Description

Technical Field

[0001] The utility model relates to the field of hardware processing, in particular to a terminal anti-sinking structure. Background Art

[0002] When assembling the motor end cover, it is necessary to weld the leads on the motor terminals. When welding the leads, due to the high welding temperature or the long welding time, the motor end cover will undergo a certain amount of deformation. Although the deformation is not large, since the terminal passes through the end cover, the deformation of the end cover will cause perforation deformation, which will cause the terminal to sink easily, and then cause the terminal to not pass through the end cover enough. Therefore, improvement is urgently needed. Utility Model Content

[0003] In order to reduce the situation where the terminal sinks due to the thermal deformation of the end cover, the utility model provides a terminal anti-sinking structure.

[0004] The utility model provides a terminal anti-sinking structure adopts the following technical solutions:

[0005] A terminal anti-sinking structure comprises an undercut arranged on a terminal side wall and a fastening member for supporting the undercut, wherein the fastening member is arranged on an end wall of a motor rear cover, the fastening member is directly opposite to the undercut, and the undercut part is pressed against the fastening member.

[0006] When the rear cover at the terminal is heated and the terminal tends to sink, the undercut is tightly pressed against the terminal, and the terminal supports the undercut, making it difficult for the undercut to slide down, thereby limiting the sinking of the terminal.

[0007] Preferably, the motor rear cover is provided with a through hole for the terminal to pass through, the through hole is adapted to the shape of the terminal passing through end, the undercut protrudes from the side wall of the terminal, and the end of the undercut closest to the motor rear cover abuts against the end wall of the motor rear cover.

[0008] The end of the undercut abuts against the rear cover of the motor, making it difficult for the undercut to sink from the through hole, further reducing the possibility of the terminal sinking.

[0009] Preferably, the side of the pressing member close to the terminal is an inclined slope, the undercut is pressed against the slope, and the inclined upper end of the slope extends toward the end wall of the motor end cover in a direction close to the terminal.

[0010] When the processing of the undercut has deviations, causing the undercut to be larger, smaller or tilted, the contact point between the undercut and the retaining member will change slightly accordingly. The setting of the inclined surface enables the retaining member to adapt to the processing deviation of the undercut.

[0011] Preferably, the abutting member is a conical platform integrally connected to the end cover.

[0012] The fastening piece has a certain thickness. When the undercut is pressed against the fastening piece, the thickness of the fastening piece can serve as a supporting basis for the undercut, thereby preventing the fastening piece from being damaged due to excessive force. The setting of the conical platform enables the other conical surfaces to support the inclined surface that is under force after the inclined surface that abuts against the undercut is under force, thereby preventing the fastening piece from being easily broken by the force.

[0013] Preferably, the abutting member is a frustum.

[0014] When there is a slight deviation in the processing of the undercut, resulting in the undercut and the terminal not being in a directly facing state, the undercut can still abut against the fastening piece.

[0015] Preferably, the undercut is in a triangular shape, one side of the undercut coincides with the side wall of the terminal, and the top corner of the undercut directly faces the side wall of the terminal and is pressed against the pressing member.

[0016] The triangle has the characteristic of stability. When the terminal tends to sink, the top corner of the undercut is pushed by the fastening member. Due to the existence of the stable triangular structure, the undercut is not easily deformed by force.

[0017] In summary, the utility model includes the following beneficial technical effects:

[0018] When the rear cover of the motor at the terminal is heated during welding and the terminal tends to sink, the undercut is tightly pressed against the terminal, and the terminal supports the undercut, making it difficult for the undercut to slide down, thereby limiting the sinking of the terminal.

[0022] The following is combined with Figure 1 as well as Figure 2 The utility model is described in further detail.

[0023] The utility model embodiment discloses a terminal anti-sinking structure.

[0024] Reference Figure 1 as well as Figure 2 A terminal anti-sinking structure includes an undercut 2 arranged on the side wall of the terminal 1 and a fastening member 3 for supporting the undercut 2. The fastening member 3 is arranged on the end wall of the motor rear cover 4. The fastening member 3 is opposite to the undercut 2, and the undercut 2 partially presses against the fastening member 3.

[0025] When the rear cover at the terminal 1 is heated and the terminal 1 tends to sink, since the undercut 2 is pressed against the terminal 1 , the terminal 1 supports the undercut 2 , making it difficult for the undercut 2 to slide down, thereby limiting the sinking of the terminal 1 .

[0026] Reference Figure 1 as well as Figure 2 In this embodiment, the motor back cover 4 is provided with a through hole 5 for the terminal 1 to pass through, the through hole 5 is adapted to the shape of the end of the terminal 1 to pass through, the undercut 2 protrudes from the side wall of the terminal 1, and the end of the undercut 2 closest to the motor back cover 4 abuts against the end wall of the motor back cover 4.

[0027] The end of the undercut 2 abuts against the motor rear cover 4 , making it difficult for the undercut 2 to sink from the through hole 5 , further reducing the possibility of the terminal 1 sinking.

[0028] Reference Figure 1 as well as Figure 2 In this embodiment, the side of the pressing member 3 close to the terminal 1 is an inclined slope, the undercut 2 is pressed against the slope, and the inclined upper end of the slope extends toward the end wall of the motor end cover in the direction close to the terminal 1.

[0029] When the processing deviation of the undercut 2 causes the undercut 2 to be larger, smaller or tilted, the contact point between the undercut 2 and the retaining member 3 will change slightly accordingly. The setting of the inclined surface enables the retaining member 3 to adapt to the processing deviation of the undercut 2.

[0030] Reference Figure 1 as well as Figure 2 In this embodiment, the abutting member 3 is a conical platform integrally connected to the end cover.

[0031] The fastening member 3 has a certain thickness. When the undercut 2 is pressed against the fastening member 3, the thickness of the fastening member 3 can serve as a supporting basis for the undercut 2, thereby preventing the fastening member 3 from being damaged due to excessive force. In addition, the setting of the conical platform enables the other conical surfaces to support the inclined surface that is under force after the inclined surface that abuts against the undercut 2 is under force, thereby preventing the fastening member 3 from being easily broken by the force.

[0032] Reference Figure 1 as well as Figure 2 In this embodiment, the abutting member 3 is a frustum.

[0033] When there is a slight deviation in the processing of the undercut 2 so that the undercut 2 and the terminal 1 are not in a directly facing state, the undercut 2 can still abut against the fastening member 3.

[0034] Reference Figure 1 as well as Figure 2 In this embodiment, the undercut 2 is triangular in shape, one side of the undercut 2 coincides with the side wall of the terminal 1 , and the top corner of the undercut 2 facing the side wall of the terminal 1 is pressed against the pressing member 3 .

[0035] The triangle has a stable characteristic. When the terminal 1 tends to sink, the top corner of the undercut 2 is pushed by the fastening member 3. Due to the existence of the stable triangular structure, the undercut 2 is not easily deformed by force.
