Description

Technical Field

[0001] This disclosure relates to an anti-electric shock cover to prevent electric shock caused by contact with terminal parts, and a connector with an anti-electric shock cover on the terminal parts. Background Technology

[0002] Traditionally, in high-voltage connectors used in vehicles such as hybrid electric vehicles and electric vehicles, anti-electric shock structures are required to prevent electric shock caused by contact between the fingers, tools, etc., of personnel handling the connectors and terminal parts. For example, Patent Document 1 shows a protective cover that covers the periphery of the top portion of the terminal body, which is formed into a flat plate.

[0004] Patent documents

[0005] Patent Document 1: Japanese Patent Application Publication No. 2019-185932 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] However, when the protective cover is installed relative to the flat terminal body in a manner that covers the periphery of both sides of the terminal body excluding the thickness direction, the contact area between the protective cover and the terminal body is small, and the retaining force for holding the protective cover in the installed state attached to the terminal body becomes weak. As a result, it is difficult to install the protective cover onto the terminal body, and the protective cover installed on the terminal body is prone to detaching from the terminal body.

[0008] Furthermore, as shown in Patent Document 1, when the connector has a pair of terminal parts, protective covers are installed on the terminal bodies of each terminal part. However, this increases the number of protective covers, making the installation of the protective covers onto the terminal bodies more complicated. Moreover, since the opposing surfaces of the pair of terminal bodies are not covered by the protective covers, ribs protruding from the connector housing towards the pair of terminal bodies need to be provided independently of the anti-electric shock cover to prevent fingers or tools from entering between the pair of terminal bodies.

[0009] Therefore, a novel structure of anti-electric shock cover and a connector with anti-electric shock cover using the following are disclosed: it is easy to install on a pair of terminal body parts, can obtain a relatively large holding force, and can also prevent contact with the opposing surfaces of the pair of terminal body parts.

[0010] Solution for solving the problem

[0011] The electric shock protection cover disclosed herein includes: a pair of peripheral covering portions installed on a pair of terminal body portions formed in a flat plate shape and arranged in the thickness direction, covering the periphery of the top portion of the pair of terminal body portions; and an inner anti-intrusion portion disposed between the pair of peripheral covering portions, connecting the pair of peripheral covering portions to each other, wherein, when the electric shock protection cover is installed on the pair of terminal body portions, at least one surface of the terminal body portion in the thickness direction is exposed.

[0012] Invention Effects

[0013] According to this disclosure, it is easy to install on a pair of terminal body parts, can obtain a relatively large holding force, and can also prevent contact with the opposing surfaces of the pair of terminal body parts. Attached Figure Description

[0027] <Description of embodiments of this disclosure>

[0028] First, embodiments of this disclosure will be described and illustrated.

[0029] The electric shock protection cover disclosed herein

[0030] (1) Includes: a pair of peripheral covering portions installed on a pair of terminal body portions formed in a flat plate shape and arranged in the thickness direction, covering the periphery of the top portion of the pair of terminal body portions; and an inner anti-intrusion portion disposed between the pair of peripheral covering portions, connecting the pair of peripheral covering portions to each other, wherein, with the anti-electric shock cover installed on the pair of terminal body portions, at least one surface in the thickness direction of the terminal body portion is exposed.

[0031] According to the electric shock protection cover disclosed herein, since a pair of peripheral covering portions are connected to each other by an inner anti-intrusion portion, they can be installed simultaneously on a pair of terminal body portions arranged together. Furthermore, because the electric shock protection cover is installed on a pair of terminal body portions together, the overlap area with the terminal body portions is large, thus obtaining a greater retaining force of the electric shock protection cover on the terminal body portions, making it less likely for the electric shock protection cover to detach from the terminal body portions.

[0032] By covering the periphery of the top portion of the terminal body with a peripheral covering, electric shock caused by contact between fingers or tools and the periphery of the terminal body, including the top surface, can be prevented. Furthermore, by using an inner anti-intrusion portion to prevent fingers or tools from entering between the opposing terminals, the anti-electric shock cover can also prevent electric shock caused by contact with the opposing inner surfaces of the terminal bodies.

