[0003] Ideally, the male electrical terminals should be provided with structural arrangements or features for overstress protection and guidance assistance to effectively protect and guide the male electrical terminals, thereby preventing undesirable deformation of the male electrical terminals during their mating with the connector assembly.

[0004] It is further desirable to ensure the orientation or polarity of the power terminals of the present invention and the corresponding connector assemblies maintained to properly mate with the power terminals.

[0005] It is also desirable that the present invention provides a method for ensuring effective clamping of a wire or cable through the public terminal of the present invention, the method comprising clamping or folding a pair of wire clamping tabs or core crimping wings and crimping them onto the inserted core portion of the wire or cable to prevent the wire or cable from sliding within or away from the public terminal.

[0006] It is also desirable that the present invention provides a method for ensuring effective clamping of a wire or cable through the public terminal of the present invention, the method comprising deforming, clamping or folding a pair of wire insulation clamping tabs or insulation crimping wings and crimping them onto the insulation portion into which the wire or cable is inserted, to prevent the wire or cable from sliding within or away from the public terminal. Summary of the Invention

[0007] The present invention provides a male electrical terminal for mating with a connector assembly, and typically includes a clamping or crimping portion, a body, and a blade.

[0008] The clamping or crimping portion includes a pair of wire insulation clamping tabs or insulating wings, and a pair of wire clamping tabs or core crimping wings. To ensure secure contact and clamping with the wire or cable, the pair of wire clamping tabs or core crimping wings includes multiple generally elongated notches and protruding members at their contact surfaces with the wire or cable. The pair of wire clamping tabs or core crimping wings are deformed, clamped, or folded and crimped onto the core of the wire or cable. Furthermore, the pair of wire insulation clamping tabs or insulating crimping wings are also deformed, clamped, or folded respectively and crimped onto the insulation of the wire or cable. The front portion of the clamping or crimping portion has a neck member that transitions into the body of the male terminal.

[0009] The main body is essentially box-shaped and typically includes a handle member. The handle member includes a rod member that locks the male terminal to the connector assembly. The rod member has a protruding member that, when bent, meets another protruding member extending from the main body. The two protruding members serve as overstress protection for the rod member; that is, they prevent or protect the rod member from deformation when the male terminal mates with the connector assembly.

[0010] A protruding guide member extends from and is attached to the shank member. The front end of the body also includes a tapered portion. The front end of the body also includes a panel shielding member for protecting the protruding guide member. When mated with a connector assembly, the tapered portion of the body, along with the protruding guide member and the panel guide member, facilitates the guidance of the male terminal of the invention. The front end of the body transitions into a blade having a tip that is also tapered. The body also includes a support member at either end.

[0011] The power terminal of the present invention also has an orientation or polarity for proper assembly into a corresponding connector assembly, the corresponding connector assembly having an orientation or polarity also maintained for proper assembly with the power terminal.

Detailed Implementation

[0028] Figure 1 shows a front top perspective view of a male electrical terminal generally referred to as reference numeral 1. The male electrical terminal 1 includes a clamping or crimping portion 3, a body 5, and a blade 7 integrally formed in the longitudinal direction. As discussed more fully later, the clamping or crimping portion 3 includes a pair of wire clamping tabs or core crimping wings 10, 11, and a pair of wire insulating clamping tabs or insulating crimping wings 13, 14. The body 5 includes a shank member 15 and a tapered portion 17 at its front end 20. The tapered portion 17 tapers towards the blade 7. Figure 1B The rear top perspective view of the male terminal 1 similarly shows the clamping or crimping portion 3, which includes a pair of wire clamping tabs or core crimping wings 10, 11 and a pair of wire insulation clamping tabs or insulation crimping wings 13, 14. Figure 1B The rear top perspective view of the public power terminal 1 in the middle is shown with Figure 1A Similar to the illustration, it also shows a foot member 15 and a tapered portion 17 at the front end 20 of the body 5. Preferably, the body 5 has a generally box-shaped or similar shape or form, but its shape or form is not limited thereto.

