Referring to fig. 1, 2 and 5, a protector 10 according to an embodiment of the present disclosure includes a first portion 11 and a second portion 12. The first portion 11 is formed with a first cavity 111. The second portion 12 is connected to the first portion 11. The second portion 12 is formed with a second cavity 121. The second cavity 121 communicates with the first cavity 111. The cross-sectional profile of the second cavity 121 is non-circular. The first cavity 111 and the second cavity 121 are each configured to receive a portion of the conductive terminal 30.

In the protector 10 of the embodiment of the present application, the second cavity 121 accommodates part of the conductive terminal 30, and the cross-sectional profile of the second cavity 121 is non-circular, so that under the condition that the conductive terminal 30 is fixed, the second cavity 121 can limit the protector 10, thereby preventing the protector 10 from deforming, such as deflecting, relative to the conductive terminal 30, and preventing the conductive terminal 30 from being exposed easily and being rusted.

Specifically, the first portion 11 of the protector 10 is located at the upper portion of the protector 10, and the spatial shape of the first cavity 111 may be a square space. When the outer shape of the first cavity 111 is square, the edge of the square may be arc-shaped, and when the edge of the outer shape of the first portion 11 is arc-shaped, the outer edges of the first portion 11 are smooth and are not likely to affect objects around the first portion 11 of the protector 10.

The second portion 12 of the protector 10 is located directly below the opening of the first portion 11 of the protector 10 and is open adjacent to the first portion 11 of the protector 10. The second portion 12 may be connected to the first portion 11 in a partially connected manner. When the first portion 11 is partially connected to the second portion 12, the first portion 11 may be turned approximately 90 degrees along the connection. Therefore, when the fixed position of the conductive terminal 30 needs to be checked, the protection piece 10 does not need to be disassembled, and the conductive terminal 30 can be exposed by rotating the first part 11, so that the function of quick checking is achieved.

The second cavity 121 of the second part 12 and the first cavity 111 of the first part 11 may communicate on the same plane, and the cross-sectional profiles of the second cavity 121 and the first cavity 111 may be non-circular. When the cross-sectional profiles of the second cavity 121 and the first cavity 111 are non-circular, the cross-sectional profile of the second cavity 121 and the cross-sectional profile of the first cavity 111 may be rectangular or square. Since the cross section of the second cavity 121 has the same shape as the cross section of the first cavity 111, the flat structure 310 of the conductive terminal 30 can be better accommodated in the first cavity 111 and the second cavity 121 of the protector 10.

The protector 10, the first portion 11 of the protector 10, and the second portion 12 of the protector 10 may all be made of rubber. When the protector 10, the first portion 11 of the protector 10, and the second portion 12 of the protector 10 are made of rubber, the rubber may be selected from natural rubber, synthetic rubber, and the like.

Referring to fig. 1, 2, and 5, in some embodiments, the cross-sectional profile of the second cavity 121 is square.

As such, when the cross-sectional shape of the second cavity 121 is square, the cross-sectional shape of the second cavity 121 is the same as the shape of the flat structure 310 of the conductive terminal 30. Thus, the second cavity 121 is adapted to receive the flat structure 310 portion of the conductive terminal 30. In addition, the second cavity 121 can also partially mate with the flat structure 310 of the conductive terminal 30, which improves the integrity of the conductive terminal 30 and the protector 10. Also, the square profile of the second cavity 121 allows for a savings in material usage in the second portion 12 of the protector 10 over a round or otherwise shaped second cavity 121.

Specifically, while the cross-sectional shape profile of the second cavity 121 may be square, the square may be selected to be square or rectangular. When the cross-sectional profile of the second cavity 121 is square or rectangular, the corners of the square or rectangular shape may be curved.

Referring to fig. 1, 2, and 5, in some embodiments, the second portion 12 includes a first wall 122 and a second wall 123, the first wall 122 is opposite to the second wall 123, and the first cavity 111 has an opening 113 facing away from the second wall 123.

Thus, the first wall 122 and the second wall 123 of the second portion 12 are opposite to each other to form a space for accommodating the conductive terminal 30, and the second portion 12 can protect the conductive terminal 30 near the first wall 122 and the second wall 123, and the first wall 122 and the second wall 123 of the second portion 12 are opposite to each other to form a shape, so that the requirement for difficulty in molding a rubber structure can be reduced. Since the first cavity 111 has an opening 113 facing away from the second wall 123, the opening of the first cavity 111 is oriented to facilitate receiving the securing portion of the conductive terminal 30 and the rounded portion of the head of the snap bolt.