[0033] (2) Preferably, an anti-detachment rib is provided that overlaps with the surface of the terminal body in the thickness direction. This is because the anti-detachment rib and the locking of the terminal body prevent the anti-electric shock cover from detaching relative to the terminal body in the thickness direction.

[0034] (3) Preferably, a locking protrusion is provided on the peripheral covering portion, the locking protrusion protruding toward the terminal body portion and locking onto the peripheral portion of the terminal body portion. This is because: by locking onto the peripheral portion of the terminal body portion with the locking protrusion, the movement of the anti-electric shock cover toward the top end of the terminal body portion is restricted, and the anti-electric shock cover is prevented from falling off toward the top end of the terminal.

[0035] (4) Preferably, an insertion hole is provided that penetrates the inner anti-intrusion portion. Accordingly, for example, when the surface of the counterpart terminal overlaps with the inner surface of the terminal body in the thickness direction, the counterpart terminal can be inserted through the insertion hole and overlap with the terminal body. In addition, for example, when the anti-touch finger rib protrudes between the counterpart terminals, the anti-touch finger rib can also be inserted through the insertion hole, and the anti-touch finger rib will not easily obstruct the connection between the terminal body and the counterpart terminal.

[0036] (5) Preferably, a pair of outer anti-intrusion portions are provided on the side opposite to the inner anti-intrusion portions of the pair of peripheral covering portions. This is because: for example, if there is a space on the outer side of the terminal body portion in the thickness direction where fingers or tools can be inserted, the outer anti-intrusion portions can prevent the insertion of fingers or tools into the space, and the anti-electric shock cover can also prevent electric shock caused by contact with the outer surface of the terminal body portion.

[0037] The connector with an anti-electric shock cover disclosed herein

[0038] (6) includes: a pair of terminal parts, each having a flat terminal body portion arranged in the thickness direction of the terminal body portion; and an anti-electric shock cover installed on the pair of terminal body portions, the anti-electric shock cover including: a pair of peripheral covering portions covering the periphery of the top portion of the pair of terminal body portions; and an inner anti-intrusion portion disposed between the pair of peripheral covering portions, the pair of peripheral covering portions being connected to each other, wherein, when the anti-electric shock cover is installed on the pair of terminal body portions, at least one surface in the thickness direction of the terminal body portion is exposed.

[0039] According to the connector with anti-electric shock cover disclosed herein, because the pair of peripheral covering portions of the anti-electric shock cover are connected to each other by the inner anti-intrusion portion, the anti-electric shock cover can be installed simultaneously on a pair of terminal body portions arranged together. Therefore, the number of operation steps required for installing the anti-electric shock cover is reduced. In addition, because the anti-electric shock cover is installed on a pair of terminal body portions together, the overlap area with the terminal body portions is large, so a larger retaining force of the anti-electric shock cover on the terminal body portions is obtained, and it is less likely that the anti-electric shock cover will fall off the terminal body portions.

[0040] By covering the periphery of the top portion of the terminal body with the periphery of the anti-electric shock cover, electric shock caused by contact between fingers or tools and the periphery of the terminal body, including the top surface, can be prevented. In addition, by using the anti-intrusion portion inside the anti-electric shock cover to prevent fingers or tools from entering between the opposing portions of a pair of terminal bodies, electric shock caused by contact with the opposing inner surfaces of a pair of terminal bodies can also be prevented.

[0041] <Details of the embodiments of this disclosure>

[0042] The following is a reference to the appendix. Figure 1 Specific examples of the anti-electric shock cover of this disclosure are described below. Furthermore, this disclosure is not limited to these examples, but is intended to include all modifications within the meaning and scope equivalent to the claims, as shown by the claims.

[0043] <Implementation Method 1>

[0044] The following is a reference. Figures 1 to 8 The following description will focus on Embodiment 1 of this disclosure. The anti-electric shock cover 10 of Embodiment 1 is, for example, an anti-electric shock cover installed on a pair of terminal body portions 42, 42 constituting a connector 30 with an anti-electric shock cover described later, to prevent electric shock caused by contact between fingers or tools and the terminal body portions 42, 42. In the following description, "above" will be referred to as... Figure 1 The Z direction in the middle, setting the so-called front as Figure 1 In the X direction, the so-called right side is set as Figure 1 The Y direction is explained in the figure. In addition, for multiple identical components, sometimes only some are labeled with reference numerals, while the reference numerals for other components are omitted.

