Description

Technical Field

[0001] The utility model belongs to the field of electric connectors, and in particular relates to an energy storage connector. Background Art

[0002] Connectors are a component that electronic engineers often come into contact with. Their function is to build a bridge between blocked or isolated circuits within a circuit, thereby enabling the flow of current or signals and enabling the circuit to achieve its intended function. Connectors are indispensable in electronic equipment.

[0003] The energy storage connector consists of a protective cover, a base, and terminal blocks, with the protective cover providing electrical protection. A Chinese patent document, "An Energy Storage Connector" (publication number CN218448598U, publication date February 3, 2023), discloses an energy storage connector comprising a housing, a base, and a pin. The base is provided with a slot on either side of its center, and a snap assembly is provided on either side of the housing. The snap assembly comprises a connecting plate, an elastic plate, and an upper protrusion. The top of the connecting plate is connected to the housing. The elastic plate is disposed on the outside of the connecting plate, and the bottom of the elastic plate is connected to the bottom of the connecting plate. The elastic plate is tilted outward from bottom to top, with a deformation gap between the top of the elastic plate and the connecting plate. The upper protrusion is provided on the outer side of the middle portion of the elastic plate. A lower protrusion is provided at the outer end of the top of the slot, extending inward. When the housing is connected to the base, the snap assembly is secured within the slot, with the top surface of the upper protrusion abutting against the bottom surface of the lower protrusion. The energy storage connector improves the convenience of connector installation and disassembly, and ensures the stability and strength of use.

[0004] In actual use, the energy storage connector's housing has an upper buckle on the outer side of the middle portion of the elastic plate, and a raised pressing portion on the upper outer side of the elastic plate. A lower buckle is provided at a corresponding position on the base. After the housing is installed in the base, the upper and lower buckles act as a limiter to securely connect the two parts. This energy storage connector has the following problems in actual use:

[0005] The upper convex buckle is arranged on the outer surface of the middle part of the elastic plate, and the upper convex buckle is a longer boss structure, which results in a shadow area between the upper convex buckle and the pressing part that requires core pulling. Therefore, a side core pulling device needs to be set on the mold for molding, which increases the manufacturing cost of the product.

[0006] In view of the problems existing in the above technologies, it is necessary to further improve the existing energy storage connectors. Summary of the Invention

[0007] The purpose of the utility model is to provide an energy storage connector that can reduce costs in response to the deficiencies of the existing technology.

[0008] The technical objectives of the present invention are achieved through the following technical solutions:

[0009] A energy storage connector, comprising a protective cover, a base and a wiring terminal; the wiring terminal is mounted on the lower end of the base, the bottom of the protective cover is detachably connected to the top of the base, and two opposite sides of the upper end of the base are provided with card slots; a V-shaped elastic arm that cooperates with the card slot is fixedly provided on the outer side of the protective cover; a connecting section of the V-shaped elastic arm is connected to the outer side of the protective cover, and a boss is provided on the elastic section of the V-shaped elastic arm away from the protective cover; a positioning groove that cooperates with the boss is provided in the card slot; a plurality of ribs are further provided on the side of the elastic section away from the protective cover, and the ribs are arranged at intervals on the upper side of the boss; the vertical spacing between the ribs is arranged to form a groove; the boss is arranged between two adjacent ribs, and the width of the boss is less than or equal to the width of the groove.

[0010] Preferably, the bosses are two bosses that are at the same level and symmetrically arranged; correspondingly, the positioning grooves are two symmetrically arranged positioning grooves.

[0011] Preferably, the positioning groove is a groove structure provided on the inner wall of the slot relative to the boss, and its overall height extends upward from the lower end of the slot to near the top of the slot.

[0012] Preferably, the boss is in a trapezoidal shape as a whole, and has an inclined portion inclined downward and outward.

[0013] Preferably, a guiding slope is provided on the top of the slot toward the inside.

