Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a switch housing structure and a switch structure. Background Art

[0002] As a control element, the micro switch often needs to cooperate with other elements to connect or disconnect signals or circuits. The existing micro switch structure usually includes a housing, components arranged in the housing, and conductive terminals exposed outside the housing. In order to prevent moisture, dust, pollutants, etc. in the external environment from corroding and damaging the conductive terminals, the micro switch needs to be potted at the weld of the conductive terminal after assembly. When potting a traditional micro switch, a potting sleeve is usually added to one side of the conductive terminal, and then glue is poured into the potting sleeve to achieve sealing. The traditional potting sleeve is often connected to the housing. However, the installation of the connector on the housing can easily lead to a reduction in the arrangement space of the components in the housing, or cause the housing wall to become thinner, reduce the strength and rigidity of the housing, and thus affect the stability and service life of the micro switch.

[0034] Embodiment 1

[0035] like Figure 1 and Figure 3As shown, this embodiment provides a switch housing structure, including: a substrate 1, a first housing 2, and a second housing 3, wherein the first housing 2 and the second housing 3 are respectively snapped onto two sides of the substrate 1; a first clamping member 4 is provided on one side of the substrate 1 close to the second housing 3, a second clamping member 5 is provided in the second housing 3, and the first clamping member 4 and the second clamping member 5 are snapped into each other.

[0036] In this embodiment, the switch housing structure is used for a plastic-sealed switch. The conductive connection device of the switch is arranged on one side of the substrate 1. The conductive terminal of the switch element is connected to the conductive connection device and penetrates the substrate 1 along the thickness direction of the substrate 1 and extends to the other side. The first housing 2 is engaged with one side of the substrate 1 to form a closed cavity. The closed cavity is used to seal the conductive connection device on one side of the substrate 1 to prevent moisture and dust from damaging the conductive connection device. The first clamping member 4 on the other side of the substrate 1 is engaged with the second clamping member 5 inside the second housing 3, so that the second housing 3 is engaged with the other side of the substrate 1 to form a potting container. The extended end of the conductive terminal is located in the potting container. The potting container can protect the conductive terminal from moisture, dust, pollutants, etc. in the external environment.

[0037] This embodiment optimizes the structure and connection method of the traditional switch housing, and provides matching clamping parts on the substrate 1 and in the second housing 3, so that the second housing 3 can be stably clamped on the substrate 1, thereby not occupying the internal space of the first housing 2, and at the same time avoiding the influence of the wall thickness of the first housing 2 by adding clamping parts on the first housing 2, thereby ensuring that there is enough space in the first housing to accommodate the switch element.

[0038] In this embodiment, the first shell 2 and the second shell 3 are respectively buckled on both sides of the substrate 1 to form two cavities, which are used to accommodate multiple switch elements on the substrate 1, and can effectively isolate the external environment and reduce damage to the switch elements by dust, moisture, etc.

[0039] The second housing 3 is filled with a sealant, and the sealant is sealed between the second housing 3 and the substrate 1. Figure 1 As shown, in this embodiment, the conductive terminal penetrates the substrate 1 along the thickness direction of the substrate 1 and extends into the second housing 3. The sealant is poured into the potting container formed by the second housing 3 and the other side of the substrate 1 to pot the conductive terminal to prevent moisture, dust, pollutants, etc. in the external environment from corroding and damaging the conductive terminal; at the same time, the joint between the first clamping member 4 and the second clamping member 5 is also potted with the sealant to improve the installation stability.

[0040] like Figure 1 As shown, the first clamping member 4 is a clamping slot. Figure 2As shown, the second clamping member 5 is a hook, which is clamped in the slot. In this embodiment, the substrate 1 and the second shell 3 are accurately positioned by the mutual cooperation between the slot and the hook, ensuring that the relative position between the two components is accurate. After the hook is inserted into the slot, due to the design of its shape and size, the locking force that can be generated prevents the connection between the substrate 1 and the second shell 3 from loosening.

