Abstract

The present disclosure relates to a crimper body and a crimper. The crimper body is applied to the crimper for crimping cables. The crimper body includes a body, which includes a fixed mold holder provided at one end of an upper portion of the body, and a protector. The protector is mounted to the body to reinforce and fix the fixed mold holder to rest of the body over the entire length of the fixed mold holder. The present disclosure further relates to the crimper including the crimper body. The crimper can effectively prevent fragments of the crimper body from dispersing when broken, and has the advantages of compact structure, light weight, and low cost.

First claim

What is claimed is:

1. A crimper body for a crimper for crimping cables, the crimper body comprising:
a body including a fixed die holder at one end of the body and a connecting portion at another end of the body for connecting with a power device, a transition portion between the fixed die holder and the connecting portion, and a reinforcing portion below the fixed die holder, the transition portion and the connecting portion for increasing strength of the body; and
a protector mounted to the body to reinforce and fix the fixed die holder to the body along an entire length of the fixed die holder, the protector including an arm portion and a fixing end portion arranged at an end of the arm portion and connected to the arm portion, wherein the protector is configured to reinforce and fix the fixed die holder to the body at a side portion and/or a back portion of the body;
wherein the arm portion includes a vertical extension portion, a length of the vertical extension portion being substantially equal to a length of the fixed die holder, and the vertical extension portion being fixed to a side portion of the fixed die holder and/or to a back portion of the reinforcing portion over the entire length of the fixed die holder,
wherein a through hole is defined at an end of the vertical extension portion of the arm portion, and the vertical extension portion is fixed to a surface of the side portion of the fixed die holder and/or to a surface of the back portion of the reinforcing portion by a fixing member extending through the through hole of the vertical extension portion.

2. The crimper body according to claim 1 , wherein the arm portion further includes a horizontal extension portion perpendicular to the vertical extension portion, and the horizontal extension portion matches planes of side portions of the transition portion and the connecting portion in a horizontal direction.

3. The crimper body according to claim 1 , wherein the protector includes two arm portions, and the two arm portions are parallel to each other.

4. The crimper body according to claim 1 , wherein the arm portion further includes an intermediate portion between the vertical extension portion and the fixing end portion, and the vertical extension portion and the intermediate portion match the surface of the entire back portion of the reinforcing portion.

5. The crimper body according to claim 1 , wherein the protector is sheet-shaped or chain-shaped.

6. The crimper body according to claim 1 , wherein the protector is made of flexible metal or high-strength plastic.

7. A crimper body for a crimper for crimping cables, the crimper body comprising:
a body including a fixed die holder at one end of the body and a connecting portion at another end of the body for connecting with a power device, a transition portion between the fixed die holder and the connecting portion, and a reinforcing portion below the fixed die holder, the transition portion and the connecting portion for increasing strength of the body; and
a protector mounted to the body to reinforce and fix the fixed die holder to the body along a length of the fixed die holder, the protector including an arm portion and a fixing end portion arranged at an end of the arm portion and connected to the arm portion, wherein the protector is configured to reinforce and fix the fixed die holder to the body at a side portion and/or a back portion of the body;
wherein a through hole is defined in the center of the fixing end portion, and the fixing end portion is fixed to an outer end surface of the connecting portion by a fixing member extending through the through hole of the fixing end portion.

8. A crimper body for a crimper for crimping cables, the crimper body comprising:
a body including a fixed die holder at one end of the body; and
a protector mounted to the body to reinforce and fix the fixed die holder to the body along a length of the fixed die holder;
wherein the protector is configured to reinforce and fix the fixed die holder to the body at a side portion and/or a back portion of the body;
wherein the body further includes a connecting portion at another end of the body for connecting with a power device, a transition portion between the fixed die holder and the connecting portion, and a reinforcing portion below the fixed die holder, the transition portion and the connecting portion for increasing strength of the body;
wherein the protector includes an arm portion and a fixing end portion arranged at an end of the arm portion and connected to the arm portion;
wherein a through hole is defined in the center of the fixing end portion, and the fixing end portion is fixed to an outer end surface of the connecting portion by a fixing member extending through the through hole of the fixing end portion.

9. The crimper body according to claim 8 , wherein the arm portion includes a vertical extension portion, a length of the vertical extension portion being substantially equal to a length of the fixed die holder, and the vertical extension portion being fixed to a side portion of the fixed die holder and/or to a back portion of the reinforcing portion over the entire length of the fixed die holder.

10. The crimper body according to claim 9 , wherein a through hole is defined at an end of the vertical extension portion of the arm portion, and the vertical extension portion is fixed to a surface of the side portion of the fixed die holder and/or to a surface of the back portion of the reinforcing portion by a fixing member extending through the through hole of the vertical extension portion.

11. The crimper body according to claim 9 , wherein the arm portion further includes a horizontal extension portion perpendicular to the vertical extension portion, and the horizontal extension portion matches planes of side portions of the transition portion and the connecting portion in a horizontal direction.

12. The crimper body according to claim 11 , wherein the protector includes two arm portions, and the two arm portions are parallel to each other.

13. The crimper body according to claim 9 , wherein the arm portion further includes an intermediate portion between the vertical extension portion and the fixing end portion, and the vertical extension portion and the intermediate portion match the surface of the entire back portion of the reinforcing portion.

14. The crimper body according to claim 8 , wherein the protector is sheet-shaped or chain-shaped.

15. The crimper body according to claim 8 , wherein the protector is made of flexible metal or high-strength plastic.

16. The crimper body according to claim 8 , wherein the protector is mounted to the body along an entire length of the fixed die holder.

17. The crimper body according to claim 16 , further comprising:
a crimper including the crimper body,
a movable die holder, which is mounted in the body of the crimper body to crimp a cable together with the fixed die holder; and
a power device, which is configured to provide a force to the movable die holder to push the movable die holder toward the fixed die holder.
