As shown in fig. 1, in a conventional injection molding process of a connector 200, a terminal of the connector is fixed in a pad 201, and then the terminal is placed in a mold, and an injection molded connector is manufactured through an injection molding process. The injection molding process needs to develop cushion pieces with various structures, so that the assembly procedures of the terminal and the cushion piece are increased, and the production cost of the product is increased.

The present invention provides a preferred embodiment of a fixing device for a connector terminal, which can solve the above technical problems.

Referring to fig. 2 and 3, wherein fig. 2 is a schematic structural diagram of a fixing device of a connector terminal according to an embodiment of the present invention, and fig. 3 is a schematic structural diagram of an elastic member in the fixing device of the connector terminal according to an embodiment of the present invention. The utility model provides a fixing device 100 of connector terminal 1 includes first body 3 and elastic component 2. The elastic member 2 is fixed on the first body 3, and when the terminal 1 is inserted into the fixing device 100 along the first body 3, the terminal 1 can be directly inserted into the gap between the elastic member 2 and the first body 3, so that the terminal can be fixed to complete installation, and the installation efficiency is improved.

Specifically, the first body 3 includes a first groove 31 and a first stopper groove 32. Wherein the first groove 31 is for accommodating the terminal 1 and extends in a direction in which the terminal 1 is inserted. More specifically, the number of the first grooves 31 is the same as the number of the terminals 1. For convenience of description, the direction in which the first groove 31 extends is a first direction X, and a direction in the width direction of the first body 3 perpendicular to the first direction is a second direction Y. The first stopper groove 32 is used to fix the elastic member 2. During manufacturing, the position of the first limiting groove 32 is only required to be arranged according to the length of the terminal 1 in the first direction X, and the production efficiency is improved.

Further, the elastic member 2 includes a fixing portion 21 and an elastic portion 22, wherein the fixing portion 21 is fixed in the first limiting groove 32 of the first body 3, and the elastic portion 22 is used for pressing the terminal 1 into the first groove 31.