[0045] <Anti-electric shock cover 10>

[0046] The electric shock protection cover 10 is formed of an electrically insulating material such as synthetic resin. For example... Figures 1 to 4 As shown, the anti-electric shock cover 10 has a pair of peripheral covering portions 12, 12 that cover the periphery of the top portion of the terminal body portions 42, 42 described later.

[0047] <Peripheral Covering Part 12>

[0048] The peripheral covering portion 12 is generally formed in a U-shape and integrally includes a top covering portion 14 that overlaps with the top surface of the terminal body portion 42, and a pair of side covering portions 16, 16 extending rearward from both ends in the vertical direction of the top covering portion 14.

[0049] <Top Covering Part 14>

[0050] The top cover portion 14 has a size and shape that can completely cover the top surface of the terminal body portion 42, which will be described later. In this embodiment, the top cover portion 14 extends linearly in the vertical direction in a quadrilateral cross section. The specific shape of the top cover portion 14 is not particularly limited. For example, when the top surface of the terminal body portion 42 extends in a curved manner, the top cover portion 14 can also be formed in a curved extending shape.

[0051] <Side edge covering part 16>

[0052] The side edge covering portion 16 has a size and shape that can cover the entire vertical side surface of the terminal body portion 42 described later. In this embodiment, the side edge covering portion 16 extends linearly in the front-back direction in a quadrilateral cross section. The specific shape of the side edge covering portion 16 is set according to the shape of the terminal body portion 42 described later. For example, when the side surface of the terminal body portion 42 extends in a curved manner, the side edge covering portion 16 can also be formed in a curved extending shape.

[0053] <Stuck protrusion 18>

[0054] Furthermore, a locking protrusion 18 protruding inward in the vertical direction is provided at the rear end of the side edge covering portion 16. The front side of the locking protrusion 18 is formed as an inclined surface that slopes forward in the vertical direction. In this embodiment, locking protrusions 18 are provided in each of the four side edge covering portions 16. In addition, the term "inward in the vertical direction" in the side edge covering portion 16 refers to the lower side in the side edge covering portion 16 provided at the upper end of the top covering portion 14, and refers to the upper side in the side edge covering portion 16 provided at the lower end of the top covering portion 14.

[0055] <Inner anti-intrusion section 20>

[0056] An inner anti-intrusion portion 20 is provided between a pair of peripheral covering portions 12, 12. The inner anti-intrusion portion 20 is generally formed as a plate extending in the left-right direction. The two ends of the inner anti-intrusion portion 20 in the left-right direction are integrally connected to the top covering portions 14, 14. Thus, the peripheral covering portions 12, 12 are connected to the top covering portions 14, 14 by the inner anti-intrusion portion 20 to form a whole.

[0057] <Insert Hole 22>

[0058] An insertion hole 22 is provided in the inner anti-intrusion section 20. The insertion hole 22 is provided through the front-to-back direction in a quadrilateral cross-section. Two insertion holes 22 are provided and arranged at a predetermined distance in the left-to-right direction. The inner anti-intrusion section 20 has a connecting portion 24 extending in the left-to-right direction on the outer side of the insertion hole 22 in the vertical direction, and a dividing portion 26 extending in the vertical direction between the two insertion holes 22, 22. In summary, the inner anti-intrusion section 20 has upper and lower connecting portions 24, 24 that connect the top covering portions 14, 14 to each other, and a dividing portion 26 that connects those connecting portions 24, 24 to each other. By providing the dividing portion 26, the space formed between the upper and lower connecting portions 24 is divided into two insertion holes 22, 22, and each insertion hole 22 is formed to a size that prevents the insertion of fingers, tools, etc.