Specifically, the first wall 122 of the second part 12 is a rubber wall corresponding to the left side of the centerline of the second cavity 121 of the second part 12, and the second wall 123 of the second part 12 is a rubber wall corresponding to the right side of the centerline of the second cavity 121 of the second part 12. The plane of the first wall 122 is parallel to and opposite to the plane of the second wall 123. The opening 113 of the first cavity 111 has the same shape as the cross-sectional profile of the first cavity 111. Thus, the opening 113 of the first cavity 111 may be square, and the opening 113 of the first cavity 111 faces away from the plane of the second wall 123.

Referring to fig. 1, 5 and 8, in some embodiments, the first portion 11 protrudes from the second wall 123 away from the first wall 122, the first portion 11 further forms a slot 112 communicating with the first cavity 111, and the slot 112 is used for clamping an end of the fastener 20.

In this way, the protrusion of the first portion 11 from the second wall 123 increases the spatial volume of the first portion 11, and can effectively accommodate the card slot 112 of the first portion 11 communicating with the first cavity 111. The engaging groove 112 is connected to the first cavity 111, and when the end of the fastener 20 is engaged in the engaging groove 112, the relative position between the first portion 11 and the engaging groove 112 can be fixed, so as to improve the stability between the protection member 10 and the fastener 20.

Specifically, the slot 112 is primarily used for positioning the relative positions of the first portion 11 and the fastener 20. The fastener 20 is a type of mechanical part used for fastening connections. The projection of the first portion 11 away from the first wall 122 may be an extension along the cross-sectional profile of the first cavity 111. The shape of the slot 112 may be selected to be circular, and the depth of the slot 112 may be adjusted according to the thickness of the end of the fastener 20. The depth of the slot 112 may be selected to be greater than or equal to the thickness of the end of the fastener 20. The fastener 20 may be selected as a common fastening part, and the thickness of the end of the fastener 20 is largely determined by the head thickness of different bolts. The hexagonal head bolt can be adopted at the end of the fastener 20, the hexagonal head bolt has high mechanical performance, the wrench can be conveniently screwed, and the convex hexagonal head can be clamped with the clamping groove 112 better.

Referring to fig. 1, 3 and 5, in some embodiments, the protection member 10 includes a sealing ring 14, the sealing ring 14 is disposed around an edge of the first cavity 111, and the sealing ring 14 connects the first portion 11 and the first wall 122.

In this way, the sealing ring 14 is disposed at the edge of the first cavity 111, and mainly protects a portion of the conductive terminal 30 received in the first cavity 111. The sealing ring 14 can provide good sealing performance in the first cavity 111, improve corrosion resistance of the components inside the first cavity 111, delay aging of the components inside the first cavity 111, and improve the service life of the components inside the first cavity 111. The sealing ring 14 is simple in structure and convenient to produce.

Specifically, the seal ring 14 is an annular seal with a notch. The sealing ring 14 may be made of rubber, and the cross-sectional shape of the sealing ring 14 may be matched with the components to be acted upon, and may be irregular ring-shaped. The sealing ring 14 can be placed on the outer wall of the corresponding component, and the gap is pressed to enable the sealing ring 14 to have elasticity, so that the sealing ring is tightly abutted to the corresponding component, and the sealing effect can be achieved.

Referring to fig. 1, 2 and 5, in some embodiments, the protection member 10 is provided with a slot 15, and the slot 15 penetrates through the sealing ring 14 and extends into the first wall 122.

In this way, the slot 15 extends through the sealing ring 14 and is connected to the first wall 122, which improves the convenience of sealing the sealing ring 14. The difficulty of mounting the conductive terminals 30 in the first and second cavities 111 and 121 is reduced. The sealing ring 14 and the first wall 122 have the advantages that the ductility is expanded through the structure of the slot 15, the damage caused by repeatedly assembling the conductive terminal 30 is reduced, and the service life of the sealing ring 14 and the first wall 122 is prolonged.

In particular, the slot 15 may be located in an intermediate region of the sealing ring 14 in contact with the first wall 122, and the slot 15 may open towards the first cavity 111. The slot 15 may be formed by a straight line segment and a circular segment, and the straight line segment and the circular segment are connected to form the slot 15. Since the rubber has good elasticity, the shape of the slot 15 can be enlarged by applying an external force to the straight line segment on one or both sides of the slot 15, and thus, the conductive terminal 30 can be inserted into the second cavity 121.

Referring to fig. 1, 3 and 4, in some embodiments, the protector 10 further includes a third portion 13, the third portion 13 extends from the first wall 122 to a direction away from the second wall 123, the third portion 13 is formed with a third cavity 131, the third cavity 131 is communicated with the second cavity 121, a cross-sectional profile of the third cavity 131 includes an arc-shaped section and a straight-line section, and the straight-line section and the arc-shaped section enclose a closed profile.

