Description

Technical Field

[0001] The utility model relates to the technical field of electronic component production, in particular to an assembled terminal product. Background Art

[0002] Prior art inserts, such as those described in Publication No. CN211492610U, are manufactured by first positioning the terminals before injection molding them using an injection mold, with the plastic wrap encapsulating the terminals. Specifically, several positioning rods are sequentially inserted through the insert (i.e., the terminal) to position it. The entire insert is then placed into the injection mold and injection molded, ultimately creating the encapsulated insert. This method requires high process requirements and is not only time-consuming and labor-intensive, but also leads to high production costs. In particular, the insert must be precisely positioned using positioning rods before injection molding can begin. Any deviation in the insert's positioning can affect product quality.

DETAILED DESCRIPTION

[0025] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] like Figure 1 and Figure 2 As shown, a preferred embodiment of the present invention provides an assembled terminal product. The terminal 1 is primarily composed of an upper cover 2, a lower cover 3, and a plurality of terminals 1. The upper cover 2 and lower cover 3 are integrally injection-molded. The terminals 1 are of various types, each with a different shape. The terminals 1 are positioned by the lower cover 3, then pressed into place by the upper cover 2. Finally, the upper and lower covers 2 and 3 are securely connected to form the final product.

[0027] refer to Figure 3 The lower cover 3 is in the shape of a circular ring, and has an annular accommodating cavity on its upper surface, and has a plurality of positioning grooves, namely, first positioning grooves 302, in the accommodating cavity. The number of the first positioning grooves 302 is consistent with the number of the terminals 1. The first positioning grooves 302 are distributed along the circumferential direction of the lower cover 3, and when the number of the terminals 1 is large, the plurality of first positioning grooves 302 can be divided into multiple layers, that is, from the inner circle to the outer circle of the lower cover 3, it can be divided into multiple layers in sequence. Generally, there is at least one layer. In this embodiment, since the number of the terminals 1 is 10, three layers of first positioning grooves 302 are provided, and two layers of first positioning grooves 302 are provided in some local areas. The terminal 1 is placed in the accommodating cavity and is positioned by the first positioning groove 302.

[0028] The lower cover 3 also has a plurality of slots 301 circumferentially arranged, with adjacent slots 301 staggered vertically. Each slot 301 corresponds to the connecting end of each terminal 1. After a terminal 1 is positioned by the first positioning slot 302, the connecting end of the terminal 1, i.e., the first connecting end 11, bends and radially extends from the slot 301 on the lower cover 3 to facilitate connection with other components.

[0029] refer to Figure 4There are also multiple heat dissipation holes at the bottom of the lower cover 3 to dissipate heat for the terminal 1 product during operation.

[0030] like Figure 6 As shown, the bottom of the upper cover 2 is further provided with a plurality of second positioning grooves 202 and a plurality of positioning protrusions 21. The plurality of second positioning grooves 202 and the plurality of positioning protrusions 21 are arranged at intervals and are also distributed along the circumference of the lower cover 3. The positioning protrusions 21 are wedge-shaped. When the upper cover 2 is assembled with the lower cover 3, the positioning protrusions 21 can cooperate with the retaining grooves 301 to press the first connecting end 11 of the terminal 1 into the retaining grooves 301.

[0031] Since part of the upper side of the terminal 1 will protrude from the upper surface of the lower cover 3, the upwardly protruding part of the terminal 1 will be embedded in the second positioning groove 202 at the bottom of the upper cover 2 to ensure that the lower cover 3 and the upper cover 2 fit tightly together, while clamping and braking the upper side of the terminal 1 to prevent it from shaking at will.

[0032] like Figure 1 As shown, the positioning protrusion 21 abuts against the corresponding connecting end of the terminal 1 on the lower cover 3 to press the connecting end of the terminal 1 into the slot 301, and the part of the terminal 1 protruding from the upper surface of the lower cover 3 is embedded in the second positioning groove 202 to clamp and brake the upper side of the terminal 1.

[0033] like Figure 5 As shown, three positioning portions 22 are also provided on the upper surface of the upper cover 2, distributed circumferentially. Each positioning portion 22 is provided with a socket 221 that extends vertically through the upper and lower portions. Some terminals 1 have second connection ends 12, which bend vertically upward and pass through the sockets 221. The second connection ends 12 of two adjacent terminals 1 pass through the sockets 221 on the same positioning portion 22.

[0034] like Figure 3 、 Figure 5 As shown, after the terminal 1 is installed, the upper cover 2 and the lower cover 3 can be fixed. To this end, a plurality of positioning pins 31 are provided in the accommodating cavity of the lower cover 3, and a plurality of positioning holes 201 are provided at the bottom of the upper cover 2. The positioning holes 201 are through holes, and the positioning holes 201 correspond to the positioning pins 31 one by one.

[0035] When the upper cover 2 is close to the lower cover 3, the positioning pin 31 will pass through the positioning hole 201, and then the positioning pin 31 will be melted by ultrasound to rivet the upper cover 2 and the lower cover 3 together. In this embodiment, riveting is preferably used, but other connection methods such as bonding or clamping can also be used.

[0036] There is a sink on the upper side of the positioning hole 201 , so the melted portion of the positioning pin 31 will melt in the sink and eventually solidify, making the upper surface of the upper cover 2 relatively smooth.

[0037] In this embodiment, the terminal product is used to assemble ten terminals 1, so the characteristic shapes of the upper cover 2 and lower cover 3 are also designed based on the characteristics of the ten terminals 1. In other technical solutions, this assembly design can also be used to assemble six or four segments. Only the features of the upper cover 2 and lower cover 3 need to be adjusted. The assembly concept remains the same.

[0038] The above technical solutions only reflect the preferred technical solutions of the present utility model. Any changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present utility model and fall within the scope of protection of the present utility model.