[0059] <Anti-loosening rib 28>

[0060] A pair of anti-detachment ribs 28, 28 are provided in the top covering portion 14. The anti-detachment ribs 28 are formed as rods or plates extending from the top covering portion 14 toward the base end. In this embodiment, the anti-detachment ribs 28 extend rearward from two locations spaced apart in the vertical direction in the top covering portion 14. The anti-detachment ribs 28 are located inside the side edge covering portion 16 in the vertical direction and inside the side edge covering portion 16 in the horizontal direction.

[0061] Connector 30 with anti-electric shock cover

[0062] The electric shock protection cover 10 is formed in this structure Figure 5 As shown, the terminal bodies 42, 42 described later are installed in the connector 30 with an anti-electric shock cover. The connector 30 with the anti-electric shock cover has a structure in which a pair of terminal parts 34, 34 are assembled in the connector housing 32.

[0063] <Connector housing 32>

[0064] The connector housing 32 is constructed, for example, by an outer member and an inner metal member embedded in the outer member, the outer member being formed of an electrically insulating synthetic resin or the like. Figures 5-7 As shown, the connector housing 32 is generally formed as a bottomed square cylinder, having a square cylindrical portion 36 and a flange-shaped mounting piece 38 protruding outward from the rear end. Bolt holes 40 extending in the front-rear direction are formed at the four corners of the mounting piece 38. Furthermore, a pair of terminal insertion holes (not shown) extending in the front-rear direction are provided on the inner periphery of the cylindrical portion 36 in the connector housing 32.

[0065] <Terminal Component 34>

[0066] Terminal component 34 is formed of a conductive metallic material. For example... Figure 6 , 7As shown, the terminal part 34 includes a terminal body portion 42 formed in the shape of a flat plate. The terminal body portion 42 includes a groove 44. The groove 44 is provided with openings on the upper and lower surfaces of the terminal body portion 42 midway in the front-rear direction, and passes through the terminal body portion 42 in the left-right direction. The inner surface of the front side wall of the groove 44 is formed with a return structure that slopes forward as it leaves the opening in the vertical direction. For example, the inner surface of the front side wall of the groove 44 may also be formed in a stepped shape such that the width is narrower in the part closer to the opening than in the part farther from the opening.

[0067] A fixing part 46 and a wire connecting part 48 are provided on the rear side of the terminal body part 42. The fixing part 46 is continuously provided with the rear end of the terminal body part 42 and extends orthogonally to the terminal body part 42, and has a bolt hole 50 that passes through in the front-rear direction. The wire connecting part 48 is continuously provided with the rear end of the fixing part 46 and extends orthogonally relative to both the terminal body part 42 and the fixing part 46, and has a bolt hole 52 that passes through in the vertical direction.

[0068] Furthermore, since the pair of terminal parts 34, 34 are symmetrical in the left-right direction, the description of one terminal part 34 is provided, thus omitting the description of the other terminal part 34. Moreover, the term "symmetrical in shape" for the pair of terminal parts 34, 34 is not strictly limited to mathematical symmetry; they may have slight differences in the degree to which they can be considered approximately symmetrical overall. Specifically, for example, even if the presence, arrangement, number, and shape of the grooves 44 in the terminal parts 34, 34 differ, they can still be considered approximately symmetrical overall.

[0069] Assembly of terminal component 34 to connector housing 32

[0070] Terminal part 34 is fixed to connector housing 32. Specifically, the terminal part 34 is fixed to connector housing 32 by screwing a bolt 54, which passes through the bolt hole 50 of fixing part 46, into a nut part 56 provided with an opening on the rear surface of connector housing 32. Thus, by fixing the rear part of terminal part 34 to connector housing 32, the terminal body part 42 is positioned relative to connector housing 32, suppressing displacement such as vibration of the terminal body part 42. Therefore, the surrounding space considering vibration of the terminal body part 42 can be significantly narrowed compared to female terminals supported by conventional braids, enabling miniaturization of the connector 30 with an anti-electric shock cover. Furthermore, the method of fixing fixing part 46 to connector housing 32 is not particularly limited.

