Along the first direction, the first insertion piece is inserted into the first plug-in hole, and the second insertion piece is inserted into the second plug-in hole.
[0011] The first direction, the second direction and the third direction are perpendicular to each other.
[0012] As a preferred technical scheme of the connector, a plurality of first protrusions are arranged on the outer side wall of the second insertion hole in the third direction on the same side of the second direction.
[0013] As a preferred technical scheme of the connector, the side wall of the shell is further provided with an insertion slot, and the terminal position assurance device is further provided with third protrusions on the opposite side walls in the second direction; when the first protrusions are inserted into the second sliding grooves, the third protrusions are inserted into the second sliding grooves; and when the first protrusions are located outside the second sliding grooves, the third protrusions are inserted into the insertion slot.
[0014] As a preferred technical scheme of the connector, the terminal position assurance device further comprises a third insertion piece, the third insertion piece is fixed to the fixing piece, in the third direction, the third insertion piece is located on the side opposite to the second insertion piece from the first insertion piece, a limiting groove is formed between the first insertion piece and the third insertion piece, and part of the shell is slidably inserted into the limiting groove in the first direction.
[0015] As a preferred technical scheme of the connector, the shell is provided with a sleeve coaxially arranged with the third insertion hole in the second direction.
[0016] As a preferred technical scheme of the connector, the sleeve is provided with a reinforcing rib, the third insertion piece is provided with a third sliding groove in the second direction, and the reinforcing rib can be inserted into the third sliding groove in the second direction.
[0017] As a preferred technical scheme of the connector, a plurality of third insertion holes are arranged, and the plurality of third insertion holes are staggered in the first direction.
[0018] As a preferred technical scheme of the connector, a sealing ring is arranged between the terminal position assurance device and the shell.
[0019] As a preferred technical scheme of the connector, the shell is provided with a folded edge, when the terminal position assurance device is inserted into the shell and the first protrusions are inserted into the second sliding grooves, the side wall of the terminal position assurance device on the side opposite to the shell in the first direction is flush with the edge of the folded edge.
[0020] An electrical device is also provided, comprising the above-mentioned connector.
[0021] The utility model has the advantages of:
[0022] This utility model provides a connector and an electrical device. The connector includes a housing and a terminal position guarantee. The housing has a first insertion hole and a second insertion hole along a first direction. The second insertion hole has a first protrusion and a first groove formed on its two opposite outer side walls in a second direction. The housing has a third insertion hole along the second direction for inserting a terminal. The terminal position guarantee includes a fixing member, a first insert, and a second insert. The first insert and the second insert are fixed by the fixing member. The fixing member has a second protrusion and a second groove on its two opposite side walls in the second direction. The second insert has a clearance hole along a third direction. Along the first direction, the first insert is inserted into the first insertion hole, and the second insert is inserted into the second insertion hole. The first direction, the second direction, and the third direction are perpendicular to each other.
[0023] For example, the housing and the terminal position guarantee are detachably connected. In use, the second protrusion of the terminal position guarantee is always inserted into the first slide groove and can move along the first direction within the first slide groove. The first slide groove includes at least one side wall in the first direction, which can limit the movement range of the second protrusion in the first direction, preventing the second protrusion from falling out of the first slide groove, thereby maintaining the connection between the terminal position guarantee and the housing. The terminal position guarantee has a pre-locked position and a final locked position relative to the housing. The terminal position guarantee can switch between the pre-locked position and the final locked position by moving relative to the housing along the first direction. When in the pre-locked position, the first protrusion is located outside the second slide groove, and the terminal can be inserted into the third slide groove along the third direction. When the terminal needs to be locked in the insertion state of the terminal and the housing, the terminal position guarantor moves from the pre-locked position to the final locked position. During the movement, one side wall of the clearance hole of the second insert is inserted into the terminal, so that the terminal cannot exit the clearance hole and the third insertion hole in the third direction, thereby maintaining the insertion state of the terminal and the housing. At the same time, the limiting part abuts against the first protrusion, and the limiting part and / or the first protrusion undergo elastic deformation to avoid the first protrusion, so that the first protrusion can pass through the limiting part and enter the second slide groove. At the same time, due to the blocking of the limiting part, the first protrusion is difficult to exit the second slide groove in the first direction to form a lock, so as to maintain the position lock of the terminal position guarantor and the housing.
