[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0037] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment of this utility model, based on the above-mentioned problems existing in the prior art, an insulation withstand voltage test fixture for a household combustible gas detector is provided, comprising:

[0038] The fixture base 1 has a groove 11 for placing the household combustible gas detector A to be tested.

[0039] Spring pin 2 is embedded in fixture base 1, and the test end of spring pin 2 extends from the side wall of groove 11 into groove 11;

[0040] The abutting component 3 is disposed on the fixture base 1. The abutting component 3 is movably abutting against the household combustible gas detector A to be tested, so that the outer shell of the household combustible gas detector A to be tested contacts the spring pin 2.

[0041] Specifically, the current technology for manually testing the insulation withstand voltage of household combustible gas detectors is inefficient, and the accuracy and stability of the test results are difficult to guarantee due to human factors. Furthermore, there is currently no specific fixture for testing the insulation withstand voltage of household combustible gas detectors.

[0042] In this embodiment, an insulation withstand voltage test fixture designed specifically for household combustible gas detectors is innovatively provided. The fixture consists of a fixture base 1, a spring pin 2, and a contacting component 3. It can perform insulation withstand voltage tests on household combustible gas detectors and is suitable for quality inspection in the large-scale production of household combustible gas detectors, thereby improving testing efficiency.

[0043] During testing, the household combustible gas detector A under test is placed on the groove 11 of the fixture base 1. After placement, the outer casing of the household combustible gas detector A under test will contact the spring pin 2 extending from the side wall of the groove 11. The spring pin 2 can receive external test signals, thereby completing the insulation withstand voltage test.

[0044] Furthermore, the groove 11 has two sides configured as sidewalls with a certain structural strength and blocking function, which can provide a limiting function for the household combustible gas detector placed in the groove 11. At the same time, in conjunction with the abutment component 3, which is located on opposite sides of the household combustible gas detector along with the spring probe, the position of the household combustible gas detector is ensured to be fixed during the test, avoiding deviations in test results caused by shaking or displacement, and improving the accuracy of the test.

[0045] Furthermore, in terms of spatial structure, the groove 11, apart from the bottom wall, can be designed with only two side walls, with the remaining part not having a closed structure and remaining in an open state. This facilitates the insertion and removal of household combustible gas detectors, and the open design allows the fixture to adapt to detectors of various sizes, giving it wide versatility. Moreover, the abutment part 3 is movable, ensuring the stability of the detector while also flexibly adapting to detectors of different specifications, further enhancing the practicality and adaptability of the fixture.

[0046] In a preferred embodiment, the fixture base 1 includes:

[0047] Base plate 12;

[0048] The first limiting side plate 13 is formed by extending the first side edge of the base plate 12 along the first direction, and the spring pin 2 is embedded in the first limiting side plate 13.

[0049] The second limiting side plate 13 is formed by extending the second side edge of the base plate 12 along the first direction. The base plate 12, the first limiting side plate 13 and the second limiting side plate 13 are arranged perpendicularly to each other. The base plate 12, the first limiting side plate 13 and the second limiting side plate 13 form a groove 11.

[0050] In this embodiment, the first direction is vertically upward.

[0051] Specifically, in this embodiment, the fixture base 1 is composed of a base plate 12, a first limiting side plate 13, and a second limiting side plate 13. The first limiting side plate 13 and the second limiting side plate 13 have a certain structural strength and can limit the household combustible gas detector placed in the groove 11.

[0052] Moreover, since neither the opposite side of the first limiting side plate 13 nor the opposite side of the second limiting side plate 13 has a closed structure, this open design allows the fixture to be adapted to detectors of various sizes, giving it wide versatility and adaptability.

[0053] Of course, if sufficient space is left on the opposite side of the base plate 12 and the ejector pin design to accommodate detectors of various sizes, a closed structure can also be set on the opposite side of the first limiting side plate 13 and the opposite side of the second limiting side plate 13.

[0054] In a preferred embodiment, a terminal block (not shown in the figure) is mounted on the fixture base 1;

[0055] The spring pin 2 also includes a signal terminal, which is electrically connected to the terminal block via a signal line.

[0056] Specifically, in this embodiment, the wiring terminal can be electrically connected to the host computer to receive external test signals sent by the host computer.

[0057] Two spring-loaded pins 2 are provided, spaced apart. One of the two spring-loaded pins 2 is grounded, and the other is used to receive external test signals.

[0058] In a preferred embodiment, the signal end of the spring pin 2 extends out of the fixture base 1 on the side opposite to the groove 11.

[0059] It also includes: a protective cover 4, which has a clearance space corresponding to the spring pin 2, and the protective cover 4 is installed on the fixture base 1.

[0060] Specifically, considering that the signal end of the spring pin 2 will protrude from the fixture base 1, in order to prevent damage, in this embodiment, a protective cover 4 is provided to protect the spring pin 2.

[0061] Furthermore, a protrusion 41 extends from the protective cover 4, and a through hole is provided at the protrusion 41. A cover mounting part is provided on the first limiting side plate 13, and the cover mounting part adopts a slotted design so that the surface of the protective cover 4 is flush with the surface of the first limiting side plate 13 after installation. An installation groove is provided in the slot, which corresponds to the through hole on the protrusion.

[0062] During installation, align the protrusion 41 of the protective cover 4 with the cover mounting part on the first limiting side plate 13, and then use bolts or other first fasteners 61 to pass through the through holes on the protrusion of the protective cover 4 and place them in the mounting groove of the first limiting side plate 13, thereby achieving the fixed installation of the protective cover 4 and the fixture base 1.