[0041] like Figure 2 As shown, a connecting plate 6 is provided in the second housing 3, and the two ends of the connecting plate 6 are respectively connected to the two opposite side walls in the second housing 3, and the second clamping member 5 is located on the connecting plate 6. In this embodiment, the second clamping member 5 is mounted in the middle of the second housing 3 through the connecting plate 6, and the connecting plate 6 provides additional support and fixation to prevent the second clamping member 5 from moving or loosening inside the second housing 3, and can protect the second clamping member 5 from external impact and wear.

[0042] like Figure 2 As shown, a reinforcing plate 7 is provided on the inner side wall of the second housing 3 corresponding to the connecting plate 6. The reinforcing plate 7 is used to increase the strength of the connecting plate 6 so that it can withstand greater external forces and loads. In this embodiment, the reinforcing plate 7 is made of high-strength material, which can improve the rigidity and bending strength of the connecting plate, thereby ensuring the stability and reliability of the connection.

[0043] like Figure 2 As shown, the number of the first clamping parts 4 and the number of the second clamping parts 5 are two respectively, and one of the first clamping parts 4 is clamped with one of the second clamping parts 5. In this embodiment, the connection between the substrate 1 and the second shell 3 is achieved by two groups of clamping parts, and the two groups of clamping parts can balance the load so that the load is evenly distributed on the two groups of clamping parts, reduce the bearing pressure of a single clamping part, and improve the overall stability and reliability. The two groups of clamping parts can also improve the accuracy of the connection. The cooperation of the two first clamping parts 4 and the two second clamping parts 5 can ensure the positioning accuracy of the substrate 1 and the second shell 3 in the horizontal and vertical directions, and reduce errors and deviations.

[0044] Furthermore, the two first clamping members 4 are symmetrically arranged with respect to each other, and the two second clamping members 5 are symmetrically arranged with respect to each other.

[0045] According to the above technical means, the symmetrical arrangement of the two sets of clamping structures can disperse the force, improve the connection rigidity between the substrate 1 and the second shell 3, and make the connection part more firm.

[0048] In this embodiment, the first conductive terminal 8, the second conductive terminal 9 and the third conductive terminal 10 are respectively mounted on the substrate 1, and respectively penetrate the substrate 1 along the thickness direction of the substrate 1 and extend into the second housing 3. The first clamping member 4 on the substrate 1 is clamped with the second clamping member 5 inside the second housing 3, so that the second housing 3 and the substrate 1 are buckled to form a potting container for protecting the first conductive terminal 8, the second conductive terminal 9 and the third conductive terminal 10 from moisture, dust, pollutants, etc. in the external environment.

[0049] In this embodiment, the space is fully utilized. By respectively providing matching clamping parts on the substrate 1 and in the second shell 3, the second shell 3 can be stably clamped on the substrate 1 without occupying the internal space of the first shell 2, thereby avoiding that the addition of clamping parts on the first shell 2 affects the wall thickness of the first shell 2.

[0050] like Figure 1 As shown, it also includes a conductive connection device, which is used for conductive connection with the first conductive terminal 8, and the conductive connection device can switch between the second conductive terminal 9 and the third conductive terminal 10 to conduct the first conductive terminal 8 with the second conductive terminal 9 or the first conductive terminal 8 with the third conductive terminal 10 to realize the on and off control of the switch. In this embodiment, the conductive connection device is arranged on one side of the substrate 1, and is located in a closed cavity formed by the first shell 2 and one side of the substrate 1. The closed cavity can seal the conductive connection device to prevent water vapor and dust from damaging the conductive connection device.

[0051] like Figure 1 and Figure 3 As shown, the first conductive terminal 8, the second conductive terminal 9 and the third conductive terminal 10 are respectively connected with an external wire 11. The length of the first conductive terminal 8, the second conductive terminal 9 and the third conductive terminal 10 is smaller than the depth of the above-mentioned potting container, so that the connection between the three terminals and the external wire is located in the potting container. When the sealant is poured, the three terminals and their connection are sealed by the sealant to prevent water and moisture from entering, so as to protect the electrical performance of the switch circuit and the stability of the connection.