[0029] like Figure 2A and Figure 2B As shown, when viewed from the side view, the pair of wire insulation clamping tabs or insulating crimping wings 13, 14 are misaligned; that is, one of the wire insulation clamping tabs or insulating crimping wings 13, 14 is positioned closer to the wire clamping tabs or core crimping wings 10, 11 than the position of one of the wire insulation clamping tabs or insulating crimping wings 14. Also... Figure 2A and Figure 2B As shown, the clamping or pressing part 3 is integrally transitioned to the body 5 via the neck member 52, and the front end 20 of the body 5 is integrally transitioned to the blade 7. Figure 2A As shown, the handle member 15 includes a rod member 25, which has an unattached end 28 and an attached end 30. (As shown in...) Figure 2A and Figure 2B As can be seen further, the rod member 25 is shown here in a normal relaxed state.

[0030] The unattached end 28 of the rod member 25 preferably has a generally U-shaped form in cross-section along its width, but its form is not limited thereto (see [link]). Figure 5A The attachment end 30 of the rod member 25 preferably has a generally L-shaped form in cross-section along its width, but its form is not limited thereto (see...). Figure 8A ).

[0031] Furthermore, the rod member 25 has a protruding member 35 that joins another protruding member 37 extending from the body 5 (see [link]). Figure 2A Both protruding members 35 and 37 serve as overstress protection for the rod member 25. That is, when the rod member 25 is in a bent state, the protruding members 35 and 37 collide with each other. Therefore, this prevents or protects the rod member 25 from deformation when the male terminal 1 contacts or mates with the connector assembly 90, etc. (see...) Figure 14A Thus, the rod member 25 is operable to move substantially between a bent state and a normal relaxed state without deformation (see...). Figure 14A , Figure 14B When in Figure 2A and Figure 2B When viewed in the side view, the prominent components 35 and 37 are preferably rectangular, circular, trapezoidal, etc., but their shape or form is not limited to these.

[0032] During operation, when the male terminal 1 enters the connector assembly 90, the unattached end 28 of the rod member 25 is freely pushed downwards and moves from a normal relaxed state to a bent state (i.e., the protruding member 35 approaches another protruding member 37) (see...). Figure 14A When the male terminal 1 is fully inserted into the connector assembly 90, the unattached end 28 of the rod member 25 moves freely upward and returns to the normal relaxed state of the rod member 25 (i.e., the protruding member 35 moves away from the other protruding member 37) (see...). Figure 2A , Figure 14B Therefore, the unattached end 28 impacts a member (not shown) within the connector assembly 90, locking and securing the male terminal 1 within the connector assembly 90. This structural arrangement, in which the unattached end 28 of the rod member 25 impacts within the connector assembly, serves as a locking and securing feature for the male terminal 1.

[0033] Furthermore, when the male terminal 1 is fully inserted into the connector assembly 90, the clamping or crimping portion 3 is above the neck member 52 (see [link]). Figure 2A , 2BFurthermore, there is a space or transition area 50 between the online clamping tabs or core crimping wings 10, 11 and the body 5. The space or transition area 50 can be used to accommodate a terminal position assurance (TPA) device (not shown) for ensuring that the male terminal 1 remains locked, fixed and properly positioned within the connector assembly 90.

[0034] Figure 2A The diagram also shows a panel shielding member 40 at the front end 20 of the main body 5, which protrudes from a portion of the front end 20 of the main body. Figure 2B The tapered portion 17 of the front end 20 of the main body 5 is further shown. When the male terminal 1 mates with the connector assembly 90, the panel shielding member 40 and the tapered portion 17 (as discussed later) Figure 6A and Figure 6B The protruding guide member 53 shown helps guide and position the blade 7 and the body 5.

