While the pin structure can meet certain application requirements, it cannot meet applications requiring a larger contact area. Utility Model Content

[0003] In view of this, this application provides a three-dimensional four-sided connected patch fuse holder to solve all or part of the technical problems described in the background section of this application.

[0006] The two electrode pads are horizontally positioned within the bottom pad location, forming two horizontal electrical connection planes at the bottom of the fuse holder; this helps to increase the electrical connection area.

[0007] Preferably, the electrode is also provided with a vertical locking head and two longitudinal locking heads; the vertical locking head is provided with a vertical locking hole; the base is provided with a vertical locking point; the vertical locking head is located on the end face of the base and the vertical locking point is located in the vertical locking hole; the two longitudinal locking heads are respectively locked on the left and right sides of the electrode position.

[0008] The two vertical clips form two vertical electrical connection planes on the two end faces of the fuse holder, which helps to improve electrical connection performance and increase connection reliability by matching the horizontal electrical connection plane.

[0009] The two longitudinal clamps form two vertical electrical connection planes on the left and right sides of the fuse holder, respectively; this helps to improve electrical connection performance and increase connection reliability by matching the horizontal electrical connection plane.

[0010] Thus, each electrode simultaneously has a bottom horizontal electrical connection plane, an end vertical electrical connection plane, and two side vertical electrical connection planes, forming a three-dimensional four-sided electrical connection structure in space.

[0011] Preferably, the fuse retaining ring includes a left ring body and a right ring body; the left ring body and the right ring body are respectively disposed on the left and right sides of the patch portion; the fuse mounting position is defined between the left ring body and the right ring body.

[0013] Preferably, the electrode position is provided with an outer limiting part and an inner limiting part; the bottom ends of the outer limiting part and the inner limiting part are tightly fitted to the inner and outer sides of the patch part.

[0014] Preferably, the base has a pyramidal structure and the electrode position has a cuboid structure.

[0015] Beneficial technical effects:

[0016] 1. The three-dimensional four-sided surface mount fuse holder disclosed in this application, by setting surface mount positions on the holder body and surface mount parts on the electrode plates, can be installed into the circuit to be protected by surface mount connection. This changes the electrical connection structure of the fuse holder from point contact to surface contact, which is beneficial to improving electrical connection performance and meeting the application requirements that require a larger contact area.

[0017] 2. This application constructs a three-dimensional four-sided electrical connection structure in space through a bottom horizontal electrical connection plane, an end vertical electrical connection plane, and two side vertical electrical connection planes; this helps to improve the electrical connection performance and structural reliability of the fuse holder.
