Abstract
Description
Technical Field
[0001] This application relates to the field of connectors, and more particularly to a terminal housing for a washing machine. Background Technology
[0002] When the washing machine is running, it needs to use a connector for signal transmission. One end of the connector is inserted into the terminal socket of the washing machine, and the other end is inserted into the power supply terminal.
[0003] Existing terminal housings for washing machines typically use a snap-fit structure when connecting to the terminal socket of the washing machine. This improves the ease of assembly and disassembly. However, the snap-fit structure only achieves the effect of preventing detachment and cannot completely fix the connection. During the use of the washing machine, due to external factors such as shaking, the terminal connection may move relative to each other, resulting in unstable connection. Utility Model Content
[0004] In order to solve the technical problem that external shaking causes displacement of the terminal connection, resulting in unstable connection, in the prior art, this application provides a terminal housing for a washing machine.
[0005] This application provides a terminal housing for a washing machine, which adopts the following technical solution:
[0006] A terminal housing for a washing machine includes a terminal body, a positioning boss, and an inner locking structure. The positioning boss is disposed on the terminal body, and the inner locking structure includes a hook disposed on the terminal body for snap-fit connection with the terminal socket of the washing machine.
[0007] By adopting the above technical solution, the positioning boss ensures that when the terminal body is connected to the terminal socket of the washing machine, the side wall of the positioning boss abuts against the side wall of the terminal socket, preventing the terminal body from being over-inserted into the terminal socket. Simultaneously, the hook engages with the terminal socket, preventing detachment. The positioning boss and the internal locking structure work together to limit the terminal body's movement, preventing both over-insertion and detachment. During washing machine use, if shaking occurs, the positioning boss and internal locking structure reduce the possibility of relative movement between the terminal body and the terminal socket, improving the stability of the terminal connection.
[0008] Optionally, one end of the terminal body for inserting the power supply terminal is a wire terminal connection end, and one end of the positioning boss extends to the wire terminal connection end.
[0009] By adopting the above technical solution, the size of the positioning boss is maximized in the insertion direction, which strengthens the overall structural strength of the terminal and improves the durability of the terminal shell.
[0010] Optionally, one end of the terminal body for inserting the power supply terminal is a wire terminal connection end, and the other end of the terminal body for inserting into the terminal socket is a terminal socket connection end. The movable end of the hook is provided with a guide slope, and the distance between the guide slope and the terminal body decreases along the arrangement direction from the wire terminal connection end to the terminal socket connection end.
[0011] By adopting the above technical solution, when the terminal housing and the terminal socket are engaged, the guide slope abuts against the terminal socket and guides the movable end of the hook to swing, so as to facilitate the insertion of the inner locking structure into the terminal socket.
[0012] Optionally, the terminal body has multiple wiring channels, and the positioning boss has multiple corresponding wiring channels.
[0013] By adopting the above technical solution, multiple positioning bosses correspond one-to-one with the wiring channels, saving raw materials, achieving high structural strength, and being easy for operators to hold.
[0014] Optionally, one end of the terminal body used for inserting into the terminal socket is a terminal socket connection end, and a guide groove is provided on the terminal socket connection end. The size of the opening of the guide groove decreases along the arrangement direction from the guide groove to the wiring channel.
[0015] By adopting the above technical solution, the guide groove guides the terminal insertion into the terminal socket, making it convenient for operators to operate.
[0016] Optionally, one end of the terminal body used for inserting into the terminal socket is a terminal socket connection end, and the terminal socket connection end is provided with a foolproof protrusion.
[0017] By adopting the above technical solution, the foolproof boss prevents operators from inserting the terminal into the terminal socket in the wrong direction, thereby causing damage to the terminal or terminal socket.
[0018] Optionally, one end of the terminal body used for inserting into the terminal socket is the terminal socket connection end. The terminal body is provided with a barb. One end of the barb is fixed to the inner wall of the terminal body, and the other end of the barb extends out and is movable in the direction close to the terminal socket connection end. The barb is used for snap-fit connection with the wire terminal.
[0019] By adopting the above technical solution, the barb on the hook is connected to the wire terminal clip, which can prevent detachment and improve the connection stability.
[0020] Optionally, the movable end of the barb is provided with a barb bevel, the barb bevel facing the connection surface between the terminal body and the barb.
[0021] By adopting the above technical solution, the connection reliability is improved by using the beveled hook, and the possibility of the wire terminal slipping off the hook is reduced when shaking occurs.
[0022] Optionally, a limiting block is provided on the movable end of the barb, and the barb and the limiting block are arranged along the insertion direction of the wire terminal.
[0023] By adopting the above technical solution, the limit block prevents the barb from being completely embedded in the wire terminal, which reduces the height requirement of the barb's inclined surface to a certain extent, increases the tolerance value for barb manufacturing, and facilitates terminal production and processing.
[0024] Optionally, it also includes a wire terminal unlocking component. The terminal body has a countersunk hole and a through hole sequentially formed from the outside to the inside. One end of the wire terminal unlocking component extends into the terminal body through the countersunk hole and the through hole and is fixed with a barb. The other end of the wire terminal unlocking component extends into the countersunk hole.
[0025] By adopting the above technical solution, the fixing part of the wire terminal unlocking component is fixedly connected to the barb, which allows the operator to drive the barb to move outside the terminal body through the wire terminal unlocking component, thereby unlocking the wire terminal and facilitating the operator's operation.
[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] 1. When the terminal body is connected to the terminal socket of the washing machine, the positioning boss prevents the terminal body from being over-inserted into the terminal socket; at the same time, the hook prevents it from coming loose. The positioning boss and the internal locking structure work together to limit the position of the terminal body, reducing the possibility of relative movement between the terminal body and the terminal socket to a certain extent, and improving the stability of the terminal connection;
[0028] 2. The foolproof protrusion prevents operators from inserting the terminal into the terminal socket in the wrong direction, which could damage the terminal.