[0024] Furthermore, during the insertion and removal of terminals, the terminal position guarantor is in the pre-locked position, providing relative space to the housing. The housing always exerts a force relative to the terminal position guarantor in a third direction, which can easily cause the second insert to bend. To maintain a reliable connection between the terminal position guarantor and the housing, the terminal position guarantor also includes a first insert. The first insert and the second insert are spaced apart in a third direction. The first insert is inserted into the first insertion hole of the housing. Thus, the first insert and the second insert are respectively inserted into the first insertion hole and the second insertion hole of the housing. This not only increases the contact area to form a limit, but the first insert can also share the force exerted by the housing on the second insert in a third direction, thereby protecting the second insert and extending its service life.

[0045] like Figures 1 to 10 As shown, this utility model provides a connector, including a housing 100 and a terminal position guarantee 200. The housing 100 has a first insertion hole 110 and a second insertion hole 120 along the first direction X. The second insertion hole 120 has a first protrusion 130 and a first groove 140 formed on the two opposite outer side walls in the second direction Y. The housing 100 has a third insertion hole 150 along the second direction Y. The third insertion hole 150 is used to insert a terminal. The terminal position guarantee 200 includes a fixing member 210, a first insert 220 and a second insert 230. The first insert 220 and the second insert 230 are fixed by the fixing member 210. The fixing member 210 has a second protrusion 240 and a second groove 250 on the two opposite side walls in the second direction Y. The second insert 230 has a clearance hole 231 along the third direction Z. Along the first direction X, the first insert 220 is inserted into the first insertion hole 110 and the second insert 230 is inserted into the second insertion hole 120. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.
[0046] In use, the second protrusion 240 is inserted into the first slide groove 140, and the terminal is inserted into the clearance hole 231. When the first protrusion 130 is inserted into the second slide groove 250, the side wall of the clearance hole 231 is connected to the terminal along the first direction X.
[0047] For example, the housing 100 is detachably connected to the terminal position guarantee 200. In use, the second protrusion 240 of the terminal position guarantee 200 is always inserted into the first slide groove 140 and can move within the first slide groove 140 along the first direction X. The first slide groove 140 includes at least one side wall in the first direction X, which can limit the movement range of the second protrusion 240 in the first direction X, preventing the second protrusion 240 from falling out of the first slide groove 140, thereby maintaining the connection relationship between the terminal position guarantee 200 and the housing 100. The terminal position guarantee 200 includes a pre-lock position and a final lock position relative to the housing 100. The terminal position guarantee 200 can switch between the pre-lock position and the final lock position by moving relative to the housing 100 along the first direction X. When in the pre-lock position, the first protrusion 130 is located outside the second slide groove 250, and the terminal can be inserted into the third slide groove 250 along the third direction Z. When the terminal needs to be locked in the insertion state of the terminal and the housing 100, the terminal position guarantor 200 moves from the pre-locked position to the final locked position. During the movement, one side wall of the clearance hole 231 of the second insert 230 is inserted into the terminal, so that the terminal cannot exit the clearance hole 231 and the third insertion hole 150 along the third direction Z, thereby maintaining the insertion state of the terminal and the housing 100. At the same time, the limiting part abuts against the first protrusion 130, and the limiting part and / or the first protrusion 130 undergo elastic deformation to avoid, so that the first protrusion 130 can pass over the limiting part and enter the second slide groove 250. At the same time, due to the blocking of the limiting part, the first protrusion 130 is difficult to exit the second slide groove 250 along the first direction X to form a lock, so as to maintain the position lock of the terminal position guarantor 200 and the housing 100.
[0048] Furthermore, during the insertion and removal of terminals, the terminal position retainer 200 is in the pre-locked position, providing relative space to the housing 100. The housing 100 always exerts a force relative to the terminal position retainer 200 in the third direction (Z), which can easily cause the second insert 230 to bend. To maintain a secure connection between the terminal position retainer 200 and the housing 100, the terminal position retainer 200 also includes a first insert 220. The first insert 220 and the second insert 230 are spaced apart in the third direction (Z). The first insert 220 is inserted into the first insertion hole 110 of the housing 100. Thus, the first insert 220 and the second insert 230 are respectively inserted into the first insertion hole 110 and the second insertion hole 120 of the housing 100. This not only increases the contact area to form a limit, but the first insert 220 can also share the force exerted by the housing 100 on the second insert 230 in the third direction (Z), thereby protecting the second insert 230 and extending its service life.
[0049] It should be noted that after the terminal is inserted into the housing 100, the terminal's spring clip can unfold and snap into the housing 100. The terminal position guarantor 200 is used to further ensure the stability of the connection between the terminal and the housing 100.
