Description

Technical Field

[0001] This utility model relates to injection mold technology. Background Technology

[0002] Figure 1 and Figure 2 A perspective view and a cross-sectional view of a power connector 9 with two male plug terminals are shown. The power connector 9 includes a pair of male plug terminals 91, a pair of wires 92 connected to the male plug terminals 91, and a plastic housing 93. During manufacturing, an operator places the male plug terminals 91 (made of galvanized copper) connected to the wires 92 into an injection mold for injection molding, resulting in the power connector 9 as an assembly.

[0003] refer to Figure 3 and Figure 4 The existing mold for injection molding the aforementioned power connector 9 includes a slide block 1a, a slide block 2a, and an insert 3a. The slide block 1a has a first through hole 10a extending along the sliding direction of the slide block 1a. The first end of the slide block 2a is disposed in the first through hole 10a, and the second end of the slide block 2a extends out of the slide block 1a. The slide block 2a can slide synchronously with the slide block 1a, and the sliding direction is as follows... Figure 4 As shown by the arrow in the figure. The slider insert 2a is provided with a pair of second through holes 20a that extend along the sliding direction of the slider insert 2a, and a pair of inserts 3a (the material of the inserts 3a is galvanized copper) are respectively disposed in the pair of second through holes 20a.

[0004] The slide block 1a is detachably connected to the slider 6, and the connection method includes, but is not limited to, screw connection. The slide block 1a moves synchronously with the slider 6. Figure 4 The lower mold core 7 shown is mounted on the lower mold. It and the upper mold core (not shown in the figure) mounted on the upper mold form a cavity after mold closing, which is used to injection mold the plastic housing 93 of the power connector 9. The upper mold is provided with a slanted guide post, and the slider 6 is provided with a slanted hole (not shown in the figure) that mates with the slanted guide post. As the upper mold moves vertically upward away from the lower mold, the slanted guide post drives the slider 6 to move away from the lower mold core through the slanted hole (to the left of 4 in the figure). The slide block 1a, the slider insert 2a, and the insert 3a move together with the slider 6.

[0005] The use of existing slider insert assembly injection power connectors has the following disadvantages: Due to manual operation, when inserting a pair of male plug terminals 91 into a pair of second through holes 20a of the slider insert 2a, shaking or moving the wire 92 may cause slight movement of the male plug terminals 91. This results in inconsistent relative dimensions between the two male plug terminals 91 and the plastic housing 93 on a single part after injection molding (for example, the distance from the top of the two male plug terminals 91 to the end face 931 of the plastic housing 93 is inconsistent), which does not meet safety requirements (safety regulations require that the distance from the top of the two male plug terminals 91 to the end face 931 of the plastic housing 93 is approximately 2mm), thus affecting the product qualification rate. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a slider insert assembly for a power connector injection mold, which can ensure that the multiple male plug terminals of the power connector are reliably positioned after being inserted into the corresponding through holes of the slider insert, thereby ensuring that the relative dimensions of the multiple male plug terminals and the plastic shell of the power connector remain consistent after injection molding.

[0007] The present invention adopts the following technical solution:

[0008] A slider insert assembly for a power connector injection mold. The power connector includes a plastic housing, multiple male plug terminals, and multiple wires respectively connected to the multiple male plug terminals. The slider insert assembly includes a slide base, a slider insert, and multiple inserts, the number of which is the same as the number of male plug terminals. The slide base has a first through hole extending along the sliding direction of the slide base. The first end of the slider insert is disposed in the first through hole, and the second end of the slider insert extends out of the slide base. The slider insert can slide synchronously with the slide base. The slider insert has multiple second through holes extending along the sliding direction of the slider insert. The multiple inserts are respectively disposed in the multiple second through holes. The slider insert assembly also includes multiple female plug terminals, the same number as the multiple male plug terminals. The multiple female plug terminals are respectively disposed in the multiple second through holes and fixed to corresponding inserts for clamping corresponding male plug terminals.

[0009] Optionally, the power connector includes a pair of male plug terminals and two wires respectively connected to the pair of male plug terminals; the number of inserts, second through holes and female plug terminals are all a pair, the pair of inserts and the pair of female plug terminals are respectively disposed in the pair of second through holes, the pair of female plug terminals are respectively fixed to the pair of inserts, and the pair of female plug terminals are used to clamp the pair of male plug terminals.

[0010] This utility model has at least the following advantages:

[0011] This invention provides female plug terminals fixed to the insert in multiple second through holes of the slider insert. After the male plug terminal of the power socket is inserted into the through hole of the slider insert, it will clamp the male plug terminal, thereby preventing displacement of the male plug terminal due to human operation, ensuring reliable positioning of the male plug terminal, and thus ensuring that the relative dimensions of the multiple male plug terminals after injection molding are consistent with the plastic shell of the power socket, thereby improving the product injection molding yield.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] Please refer to Figures 5 to 8 According to an embodiment of the present invention, the slider insert assembly of the power connector injection mold includes a slide block 1, a slider insert 2, a pair of inserts 3, and a pair of female plug terminals 4.