[0029] 3. The barb on the hook is connected to the wire terminal clip, which prevents it from coming loose and improves the stability of the connection. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0036] Example 1:
[0037] Reference Figure 1 Embodiment 1 of this application discloses a terminal housing for a washing machine, including a terminal body 1, a positioning boss 2, and an inner locking structure 3. One end of the terminal body 1 for inserting a power supply terminal is a wire terminal connection end 11, and the other end of the terminal body 1 for inserting into a terminal socket is a terminal socket connection end 12. The wire terminal connection end 11 and the terminal socket connection end 12 are distributed at both ends along the length of the terminal body 1.
[0038] Reference Figure 1 The length direction of the terminal body 1 is set to the front-to-back direction, the width direction of the terminal body 1 is set to the left-to-right direction, and the thickness direction of the terminal body 1 is set to the up-to-down direction. The positioning boss 2 is integrally formed on the lower side of the terminal body 1. There are two positioning bosses 2, and both positioning bosses 2 are arc-shaped. One end of the positioning boss 2 extends to the wire terminal connection end 11, and the other end of the positioning boss 2 is used to abut against the terminal socket.
[0039] Reference Figure 2 The terminal body 1 has two wiring channels 13, and the wiring channels 13 correspond one-to-one with the two positioning bosses 2. The terminal socket connection end 12 of the terminal body 1 has a guide groove 14, and the opening size of the guide groove 14 decreases along the arrangement direction from the guide groove 14 to the wiring channel 13.
[0040] Reference Figure 2Both wiring channels 13 are equipped with barbs 5. One end of the barb 5 is integrally formed on the inner wall of the terminal body 1, and the other end of the barb 5 is movable and extends outward along the direction close to the terminal socket connection end 12. The movable end of the barb 5 is provided with a barb bevel 51, which faces the connection surface between the terminal body 1 and the barb 5. The movable end of the barb 5 is provided with a limit block 52, and the barb 5 and the limit block 52 are arranged along the insertion direction of the wire terminal.
[0041] Reference Figure 1 The inner locking structure 3 includes a pair of mounting brackets 32 and a hook 31 for snap-fit connection with the terminal socket of the washing machine. The two mounting brackets 32 are L-shaped. One end of the two mounting brackets 32 is symmetrically distributed on the upper surface of the terminal body 1 along the left-right direction and is fixedly connected to the terminal body 1. The other end of the two mounting brackets 32 extends outward along the front-back direction near the terminal socket connection end 12. One end of the hook 31 is fixedly connected between the two mounting brackets 32. The other end of the hook 31 extends outward along the length direction of the terminal body 1 near the terminal socket connection end 12. The mounting brackets 32 and the hook 31 are integrally formed on the upper surface of the terminal body 1.
[0042] Reference Figure 2 The movable end of the hook 31 is provided with a guide slope 311, and the distance between the guide slope 311 and the terminal body 1 decreases along the arrangement direction from the wire terminal connection end 11 to the terminal socket connection end 12.
[0043] Reference Figure 1 The terminal body 1 is provided with a foolproof protrusion 4. The foolproof protrusion 4 is integrally formed on the lower ends of the left and right sides of the terminal body 1. The foolproof protrusion 4 is a cuboid structure. One end of the foolproof protrusion 4 is located at the terminal socket connection end 12 and is chamfered to facilitate the insertion of the terminal body 1 into the terminal socket. The other end of the foolproof protrusion 4 extends to fit against the positioning protrusion 2.
[0044] The implementation principle of Example 1 is as follows: When the terminal housing is connected, the power supply terminal of the wire terminal connection end 11 of the terminal body 1 is inserted, and the end of the wire terminal is snapped into place with the barbed bevel 51, completing the connection between the wire terminal and the terminal housing; the operator inserts the hook 31 and the terminal socket connection end 12 into the terminal socket by compressing the hook 31, and the hook 31 snaps into place with the terminal socket. The wire terminal in the terminal socket enters the wiring channel 13 through the guide groove 14 and contacts the wire terminal at the power source to complete the electrical connection. To unlock the terminal socket connection end 12, the terminal body 1 is pulled out of the terminal socket by squeezing the hook 31.
[0045] Example 2:
[0046] Reference Figure 3 and Figure 4The difference between this embodiment and Embodiment 1 is that the terminal housing also includes a wire terminal unlocking component 6. A countersunk hole 15 and a through hole 16 are sequentially formed from the outside to the inside on the lower end surface of the terminal body 1. The countersunk hole 15 is a square countersunk hole, and the through hole 16 is a circular through hole. The diameter of the through hole 16 is smaller than the width of the countersunk hole 15. The wire terminal unlocking component 6 includes a fixing part 61 and a handle part 62. The fixing part 61 is columnar, and the handle part 62 is disc-shaped. The fixing part 61 passes through the countersunk hole 15 and the through hole 16 and is threadedly connected to the movable end of the barb 5. The fixing part 61 is slidably disposed within the countersunk hole 15 and the through hole 16. The diameter of the handle part 62 is larger than the diameter of the through hole 16, and the diameter of the handle part 62 is smaller than the length of the countersunk hole 15. The thickness of the handle part 62 is not greater than the depth of the countersunk hole 15, thus preventing the handle part 62 from interfering with other components.
[0047] The implementation principle of Example 2 is as follows: When the wire terminal needs to be unlocked, the wire terminal unlocking component 6 is moved to the outside of the terminal body 1 to unlock the wire terminal and the barb 5, and the wire terminal is pulled out of the terminal body 1.
[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