[0050] Preferably, the first protrusion 130 is provided with a guide surface in the first direction X, and the first protrusion 130 can enter or exit the second slide groove 250 along the guide surface.
[0051] Preferably, the second protrusion 240 is provided with a guide surface in the first direction X, and the second protrusion 240 can enter or exit the first groove 140 along the guide surface.
[0052] Preferably, the limiting portion of the second slide groove 250 is provided with a guide surface in the first direction X, so that the first protrusion 130 can enter or exit the second slide groove 250.
[0053] Optionally, on the same side of the second direction Y, the outer wall of the second insertion hole 120 is provided with a plurality of first protrusions 130 in the third direction Z, and the terminal position guarantor 200 is provided with a plurality of second grooves 250.
[0054] For example, on the same side of the second direction Y, the outer wall of the housing 100 is provided with a first protrusion A and a first protrusion B. The first protrusion A and the first protrusion B are arranged along the third direction Z. The terminal position guarantor 200 is provided with a second groove A and a second groove B on the same side of the second direction Y. The second groove A and the second groove B are arranged along the third direction Z, and the second groove A and the second groove B are both parallel to the first direction X. When the terminal position guarantor 200 and the housing 100 are in the final locked position, the first protrusion A is inserted into the second groove A, and the first protrusion B is inserted into the second groove B. Thus, by setting multiple first protrusions 130 and corresponding second slide grooves 250, the force-bearing area can be dispersed, reducing the force intensity of the limiting part of each first protrusion 130 and the corresponding second slide groove 250. This not only extends the service life of the limiting parts of the first protrusions 130 and the second slide grooves 250, but also makes the connection between the terminal position guarantor 200 and the housing 100 in the final locked position more tight and reliable due to the increased connection along the third direction Z.
[0055] Optionally, the side wall of the housing 100 is also provided with a slot 160, and the terminal position guarantor 200 is also provided with a third protrusion on the opposite side walls in the second direction Y. When the first protrusion 130 is inserted into the second slide groove 250, the third protrusion is inserted into the second slide groove 250. When the first protrusion 130 is located outside the second slide groove 250, the third protrusion is inserted into the slot 160.
[0056] For example, the second slide 250 includes a first slide 141 and a second slide 142. The first slide 141 and the second slide 142 are parallel and arranged along a third direction Z. In the first direction X, the length of the first slide 141 is greater than the length of the second slide 142. The slot 160 is located on one side of the second slide 142 in the first direction X, and the slot 160 is close to the edge of the housing 100 in the first direction X relative to the second slide 142. The slot 160 includes two opposite side walls in the first direction X. A second protrusion 240 is slidably inserted into the first slide 141 along the first direction X, and a third protrusion is slidably inserted into the second slide 141 along the first direction X. 2 or slot 160. When the terminal position guarantor 200 is pre-locked with the housing 100, the second protrusion 240 is inserted into the first slide rail 141, and the third protrusion is inserted into the second slide rail 142 or slot 160. When it is necessary to insert or remove the terminal, in order to prevent the terminal position guarantor 200 from sliding relative to the housing 100 in the first direction X and causing interference to the insertion or removal of the terminal, the third protrusion is inserted into the slot 160. The opposite side walls of the slot 160 in the first direction X can restrict the movement of the terminal position guarantor 200 relative to the housing 100 in the first direction X, and can also prevent the terminal position guarantor 200 from disengaging from the housing 100. The third protrusion can undergo elastic deformation. When the terminal position guarantor 200 moves from the pre-lock position to the final lock position, the third protrusion moves from the slot 160 into the second slide groove 250 along the first direction X. When the third protrusion abuts against the side wall of the slot 160 in the first direction X, the third protrusion can deform to avoid it and then exit from the slot 160 until it moves into the second slide groove 250. The third protrusion then restores its deformation and is inserted into the second slide groove 250.
[0057] Furthermore, the third protrusion is provided with guide surfaces on its opposite side walls in the first direction X. The third protrusion can exit from the second slide groove 250 along one of the guide surfaces and exit from the slot 160 along the other guide surface.
[0058] Furthermore, the second slide 142 of the second slide groove 250 is provided with a guide surface on the side edge adjacent to the slot 160 in the first direction X, and the third protrusion can exit or enter the second slide 142 along the guide surface.
[0059] Furthermore, guide surfaces are provided on the opposite side walls of the slot 160 in the first direction X, and the third protrusion can enter or exit the slot 160 along the guide surfaces.