[0035] Figure 3A The image shows a top view of the clamping or pressing part 3, the main body 5, and the blade 7. Also, Figure 3A As shown, and as previously discussed, the pair of wire insulation clamping tabs or insulation crimping wings 13, 14 are misaligned, not directly aligned, or substantially opposite to each other. Furthermore, as previously stated, one of the wire insulation clamping tabs or insulation crimping wings 13 is positioned closer to the wire clamping tabs or core crimping wings 10, 11 of the male terminal 1 compared to the other wire insulation clamping tab or insulation crimping wing 14. This is to maximize the surface area of ​​the insulation portion 120 of the wire or cable 100, onto which the pair of wire insulation clamping tabs or insulation crimping wings 13, 14 connect and are mounted when clamped or crimped. As will be described later, another embodiment of the public terminal 1 may have a pair of foldable wire-insulated clamping tabs or insulating wings 213, 214 that are substantially directly opposite or substantially symmetrical (see below). Figure 12A and 12B ).like Figure 9 As shown, between a pair of wire insulation clamping tabs or insulation crimping wings 13, 14 is a base plate member 40, which is used to receive the insulation portion 120 of the wire or cable 100. After receiving the wire or cable 100, the pair of wire insulation clamping tabs or insulation crimping wings 13, 14 are deformed, clamped, or folded and crimped onto the insulation portion 120 of the wire or cable 100, but do not completely penetrate the insulation portion 120 or contact the core portion 110 (see [reference]). Figure 11 Additionally, the shape of the base plate member 40 is preferably substantially concave or circular (see...). Figure 8B ).

[0036] Figure 3A The image also shows a pair of wire clamping tabs or core crimping wings 10, 11 of the clamping or crimping portion 3. These wire clamping tabs or core crimping wings 10, 11 are substantially aligned with each other or substantially opposite each other (see also...). Figure 2A and Figure 2B The male terminal 1 is viewed from the side and is substantially symmetrical. Between a pair of wire clamping tabs or core crimping wings 10, 11 is a base plate member 45 having a plurality of notches 48. The shape of the base plate member 45 may be substantially flat (or substantially concave, circular, similar to the shape of the base plate member 40). As shown in more detail, the base plate 45 of the wire clamping tabs or core crimping wings 10, 11 is substantially flat in shape (as shown in more detail). Figure 4C As shown in the cross-sectional view), however, the base plate 45 can be substantially concave or circular in shape (similar to the shape of the base plate member 40) (as shown in the cross-sectional view). Figure 4D The shape is replaced by the cross-sectional view shown. Each of the plurality of notches 48 is substantially elongated in shape (as shown in the cross-sectional view). Figure 2A , Figure 2B , Figure 4A and Figure 4B (as shown in the diagram), but the shape of each of the notches 48 is not limited thereto. At least two notches 48 are possible, but at least three notches 48 are preferred. At least one protruding member 60 is possible, but at least two protruding members 60 are preferred. The combination of the notches 48 and the protruding members 60 forms a serrated pattern between the base plate member 45 and the pair of wire clamping tabs or core crimping wings 10, 11. This arrangement ensures that the base plate member 45 and the pair of wire clamping tabs or core crimping wings 10, 11 are aligned with the wire core 110 of the wire or cable 100 (see [reference]). Figure 9 A secure contact and clamping between the wire or cable 100 and the base plate member 45 is achieved. Once the wire core is inserted, the clamping or crimping portion 3 substantially clamps the wire core portion 110 of the wire or cable 100 so that the wire core cannot slip off from the base plate member 45 and the pair of wire clamping tabs or core crimping wings 10, 11; then, the pair of wire clamping tabs or core crimping wings 10, 11 are further deformed, clamped or folded, and crimped toward the base plate member 45 onto the wire core portion 110 of the wire or cable 100. This process ensures a secure contact and clamping between the clamping or crimping portion 3 of the male terminal 1 and the wire core portion 110 of the wire or cable 100, and prevents the wire core portion 110 of the wire or cable 100 from slipping off from the male terminal 1.

[0037] like Figure 10As shown, the core portion 110 subsequently conforms substantially to the shape of the deformed, clamped, or folded wire clamping tabs or core crimping wings 10, 11. That is, when a pair of wire clamping tabs or core crimping wings 10, 11 are deformed, clamped, or folded and crimped (the clamping or crimping process) onto the core portion 110 of the wire or cable 100, the protruding member 60 between the recesses 48 (see...) Figure 4A and Figure 4B ) and the protruding member 68 at each end (see also) Figure 4A and 4B It can be inserted into or pressed into the outer surface of the core portion 110 of the wire or cable 100.