[0071] The terminal body portion 42 of the terminal component 34 is inserted into a terminal insertion hole (not shown) provided in the connector housing 32, such as... Figure 5As shown, the terminal body 42 protrudes forward from the inner periphery of the cylindrical portion 36 of the connector housing 32. A pair of terminal parts 34 are mounted in a left-right arrangement on the connector housing 32. With the terminal parts 34 mounted on the connector housing 32, the terminal bodies 42 are arranged approximately parallel in the left-right direction.

[0072] Furthermore, the connector housing 32 is fixed to a shielding shell (not shown), for example, using a bolt (not shown) inserted into the bolt hole 40. Additionally, a wire (not shown) is fitted to the wire connection portion 48 of the terminal part 34 via, for example, a crimp terminal.

[0073] Assembly of the 10-way terminal body 42 of the anti-electric shock cover

[0074] An anti-electric shock cover 10 is installed on the terminal body portion 42 of the terminal part 34 fixed to the connector housing 32. That is, the anti-electric shock cover 10 approaches the terminal body portion 42 from the front, such as... Figure 8 As shown, the peripheral covering portion 12 of the anti-electric shock cover 10 is installed overlapping the peripheral portion of the terminal body portion 42, including the top surface and the two side surfaces in the vertical direction. Furthermore, in Figure 8 For ease of viewing, only the anti-electric shock cover 10 and a pair of terminal parts 34, 34 are shown in the diagram.

[0075] The top cover 14 of the anti-electric shock cover 10 overlaps with the top surface of the terminal body 42 in a contacting or slightly separated state, and the side edge covers 16 overlap with the vertical side surfaces of the terminal body 42 in a contacting or slightly separated state. Additionally, the anti-detachment ribs 28 are inserted between the opposing terminals 42, 42, overlapping with the opposing inner surfaces of the terminal body 42, 42 in a contacting or slightly separated state. Thus, the anti-electric shock cover 10 overlaps with the top surface, the two vertical side surfaces, and the inner surface in the left-right direction of the terminal body 42, and is held at the top of the terminal body 42.

[0076] The anti-electric shock cover 10 is in contact with the top surface of the terminal body 42 via the peripheral covering portion 12 (top covering portion 14), thereby restricting its rearward displacement relative to the terminal body 42. The anti-electric shock cover 10 is in contact with the vertical side surface of the terminal body 42 via the peripheral covering portion 12 (side edge covering portion 16), thereby restricting its vertical displacement relative to the terminal body 42. The anti-electric shock cover 10 is in contact with the inner side surface of the terminal body 42 via the anti-detachment rib 28, thereby restricting its horizontal displacement relative to the terminal body 42. Thus, the anti-electric shock cover 10 is positioned relative to the terminal body 42 in the mounting direction and is prevented from detaching in the vertical and horizontal directions relative to the terminal body 42.

[0077] A locking protrusion 18 provided at the rear end of the side edge covering portion 16 is inserted into a groove 44 that opens at the periphery of the terminal body portion 42. Furthermore, when the anti-electric shock cover 10 is about to move forward relative to the terminal body portion 42, the locking protrusion 18 engages with the inner surface of the front side of the groove 44, thereby limiting the forward displacement of the anti-electric shock cover 10 relative to the terminal body portion 42. This prevents the anti-electric shock cover 10 from accidentally detaching from the terminal body portion 42 after being installed from the front.

[0078] Furthermore, the top cover 14, side edge cover 16, and anti-detachment rib 28 on the left side of the anti-electric shock cover 10 are installed on the left side of the terminal body 42, and the top cover 14, side edge cover 16, and anti-detachment rib 28 on the right side of the anti-electric shock cover 10 are installed on the right side of the terminal body 42. Here, the top cover 14, side edge cover 16, and anti-detachment rib 28 on the left side and the top cover 14, side edge cover 16, and anti-detachment rib 28 on the right side of the anti-electric shock cover 10 are integrally connected by the inner anti-intrusion part 20. As a result, the anti-electric shock cover 10 can be installed simultaneously with a pair of terminal bodies 42, 42. Compared with the existing method of installing anti-electric shock covers separately on a pair of terminal bodies 42, 42, the number of installation steps is reduced. Moreover, the overlapping area between one anti-electric shock cover 10 and the terminal bodies 42, 42 is increased, making installation easier and reducing the likelihood of accidental detachment.

