However, the existing relay housings are prone to misalignment during assembly due to inaccurate positioning, which can affect the assembly speed and effect. The base plate and housing are also prone to misalignment during assembly, which can lead to glue leakage during the potting process, affecting the quality of the relay housing and even causing it to be scrapped. At the same time, it also results in high labor costs. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing relay housings are slow to assemble manually, resulting in poor assembly quality that affects the quality of the relay housing and may even lead to its scrapping.

[0005] To solve the above problems, this utility model provides a relay housing with a locking mechanism, including a base, a housing, and a locking mechanism. The housing is inserted into the side of the base, and locking grooves are provided on both opposite sides of the housing. A locking rod is provided at the locking groove. Both ends of the base are provided with connecting grooves. Two locking mechanisms are fixedly connected in the corresponding connecting grooves. One end of the locking mechanism is provided with a locking groove corresponding to the locking rod.

[0006] Furthermore, the locking mechanism includes a spring post and a snap-fit ​​component, with both ends of the spring post being fixedly connected to the snap-fit ​​component and the connecting groove, respectively.

[0007] Furthermore: the card slot is located at one end of the card connector.

[0008] Furthermore, one side of the snap-fit ​​component is provided with an adjustment surface for adjusting the snap-fit ​​component.

[0009] Furthermore: the housing is provided with positioning grooves on both other sides, and the base is provided with positioning plates corresponding to the positioning grooves, the positioning plates being inserted into the positioning grooves.

[0010] Furthermore: the positioning groove is a cuboid, and the width of the positioning groove is less than the thickness of the shell.

[0011] The advantages of this utility model compared with the prior art are as follows:

[0012] This patent, by setting a locking mechanism in conjunction with a locking groove and a snap-fit ​​rod, enables convenient and quick assembly and fixing of the housing and base. Furthermore, the positioning between the base and the housing is precise during the assembly process, effectively improving the assembly efficiency of the relay housing and the pass rate after assembly.

[0020] 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.

[0021] Combined with appendix Figure 1-4This utility model provides a relay housing with a locking mechanism, including a base 1, a housing 2, and a locking mechanism 3. The housing 2 is inserted into the side of the base 1, and locking grooves 21 are provided on both opposite sides of the housing 2. A snap-fit ​​rod 22 is provided at the locking groove 21. Both ends of the base 1 are provided with connecting grooves 11. Two locking mechanisms 3 are fixedly connected in the corresponding connecting grooves 11. The locking mechanism 3 includes a spring post 32 and a snap-fit ​​member 33. The two ends of the spring post 32 are respectively fixed to the snap-fit ​​member 33 and the connecting groove 11. The connection is fixed. The slot 31 is located at one end of the snap-fit ​​component 33. The snap-fit ​​component 33 has an adjustment surface 34 on one side for adjusting the snap-fit ​​component 33. When assembling the relay housing 2 and the base 1, first push the two snap-fit ​​components 33 to both sides to fit the housing 2 against the side of the base 1, and make the locking groove 21 and the snap-fit ​​component 33 correspond. Release the snap-fit ​​component 33. The snap-fit ​​component 33 rebounds under the action of the spring column 32. At this time, the snap-fit ​​rod 22 is inserted into the slot 31, and the assembly of the housing 2 and the base 1 can be completed.

[0022] Combined with appendix Figure 1 , 2 4. The housing 2 has positioning grooves 23 on both sides. The base 1 has positioning plates 12 corresponding to the positioning grooves 23. The positioning plates 12 are inserted into the positioning grooves 23. The positioning grooves 23 are cuboids and the width of the positioning grooves 23 is less than the thickness of the housing 2. This makes it easier for the positioning plates 12 to be inserted into the positioning grooves 23. The positioning grooves 23 limit the positioning of the positioning plates 12. When the housing 2 is attached to the base 1, the housing 2 can be held and aligned with the positioning plates 12 on the base 1. When they are close together, the positioning plates 12 enter the positioning grooves 23, and the positioning of the base 1 and the housing 2 can be completed quickly.

[0023] The working principle of this application is as follows:

[0024] When assembling the relay housing 2 and the base 1, first push the two snap-fit ​​pieces 33 to the sides to fit the housing 2 against the side of the base 1. When fitting the housing 2 against the base 1, hold the housing 2 and align it with the positioning plate 12 on the base 1. When close, make the positioning plate 12 enter the positioning groove 23, which can quickly complete the positioning of the base 1 and the housing 2, so that the locking groove 21 and the snap-fit ​​piece 33 are in the same position. Release the snap-fit ​​piece 33, and the snap-fit ​​piece 33 will rebound under the action of the spring column 32. At this time, the snap-fit ​​rod 22 is inserted into the snap-fit ​​groove 31, and the assembly of the housing 2 and the base 1 is completed.