[0038] like Figure 4A As further shown, each of the elongated notches 48 extends fully along the base plate member 45 between a pair of wire clamping tabs or core crimping wings 10, 11; and each of the elongated notches 48 also extends partially at its end 49 into the pair of wire clamping tabs or core crimping wings 10, 11, and substantially into the ends of the pair of wire clamping tabs or core crimping wings 10, 11 near end 49. Alternatively, as Figure 4B The additional embodiment shown has an end 49 of an elongated notch 48, each end 49 of which extends into a pair of wire clamping tabs or core crimping wings 10, 11 and exits substantially at the end or tip of the pair of wire clamping tabs or core crimping wings 10, 11 and extends into the end or tip of the pair of wire clamping tabs or core crimping wings 10, 11.

[0039] Figure 3B The image shows a bottom view of the clamping or crimping part 3 of the male electrical terminal 1, the main body 5, and the blade 7. The front end 20 of the main body 5 transitions to the blade 7, which is connected to and integral with the main body 5. Figure 3B ). Figure 3B The image also shows a pair of wire clamping tabs or core pressing wings 10, 11, which are substantially symmetrical and extend from the side of the base plate member 45 of the clamping or pressing portion 3, respectively. Figure 3B The embodiment of the male electrical terminal 1 shown illustrates a pair of wire-insulated clamping tabs or insulating crimping wings 13, 14, which are substantially misaligned, and when viewed from its side (see also...) Figure 2A and 2B It is also obvious when watching.

[0040] exist Figure 4A and Figure 4BEach of the figures also shows a front portion 51 of the clamping or crimping portion 3. The front portion 51 of the clamping or crimping portion 3 includes a space or transition area 50 above the neck member 52 and between the body 5 and the wire clamping tabs or core crimping wings 10, 11. The neck member 52 has a narrow tapered shape, tapering from the base plate member 45 and the wire clamping tabs or core crimping wings 10, 11 to the point where the neck member 52 meets the body 5. Furthermore, the narrow tapered shape of the neck member 52 of the front portion 51 allows the wire core portion 110 of the wire or cable 100 to remain seated or mounted within the base plate member 45 and prevents the wire core portion 110 of the wire or cable 100 from being integrally seated or mounted onto the neck member 52. Preferably, the narrow tapered form of the neck member 52 of the clamping or crimping portion 3 only allows the front portion of the wire core portion 110 of the wire or cable 100 to protrude into the neck member 52. In other words, the narrow tapered shape of the neck member 52 further prevents the core portion 110 from substantially entering the space or transition area 50. The transition area 50, as previously described, serves to accommodate a TPA device (not shown) to ensure that the male terminal 1 remains locked, secured, and correctly positioned when inserted into the connector assembly 90. Therefore, even if only the front portion of the core portion 110 enters or protrudes into the space or transition area 50, the core portion 110 will not interfere with or prevent the accommodation of the TPA device (not shown) therein.

[0041] Figure 5A The attached end 30 and unattached end 28 of the handle member 15 and the rod member 25 are shown. (As previously stated...) Figure 2A and Figure 2B The subject of discussion Figure 5A Also shown is a protruding member 35 of the unattached end 28 of the rod member 25, which is capable of striking another protruding member 37 extending from the body 5 to prevent the rod member 25 from deforming when the main terminal 1 mates with the connector assembly 90. The structural arrangement just described protects the rod member 25 from overstress (and thus prevents deformation of the rod member 25) when the rod member 25 bends as it enters the connector assembly 90. Figure 5A The panel shielding member 40 of the front end 20 of the main body 5 is also shown. Figure 6A and Figure 6B The panel shielding component 40 is discussed in more detail below.

[0042] Figure 5BThe diagram shows the front portion 69 and the rear portion 71 of the main body 5, each having a first support member 70 and a second support member 75. More specifically, the upper portion 69a at the front portion 69 of the main body 5 includes the first support member 70, while the upper portion 71a at the rear portion 71 of the main body 5 includes the second support member 75. A gap 76 separates the first support member 70 from the lower portion 80 of the main body 5. A set of gaps 78a and 78b separates the second support member 75 from the lower portion 80 of the main body 5. When the male electrical terminal 1 enters the connector assembly 90, the first support member 70 and the second support member 75 are elastically pushed downward toward the lower portion 80 of the main body 5 through the gaps 76 and 78a / 78b located between them, respectively. With the above structural arrangement, the first support member 70 and the second support member 75 provide the necessary elasticity to prevent the male electrical terminal 1 of the present invention from being excessively stressed and deformed when assembled into the connector assembly 90, thereby maintaining the polarity of the male terminal 1 (see [link to diagram]). Figure 14A and Figure 14B ).

