AI Technical Summary
Existing SMA connectors are prone to cracking of the die-cast base during the riveting process.
Multiple vertical raised lines are arranged in a ring on the lower outer wall surface of the upper die casting, and a notch is provided in the middle of the vertical raised lines. The vertical raised lines are arranged along the height direction of the upper die casting, and the upper and lower vertical raised lines are on the same horizontal line.
This reduces the interference between the upper and lower die castings during the riveting process, prevents the base from cracking, and ensures the stability of the riveting force between the upper and lower die castings.

Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of connector, especially relates to a SMA connector's upper die casting structure. BACKGROUND
[0002] SMA connector adopts threaded connection, has small volume, wide frequency band, reliable connection and the like advantages, is the most widely used radio frequency connector.
[0003] The SBM connector structure mainly includes upper die casting, base die casting and the middle sleeve insulator and crown spring, and the upper die casting and the base die casting are prone to cracking in the riveting process. The existing SMA connector has excessive hard interference in the riveting process, and is prone to cracking. Therefore, there is an urgent need for a new SMA connector upper die casting structure to solve the above problems. SUMMARY
[0004] The utility model discloses a SMA connector's upper die casting structure, to solve the technical problem of cracking when riveting of the existing connector.
[0005] The utility model discloses a SMA connector's upper die casting structure, to solve the technical problem of cracking when riveting of the existing connector.
[0006] Preferably, the vertical ridge protrusion is arranged along the height direction of the upper die casting.
[0007] Preferably, the upper vertical ridge protrusion and the lower vertical ridge protrusion are on the same horizontal line.
[0008] Compared with the prior art, the utility model has the advantages of:
[0009] The SMA connector's upper die casting structure has multiple vertical ridge protrusions arranged in a ring array on the outer wall surface of the lower part of the upper die casting, and the middle part of the vertical ridge protrusion is provided with a notch. The notch reduces the excessive interference amount of the upper die casting and the lower die casting in the riveting process, and prevents the base from cracking. By arranging the vertical ridge protrusion on the upper die casting, the vertical ridge interference points are concentrated on the upper surface and the lower surface of the lower part of the upper die casting, and the middle vertical ridge is cancelled. The vertical ridge proportion of the upper die casting is reduced, which ensures the stability of the riveting force of the upper and lower die castings and prevents cracking. BRIEF DESCRIPTION OF DRAWINGS
[0010] The utility model will be further described below in combination with the drawings and examples:
[0011] Fig. 1is an embodiment of the upper die casting structure of the SMA connector of the utility model, and is a split structure schematic view.
[0012] Fig. 2 is an embodiment of the upper die casting structure of the SMA connector of the utility model, and is a structure schematic view of an application state.
[0013] In the figure: 1, upper die casting; 2, lower die casting; 11, vertical ridge protrusion; 12, notch. DETAILED DESCRIPTION
[0014] This part will describe the specific embodiments of the utility model in detail, and the preferred embodiments of the utility model are shown in the drawings, and the drawings are used to supplement the description of the text part in the form of graphics, so that people can intuitively and visually understand each technical feature and the overall technical scheme of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.
[0015] As Figs. 1-2 shown, the utility model relates to an upper die casting structure of an SMA connector, which comprises an upper die casting, the upper die casting 1 is riveted and connected with a lower die casting 2, a plurality of vertical ridge protrusions 11 are arranged in a ring array on the outer wall surface of the lower part of the upper die casting 1, the middle part of the vertical ridge protrusion 11 is provided with a notch 12, the vertical ridge protrusion 11 is arranged along the height direction of the upper die casting 1, and the upper vertical ridge protrusion and the lower vertical ridge protrusion are on the same horizontal line.
[0016] The upper die casting structure of the SMA connector of the utility model is riveted and installed in the lower die casting 2 during use, wherein a plurality of vertical ridge protrusions 11 are arranged in a ring array on the outer wall surface of the lower part of the upper die casting 1, the middle part of the vertical ridge protrusion 11 is provided with a notch 12, the notch 12 reduces the problem that the interference amount of the upper die casting 1 and the lower die casting 2 is too large during riveting and that the base cracks, the vertical ridge protrusion 11 is arranged on the upper die casting, so that the vertical ridge interference points are only concentrated on the upper surface and the lower surface of the lower part of the upper die casting, the middle vertical ridge is cancelled, the proportion of the vertical ridge of the upper die casting is reduced, the riveting force of the upper and lower die castings is stabilized, and the cracking is prevented.
[0017] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range of ordinary skilled persons in the technical field without departing from the purpose of the utility model.