[0014] Preferably, two groups of U-shaped guide columns are provided at the upper end of the base; each group of U-shaped guide columns consists of two and are symmetrically arranged on both sides of the card slot; accordingly, a U-shaped groove structure that cooperates with the U-shaped guide columns is provided at the lower end of the protective cover.

[0015] Preferably, the U-shaped guide column includes a draft portion and a straight portion arranged upper and lower.

[0016] Preferably, the overall height of the U-shaped guide column is greater than the height of the slot.

[0017] Preferably, the U-shaped groove structure includes a first U-shaped rib and a second U-shaped rib of equal wall thickness, the U-shaped top ends of the first U-shaped rib and the second U-shaped rib are respectively fixedly connected to the outer wall of the protective cover, and the inner and outer intervals between the first U-shaped rib and the second U-shaped rib are arranged to form a movable space for the up and down movement of the U-shaped guide column.

[0018] Preferably, the terminal includes a cylindrical portion, a limiting portion, an anti-rotation portion and a wiring portion arranged from top to bottom; the diameter of the cylindrical portion is smaller than the diameter of the limiting portion, the diameter of the anti-rotation portion is smaller than the diameter of the limiting portion, the diameter of the anti-rotation portion is equal to the diameter of the wiring portion, the anti-rotation portion is provided with an anti-rotation plane, and the wiring portion is provided with a wiring plane.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this invention, the vertical spacing between the ribs forms a groove; the boss is positioned between two adjacent ribs, and the boss width is less than or equal to the groove width. This technical measure eliminates the need for additional core pulling during mold forming. By placing inserts within the grooves, the boss can be formed by simply opening the static and dynamic molds, significantly reducing mold costs and, consequently, manufacturing costs.

[0021] 2. The positioning groove of this utility model is open at the bottom of the slot and extends upward to near the top of the slot. After the protective cover is pressed into the base, the boss falls into the positioning groove. The protective cover and base are fixed together by the fixed limit surface of the fixed limit groove and the corresponding dynamic limit surface of the boss. This groove structure is a localized glue reduction structure in the plane where it is located. It is simple to form and effectively ensures the strength of the entire plastic wall where the groove is located.

[0022] 3. The overall height of the U-shaped guide post of this utility model is greater than the height of the slot. The length of the U-shaped guide post is long enough so that even after the U-shaped guide post is inserted into the U-shaped slot, the boss of the V-shaped elastic arm has not yet contacted the positioning groove of the slot, enhancing the comfort of inserting the protective cover into the base. This technical measure can effectively improve the user experience.

[0023] 4. The U-shaped guide column of the present invention comprises a draft portion and a straight portion arranged above and below. The draft portion enhances the guiding performance, while the straight portion ensures the stability of the protective cover in the guide column.

[0024] 5. The U-shaped groove structure of this utility model comprises a first U-shaped rib and a second U-shaped rib of equal wall thickness. The top ends of the U-shaped ribs are fixedly connected to the outer wall of the protective cover. The first and second U-shaped ribs are spaced apart to create a space for the U-shaped guide post to move up and down. This technical measure ensures the overall structural strength of the protective cover while reducing the risk of product shrinkage. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] like Figure 1 — Figure 7 As shown, an energy storage connector includes a protective cover 1, a base 2 and a wiring terminal 3; the wiring terminal 3 is installed at the lower end of the base 2, the bottom of the protective cover 1 and the top of the base 2 are detachably connected, and a card slot 21 is provided on both sides of the upper end of the base 2; a V-shaped elastic arm 11 is fixedly provided on the outer side of the protective cover 1 to cooperate with the card slot 21; the connecting section 111 of the V-shaped elastic arm 11 is connected to the outer side of the protective cover 1, and the elastic section 112 of the V-shaped elastic arm 11 is provided with a boss 12 on the side away from the protective cover 1; a positioning groove 211 is provided in the card slot 21 to cooperate with the boss 12; a plurality of ribs 13 are also provided on the side of the elastic section 112 away from the protective cover 1, and the ribs 13 are arranged at intervals on the upper side of the boss 12; the vertical spacing between the ribs 13 is arranged to form a groove 14; the boss 12 is arranged between two adjacent ribs 13 and the width of the boss 12 is less than or equal to the width of the groove 14. By adopting this technical measure, the mold does not need additional core pulling during mold forming. By configuring inserts in the forming groove 14, the boss 12 can be formed by opening the static and dynamic molds, which greatly reduces the mold cost and thus reduces the manufacturing cost of the product during the production stage.

