Detailed Description

To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is to be understood that the described embodiment is only a component embodiment of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

As shown in fig. 1, fig. 2 and fig. 3, a terminal box 100 according to an embodiment of the present invention includes a housing 110, a terminal 120 and a wire clip 130.

The housing 110 has a wire inlet 111 penetrating through the inside and the outside, that is, the housing 110 has an inner cavity, the wire connecting terminal 120 and the wire pressing elastic piece 130 are located in the inner cavity of the housing 110, and a wire clamping space is formed between the wire connecting terminal 120 and the wire pressing elastic piece 130. The wire pressing elastic piece 130 is disposed near the wire inlet 111 opposite to the wire terminals 120.

As shown in fig. 4, the wire connecting terminal 120 has the wire abutting portion 121 and the mounting portion 122, which are oppositely disposed, and the connecting plate 123. The mounting portion 122 is arranged facing the housing 110, i.e. the terminal 120 is fixed in the housing 110 by means of the mounting portion 122. The connecting plate 123 connects the wire abutting portion 121 and the mounting portion 122, the connecting plate 123 is provided with an adjacent insertion space 1231 and a hooking support portion 1232, the insertion space 1231 penetrates through the connecting plate 123, and the hooking support portion 1232 is far away from the wire abutting portion 121 and is close to the mounting portion 122.

As shown in fig. 5, the wire pressing elastic piece 130 has a first free portion 131 and a first fixing portion 132, a wire clamping space is formed between the first free portion 131 and the wire abutting portion 121, the first free portion 131 is close to the wire clamping space relative to the first fixing portion 132, and when the first free portion 131 of the wire pressing elastic piece 130 receives an external force close to the first fixing portion 132, the first free portion 131 is also far away from the wire clamping space. The fixing base may include a hanging region 1321, and the hanging region 1321 penetrates the inserting space 1231 from one side of the wire inlet 111 and is hooked on the hanging support part 1232, that is, the hanging region 1321 is supported by the hanging support part 1232.

Of course, the first free portion 131 and the first fixed portion 132 of the wire pressing strip 130 are relative. Because the terminal 120 has a clamping space and a hooking support 1232, the wire clip 130 has a hooking area 1321 matching with the clamping space and the hooking support 1232, so that the first fixing portion 132 of the wire clip 130 can be at least partially supported by the terminal 120, and further, the problem of stress concentration of the housing 110 when the wire clip 130 is stressed due to complete support by the housing 110 is avoided.

The inserting space 1231 may be a square on the connecting plate 123, that is, it is disposed through the middle of the connecting plate 123, or may not be a square but is communicated with the edge of the connecting plate 123.

A wire clamping space is formed between the first free portion 131 and the wire abutting portion 121, and thus the first free portion 131 is close to or away from the wire abutting portion 121 under the action of external force, so that the size of the wire clamping space is increased or reduced, and a wire can penetrate into the wire clamping space or be clamped in the wire clamping space.

In order to facilitate the wire to penetrate along a straight line and to be clamped in the wire clamping space, the axis of the wire inlet 111 and the wire clamping space are on the same straight line. Obviously, the number of the wire inlets 111 may be equal to the number of the wire clamping spaces, and equal to the number of the wire pressing spring pieces 130 and the wire connecting terminals 120.

In order to further reduce the problem of concentrated stress on the housing 110 when the wire clip 130 is stressed, in the embodiment of the present invention, the first free portion 131 may partially penetrate into the insertion space 1231 and abut against the wire abutting portion 121 (see fig. 7). The wire abutting portion 121 is located on one side of the connecting plate 123 away from the wire inlet 111, the first free portion 131 penetrates the inserting space 1231 from one side of the wire inlet 111 and then abuts against the wire abutting portion 121 in a normal state, and a wire clamping space is formed between the wire abutting portion 121 and the first free portion 131. First free portion 131 just can butt wire butt portion 121 under the normality (when there is not exogenic action to warp), and the wire joint space is less under the normality that is to say, and the wire can be by the centre gripping wherein, and under first free portion 131 receives exogenic action, keeps away from wire butt portion 121 and then increase wire joint space just size to the wire connects to connect to the wire joint space in from inlet 111.

Therefore, in the embodiment of the present invention, the first fixing portion 132 and the first free portion 131 of the wire pressing elastic piece 130 on the terminal box 100 both have a portion penetrating into the inserting space 1231 and abutting against the wiring terminal 120, so that when the wire pressing elastic piece 130 is stressed, these pressures are at least partially transmitted to the wiring terminal 120 and transmitted to the casing 110 by the wiring terminal 120, thereby avoiding the problem that the pressure applied by the wire pressing elastic piece 130 to the casing 110 is too concentrated.