[0043] exist Figure 6A and 6B The panel shielding member 40 is further shown in the document. The panel shielding member 40 is shown herein as extending from the side of the front end portion 20 of the body 5, but is not limited thereto. The panel shielding member 40 has an upper surface 55 and is shown here at an angle, wherein the lower end of the upper surface 55 faces the blade 7 and the upper end of the upper surface 55 faces the shank member 15.

[0044] Figure 6A and Figure 6B The diagram also shows a protruding guide member 53, which extends from and is attached to the handle member 15 of the body 5. The panel shielding member 40 protects the protruding guide member 53 from deformation during, for example, transport of the male electrical terminal 1, or preferably when the male electrical terminal 1 mates with and is inserted into the connector assembly 90. Figure 6B As shown more specifically, preferably, the upper surface 55, which extends generally along the panel shielding member 40, is substantially higher in height than or equal to the upper surface 58 of the protruding guide member 53 (see [reference]). Figure 6B In other words, preferably, the upper surface 55 of the panel guide member 40 is generally higher than or equal in height to the upper surface 58 of the protruding guide member 53. Similarly, the upper surface 58 of the protruding guide member 53 along the portion of the panel shield member 40 is lower than or equal to the upper surface 55 of the panel guide member 40, wherein the protruding guide member 53 tapers substantially downward from its attachment point with the foot member 15 and substantially gradually toward the front end portion 20.

[0045] like Figure 6A As shown, the front end 20 of the main body 5 transitions into the blade 7. Also as... Figure 7As shown, the blade 7 serves as the male contact of the male electrical terminal 1 within the male connector assembly 90, and can have a substantially rectangular, square, or other cross-sectional shape, but is not limited thereto. At the end of the blade 7 is a tapered tip 60, which may include a lower portion 62 substantially symmetrical to the upper portion 64, but the lower portion 62 and the upper portion 64 of the blade are not limited thereto, as long as the tip 60 of the blade 7 is in a narrow tapered form. The tapered tip 60 gradually tapers towards the end of the blade 7 at the end of the male electrical terminal 1, and further serves to prevent the blade 7 from being shortened or deformed.

[0046] Figure 8A This is a front view of the power terminal 1. The lower part 62 and upper part 64 of the blade 7 extending from the body 5 and the tip 60 are shown here. Figure 8A The upper surface 55 of the panel shielding member 40 is also shown, which has a higher or equal (preferably overall) height along the upper surface 58 of the protruding guide member 53, which extends from the foot member 15 of the body 5. Figure 8A The diagram also shows a pair of wire clamping tabs or core crimping wings 10, 11 and a pair of wire insulation clamping tabs or insulation crimping wings 13, 14, both extending from the clamping or crimping portion 3. Figure 8A Also visible is the gap 76 separating the first support member 70 from the lower part 80 of the main body 5, and similarly, the gap 78a below the second support member 75 (see also...). Figure 5B ).

[0047] Figure 8B A rear view of the public terminal 1 is shown. A pair of wire-insulating clamping tabs or insulating crimping wings 13, 14 extending from the corresponding sides of the base plate member 40 of the clamping or crimping portion 3 are shown. A pair of wire-insulating tabs or core crimping wings 10, 11 extending from the base plate member 45 are also shown. As part of the main body 5, as shown, the second support member 75 is located at the upper part 71a of the rear part 71 of the main body 5 (see also...). Figure 5B ). Figure 8B The image also shows the transition of the body 5 to the front end 20 of the blade 7, and the generally U-shaped unattached end 28 of the rod member 25.

[0048] Figure 9 An exemplary wire or cable 100 with a core portion 110 and an insulation portion 120 is shown, which is received by the male terminal 1 of the present invention. Although not limited thereto, the core portion 110 of the wire or cable 100 may be positioned in a serrated portion (formed by a notch 48 and protruding members 60, 68, see...) Figure 4A , Figure 4BOn the base plate member 45 and, as previously described, on a pair of wire clamping tabs or core crimping wings 10, 11, so that when the pair of wire clamping tabs or core crimping wings 10, 11 deform, clamp, or fold and crimp onto the wire core 110 of the wire or cable 100 (see See Figure 10 A firm contact is provided between the clamping or crimping portion 3 of the power terminal 1 and the core portion 110 of the wire or cable 100.

