliability of the protective box 100 while enhancing its ease of use.

[0058] According to some embodiments of this utility model, a flexible connecting part 3 is disposed at one end of the box body 1 in a first direction. At the end of the box body 1 away from the flexible connecting part 3, a plurality of first snap-fit ​​structures 15 are arranged at intervals along a second direction. At the end of the cover body 2 away from the flexible connecting part 3, a plurality of second snap-fit ​​structures 23 are arranged at intervals along a second direction. The plurality of first snap-fit ​​structures 15 and the plurality of second snap-fit ​​structures 23 are engaged in a one-to-one snap-fit ​​relationship, with the second direction perpendicular to the first direction. That is, one end of the box body 1 in the first direction is flexibly connected to the cover body 2 through the flexible connecting part 3, and the other end of the box body 1 in the first direction is engaged with the cover body 2 through the cooperation of the plurality of first snap-fit ​​structures 15 and the plurality of second snap-fit ​​structures 23. This effectively increases the number of snap-fit ​​positions between the cover body 2 and the box body 1 when the cover body 2 is in the closed state, thus stably keeping the cover body 2 in the closed state and improving the reliability of the protective terminal of the protective box 100.

[0059] In a specific example, such as Figure 3 and Figure 4 As shown, a portion of the multiple second snap-fit ​​structures 23 is a slot. Multiple placement positions 111 arranged along the second direction are formed within the receiving cavity 11. A partition 13 is provided between each adjacent placement position 111 to separate the terminals within the adjacent placement positions 111. The slot portion of the second snap-fit ​​structure 23 is located on the partition 13. Therefore, the space on the partition 13 can be fully utilized to accommodate the second snap-fit ​​structure 23.

[0060] According to some embodiments of this utility model, the box body 1 and the lid 2 are integrally formed. Therefore, the integrally formed structure not only ensures the structural and performance stability of the box body 1 and the lid 2, but also facilitates molding and simplifies manufacturing. Furthermore, it eliminates the need for assembly parts and connection processes used to connect the box body 1 and the lid 2, resulting in lower production costs and significantly improved assembly efficiency. This ensures the reliability of the connection between the box body 1 and the lid 2. Moreover, the integrally formed structure has higher overall strength and stability, and a longer lifespan. In a specific example, the protective box 100 is an integrally formed part.

[0061] According to some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the protective box 100 has an anti-slip structure on at least one outer side. Therefore, by providing the anti-slip structure, during the use of the protective box 100, such as when an operator holds the protective box 100 to perform line inspection, the anti-slip structure increases the contact friction, preventing the protective box 100 from slipping and improving inspection efficiency.

[0062] According to some embodiments of this utility model, the anti-slip structure includes multiple anti-slip grooves 24. By providing multiple anti-slip grooves 24, the outer surface of the protective box 100 with the anti-slip structure can form an uneven structure, thereby increasing contact friction and achieving anti-slip properties. Furthermore, by providing the anti-slip grooves 24, while ensuring the anti-slip effect, the material cost and weight of the protective box 100 can be reduced, and it is easier to mold, resulting in lower demolding difficulty after injection molding.

[0063] According to some embodiments of this utility model, the anti-slip structure and the detection hole 12 are located on opposite sides of the protective box 100. That is, the detection hole 12 is located on the side of the protective box 100 away from the anti-slip structure. It is understood that the operator's hand needs to contact the anti-slip structure; that is, the operator's hand needs to rest on the anti-slip structure. Therefore, by placing the detection hole 12 on the side of the protective box 100 away from the anti-slip structure, the operator's hand can be prevented from obstructing the detection hole 12, thus ensuring detection efficiency. Furthermore, by placing the anti-slip structure on the side of the protective box 100 away from the detection hole 12, more space can be provided for the anti-slip structure, that is, a larger area of ​​anti-slip structure can be provided, which can improve the anti-slip effect when the operator holds the protective box 100.

[0064] According to some embodiments of this utility model, the anti-slip structure includes multiple anti-slip grooves 24, and the anti-slip structure and the detection hole 12 are located on opposite sides of the protective box 100. Therefore, while ensuring the anti-slip effect, the material cost and weight of the protective box 100 can be reduced, and the operator's hands can be prevented from obstructing the detection hole 12, thus ensuring detection efficiency.

[0065] The outdoor unit of an air conditioner according to a second aspect of the present invention is described below with reference to the accompanying drawings.

[0066] An outdoor air conditioning unit according to a second aspect embodiment of the present invention includes: a power cord and a protective box 100. The power cord has terminals at its ends, which are housed in placement positions 111. The outer surface of the protective box 100 has a detection hole 12 that is opposite to and communicates with the placement positions 111. Therefore, during the testing of the power cord, a testing device, such as a test probe, can directly extend into the placement positions 111 through the detection hole 12, ensuring that the test probe can make close contact with the terminals of the power cord. This allows the protective box 100 to protect the terminals while improving the accuracy and efficiency of power cord testing.

[0067] According to the second aspect of the present invention, the outdoor unit of the air conditioner has a detection hole 12 on the outer surface of the protective box 100 that is opposite to and communicates with the placement position 111. During the detection of the power cord, the detection device, such as the test probe, can be directly inserted into the placement position 111 through the detection hole 12 to ensure that the test probe can make close contact with the terminal of the power cord, thereby improving the detection accuracy and efficiency of the power cord while protecting the terminal.

[0068] In a specific example, if the power cord of the outdoor unit of an air conditioner includes a neutral wire, a live wire, and a signal wire, the receiving cavity 11 has three placement positions 111, which are respectively used to accommodate the terminal connected to the neutral wire end, the terminal connected to the live wire end, and the terminal connected to the signal wire end. That is, multiple terminals of the power cord can be accommodated simultaneously by a single protective box 100, saving the number of protective boxes 100. Furthermore, during the subsequent connection process of the power cord, opening the protective box 100 allows all three terminals to be taken out and connected to the junction box of the outdoor unit of the air conditioner at the same time, reducing the number of steps for installers and improving the connection efficiency of the power cord.

[0069] An air conditioner according to a third aspect embodiment of the present invention will now be described with reference to the accompanying drawings.

[0070] An air conditioner according to a third aspect of the present invention includes: an outdoor unit.

[0071] According to the third aspect of the present invention, the air conditioner has a detection hole 12 on the outer surface of the protective box 100 that is opposite to and communicates with the placement position 111. During the detection of the power cord, the detection device, such as the test probe, can be directly inserted into the placement position 111 through the detection hole 12 to ensure that the test probe can make close contact with the terminal of the power cord. Thus, the protective box 100 can improve the detection accuracy and efficiency of the power cord while protecting the terminal.