In an embodiment of the present invention, the wire abutting portion 121 may include a wire abutting surface, which is disposed toward the mounting portion 122 and may be a serrated surface 1211 (see fig. 6) to improve the static friction force of the wire clamped in the wire clamping space. Wherein, each zigzag extending direction of the zigzag surface 1211 can be perpendicular to the axis of the wire inlet 111. Of course, the wire abutting portion 121 may further include a wire abutting back surface, the wire abutting back surface and the wire abutting back surface are opposite to each other, and the wire abutting back surface may be attached to the inner wall of the housing 110, so as to improve the stability of the connection terminal 120 inside the housing 110.

The attachment region 1321 may be formed by a cuff in the first fixed portion 132 that is remote from the first free portion 131 (see fig. 5). The cross-section of the hitch region 1321 may be curved to allow for overlap of the hitch mount 1232. The hanging region 1321 may include a hanging surface facing the hanging support portion 1232 and away from the first free portion 131, and obviously, the hanging surface is a pressed surface of the wire pressing elastic piece 130, and when the first free portion 131 of the wire pressing elastic piece 130 is acted by an external force, the hanging surface bears a pressure and abuts against the hanging support portion 1232.

The mounting portion 122 includes a mounting surface 1221, and the mounting surface 1221 is configured to be attached to an inner wall of the housing 110 and faces away from the wire abutting portion 121. The housing 110 is provided with a pressing opening 112 and a pressing piece 113, the pressing opening 112 penetrates through the housing 110, the pressing piece 113 is movably arranged on the pressing opening 112 along the axial direction of the pressing opening 112, the pressing opening 112 and the pressing piece 113 are arranged opposite to the mounting surface 1221, the first free portion 131 of the wire pressing elastic piece 130 is arranged close to the pressing opening 112, and the first free portion 131 is far away from the pressing opening 112, namely the first fixing portion 132 is arranged close to the mounting portion 122. The pressing member 113 passes through the pressing opening 112 and abuts against the first free portion 131, and drives the first free portion 131 to be disposed close to the first fixing portion 132, i.e., away from the wire abutting portion 121 under the external force applied from the outside of the housing 110.

The embodiment of the present invention provides an axial direction of the wire inlet 111 and an axial direction of the pressing opening 112 can be perpendicular to each other, that is, after the external wire is inserted into the wire clamping space from the wire inlet 111, the pressing member 113 can apply deformation pressure to the first free portion 131 along the direction of inserting the wire perpendicular to the wire. The axial direction of the inlet 111 is parallel to the surface of the mounting surface 1221, and the axial direction of the pressing opening 112 is perpendicular to the mounting surface 1221. Of course, in some embodiments, the axis of the wire inlet 111 and the axis of the pressing opening 112 may not be perpendicular to each other, so as to achieve the function of the wire pressing elastic piece 130.

As shown in fig. 2 and 5, the wire clip 130 further includes an arc bending region 133, and the first fixing portion 132 further includes a first transition region 1322, where the first transition region 1322 connects the arc bending region and the hooking region 1321. The first free portion 131 includes a narrowed region 1311 and a second transition region 1312. The second transition region 1312 is connected between the arc bending region 133 and the narrow region 1311 and abuts against the pressing piece 113, and the narrow region 1311 penetrates into the insertion space 1231 and abuts against the wire abutting portion 121. First transition area 1322 and second transition area 1312 are disposed opposite to each other, and hitching area 1321 is formed by flanging from first transition area 1322 in a direction away from second transition area 1312. In the wire pressing elastic piece 130, the extension surfaces of the first transition region 1322, the second transition region 1312 and the narrow region 1311 are all inclined, and the first transition region 1322, the second transition region 1312 and the narrow region 1311 are gradually far away from the wall surface of the wire inlet 111 from the mounting portion 122 to the pressing opening 112. Therefore, the narrow section 1311 and the second transition section 1312 are inclined so as not to prevent the wire from penetrating into the wire clamping space (or to provide a certain guiding function), and since the extension surfaces of the narrow section 1311 and the second transition section 1312 do not extend in the axial direction of the wire inlet 111, the narrow section 1311 and the second transition section 1312 can exert a large elastic force on the wire abutting portion 121.

It should be understood that the wire clip 130 is made of a metal elastic material or is integrally disposed, and the second transition region 1312 may have elasticity and be capable of being deformed appropriately. The circular arc bending region 133 and the first transition region 1322 may abut against the inner wall of the housing 110, so that the wire clip 130 may be directly supported by the housing 110 in addition to the terminal 120 in the housing 110, thereby providing high stability in the housing 110.

