PERFORMANCE SPECIFICATION FOR CABLE-TO-TERMINAL ELECTRICAL CRIMP

端子压接的性能规范

1. SCOPE范围

IMPORTANT NOTICE: In any intended vehicle application, if the products covered by

this specification are, or may be, subjected to conditions beyond those described in this

document, They must pass special tests simulating the actual conditions to be

encountered before they can be considered acceptable for actual vehicle application.

Products certified by their supplier as having passed specific applicable portions of this

specification are not to be used in applications where conditions may exceed those for

which the product has been satisfactorily Authorized Person is the final

authority as to what tests are to be performed on his or her parts and for what purpose

these tests are required. He or she is also the final authority for resolving any questions

related to testing to this specification and to authorizing any deviations to the equipment

or procedures contained in this specification. Any such deviation must be documented

and included in the final test report.

重要提示:在任何汽车应用中,对于本规范没有涉及到的情况,产品必须通过相应的特殊

试验,该试验的试验条件应该模仿汽车在实际使用中的条件。对于通过了该规范中要求的

试验的产品,使用时也不能应用于超过该试验条件的场合。权威人士是最终有权指出他或

她的产品需要做哪些试验并且这些试验有哪些目的的人。对于解决该规范中出现的任何试

验问题,对于与该规范中包含的试验设备和试验程序相违背的情况,他或她仍然是有最终

决定权的人。试验中出现的任何不符合性都必须作记录,并记录在最终试验报告中。

1. This specification defines basic test methods and requirements for solder-less crimped

connections.

1.在该规范中定义了关于纯压接连接(没有焊接)的基本试验方法和试验要求。

2. Crimp applications validated to this specification supercede any crimp information on

Ford, GM, or DaimlerChrysler component prints. It is preferred that the terminal supplier

do testing and selection of crimp tooling and supply detailed crimp information or make

crimp tooling available to the wiring assembly supplier actually doing the production

crimping. If the wiring supplier deviates from this information or it is not available, then the

responsibility for testing to this specification or getting approval from the customer with

appropriate test data showing that the crimp will function in it’s intended circuit lies with

the wiring harness supplier.

2.该生效的压接规范代替了Ford,GM, or DaimlerChrysler的任何压接信息。端子供应商做试

验和选择压接工具和提供详细的压接信息,或需要端子压接的供应商制作压接工具。假如

与该规范违背或不适用,那么该规范的试验或关于证明符合预期压接功能的试验数据得到

顾客的批准的责任将由线束供应商承担。

3. New or revised terminals shall be designed to meet this specification.

3.新设计或修改的端子设计需要符合该规范。

4. All new crimp applications shall meet this specification. New crimp applications are

defined as terminal/wire crimp combinations not previously specified on Ford, GM, or

DaimlerChrysler vehicle wiring harness assemblies. Existing crimp applications may be

carried over if approved by the customer engineering department.

4.所有新的压接应用需要符合该规范。新的压接应用定义为端子/导线的压接连接,不是以

前在Ford, GM、DaimlerChrysler汽车应用中规定的线束装配。如果顾客的工程部门批准,

现存的压接应用可以继续使用。

5. Electrical tests in this specification have been proven by past experience to ensure that

crimps will meet the requirements in SAE/USCAR-2 and SAE/USCAR-20 by including

Thermal Shock, Temperature Humidity, and Power Current Cycling. Testing and

electrical acceptance criteria will detect defects in crimp tooling geometry, plating quality,

inadequate strand distribution in the grip, or cable stranding. Crimp applications that have

passed SAE/USCAR-2 and SAE/USCAR-20 normally have only passed the nominal

crimp height and usually only with the largest gauge size. Therefore, crimps within the

production crimp height range may not necessarily pass this test.

5.该规范中的电性能试验已经由过去的经验证明能确保压接符合SAE/USCAR-2和

SAE/USCAR-20规范要求,其中包含了热冲击、温度循环和电流循环试验。电性能试验和

电性能试验接收标准,该接收标准涉及了检测压接工具的几何缺陷,镀层的质量,不合理

的压线角(包括没有充分包住线芯或电缆线芯,所包芯线两边不对称)、芯线断股。已经

通过SAE/USCAR-2和SAE/USCAR-20规范的压接情况通常只是通过名义压接高度并且通

常只用最大线规压接。所以对于那些在此压接高度范围内的情况没有必要做试验。

6. Procedures included within this specification are intended to cover performance testing

at development of electrical terminal crimps that are part of the electrical connection

systems in low voltage (0 - 48 VDC) road vehicle applications at ambient temperatures of

125 C maximum. The OEM customer must approve use of these test procedures for

use at voltages and temperatures beyond these limits.

6.该规范中包含的程序覆盖了端子压接开发过程中需要思考的性能试验,端子压接是电连

接系统的一部分,该电连接系统应用在电压是0 - 48 VDC,最高环境温度是125 C的汽车

中。对于超过该电压和该环境温度的情况,如果要使用该规范中的试验程序,需得到OEM

顾客的批准。

7. These procedures are applicable only to terminals used for in-line, header, edge board,

and device connector systems.

7.该程序只是适用于以下应用情况中的端子:in-line, header, edge board, and device

connector systems.

1.1 Crimping Parameters

1.1压接参数

1.1.1 The Crimp connection performance is characterized by:

Mechanical performance is measured by terminal to conductor Pull-Out Force.

Electrical performance is measured by terminal-to-conductor Crimp Resistance.

1.1.1压接连接的性能由以下方法来判断:

机械性能通过测试端子与导线的拉脱力来判断;

电性能通过测量端子与导线的压接电阻来判断。

1.1.2 The geometry of a conductor crimp is characterized by:

Conductor crimp height (CCH)

Conductor crimp width (CCW)

Insulation crimp height (ICH)

Insulation crimp width (ICW)

Cut-off

End of conductor
