Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a terminal assembly and electrical equipment. Background Art

[0002] Conductive wires are widely used in electrical equipment for power and signal transmission. When the conductive wire is too long or too short, it may cause inconvenience in the use of the conductive wire. For example, when the conductive wire is too long, it may bend and collide with the surrounding devices. When the conductive wire is too short, it may be difficult to achieve the purpose of conductive connection, and a longer conductive wire needs to be replaced. Even if it is barely pulled to connect, it may affect the conductive contact surface and the reliability of the conductive connection. In severe cases, it may even cause deformation of the circuit board connected by the conductive wire.

[0003] In particular, in photovoltaic equipment, some conductive wires need to pass through the circuit board and then be connected to the terminals on the surface of the circuit board after being turned 90° by the conductive terminals at their ends. When the conductive wires are too long due to pre-determination errors and other reasons, the conductive wires may collide with other components or vias on the circuit board. When the conductive wires are too short due to pre-determination errors and other reasons, the circuit board will be pulled along the thickness direction of the circuit board, causing deformation of the circuit board and affecting the performance of the circuit board.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or embodiment. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or embodiments in a suitable manner.

[0035] The terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0036] In the accompanying drawings, the Z axis represents the vertical direction, that is, the up and down position, and the positive direction of the Z axis (that is, the direction of the arrow of the Z axis) represents the up, and the negative direction of the Z axis represents the down; in the accompanying drawings, the Y axis represents the horizontal direction and is designated as the left and right position, and the positive direction of the Y axis (that is, the direction of the arrow of the Y axis) represents the right side, and the negative direction of the Y axis represents the left side; in the accompanying drawings, the X axis represents the front and back position, and the positive direction of the X axis (that is, the direction of the arrow of the X axis) represents the front side, and the negative direction of the X axis represents the back side; it should be noted that the aforementioned Z axis, Y axis and X axis are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] like Figure 1 and Figure 2 As shown, the utility model provides a terminal assembly, including a guide sliding reset unit 1 and a sliding seat 2, the guide sliding reset unit 1 includes a guide sliding seat 11 for conductively connecting with a circuit board 3, the guide sliding seat 11 includes a plurality of guide slide plates 111, the sliding seat 2 is respectively and slidably conductively connected with the plurality of guide slide plates 111 along a set direction, the guide sliding reset unit 1 is also used to reset the sliding seat 2 toward a set end along a set direction, the sliding seat 2 is used to be connected with a conductive wire 4, when one end of the conductive wire 4 connected with the sliding seat 2 moves along the set direction toward the set end, the conductive wire 4 is gradually tightened.

[0038] It should be understood that the setting of the setting direction is mainly determined according to the main extension direction of the conductive wire 4. The selection of the setting direction and the setting end needs to make the conductive wire 4 gradually tightened when the end of the conductive wire 4 used to be connected to the sliding seat 2 moves along the setting direction toward the setting end, and the conductive wire 4 gradually becomes loose when the end of the conductive wire 4 used to be connected to the sliding seat 2 moves along the setting direction toward the end away from the setting end. Therefore, when the end of the conductive wire 4 connected to the guide slide seat 11 is located within the sliding stroke of the guide slide seat 11, the conductive wire 4 can be gradually tightened to a certain extent when the sliding seat 2 slides along the setting direction toward the setting end, and accordingly, when the sliding seat 2 slides along the setting direction toward the end away from the setting end, the conductive wire 4 can be gradually loosened.

[0039] In this specification, the content of the utility model is mainly described by taking the setting direction being consistent with the main extension direction of the conductive wire 4, specifically consistent with the Z-axis direction in the figure, and the setting end being an end located in the positive direction of the Z-axis as an example, but it should be understood that the setting direction only needs to have a projection in the main extension direction of the conductive wire 4, for example, the setting direction and the main extension direction of the conductive wire 4 have an angle, for example, the angle is 0-60°, 0-30°, 0-10°. Generally speaking, the smaller the angle, the stronger the adaptability of the terminal assembly to the length error of the conductive wire 4.

[0040] The guide slide reset unit can provide a reset force for the sliding seat 2 to reset along the set end. The specific implementation method is not limited. For example, it can provide the reset force through an elastic reset member, or it can be implemented by means of a specific structure connecting the sliding seat 2 and the guide slide plate 111, which will be explained exemplarily below.

[0041] It should be understood that the sliding seat 2 moves along the set direction to tighten the conductive wire 4, and the force used to pull the conductive wire 4 should not cause adverse effects such as breaking or cracking on the structure of the conductive wire 4 itself and the connection structures at both ends.