In order to facilitate the hooking of the hooking region 1321 to the hooking support 1232 after the hooking region 1321 penetrates into the insertion space 1231, so that the hooking support 1232 can support the hooking region 1321, and to improve the reliability of the hooking region 1321 to the hooking support 1232, the connecting plate 123 is also obliquely arranged in the housing 110 with respect to the mounting surface 1221, and the connecting plate 123 gradually approaches the wall surface of the wire inlet 111 from the mounting portion 122 to the pressing port 112. In other words, the extension surfaces of the connecting plate 123 and the narrow regions 1311, the first transition regions 1322, and the second transition regions 1312 of the wire clip 130 are substantially perpendicular to each other. In addition, the connection plate 123 is disposed obliquely in such a manner that the wire abutting portion 121 is close to the wall surface of the wire inlet 111, thereby reducing the size of the terminal box 100.

It should be noted that the connection plate 123 and the wire pressing elastic piece 130 are obliquely arranged relative to the mounting surface 1221 of the wire connecting terminal 120, and the mounting surface 1221 is considered to be horizontally arranged in the housing 110 in no particular case.

In the embodiment of the present invention, as shown in fig. 4, the connecting terminal 120 may further include a positioning portion 124, the positioning portion 124 extends from the wire abutting portion 121 toward the wall of the wire inlet 111, and the positioning portion 124 may abut against the inner wall of the casing 110, thereby further improving the stability of the connecting terminal 120 in the casing 110. Of course, the positioning portion 124 may also be suspended without abutting against the inner wall of the housing 110.

At least two terminals 120 arranged in parallel may be included in the terminal block 100, and a connection direction of the at least two terminals 120 may be defined as a width direction. The width dimension of the positioning part 124 may be equal to the width dimension of the insertion space 1231. Alternatively, the outer dimension of the positioning portion 124 may be equal to the outer dimension of the insertion space 1231, specifically, the length dimension, the width dimension, and the rear dimension of the positioning portion and the insertion space are the same. Obviously, in this case, the positioning portion 124 may be formed by folding a metal portion on the socket space.

Also, the width dimension of the connection plate 123 and the width dimension of the wire abutting portion 121 may be equal.

In order to enable the pressing member 113 provided on the pressing port 112 to drive the first free portion 131 to move when moving in the axial direction, a line on which the pressing member 113 can move at least partially overlaps the first free portion 131 in a direction perpendicular to the mounting surface 1221, in other words, an orthographic projection of the first free portion 131 on the mounting surface 1221 overlaps an orthographic projection of the pressing member 113 on the mounting surface 1221 in a direction perpendicular to the mounting surface 1221. However, due to the arrangement of the positioning portion 124 on the wire connecting terminal 120, the positioning portion 124 may be located between the pressing member 113 and the first free portion 131, and obviously, the positioning portion 124 should avoid the force applied by the pressing member 113 to the first free portion 131.

In the embodiment of the present invention, the pressing member 113 has a pressing foot 1131 (see fig. 3), and the pressing foot 1131 extends toward the first free portion 131 and avoids the positioning portion 124. Specifically, a relief hole may be formed in the positioning portion 124 so that the pressing leg 1131 can abut against the first free portion 131 after passing through the first free portion, or as in the present application, the width of the positioning portion 124 is small, and the position where the first free portion 131 abuts against the pressing leg 1131 has a large width, so that the pressing leg 1131 can pass through both sides of the positioning portion 124 and abut against the first free portion 131.

The first free portion 131 may include a narrow region 1311 and a second transition region 1312, and since the narrow region 1311 penetrates into the insertion space 1231, the second transition region 1312 is located outside the insertion space 1231 and is used for abutting against the pressing member 113. The second transition region 1312 is close to the wire inlet 111 and far away from the wire abutting portion 121, the narrow region 1311 can penetrate into the insertion space 1231 and then abut against the wire abutting portion 121, that is, the width of the narrow region 1311 can be smaller than or equal to the width of the insertion space 1231, the width of the second transition region 1312 is larger than the width of the narrow region 1311, so as to limit the penetration depth of the narrow region 1311, the second transition region 1312 is located outside the insertion space 1231 and abuts against the pressing piece 113, and the first free portion 131 can be driven to deform under the action of the pressing piece 113.