[0039] like Figure 1 As shown, the energy storage connector includes a protective cover 1, a base 2, and a terminal block 3. The protective cover 1, base 2, and terminal block 3 are arranged vertically, with the bottom of the protective cover 1 detachably connected to the top of the base 2; the terminal block 3 is installed at the lower end of the base 2.

[0040] like Figure 1 、 Figure 2 、 Figure 3 As shown, two sides of the upper end of the base 2 are provided with card slots 21. Specifically, the base 2 is provided with two card slots 21 in the middle of the upper end. The card slots 21 are U-shaped, and the U-shaped openings of the two card slots 21 are arranged opposite to each other.

[0041] In actual use, the outer side of the protective cover 1 is fixedly provided with a V-shaped elastic arm 11 that cooperates with the card slot 21; the connecting section 111 of the V-shaped elastic arm 11 is connected to the outer side of the protective cover 1, and the elastic section 112 of the V-shaped elastic arm 11 is provided with a boss 12 on the side away from the protective cover 1; a positioning groove 211 that cooperates with the boss 12 is provided in the card slot 21. Specifically, the card slot 21 on the corresponding base 2 of the protective cover 1 is fixedly provided with a V-shaped elastic arm 11 that cooperates with the card slot 21 on its outer side. The V-shaped elastic arm 11 includes a connecting section 111 and an elastic section 112; the connecting section 111 is connected to the outer side of the protective cover 1, and the elastic section 112 is provided with a boss 12 on the side away from the protective cover 1. Correspondingly, a positioning groove 211 that cooperates with the boss 12 is provided in the card slot 21. Specifically, the inner wall of the two card slots 21 facing the protective cover 1 is provided with a positioning groove 211 that cooperates with the boss 12.

[0042] like Figure 1 、 Figure 3 As shown, the elastic section 112 is further provided with a plurality of ribs 13 on the side away from the protective cover 1, and the ribs 13 are arranged at intervals on the upper side of the boss 12; the vertical spacing between the ribs 13 is arranged to form a groove 14; the boss 12 is arranged between two adjacent ribs 13 and the width of the boss 12 is less than or equal to the width of the groove 14.

[0043] Specifically, the boss 12 is generally arranged in the middle of the elastic section 112 on the side away from the protective cover 1, and the rib 13 is generally arranged in the upper part of the elastic section 112 on the side away from the protective cover 1, and the ribs 13 are spaced apart on the upper side of the boss 12. These ribs 13 are at the same horizontal height and the vertical spacing between the ribs 13 is set to form a groove 14. Among them, the boss 12 is arranged between two adjacent ribs 13 and the width of the boss 12 is less than or equal to the width of the groove 14. In actual use, an inclined surface is provided at the lower end of the rib 13. The rib 13 is an anti-slip boss, and its function is to prevent slipping when held in the hand. With this technical measure, during mold forming, the mold does not require additional core pulling. By configuring an insert in the molding groove 14, the static and dynamic molds can be opened to realize the molding of the boss 12, which greatly reduces the mold cost and thus reduces the manufacturing cost of the product during the production stage.

[0044] like Figure 2 、 Figure 3 、 Figure 4 As shown, the bosses 12 are two bosses 12 that are at the same level and symmetrically arranged; correspondingly, the positioning grooves 211 are two symmetrically arranged positioning grooves 211.

[0045] The positioning groove 211 is a recessed structure formed on the inner wall of the slot 21 relative to the boss 12. Its overall height extends from the lower end of the slot 21 to near the top of the slot 21. In actual use, after the protective cover 1 is pressed into the base 2, the boss 12 falls into the positioning groove 211. The fixed stop surface of the positioning groove 211 and the corresponding dynamic stop surface of the boss 12 securely connect the protective cover 1 to the base 2. This groove structure, a locally reduced-glue structure within the plane, is simple to form and effectively ensures the strength of the entire plastic wall where the positioning groove 211 is located.

