It should be noted that, as shown in fig. 3 and 4, the clamping grooves 1042 are communicated with the terminal insertion holes 105 on the second body 102, and the l-shaped grooves 1043 are communicated with the terminal insertion holes 105 on the first body 101; after the metal terminals 106 are mounted in the terminal insertion holes 105, the metal terminals 106 in the terminal insertion holes 105 of the first body 101 abut against the lower ends of the L-shaped plates 1041, and the metal terminals 106 in the terminal insertion holes 105 of the second body 102 abut against the lower ends of the clamping blocks 1044. Through the above mechanism, the metal terminal 106 in the first body 101 and the metal terminal 106 in the second body 102 are both limited in the terminal insertion hole 105, so that the anti-falling effect of the metal terminal 106 is realized, and the stability of the metal terminal 106 is improved.
In order to further improve the installation stability between the first main body 101 and the second main body 102, the installation structure further comprises an insertion block 4 arranged at the inner end of the second main body 102, an insertion hole 5 arranged on the first main body 101, and an insertion opening 6 arranged at the outer end of the L-shaped groove 1043; the L-shaped plate 1041 is arranged along the width direction of the second main body 102, the outer end of the L-shaped plate 1041 is a closed end 7, the inner end of the L-shaped plate 1041 is an open end 8, the plug-in block 4 is arranged on the open end 8, the plug-in block 4 is arranged in the plug-in hole 5, and the closed end 7 is arranged on the plug socket 6 in a clamping manner. The inserting block 4 and the inserting hole 5 are inserted, so that the inserting and fixing effects are improved; the coupling outer ends of the first body 101 and the second body 102 are flush by the fitting of the closed end 7 and the socket 6.
Based on the above structure, the structure of the wire end connecting portion 1 of the existing connector is improved to be divided into the first main body 101 and the second main body 102 inserted into the first main body 101, and by setting the clamping mechanism 104, the metal terminal 106 inserted into the terminal insertion hole 105 can be limited, especially, the metal terminal 106 in the terminal insertion hole 105 of the first main body 101 abuts against the lower end of the L-shaped plate 1041, and the metal terminal 106 in the terminal insertion hole 105 of the second main body 102 abuts against the lower end of the clamping block 1044, so that the metal terminal 106 is stably installed in the terminal insertion hole 105, and the metal terminal 106 is effectively prevented from being disengaged.
In order to further improve the installation stability of the metal terminal 106 in the terminal insertion hole 105, further, the side portion of the terminal insertion hole 105 is provided with an auxiliary hole 9 communicated therewith, as shown in fig. 6, the auxiliary hole 9 is provided at the pin end of the wire end connecting portion 1, and the auxiliary hole 9 is a blind hole; the side of the metal terminal 106 is provided with a pop-up portion 1061, and the pop-up portion 1061 is close to the jack of the metal terminal 106, and the pop-up portion 1061 extends into the auxiliary hole 9 and abuts against the top of the auxiliary hole 9.

In the prior art, the use effect of the connector is reduced after the single metal terminal 106 in the connector is damaged, and the connector is generally directly replaced. If a single metal terminal 106 within the connector could be replaced, the cost of the connector would be reduced, thereby extending the useful life of the connector. Based on the above structure, the present application further provides the following embodiments:
specifically, as shown in fig. 7 and 8, the unlocking mechanism 10 is further included in the auxiliary hole 9, and in an initial state, the outer side surface of the pop-up portion 1061 abuts against the unlocking mechanism 10, and the top of the pop-up portion 1061 abuts against the inner top of the auxiliary hole 9. Specifically, the unlocking mechanism 10 includes a guide block 1001, a guide pin 1002 arranged at an inner end of the guide block 1001, a first spring 1003 sleeved on the guide pin 1002, and a protruding barb 1004 arranged on an inner side of the guide block 1001, the guide block 1001 is arranged in the auxiliary hole 9 in a penetrating manner, the protruding barb 1004 is arranged in the auxiliary hole 9 towards the terminal jack 105 in a clamping manner, and the protruding barb 1004 ensures that the guide block 1001 cannot be separated from the auxiliary hole 9. A guide hole 1005 is formed in the top of the auxiliary hole 9, the guide pin 1002 is inserted into the guide hole 1005, and the first spring 1003 is clamped between the top of the auxiliary hole 9 and the inner end of the guide block 1001.
Based on the above structure, in the initial state, the top of the pop-up portion 1061 abuts against the guide block 1001 and the top of the auxiliary hole 9, and at this time, no external force is applied, and the metal terminal 106 is stabilized in the terminal insertion hole 105; when the metal terminal 106 needs to be replaced, the clamping state of the first main body 101 and the second main body 102 is released, so that the clamping fixing relation of other parts of the metal terminal 106 is released, the guide block 1001 is pushed manually to move towards the inner side of the auxiliary hole 9, and in the moving process, the guide block 1001 and the protruding barbs 1004 extrude the bouncing portion 1061, so that the top of the bouncing portion 1061 is gradually restored into the terminal jack 105, and the metal terminal 106 is convenient to pull out outwards. Meanwhile, due to the shape of the raised barbs 1004, the extrusion effect of the bouncing portion 1061 can be more obvious, and the extruded bending degree of the bouncing portion 1061 is improved and the bouncing portion can be quickly separated. Meanwhile, when the metal terminal 106 is disengaged from the terminal insertion hole 105, the guide block 1001 is restored to the original position by the elastic force of the first spring 1003, and an accommodation space of the pop-up portion 1061 is reserved between the guide block 1001 and the inner top of the auxiliary hole 9.