[0060] Optionally, the terminal position guarantor 200 further includes a third insert 260, which is fixed to the fixing member 210. In the third direction Z, the third insert 260 is located on the side of the first insert 220 opposite to the second insert 230. A limiting groove 280 is formed between the first insert 220 and the third insert 260, and part of the housing 100 is slidably inserted into the limiting groove 280 along the first direction X. With this configuration, the terminal position guarantor 200 is inserted into the housing 100 through the first insert 220, the second insert 230, and the third insert 260, forming an arc-shaped connection between the terminal position guarantor 200 and the housing 100. This not only increases the contact area between the terminal position guarantor 200 and the housing 100, enhancing the connection stability, but also reduces the force borne by each of the first insert 220, the second insert 230, and the third insert 260, thereby improving their service life.
[0061] It should be noted that the bow shape is the shape projected along the second direction Y.
[0062] Optionally, the housing 100 is provided with a sleeve 170 along the second direction Y, and the sleeve 170 is coaxially arranged with the third insertion hole 150. In use, after the terminal passes through the sleeve 170, it is inserted into the third insertion hole 150. The sleeve 170 can straighten and maintain the relative position of the terminal and the housing 100, reduce the swing of the terminal relative to the housing 100, and also protect the terminal.
[0063] Optionally, the sleeve 170 is provided with a reinforcing rib 180, and the third insert 260 is provided with a third groove 270 along the second direction Y, so that the reinforcing rib 180 can be inserted into the third groove 270 along the second direction Y.
[0064] For example, the housing 100 also includes a housing body, and the first insertion hole 110, the second insertion hole 120 and the third insertion hole 150 are all opened in the housing body. The sleeve 170 is fixedly connected to the housing body. Since the sleeve 170 forms a cantilever structure, in order to keep the connection between the sleeve 170 and the housing body firm, a reinforcing rib 180 is provided at the connection between the sleeve 170 and the housing body.
[0065] Furthermore, in order to limit the swing of the terminal position guarantor 200 and the housing 100 along the second direction Y, a third insert 260 is formed in the third slide groove 270. The third slide groove 270 includes a third slide 271 and a fourth slide 272. The third slide 271 and the fourth slide 272 are connected. The reinforcing rib 180 can be inserted into the fourth slide 272 through the third slide 271. The sleeve 170 can be inserted into the third slide 271. The side walls of the fourth slide 272 on opposite sides in the second direction Y limit the reinforcing rib 180. The side walls of the third slide 271 limit the sleeve 170. In this way, the terminal position guarantor 200 and the housing 100 are limited in the second direction Y.
[0066] Optionally, multiple third insertion holes 150 are provided, and the multiple third insertion holes 150 are staggered along the first direction X. This arrangement can reduce the length dimension of the housing 100 in the second direction Y.
[0067] Optionally, a sealing ring 300 is provided between the terminal position guarantor 200 and the housing 100.
[0068] For example, the terminal position guarantor 200 has a sealing ring 300 fixed to its fixing member 210. When the terminal position guarantor 200 is inserted into the housing 100, the sealing ring 300 can fill the connection gap between the terminal position guarantor 200 and the housing 100, thereby achieving the effect of dustproof and waterproof.
[0069] Optionally, the housing 100 is provided with a folded edge 190. When the terminal position guarantor 200 is inserted into the housing 100 and the first protrusion 130 is inserted into the second slide groove 250, the side wall of the terminal position guarantor 200 on the side opposite to the housing 100 in the first direction X is flush with the edge of the folded edge 190.
[0070] For example, the folded edge 190 includes a first folded edge 191, a second folded edge 192, and a third folded edge 193. Two first folded edges 191 and 192 are each provided, symmetrically arranged in the second direction Y. The first folded edge 191 extends along the third direction Z. One end of the second folded edge 192 is connected to the first folded edge 191, and the second folded edge 192 extends along the first direction X. The third folded edge 193 is formed on the edge of the housing 100 in the first direction X, connecting the two second folded edges 192. When the terminal position retainer 200 is in the final locked position with the housing 100, the edge of the fixing member 210 is in contact with the first folded edge 191, the second folded edge 192, and the third folded edge 193. This not only results in a neat appearance but also reduces the possibility of the terminal position retainer 200 separating from the housing 100 due to accidental contact.
[0071] Furthermore, when it is necessary to remove the terminal from the housing 100, the terminal position retainer 200 must first be removed from the housing 100, and then the terminal spring is moved by a tool so that the spring is retracted and the terminal can be removed from the third insertion hole 150.
[0072] An electrical device is also provided, including the connector described above. Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