In order to enable pressing foot 1131 to abut second transition area 1312 of first free portion 131 without contacting positioning portion 124 located between pressing piece 113 and first free portion 131, the width dimension of second transition area 1312 area is greater than the width dimension of positioning portion 124, pressing foot 1131 may avoid positioning portion 124 and abut second transition area 1312, i.e. pressing foot 1131 maintains a spacing from positioning portion 124.

Although the second transition area 1312 and the first free portion 131 are disposed obliquely with respect to the mounting surface 1221 in the embodiment of the present invention, in order to improve the pressing effect of the pressing member 113 on the second transition area 1312, the end surface of the pressing foot 1131 facing the second transition area 1312 may be a horizontal surface, and the portion of the second transition area 1312 abutting against the pressing foot 1131 may also be a horizontal surface (parallel to the mounting surface 1221).

In the embodiment of the present invention, in the direction perpendicular to the width direction, it can be seen that the wire pressing elastic piece 130 is substantially U-shaped, the narrow region 1311 and the hanging region 1321 are respectively located at the two ends of the U-shaped, that is, the second transition region 1312 and the first transition region 1322 are substantially parallel to each other. Moreover, in order to enable the hanging area 1321 to penetrate into the plugging space 1231, the width dimension of the hanging area 1321 is smaller than or equal to the width dimension of the plugging space 1231, and the width dimension of the second transition area 1312 is larger than the width dimension of the plugging space 1231.

As shown in fig. 4, in the embodiment of the present invention, the connection terminal 120 may further include a coupling portion 125 and a strain portion 126, the strain portion 126 connects the mounting portion 122 and the coupling portion 125, and the strain portion 126 extends from the mounting portion 122 toward a direction away from the mounting surface 1221. The coupling portion 125 is used for electrical connection with the mating electrical component of the terminal box 100, and the strain portion 126 is deformable and used for providing the coupling portion 125 with the capability of moving after being stressed, so as to improve the reliability of electrical connection between the coupling portion 125 and other electrical components. Further, the coupling portion 125 may be distant from or close to the mounting portion 122 with respect to the wire abutting portion 121 in a direction perpendicular to the mounting surface 1221. Of course, the coupling portion 125 is far away from the mounting portion 122 relative to the wire abutting portion 121 so that the strain portion 126 has a sufficient length dimension, which further improves the deformability of the strain portion 126 and the reliability of the electrical connection between the coupling portion 125 and other components.

In the embodiment of the present invention, as shown in fig. 4, the connection terminal 120 may further include an elastic reinforcement portion 127, and the elastic reinforcement portion 127 is connected between the strain portion 126 and the installation portion 122 for improving the strain capacity of the strain portion 126 and reducing the probability of elastic failure after the strain portion 126 deforms. The elastic reinforcement portion 127 may be bent in a V shape and is disposed closer to the mounting portion 122 than the coupling portion 125.

When the first electrical connection portion 210 is the terminal box 100 of embodiment 1 of the present invention, in order to realize the detachable connection of the bottom portion 241 and the terminal box 100, the second detachable connection portion 242 should be provided on the bottom portion 241, and the second detachable connection portion 242 is used for detachable connection with the first detachable connection portion 117 of the terminal box 100.

In order to detachably connect the first main body 240 and the terminal box 100, the structure of the second detachable connecting portion 242 of the present application and the connection manner with the first detachable connecting portion 117 in embodiment 1 are described below.

The second detachable connecting portion 242 may include the bottom end portion 241 and a jaw 2421, the jaw 2421 is arranged along a circumferential direction of a rotating shaft 10 (the same as the rotating shaft 10 in embodiment 1), the jaw 2421 is disposed close to the connecting base 300 relative to the bottom end portion 241, a clamping gap 2422 is formed between the jaw 2421 and the top end portion 341, and the clamping gap 2422 is adapted to clamp a fastening area 1174 of the junction box 100.

In order to improve the compactness of the structure, the notch 1172 may also be an open ring opening in the embodiment of the present invention, at this time, since the notch 1172 needs to be matched with the jaw 2421, the limiting baffle 2423 may be naturally disposed between two adjacent jaws 2421 for abutting against the outer edge of the extension 1171 of the housing in the terminal box 100, and thus the structure of the first detachable connecting portion 117 and the second detachable connecting portion 242 may be more compact. As a variation, the notch 1172 on the bottom end plate may also be a closed-loop notch 1172 when viewed from the axial direction, i.e. not penetrating to the outer edge of the bottom end plate, at this time, since the notch 1172 and the jaw 2421 need to be aligned and matched, the limit stop 2423 naturally needs to be spaced from the jaw 2421 in order to abut against the outer edge of the bottom end plate, and the limit stop 2423 is disposed at the periphery of the jaw 2421.