[0079] In addition, the anti-detachment rib 28 on the left is connected to the terminal body 42 on the left, and the anti-detachment rib 28 on the right is connected to the terminal body 42 on the right, thereby limiting the displacement of the anti-electric shock cover 10 relative to the terminal body 42 to the left and right sides.

[0080] Furthermore, locking protrusions 18 are provided on the four mutually positioned side edge covering portions 16, and these locking protrusions 18 are inserted into the grooves 44. Therefore, the four sets of locking protrusions 18 and grooves 44 can more effectively prevent the electric shock cover 10 from falling forward from the terminal body portion 42. Moreover, by providing locking protrusions 18 on all four anti-detachment ribs 28, the resistance to detachment exerted by the locking of the locking protrusions 18 and the front inner surface of the grooves 44 acts well on the electric shock cover 10 to achieve a balanced resistance to detachment. As a result, undesirable situations such as concentrated load on specific side edge covering portions 16 and anti-detachment ribs 28 due to unbalanced forces acting on the electric shock cover 10 can be avoided.

[0081] The inner anti-intrusion portion 20 of the anti-electric shock cover 10 is disposed in front of the opposing space between a pair of terminal body portions 42, 42. Therefore, fingers or tools cannot be inserted into the space between the opposing terminal body portions 42, 42 from the front. As a result, the inner anti-intrusion portion 20 of the anti-electric shock cover 10 can also prevent electric shock caused by contact between fingers or tools and the inner surfaces of the terminal body portions 42 in the left-right direction.

[0082] The terminal body portions 42, 42, which are fitted with the anti-electric shock cover 10, are exposed because their outer surfaces in the left and right directions are formed to contact the opposite terminal (not shown). Therefore, they are not protected by the anti-electric shock cover 10. Figure 5 As shown, a cylindrical portion 36 of the connector housing 32 is disposed on the outer side of the terminal body portions 42 in the left and right directions. Furthermore, the distance between the top cover portion 14 of the anti-electric shock cover 10 and the cylindrical portion 36 is narrow enough to prevent the intrusion of fingers or tools. Thus, the cooperation of the top cover portion 14 and the cylindrical portion 36 prevents fingers or tools from contacting the left and right outer surfaces of the terminal body portion 42.

[0083] Furthermore, for example, when the connector 30 with the anti-electric shock cover is connected to a counterpart connector (not shown), the counterpart terminal (not shown) is inserted to the outside in the left-right direction of the anti-electric shock cover 10. Moreover, when the counterpart connector is provided with an anti-electric shock rib to prevent electric shock caused by touching the counterpart terminal, the anti-electric shock rib is inserted through the insertion holes 22, 22, thereby preventing the anti-electric shock rib hook from getting stuck on the anti-electric shock cover 10.

[0084] <Implementation Method 2>

[0085] Figure 9 Embodiment 2 is shown as another specific example. In the following description, the same reference numerals used in the figures for components and parts that are substantially the same as those in Embodiment 1 are omitted.

[0086] In Embodiment 2, the anti-electric shock cover 60 has locking protrusions 18 on the upper left and lower right side edge covering portions 16, respectively. In contrast, the lower left and upper right side edge covering portions 62 do not have locking protrusions 18, and are formed as a square plate or square rod extending in the front-back direction with a generally certain cross-sectional shape.

[0087] In this way, the locking protrusions 18 do not need to be provided on all the side edge coverings as in Embodiment 1. Furthermore, by providing the locking protrusions 18 only on the upper left and lower right side edge coverings 16 located diagonally, the forces acting on the anti-electric shock cover 60 are well balanced when the locking protrusions 18 engage with the grooves in the terminal body (not shown) to provide resistance against disengagement. Additionally, the pair of terminal body portions on which the anti-electric shock cover 60 is installed have grooves on the upper surface of the left terminal body portion and on the lower surface of the right terminal body portion.