[0063] In a preferred embodiment, the abutting component 3 includes:

[0064] The fixture fixing seat 31 is installed on the bottom wall of the groove 11 of the fixture base 1, and the fixture fixing seat 31 is provided with a first mounting hole;

[0065] The clamp 32 is installed in the first mounting hole.

[0066] Specifically, in this embodiment, the abutting component 3 consists of a clamp fixing seat 31 and a clamp 32. The clamp fixing seat 31 is generally rectangular and is fixedly installed on the jig base 1 by fasteners such as bolts. The clamp 32 is installed in the first mounting hole of the clamp fixing seat 31.

[0067] The clamp 32 includes a rotating rod 321, an adapter block 322, a connecting rod 323, and an abutment part 324. The rotating rod 321 can be installed in the first mounting hole on the clamp fixing seat 31 through a bearing. The outer ring of the bearing is fixedly connected to the first mounting hole and cooperates with the rotating rod 321. One end of the rotating rod 321 is rotatably connected to the adapter block 322 through a rotating mechanism. One end of the connecting rod 323 is fixed on the adapter block 322, and the abutment part 324 is installed at the end of the connecting rod 323.

[0068] When the rotating rod 321 rotates, since one end of the rotating rod 321 is rotatably connected to the adapter block 322, the rotating mechanism can adopt a gear and rack mechanism or a ball screw mechanism, which can convert the rotational motion of the rotating rod 321 into the linear motion of the adapter block 322, thereby driving the connecting rod 323 and the abutting part 324 at the end of the connecting rod 323 to move together to abut against the household combustible gas detector A to be tested.

[0069] It should be noted that the structure of the clamp 32 described above is only an example to illustrate the movement process when the clamp comes into contact with the household combustible gas detector A to be tested. In fact, the clamp 32 used in this utility model is a conventional clamp that is currently available on the market, and its structure and implementation principle are common knowledge and will not be described in detail here.

[0070] In a preferred embodiment, the fixture base 1 is provided with a through hole 5, and a second fastener 62 is provided in the through hole 5, and the second fastener 62 is provided with an external thread.

[0071] The clamp fixing seat 31 has a second mounting hole with a corresponding through hole, and the second mounting hole has an internal thread that matches the external thread.

[0072] Specifically, in this embodiment, a through hole 5 is provided on the base plate 12, and a second fastener 62 with external threads is installed in the through hole 5. The clamp fixing seat 31 is provided with a second mounting hole corresponding to the through hole 5, and an internal thread adapted to the external thread of the second fastener 62 is provided in the second mounting hole.

[0073] By passing the second fastener 62 sequentially through the through hole and the second mounting hole on the base plate 12 from the bottom of the fixture base 1, the fixture base 1 and the clamp fixing seat 31 can be fixedly connected.

[0074] Furthermore, the bottom of the base plate 12 is provided with clearance holes corresponding to the fasteners, so that the bolt head surface of the fasteners is flush with the bottom surface of the base plate 12 after installation. The through hole 5 is generally U-shaped and includes the aforementioned clearance holes.

[0075] In this embodiment, the second fastener 62 can be a hex socket head cap screw, which includes a shank and a head. The head of the hex socket head cap screw is round on the outside and concave hexagonal in the middle. The fixture fixing seat 31 and the jig base 1 are fixedly connected by the hex socket head cap screw. Of course, this is not the only option; other fixing methods can be used in other embodiments.

[0076] In a preferred embodiment, the through holes 5 include multiple sets, and the multiple sets of through holes 5 are arranged at intervals;

[0077] The clamp fixing seat 31 can be optionally disposed in a set of through holes 5 to change the setting position of the clamp fixing seat 31.

[0078] Specifically, in this embodiment, the base plate 12 has multiple sets of through holes 5, each set of through holes 5 consisting of two through holes 5, which are symmetrically distributed. Similarly, the clamp fixing seat 31 also has two second mounting holes, which are located on both sides of the bottom of the clamp fixing seat 31 to improve the installation stability of the clamp fixing seat 31.

[0079] Considering the limited range of extension of the contact part on the clamp 32, for detectors that are too large or too small, it may be necessary to adjust the position of the clamp fixing seat 31. In this case, it is only necessary to remove the fasteners such as hex socket head cap screws, move the clamp fixing seat 31 to the different sets of through holes on the base plate 12, and then re-fix it with the fasteners such as hex socket head cap screws. The whole process is simple and convenient.

[0080] Furthermore, the protective cover 4 and the fixture base 1 are made of insulating material to ensure the insulation performance of the fixture.

[0081] In a preferred embodiment, the fixture base 1 is made of glass fiber epoxy resin (FR-4).

[0082] In a preferred embodiment, the protective cover 4 is made of glass fiber epoxy resin.

[0083] Specifically, in this embodiment, both the protective cover 4 and the fixture base 1 are made of green FR-4, which is a composite material made of epoxy resin and fiberglass cloth.

[0084] The advantages or beneficial effects of adopting the above technical solution are as follows: The insulation withstand voltage test fixture of this utility model achieves insulation withstand voltage testing by contacting the housing of a household combustible gas detector with a spring pin; the groove design on the base of the fixture provides a placement space for the household combustible gas detector to be tested, and at the same time, with the abutment component, ensures that the position of the household combustible gas detector is fixed during the test, avoiding the impact of shaking or displacement on the test accuracy; in addition, the fixture can be adapted to the housings of household combustible gas detectors of different specifications, improving the versatility and applicability of the fixture.

[0085] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made using the content of this specification and illustrations should be included within the protection scope of the present utility model.