[0049] In addition, Figure 9 In this context, although not limited to this, the insulation portion 120 of the wire or cable 100 may be placed on the base plate member 40 of the clamping or crimping portion 3 of the power terminal 1 (see [reference]). Figure 4A , Figure 4B Furthermore, a pair of wire insulation clamping tabs or insulation crimping wings 13, 14 are clamped or folded and crimped onto the insulation portion 120 of the wire or cable 100.

[0050] As discussed (see...) Figure 4A and Figure 4B A pair of wire clamping tabs or core crimping wings 10, 11 are clamped or folded and crimped onto the wire core 110 of the wire or cable 100 (see...). Figure 10 And a pair of wire insulation clamping tabs or insulation crimping wings 13, 14 are clamped or folded and crimped onto the insulation portion 120 of the wire or cable 100 (see...). Figure 11 Then insert the male terminal 1 into the connector assembly 90, etc., such as... Figure 14A As shown.

[0051] exist Figure 10 The image shows in more detail the orientation of a pair of wire clamping tabs or core crimping wings 10, 11 folded toward each other and the base plate member 45, and deformed, clamped, or folded and crimped around and into the wire core portion 110 of the wire or cable 100. Here, the wire core portion 110 of the wire or cable 100 is substantially squeezed, deformed, compacted, and substantially surrounded by the pair of wire clamping tabs or core crimping wings 10, 11.

[0052] Figure 11 This illustrates how a pair of foldable wire insulation clamping tabs or insulating wings 13, 14 clamp or fold toward the base plate 40 and press against the insulation 120 of the wire or cable 100. (See diagram) Figure 11As further described in detail, when deformed, clamped, or folded and pressed onto the insulation 120 of the wire or cable 100, a gap A exists between a pair of misaligned foldable wire insulation clamping tabs or insulating wings of a pair of foldable wire insulation clamping tabs or insulating wings 13, 14. Alternatively, when clamped, folded, and pressed onto the insulation 120 of the wire or cable 100, the pair of foldable wire insulation clamping tabs or insulating wings 13, 14 may contact each other at one or more points (see, for example...). Figure 11 ).

[0053] As mentioned above, alternatively, in Figure 12A and 12B Another embodiment of a pair of foldable wire insulation clamping tabs or insulating wings 213, 214 is shown, wherein the pair of foldable wire insulation clamping tabs or insulating wings 213, 214 are substantially aligned and directly opposite each other, or substantially symmetrical to each other. The pair of foldable wire insulation clamping tabs or insulating wings 213, 214 extend from a substantially concave or circular base plate member 245. After insertion into the insulation portion 120 of the wire or cable 100, the pair of foldable wire insulation clamping tabs or insulating wings 213, 214 fold toward each other and toward the base plate 245 to pierce into the insulation portion 120 of the wire or cable 100, as... Figure 13 As shown. Figure 13 As further shown, the ends 220 and 221 of the pair of foldable wire insulation clamping tabs or insulation wings 213 and 214 are preferably inserted into portions of the insulation portion 120, but preferably not completely penetrate the insulation portion 120 of the wire or cable 100, or do not contact the core portion 110 of the wire or cable 100.

[0054] Figure 14A The diagram shows the male power terminal 1 in its pre-locked position, inserted into and passing through the connector assembly 90, etc., which is shown in the front view. Here, as understood, as the mating direction of the male power terminal 1 with the corresponding connector assembly 90, the blade is first inserted into and enters the connector assembly 90. Here, and before insertion begins, a pair of wire clamping tabs or core crimping wings 10, 11 deform, clamp, or fold and crimp onto the wire core 110 of the wire or cable 100, and a pair of wire insulation clamping tabs or insulation crimping wings 13, 14 clamp, fold, and crimp onto the insulation 120 of the wire or cable 100. As described above... Figure 8A As discussed in the front view of the public power terminal 1, it is also here. Figure 14AThe lower portion 62, upper portion 64, and tapered tip 60 of the blade 7 extending from the body 5 are shown. The upper surface 55 of the panel shielding member 40 is also shown, its height (preferably generally) being higher than or equal to the upper surface 58 of the protruding guide member 53. The protruding guide member 53 extends from the shank member 15 and is above the front end 20. The rod member 25 here is bent downwards by the connector assembly 90, which allows the body 5 of the male electrical terminal 1 to be inserted therein into the upper portion 90a and guided therein by the protruding guide member 53 (see [link to diagram]). Figure 14A ).