[0088] Alternatively, it can be like this: Figure 10 As shown in the example of the electric shock cover 70, which is another specific example, a locking protrusion 18 is provided only on one side edge covering portion 16. However, in order to obtain sufficient resistance to detachment, it is desirable to provide locking protrusions 18 on two or more side edge covering portions 16. Alternatively, it is possible to provide locking protrusions 18 on two side edge covering portions 16 mounted on one terminal body, and not to provide locking protrusions on the two side edge covering portions 62 mounted on the other terminal body. However, from the viewpoint of balancing the forces acting on the electric shock cover and the difficulty of detachment, it is preferable to provide locking protrusions on the side edge covering portions mounted on each terminal body.

[0089] <Implementation Method 3>

[0090] Figure 11 Embodiment 3 is shown as another specific example. In the anti-electric shock cover 80 of Embodiment 3, the anti-detachment rib 82 is located on the outer side in the left-right direction, compared to the side edge covering portion 16. Furthermore, in... Figure 11 When the anti-electric shock cover 80 is installed on the terminal body parts 42, the anti-detachment rib 82 overlaps with the outer surface of each terminal body part 42 in the left and right directions.

[0091] In this way, even if the anti-detachment rib 82 overlaps with the outer surface of the terminal body 42 in the left and right directions, the anti-detachment rib 82 is connected to the terminal body 42, thereby positioning the anti-electric shock cover 80 in the left and right directions.

[0092] Furthermore, the anti-detachment ribs do not necessarily need to overlap with both terminal body portions 42; for example, they can overlap only with one terminal body portion 42. That is, the inner anti-detachment rib 28 and the outer anti-detachment rib 82 can be provided such that they overlap with the inner and outer surfaces in the left and right directions of one terminal body portion 42, respectively.

[0093] <Implementation Method 4>

[0094] Figure 12Embodiment 4 is shown as another specific example. The anti-electric shock cover 90 of Embodiment 4 includes outer anti-intrusion portions 92, 92. The outer anti-intrusion portion 92 is disposed on the side opposite to the inner anti-intrusion portion 20 in the left-right direction, i.e., the outer side, and is integrally formed with the top cover portion 14. The outer anti-intrusion portion 92 is generally formed in a square plate shape and has a through-hole 94 for a counterpart terminal in the front-back direction. A counterpart terminal (not shown) is inserted into the counterpart terminal through-hole 94, thereby allowing the terminal body (not shown) and the counterpart terminal to overlap and conduct in the left-right direction. The counterpart terminal through-hole 94 is formed with a cross-sectional shape and size that prevents fingers or hypothetical tools from passing through.

[0095] For example, in implementation method 1 (refer to) Figure 5 In this configuration, when the terminal body 42 and the cylindrical portion 36 of the connector housing 32 are significantly separated in the left-right direction, fingers and tools can be inserted between the opposing surfaces of the terminal body 42 and the cylindrical portion 36 in the left-right direction. However, when using the anti-electric shock cover 90 with an outer anti-intrusion portion 92 as described in Embodiment 4, the outer anti-intrusion portion 92 of the anti-electric shock cover 90 can also prevent fingers and tools from intruding into the outer left-right side of the terminal body on which the anti-electric shock cover 90 is installed.

[0096] <Other Implementation Methods>

[0097] The technology described in this specification is not limited to the embodiments described above and the accompanying drawings. For example, the following embodiments are also included in the technical scope of the technology described in this specification.

[0098] (1) In the embodiment described above, the inner anti-intrusion portion 20 is formed with two through holes 22, 22, but the shape of the inner anti-intrusion portion is not particularly limited. Specifically, for example, the inner anti-intrusion portion may also be formed as a plate or rod extending in the left-right direction, or the through holes 22 may not be provided.

[0099] (2) The anti-detachment rib can extend in the vertical direction by connecting the upper and lower side edge coverings 16, 16, or it can be formed into a cross shape that spans the top covering 14 and the side edge coverings 16.