[0042] In this way, the guide slide reset unit 1 includes a guide slide seat 11 for conductively connecting with the circuit board 3, the sliding seat 2 is conductively connected to the guide slide plate 111 of the guide slide seat 11 in a slidable manner along a set direction, the sliding seat 2 is connected to the conductive wire 4, and the guide slide reset unit 1 is also used to reset the sliding seat 2 to a set end along the set direction. When the end of the conductive wire 4 connected to the sliding seat 2 moves along the set direction toward the set end, the conductive wire 4 is gradually tightened. For example, when the end of the conductive wire 4 connected to the sliding seat 2 moves upward along the up-down direction, the conductive wire 4 is gradually tightened. When the end of the conductive wire 4 connected to the guide slide seat 11 is located at the sliding end of the guide slide seat 11, the conductive wire 4 is gradually tightened. In the moving stroke, when the length of the conductive wire 4 is long, the sliding seat 2 can be connected to the conductive wire 4 at a position closer to the upper end to avoid the conductive wire 4 being too loose and having the risk of colliding with other parts. When the length of the conductive wire 4 is short, the sliding seat 2 can be connected to the conductive wire 4 at a position closer to the lower end to avoid the conductive wire 4 being too short and pulling the circuit board 3 to cause the circuit board 3 to deform. Under the reset force of the guide slide reset unit 1, the conductive wire 4 can be kept in a suitable tension state by sliding the sliding seat 2 along the up and down directions, thereby meeting the connection requirements of the conductive wire 4 on the basis of reducing the length accuracy requirements of the conductive wire 4. In addition, the guide slide seat 11 includes a plurality of guide slide plates 111. On the one hand, the sliding seat 2 can form a plurality of conductive paths from the conductive wire 4 to the circuit board 3 through the plurality of guide slide plates 111, ensuring the reliability of the conductive connection from the conductive wire 4 to the circuit board 3. On the other hand, the sliding seat 2 is slidably connected to the guide slide seat 11 at the plurality of guide slide plates 111, and the sliding seat 2 can obtain good sliding stability along the set direction. In general, the utility model can reduce the length accuracy requirement of the conductive wire 4 when performing conductive connection and ensure the conductive reliability of the conductive connection.

[0043] Optionally, the setting direction is extended along the thickness direction of the circuit board 3 .

[0044] In this embodiment, the circuit board 3 is parallel to the XY plane, and the conductive reset unit is connected to the circuit board 3 on the upper side of the circuit board 3. At this time, the sliding seat 2 can be used to connect with the conductive wire 4 extending mainly along the Z-axis direction, and the set end can be the upper end or the lower end. The space occupied by the terminal assembly on the plane where the circuit board 3 is located can be reduced to a certain extent.

[0045] Optionally, the set end is an end away from the circuit board 3 in the set direction.

[0046] In this embodiment, the set end is the upper end. At this time, the conductive wire 4 mainly extends from bottom to top and passes through the circuit board 3 to connect with the sliding seat 2. This specification will be mainly described as an example in the following.

[0047] like Figure 1 and Figure 2As shown, illustratively, a via hole 31 is provided on the circuit board 3, and the conductive wire 4 passes through the via hole 31 from bottom to top.

[0048] In this way, when the conductive wire 4 is long, the guide sliding reset unit 1 causes the sliding seat 2 to move upward, thereby tightening the conductive wire 4. When the conductive wire 4 is short and there is a risk that it cannot be connected to the sliding seat 2, the reset force that causes the sliding seat 2 to reset upward is overcome, causing the sliding seat 2 to move downward, so that the conductive wire 4 can be smoothly connected to the sliding seat 2, compensating for the risk of not being able to connect when the conductive wire 4 is short.

[0049] like Figure 1 As shown, the conductive wire 4 generally includes a conductive wire 41 and a conductive terminal 42. The conductive wire 41 is arranged in the through hole 31 along the up-down direction. The upper end of the conductive wire 41 is connected to the conductive terminal 42. The conductive terminal 42 extends in the XY plane and is connected to the sliding seat 2. For example, a connecting plate for connecting with the conductive terminal 42 is set on the sliding seat 2. At this time, it corresponds to the case where the conductive wire 4 changes direction by 90° through the conductive terminal 42. It should be understood that the conductive wire 4 does not need to change direction. At this time, the connecting hole 23 is set on the side wall of the sliding seat 2, which will not be described in detail here.

[0050] like Figure 1 and Figure 3 As shown, optionally, the plurality of guide slides 111 include at least one pair of guide slides 111 , and the two guide slides 111 of the same pair are arranged opposite to each other along a first direction, and the first direction is perpendicular to the set direction.