[0021] The slide block 1 is detachably connected to the slider 6 of the injection mold of the power connector 9, and the connection method includes, but is not limited to, screw connection. The slide block 1 moves synchronously with the slider 6. The movement principle of the slider 6 has been described in the "Background Art" section of this application specification and will not be repeated here. Figure 5 The lower mold core 7 shown is disposed on the lower mold.

[0022] The slide block 1 has a first through hole 10 extending along the sliding direction of the slide block 1. The first end of the slider insert 2 is disposed in the first through hole 10, and the second end of the slider insert 2 extends out of the slide block 1. The slider insert 2 can slide synchronously with the slide block 1. In this embodiment, the bottom surface of the first end of the slider insert 2 is provided with a downwardly protruding first limiting protrusion 21; the opening of the first through hole 10 near the first end of the slider insert is provided with a first limiting groove 101 adapted to the first limiting protrusion 21, and a first stepped surface 102 is formed on the hole wall of the first through hole 10; the first limiting protrusion 21 extends into the first limiting groove 101 and abuts against the first stepped surface 102. At the same time, the first limiting protrusion 21 abuts against the slider 6, thereby preventing the slider insert 2 from moving axially.

[0023] The slider insert 2 has a pair of second through holes 20 extending along the sliding direction of the slider insert 2, and a pair of inserts 3 are respectively disposed in the pair of second through holes 20. A pair of female plug terminals 4 are respectively disposed in the pair of second through holes 20 and respectively fixed to the pair of inserts 3, for clamping a pair of male plug terminals 91 of the power connector 9.

[0024] The female plug terminal 4 includes a plate 4a, a terminal clamping part 4b, and a wire clamping part 4c. The terminal clamping part 4b and the wire clamping part 4c are respectively disposed at both ends of the plate 4a. The terminal clamping part 4a is used to clamp the male plug terminal 91, and the wire clamping part 4c is used to clamp the wire. The terminal clamping part 4b includes a pair of elastic clips 41, which are formed by bending the two opposite sides of the plate 4a towards each other. The gap between the pair of elastic clips 41 allows the male plug terminal to be inserted. The wire clamping part 4c includes a pair of inverted L-shaped elastic clips 41, which are integrally connected to the two opposite sides of the plate 4a and together with the plate 4a form a space for clamping the wire of the female plug terminal 4.

[0025] In this embodiment, the insert 3 includes an insert body 3a, a protruding arm portion 3b, and a second limiting protrusion portion 3c. The top surface of the insert body 3a is provided with a groove 30, and one end of the protruding arm portion 3b is connected to the end face 32 of the insert body adjacent to the second end of the slider insert. The wire clamping portion 4c extends into the groove 30 of the insert body, the rear end of the terminal clamping portion 4b (i.e., the rear end of a pair of elastic clips 41) clamps the protruding arm portion 3b, and the front end of the terminal clamping portion 4b (i.e., the front end of a pair of elastic clips 41) is used to clamp the male plug terminal 91. The second limiting protrusion 3c protrudes downward from the bottom surface of the end of the insert body near the first end of the slider insert; the second through hole 20 near the first end of the slider insert has a second limiting groove 202 adapted to the second limiting protrusion 3c, and a second stepped surface 204 is formed on the hole wall of the second through hole 20; the second limiting protrusion 3c extends into the second limiting groove 202 and abuts against the second stepped surface 204. At the same time, the second limiting protrusion 3c abuts against the slider 6, thereby preventing the insert 3 from moving axially.

[0026] Compared with the prior art, this embodiment adds a female plug terminal 4 to a pair of second through holes 20 in the slider insert 2. When the male plug terminal 91 of the power connector 9 is inserted into the second through hole 20 and abuts against the free end face 34 of the protruding arm 3b, the female plug terminal 4 can clamp the male plug terminal 91, so that the male plug terminal 91 will not move during manual operation. This ensures that the relative size of the pair of male plug terminals 91 and the plastic shell 93 of the power connector 9 is consistent after injection molding, thus improving the product injection molding yield.

[0027] The above embodiment uses an injection mold with two male plug terminals as an example. The number of male plug terminals is not limited to two; it can also be three, etc. In this case, the number of second through holes, inserts, and female plug terminals are the same as the number of male plug terminals. Multiple female plug terminals are respectively disposed in multiple second through holes and fixed to corresponding inserts for clamping the corresponding male plug terminals.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