[0046] like Figure 1 、 Figure 3 As shown, the boss 12 is trapezoidal in shape and has an inclined portion that tilts downward and outward. In actual use, the boss 12 is trapezoidal in shape and its lower end is an inclined surface. This technical measure facilitates the insertion of the protective cover 1.

[0047] like Figure 1 、 Figure 2 As shown, the top of the slot 21 is provided with a guide slope 212 toward the inside. This technical measure is adopted to facilitate the insertion of the protective cover 1.

[0048] like Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 As shown, the upper end of the base 2 is provided with two sets of U-shaped guide posts 22; each set of U-shaped guide posts 22 consists of two and are symmetrically arranged on both sides of the slot 21; accordingly, the lower end of the protective cover 1 is provided with a U-shaped groove structure 15 that cooperates with the U-shaped guide posts 22. U-shaped guide posts 22 are symmetrically arranged on both sides of the slot 21 at the upper end of the base 2.

[0049] The U-shaped guide column 22 includes a draft portion 222 and a straight portion 221 disposed above and below. Specifically, four U-shaped guide columns 22 are provided on the base 2, each comprising a lower straight portion 221 and an upper draft portion 222. The draft portion 222 enhances guidance, while the straight portion 221 ensures the stability of the protective cover 1 within the guide column. In actual use, the wall thickness of the U-shaped guide column 22 is substantially uniform, which ensures structural strength while reducing the risk of product shrinkage and enhancing the product's aesthetics.

[0050] like Figure 5 As shown, the overall height of the U-shaped guide post 22 is greater than the height of the slot 21. The length of the U-shaped guide post 22 is sufficiently long that, after the U-shaped guide post 22 has been inserted into the U-shaped slot structure 15, the boss 12 of the V-shaped elastic arm 11 has not yet contacted the positioning groove 211 of the slot 21, thereby enhancing the comfort of the protective cover 1 when inserted into the base 2. This technical measure can effectively improve the user experience.

[0051] like Figure 1 、 Figure 3 As shown, the U-shaped groove structure 15 includes a first U-shaped rib 151 and a second U-shaped rib 152 of equal wall thickness. The U-shaped top ends of the first and second U-shaped ribs 151, 152 are respectively fixedly connected to the outer wall of the protective cover 1. The first and second U-shaped ribs 151, 152 are spaced apart to form a space for the up and down movement of the U-shaped guide post 22. In actual use, the U-shaped groove structure 15 is provided on the protective cover 1 at a position corresponding to the U-shaped guide post 22. This U-shaped groove structure 15 cooperates with the U-shaped guide post 22 to provide guidance during installation of the protective cover 1. This U-shaped groove structure 15, including the first and second U-shaped ribs 151, 152 of equal wall thickness, ensures the overall structural strength of the protective cover 1 while reducing the risk of product shrinkage.

[0052] like Figure 7 As shown, the terminal block 3 includes, from top to bottom, a cylindrical portion 31, a limiting portion 32, an anti-rotation portion 33, and a wiring portion 34. The diameter of the cylindrical portion 31 is smaller than that of the limiting portion 32, the diameter of the anti-rotation portion 33 is smaller than that of the limiting portion 32, and the diameter of the anti-rotation portion 33 is equal to the diameter of the wiring portion 34. The anti-rotation portion 33 is provided with an anti-rotation plane 331, and the wiring portion 34 is provided with a wiring plane 341. In actual use, the diameters of the cylindrical portion 31 and the anti-rotation portion 33 are both smaller than those of the limiting portion 32, and the upper and lower sides of the limiting portion 32 form an upper limit surface and a lower limit surface, respectively. This structure can be machined or cold headed, which enhances the flexibility of the terminal manufacturing process and makes costs controllable.