[0051] In this embodiment, the first direction is the left-right direction, that is, the Y-axis direction in the figure. However, it should be understood that the guide slides 111 can be provided in multiple pairs, and the distribution directions of the two guide slides 111 in different pairs are different, for example, a pair of guide slides 111 is provided in the left-right direction, and another pair of guide slides 111 is provided in the front-rear direction.

[0052] At this time, a relatively large interval can be obtained between the two guide slides 111, which is convenient for arranging the position of the sliding seat 2 and can ensure the stability of the sliding seat 2 in the up and down directions to a certain extent.

[0053] like Figures 6 to 9 As shown, optionally, the sliding seat 2 is located between two oppositely disposed guide slides 111 and abuts against the inner wall surface 111 a of the guide slide 111 located in the first direction.

[0054] In this way, the movement of the sliding seat 2 relative to the guide slide plate 111 in the first direction can be limited by the abutment between the sliding seat 2 and the inner wall surface 111a. The structure is simple and practical. When the conductive wire 4 is connected to the sliding seat 2 through, for example, a conductive terminal 42 extending along the first direction, the guide slide plate 111 can also form protection for the conductive terminal 42 in the first direction to a certain extent. The structure is simple and practical.

[0055] like Figures 1 to 3 As shown, different from the situation where the sliding seat 2 abuts against the inner wall surface 111a of the guide slide plate 111, optionally, the sliding seat 2 is provided with clamping plates 22 at both ends along the first direction, and the two clamping plates 22 are respectively located at the outer ends of the guide slide plate 111 along the first direction, and the clamping plates 22 abut against the corresponding outer wall surface 111b of the guide slide plate 111.

[0056] Exemplarily, the sliding seat 2 includes a seat body 21 and clamping plates 22 connected to both ends of the seat body 21 along the first direction, and the seat body 21 is provided with connecting holes 23 for connecting with the conductive terminals 42. The sliding seat 2 may be in a U-shaped structure as a whole.

[0057] At this time, the position of the seat body 21 in the up and down direction can be higher than the top of the guide slide 111, and it is connected to the two guide slides 111 respectively through the clamping plates 22 at both ends in the left and right directions, which can also limit the movement of the sliding seat 2 relative to the guide slide 111 in the first direction.

[0058] Optionally, the guide slide seat 11 further includes an intermediate plate 112, and the ends of the two guide slides 111 away from the setting end along the setting direction are connected through the intermediate plate 112, and the ends of the two guide slides 111 close to the setting end along the setting direction are spaced apart.

[0059] Figure 1 In the embodiment, the lower ends of the guide slide plates 111 are connected via the middle plate 112, and the upper ends are spaced apart. At this time, the guide slide seat 11 as a whole is in a C-shaped structure with its opening facing upward.

[0060] like Figure 1 and Figure 3 As shown, optionally, the guide slide plate 111 is arranged at an angle; when the sliding seat 2 abuts against the outer wall surface 111b through the clamping plate 22, when the sliding seat 2 abuts against the outer wall surface 111b through the clamping plate 22, the distance between the relative inner wall surfaces 111a gradually decreases along the set direction close to the set end.

[0061] The inclination angle of the guide slide 111 is set according to actual needs. For example, the angle between the guide slide 111 and the XZ plane is 0-10°, 2-8°, or 3°.

[0062] When the sliding seat 2 moves from top to bottom, the contact force between the clamping plate 22 and the outer wall surface 111b of the guide slide 111 continues to increase, and the clamping plate 22 and the guide slide 111 are deformed. To a certain extent, energy is stored through the deformation of the clamping plate 22 and the guide slide 111, providing a restoring force for the sliding seat 2 to slide upward.

[0063] Optionally, the guide plate 111 is tilted; when the sliding seat 2 abuts against the inner wall surface 111a, the distance between the opposite inner wall surfaces 111a gradually increases along the direction close to the set end in the set direction. This can also achieve a similar effect, which is not shown in the diagram and will not be described in detail here.

[0064] Optionally, the guide slide resetting unit 1 further comprises an elastic resetting member, which is used to provide a resetting force for resetting the slide seat 2 to a set end along a set direction.

[0065] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, optionally, the elastic return member includes a first elastic return member 12, which is telescopically connected to the two guide slides 111 along a first direction; when the sliding seat 2 abuts against the outer wall surface 111b through the clamping plate 22, the first elastic return member 12 is a compression spring.