[0055] As mentioned above, and as Figure 14A As shown, during the insertion of the male electrical terminal 1 into the connector assembly 90, protruding members 35 and 37 (see example) Figure 2A and Figure 5A ) and the first and second support members 70, 75 (see example) Figure 5B To prevent or protect at least the rod member 25 and the male terminal 1 from excessive stress or deformation (see...) Figure 14A , Figure 14B Furthermore, as previously described, the tapered portion 17 of the front end portion 20 of the main body (see, for example) Figure 2A The prominent guide member 53 helps guide the male terminal 1 into the connector assembly 90 (see [link]). Figure 14A During the insertion of connector assembly 90 into the public terminal 1 (see...) Figure 14A The panel shielding member 40 protects the protruding guide member 53 (see example). Figure 6A and Figure 6B ).

[0056] Figure 14B The male electrical terminal is shown fully inserted into connector assembly 90. (As shown) Figure 14B As shown, the rod member 25 retracts upward to its normal relaxed state and is locked or secured at the unattached end 28 by a member (not shown) within the connector assembly 90. After or at this point, as previously described (see, for example...), Figure 2A The TPA device (not shown) is then housed in the space 50 above the neck member 52 located between the clamping or crimping part 3 and the body 5, ensuring that the male terminal 1 remains locked, fixed and properly positioned within the connector assembly 90.

[0057] exist Figure 14A and 14BThe upper portion 90a and lower portion 90b of the connector assembly 90 are shown in more detail. The orientation or polarity of the male terminal 1 of the present invention is such that when the male terminal 1 of the present invention is oriented, inserted, and assembled into the connector assembly 90, the blade 7 enters first, and the corresponding front end portion 20 further enters. The upper portion 69a at the front portion 69 and the upper portion 71a at the rear portion 71 of the body 5 are respectively received by the upper portion 90a of the connector assembly 90, while the lower portion 80 of the body 5 is respectively received by the lower portion 90b of the connector assembly 90. The upper portion 69a is guided into the upper portion 90a by a protruding guide member 52. The lower portion 80 is guided into the lower portion 90b by a tapered portion 17 and a panel shielding member 40. The male terminal 1 of the present invention... Figure 14A and Figure 14B The structural orientation or polarity shown causes the upper portions 69a and 71a of the body 5 to reside or fit within the narrower upper portion 90a. Furthermore, here, the upper portions 69a and 71a are offset to one side compared to the lower portion 80 of the body 5. The lower portion 80 is wider than the upper portions 69a and 71a and is located within the wider lower portion 90b of the male electrical terminal 1. However, this structural orientation or polarity of the male electrical terminal 1 of the present invention is not limited to this when inserted into or fitted into the connector assembly 90. That is, when the male electrical terminal 1 of the present invention is oriented, inserted, and fitted into the connector assembly 90, wherein the blade 7 enters first, and the corresponding front portion 20 further enters, it can cause the upper portions 69a and 71a of the body 5 and the upper portion 90a of the connector assembly 90 to be wider than the lower portion 80 of the body 5 and the lower portion 90b of the connector assembly 90. Similarly, the upper portions 69a and 71a can be centered or offset relative to the lower portion 80 of the body 5 when assembled in the mating direction, wherein the blade 7 enters the connector assembly 90 first. The polarity or orientation of the male terminal 1 and the connector assembly 90 will be substantially similar to allow them to be substantially assembled together.

[0058] While the foregoing description relates to preferred embodiments of the invention, it should be noted that other variations and modifications will be apparent to those skilled in the art and can be made without departing from the spirit or scope of the invention. Furthermore, features described in connection with one embodiment of the invention may be used in conjunction with other embodiments, even if not explicitly stated above.