Thus, the third portion 13 of the protector 10 corresponds to the curved portion 320 of the conductive terminals 30, and the protection of the conductive terminals 30 is improved. The arc segment of the third cavity 131 is the same as the curved structure 320 of the conductive terminal 30, and can be adapted to receive the portion of the curved structure 320 of the conductive terminal 30, and in appearance, the third cavity 131 can also be matched with the curved structure 320 of the conductive terminal 30, which improves the integrity of the conductive terminal 30 and the protector 10. The material of the third cavity 131 is identical to the shape of the curved formation 320 of the conductive terminal 30, which saves material from the third portion 13 of the protector 10. The third cavity 131 is connected to the second cavity 121 to better conform to the structural form of the conductive terminal 30. The closed contour of the third cavity 131 provides good protection for the portion of the curved structure 320 of the conductive terminal 30.

Specifically, the third portion 13 may be located entirely below the protector 10, the upper portion of the third portion 13 may be adjacent to the slot 112, the lower portion of the third portion 13 may be adjacent to the bottom of the second portion 12, and the third portion 13 may extend from the first wall 122 in a direction away from the second wall 123. The through form of the second cavity 121 and the third cavity 131 may be mutually perpendicular spaces. The cross-sectional profile of the third cavity 131 may be a combination of an arc segment and a straight segment, the upper portion of the cross-section may be the arc segment, the middle portion of the cross-section may be the straight segment, and the lower portion of the cross-section may be the arc segment. The arc segment is connected with the straight segment to form a closed contour of the cross section of the third cavity 131.

Referring to fig. 1, 4 and 5, in some embodiments, the protector 10 includes an extending edge 16, the extending edge 16 extends from an end of the third portion 13 away from the first wall 122 to a direction away from the first wall 122, and a hook 161 is formed at an end of each extending edge 16 away from the third portion 13.

In this way, the extending edge 16 of the third portion 13 can promote the overall extending effect of the protector 10 and has a guiding function. The wiring material may also be placed on the extended edge 16 to prevent the wire from pulling and affecting the conductive terminal 30. The hook 161 is partially connected to the extension 16 to penetrate into the member and is fixed by the hook 161 so that the protector 10 does not move back and forth from side to side, thereby improving the stability of the protector 10 as a whole.

Specifically, there may be two extending edges 16, which may extend along a straight line segment of the cross section of the third cavity 131, and the direction may be the same as the extending direction of the third portion 13. The length of the extended side 16 can be selected as appropriate. The left side of the central axis of the third cavity 131 is used as the left extending side 16, and the right side of the central axis of the third cavity 131 is used as the right extending side 16. The left extending edge 16 terminates in a hook 161 and the right extending edge 16 terminates in a hook 161. The hook 161 may be oriented away from the extending edge 16. The hook 161 may form a fixation by catching an object with the bent section. When the electric wire connected to the conductive terminal 30 extends along the extending edge 16, the electric wire can be bound to the extending edge 16 and the hook 161 by a common wire, so as to be fixed.

The protector 10 is the protector 10 in any of the above embodiments. The conductive terminal 30 is at least partially received in the first cavity 111 and the second cavity 121. The conductive terminal 30 is fixed to the mounting plate 40 by the fastener 20, and the first portion 11 covers an end of the fastener 20.

Thus, the protector 10 can be stably mounted on the electrical assembly 100, so that the protector 10 has good stability, and the conductive terminals 30 can improve the stability of the conductive terminals 30 relative to the protector 10 and the electrical assembly 100 through the effect of the protector 10 and the fasteners 20, thereby reducing the occurrence of adverse effects such as exposure or corrosion. The electrical component 100 can have better safety.

Specifically, the electrical assembly 100 may be selected to be a DC-DC converter. The protector 10 may be selected from rubber materials. The conductive terminal 30 can be formed by a flat structure 310 and a curved structure 320, and the structure is generally L-shaped. When the conductive terminal 30 structure includes the flat structure 310 and the curved structure 320, the flat structure 310 of the conductive terminal 30 can be on the upper portion of the conductive terminal 30, and the upper portion of the flat structure 310 can have a hole with a diameter larger than that of the fastening member 20. The curved structure 320 of the conductive terminal 30 may be formed by a sheet of metal that is crimped.

In one embodiment, the electrical assembly 100 is assembled as follows:

as shown in fig. 6, the first portion 11 of the protector 10 is first bent outward by about 90 degrees, and then the curved structure 320 of the conductive terminal 30 is inserted into the third cavity 131 of the protector 10, while the lower half portion of the flat structure 310 of the conductive terminal 30 enters the second cavity 121 of the protector 10;

Thus, the conductive terminals 30 and the protector 10 can be mounted on the mounting plate 40, and the mounting plate 40 can be mounted on the electrical assembly 100.