[0066] At this time, the compression spring can provide a force for the upper end of the guide slide plate 111 to expand outward in the left-right direction, which will eventually be converted into a reset force to move the sliding seat 2 upward. The reset performance of the guide slide reset unit 1 to reset the sliding seat 2 can be improved. The setting position and number of the compression spring can be determined according to actual needs and are not a limitation.

[0067] like Fig. 9 As shown, in another embodiment, when the guide slide seat 11 abuts against the inner wall surface 111a, the first elastic reset member 12 is a tension spring. At this time, the tension spring can be connected to the upper end of the guide slide plate 111 to reduce the possibility of the tension spring colliding with the slide seat 2.

[0068] like Figures 6 to 8 As shown, different from the manner in which the upper elastic reset member includes the first elastic reset member 12, optionally, the elastic reset member includes a second elastic reset member 13, and the second elastic reset member 13 is telescopically connected to the guide slide 111 and the sliding seat 2 along a set direction.

[0069] At this time, the second elastic return member 13 acts more directly between the guide sliding seat 11 and the sliding seat 2. When the sliding seat 2 moves toward the set end, the potential energy of the second elastic return member 13 decreases. When the sliding seat 2 moves toward the end away from the set end, the potential energy of the second elastic return member 13 increases. The second elastic return member 13 can be set to, for example, a tension spring or a compression spring, which is determined according to actual needs.

[0070] It should be understood that, in this case, there is no limitation on whether the guide slide plates 111 are inclined or not, and whether they are two opposite ones.

[0071] In the above embodiment, optionally, a guide groove 113 and a sliding block 24 are respectively provided on the guide slide plate 111 and the sliding seat 2, the guide groove 113 extends along a set direction, and the sliding block 24 is inserted into the guide groove 113 and slidably connected to the guide groove 113.

[0072] In this embodiment, the cross section of the sliding block 24 (the cross section is a cross section perpendicular to the setting direction) can be circular or rectangular, which is not a limitation. Figures 1 to 3 The first embodiment shown and Figures 4 to 5 In the second embodiment shown, the cross section is circular. Figures 6 to 8 In the third embodiment shown, the cross section is rectangular.

[0073] like Figure 6 As shown, it shows that the second elastic return member 13 is a compression spring and is located in the guide groove 113, wherein the compression spring located on the left side is not shown. At this time, the sliding seat 2 and the guide groove 113 can both be provided with a positioning column for positioning the compression spring.

[0074] In this case, the space occupied by the second elastic return member 13 between the two guide slides 111 can be reduced, the spatial structure is compact, and the reliability is high.

[0075] like Figure 1 As shown, optionally, the guide slide seat 11 is connected to the circuit board 3 in a fixed relative position, for example, by welding. In this case, the connection structure between the two is simple and the conductive stability is high.

[0076] like Figure 4 and Figure 5 As shown, different from the above-mentioned solution of welding connection between the guide slide seat 11 and the circuit board 3, optionally, the guide slide reset unit 1 also includes a connecting seat 14, and the connecting seat 14 is fixedly connected to the circuit board 3 in a relative position, for example, by welding, and the guide slide seat 11 and the connecting seat 14 are conductively connected so as to be relatively rotatable, and the guide slide seat 11 extends along a set direction relative to the axis of rotation of the connecting seat 14.

[0077] At this time, the guide slide seat 11 and the sliding seat 2 thereon can rotate relative to the connecting seat 14 and the circuit board 3 as needed, and the rotation angle of the guide slide seat 11 relative to the connecting seat 14 can be flexibly adjusted according to the need to connect the conductive wire 4.

[0078] Optionally, the guide slide reset unit 1 also includes a baffle 16 and a first elastic member 15, the connecting seat 14 includes a column 141 and a stop portion 142, a through hole 114 is provided on the guide slide seat 11, the column 141 includes a first end and a second end relatively arranged, the second end of the column 141 is passed through the through hole 114, the baffle 16 and the circuit board 3 and is connected to the circuit board 3, for example, by welding, the stop portion 142 is located at the first end of the column 141, the first elastic member 15 is located between the stop portion 142 and the edge of the through hole 114, and respectively abuts against the stop portion 142 and the edge of the through hole 114.

[0079] by Figure 4 Taking the scheme shown as an example, the first elastic member 15 is a compression spring, which is sleeved on the column 141, with the upper end abutting against the stopper 142 and the lower end abutting against the edge of the through hole 114, thereby limiting the guide slide seat 11 from upwardly separating from the connection seat 14, and the blocking piece 16 can directly press the guide slide seat 11 on the circuit board 3, and can also prevent the solder from flowing to the through hole 114 when the column 141 is welded to the circuit board 3, causing the column 141 and the guide slide seat 11 to be welded.