[0100] (3) In the above embodiment, an example is shown where the outer surface of the counterpart terminal overlaps with the outer surface of the terminal body 42 in the left-right direction. However, for example, it is also possible to insert the counterpart terminal into the insertion hole 22 of the inner anti-intrusion portion 20, and the counterpart terminal overlaps with the inner surface of the terminal body 42 in the left-right direction. Furthermore, in embodiment 3, when the counterpart terminal inserted into the insertion hole 22 overlaps with the inner surface of the terminal body 42 in the left-right direction, the anti-detachment rib 82 can be provided in such a way that it completely covers the outer surface of the terminal body 42 in the left-right direction. In addition, in embodiment 4, when the counterpart terminal inserted into the insertion hole 22 overlaps with the inner surface of the terminal body 42 in the left-right direction, the counterpart terminal insertion hole 94 of the outer anti-intrusion portion 92 may not be present.

[0101] (4) When the other terminal is inserted between the anti-detachment ribs 28, the anti-detachment ribs 28 can also be used as a guide to guide the other terminal to the predetermined connection position by sliding it to the ground with the other terminal.

[0102] (5) When the terminal part has a flat terminal body, the specific structure can be appropriately modified. For example, such as Figure 13 As shown in the terminal part 100, the terminal body part 102 has a frame-shaped part 104 forming the outer peripheral end and a slit 106 passing through an elastic contact part 108 disposed on the inner peripheral side of the frame-shaped part 104.

[0103] The resilient contact portion 108 is formed by partially cutting and erecting a metal plate constituting the terminal body portion 102, and is integrally continuous with the frame portion 104 at its base end. The resilient contact portion 108 is formed in the shape of a leaf spring that can elastically deform in the thickness direction of the plate, allowing it to tilt relative to the frame portion 104 in the thickness direction through elastic deformation. A slit 106 formed between the frame portion 104 and the resilient contact portion 108 extends in a manner that surrounds the front side and the upper and lower sides of the resilient contact portion 108 in three directions.

[0104] At least a portion of the resilient contact portion 108 extends outward in the left-right direction, which is the plate thickness direction, from the base end (rear end) connected to the frame portion 104 toward the top end (front end) formed as a free end through the slit 106. As a result, the resilient contact portion 108 protrudes outward in the left-right direction relative to the frame portion 104, becoming the overlapping side that overlaps with the counterpart terminal (not shown).

[0105] The top 110 of the resilient contact portion 108, where the protrusion from the frame-shaped portion 104 in the plate thickness direction reaches its maximum, is located midway from the rear end toward the front end. The resilient contact portion 108 has a first inclined portion 112 that slopes in the plate thickness direction toward the overlapping side (not shown) of a counterpart terminal, and the amount of protrusion of the resilient contact portion 108 from the frame-shaped portion 104 in the plate thickness direction gradually increases from the rear end toward the top 110. Additionally, the resilient contact portion 108 has a second inclined portion 114 that slopes in the direction opposite to the overlapping side (not shown) of the counterpart terminal, and the amount of protrusion of the resilient contact portion 108 from the frame-shaped portion 104 in the plate thickness direction gradually decreases from the top 110 toward the front end. The top 110 of the resilient contact portion 108 is formed in a convex shape in a dot-like manner, and the top 110 protrudes more significantly relative to the frame-shaped portion 104.

[0106] When a terminal part 100 with this structure is used, the elastic contact portion 108 of the terminal body 102 elastically presses against the counterpart terminal (not shown), thus stably achieving contact between the terminal body 102 and the counterpart terminal. Furthermore, by cutting and erecting the terminal body 102, no additional parts are needed; a simple structure is sufficient to achieve the spring-like structure for pressing the terminal body 102 and the counterpart terminal against each other. Additionally, because the top portion of the elastic contact portion 108 has a second inclined portion 114, the counterpart terminal will not hook onto the elastic contact portion 108.

[0107] Furthermore, the terminal body 102 of the terminal component 100 has a frame-shaped portion 104 provided around the elastic contact portion 108, so that the peripheral covering portion of the anti-electric shock cover in embodiments 1 to 4 is mounted on the frame-shaped portion 104. The frame-shaped portion 104, which is the mounting portion of the anti-electric shock cover, will not deform or shift, and even if a movable portion such as the elastic contact portion 108 is provided on the terminal body 102, the anti-electric shock cover can be stably maintained in the mounting state relative to the terminal body 102.
